Jonathan (Wowfunhappy) was slowly disliking Apple macOS updates. The experience was being chipped away with each update. I experimented with three candidates inside Virtual Machines: OS X 10.6 Snow Leopard, OS X 10.8 Mountain Lion, and OS X 10.9 Mavericks. Mavericks was the chosen OS Jonathan wanted to go back to. Then the hardware needed […]

uhubctl is Linux utility to control USB power per-port on smart USB hubs. Smart hub is defined as one that implements per-port power switching. According to USB 2.0 specification, USB hubs can advertise no power switching, ganged (all ports at once) power switching or per-port (individual) power switching. Note that by default uhubctl will only detect USB […]

Ryan Walker created Phantomdrive as many places don’t respect privacy laws – in certain situations you may be forced to unencrypt your media, or worse, assumed to be guilty.
