Red Hat provides updates for seven years after initial release. So RHEL 2.1, released in 2002, and roughly contemporary with Fedora version negative three[1], should be approaching end-of-life next year -- a few months after Fedora 8 is EOL'ed. [1] What we call "Fedora" used to be known as "Red Hat Linux". RHL officially ended with version 9. So call RHL 9 "Fedora 0". Continuing further back, RHL 7.2 was being developed around the same time as RHEL 2.1. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

But that's the fun part. :) At least, as a kernel monkey at Red Hat, doing devel work on Fedora is a lot more fun than doing it on Red Hat Enterprise Linux. RHEL just gets stale and boring too fast. Back-porting drivers and bug fixes to an ancient kernel isn't the most exciting thing. Working with the latest upstream kernel is a ton more fun. I run Fedora on all my own systems, as well as on most of the systems I have in the office (and most of them are rawhide). In fact, I'm running rawhide on the laptop I'm typing on right now. Though I do usually wait to upgrade from the prior release to rawhide on my laptop for a while after release, as the month or two right after a release is when rawhide is the least unstable... But once rawhide hits beta, its pretty solid -- like someone said about debian unstable, its rarely in such a bad state its not useable. Well, at least from a developer's standpoint. -- Jarod Wilson [EMAIL PROTECTED] ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I am running fc7 on latops desktops and servers at home. The only problem I have is evolution-alarm-notify which crashes when launched from the session. bugs logged all over the net on this one and it's not fedora specific. oh - and my pp port scanner hasn't worked since fc4. I haven't tried fc8 yet. the livna repo has all the multimedia stuff not included with distro. I also work with Debian etch *release* on a daily basis which is quite stable and security patched often. Multimedia licensing is strictly area 51 for this distro so be prepared to use another apt repo or compile from source which get's away from the release. Ubuntu is very nice - even cool. Stable and very easy to install. ie on laptops ;) I haven't gotten into the multimedia aspect of this one. I mention the multimedia aspect because it's not a trivial task to build everything without a repo if you want to burn mp3's, transcode or do anything with dvd's, but then again you've gotten mythtv up and running (bless the diety of your choice) so you're no stranger to this. Here's the list of everything I've had to compile using fc7: ivtv ndiswrapper don't get me started on the state if the native driver for my ancient (4 year old *gasp*) wireless card. the blacklist keeps getting longer... again this isn't distro specific.

Notes from CentraLUG, 7-April-2008, Coleman Kane, FOSS on Win32
Eight people attended the April meeting of the Central New Hampshire Linux User Group, held as usual at the New Hampshire Technical Institute Library, Room 146, on the first Monday of the month (see below, we're evicted until fall). Coleman Kane was the main presenter, showing us how the MinGW and GNU binutil packages could be used to create a cross-compiling environment to create Windows-compatible binaries on Linux (or actually, starting from BSD in Coleman's case). He had a great slide deck and example source (available at his website at: http://www.cokane.org/dokuwiki/talks/dev-mingw) and was able to push through 55 slides in 75 minutes in a comprehensible fashion. The pace was fast and furious as he covered all of the highlights, took questions from the audience, edited and compiled code, and switched the projector between his BSD box and a Windows machine to show the code running. Whew! Well done and very informative! CentraLUG's meetings will be on the road for the summer. The library will be closed for evenings during finals week (!) and the summer hours have the library closing at 6 PM until fall semester begins. "See you in ... October!" We'll be announcing the location for upcoming meetings Real Soon Now. You'll want to see Ben Scott's May presentation on "The Linux Server That Could: Setting up a Small Office Server" so put the date of May 5th on the calendar now! Thanks to Colman for his great presentation, to Bill Sconce for providing the nice projector, to the Tech for providing the facilities and to all who attended for their attention and participation. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

But... Sure. But build the default sudo. It wants /usr/local/etc/sudoers which you will probably want to modify. FWIW - I've never done an NFS /usr/local for Linux.

And most stuff doesn't have an uninstall. And some assume /usr/local isn't on an NFS drive nowadays. Package systems usually keep thier data in /var which isn't on a shared NFS drive and the configuration in /etc. As I said earlier, the need for NAS mounted application stores has gone away with $1 / MB disk drives. If the system has unused GB on the OS disk, there's room for locally installled stuff in a proper package.

It's pretty normal in the sense that Windows normally drives one batty with crap like this. :) FWIW, I was NOT able to reproduce the behavior you describe on my Win XP Pro SP2 box here at work.

