Blender is a modelling/animation studio. You point'n'click to make 3D models. povray is a renderer, it reads a file that describes what to render (all objects/camera/lightning/texturing etc.), and produces an image for you. That file might very well be created with blender,and
a povray export script. It should be noted that blender has its builtin renderer as well, and builtin support for rendering via yafray. No builtin support for povray yet though.
So, are we having flamewars again about the Blender UI ? Knock on wood if it doesn't happen.
Anyway, before people start bitching about it, please download the manual here(Vol 1) and go through the tutorial of creating your first animation.
Once you get to know how things works, its logical, and a breeze to use. Sort of learning the power of vi or emacs, it's right there, you just don't see it at first, and you have to learn a few basics to get started
Now, how many Suns are there out there ? Billions in our galaxy, and many many galaxies. So we've discovered 100 of them have planets, and just a few tenfolds more have been scanned for planets. From that one draws the conclusion we are alone !!??
The "current technology and techniques" link is in that context also very interresting, as we at the moment don't know how to detect earth sized planets.
I think a bit more science and research is needed before one draws the conclusion that our solar system is genuine. Heck, even a solar system similar to ours for 1 in 100 millions solar system would indeed be interresting.
Agreed. Scientific publiations shouldn't have any financial base, this is science, it should be done for the benefit of all. Not for the benefit of someones bank account.
Well, _lib_png have many, many jmp like instructions, they're called function calls, and if you manage to overwrite the return address on the stack, you can make it jump anywhere, like the code you injected. Hopefully it's just the stack you can overflow, most of us should run with a no executable stack theses days, no harm done(well, it probably crashes.. )
And how many PHP sites/scripts dynamically generates.png files ? Quite a lot I'd think, so, webservers might be vunerable, but it seems like a longshot to try to inject something to such scripts.
You can compare the sources of NetBSD and OpenBSD to find much of the same security fixes. (Or just look at commit messages).
As for the speed issues, I've ran some of our telecom applications on the OSs, speed(piping lots, I mean LOTS, of data through several processes, spawning many short lived processes, and file IO) sucked on OpenBSD. The guy at http://bulk.fefe.de/scalability/(and read where it says NetBSD-CURRENT also) did the same. NetBSD 1.6.x somewhat suck in some cases. Latest 2.0 rocks.
Well, speed. OpenBSD is committed to secuity, not speed, and it has many rather slow internal algorithms.
I'd suggest NetBSD. It too cares greatly about security, and imports lots of fixes from OpenBSD. And it's slimmer than FreeBSD. Not to mention solid. I've many times managed to make both OpenBSD and FreeBSD go mickey, but have yet to crash NetBSD.
You know, there's a diffrence between living in such a hostile environment and evolving there. I hardly think the life living under harsh conditions in iceland evolved there. It rather gradually adapted from things living under much 'friendlier' conditions. Conditions that might never have been present at Mars, allowing life to start at all.
For one, fast ethernet cards are nice for clusters, not only because they can transfer lots of data between the cluster nodes, but just as much because of latency. Think e.g. MPI programs passing lots of small messages between processes; the faster the better.
Setting aside the license diffrence, could anyone objectivily give a brief summary on the current status of Xorg vs XFree ? (e.g. what's better/newer/fixed in one vs the other), and are there any future goals that differs greatily between them (what's planned for Xorg, what's planned for XFree)?
Does Xorg do configuration any diffrent than XFree on FreeBSD ? I see no diffrence on the configuration on the Xorg linux distros I've tried. (Then again most linux distro also provide their own high level config tool as well, no sweat.. )
Well, if you look at the kernel changelogs, e.g. linux.bkbits.com:8080/linux-2.4 and linux.bkbits.com:8080/linux-2.6 you'll see that SGI already contributed alot.
No. It's not about 200 years of uptime. It's about the applications and the data. As mentioned in the article e.g. gouvernments need to track many many things, such as personal records for the citizens. Having to consantly upgrade such a system, train people to use that software every few years would be a major effort, and cost a lot. If you can just migrate the applications and data to a new platform/hardware as the hardware becomes obsolete/faulty is ok, as long as the applications continue to do their job.
And I suppose you cold explain why, except making it easier to access nvidia specific features ? Both the OpenGL API and ABI(on linux) are standardized, so it doesn't matter whose headers you use, as long as they are for the OpenGL version you want to use.
Most seems to use 4kb as the standard page size, though pentium processors supports 4Mb pages as well. Some OS's take automatically use of that for certain conditions, others e.g. linux, let you in use them by explicittly saying so.
It's a point, but an email spreading worm will have no problem doing it's thing running as non-root. And most the interresting things on my box are my own files, created by me. A virus/worm running with my privilegies could do big damage. The OS one can always reinstall, not peoples files. (No, people in general doesn't do backups yet..)

So.. basically, set up a NAT or proxy server rather, and let the internet users of the world use that (+IPSec)!?

Quite a lot I'd think, so, webservers might be vunerable, but it seems
like a longshot to try to inject something to such scripts.
And if you look ad SUS, you'll see that it requires a whole lot of posix features.
Crap, to late here now, parent poster wasn't askin *me* to elaborate.
Oh well..

Uhm, it's not a theory, its already done. Many, many times, in many games.

Oh, you didn't see the sarkasm ;p
So the lifeforms we already know that don't need oxygen nor sunlight doesn't really exist ?
Well, you only need a 32way pSeries p690 to compile the linux kernel in 4.8 seconds. Nothing fancy like beowulf or distcc needed.
