I was wondering about the contents of the site sudonull.com - seemed a mixed bag, not a tech blog. Apparently it's translated repost from habr.com - both sites serve from different networks, so I'm not sure they're legitimately affiliated, but could very well be.
The article very much looks like it's machine translated from Russian because some phrases are weird in English but make perfect sense if you translate them back. Also some screenshots are in Russian.
