Fast, manual, incremental updating of WordPress

February 6th, 2008

WordPress recently released 2.3.3 as an urgent security fix for 2.3.2. Rather than wiping all non-configured files from my development site, extracting the replacement files from the tarball, and re-uploading said files by FTP, I used the fast and precise approach: Only upload changed files.

Creating images with javascript

August 24th, 2007

If you feel like being a little bit silly today, you might check out some code I wrote to generate BMP images right in the browser, using javascript. For maximum compatibility, I'm using the v3 header and uncompressed 24-bit color.

All mine does so far is generate a quasi-random bitmap. The same technique could be used to generate very small rounded-corner images and other progressive enhancements. Perhaps some other file formats might be interesting to play with as well. Excel spreadsheets, perhaps? I don't have much interest in continuing work on javascript-based file production, but I'd love to see other people take this idea for a spin.

Duplicity + Amazon S3 = incremental encrypted remote backup

August 11th, 2007

Update: I haven't really been using this, since the bandwidth required is a bit... excessive. I think I'll stick to duplicity + external hard drive.

Duplicity is a backup program that only backs up the files (and parts of files) that have been modified since the last backup. Built on FLOSS (rsync, GnuPG, tar, and rdiff), it allows efficient, locally encrypted, remote backups.

Amazon S3 is a web service that provides cheap, distributed, redundant, web-accessible storage. S3 currently charges only $0.15 per GB-month storage and $0.10 per GB upload. The API is based on HTTP requests such as GET, POST, PUT, and DELETE.

The following is a description of how I made use of these to back up my laptop, which runs Ubuntu Feisty Fawn.

Why I’m using Windows nagware on my Linux box

April 26th, 2007

When I switched to Linux a couple of years ago, I was able to find excellent replacements for most of the software I used on Windows. In a couple cases I had to use Wine to run my favorite Windows-only programs until I was more comfortable with the replacements, but there was one that I never gave up: Textpad.

My first collaboration!

January 12th, 2007

A while back I wrote a very simple plugin for WordPress that would automatically insert Dublin Core metadata into the header of my blog posts. I released it under a free license (as version 0.2) with the hope that someone more proficient in WordPress than I would come along and build on my work. And someone did!
