I didn't mean 10,000 simultaneous users. In a given day during peak hours I would estimate (and my memory is a bit fuzzy here-- it's been a decade) around 200-300 users online.
I was the OpenVMS group lead for a government entity that had a user base of 10,000, 6 (SIX!) Vaxes, and a simultaneous user count of over 3,300. We were told by DEC at the time that we had the world record. I'm damn proud of that and the people I worked with to make that happen. Although I left there a few years later, the group maintained the cluster uptime and the last I heard they were over 7 years. The cluster at my new location has been up continuously for over 5 years - through data center power outages (we're split between 2 data centers).
It's awesome because it's hard. There are no multiple choice questions - it's all hands-on. You get a pre-configured system that you have to make a bunch of changes to, and you get a system that won't boot that you get to fix. You have to install a system from scratch and the list of things you have to set up and configure is *HUGE*. You either know the stuff or you will fail - you certainly can't spend too much time looking through man pages. There's a good reason that over 40% of the people fail, and it's not because they're Linux experts without Red Hat experience.
I did great on it because I studied my arse off - many, many hours going over the online study guide, the online documentation, and hands-on on a test system.
What a crock. I've passed the RHCE (with a 100% score in all sections). At no point did I feel that I was forced to use any Red Hat specific utilities or conventions. The exam is purely performance-based - Red Hat doesn't care if you want to use postfix or sendmail, vi or emacs,, or how the services start up at boot, as long as the specifications are met. You have to know how to use anaconda, but that's about it for RH-specific things that I can recall.
Red Hat Professional Workstation. This is technically equivalent to RHEL WS and costs about $85 including a full year of RHN updates. That's actually *CHEAPER* than buying a boxed set of RHL 9 and buying a $60/yr RHN subscription.
Let me get my 2 cents in and state that my Dell PowerEdge Server 400SC is *VERY* quiet. One morning I walked over to it to turn it on and accidentaly turned it off, forgetting that I left it on overnight. You really have to stick your ear near to it to see if it's on or not. The CD isn't silent, but the rest of the system sure is. I've been buying PCs since 1981 and this is by far the quietest system I've ever had. When my next system gets replaced, it will also be a Dell. My office Dell dekstop is quiet too.
Costs next to nothing to make, but costs your life to get it.
Even MS funds various researchers, RH takes what's free and makes it not as free.
You sound like somebody who doesn't have a clue as to how many developers Red Hat has. If I remember correctly, 7 out of the top 10 kernel developers work for Red Hat. Many, many other packages have *significant* contributions made by Red Hat employees. Red Hat does a *lot* more than just take Joe Blow's GPL'd package and package it into an RPM.
Do you also realize that Red Hat has more developers working on Fedora than they did on Red Hat Linux?
Let's also not forget that Fedora IS free. RHEL isn't, but you are getting a level of support that Fedora doesn't give you.
I don't know about the IDE spec, but I did a quick search on faq.org for "master/slave" in the rfcs. I matched at least 16 RFCs (it also matches older versions of the same RFCs).
So, I guess you can't be RFC-compliant when bidding on LA County contracts...
Not only is Red Hat hosting Fedora, but they actually have more developers working on Fedora than they did on Red Hat Linux.
Let's not forget Red Hat Professional Workstation either. At $82 at buy.com, it includes a full year of RHN updates. Technically, it's the same distribution as RHEL WS - even the CDs are labeled RHEL WS (as is/etc/redhat-release).
Red Hat does to lots of customizations, and if download the source rpms, you can look at the changelogs to see what they've done.
If you download the source rpms and build a system yourself, you'll have trouble getting patches for that system - in fact, they're not available at all via RHN unless you pay the subscription fee to the right channel.
This does look promising. The donation component is not at the top of the list, and Tutos might fit the blll for the rest. I had looked at Amphora and it's a lot like Tutos, but Tutos is GPL and Amphora isn't. If I need to wrangle Tutos into a volunteer management suite, it would be nice to give my work back to the community.
I've defined most of those above - at least enough to get me started.
volunteers for what purpose?
The organization, Bundles Of Loveis a registered non-profit that makes and distributes clothes and supplies to neeedy babies and their families. Most of the goods get delivered to hospitals where the social workers determine need and distribute them to the families. The goods include burial garments for those babies that don't survive (you don't want to hear the stories).
I've already got a bulletin board up and that's a very small piece of the equation. I need to be able track volunteers - names, addresses, e-mail addresses, etc. I'd like to track relationships between the volunteers - i.e. 1 address for a couple. We need to have the ability to send e-mail to any pre-defined subset of those. For example, a volunteer could in the north metro region and be a coordinator. I should be able to send e-mails to all north metro volunteers, or all coordinators, and he'd get them.
I'd like to be able to generate paper-labels for volunteers that don't have e-mail, and send out e-mails to those that do.
We need to record all the hours that a volunteer worked, and then generate reports from those.
We need to track both incoming (both financial and non-financial such as raw goods) and outgoing donations (usually finished goods).
We need a place to centralize documents such as forms, inventories, etc.
I've certainly thought about writing it myself, but it's a *lot* of work. The user interface has to be super friendly since many of the volunteers have almost no computer background - way too many AOL users to feel comfortable around:-).
Certainly if anything does need to be written, the only way I'd relaase it would be via an open license. We simply can't afford to buy or contract out because we have no excess cash. The web server we're running on and even the domain name fees are donated - by me!
A discussion forum is part of the solution, but they're pretty common. I have to migrate away from wwwboard because of the spam we're getting, but it's just a matter of time before I find a suitable replacement.
Comparing that to Solaris, I have no idea where you pulled out the 11.5 year life cycle. According to Sun's web page, it's 5 years from last ship date. Reference this page: http://wwws.sun.com/software/solaris/fcc/lifecycle.html
I will admit that 5 years from last ship is greater than 5 years from initial ship, but there's no way in hell it's an 8.5 year delta like you're trying to claim.
Ya know, "gobs of system management tools" and "a kernel many tricks up it's[sic] sleeve" don't exactly add to much of a review:-). I believe I can honestly claim that Red Hat Linux Advanced Server has "gobs of system management tools" and "a kernel with many tricks up its sleeve". Of course, this claim holds true for Windows too.

