Talk notes from 1988: "The concept of radical novelties is of contemporary significance because, while we are ill-prepared to cope with them, science and technology have now shown themselves expert at inflicting them upon us. Earlier scientific examples are the theory of relativity and quantum mechanics; later technological examples are the atom bomb and the pill." The radical novelty of the automatic computer can be found in large numbers and digital (as opposed to analog) implementation: small changes, potentially big effects. Towards the final third this amazing talk becomes a bit uptight.

In October of 1994, I’d just started as an honest-to-goodness videogame programmer at a small startup called SingleTrac – which later went on to fame and glory (but unfortunately not much in the way of fortune) with such titles as Warhawk, the Twisted Metal series, and the Jet Moto series. But at the time, the company was less than 20 employees in size and had only been officially in business for about a month. It was sometime in my first week – possibly my first or second day. In the main engineering room, there was a whoop and cry of success. Our company financial controller and acting HR lady, Jen, came in to see what incredible things the engineers and artists had come up with. Everyone was staring at a television set hooked up to a development box for the Sony Playstation. There, on the screen, against a single-color background, was a black triangle.

"We came to refer to certain types of accomplishments as 'black triangles.' These are important accomplishments that take a lot of effort to achieve, but upon completion you don’t have much to show for it."

Sometimes the big victories look pedestrian at first glance.

A great term for those things that take so much effort for seemingly little output.

"Nine times out of ten, the first impression someone gives you is exactly who they are. We choose not to see it because we need the money, or we want the situation to be different. But if someone rubs you the wrong way at the first meeting, chances are, it’s only going to get worse."

It can be very intimidating to turn down work, especially in these uncertain economic times.

Here I will walk you through and at the end of the article we will have created a fully functional Firefox extension!

I've wondered what goes into coding those things.

Sometimes you want a single object to behave differently depending on what state it’s in. For instance, a traffic light has a different color depending on whether it is informing people that they should stop, slow down, or proceed. Or a user account object might behave differently depending on whether the account is in the “confirmed” state. AlterEgo can help you set up these state-based object “personalities”. AlterEgo will help you to define a set of valid states for your objects, and to define the allowable transitions between states. The real strength of AlterEgo, however, is in defining separate behaviors for each state that the object is in. Underneath the covers, AlterEgo will arrange for your object to delegate to a different state object depending on what state it is in. You can either explicitly define these state objects as classes, or use a concise DSL provided by AlterEgo.

A state machine plugin which allows each state to have different methods and behaviours.

AlterEgo is a Ruby implementation of the State pattern as described by the Gang of Four. It differs from other Ruby state machine libraries in that it focuses on providing polymorphic behavior based on object state.

"Having spent a lot of time scripting around the binaries and trying to manage timeouts, standard out/in/error pipes, authentication, arguments and options all through ‘’subprocess”, ”popen2”, etc., I’m here to tell you wrapping command line binaries is prone to error, difficult to test, and painful to maintain."

OpenSSH is the ubiquitous method of remote access for secure remote-machine login and file transfers.

5 obscure HTML tags

With the rising popularity of CSS for styling, many web developers and users alike have become alienated from the good old HTML tags. Only a handful of these tags are used in the markup of web pages today. Most of them have got limited representation and some of them are entirely forgotten. I decided to round up a couple of HTML tags that perhaps should be used a little more often than they actually are.

nice overview of programming languages

As I do my professional and personal work, I am always looking for the best tool for the job. In software development, there are several programming languages that can be used for a wide variety of reasons. I am often asked by people new to software development what is the best language to learn. They get confused when I ask them what they plan on doing. The reason is that people think there is going to be a best language for everything. However, everyone knows that there is no silver bullet. On the other hand, there are some languages which are better suited or more widely used in specific areas. So, given that idea, I came up with a list.

For each canvas element you can use a "context" (think about a page in a drawing pad), into which you can issue JavaScript commands to draw anything you want. Browsers can implement multiple canvas contexts and the different APIs provide the drawing functionality.

Most programmers are not just desktop programmers, web programmers or scripting gurus - they are often all of the above.

Over time, these developers typically archive a library of these reusable modules in order to save time the next time they need to do the same task.

One of the latest (sort of) crazes sweeping the net is APIs, more specifically those that leverage REST. It’s really no surprise either, as consuming REST APIs is so incredibly easy… in any language. It’s also incredibly easy to create them as you essentially use nothing more than an HTTP spec that has existed for ages. One of the few things that I give Rails credit for is its well thought-out REST support, both for providing and consuming these APIs (as its been explained by all the Rails fanboys I work with).

Why &#92; was used for paths in DOS.

The reason why DOS (and subsequently Windows) went with the backslash character to convey path information, instead of UNIX's forward-slash.

Why is there a "&#92;" key on the keyboard in the first place? As far as I know, they aren't used in English grammar, and to this day, most common users don't know which is "back" and which is "forward."

So you want to write a script that sites all over the web can use to access your REST API, eh? Well, that would be pretty straightforward if it weren’t for two things: 1. browser same-origin restrictions on XMLHttpRequests (XHRs) and inter-window/frame access 2. the lack of wide browser support for HTML 5-style message passing between windows. The Same-Origin Policy and its minor browser-specific variations are detailed elsewhere, so I’ll just summarize it with a few key points. I use the term window to mean window object, which can be a top-level page or reside inside a frame or iframe.

With jQuery 1.3.2 out the door I've been looking for more ways to profile and optimize jQuery. Previously I did a survey of jQuery-using sites to figure out which selectors they were using. This led to the construction of the new Sizzle Selector Engine which targeted those selectors for improvement. Additionally, I constructed a deep profiling plugin for jQuery which helped to spot methods that were taking a long time to run in live jQuery sites. This helped bring about the improvements in jQuery 1.2.6, 1.3, and 1.3.2.

Due to performance issues on Pentium IV processors with existing software interrupt method, an alternative system call entry mechanism was implemented using SYSENTER/SYSEXIT instructions available on Pentium II+ processors. This article explores this new mechanism. Discussion is limited to x86 architecture and all source code listings are based on linux kernel 2.6.15.6."

Technical Debt is a wonderful metaphor developed by Ward Cunningham to help us think about this problem. In this metaphor, doing things the quick and dirty way sets us up with a technical debt, which is similar to a financial debt. Like a financial debt, the technical debt incurs interest payments, which come in the form of the extra effort that we have to do in future development because of the quick and dirty design choice. We can choose to continue paying the interest, or we can pay down the principal by refactoring the quick and dirty design into the better design. Although it costs to pay down the principal, we gain by reduced interest payments in the future.

Could a modern evolutionary algorithm and a huge input sample discover a better [keyboard layout]?

Using an experimental function & selection to discover a more efficient keyboard layout than Dvorak

Other layouts for a standard 3-row keyboard exist (as well as some interesting nonstandard arrangements). I have been using the Dvorak keyboard layout for about a year now. I like it a lot for my daily work, which involves a lot of typing. I used to feel a numbness of the backs of my hands after a long day with QWERTY, but I don't with Dvorak. And quantified measurements bear out its efficiency relative to QWERTY. (I acknowledge the argument that learning Dvorak also got me to type with the right fingers on the right keys, but I don't think that that's the whole story.)

“Redis is a key-value database. It is similar to memcached but the dataset is not volatile, and values can be strings, exactly like in memcached, but also lists and sets with atomic operations to push/pop elements. “In order to be very fast but at the same time persistent the whole dataset is taken in memory and from time to time and/or when a number of changes to the dataset are performed it is written asynchronously on disk. You may lost the last few queries that is acceptable in many applications but it is as fast as an in memory DB (beta 6 of Redis includes initial support for master-slave replication in order to solve this problem by redundancy).”

Trek Rails Forms microformat This article has been updated to reflect the latest patterns in Rails 2.3 edge (based mostly on this commit) If you’ve been relying on Rails form helpers to generate forms, then you may have missed the interesting little microformat used to pass application data to and fro. In case you didn’t know, form data is passed as part of the request body as a set of key/values pairs in plain text (if you’re using get as a method for a form, it’s that url section like this: ?name=widget12&price=22). The name attribute of the form inputs are the keys (here name and price), and the value is whatever the user entered or selected (widget12 and 22). Most languages/frameworks for the web will reconstitute these pairs as objects accessible to the programmer. For example <input name='widget_name' /> is accessed with $_POST["widget_name"] in php, self.request.get("widget_name") on App Engine, and params[:widget_name] in Rails. This format can only pass a single value f

The problem is that trying to copy one company's model is a fool's errand. It's hard to figure out which part of the Starbucks formula made the business a smash hit while so many of its rivals failed. Starbucks's success is the product of a combination of factors that came together in precisely the right way at precisely the right time. It's nearly impossible to isolate which one was the most important. You would probably have to look at the hundreds of small coffee chains that didn't make it big before you stood a chance of seeing what really distinguished Starbucks.

70 New, Useful AJAX And JavaScript Techniques

As the Web grows and becomes more dynamic, more and more websites have user-generated content and tools that greatly improve the user experience in terms of usability and accessibility. Interactive solutions for lightboxes, form validation, navigation, upload, auto-complete, image cropping, slideshows, tool tips, sliders and tables are being developed that use nifty JavaScript and AJAX scripts. When using these, developers have to carefully consider many subtle techniques to help users get things done. In this article, we present 70 new and useful JavaScript and AJAX techniques, all of which are of the highest quality and are more or less easy to configure. You will also find some very useful but better known techniques to use on almost any project you work on. jQuery, MooTools, Prototype and script.aculo.us are used in these examples, so every taste gets its due.

Can Rhythmic Analysis Demonstrate the Use of Robotic Beats?

