As a PSA (public service announcement), I'm reporting here that updating your Yosemite system to 10.10.3 is incredibly toxic if you use WiFi.
I've seen other reports of this, and I've experienced it myself. What happened is that the update for 10.10.3 seems to have done something tragically bad to the WiFi drivers, such that it completely hammers the network to the point of making it unusable for everyone else on the network.
I recently decided to have a look back at some old stuff I wrote. Blast from the past stuff. One of the things I decided to look at was the very first open source program I wrote -- something called vtprint.
Last month, Oracle released Oracle VM Server for SPARC release 3.2 which includes numerous enhancements. One of these is improvement for virtual disk multipathing, which provides redundant paths to virtual disk so that disk access continues even if a path or service domain fails.
When Docker first rocketed into the nerdosphere in 2013, some wondered how we at Joyent felt about its popularity.
