"I had a meeting with my probation officer today and he told me that he has to install monitoring software onto my PC. No big deal to me; that is part of my sentence," he wrote on his Lost and Alone blog. "However, their software doesn't support GNU/Linux (Which is what I use). So, he told me that if I want to use a computer, I would have to use an OS that the software can be installed on." The monitoring software in question is only available for Microsoft Windows. Neither Linux nor a Macintosh running OS X would be an acceptable platform.