I’ve always been curious about which drummers use a click track and which don’t, so I thought it might be fun to try to build a click track detector using the Echo Nest remix SDK ( remix is a Python library that allows you to analyze and manipulate music). In my first attempt, I used remix to analyze a track and then I just printed out the duration of each beat in a song and used gnuplot to plot the data. The results weren’t so good - the plot was rather noisy. It turns out there’s quite a bit of variation from beat to beat. In my second attempt I averaged the beat durations over a short window, and the resulting plot was quite good.

Last week I did a review of 6 jQuery plugins that were great for implementing charts.

How to Fix Memory Leaks in Java

You may be running non-free programs on your computer every day without realizing it—through your web browser. In the free software community, the idea that non-free programs mistreat their users is familiar. Some of us refuse entirely to install proprietary software, and many others consider non-freedom a strike against the program. Many users are aware that this issue applies to the plug-ins that browsers offer to install, since they can be free or non-free. But browsers run other non-free programs which they don't ask you about or even tell you about—programs that web pages contain or link to. These programs are most often written in Javascript, though other languages are also used. Javascript (officially called ECMAscript, but few use that name) was once used for minor frills in web pages, such as cute but inessential navigation and display features. It was acceptable to consider these as mere extensions of HTML markup, rather than as true software; they did not constitute a sig

Fortunately, there are cross-platform Python bindings for Qt. The downside, however, is that packaging PyQt applications so that they can be deployed to users on Windows and Mac OS X is an immensely frustrating and arcane process. I declared victory last week after spending several hours battling with MacPorts and distutils. Now that I have unlocked the toolkit's dark mysteries, I can show you the hidden secrets that will allow you to achieve mastery of the alchemical art of cross-platform PyQt application deployment.

Ars delves into the arcane depths of cross-platform application deployment in this detailed tutorial which will teach you how to package PyQt software for Windows and Mac OS X.

Object-oriented programming was supposed to unify the perspectives of the programmer and the end user in computer code: a boon both to usability and program comprehension. While objects capture structure well, they fail to capture system action. DCI is a vision to capture the end user cognitive model of roles and interactions between them.

Below I've collected some links to advanced computer science courses on-line. I'm concentrating on courses with good lecture notes, rather than video lectures, and I'm applying a rather arbitrary filter for quality (otherwise this becomes a directory with less semantic utility). This is the good stuff! But only a subset of it - any recommendations for good courses are gratefully received. I'm mainly interested in systems, data-structures and mathematics, so reserve the right to choose topics at will.

<blockquote>...the true accidental brilliance of Java is that it has created a very smooth path for its own replacements, even if Java itself has reached the point where it can no longer evolve.</blockquote>

In a recent discussion, there were assertions that C++ was a poorly-designed language. I was on the C++ Standards Committee for 8 years, and saw the decisions take place. I think it's helpful to understand the language choices for both C++ and Java in order to see the bigger perspective.

ever, users like know that there is someone who will be happy to help them out if they need it. That is the main purpose of offering customer support — decreasing the perceived risk of using your software by demonstrating that there is a safety net. (This is one reason you should write your support page with an eye to it being seen by someone who isn’t even using your software.)

2) Design OSS projects, particularly the 99% that are relevant to this discussion, routinely do not allocate resources to creating attractive designs. For whatever reason, opened source graphical work is still rather rare, most developers (myself included) have the artistic skill of inept mole rats, and the obvious pay-somebody-who-does-it-better solution runs into the problem that the typical OSS project has no budget and no patience to deal with “unfree” licenses, which are the only kind commercially available stock icons have.

Taking a brief step back, this article is the third of a series. In the first episode we posed a puzzle: Starting with a list of runners ordered by finishing time, select a sublist of runners who are getting younger. What is the longest such sublist? In the second episode we coded up a brute force solution which searched all possible sublists to find an optimal solution. Although the code was simple and succinct, its exponential complexity made it unsuitable for practical use. In this episode we’ll discuss an elegant algorithm which solves our particular problem as a special case. On the way we’ll visit dynamic programming, Python decorators, version control and genetics.

Be lazy // Don't if ($('#item').get(0)) { $('#item').someFunction(); } // Or if ($('#item').length) { $('#item').someFunction(); } // Just do $('#item').someFunction(); jQuery will call the function only if there is a match, no need to double check. 2. Use shortcuts // You can but.. $(document).ready(function(){ // ... }); // There is a shorter equivalent $(function(){ // ... }); It should be well known, but obviously it is not. 3. Chain // Don't $('#frame').fadeIn(); $('#frame .title').show(); $('#frame a:visited').hide; // Do $('#frame').fadeIn() .find('.title').show().end() .find('a:visited').hide(); Unnecessary DOM traversal is a expensive operation, avoid it when possible. 4. Group queries // Ugly $('div.close').click(closeCallback); $('button.close').click(closeCallback); $('input.close').click(closeCallback); // Not ugly $('div.close, button.close, input.close') .clic

The genius behind Google's web browser

Chrome attracted more than 10 million users in its first 100 days. Although that’s an impressive number, it still only translates into about 1 per cent of browser usage online. It will be a while before it can compete with Firefox, Internet Explorer and others. In December last year, Google announced that Chrome was now out of its development, or Beta, phase and is ready to be shipped as a pre-installed browser on some PCs. This could rapidly increase the number of users. Moreover, the European Commission’s antitrust battle with Microsoft over, among other things, how its own browser, Internet Explorer, is integrated into its Windows operating system may give competitors a chance Legislation and market share aside, the technical challenge has been laid down. “Microsoft will have to build something better than V8,” Bak says. Most tech watchers doubt that they will manage to any time soon: in tests, V8 processes JavaScript 56 times faster than the most used version of Internet Explorer.

After 2 1/2 years of blood, sweat, tears, and the occasional Jägermeister, I’m finally officially announcing a project I’ve been quietly working on: state_machine.

Google's Python engineers have launched a new project called Unladen Swallow that seeks to improve the performance of the Python programming language. One of the project's goals is to replace the Python virtual machine with an LLVM-based JIT.

Google's Python engineers have launched a new project called Unladen Swallow, which aims to bring a major performance boost to the Python programming language by making runtime speed five times faster. The project is being implemented as a branch of the conventional CPython runtime and will be fully source-compatible with regular Python applications and native extensions. This will make it possible to eventually merge the improvements into Python trunk. The goal of the Unladen Swallow project is to use LLVM, the Low Level Virtual Machine compiler infrastructure, to build a just-in-time (JIT) compilation engine that can replace Python's own specialized virtual machine. This approach offers a number of significant advantages. As the developers describe in the project plan, the project will make it possible to transition Python to a register-based virtual machine and will pave the way for future optimizations. Adopting LLVM could also potentially open the door for more seamlessly integr

g system, mobile platform, or web platform. Basically, if you want to share a short thought, one to many, Twitter is a transport-independent way to do that. In a broader technical sense, we see ourselves as a short messaging layer for the internet. We’ve been described as a “telegraph for web 2.0.” One of the things that’s core to our business is providing open APIs for everything you can do on the website. So all the functionality that’s available there for users is also available for developers to access programmatically. That’s Twitter in a nutshell. Twitter started as a hack project at a company called ODEO, which was focused on podcasting. As ODEO was having some troubles in its latter days as a company, they started experimenting, to keep engineers involved by letting them play around with ideas they had on the side. One of the engineers, Jack Dorsey, had been really interested in status. He was looking at his AIM buddy list, and seeing that all of these guys were saying, “I’m w

he ie6-upgrade-warning is a little script (7.9kb) that displays a warning message politely informing the user to upgrade the browser to a newer version (links to newest IE, Firefox, Opera, Safari, Chrome are provided). The webpage is still visible behind a transparent background, but access to it is prevented. The idea is to force users to upgrade from IE6 and avoid the website from a bad reputation that website is not rendering correctly in IE6.

Keeping your database simple and fast is often difficult if you use higher level frameworks such as ActiveRecords in Ruby or Java object persistence technologies such as Hibernate. There is a lot of magic that is happening out of sight that you have no control over. If you then have to scale your application it is often the relational database that these technologies require that becomes the performance and scaling bottleneck. Often requiring complex custom implementations of partitioning and sharding to make it work. The AWS services Amazon S3 and Amazon SimpleDB were designed to handle the dominant storage usage patterns within Amazon and they greatly reduced our need to rely on relational storage for scaling our systems. But it is almost never the case that a single storage technique is used in applications and services that need to operate at enterprise scale. For example it is a common pattern that objects stored in S3 using a primary key, have a collection of secondary keys (e.g

Most of the mistakes have a seductive appeal. Do you need to rescue a project that's behind schedule? Add more people! Do you want to reduce your schedule? Schedule more aggressively! Is one of your key contributors aggravating the rest of the team? Wait until the end of the project to fire him! Do you have a rush project to complete?

Static images of sorting algorithms, pretty neat!

"This whole thing started partly as an excuse to get familiar with the Cairo graphics library. It produces beautiful, clean images, and appears to be both portable and well designed. It also comes with a set of Python bindings that are maintained as part of the project itself - a big plus in my books. Firefox 3 will use Cairo as its standard rendering back end, which will instantly make it one of the most widely used vector graphics libraries out there. "

I dislike animated sorting algorithm visualisations - there's too much of an air of hocus-pocus about them. Something impressive and complicated happens on screen, but more often than not the audience is left mystified. I think their creators must also know that they have precious little explanatory value, because the better ones are sexed up with play-by-play doodles, added, one feels, as an apologetic afterthought by some particularly dorky sportscaster. Nevertheless I've been unable to find a single attempt to visualise a sorting algorithm statically (if you know of any, please drop me a line). So, presented below are the results of a pleasant evening with some nice Scotch and the third volume of Knuth. First, here's a taster - a static visualisation of heapsort: Heapsort I think these simple static visualisations are much clearer than most animated attempts - and they have the added benefit of also being, to my not entirely unbiased eye, rather beautiful.

