Build a Secure Wireless Portal with Linux

Filed under
Software

Ever since wireless Ethernet was born, a sizable number of folks decided that it should be freely available to the masses at no cost. So we have official community wireless projects, coffee shops, hotels, and other businesses supplying free wireless Internet, and a lot of purposefully-unsecured private wireless networks.

Humans being what they are, admins of open wireless networks should be canny and careful. In these modern times you can be punished for what other people do, no matter how tangential your connection to them. Presumably most folks would prefer not to go to jail because someone downloaded child porn over their wireless link, or spewed forth spams, or published information displeasing to corporate types.

Initial impressions of PCLinuxOS 2014.08

I spend more time looking at the family trees of Linux distributions than I do looking at my own family tree. I find it interesting to see how distributions grow from their parent distribution, either acting as an extra layer of features which regularly re-bases itself or as a separate fork. New distributions usually tend to remain similar in most ways to their parent distro, using the same package manager and maintaining similar philosophies. When I look at the family trees of Linux distributions one project stands out more than others: PCLinuxOS. Read more
