Keeping up with developments in IT has been aptly compared to trying to drink from a firehose -- the water is there, but there is just so much of it! Just keeping tabs on Linux developments is enough to leave your day hourless, so here is a Web site, linuxpipeline, which helps to channel the flow.
Covering news, trends, demonstrations, products, applications, and offering a free newsletter and a glossary, this site probably deserves bookmarking.
Incidentally, I was alerted to this site by Scott Finnie's Newsletter:
http://www.scotsnewsletter.com/subcenter/subscribe.asp?type=subscribe
which is a sufficiently valuable resource that I can plug it here without shame. It is free, but donations are solicited, and it is some measure of the exteem in which I hold it that someone as notoriously reluctant to part with a buck as I has nevertheless contributed cash to this in the past, and will do so in the future.
