Well that's good. I'll be sure to pay close attention to their suggestions.

I'm limited to x86 hardware because  its cheap, so it doesn't matter much to me if it feels cheap. As for Linux at 13, I can't say I was a very impressive user. My first memory of running Linux is actually of not running it. I got a kernel panic on the first try because I didn't know about boot loaders or about specifying a root= in grub. I know a bit more now, but I still can't write much more than a basic bash script of a few lines of assembly. And the PDP-11? Wow, I've only ever read about that thing. :-)

Yeah. My experience in lab has been that generally the measurements (if taken properly) are more than accurate enough for troubleshooting and adjustments. I'm clumsy though, so the calculations (at least the simple ones) are often faster for me. Breadboarding a full-wave bridge rectifier takes me 10 to 15 minutes, running the calculations can be done in under 2. :-/

That's for sure. Right now we are learning how to program basic stamp microcontrollers in class, and while I'm not fond of them (they use PBASIC: a proprietary programming language! Can you believe such a thing?) I can see how they require efficiency. I write an 820 byte program for one of these things that would follow a flow chart for troubleshooting diesel engines. It turned out that by shortening some output messages to the debug terminal and eliminating some stray CASE statements, the code could be squeezed into 70 bytes! The guy next to me actually didn't use the debug terminal (which requires a serial port connection to a PC) and managed to get his program into 20 bytes using dip switches for the simple yes/no questions! I am uncomfortable in hardware though, so I wasn't willing to use switches. :-(
