So today, I decided to 'port' some of the more useful/relevant PHP builtin array handling functions to what their equivalents in C might look like. Sounds kind of boring, I know, but the end result is both useful and re-usable, and is the kind of thing that people write over and over again... although C doesn't really have true arrays, pointer-pointers do the trick for string arrays (char **'s),

First off, just wanted to ask any one who's reading this to please send any and all suggestions you have re. topics/excercises/etc to use as one of the 365 days... I have a pretty decent list of stuff to do, things to work on, etc., but it will be good to have as many options as possible and as much material as I can to choose from when deciding on the mission for a given day.Also, as far as the

Problem: based on a given finite set of elements, find every possible combination of X elements, where X indicates 1 to X.Example: in the finite set of elements (A, B, C), all possible combinations of up to three elements would be ((A), (B), (C), (A, B), (A, C), (B, C), (A, B, C)) - this assumes that we would treat (A, B) and (B, A) as the same permutation of a 2-element subset, etc.Solution: if

That's right... one piece of working, usable, non-trivial code (ie: it actually does something useful), every single day, for an entire year.Ambitious? Maybe. Necessary? I think so... you see, at some unknown point in recent history, I made a conscious decision to strive to be The Best at what I do. And what I do, is Code. It's my Art. I don't do this for a living because it pays big bucks or I'm

The interruptable sequence is a web programming design pattern I recently identified and used in a site I'm developing. I tried to locate existing descriptions/definitions of this pattern with no success - I looked for 'interruptable sequence', 'tutorial pattern', 'sequence pattern', etc. without finding anything similar to what I'm about to describe, so I'm posting about it here in the hope that

Click the link to go to the god source repository - as of today, it looks like two of the three conditions I submitted for inclusion have now been added (the third being the mysql_failed condition, which may end up in some kind of auxillary gem or something, as previously mentioned...). So... look for these new conditions in god v0.6.0!complex.rbdisk_usage.rb

If you haven't checked out god yet as an alternative to monit or other system/software-monitoring tools, do yourself a favour and head over to that link for a while and then come back... it's an awesome little monitoring tool written in ruby that has all kinds of cool features, including event-based conditions that will activate as soon as a process dies instead of needing a periodic check, etc..

Filter vs. Nat? (Chicken vs. Egg, movie at 11...)A few years ago I had to setup a couple relatively complex firewalls (under Linux), and in the process managed to find some documentation on the order in which a packet traverses each table and it's rules.Sounds pretty basic, however nothing in the documentation or man pages for iptables itself explains how the tables relate to one another; for

So I finally got around to playing with GreaseMonkey... and I regret not doing it sooner, there's so much I could have done already!If you're not familiar, GreaseMonkey is a Firefox plugin that lets you add your own/custom javascript code to websites. And it's dead simple - based on a handful of specially formatted comments and a file-naming convention, your javascript becomes custom code you can

I was grepping through some logs the other day at home and I figured "wouldn't it be nice if I could pipe this through something that would highlight lines matching a regex instead of just having grep pull those lines out?" Wouldn't you know it, such a tool doesn't exist, as far as I can tell. Which is very weird, since I've already found it VERY useful...grep *will* give you context lines if you

This is a (very) small patch I wrote a while ago for the disk_writer plugin of xmms (an open-source X windows media player, modelled after WinAmp). The post in the link is pretty self-explanatory, it's taken from the xmms development list where I sent it... basically it simply modifies how the plugin build the filename to write to so that you get an 'auto-rotate' effect instead of overwriting

Recently, as part of another project, I needed some code to validate a URI string based on RFC-2396. The goal here was the ability to ensure that a URI was RFC compliant. As such, I decided to use a set of regular expressions which were directly modelled from the ABNF definitions in the RFC. ABNF is by it's nature a very close match for regular expressions in terms of usage, syntax and purpose,

So today I finally decided to start writing a proper blog, after toying with the idea on and off for a little while. Among other things, I want all of the random code I write to be freely available and accessible somewhere online under the GPL and it doesn't always fit nicely into existing projects/categories/paradigms/etc. I'll still send and/or upload whatever I can where an appropriate project
