Exactly one of the following statements is true. In Tetris, you can always get at least one line before losing. In Tetris, a sufficiently evil AI can always force you to lose without getting a single line, by providing bad pieces. Which one? Prove it. The setup I crea...
This will create the neccesary directories, install nginx and gunicorn under supervisord control and upload new configuration files made from templates on all the app-servers. Additionally it deploys the newest codebase from your local git branch.
<img src="http://stevehanov.ca/wavelet/cup.png"/> Let's say you have millions of pictures of faces tagged with names. Given a new photo, how do you find the name of person that the photo most resembles? <p> In the cases I mentioned, each record has hundreds or thousands of elements: the pixels in a photo, or patterns…

Objective-C remains an impediment for many programmers coming to the Mac or iPhone platforms — few programmers have ever experienced it before learning Cocoa, forcing two learning curves at once for new Cocoa developers. How did Apple end up with such a weird language? And for a company known to replace CPU…
This morning Miroslav Bajtoš asked "Why do C++ folks make things so complicated?" in response to my article on regular expressions in C++. Other people asked similar questions yesterday. My response has two parts: Why I believe C++ libraries are often complicated. Why I don't think it has to be that way. Why would…

How a computer scientist, a programmer and a developer differ in skills, focus and priorities, even though the terms are often used interchangeably.
This is too long and rambling, but to steal a joke from Mark Twain Blaise Pascal I haven’t had time to make it shorter yet. There is some discussion of this post on the git mailing list , but much of it is tangential to the points I’m trying to make here.

Last weekend I tweeted two links to two tweets by a poor guy who apparently got his MongoDB database into an unrecoverable state during shutdown whilst upgrading to a newer version. That tweet quickly made the rounds, and the next morning I saw myself staring at replies stating that it was all his fault, because he…
The terms lvalue and rvalue are not something one runs into often in C/C++ programming, but when one does, it's usually not immediately clear what they mean. The most common place to run into these terms are in compiler error & warning messages. For example, compiling the following with gcc :
Lua/APR is a binding of the Apache Portable Runtime (APR) for the Lua programming language . APR powers software such as the Apache webserver and Subversion and Lua/APR makes the APR operating system interfaces available to Lua, serving as an extended standard library. Thus far the following modules have been…
There has been quite a bit of furor and excitement on the Internet this week regarding some very public criticisms (and defenses) of MongoDB and its creators, 10gen . Unfortunately, a ghost from my recent past also resurfaced as a result. Let me begin by apologizing to 10gen and its engineers for what I said at JSConf…
Over the years, I've seen a lot of confusion about JavaScript function invocation. In particular, a lot of people have complained that the semantics of this in function invocations is confusing. In my opinion, a lot of this confusion is cleared up by understanding the core function invocation primitive,
