Doom 3 Source

nobody@domain.com (Cal Henderson) — Mon, 1 Apr 2013 15:10:30 +0000

This review of Doom 3's source release is full of tons of interesting stuff, even for non-graphics programmers. [via waferbaby]

Regexp Kung-fu

nobody@domain.com (Cal Henderson) — Wed, 27 Mar 2013 22:10:22 +0000

There are two answers guaranteed to show up on nearly every PHP question on Stack Overflow - use the mysqli/PDO extension instead of the deprecated mysql one (to avoid SQL injection), and that you can't parse HTML with regular expressions.

With that in mind, my favorite two answers:

How PDO is still vulnerable to SQL injection attacks by Anthony Ferrara
Parsing HTML with regular expressions by Tom Christiansen

Github March Wrapup

nobody@domain.com (Cal Henderson) — Mon, 25 Mar 2013 10:02:08 +0000

I've posted a bunch of projects to Github in the last few months and haven't linked to them anywhere, so here's a quick roundup of recently notable projects:

lib_timezones - A PHP and JS library to handle user-specified timezones properly, with reasonable client-side auto detection.
lib_classsify - A partial PHP port of Github's own linguist which can automatically detect the programming language, given a code fragment.
js-emoji - A JavaScript library to allow display of Emoji in then browser for OSs without native support (anything that's not OSX 10.8 or iOS 6)
lib_autolink - My old PHP URL-detection and linking library, updated to handle multiple protocols.
lib_solr_query - A PHP library to turn user-entered complex search queries into valid SOLR query syntax. Supports phrases, booleans, nesting, assertions and more.

Chrome Performance

Chrome continue to get better and better. Ilya Grigorik explains some of the optimizations going on under the hood in this chapter from an upcoming performance book. If you work on the web, it's a fascinating read.

JSON Processing

If you're working with JSON on the command line, then I can highly recommend jq for simple data manipulation. It let's you mine into JSON data using an XPath-like query syntax and makes quick work of extracting the stuff you actually care about. The source is on the githubs.

The silver searcher

nobody@domain.com (Cal Henderson) — Mon, 24 Sep 2012 17:01:06 +0000

The silver searcher is basically ack, rewritten in C to be crazy fast. If you're regularly using grep to search a codebase, this is probably a much better idea.

JavaScript meets BrainFuck

nobody@domain.com (Cal Henderson) — Fri, 10 Aug 2012 13:19:28 +0000

Patricio Palladino has done a really nice job with hieroglyphy, a library for turning any JavaScript code into strings of only ()[]{}!+. The explanation of his blog is a great read.

Compact UTF-8 Decoder

nobody@domain.com (Cal Henderson) — Fri, 10 Aug 2012 13:19:05 +0000

Björn Höhrmann's excellent compact UTF-8 decoder is one of those C masterpieces that makes you realize quite how powerful the language can be.

Blind hashing

nobody@domain.com (Cal Henderson) — Fri, 20 Jul 2012 09:55:35 +0000

In the wake of password-hacking-month (Linkedin, Last.fm, Yahoo, etc) Jeremy Spilman talks about an interesting idea for increasing the cost to stealing password databases, rather than just the hashing: part 1, part 2

Javelin JS

nobody@domain.com (Cal Henderson) — Tue, 10 Jul 2012 13:13:32 +0000

Javelin JS is full of interesting little things - always fun to find out what compormises other teams make to allow their particular development model to scale. The css classes vs sigils part makes a lot of sense.
