I love my Volt. I wish for a Tesla, but I'll have to wait for two things:
More money.
When I can just pick one up, instead of putting down money upfront and hoping they last long enough to deliver mine.
You need a small time script to collect data from your USB device (it's code was in C), then plot it in 4 dimensions in gnuplot? Perl. There are certain advantages to having the interpreter written together with the language, which is why perl kicks java around the block, speedwise, but not everything has to be super fast. At least perl doesn't go off on demented errands of its own at unpredictable times like java does. I'd guess most of us older guys thought that java was a joke - since it seemed bad C programmers couldn't stop leaking memory or using dangling pointers, java makes it all a reference. If you don't get that joke, you're not a real programmer.
Example 4d plot - this code is only a few very readable pages (and it's free to download on my site) since you can code in perl to make it look very C like and readable. It took entire hours to write, most of that figuring out gnuplot's strangenesses. http://www.youtube.com/watch?v=WJe0YBAXwPw The gui, not shown in this movie is pretty simple, but allows you to put in perl code (presets are saved) into edit boxes for axis mapping - you can paste an entire program in there if you want to do something really complex. And it managed to run on that much data in a fraction of a second while using the slow eval string 4 times per loop iteration on the raw input.
This would have taken a week in C (to write)...PHP? Does it do hardware, like finding USB stuff by-id?
