May I ask what a "variant symbolic link" is?
www.eFax.com are spammers
Support for variant symbolic links is exciting. That makes it really easy to support 64/32-bit modes on Opteron systems. Similarly, it makes it easy to support variant ABIs for (e.g.) C++ runtime environments without encoding ABI versions into library names, but do look out for combinatorial explosion...
I know it's a troll but BSDi didn't die. We sold BSD/OS to Wind River and continued as iXsystems / Offmyserver.

I think this project is a good model for how large projects should be handled.
They published their design and a roadmap for implementing their design. This
makes it easier for a lurker who is watching the project to actually jump in
and contribute to it.
At least, it seems that way in theory. Anyone have any idea how responsive the
community has been to this project?
*sigh* back to work...
Uh, anyone want to give an idiot like me a concise and clear reason why DragonFly BSD is superior to the other BSD variants? What specific applications is it more suited towards?
No, I'm not trolling, but thanks for asking.
Karma: Chevy Kavalierma.
I've been using it since february, and let me tell you, it's great! It's fast, and generally stable (between major changes, it is a prerelease OS don't forget!), and it runs legacy Linux and FreeBSD binaries at native speeds.
;^)
And it is being redesigned at it's core to be a clustering capable operating system (although this is not in just yet). Soon it will be able to run user mode drivers, greatly enhancing the stability of the system to levels that no other current OSS project can boast (and still be telling the truth
This truely is what a modern UNIX-like OS should be!
Way to go Matt and the rest of the DragonFly team!
message passing == micro-kernel ?
Your CPU is not doing anything else, at least do something.
Good news, everyone!
Turns out that *BSD is stronger than ever!
According to an Inernetnews article, Netcraft has confirmed that *BSD has "dramatically increased its market penetration over the last year."
There has been a steady increase in *BSD developers over the past decade.

Enjoy!
This is way too easy:

"As personal rivalries took precedence over a quality product, BSD's codebase became worse and worse. As we all know, incompatibilities between each BSD distribution make code sharing an arduous task. Research conducted at MIT found BSD's filesystem implementation to be "very poorly performing." Even BSD's acclaimed TCP/IP stack has lagged behind, according to this study.'
Hmm, can you say that about any Linux or Window system that is completely compatible between releases? Or any software for that matter?
Lagging TCP/IP stack? Degrading? Break out your OS and compare. Please put your money where your mouth is:
NetBSD Sets Internet2 Land Speed World Record
http://bsd.slashdot.org/article.pl?sid=04
"Problems with BSD's codebase were compounded by fundamental flaws in the BSD design approach. As argued by Eric Raymond in his watershed essay, The Cathedral and the Bazaar, rapid, decentralized development models are inherently superior to slow, centralized ones in software development. BSD developers never heeded Mr. Raymond's lesson and insisted that centralized models lead to 'cleaner code.' Don't believe their hype - BSD's development model has significantly impaired its progress. Any achievements that BSD managed to make were nullified by the BSD license, which allows corporations and coders alike to reap profits without reciprocating the goodwill of open-source. Fortunately, Linux is not prone to this exploitation, as it is licensed under the GPL."
Please back up your facts
1) Sun created SunOS (based on FreeBSD) and what have they done: Release NFS and a ton of other tools to the community.
2) Apple gives the code back to the community (less the grapical interface).
"The failure of BSD culminated in the resignation of Jordan Hubbard and Michael Smith from the FreeBSD core team. They both believed that FreeBSD had long lost its earlier vitality. Like an empire in decline, BSD had become bureaucratic and stagnant. As Linux gains market share and as BSD sinks deeper into the mire of decay, their parting addresses will resound as fitting eulogies to BSD's demise."
Jordan Hubbard works for apple and he is extensively involved with with Darwin and their ports system. Which in my preceeding statment shows that they give back to the community.
All your adhoc statement have no foundation. I have backed up my statements, please back up yours.
You're pushing buttons. The initial question was answered fairly
For the record, I've found the DragonFly user and developer community to be the most helpful I've ever encountered online, but if you're not even going to quickly go over the information on the web site, they are under no obligation to repeat what is freely, and publically available information, that has been there right out in the open from day one.
I've asked my fair share of dumb questions, but I've also read the web site. This should come as common sense, but I guess that I am greatly overestimating the mental capacities of the general Slashdot population (yourself included).
Mike Smith also works for apple now.
There's an article on daemonnews about it, under "BSD at Apple"
Dipshit.
ProPolice enabled by default, replacing of unsafe string functions from many ports, systrace, etc.
Apple gives plenty back to gcc, the GPLed compiler upon which they rely.
They don't give a lot back to FreeBSD though. If you think they do then you obviously have no idea.
W^X, ProPolice, randomized shared library loading. All of these happen to ANY program compiled from source, with or without code auditing, and make overflows pretty damn hard to exploit, probably impossible.
Linux doesn't do any of those, since it's just a kernel. Some distros might hack in something like PAX, but its nowhere near as pervasive and as well tested as on OpenBSD - it takes toolchain support for randomised shared libraries, and OpenBSD also fixed a lot of bugs in Propolice while integrating it, showing noone else has seriously tried it to use it before across multiple architectures.
Oh I didn't even mention stuff like StackGhost on sparc...
Linux does "W^X", aka non executable mappings in non-leet speak
/usr/libexec/ld.so /usr/lib/libtermcap.so.9.0 /usr/lib/libc.so.30.3 /usr/local/bin/bash /usr/libexec/ld.so /var/run/ld.so.hints
... except via PAX, although I'll be glad to be corrected. Of course, not many major distros actually use PAX or Propolice, where OpenBSD delivers tested binary packages for 10 (or whatever the current number is) different architectures. I'm not interested in security where I have to patch and recompile my entire OS.
No it doesn't. W^X ensures that there are no pages in a process's address space which are writable and executable and separates them. Not just a non-exec stack. For example on i386:
0250B000 24K read/exec
0280A000 4K read/exec [ uvm_aobj ]
06B04000 188K read/exec
0861F000 508K read/exec
1C000000 348K read/exec
2250B000 4K read
2250C000 4K read/write [ anon ]
(trim)
7EB90000 4K read/write [ anon ]
865FF000 12K read
CDBFE000 28672K [ stack ]
CF7FE000 4040K read/write [ stack ]
Notice how the exec mapping stop, and the write mapping begin. This means on i386 the segment registers can be used to enforce read/write/execute - you dont need a new processor with per-page NX (although that works as well of course).
It does randomized shared library loading, and this doesn't require toolchain support in Linux, probably because its design is cleaner than OpenBSD's
Vanilla Linux doesn't
Linux can quite easily be built with propolice, and it has a very fine security infrastructure with SELinux. More advanced than what OpenBSD has.
Very funny. The average sysadmin understands the UNIX security model. Not many understand the insanely complex SE Linux thing.
Linux does a lot of things better than OpenBSD, but really, security just isn't one of them. I always regret posting to Slashdot to try to correct some of the cluelessness here, so this will be my last post here for a while again.
It is true that the new code they wrote is distributed under Apple Public License, which isn't as free and short as the BSD license.
I saw "continuation of FreeBSD 4" and got excited, but then I saw "GCC 3.4" and got disappointed.
Give me a compiler that doesn't require a Quad Xeon to compile KDE in under a month, please!
it seems the moderators are too busy modding down people they disagree with to be bothered with posts like the grandparent. oh well. maybe they can at lest mod this down since it points out how much the mods suck today.
i like to browse at 0 so i can read Anonymous comments because usually they are about as insightful as comments by people with karma. (i guess i should see if there's some way to disable the karma bonus modifier in my viewing preferences). anyway, usually browsing at 0 works because posts such as the grandparent, as well as GNAA and BSD is Dying trolls get modded down almost immediately to -1. in conclusion, i'd just like to mention once again how much the moderators suck today.
moderators, you all suck today.

