I mention this article because I think RHELCS has something to do with LVS, although this being Linux J, you won't find out from the article (I'm dropping my subscription, by the way, after 3 bad articles on LVS).
The only clue you get about a possible involvement of LVS is on p2 of the article where, after waxing lyrical in market-speak on the virtues of RHELCS, the author finally reveals what it does - it's high availability with load balancing - and the load balancing used to be called Piranha. Piranha has a special spot in my heart. http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.unsupported.html#pbs_nutshell The references at the bottom of the RHELCS article are all to Linux-HA websites and none to LVS. The article aside, it would seem that RHELCS has all the gui bells, whistles and monitoring tools that LVS lacks and that are an essential part of a commercial product. But underneath RHELCS is likely functionally equivalent to ultramonkey. (Why isn't RH sending patches back to us?) The author, Daniel Bartholomew, lives in NC (as I do). A google search finds that he's a member of TriLUG (as I am, but I don't go to meetings much and I don't recall having met him). His postings to TriLUG show him to be a normal helpful nice guy. google reveals no hits for the author with RHEL Cluster Suite but he did post to one thread in the Linux-HA mailing list. Other articles in this month's Linux J, written by people who aren't involved in the project they're writing about, include an article on Beowulfs, by David Morton, who doesn't post to the Beowulf mailing list. So why have I, after reading 3 bad articles on LVS in Linux J, not written a good one myself? The bigger question then is why don't people involved in projects write about them for magazines. An even bigger question is why do I subscribe to Linux J, when I can't think of anything I've learned from it in 10-15yrs of subscribing (if I want to understand/install/use a project, I usually download the docs). I enjoy reading Maddog's articles in Linux J - he has a more global picture of Linux and the social effects of computers than any of the coders. o After the first bad article on LVS, I wrote to the editors, listing the missconceptions and errors and offering the services of the LVS team to review any further articles on LVS. I got an unconvincing "sure, sure, we'll contact you next time", and they never did. o It takes time and after answering posts here and maintaining the HOWTO, I want to do other things with my time. Recently I posted a presentation I gave on LVS at UNC. They've been asking for a presentation for over a year and I haven't wanted to do it. Heaven's knows, if anyone should be able to give a presentation on LVS, I should and anyone who wants a presentation on LVS would reasonably wonder why I don't have one ready to go and be ready to give next week. The presentation took about a month of spare time to write. o There seems to be little overlap between people who write for magazines and people involved in the projects written about. When I post here, it doesn't take real long (since I know, before I post, whether I have the answer) and I'm attempting to solve someone's problem. Most of the time I get a reply telling me whether it was useful or not and I learn something. Writing for a magazine would take a long time and I won't hear anything back from the readers. Is anyone any better off, or did the magazine just fill another issue with content that takes up a subscriber's spare time, but doesn't help them? I wonder if all the other (non-technical) magazines I subscribe to have as little to do with the topics of the articles as does Linux J? Maybe I should drop all my subscriptions. Books on the other hand are usually written by experts in the field. At least the books I read are written by academics who are expected to write as part of their job and the books enhance their reputation. I doubt if anyone writing for magazines gets these benefits.