Off-topic - Mounting multiple USB sticks on Win XP
A neighbor asked for help with mounting his USB sticks. He has directories mapped to drive letters D,E, and F to mimic partitions from the days when Windows could not handle large partitions gracefully. When a USB stick got inserted, it grabbed the D drive letter fouling up his software. I helped him find Control Panel/Admin Tools/Manage Computer/Storage/Drives and changed the USB drive to U. This seemed to work OK. It also appears to mark the drive letter on the device rather than configuring the system to start lettering from U. However, it turns out he has two USB sticks he uses for backup and data transport. He mapped the second one to V. When both USB sticks are mounted at the same time, only one stick gets a drive letter. The other stick is unlettered and unavailable unless he goes through the control panel to manually assign a drive letter. Is this normal Windows behavior? Is there a simple way to force drive letter assignments on USB sticks? Can you mount two at once? (My winNT box does not support USB so I can't do much research myself.)

With the ariel density these days I don't think rotation speed is so important anymore for transfer, at least for the average case, but the seek can still hurt.

Every kind of head-wear Linux I've ever used has been able to upgrade previous versions in-place. I think the latest RHEL can still, in theory, recognize and upgrade a Red Hat Linux 2.0 installation. Of course, I wouldn't expect *that* to go so well, in practice. 12 years is a lot of software rot. But you should certainly be able to upgrade CentOS 4.x to 5.x with minimal heartache, assuming your configuration is reasonable vanilla. Just boot the installer disc and it should find your installation and ask you if you'd like to upgrade. I'd still make a backup of everything. :) Things sometimes go wrong -- that's a universal rule. And if an OS upgrade goes wrong, it generally leaves the system unusable. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I'm helping a department of mathematicians here with 50% of them using either Debian or Ubuntu (the other half uses OS X). Their experience and computer-savvy'ness differs wildly, but most of them are quite happy with their desktops. Some run stable versions, some prefer Debian 'unstable' or Ubuntu's release of the day, be it 'alpha' or 'beta'... In case of Debian, unstable is quite stable actually and the software is pretty much recent. Ubuntu takes the 'unstable' from the name, adds some desktop conveniences and perhaps some stability. As far as gnuplot install, Debian/Ubuntu package management brings in all the dependencies, of course. 'apt-get install gnuplot'. If you want, you can build packages from Deb/Ubuntu source using standard Debian utilities *and* your custom compiler optimizations, for example, 'apt-build install gnuplot'. apt-build is configurable to take into account your custom settings and pass them to make/gcc. Of course you can still always do 'configure && make && make install' from whatever source you prefer. 'Scientific' is a wide area and you may have to check Debian/Ubuntu repositories for software that you need. Commercial Mathematica/Maple/Matlab also run well on both x86 and amd64 Debians/Ubuntus. We are mostly Dell shop here, with some IBM and custom-built machines thrown in. I still have to run into something that wasn't supported by Ubuntu.

Sometimes we want to do things the hard way. Well, then, it should be hard, shouldn't it? ;-) One thing you may want to try is getting the source package from the distribution. The RPM .spec file will indicate all its build dependencies, so you can figure out what packages you need, and what patches the distro people think are needed to make it work. You can also customize the .spec file to tweak the build configuration, if that's what you're after. Then you can build your own customized RPM packages, too. RPM makes this relatively easy. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Really only marginally different from CentOS of the same version level, both are rebuilds of RHEL, though Scientific does do a bit more customization for the (duh) scientific community.

Keep it civil. ) Hardware support depends more on the kernel and patches applied to it than it does what the packaging system is. Different distros have different policies on their kernels. * CentOS maintains the same kernel base for the entire release lifespan. Great for stability, but means a greater burden back-porting new hardware support. * Ubuntu follows the same general tack as CentOS, within a shorter lifespan. i.e., the upcoming Ubuntu release is going to have a 2.6.24.x kernel (iirc), and will for its entire lifespan, though they do back-port a fair amount of stuff. * Fedora's approach is to track the upstream kernel as closely as possible. For example, Fedora 9 will have a 2.6.25 kernel at release time, but will likely be up to at least 2.6.27 by the time it goes end-of-life. For all but the absolute newest hardware, the forthcoming Ubuntu and Fedora releases are probably about on par with their hardware support. CentOS/SL 5.1 lags behind a ways, and 5.2 will get closer, but will still lag behind a bit... -- Jarod Wilson [EMAIL PROTECTED] ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

It was derived from a RedHat ancestor, so it is ought to be familiar to RedHat folk. They have a new release every year typically. The updates are fairly quick in between.

Not only does it wear a lab coat, but it has updated graphviz and R releases. It's a RHEL clone like CentOS, so if you are having trouble with CentOS already, I'd assume you will see the same thing with SL. https://www.scientificlinux.org/ http://en.wikipedia.org/wiki/Scientific_Linux You should also look into Debian, it's Free, supportable, stable, has a hypnotising swirly logo, and over 3.5e3 packages available in it's repositories (perhaps the scientific calculation software you are looking for is already part of the release).

Have you tried adding the popular third-party repositories -- especially rpmforge? I find they often have what is needed, or at least, some of it. I usually install them, but then disable them by default, out of paranoia. Then I use some variation of the script below to make it easy to enable them "as needed".
