Moving Pic of the Day Foiled Again

By barneyb on March 10, 2010

A while back I made an attempt to move Pic of the Day (NSFW) off of ColdFusion 8 and onto Railo 3.  I can't afford a license of CF9, so my only upgrade path is through a free alternative.  Unless someone has an extra four grand they want to give me….
Last time I was foiled [...]

Fake Filenames for Far Future Expires Headers

By barneyb on March 10, 2010

Everyone knows that one of the best ways to increase page performance is to reduce the number of HTTP requests required for related assets.  There are a pile of ways to approach this (JS/CSS aggregation, image sprites, caching), but the best (and simplest) is client-side caching.  It doesn't help your first-time visitors at all (which [...]

REReplaceCallback UDF

By barneyb on March 10, 2010

If you've used pretty much any modern language, you know all about callback functions.  Unfortunately CFML is capable of doing it, but the language itself doesn't leverage the feature anywhere.  In particular, a callback for the replace operation is of great value.  Ben Nadel has blogged about such things a couple times, and now I'm [...]

A Drastic Change

By barneyb on March 1, 2010

So today I decided to upgrade to WordPress 2.9.2 (I'd been running 2.7 since forever), and unfortunately it broke K2, which is the theme I've been using since I switched to WordPress years ago.  K2 was a solid theme, but it started getting rather unstable I thought, so it was hard to get a good [...]

Wow Am I UGLY!!

By barneyb on March 1, 2010

Yeah, so apparently WordPress 2.9 totally broke K2.  My apologies for the horrific appearance of the site, though I'm delighted to say the admin area still looks awesome!  Or something.  I'll get it fixed here shortly, I promise….
UPDATE: apparently WordPress not only deprecated `attribute_escape`, they also changed it's functionality (despite it's widespread use in the [...]
