Recognized shorthand on the Usenet group comp.std.c for any unexpected behavior of a C compiler on encountering an undefined construct. During a discussion on that group in early 1992, a regular remarked “ When the compiler encounters [a given undefined construct] it is legal for it to make demons fly out of your nose…
On occasion you meet a developer who seems like a solid programmer. They know their theory, they know their language. They can have a reasonable conversation about programming. But once it comes do…
You've finished this book and have decided to continue with programming. Maybe it will be a career for you, or maybe it will be a hobby. You'll need some advice to make sure you continue on the right path and get the most enjoyment out of your newly chosen activity.
Dylan? C# 3? Perl 6? Does it have deterministic destructors, even as blocks like Python 2.5? Generics? A powerful macro system? Even as described it sounds like magic, but not a moment too soon.
I'm no graphics expert, but appreciate why square roots are useful. The Pythagorean theorem computes distance between points, and dividing by distance helps…

Update 2014.12.17: Now that SSL is encouraged for everyone and doesn’t have performance concerns , this technique is now an anti-pattern . If the asset you need is available on SSL, then always use the https:// asset.
Explaining the Dependency Injection pattern, by contrasting it with Service Locator. The choice between them is less important than the principle of separating configuration from use.
A crit-bit tree can be used as a high-speed associative array. For example, an array mapping 54 to 1, 19 to 2, 99 to 3, 85 to 4, and 88 to 5 can be stored as a crit-bit tree containing 54=1, 19=2, 99=3, 85=4, and 88=5. The smallest string in the crit-bit tree larger than 85= is 85=4.
In an earlier post I mentioned that one goal of the new introductory curriculum at Carnegie Mellon is to teach parallelism as the general case of computing, rather than an esoteric, specialized sub…
I think the only serious gripe is what you call your biggest gripe, and I must say that I envy this in Haskell. As you know, in the eager world we tend to write out our own recursive functions, rather than use combinators. You give part of the reason; the other part is that deforestation and related transformations…

The first three newsgroups created inside Netscape (then Mosaic Communications ), when our news server went online the first time, were mcom.general, mcom.humour, and mcom.bad-attitude.
In the first of this series of articles, I'll look at how a CPU can be emulated through JS, and start building an emulation core for the GameBoy console.
I wrote this while I was at PyCon, but I kept revising it. Anyway, here goes. :) As is apparent by now, no one has really been doing any ...
This paper appeared in Communications of the ACM in April 1960. It is the original paper on Lisp.
How to select files, read file metadata and content, and monitor read progress.
Craft is a demo running on its own minimalistic demo platform. The demo platform is based on an ATmega88 microcontroller.
There has been a sudden resurgence of interest in my "donut" code from 2006 , and I've had a couple requests to explain this one. It's been five years now, so it's not exactly fresh in my memory, so I will reconstruct it from scratch, in great detail, and hopefully get approximately the same result.

How to program independent games
Google’s Chris DiBona emailed me this morning to tell me that unless I removed a specific line from the license of my jsmin-php project (a PHP port of Douglas Crockford’s JSMin ), Google Code would no longer host the project.
FOUT is what I’m calling the flash of unstyled text that you get while using @font-face in Firefox and Opera.
Context free grammars (CFGs) are a valuable theoretical tool on which the modern compilation theory relies for parsing the code of programming languages. For example, the most popular tool used for parsing – YACC , generates parsers for CFGs. What most people don’t know 1 is that the vast majority of programming…
