Linus Torvalds himself said to not use it for a couple of builds.

"There is still something strange going on that seems to be triggered by preemption, so for now we suggest not enabling CONFIG_PREEMPT if you want the highest stability. On the other hand, I'd love to have more testing, so that we can try to figure out what the pattern is - but please mention explicitly that you ran with preemption if you have problems."

Someone else reported that it was just a mistake on the part of one of the testers, which was revealed http://article.gmane.org/gmane.linux.kernel/163190 .

Who is a troll -- a person who follows what Linus says in official annoucements, or some random person who says, "works for me" in a rude way?

So preempt must still be broken, as it has been since test10. Don't use it.

Actually it was figured out that the reported problems with preempt were really caused by user errors.

No kernel bug -> no fix needed.

"The only way to do it without modifying the cache controller to do distributed cache coherency is to turn off the data cache completely."

Not true, because pages can be marked read-only, or even marked to fault on a read, at which point the OS can use mutexes/semaphores across any type of network to ensure data coherency. And IIRC, both openssi and openmosic either already can do that, or will be very soon (follow the links, or search for migShm).

Again, latency will suck compared to shared memory on SMP or true NUMA, but it will be shared memory with no other difference than the latency and bandwidth.

Where is this documented? A google search suggests that it uses "${var}" bracket notation, not "$(var)" notation as I had written.

t's possible to run serious production servers that need recent-version daemons using Gentoo defaults for compile options and with a nicely-rationalized /etc/*/ tree for the configuration options. If you want to accomplish the same with Debian you're going to have to custom-compile your major daemons, and deal with much more of a mish-mash of init and conf stuff.

Mind you, Debian is good if you want a server that's not cutting-edge, that's real stable, and that doesn't do much that's fancy. But Gentoo is less trouble and performs better if you have clients who you've sold on using today's technology, rather than that of several years ago.

Oh, and desktops in particular run much better when the stuff is compiled for your specific hardware

and the feel of responsiveness is a major factor in making power desktop users feel comfortable and happy

There are quite a number of such proposals. For instance...

• Designated Senders Protocol: A Way to Identify Hosts Authorized to Send SMTP Traffic
• A DNS RR for simple SMTP sender authentication
• Repudiating MAIL FROM

...among others. The Internet Research Task Force Anti-Spam Research Group (IRTF ASRG) currently has a sub-group specifically dedicated to the unification of these proposals. This is a relatively recent initiative (only about a month old). You can find archives of the discussion at gmane.org.

Gentoo is really cool for producing systems optimized exactly for your system

Or not, as the case may be.

They still haven't fixed the problems in the framebuffers. Anyone know why this is so low priority?

As far as I understand, there is still a significant body of new framebuffer code that hasn't been merged to Linus' tree. There is a message from the framebuffer maintainer on the Linux framebuffer development list saying that the merge will happen, quoting him directly, "Very soon. I have new software cursor code that I'm debugging right now. This is the only thing holding back the syning."

It would appear its not a newsgroup but a webboard?

And now, would somebody please mod me off-topic? :-)

It was announced on the Toronto Linux Users Group as an open talk, so anyone is free to attend AFAIK.

nntp//rss is a nice tool for reading RSS feeds with your favorite newsreader.

IMHO this is a good replacement for (mostly) read-only mailing lists: it is much easier for the average person to set up a web forum with RSS than a NNTP server or even a (self-hosted) mailing list.

For interactive mailing lists, Gmane is the tool of my choice.

Or you could get the mailing list to be carried by Gmane and browse the articles using a newsreader. No need for any of this newfangled RSS nonsense.

Daniel Robbins's reply reads like it was written by the Iraqi Information Minister...

You might want to try Gmane, a mailing-list to news and back gateway which has a quite useable web interface as well.

Of course it only carries groups that a) at some time subscribed there and b) do want to be carried, but for example open source projects are coverd quite nicely.

(based on this mail on ietf vrrp maling list)

BitTorrent isn't designed to make the original source unnecessary...it's designed to simply reduce load on the original source. Which it does quite well. The original source tends to send out around the bandwidth of a single upload at any one time.

This is not true, or at least is potentially misleading. BitTorrent's 'original source' is actually a peer setup by the .torrent's tracker operator (therefore seeding the BT network with the .torrent operator's bandwidth). That could possibly be the original source, but it's likely that its not. Such would not be the case (until movie studios setup .torrents themselves) in the case of movie trailer .torrents.

See this thread on the BitTorrent development mailing list for more information on the possibility of extending BitTorrent to fall back on a true original source if the number of peers is insufficient.

And how exactly do you propose to "inform the system that you are a real user"?

The answer to his question is, "By using TMDA, of course!". TMDA is an automated whitelist management program. I agree that manually managing whitelists is next to impossible, even at the individual level. But that's why TMDA exists, to automate that process.

And it's currently being tested on a large scale. GMANE is using TMDA as a mechanism of blocking spam for some 3500 mailing lists.

I wish I could rewrite the original question so that it was more clear that TMDA is an automated whitelist management program. Cuz I don't think the guy understood that. And he answered as if the question were suggesting that the ISP manage all their user's whitelists.

$.02

There are a number of things that you can do with mailing lists. But unfortunately, since there are so many different types of mailing lists with so many different configuration options, there typically isn't one single, easy to set up solution.

For what it's worth the TMDA documentation on the web site is pretty good. As for me, I tend to use TMDA sender addresses to subscribe to mailing lists. More details here. And, of course for anything more complicated than the docs can handle, there are the TMDA mailing lists, which can be accessed without subscribing through GMANE

Once you've gotten a little bit comfortable with TMDA, this is a pretty good reference for using it with mailing lists.

Good luck.

I've been using NetBSD 1.5.X for my workstation for about 18 months, and it's been great. Other than lpd, everything has been bulletproof. Previously, I ran Debian, and had periodic troubles with NFS and with ypbind, particularly when the LAN was flaky. No such problems with NetBSD.

While I'm at it, I'll plug gmane as well -- it's a lurker's delight!
