Every other week I find myself solving some kind of problem that involves matrix operations or other linear algebra concepts. I still have my old TI-89 from when I was a student. It’s a handy calculator, no doubt about that, older people will even call it a luxury. But quite frankly, I don’t know why we should use calculators considering the speed of an average personal computer. Or even a cellphone in case you’re thinking about throwing the portability argument.
Anyway, rants aside, I was bored so I put together a tiny javascript library with basic linear algebra functions.

Galleria is an awesome slideshow gallery built on top of jquery.
After trying out about 10 different picture slideshow plugins for wordpress I couldn’t find one that would do what exactly what I want. For some reason, none of the plugins I tried was able to display more than one gallery in the same page. I wonder what use scenarios fall into that stupid restriction. Personally I don’t see any point on installing a picture slideshow plugin and use it once, but that’s just me.

So I ended up rolling my own. I googled around and picked galleria out of many javascript slideshow scripts, and wrapped it in a wordpress plugin.

Grab it from github.
