I picked up this $10 dumbterminal at Re-PC, thinking it would be fun and
possibly useful to have one. (There have been times when three seperate
people in my apartment were using net connection before. Not for anything
useful, of course.) Unfortunately, it needed a special keyboard which I
still can't find. It still worked on its own, however, meaning I could
send text to it, I just could get text from it.
(BTW, I choose the name Metatron because I had just finished Neil Gaiman
and Terry Pratchett's _Good Omens_, in which it was the name for the voice
Seeing a good excuse to learn ncurses, I ordered the O'Reilly book and
started programming. (The book is, sadly, a veryvery old O'Reilly and
poorly organized.) I ended up with metatron.cc,
stripchars.c, sysmeter.cc and up.c and a
useful display. I admit it is an motely collection, but I only wrote
metatron.cc myself. The others I found freely available (yay GNU copyleft)
and modified to fit my exact needs.
The screen shot isn't the best, but then again, it really is a
screenshot. On the left is the CPU usage bar. It shows the percentage of
CPU usage in user, low-priority, system and idle states. When this pic was
taken almost all of the processing power was going to Seti@Home, a
low-priority background task. The CPU stats are provided by the
The text on the display is a summary of recent webbed news, provided by a
friend's server. I just connect to a certain port and read it out.
Below the news is my current uptime. I'm kicking myself for not taking
this picture about an hour earlier, when I had 10 weeks 3 hours and 10
minutes uptime -- much more impressive. But I had to take Hesse down to
install a new UPS. This string is created inside of up.c and does nifty
things like break uptime in weeks, months, years and even decades.
(Which is pretty silly, since the internal kernel jiffies counter
rolls over after about 4 years uptime, putting you back to 0. At least
nothing crashes when this happens, as compared to Win95 crashing after
49 days uptime for similiar reasons.)
On the right is memory and swap usage. These also come from sysmeter.cc
(though I had to add them).