Overview Eigen is a C++ template library for linear algebra: vectors, matrices, and related algorithms. It is: * Versatile. (See modules and tutorial). Eigen handles, without code duplication, and in a completely integrated way: o both fixed-size and dynamic-size matrices and vectors. o both dense and sparse (the latter is still experimental) matrices and vectors. o both plain matrices/vectors and abstract expressions. o both column-major (the default) and row-major matrix storage. o both basic matrix/vector manipulation and many more advanced, specialized modules providing algorithms for linear algebra, geometry, quaternions, or advanced array manipulation. * Fast. (See benchmark). o Expression templates allow to intelligently remove temporaries and enable lazy evaluation, when that is appropriate -- Eigen takes care of this automatically and handles aliasing too in most cases. o Explicit vectorization is

Services like Flickr, Delicious, and Twitter all offer JavaScript badges or widgets you can add to your site. But if you already use a JavaScript framework on your site, like jQuery, why would you want to add more JavaScript? Besides, it’s more fun to make your own. All of these services also offer a JSON format feed API, and rolling your own widget is easy.

In our company, code reviews play an integral part in the development process for making quality software. We opt for a mentor style approach with Wufoo, where a developer works on a segment for a period of time and then passes it up to a more experienced developer for review. We really like this approach because it means more developers become familiar with the foundation of different code level services. More importantly, they act as an additional safeguard against security holes, memory leaks, poor queries and heavy file structures. Unfortunately, these reviews are also very time consuming and in a small team can sometimes be an inconvenience to the reviewer — another developer with their own todo list to accomplish.

Two links to Berkun in one day! But there is a great axiom contained within: "Requirements is not Design."

The one book anyone working on requirements needs to read is Exploring Requirements by Gerald Weinberg. It points out most of the stupidity that goes on, explains avoidance tactics, and clearly expresses how requirements are part of the design process - that good problem solving techniques can quickly make your requirements documents better than ever.

Here’s a requirements list: Make a $5 car that goes 500 miles per hour, weighs 10 lbs, and is invisible. Those are very clear requirements. They’re also impossible.

"I don’t want an engineer working on something s/he thinks is stupid. How I can expect them to do good work on something they find stupid?"

1: Requirements is not Design. 2: Too Many Cooks. I like Berkun.

(1) Requirements may be impossible to implement. (2) Requirements writing is hard when no single person has the knowledge and authority.

QuirksBlog: Introduction to W3C Widgets

Essentially, a widget is a local HTML/CSS/JavaScript web application. A mobile phone user downloads a widget once, and from that moment on he has a web application stored locally on his mobile phone. Although currently widgets are mostly used for relatively limited functions such as clocks, RSS readers, or Twitter or Flickr clients, as well as for games, there’s no theoretical reason why they couldn’t contain a complete, complicated, JavaScript-heavy web application; for instance a mobile-optimised spreadsheet application.

As I start on my venture to really start using jQuery a lot more outside of simple form validation, I wanted to share some really great links I found lately that once again got me fired up about jQuery. This is part of my initial research into more jQuery as we’re going to be using it extensively in our new redesign for the .com I am working at so might as well dig more in now. I’ve used jQuery in the past and know its power & philosophy behind unobtrusive JavaScript and JQuery, but have not yet worked on anything extremely extensive outside aiding to help create a custom validation control in MVC using jQuery in the past. Personally (some agree, some don’t) I think the jQuery Site’s tutorials & API docs are only “fair” at this point in time, so you need a lot of links to supplement the learning process. While yes, you keep hearing that jQuery makes things “easier”, no matter what you hear, the learning curve is a still bit steep at first for even some of the best developers I’ve

Introduction I love to use JavaScript in unexpected ways, to create code that looks like it shouldn't work but does, or produces some unexpected behavior. This may sound trivial, but the results I've found lead to some very useful techniques. Each of the techniques described can be used for XSS filter evasion, which was my original intention when developing them. However, learning such JavaScript can dramatically increase your knowledge of the language, helping you become better at cleaning up input, and increase web application security. So read on and enjoy my weird and wonderful JavaScript hacks. RegExp replace can execute code When using regular expressions with replace the second argument supports a function assignment. In Opera it seems you can use this argument to execute code. For example, check out the code snippet below: 'XSS'.replace(/XSS/g,alert) This results in alert('XSS'); this works because the match from the RegExp is passed to the alert function as an argument.

A few weeks ago, I sent the following in a email to a co-worker asking for input on designing REST APIs in Django. Since then, I’ve quoted myself a few times; I thought these thoughts would be worth a (slightly edited) public home. I think the best way to dive in terms of mistakes to avoid. If you poke around you’ll find a couple-three different stabs at writing a generic REST API module for Django. So, with no further ado, some REST “worst practices:” Conflating models and resources In the REST world, the resource is key, and it’s really tempting to simply look at a Django model and make a direct link between resources and models — one model, one resource. This fails, though, as soon as you need to provide any sort of aggregated resource, and it really fails with highly denormalized models. Think about a Superhero model: a single GET /heros/superman/ ought to return all his vital stats along with a list of related Power objects, a list of his related Friend objects, etc. So the dat

Traditional SQL databases with "ACID" properties (Atomicity, Consistency, Isolation and Durability) give strong guarantees about what happens when data is stored and retrieved. These guarantees make it easier for application developers, freeing them from thinking about exactly how the data is stored and indexed, or even which database is running. However, these guarantees come with a cost.

article about data architecture for facebook's photo system. Seems interesting

The Photos application is one of Facebook’s most popular features. Up to date, users have uploaded over 15 billion photos which makes Facebook the biggest photo sharing website. For each uploaded photo, Facebook generates and stores four images of different sizes, which translates to a total of 60 billion images and 1.5PB of storage. The current growth rate is 220 million new photos per week, which translates to 25TB of additional storage consumed weekly. At the peak there are 550,000 images served per second. These numbers pose a significant challenge for the Facebook photo storage infrastructure. NFS photo infrastructure The old photo infrastructure consisted of several tiers: * Upload tier receives users’ photo uploads, scales the original images and saves them on the NFS storage tier. * Photo serving tier receives HTTP requests for photo images and serves them from the NFS storage tier. * NFS storage tier built on top of commercial storage appliances. Since each ima

Since each image is stored in its own file, there is an enormous amount of metadata generated on the storage tier due to the namespace directories and file inodes. The amount of metadata far exceeds the caching abilities of the NFS storage tier, resulting in multiple I/O operations per photo upload or read request. The whole photo serving infrastructure is bottlenecked on the high metadata overhead of the NFS storage tier, which is one of the reasons why Facebook relies heavily on CDNs to serve photos. Two additional optimizations were deployed in order to mitigate this problem to some degree:

At this point, I'd like to take a moment to speak to you about the Adobe PSD format. PSD is not a good format. PSD is not even a bad format. Calling it such would be an insult to other bad formats, such as PCX or JPEG. No, PSD is an abysmal format. Having worked on this code for several weeks now, my hate for PSD has grown to a raging fire that burns with the fierce passion of a million suns. If there are two different ways of doing something, PSD will do both, in different places. It will then make up three more ways no sane human would think of, and do those too. PSD makes inconsistency an art form. Why, for instance, did it suddenly decide that *these* particular chunks should be aligned to four bytes, and that this alignement should *not* be included in the size? Other chunks in other places are either unaligned...

We all can relate, bro.

// Earlier, I tried to get a hold of the latest specs for the PSD file format. To do this, // I had to apply to them for permission to apply to them to have them consider sending // me this sacred tome. This would have involved faxing them a copy of some document or // other, probably signed in blood. I can only imagine that they make this process so // difficult because they are intensely ashamed of having created this abomination. I // was naturally not gullible enough to go through with this procedure, but if I had done // so, I would have printed out every single page of the spec, and set them all on fire. // Were it within my power, I would gather every single copy of those specs, and launch // them on a spaceship directly into the sun. //

Cloud computing refers to the utilization of shared, elastic resources and processing power accessed via the Internet. In some ways, it hails the reversion to the golden age of time-sharing but with significant improvements to the distribution philosophies underlying the delivery infrastructure.

George emailed me with an interesting question. Paraphrasing George, liberally, what's are some good ways to keep developers sharpening the saw - Covey Habit #7? There's been lots of talk about being a better developer, but what about the unmotivated masses? (Don't worry, we can talk about them, because, since they are unmotivated, they aren't reading blogs.) ;) The assumption being that for every totally-amped developer who is always striving to get better, there's at least 10 developers who are saying, "Hey, it's 5:01pm, I've just checked in massive changes, can I punch out?" Here's some ideas, some mine, some Georges. I'm interested in yours:

This article is a crash course in writing maintainable JavaScript. We'll add features to a running example by iteratively following a simple principle: write a unit test, make it pass. Each test will serve as a quality feedback loop, creating both a safety net and an executable form of documentation for anyone who wants to change the production code. By starting each feature with a simple failing test we ensure that all features are tested. We avoid the cost of rewriting code to test it later. This is particularly valuable given the fact that JavaScript developers have so much rope to hang themselves with - consider how much global mutable state there is between the DOM API and the language itself.

Why HTTP? The world doesn’t need another arbitrary binary protocol. Just use HTTP. Your life will be simpler. Originally this came up when scaling a gaggle of MySQL machines. I would have killed for a reliable proxy. It’s with this in mind that I’ve come up with my list of things that HTTP has that an arbitrary protocol will have to rebuild. Anytime you choose to use a service based on a non-HTTP protocol, look over this list and think carefully about what you’re giving up.

