Well, after a week of plinking along on the Pi in the UK I have remote access to from California, I finally got an error message that made me smile - "Insufficient disk space"! You really know you're in software development bliss when you've forgotten the old days when we used to watch every single byte of core/RAM and drum/disk space consumed, and you see that kind of message.
It really is strange that, even with 2 GB of SD card space, there's only a few hundred MBs of space available to the user on the Debian variant, and it fills up fast if you're doing much in the way of development on the platform. At that, I'm really just getting a feel for how things run in the limited resources of a Pi, but, I'm quite surprised and delighted to report that you can actually get some things done. Of course, you wouldn't want to build anything complicated, but, for run-of-the-mill, typical, day-to-day command-line sorts of things, it's quite adequate.
The fact that I've been able to get work done for five days in a row without a crash has contributed to this happy problem. I was in no danger of using up disk space when I kept having to set up my development environment every day. Heck, I was hesitant to leave any window open, much less running anything in it, not knowing for sure whether memory was being exhausted, the power was unstable/insufficient, or some other issue was causing the crashes.
Anyway, fair warning if you plan on doing much of anything beyond the plain-vanilla things included in the Debian release (and there really is a lot there) - you're probably going to need a bigger boat, or at least one with more disk space!
