People tell me things...
Via reader Ed, a new version of OpenBSD is out with improved PowerPC and G5 stability and performance. I don't know much about OpenBSD, but don't let that stop you ;)
Also, Hack 5190 at MacRumors' PowerPC Forum dropped news of a new version of the Flash hack that has the old 10.1 plugin spoof itself as the latest v19. This should be useful to those of you using Cameron Kaiser's SandboxSafari.
In case you missed it, the PowerPC Hub just celebrated its fourth birthday with a video.
At the Ubuntu forums, I saw this Radeon UMS thread for users who need to disable KMS and can't get acceleration because the Radeon driver dropped UMS support. The new UMS-enabled debs are for Ubuntu 14.04, but just for giggles I tested them on Debian and they worked! I just had to install libgcrypt11 1.5.3 in addition to the debs provided--the libgcrypt11 in Debian was too old.
Finally, Apple's ruse to release El Capitan as x86 only to reveal it was PowerPC all along is up:
Spotify 1.0.8 on El Capitan detected as a PowerPC app
Nice try, Apple. If it weren't for those meddling kids!
