  • Updated CSS Mastergrid

    March 31st, 2008

    I’ve finally updated my CSS Mastergrid to show more browsers and browser versions. This includes a full re-test of all browsers. The most pertinent versions on the list are Webkit and Konqueror versions, Netfront and the Playstation 3 browser, and other mobile browsers including Microsoft’s Deepfish beta. The revised list is at its usual place here more »

  • CSS hacks series

    March 6th, 2008

    This is an updated version of an article I first released December 2005. I try to keep it up to date, and only feature hacks that are as forward-looking as possible. It is far more likely that hacks targetting the latest versions of a browser will change than those targetting an older version, so exercise the usual caution one should apply to CSS hackery. Latest updates: more »

  • Mutually-exclusive stylesheets, take three

    March 6th, 2008

    Once again, I’ve updated my mutually-exclusive stylesheets technique. Now it classifies fewer browsers as “modern”, and is much more straightforward and aesthetically appealing than the old version. I have yet to test it thoroughly, but it seems to be working properly in Windows-based browsers. Perhaps soon I will be able to test it in MacOS, but we’ll see. more »

  • Updates? Wow..

    March 6th, 2008

    Yes, I realize it has been a long time since I updated the page. Time is ever at a premium, but I couldn’t resist commenting about the new Internet Explorer 8 beta. I’ve started to finally fix the page more »

  • Dancing with the devil: a look at the IE8 beta

    March 5th, 2008

    I felt a bit adventurous today, so I downloaded the IE8 beta. I can report that things are improving for the better, and IE8 may be what IE7 should have been. I see obvious wins in scripting performance and CSS parsing, although I have only had time to barely scratch the surface. There are a couple of oddities, but I’m finally starting to grow optimistic about an Internet Explorer release. more »

  • Robocode and JDK xlib locking glitches

    October 3rd, 2007

    Being a Computer Science TA, I often get the fun of tinkering with random OSS projects. I was trying out Robocode in Gentoo when bam: xlib locks were failing. This happens quite a bit lately with old software (ahem, Matlab) due to libxcb changing about once a microsecond. You get a wonderfully cryptic error more »

  • Easily test Opera Mini in XP/Wine

    September 14th, 2007

    Thanks to Freakitude, I can now run Opera Mini versions not available as an online simulator. This technique creates a Windows executable that requires nothing but the MidP DLL file. I have no trouble running these in Windows XP or the latest versions of Wine more »

  • Of mastergrids, Opera 9.5 hacks and SVG equation editors

    September 4th, 2007

    Since Opera 9.5 is out I figured it would be a good time to update my CSS hack mastergrid. I discovered what appears to be a proper Opera 9.5-targetting hack while doing this: more »

  • Mutually-exclusive stylesheets, take two

    June 16th, 2007

    Finally I have figured out a minimal hack that will let you use two stylesheets for a page, one for basic CSS support for older browsers (including IE6 and under), and the other including an advanced stylesheet for modern browsers more »

  • Using SQL arrays for efficiency

    June 13th, 2007

    Here is the situation. You have a database of items. Each item has a frequency count. For each item you want to count the number which have the same frequency, lower frequency, and higher frequency. The naive way of doing this is something like this (in pseudocode) more »