Sure, why not? What about those people with a TiVo that demands a PPP connection even if you have existing Internet connectivity? Many people are looking for a solution to this issue since the only reason some people have a landline at all is for their TiVos. The rest of the time a cellphone will suffice. I suspect DirecTV people have the same issues.
If they tie the Office EULA to an OS, the anti-trust lawyers will get annoyed again. I believe the last thing MS wants is to have the Office group split from the OS group. Office is a *LARGE* business - the last number I heard was $4B per year in revenue. It's obvious that Office subsidizes Windows, and if the business units were separated, Office certainly would run on other platforms (after all, MS Office, Inc. would make a bunch of money if they sold Office for Linux or BSD or whatever if it didn't cost them a fortune to test and support it). Windows without killer apps (like Office) would be just another platform.
I firmly believe that if MS had released Office for the Amiga, we'd still see Amiga thrive in the marketplace, the Mac would be dead, and Windows 95 would never have come out (10 years after the Amiga came out).
>Just curious. Anyone got an actual definition of a SAN?
>[...]Plus.. a shared filesystem
Please see my earlier article. SANs typically do *NOT* offer a shared filesystem. My EMC-based SAN does not offer a shared filesystem to the majority of the hosts. What it offers is raw disk that look like SCSI disks, and then the hosts are responsible for sharing a filesystem on top of that (via Veritas Clustering, Windows (ughh) clustering, etc).
NAS, on the other hand, does offer shared filesystems, typically via NFS or CIFS.
Repeat after me: a SAN presents itself to the system like a disk controller - nothing more, nothing less. You typically run SCSI over fiber, so if your host can see the host bus adapter as a bootable device, then you can boot the system from it. The SAN disks look like SCSI disks.
A local company here has most of their mission-critical Windows servers (is that an oxymoron?) booting off their EMC SAN. If a single system has a hardware failure, they roll in a replacement, boot off the same SAN-based disk, and they're up in no time flat.
No, and it isn't even close. A typical SAN presents itself to the host as a disk controller. It has no knowledge of file systems (those who tell you to plug into a SAN because it's already being backed up are smoking dope - you *can't* back up the storage if you don't understand the file system). A SAN is a very expensive disk subsystem, and yes, you do get what you pay for. Because the SAN has no knowledge of file systems, any volume sharing is totally up to the clients to coordinate. Present the same disk to two systems that don't run some sort of clustering or file sharing software, and you *will* corrupt your data.
NFS, on the other hand, presents itself to your host as a file system. You share that storage with multiple hosts, and there is usually locking happening in the background. You don't have the same level of control or access on an NFS server like you'd have on a SAN.

I've got a 2-port Linksys KVM that came with cables. I used it between 2 Red Hat Linux systems, and currently use it between a Red Hat Linux system and a Win2K system. No issues whatsoever. The darn thing just works and cost me about $75 or so from buy.com.
KMail has a barely functional IMAP implementation that can't even tell you how many new messages you've got in each folder without changing to that folder.
The poor IMAP support in KMail is what drove me to Evolution, and I certainly have not regretted it.
Basically like IBM's VM, which predates OpenVMS Galaxy by, oh, a few decades.

Want shared memory between cluster instances? Sure, in a Galaxy running VMS. Want to do that with VM? Too bad...
