A few days back I posted a story about a crock-pot powered by Linux, but I had no idea that Linux is also used for firearms targeting systems. What an interesting application for an operating system. I have an AR-15 and it’s a very fun gun to shoot. It’s light-weight, with little recoil and is quite comfortable to hold. However, my AR-15 doesn’t even have a scope on it. I can’t imagine how much easier it would be to shoot long range targets with a Linux-powered targeting system like the one mentioned in the article.