I like how this posts list out some of the great reasons to just use HTTP and the method of interop communication. So much is already built on HTTP and there are more than enough great tools ubiquitously available for interacting and communication over HTTP. The post also has a long discussion thread.

It's approaching two weeks now since Ruby 1.9.1 was released, bringing with it not only a whole stack of extra performance and a new VM, but also a lot of compatibility issues. No pain, no gain! Thankfully, the Ruby community in its typical way has got to blogging, writing scripts, and what not, resulting in a flurry of useful links and resources for those brave enough to test the Ruby 1.9.1 waters. So here come 23 useful Ruby 1.9.1 links and resources! If you have any others you wish to add, please leave a comment as people will be checking those out too.

This page is about the Nimrod programming language, which combines Lisp's power with Python's readability and C's performance.

Nimrod Programming Language - efficient, expressive, elegant, statically typed, imperative, procedural, object-oriented, functional and generic

Nimrod is a new statically typed, imperative programming language, that supports procedural, object oriented, functional and generic programming styles while remaining simple and efficient. A special feature that Nimrod inherited from Lisp is that Nimrod's abstract syntax tree (AST) is part of the specification - this allows a powerful macro system which allows domain specific languages. Nimrod is a compiled, garbage-collected systems programming language which has an excellent productivity/performance ratio. Nimrod's design focuses on the 3E: efficiency, expressiveness, elegance (in the order of priority)...

Uma história para descrever o funcionamento interno do Git

simple, but extremely powerful system. Most people try to teach Git by demonstrating a few dozen commands and then yelling “tadaaaaa.” I believe this method is flawed. Such a treatment may leave you with the ability to use Git to perform simple tasks, but the Git commands will still feel like magical incantations. Doing anything out of the ordinary will be terrifying. Until you understand the concepts upon which Git is built, you’ll feel like a stranger in a foreign land.

"The following parable will take you on a journey through the creation of a Git-like system from the ground up. Understanding the concepts presented here will be the most valuable thing you can do to prepare yourself to harness the full power of Git. The concepts themselves are quite simple, but allow for an amazing wealth of functionality to spring into existence. Read this parable all the way through and you should have very little trouble mastering the various Git commands and wielding the awesome power that Git makes available to you."

The Internet and the networking world in general have changed in very significant ways since the sockets API was first developed, but in many ways the API has had the effect of narrowing the way in which developers think about and write networked applications. This article begins by briefly examining some of the conditions present when the sockets API was developed and considers how those conditions shaped the way in which networking code was written. The remainder of the article looks at ways in which developers have tried to get around some of the inherent limitations in the API and talks about the future of sockets in a changing networked world.

"High bandwidth, low latency, and multihoming challenge the sockets API." (via @gnat) Especially true when people like Michael Nygard say things like "I prefer my servers to have a minimum of 4 NICs, preferably 6".

Indexing Documents Before we can query the index we have to make sure that the documents are indexed properly and automatically. It doesn't matter if you put the following code into a new app or an existing app. You only have to make sure, that it lives in a file, which is loaded by Django when the process starts, resonable places would be the __init__.py or the models.py file (or any file imported in those of course) in any app. The following code listing is interrupted by short explanaitions but should be saved into one file: import os from dj

Finding the perfect IDE for Python isn’t an easy feat. There are a great many to chose from, but even though some of them offer really nifty features, I can’t help myself but feel attracted to VIM anyway. I feel that no IDE accomplishes the task of giving the comfort of complete power over the code - something is always missing out. This is why I always come back to using IDLE and VIM. Those two seem to be best companions when doing some quick and agile hacking - but when it comes to managing bigger and longer term projects, this combo needs some tweaking. But when it’s done, VIM will be a powerful IDE for Python - including code completion(with pydoc display), graphical debugging, task-management and a project view.

Excellent guide to get VIM going as a good IDE, especially for Python.

Google Tech Talk April 24, 2009 ABSTRACT Presented by Joel Spolsky Until recently, searching for help on highly technical programming problems has been a mess. A lot of what the search engines found was old discussions in forums, where you have a lot of wrong answers and out-of-date answers that you have to sift through yourself. You also found a lot of answers at sites that were hidden behind a pay wall, which uncloaked themselves for Google and then demanded membership fees to see the answers. StackOverflow.com is a programmer's Q&A site that launched last September to address these problems. It incorporates more modern ideas about community such as voting and public editing, and even a few ideas from game design, to create a much more successful way to get help with programming problems. In a few short months, it has grown to 14 million page views a month and reaches 3 million unique programmers every month.

ke a look at how we can use the Site Analysis tool to quickly

SEO (search engine optimization) is one of the important considerations that any Internet web-site needs to design with in mind. A non-trivial percentage of Internet traffic to sites is driven by search engines, and good SEO techniques can help increase site traffic even further. Likewise, small mistakes can significantly impact the search relevance of your site’s content and cause you to miss out on the traffic that you should be receiving. Some of these mistakes include: multiple URLs on a site leading to the same content, broken links from a page, poorly chosen titles, descriptions, and keywords, large amounts of viewstate, invalid markup, etc. These mistakes are often easy to fix - the challenge is how to discover and pinpoint them within a site.

I figured that I could take notes to help students follow the lectures while clarifying any confusing points that were raised during discussion. It would also help me avoid the embarrassment of forgetting something mentioned during a lecture and having students explain it to me during office hours:). I decided to take notes in plain text, mostly out of laziness. This turned out to be a challenge for drawing things like query plans, but forced me to distill explanations into a conversational tone that provided an alternative to traditional diagrams. Some students in the class told me that they benefited from and enjoyed the notes, and so I decided to open them up for reuse

Why do we need an analogy? We know what we do. We program computers, with all that entails. And we know what that means, because we do it.

They don't want to know everything about it, but they want to know enough to be able to predict the behavior of software development, at least approximately.

t replace a programmer with just any other programmer and get similar results. It also suggests that you should evaluate what kind of project you're creating when you decide who your team should be, and how it will run. The creation of mysteries and young adult fiction and so-called "bodice rippers" and the vast sea of nonfiction books all have their own particular structure and constraints (you'd be surprised at how rigid and controlling publishers are about these things, as if they are manufacturing some kind of basic commodity -- "the murder has to happen in the first 10 pages" etc.). None of these are the mass-market bestsellers ("killer apps") that are sold by the author's voice and style (few of which I find readable). The mass-market bestsellers usually don't coincide with the great writers, since most people don't have the patience to read these meta-craftsmen, just as most programmers don't read the source code for compilers.

For some scripting languages, like BeanShell, it's possible to access Android's Java API directly. To simplify things, ASE provides the AndroidFacade class. For other languages, like Python and Lua, the API is made available via JSON RPC calls to a proxy. Naturally this means that only the part of the API which has been wrapped by the AndroidFacade and AndroidProxy are available to cross-compiled interpreters like Python and Lua. Thankfully, both AndroidFacade and AndroidProxy are simple to extend.

"list of recommendations for using cryptography which, if followed, will make sure you get things right in the vast majority of situations"

Thanks to my background as FreeBSD Security Officer, as a cryptographic researcher, and as the author of the Tarsnap secure online backup system, I am frequently asked for advice on using cryptography as a component in secure systems. While some people argue that you should never use cryptographic primitives directly and that trying to teach people cryptography just makes them more likely to shoot themselves in their proverbial feet, I come from a proud academic background and am sufficiently optimistic about humankind that I think it's a good idea to spread some knowledge around. In light of this, I've put together a list of "Cryptographically Right Answers" -- which is to say, a list of recommendations for using cryptography which, if followed, will make sure you get things right in the vast majority of situations.

The hard truth is that the buck of development should stop with designers. For optimum efficiency, designers should not only be concerned with painting the bigger picture but also building it! In this article, I'd like to share with you some reasons why designers should learn how to code.

The first one is to use an in-memory data store, and communicate using the memcached protocol. This is, of course, *exactly* comparable to Memcached — behaviorally indistinguishable! — and it does worse. The second option is to do that, except switch to an on-disk data store. It’s pretty ridiculous that that’s still the same speed — communication overhead is completely dominating the time. Fortunately, Tyrant comes with a binary protocol. Using that substantially improves performance past Memcached levels, though less than a direct in-process database. Yes, communication across processes incurs overhead. No news here, I guess.

It’s incredibly flexible; it was very easy to run it in several different configurations. The first one is to use an in-memory data store, and communicate using the memcached protocol.

jQuery, since 1.2.2, has had an API for “special events”. These events are special because they have the ability to do some extra work for specific events and even the option to bypass some of the internal jQuery event system. With these special events you can create custom events that require some setup work or you can completely overwrite the behavior of native events.

In this article, I’ll try to summarize both - theoretical and practical aspects of these wonderful Javascript constructs; the good, bad and ugly parts of them.

Problem. You are interested in how the Google Chrome 3.0 Dev, Firefox 3.5 RC, Safari 4.0 for Windows, and Opera 10b web browsers manage memory on the Windows Vista operating system over moderate usage, such as with 150 top web sites. These numbers can be measured but there are complexities involved in measuring memory. Solution. Here we look at a program that simulates a user visiting the top 150 web sites from Alexa from the command line, with visits occurring at short but varying intervals in many tabs.

If you want to make a personal decision that only you can make like whether or not you should start a business, try putting into writing a list of arguments for and against the idea. If that fails, consider divination. Suppose you have studied the idea from all angles, have done all your homework, and worked out all the consequences and pros and cons in your mind, and yet still remain indecisive. You now must follow your heart and tell your brain to shut up. The multitude of available divination techniques are very useful for determining your own semi-conscious desires, as they each present a complete ambiguous and random pattern that your own subconscious will assign meaning to.

