Re:Seed, damn you!
Try http://ftp.linux.cz/pub/linux/fedora-releases/9/ (especially if you are in europe). We still have some free bandwidth.

FC5 mirror
The Fedora Download page, which is according to the announcement message supposed to redirect you to one of the mirrors, does not work - it redirects to ftp://download.fedora.redhat.com which is (of course) busy. So let me allow to advertise my mirror - if you are in Europe, I have still about half a gigabit of bandwidth free at
ftp://ftp.linux.cz/pub/linux/fedora-core/5/

Re:Made me look
by the way, if someone's interested on the newest development snapshot, try this: ftp://ftp.linux.cz/pub/localization/OpenOffice.or
g /devel/680/

Re:Filesystem?Disclaimer: I run one of the kernel.org mirrors.
Ext3 vs. Reiser is not an issue here. FWIW, I use XFS on my mirror volume, and I have also noticed how the git repository increases load on my server. See the CPU usage graph of ftp.linux.cz - look especially at the yearly graph and see how the CPU system time has been increasing for last two months.
The problem is in rsync - when mirroring the remote repository it has to stat(2) every local and remote file. So the directory trees have to be read to RAM. Hashed or tree-based directories (reiserfs or xfs) can even be slower than plain linear ext3 directories, because you have to read the whole directory anyway, so linear read is faster.

Fast mirror in Europe
My mirror has still lots of bandwidth left. Feel free to use it, especially when you are in Europe.

Re:Mirror in EuropeNow the server is somewhere near saturation, but still not maxed out: 440 FTP users,
350-400Mbit/s outgoing traffic, load average around 15-20. Server statistics are here. The server is 2x Opteron 244, Tyan S2882, 4GB RAM, 4x 120GB and 4x 180GB HDD (to be upgraded to 8x 250GB soon).
The usual (non-release-day) load is 30-100Mbit/s, ~150 FTP users.
Usually the first day downloaders have faster lines, so the second or third day the server might be fully loaded even at lower outgoing speed, because the read-ahead will not matter anymore.

Mirror, EuropeFor those who do not have bittorrent client, my mirror has still plenty of unused bandwidth. So feel free to use it, especially if you are in Europe.

Mirror (Europe)My mirror still has ~100 Mbit/s of free bandwidth. If you are in Europe, you may want to use it instead of the master server.
Hope this helps,

Re:Five minutes on slashdot...Yes, they have failed to update the mirror list they provide to users. Try for example this one.
Disclaimer: I am the system administrator of the mentioned mirror site.

Fast mirrorHello, I have a fast mirror, also available on IPv6. Mandrake has broken mirror-checking scripts, their list of mirrors is > 1 day old, even though they claim they update it every 10 minutes. So don't bother to contact any of the four mirrors which are currently listed at their site.
And, of course, consider joining Mandrake club after downloading the distro.

Mirror in Europe
My mirror still has some 30 Mbps of free bandwidth, so if you are in Europe, you can try to download from it.

Wow, IE fetches gopher linksI had never pointed IE at a gopher server. Dare I say I am just ever so slightly impressed? Perhaps not. When UMinn decided to charge, I wrote them a perl script which implements a gopher client in about 50 lines.
I dont guess they ever made any money of gopher at UMinn, but perhaps we shouldn't have been so hard on them for trying. Bygones.

Mirror in Europe
a 100Mbps mirror in Czech Republic, Europe can be found at ftp.linux.cz.

Re:When slashdotted, here are mirrorsThe ftp.linux.cz has Mandrake 8.0 as well. Feel free to slashdot my mirror, it has lots of bandwidth even with Red Hat release downloads in progress.

Re:An open ftp for 7.1If you are in Europe, you can slashdot another Red Hat mirror, ftp.linux.cz as well. 100Mbps connected to 155+Mbps European academic network TEN-155.

Re:This sucks
The "way to manage this" would be RPM. Of course, it is defeated by the filesystem layout differences between some distros, but that's what FHS is supposed to eventually fix.

Re:Question from a non-guruThe reason is that the driver interfaces haven't stabilized to the point where it makes sense to define a binary interface for drivers. The interfaces are making signficant and sometimes radical changes that are necessary to keep the kernel improving. Once the kernel has developed "enough", the driver interface (at least for certain types of drivers) will probably stabilize and become de facto standard or be blessed by Linus as standard.
The situation is more different than you would think. Linus (and many other kernel hackers) thinks that there is no need for supporting binary-only drivers and thus make no effort of keeping the driver interface stable over time.
Many binary-only drivers even violate the GPL by using the inline functions from the (GPLed) kernel header files. I think Linus gave only one explicit exception from this rule to some company (etinc, I think).
IMHO it is hard (if not impossible) to write (and especially maintain) the Linux driver not covered by GPL. You basically end up duplicating the changes in the kernel develoment yourself.
Speaking from the point of view of kernel driver author/maintainer it is the best thing for maintainance to have your driver included in the mainstream kernel tree. Core kernel hackers often modify drivers in the kernel tree to reflect changes of the driver interface, so you don't have to track closely the kernel development.

NUMA for LinuxHey, I wonder if IBM is actually gonna write a NUMA layer for linux? I mean, if they don't then all you end up with a buncha 4-way rack mounted linux boxes.. for $365,000 apiece.
The (preliminary) NUMA support for page allocations is already there, written by Kanoj Sarcar of SGI. Look at linux/mm/numa.c

RedHat probably did something wrong wrt mirrorsI am a maintainer of ftp.fi.muni.cz (aka ftp.linux.cz), which is one of the official mirrors of RedHat Linux. On the RedHat mirror-list they asked us (mirror maintainers) to mirror the 6.1 release, but to not make it available until Monday 4pm UTC.
But: They left their FTP servers open for public downloads of the RH6.1, which does not make sense for me (they have a separate host rh-mirror.redhat.com for mirrors downloading).
Does anybody have an explanation for this?

glibc 2.1 and sshSo far I've seen just quick hacks which allowed ssh to compile, but e.g. disabled correct utmpx support. There were a couple of bugs in ssh related to glibc2.1, especially in the sparc code, one bug in the spec file which rpm 3.0 does not like, etc.
You can download the source rpm for RedHat 6.0.1 from the UltraLinux site. In addition to this, there are RH6.0.1 rpms for SPARC. Sorry, don't have any machine but E3500 running RH6.0. The package is international, so if you want a US version, change Release in the spec file to 5us instead of 5i.

UltraSPARC Linux is boss. It's free. Try it now.
Linux UltraSPARC has been available in full 64 bit version for several years. See this slashot article or better yet check out the UltraSPARC Linux Home Page. Linux beats the Johnny come lately handily.