MORTAR COMBAT!
Hahah! Beat you twice.
Hahah! I pounded your mom three times.
Well I actually didn't. I just said that to provoke a response and obviously have absolutely no proof because I am lying through my teeth.
But I'm sure you would never do something like that.
Heheh!
Very true, and very misunderstood, judging by the people commenting on how bleeding edge it is.
It's seemed to me that once the messaging system is fully in place, DragonFly will have an incredibly simple, extensible, and stable API on which to build, and that a number of features that both Linux and FreeBSD now have will be much simpler to implement on DragonFly in the not too distant future, and will end up being far less hackish than the current solutions.
It's unfortunate that supposedly technically competant people get so enthralled by buzzwords and hype that they will cling to technologically inferior solutions or ideas, despite the fact that it is both relatively painless for them to adopt or otherwise incorporate the newer technology that's free to boot.
In the end though, while Linux will require corporate hand-holding (funding, marketing) and hand-me-downs (code ripped from proprietary UNIXes and welded into Linux) in order to keep growing, DragonFly will be able to stand well enough on it's own, with the developers being able to add new functionality easilly enough on their own time and on their own terms.
Perhaps a decade or so from now, Linux will be in a similar position to the one Windows is in now, and DragonFly will be there to provide a much needed alternative.
PS: use portupgrade -PP to get binaries as you don't seem to be very familiar with Unix.
Way to bite on a blatent troll you fucking retard.
The problem with a 'startup' is that if you decide to rely on it and they disappear down the road, you are screwed..
At least with the "big 3" you can be reasonably assured they will be around in another 10 years..
Not to slight what the dragonfly people are doing, its really great... But its still in its infancy..
---- Booth was a patriot ----
Why would they? "Here's your code back; by the way, now it's a microkernel."
English is easier said than done.
Most ammusing post ever. Man, you should write for Slashdot. The Linux crowd will love you as they love this sort of garbage! Way to go!
Matt Dillon put RC2 on the download page.
It's also available via BitTorrent.
...the BSD is the only pray to stand ground to server predator, the Slashdot!
Soar grapes!