I don’t know. Sometimes I feel like some of these folks try too hard to soft-sell the excellent way presented by test-driven development (TDD) and pair programming (PP). A lot of alleged agilists make this argument: you see, by PP’ing and TDDing, you will greatly increase your quality, so even though your productivity goes down, you get the coolest glow by knowing in your heart of hearts that you are a good citizen of the coding world. I call bullshit. Not only is it not true that you can trade internal quality for more features, it’s actually the exact opposite case: the more productivity you seek, the higher you should raise your standard of internal quality. That’s right, that’s what GeePaw says. If you want more production, look first to raising your internal quality. So, how can such things be? 1. Because internal quality and external quality are not the same things. 2. Because the biggest single determinant in today’s production is the quality of yesterday’s product

The best part about Webhooks is that most of us are already familiar with them: callbacks over HTTP. Pioneered by PayPal and Subversion as a way to send real-time notifications to the client, they have found their way into many dozens of products we all use every day. Need pre or post commit hooks for your SVN or Git repository? Both GitHub and SVN support HTTP callbacks. Need a payment alert from PayPal, or an alert when a wiki page is modified? There are webhooks for that too. This simple mechanism allows us to build web services that work together via a simple and ubiquitous protocol we can all understand: HTTP!

"We offer this spec in hopes that it fills a need or at least advances the state of the discussion in the pubsub space. Polling sucks.

"Do you have five minutes? No. Why? Because I’m lying. It would take much longer than five minutes. That’s the eternal optimism of programmers."

Very good critique of the notion that a web app which at its core may just be an interface to a couple of database tables is a trivial thing that can be banged out in a few days. While it's possible to put up a basic front-end that quickly, all the extras that go on top of that to make a real, usable application take much, much longer. User interface matters.

No, not SHARED lessons, I mean SHARD lessons. I have to admit that until about a year ago I didn't really know the term shards in relation to databases. Now don't confuse that with not understanding how databases can be horizontally scaled.

Regardless of what you call it, there are some interesting challenges that are introduced. The well known challenges of consistency are discussed ad nauseam, even by me, so I'm not going there with this article. But besides that, there are some other lessons to learn when applying the pattern to your data.

Namespaces are one of the most significant changes in PHP 5.3. They will be familiar to C# and Java developers, and they are likely to change the structure of PHP applications for the better. Why Do We Need Namespaces? As the size of your PHP code library increases, there is increased risk of accidentally re-defining a function or class name that has been declared before. The problem is exacerbated when you attempt to add third-party components or plugins; what if two or more code sets implement a ‘Database’ or ‘User’ class? Until now, the only solution has been long class/function names. For example, WordPress prefixes every name with ‘WP_’. The Zend Framework uses a highly descriptive naming convention that results in long-winded class names such as Zend_Search_Lucene_Analysis_Analyzer_Common_Text_CaseInsensitive.

Stack Overflow Architecture | High Scalability

Stack Overflow is a much loved programmer question and answer site written by two guys nobody has ever heard of before. Well, not exactly. The site was created by top programmer and blog stars Jeff Atwood and Joel Spolsky. In that sense Stack Overflow is like a celebrity owned restaurant, only it should be around for a while. Joel estimates 1/3 of all the programmers in the world have used the site so they must be serving up something good.

The following pages should give you answers regarding Palm® webOS™ platform development that you could not find anywhere else on this site. Just jump into the section(s) that interest you.

asm_new = disassemble(update) asm_new_adjusted = adjust(asm_new, asm_old) asm_diff = bsdiff(asm_old, asm_new_adjusted) transmit asm_diff client:

We want smaller updates because it narrows the window of vulnerability. If the update is a tenth of the size, we can push ten times as many per unit of bandwidth. We have enough users that this means more users will be protected earlier. A secondary benefit is that a smaller update will work better for users who don't have great connectivity.

Interesting thoughts on why simple meetings blow the entire day's schedule for a programmer (via Justin Miller)

When you're operating on the maker's schedule, meetings are a disaster. A single meeting can blow a whole afternoon, by breaking it into two pieces each too small to do anything hard in.

If you can't actually avoid meetings, then at least try to schedule them so you can maximise your productivity. Rings true...

A Squeak fork

a fork from the Squeak open-source Smalltalk. We decided to start Pharo because as active Squeakers, and responsible for Squeak 3.9, we felt the need to reconsider choices made. We want to create a better Smalltalk and be free to enhance it without fear of backwards compatibility. Deciding to start Pharo was not easy because we invested a lot in Squeak (some of us wrote several books on Squeak and in particular Squeak By Example http://www.squeakbyexample.org/ ) and we like the Squeak community, but this is really important for us to open a new space. We want Pharo to be an excellent Smalltalk concerned with software engineering practices. We also want Pharo to be agile and be able to evolve. We hope you will like it and help make it better.

"One of the (many) unfortunate side effects of choosing a career in software development is that, over time, you learn to hate software. I mean really hate it. With a passion. Take the angriest user you've ever met, multiply that by a thousand, and you still haven't come close to how we programmers feel about software. Nobody hates software more than software developers. Even now, writing about the stuff is making me physically angry. "

“We don’t have 200k RSS subscribers because of my deliciously swirly hair” - a central question (asked also during the Q/A session): how on the earth did Basecamp and other 37signals products become so popular? All of a sudden, they emerged from nowhere! As David points out, it was not that ‘out of the blue’ as it looks like. When they started with Basecamp, they already had 2000 subscribers on their blog, Signal vs Noise, so they built a channel which through they could advertise themselves. This advice meshes with one of my favorite points from Getting Real which goes something like “Just start doing something”. Really. Start blogging. Creating/contributing to open source software. Get on twitter. Let your voice be heard! You probably won’t have thousands of listeners right away, that’s OK - it takes time. But you can start today!

I wish there wasn't continued reinforcement of gender roles.

I am aware of my surroundings and chose to be here, so...

As everyone knows, the more dependencies you have in a system, the harder maintaining that system is. Javascript is no exception- and orchestrating actions across complex user interfaces can be a nightmare if not done properly. Luckily, there’s a great pattern for orchestrating complex interaction in a disconnected way. No, it’s not the Observer pattern. It’s a take on the Observer pattern called Event Pooling which is a piece of cake with jQuery’s bind and trigger functions. For the get to the code folks, here’s an example of using jQuery’s bind and trigger for event pooling.

For our first hack day, I put together a list of “tools for non-developers”—sites, services and software that could be used for hacking without programming knowledge as a pre-requisite.

Not too long ago, I wrote about loading JavaScript without blocking by creating a dynamic <script> tag. When <script> tags are in the flow of an HTML document, the browser must stop rendering and wait for the script file to download and execute before continuing (example). Creating a new <script> tag via JavaScript avoids this issue because it’s out of the flow of the document, so the script file is downloaded and executed without waiting. The result: dynamically loading JavaScript files allows your page to render faster and therefore improve perceived performance.

In this article, we'll take a behind-the-scenes look at the design and development of btrfs on many levels - technical, political, personal - and trace it from its origins at a workshop to its current position as Linus's root file system. Knowing the background and motivation for each step will help you understand why btrfs was started, how it works, and where it's going in the future. By the end, you should be able to hand-wave your way through a description of btrfs's on-disk format.

btrfs is a b-tree based fs that is cow friendly (i.e. by removing sibling links you don't have to copy whole tree on block update). Support snapshots, checksums etc. Implementation comes out of Oracle, has some commonalities with zfs.

HTML5 is getting a lot of love lately. With the arrival of FireFox 3.5, Safari 4 and the new betas of Google Chrome and Opera, browsers support some great new features including canvas and the new audio/video tags. Most interesting: modern mobile devices like the iPhone or Android-based phones also support new standards in favor of Flash. The future looks bright for HTML5. Time for us to play with this technology. We’ve created a litttle experiment which loads 100 tweets related to HTML5 and displays them using a javascript-based particle engine. Each particle represents a tweet – click on one of them and it’ll appear on the screen. The original particle engine was ported from a Flex/AS3 project that we’ve created to javascript. We’re using processing.js for particle rendering on canvas which is a very useful graphics library created by John Resig. The music will only be played if the browser supports the audio tag. To detect if the audio or canvas feature is present we use the aweso

Useful, quick and easy walkthrough of writing a Python/Django app which interfaces with Twitter, and deploying it to Google AppEngine.

Twitter’s robust REST API enables building of good applications that leverage its increasingly large and real-time data. Google’s cloud system App Engine not only provides a scalable platform for deploying applications, but also proves to be economically viable because of its pay per resource usage model and a large free quota. Little wonder then, there are increasingly large number of twitter apps being deployed on App Engine. In this post, I am going to examine how to create a simple application based on twitter’s REST API and deploy it on Google App Engine. A deployed version can be found on Twitter-Follow. The specification is simple. It finds if a twitter user is following another twitter user, given their user names. The application is developed using django and deployed on Appengine using the app engine patch project. The code is open sourced with GPL v3 and can be checked out from Google Code. Lets get started building this application.

Elliotte Rusty Harold's perspective on six reasons that he believes pair programming succeeds: 1) Continuous code review, 2) Fewer blockages, 3) Masking distractions, 4) Guaranteed focus, 5) Multiple points of view, and 6) Reduced training cost and time.

Pair programming is like magic in more ways than one. It dramatically improves programmer productivity and reduces bug count, and yet it does so through a technique that’s completely counter-intuitive.

Clojure is surrounded by hype these days. The word on the streets is that Clojure is the Next Big Thing. It has access to the largest library of code and it proposes a nice solution the to the concurrency problem. Lots more has been said... But I haven't seen a lot of code. So I set out to make a small but meaningful program in Clojure to get a sense of it's potential. I give Clojure two thumbs up, and I think you'll do too.

