devGuide.tv Live!

We are experimenting with doing a live TV show on the Internet. It will be called devGuide.tv and it will be about IT, new technologies, OpenBSD, and Open Source.

Some of the shows will be closed, but most of them will be open to general public. More details coming up soon. For now, if you see a prompt asking you to enter a password, use mysecret.

We would like to host the shows at around 5:00~6:00 PM (GMT) and 10:00~11:00 AM (GMT), but for a while it is going to be a hit and miss thing, whenever Jacek has the time to do them.
