Color combinations for web sites

I’ve stumbled across two interesting tools recently. The first is the Mac application ColorDesigner, which generates random color combinations with lots of tweakable knobs. The second is Cal Henderson’s online color-blindness simulator, designed to show you how your choice of text and background colors will appear to someone with color-deficient vision.

I decided to try to merge the two together into a single web page, using Mason and Cal’s Graphics::ColorDeficiency Perl module. It’s not done yet, but it’s already fun to play with: random web colors.

Right now, the randomizer is hardcoded, but as soon as I get a chance, I’ll be adding a form to expose all of the parameters.


Teresa Nielsen Hayden of Making Light has a charming way of dealing with obnoxious commenters: she disemvowels them. This seems to be far more effective than simply trying to delete their comments or ban their IP addresses. She apparently does it by hand, in BBEdit. Bryant liked the idea enough to make a plugin that automatically strips the vowels out of comments coming from a specific set of IP addresses.

I don’t have any comments to deal with at the moment, but the concept amused me, and I wanted to start tinkering with the guts of MT, so I quickly knocked together a plugin that allows you to mark individual entries for disemvoweling. While I was at it, I included another way to molest obnoxious comments.



Simple little MT plugin, created as a generalized alternative to FlipFlop.

Baby's First Perl Module

My blushes. I’ve been hacking in Perl since version 2.0 was released. In some ways, it’s my native programming language. It’s certainly the one I use the most, and the tool I reach for first when I need to solve a problem.

But I haven’t kept up. Until quite recently, I was really still writing Perl3 with some Perl4 features, and regarded many of the Perl5-isms with horror. It felt like the Uh-Oh programmers had crufted up my favorite toy, and it didn’t help that the largest example of the “New Perl” that I had to deal with was massive, sluggish, and an unbelievable memory hog (over 9,000 lines of Perl plus an 8,000 line C++ library, and it uses up 3 Gigabytes of physical memory and 3 dedicated CPUs for its 25-hour runtime (“Hi, Andrew!”)).