ParseKit Home Tokenization Grammars iPhone Source Code Header Docs ParseKit Documentation ParseKit ParseKit is a Mac OS X Framework written by Todd Ditchendorf in Objective-C 2.0 and released under the MIT Open Source License. ParseKit is suitable for use on Mac OS X Leopard or iPhone OS. The framework is an Objective-C implementation of the tools described in "Building Parsers with Java" by Steven John Metsker. ParseKit includes additional features beyond the designs from the book and also some changes to match common Cocoa/Objective-C conventions. These changes are relatively superficial, however, and Metsker's book is the best documentation available for ParseKit. The ParseKit Framework offers 3 basic services of general interest to Cocoa developers: String Tokenization via the Objective-C PKTokenizer and PKToken classes. High-Level Language Parsing via Objective-C - An Objective-C parser-building API (the PKParser class and sublcasses). Objective-C Parser Generation via Grammars

While parsing, the parser will provide callbacks to your Objective-C code.

Once a bit player, JavaScript increasingly takes center stage. Its footprint—the space it takes up on our servers and in our development schedules—continues to grow. So how can we make our JavaScript more reusable and easier to maintain? Perhaps MVC will offer some clues. While MVC is a familiar term to those in back-end application development—using frameworks such as Struts, Ruby on Rails, and CakePHP—MVC’s origin in user interface development lends itself to structuring client-side applications. Let’s examine what MVC is, see how we can use it to rework an example project, and consider some existing MVC frameworks.

For static content, we may want the response cached. But for dynamic content, which can change in a second's time, caching AJAX becomes a bug, right? It should be noted that Internet Explorer always caches AJAX calls, while other browsers behave differently. So we'd better tell the browser explicitly whether or not AJAX should be cached. With jQuery, we can accomplish this simply by typing:

Regular expressions (”regex’s” for short) are sets of symbols and syntactic elements used to match patterns of text and they are pretty powerful. Regular expressions have been around for a very long time (in computer industry scale) and was first introduced as part of the powerful UNIX search tool grep.

Code is serving as a medium between words, emotions, and images; between poetry and painting. Gluing computers with our emotions and aesthetic experiences, it is both a software innovation and an interactive art experiment. Also, it is the first of that kind that is also a free open-source project – not just a closed academic research experiment – so that the whole community can benefit from it. The name ‘Synesketch’ is a portmanteau of ‘synesthesia’ and ‘sketch’ – where ‘sketch’ does not only refer to drawings, but also to the Processing artworks called ‘sketches’.

I'm OK; The Bull Is Dead June 21, 2004 (Computerworld) Early in my career, when I worked as an engineer, my boss had a process by which the engineering team was expected to report project status. He insisted that we use the following steps, in the specified order: 1. Punch line: The facts; no adjectives, adverbs or modifiers. "Milestone 4 wasn't hit on time, and we didn't start Task 8 as planned." Or, "Received charter approval as planned." 2. Current status: How the punch-line statement affects the project. "Because of the missed milestone, the critical path has been delayed five days." 3. Next steps: The solution, if any. "I will be able to make up three days during the next two weeks but will still be behind by two days." 4. Explanation: The reason behind the punch line. "Two of the five days' delay is due to late discovery of a hardware interface problem, and the remaining three days' delay is due to being called to help the customer support staff for a production problem."

Unfortunately I'm short on time at the moment (trying to launch a project this week) but I have to say, at least, a few words about the hacker and artist _why. At this moment, _why's online presence appears to be no more. All of his sites and code are gone. This includes, and is not limited to: * http://twitter.com/_why * http://github.com/why * http://whytheluckystiff.net/ * http://poignantguide.net/ * http://hackety.org/ * http://shoooes.net/ * http://hacketyhack.net/ * http://tryruby.hobix.com/ Two conjectures are common at the moment: His account(s) were hacked and sites taken down or he simply decided to delete his online presence. I personally believe that he did this deliberately and with some amount of forethought.

One of the things that's made _why unique amongst programmers is that he has worked in virtual anonymity. Some people knew his name but it was never a focus of his online persona (and, at least, never actively associated with him as a person - I've seen sites that purport to identify him, but they're generally incorrect, and fringe, at best). Even live, giving talks or performing music, he still went by his pseudonym.

Even live, giving talks or performing music, he still went by his pseudonym. Reading through the original discovery thread you can see a full range of emotion regarding his disappearance; Anger, confusion, and sadness. Personally, I feel a mixture of joy and amazement. _why, the code he's written, the persona he projected, and the art he produced has been a long-time admiration of mine. Some only see _why's code or writing (Why's Poignant Guide to Ruby, for example - which can still be purchased on Lulu). I tend to see _why more as an artist. He used a wide variety of mediums for his exploration: Written word, drawings, code, and even music.

Why the Lucky Stiff has disappeared. I share John Resig's admiration for his whimsical approach and his pseudonymity, but find it hard to identify with deleting all your work.

"I've seen a few people ask why he opted to remove his code - why didn't he take his work seriously? (Especially since others have grown to depend upon it.) Looking at the cumulative work and art of _why it should become painfully obvious: The online presence of _why, and all the code, writing, music, and drawings that've been produced are a mere transitory portion of one person's life. He was constantly moving from project to project, blog to blog. Now he's truly moved on and we should feel joy in having gotten to know him, and his art, over the past couple years."

At this moment, _why's online presence appears to be no more. All of his sites and code are gone. This includes, and is not limited to: ...

# Fulfill Your Ambitions with Open Source by Richard Monson-Haefel # Comment Only What the Code Cannot Say by Kevlin Henney

Monk is a glue framework for web development in Ruby. It’s truly modular by relying on the best tool for each job. It’s also pretty fast thanks to Rack and Sinatra.

Sinatra is a tiny and flexible tool. It can be used to write super simple web applications like an API or a fully-fledged, highly interactive website. As you develop more applications using Sinatra, you will start to find some patterns: You apply a similar structure to all of your projects (where to put your routes, whether to use classic or modular style, etc.) You also find some other common bits you need to set up a logger, configure reloading on development mode, and more. You need to hook up your persistence layer of choice. Wiring in your desired testing suite. It’s easy to see how time-consuming this can be when you want to start a new project with the minimum amount of work. That’s why we wrote a tool that could enable us to get started on a new project in no time. The result is a command line tool that lets you create a new project out of an existing skeleton. The default skeleton we ship does all the work for you, and you can just dive into your code.

Free course/lecture notes on optimization algorithms: genetic algorithms, simulated annealing, particle swarm optimization

"What is a Metaheuristic? A common but unfortunate name for any stochastic optimization algorithm intended to be the last resort before giving up and using random or brute-force search. Such algorithms are used for problems where you don't know how to find a good solution, but if shown a candidate solution, you can give it a grade. The algorithmic family includes genetic algorithms, hill-climbing, simulated annealing, ant colony optimization, particle swarm optimization, and so on. "

This is an open set of lecture notes on metaheuristics algorithms, intended for undergraduate students, practitioners, programmers, and other non-experts. It was developed as a series of lecture notes for an undergraduate course I taught at GMU. The chapters are designed to be printable separately if necessary. As it's lecture notes, the topics are short and light on examples and theory.

That is, PHP suffers from most of the same problems as CGI, but to a lesser extent.

Joe Gregorio suggested Protocol Buffers as a efficient to implement inter-operation for applications built with different languages. Look in the comments for "Common Lisp Users" and laugh out loud. It's really true. Man, we, those who program as a business, are really screwed big time with mass concurrency problems.

Why do you hope you're using Python in 2020? I've been a Ruby developer for the last 3 years, but I don't hope I'm still using Ruby in 10 years. I hope something has come along by then and swept away my expectations of what programming can be like and replaced it with something that feels wholly new, like has happened for me multiple times. I'd feel stagnant and dependent if I was using one primary language for 10 years.

Polling architectures, as pervasive as they are today, did not come about due to their efficiency. Whether you are maintaining a popular endpoint (Twitter), or trying to get near real-time news (RSS), neither side benefits from this architecture. Over the years we've built a number of crutches in the form of Cache headers, ETags, accelerators, but none have fundamentally solved the problem - because the client remains 'dumb' the burden is still always on the server. For that reason, it's worth paying attention to some of the technologies which are seeking to reverse this trend: ReverseHTTP & WebSockets.

Observation: Co-routines are to state machines what recursion is to stacks When you have to traverse some sort of a nested data structure (say, a binary tree), one approach is to create a stack that remembers where in the tree you are. Another, much more elegant approach, is to write the function recursively. A recursive function employs the machine stack used to implicitly implement function calls - you get the benefits of the stack without paying the cost of reduced readability.

I just foolishly got caught in a You-Tube discussion on Java vs C performance. Foolish because You-Tube comments are a lousy way to present anything and because it's hard to keep the level of discourse scholarly. And foolish especially for me because I've had this discussion so many times and it always comes out the same way... so here's my attempt at distilling my arguments into something I can point people the *next* time I get caught in this silly discussion. Is Java faster than C/C++? The short answer is: it depends.

