Linux on Mac Mini – power on after power loss

The Mac Mini doesn’t save this information in its BIOS (or equivalent), so you need to set it on each boot. I use my distribution’s /etc/rc.local file for this. Either way, these are the commands to run (copy, and uncomment the correct line for your Mini): ## PPC Mac Mini #echo server_mode=1 > /proc/pmu/options ## […]

Cool Software: Batch File Compiler PE

While I’m not sure why you’d want to do so, compiling batch files into executables just has some hackerish appeal to me. The batch file compiler does so, and includes a cool syntax highlighting editor as well! Get it here: http://www.bdargo.com/ bfcpe.exe

Checkinstall is in the standard Debian repositories and encapsulates your install into […]

Fixing “shmget() failed: No space left on device”

I had this happen when someone ran a script to kill x11vnc every so often, using kill -9 (don’t ask). Killing x11vnc with SIGTERM (15) allows it to clean up its shared memory segments. SIGKILL (9) will not. Googling around, I found a script over here (backup copy here). The problem with that was that […]

SSH in a while loop – stdin problems
