This video was suggested to me by YouTube. Quite interesting. He mostly talks about Windows from the standpoint of having been a software engineer at Microsoft but he touches on Linux, too, and the idea that software being Open Source alone doesn't mean somebody couldn't have snuck something in there. The video is 17 minutes in length but I think it'd be enlightening even to those without coding experience.
And sharing this video is also a good excuse to show off the new feature for embedding YouTube videos directly into the Forum. Click on it and try!
I know it's not Linux but I wondered if anyone saw this post i.e. that the unread posts feature is working. :) Also wondered what anyone thought about YouTube videos being embedded into the Forum.