A function accepts input and produces an output. Suppose we have a "chocolate-covering" function that produces the following outputs for the corresponding inputs: peanuts -> chocolate-covered peanuts rasins -> chocolate-covered rasins ants -> chocolate-covered ants We can use Lambda-calculus to describe such a function: Lx.chocolate-covered x This is called a lambda-expression. (Here the "L" is supposed to be a lowercase Greek "lambda" character). If we want to apply the function to an argument, we use the following syntax: Functions can also be the result of applying a lambda-expression, as with this "covering function maker": Ly.Lx.y-covered x We can use this to create a caramel-covering function: (Ly.Lx.y-covered x)caramel -> Lx.caramel-covered x (Lx.caramel-covered x)peanuts -> caramel-covered peanuts Functions can also be the inputs to other functions, as with this "apply-to-ants" function: Lf.(f)ants

Nice round up of lightweight frameworks for PHP

I want to share with you the concept that you can think about version control not as a neccesary inconvenience that you need to put up with in order to collaborate, but rather as a powerful framework for managing your work seperately in contexts, for being able to switch and merge between those contexts quickly and easily, for being able to make decisions late and craft your work without having to pre-plan everything all the time. Git makes all of these things easy and prioritizes them and should change the way you think about how to approach a problem in any of your projects and version control itself.

"Clamato is a Smalltalk dialect that is designed to operate within the JavaScript runtime. "

Clamato is a Smalltalk dialect that is designed to operate within the JavaScript runtime.

Clamato is a Smalltalk dialect that is designed to operate within the JavaScript runtime. Clamato is self-hosting, in that it can compile itself to efficient JavaScript, entirely within the web browser. It uses a parser library based on Lukas Renggli’s PetitParser. Smalltalk constructs (eg: temps, instance variables, message sends, blocks) generally map one-to-one to their JavaScript equivalents (respectively: local variables, object properties, method calls, functions). There are several departures from Smalltalk’s syntax and semantics. The most notable of these are: no explicit returns, 0-based indexing, no metaclass hierarchy, special syntax for instance variables. Clamato includes an (incomplete) interface to the JQuery JavaScript library, along with a Seaside-like HTML builder. Cæsar is a system browser built on all of the above. Like Clamato, it departs in a few notable ways from traditional Smalltalk browsers, but retains their spirit.

Do you suspect a programmer may have put together the terrible user interface on that “enterprise” software you’re forced to use every day? There are some give-away indicators. Look out for them in your software, hunt down the developer and force them to read a book about user interface design. If you’re suitably senior, force them to a) improve it, or even better b) get someone with real UI experience to fix it.

Mejorar la velocidad de JSON

When you’re working with JSON, performance and security are often opposing, yet equally important concerns. One of these areas of contention is handling the JSON strings returned by a server. Most JavaScript libraries do a great job of abstracting away the details, but the underlying process has long been a frustrating exercise in compromise. On one hand, eval() is the fastest widely available method, but it is not safe. On the other hand, textual JSON parsers written in JavaScript may be much safer, but are dramatically slower. In client-side situations, where milliseconds count, such a large performance overhead is typically too prohibitive to accept. Recently, an exciting new alternative has emerged: browser-native JSON parsing. Integrating JSON parsing as part of the browser’s implementation of JavaScript allows for using the more secure parsing method, and even provides performance faster than eval() offers.

Recently, an exciting new alternative has emerged: browser-native JSON parsing. Integrating JSON parsing as part of the browser’s implementation of JavaScript allows for using the more secure parsing method, and even provides performance faster than eval() offers. To take advantage of that, this post will show you how to detect whether or not a browser supports native JSON parsing, and how to force jQuery to use browser-native parsing in its $.ajax calls when it is available.

He then introduces the Spring Framework and explains how it leverages the concepts of Spring, including dependency injection. Finally, Steven guides you through a programming tutorial that demonstrates the core features of Spring MVC in an easy-to-follow, hands-on format.

In many languages (all the good ones, if you ask me),  lexical scoping is supported. Lexical scoping basically allows you to access local variables in a parent function. If a function is defined within another function, it can access its own local variables as well as those of the function it was defined within. Time for another example.function drinkBeer() { var beer = "Big Daddy IPA"; function pour() { var glass = "Pint Glass"; return "Poured " + beer + " into a " + glass; } function drink() { beer = null; return "Beer is all gone"; } pour(); drink(); } drinkBeer();This works just fine. drinkBeer cannot access glass, but pour and drink can access beer. //// /*<!--<a href="http://justin.harmonize.fm/index.php/2009/09/an-introduction-to-javascripts-this/">Caffeinated Simpleton » Blog Archive » An Introduction to JavaScript’s “this”</a>-->*/

People often ask how can I justify two people when one will do. Will this not, just double my cost? To answer this question I think it is important to discuss what pair-programing is not.

At the simplest level pairing is helping people one-on-one, not through emails, let me show you behind a keyboard, instead of telling you in abstract. The amount of pairing and keeping each other on track depends on many things, but you will find that more you pair the more you will learn from each other and the better the code becomes.

Whether you are a CSS expert or newbie, a programmer or a designer, you need abstractions to quickly and effectively build and maintain the design of your website.

I’ve seen a number of comments on blogs and twitter that amount to “You don’t need a new stylesheet syntax, CSS is simple and you’re a moron if you can’t do it.” I agree, CSS is simple. You assign style primitives to elements and some of those primitives cascade down to the elements contained within. I get it. It’s simple to understand. But CSS is not simple to use or maintain. It’s time for stylesheets to evolve so that we can take web design to the next level. Over the past few years the development of JavaScript frameworks have brought sanity to coding against the DOM – optimizing common coding tasks through the creation of abstractions than insulate us from the nitty-gritty details and providing a common platform for third-party libraries to rely on. As a result, it’s a very nice time to be a front-end programmer. It’s been a couple of years since I’ve bitched about DOM incompatibilities – long enough to almost forget how much work it used to be. It’s also a very nice time to be a

The “Translator” class can be used to translate text. It provides a function called “translate” that takes three arguments - “message“, “lang_from” and “lang_to“. It returns the translated text as a Unicode string. Don’t forget to encode it to the right encoding before outputting, otherwise you’ll get errors such as “UnicodeEncodeError: ‘latin-1′ codec can’t encode characters in position 0-3: ordinal not in range(256)”

For those not familiar with the history of this discussion, the term "parse" here is being used in its strict sense to mean static parsing -- taking a piece of code and determining its structure without executing it. In that strict sense the Perl program does not parse Perl. As Jeffrey pointed out it means that you can't reliably parse perl code without executing it. This means that things like static code analysis, code transformation and syntax hilighting will never be reliable. This is a drawback indeed, but on the other hand it means that modules can extend Perl's syntax, and that other nifty stuff can be accomplished. So I understand this node as a proof of a property that is seldom fully understood.

[ UPDATE 14 Aug 2009: A series of three articles in The Perl Review, now available online, expands on this node. In that series, the proof is carefully laid out in three different versions, and is much more thoroughly explained. ]

We present a system that composes a realistic picture from a simple freehand sketch annotated with text labels. The composed picture is generated by seamlessly stitching several photographs in agreement with the sketch and text labels; these are found by searching the Internet. Although online image search generates many inappropriate results, our system is able to automatically select suitable photographs to generate a high quality composition, using a filtering scheme to exclude undesirable images. We also provide a novel image blending algorithm to allow seamless image composition. Each blending result is given a numeric score, allowing us to find an optimal combination of discovered images. Experimental results show the method is very successful; we also evaluate our system using the results from two user studies.

19 Tips for Recruiting Great Developers

"By doing the compilation step, we allow developers to create applications using their Flash skills and their knowledge of ActionScript 3. In the process, we also expose the APIs that developers are familiar with so they can not only use the ActionScript language but follow the customary app-building model. When you build your application for the iPhone, there is no interpreted code and no runtime in your final binary. Your application is truly a native iPhone app." Nice, could this pattern be used to deploy AS3 projects to other environments.

Adobe now makes it possible to create applications for the Apple iPhone using the Adobe Flash Platform. You heard right: We're really excited to bring this new capability to Flash designers and developers—the ability to target the iPhone with ActionScript 3 projects.

"Graphs are ubiquitous. Social or P2P networks, thesauri, route planning systems, recommendation systems, collaborative filtering, even the World Wide Web itself is ultimately a graph!

In this short article, we’re going to see how we can store a graph in a DBMS.

A really neat Google App that lets you enter a code snippet in js, PHP or Python, and then run it if you so desire with GET and POST vars; if that's not enough, you can also fire off an HTTP POST to a third party server.

Client client communication with shared objects and flash js communication

javascriptからsharedobjectが操作できるらしい？後で試してみよう！

Lately I was discussing about programming a flash-based multiuser game using sharedObjects. I’m not so fond of Flash so I thought: Flash can communicate with Javascript. So why not implement the game in Javascript and do only the multiplayer-communication in flash? I created jsSO to allow the clients to push data to the server and notify other clients immediately about changes. So this library allows programming of realtime games, chats etc.

xCSS, un nuevo framework CSS orientado a objetos.

First CSS framework that allows you to work object-oriented and keeps your workflow as “DRY” as possible

xCSS extends CSS and gives you the ability to cut down the development time by having a better overview, using variables, re-using your models and many other features.

Why a CSS framework? xCSS bases on CSS and empowers a straightforward and object-oriented workflow when developing complex style cascades. Using xCSS means a dramatic cut down to your development time by: having a intuitive overview of the overall CSS structure, using variables, re-using existing style cascades and many other handy features. But, most frameworks are bulky and inflexible, aren't they? Not xCSS! It's lightweight and seamlessly integrates into any existing workflow. Aside from that the CSS overhead is getting reduced while your (X)HTML attributes remain semantic.

Cet article explique ce qu'est AMQP et comment l'utiliser en Ruby.

The flexibility of the message and the exchange model is what makes AMQP such a powerful tool. Whenever a publisher generates a message, he can mark it as 'persistent' which will guarantee delivery through the broker - if there is an attached queue, it will accumulate messages until the consumer requests them. However, if you're streaming transient data (access logs, for example), you can also disable message persistence and not worry about overwhelming your broker. That's how you achieve 'exactly-once' vs 'at least once' semantics.

