My PowerMac G4 400MHz with Debian GNU/Linux 4.1 (that works as my home server and internet gateway since last summer) just got 157 days uptime (without reboots since January 28th 2009) before yesterday strange hanging that was resolved by manual rebooting…

P.S. Electric power stability is provided by APC Back-UPS ES 750 that may keep the server working without electricity for more than 40 minutes!

P.P.S. Last “north-easter” poweroutage proved that my system’s up time without electricity is 75 minutes!!!

Some benchmarks of memcpy function on my Compaq Presario S6000NX Celeron 2.7 GHz (Linux), PowerMac G4 400 MHz (Linux) and PowerBook G4 1.67 GHz (Linux and Mac OS X):As we can see vectorized memcpy on PowerPC G4 1.67 GHz almost twice as fast as Celeron 2.7 GHz (which is sometimes similar to speed of vectorized memcpy on PowerPC G4 400 MHz). Also we see that Mac OS X has vectorized memcpy by default. See source code of … Continue Reading

Probably I will do some upgrades as second Ethernet interface, additional memory and new battery for clock. I plan to use it as router and home web-server and … Continue Reading