60 Resources for the Frugal Web Developer - http://webjackalope.com/frugal-web-developer/

Photo by s2photo With the economy reeling and VC’s spending less and less on startups, developers have had to adapt how they create sites. Because of the world’s economic state, we’ve had to change how we develop. Some may see this shift as a grim prospect. Change is hard, and change is essential to staying alive in these conditions. However, if you can cut expenses in your development process without cutting quality by using free methods and tools, then you may be able to develop without using any extra money.

collection of rack middleware

If you've worked with Web apps using Ruby, you might know of Rack, an interface that sits between Ruby applications and HTTP-speaking Web servers. All of the major Ruby frameworks and server setups use it now, including Rails. Middleware (in Rack) is code that manipulates data going back and forth between your Ruby apps and the HTTP server. You can use middleware to intercept requests, change data in mid-flow, etc. Ryan Bates has a great screencast tutorial if you're new to the concept and want to build your own.

Looks like a pretty clean interface.

"Relational database management systems (DBMSs) have been remarkably successful in capturing the DBMS marketplace. To a first approximation they are “the only game in town,” and the major vendors (IBM, Oracle, and Microsoft) enjoy an overwhelming market share. They are selling “one size fits all”; i.e., a single relational engine appropriate for all DBMS needs. Moreover, the code line from all of the major vendors is quite elderly, in all cases dating from the 1980s. Hence, the major vendors sell software that is a quarter century old, and has been extended and morphed to meet today’s needs. In my opinion, these legacy systems are at the end of their useful life. They deserve to be sent to the “home for tired software.” Here’s why."

I started investigating how I might write native iPhone apps from a scripting language. Lua was on my radar already. It’s compact, expressive, fast enough, and was designed to be embedded. Took only about 20 minutes to get the Lua interpreter running on the iPhone. The real work was to bridge Lua and all the Objective-C/CocoaTouch classes. The bridge had to work in two directions: it would need to be able to create CocoaTouch objects and also be able to respond to callbacks as part of the familiar delegate/protocol model.

The purpose of this project is to provide an emulation of the on-board Apollo guidance computers, along with some ancillary items needed to make the emulation do something interesting. "AGC" stands for Apollo Guidance Computer. The AGC was the principal on-board computer for NASA's Apollo missions, including all of the lunar landings. Both the Command Module (CM) and the Lunar Module (LM) had AGCs, so two AGCs were used on most of the Apollo missions, but with differing software. The computer and its software were developed at MIT's Instrumentation Laboratory, also known as Draper Labs.

test iphone distribution app before submitting

changing the code signing to install in itunes

If you’ve submitted an application to the App Store, you know that sinking feeling of not being able to test your final build. The binary that gets signed with the “App Store” distribution mechanism cannot be run on your test devices: you can’t be sure that the final bits you send to Apple are complete. But there’s a simple way around this problem and it’s called codesign. The same application we used for our pre-Ad Hoc beta testing can also be used for a final test on your App Store submissions.

Since 2005, VMware and Xen have gradually reduced the performance overheads of virtualization, aided by the Moore’s law doubling in transistor count, which inexorably shrinks overheads over time. AMD’s Rapid Virtualization Indexing (RVI – 2007) and Intel’s Extended Page Tables (EPT – 2009) substantially improved performance for a class of recalcitrant workloads by offloading the mapping of machine-level pages to Guest OS “physical” memory pages, from software to silicon. In the case of operations that stress the MMU—like an Apache compile with lots of short lived processes and intensive memory access—performance doubled with RVI/EPT. (Xen showed similar challenges prior to RVI/EPT on compilation benchmarks.)

Underscore provides 44-odd functions that support both the usual functional suspects: map, select, invoke — as well as more specialized helpers: function binding, javascript templating, deep equality testing, and so on.

This post isn't so much about the usefulness of mailing lists as a discussion medium, it's the complete failure of Google Groups as an adequate purveyor of public discussion software. For the jQuery project we're already in the process of moving the full discussion area to a forum that we control. We should have it set up, and everything moved over, within the next month or two. There is one area in which Google Groups continues to shine: Private, or restricted, mailing list discussions. However any attempts at using it for a public discussion medium are completely futile. The primary problem with Google Groups boils down to a systemic failure to contain and manage spam. Only a bottom-up overhaul of the Google Groups system would be able to fix the problems that every Google Group faces.

Why Haskell is beyond ready for Prime Time

Here’s a concrete example: I’ve got a list of numbers, and I want to split it up into two lists — one consisting of the evens, one consisting of the odds. This seems like a pretty specialized task, so I doubt there’s a function written for it explicitly. So let’s look for a function that takes a list, and a boolean test, and splits it into two lists — one consisting of the elements satisfying the test, and the other consisting of the elements that don’t. That is, I need a function that takes a list of integers, and a function from integers to bools, and produces two lists of integers. No problem: I jump over to Hoogle and search for functions of type [Int] -> (Int -> Bool) -> ([Int], [Int]). It produces a short list of results, tells me what library they are in, and even gives a brief description of what the function does. I quickly see that partition is the function I want.

**** Great Haskell Advocacy . We’ve got all the usual things — source control by darcs, unit testing by HUnit, automated testing by Quick Check, and source documentation by Haddock. We’ve also got package management by Cabal (tied into Hackage, of course). We’ve got one other tool that is perhaps the strongest reason for the language — the Glorious Glasgow Haskell Compiler. You won’t find a more advanced compiler anywhere on earth. It produces code that is performance-competitive with C, has built in support for profiling, and features a rich interactive mode that both helps you test code and also explore types and interfaces.

Solving 11 Likely Problems In Your Multithreaded Code

MSDN Library 2008/11 - Joe Duffy

Server-side programs have long had to deal with a fundamentally concurrent programming model, and as multicore processors become more commonplace, client-side programs will have to as well. Along with the addition of concurrency comes the responsibility for ensuring safety. In other words, programs must continue to achieve the same level of robustness and reliability in the face of large amounts of logical concurrency and ever-changing degrees of physical hardware parallelism.

Binds functions to DOM elements.

Concrete tries to provide a new model of code organisation – a replacement for Object Oriented programming that is focused on adding functions to groups of DOM elements based on the structure and contents of those DOM elements. It’s a merging of the model and view layer that initially seems weird, but can give very powerful results. We’re standing on the shoulders of giants here – combining ideas from Prototype’s behaviour & lowpro and jQuery’s effen & livequery (who themselves stole ideals from Self’s Morphic UI and others), but extending & combining the concepts presented in those tools to provide a complete alternative to traditional OO concepts – self-aware methods, inheritance, polymorphisim and namespacing without a single class definition.

It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls. Efficiency. The Closure Compiler reduces the size of your JavaScript files and makes them more efficient, helping your application to load faster and reducing your bandwidth needs. Code checking. The Closure Compiler provides warnings for illegal JavaScript and warnings for potentially dangerous operations, helping you to produce JavaScript that is less buggy and and easier to maintain."

The Closure Library is a broad, well-tested, modular, and cross-browser JavaScript library. You can pull just what you need from a large set of reusable UI widgets and controls, and from lower-level utilities for DOM manipulation, server communication, animation, data structures, unit testing, rich-text editing, and more. The Closure Library is server-agnostic, and is intended for use with the Closure Compiler.

It is amazing how easy it is to sail through a Computer Science degree from a top university without ever learning the basic tools of software developers, without ever working on a team, and without ever taking a course for which you don’t get an automatic F for collaborating. Many CS departments are trapped in the 1980s, teaching the same old curriculum that has by now become completely divorced from the reality of modern software development.

To learn to program effectively you need to work collaboratively on projects with other people.

最初のフェーズは、Googleが作った製品としてのGoogle WaveがWebアプリケーションとして一般に公開される。第二フェーズのGoogle Waveはプラットホームだ。上で述べたように、一般のデベロッパが参加して何かを作っていく。そして第三フェーズでは、Google Waveはプロトコルだ。すなわち、Webコミュニケーションのための開発プラットホームになる（実装は自由で多様化）。

Im writing a series of tutorials on x86 assembly for C programmers who are already familiar with many of the basics of programming and computing. The assembly tutorials available online just arent doing it for me, and I need something organized the way I think, on the topics Im interested in, presented in a way which make comprehensive understanding easy. Ill do the work, go find the answers, and then drop everything here for you to enjoy.

argues that the process of requirements elicitation as project definition are secondary to the process of creation,testing and learning about nature.

What I cannot create I do not understand. --- Learn how to solve every problem that have been solved. --------- 1) The Space Shuttle Main Engine... many different kinds of flaws and difficulties have turned up. Because, unfortunately, it was built in the top-down manner, they are difficult to find and fix. 2) avionics system, which was done by a different group at NASA: The software is checked very carefully in a bottom-up fashion. First, each new line of code is checked, then sections of code or modules with special functions are verified.

Here is a funny story. My son, Vlad, (he's 11) always plays pranks on me... and one Saturday while I was sitting on the toilet reading the news on my handheld internet enabled computer (Nokia N810), I heard him saying to my wife "I saw a weird animal outside, around the cat door dad made!". Curious to see what he is talking about, I fired up VNC and connected to the laptop that handles the cat door and.... here is the picture I found...

This strategy is stated perfectly by Flickr's Myles Grant: The Flickr engineering team is obsessed with making pages load as quickly as possible. To that end, we’re refactoring large amounts of our code to do only the essential work up front, and rely on our queuing system to do the rest. Flickr uses a queuing system to process 11 million tasks a day. Leslie Michael Orchard also does a great job explaining the queuing meme in his excellent post Queue everything and delight everyone. Asynchronous work queues are how you scalably solve problems that are too big to handle in real-time.
