SGI's B1 code
SGI has a site with some sample code and documentation about implementing a B1 secure system over here which may be of interested in this conversation.

B1 Sample Implementation
I recently linked the web page for SGI's B1 sample implementation on OSS. Here is the URL http://oss.sgi.com/projects/ob1/. You can find some source for a sample implementation.

C2 for Linux is underway
SGI is supposed to be working on C2 certification, which they're hoping to get into the mainstream so that pretty much any distro that wants it can be C2-certified, and also B1 or B2, I forget which (whichever one is legal to export). They are doing this specifically because they have reason to believe they can sell Linux to the DoD.
Unfortunately, I can't find anything confirming this on their site -- this is information I picked up at the recent SGI "Linux University" travelling show. If I recall correctly, and they manage to keep to their projected timetable, we should see the C2 Linux become reality sometime later this year, and Bn in 2001.

IBM has done it again
Well isn't IBM a wealth of cool new things. Sounds like it will be a cool computer(s?). Also if you want to see a computer that can go to 1 teraflop, click here. Ehh ehh, sorry the computer is making me horny. Also I know a guy who knows a guy that wants to know what a Beowulf cluster is. I can't explain it very well so could you tell me what to say. (that sounds authentic, right?)
Oh well, Have a nice day all,

Wide-aspect, all-digital TFT panels are the futureFor the last year, I've been using the SGI 1600SW 17.4" widescreen. It's not perfect, but it's not far from perfection either. My only complaint is that it uses a nonstandard digital video interface, and the #9 TTR-4 video card that works with it is not well supported.
Why do I love it so much?
- No eyestrain, ever.
- Four easily-readable xterms/rxvt's/etc. on the screen at once. 1600x1024 is a wonderful resolution.
- Ok, I admit, it makes my co-workers jealous.
:)
I have an expensive Mitsubishi 22" flat CRT at home, and even though it supports similar resolutions, it isn't nearly as useful. I have to run a much lower resolution than the monitor supports to keep the text sharp, even with top-of-the-line cables and video cards. And what a desk hog!
I can't wait until 24" panels become affordable...

Re:Rendering under Linux
Maya is more than just a raytracer. It is a complete modelling / animation / rendering / dynamics / visual effects package.
You can read more about Maya at http://www.aw.s gi.com/entertainment/solutions/about_maya/index.h
t ml.Raytracing and vector drawing are very different. Here is a grossly oversimplied summary: In raytracing, you loop across each pixel in your image and determine the colour by following the rays of light backwards through the 3D scene. Raytracing naturally allows you to model things like reflection, refraction, translucent object, fogs and a host of other cool effects but it is computationally expensive. You typically do raytracing if you need photo-realistic picture quality. Vector drawing done by looping over each object in the scene, transforming the vertices, and drawing a transformed version of the object. This is not very flexible but can be easily implemented in hardware making it very fast. You typically do vector drawing when you need to render an image very quickly (eg. in a computer game).

Re:SGI 1600SWI actually have a SGI-320 with the flatpanel display. It worked fine under 3.3.5 with the fbdev server, but I haven't tried it. You might try SGI's linux site for more information. At the very least you can download the configs to use the panel with 3.3.x and you can probably work something out form there.
On a side note, now that you mention it, I am eagerly awaiting the time to set up 4.0 on the 320 and see if it works for me!

Starting points.A good starting point is probably the Multi Disk System Tuning HOWTO. The various RAID HOWTOs may also be informative.
EXT2FS does not have much problem with file fragmentation. Like most Unix filesystems, it automatically reuses all empty space and tries to keep files/directories together.
XFS does look interesting, and it should at least reduce restart time.
Notice that on a server you can reduce file system updates by putting files which are rarely updated on read-only filesystems which are separate from the often-updated ones, reducing the partitions which need to be checked.
Of course, maybe you should also start by considering how much better anything else is when compared to what you're presently using. NT needs defragmentation, and crashes often enough that restart time and disk recovery are great concerns.

Re:High-Availability Linux Project
Wouldn't it be better to put more communty effort into a [...] GPL'ed solution instead of trying to port Irix's existing product and possibly getting a half-baked license?
I think SGI have been quite good about licenses generally. Their journaling file system, XFS, is released under the GPL, as is NFS 3 and probably more of their stuff. So let's wait to see what license they use here before assuming it will be the sort that Sun try to fob us off with. -

Re:MSDN for Linuxi disagree. there really _is_ a need for something like this. i'm offline so much of the time, in a cafe, on an airplane, etc, that if i need to search any and all linux documentation, i _have_ to have it with me. as the previous author noted, there are other motivations for having a complete copy offline too, such as expensive connections, and i'm sure there are others.
i'd like to see an iso image of the ldp, and all it contains, have it be searchable, indexed, and running locally on a live webhost, etc.
one completely exellent tool that i've used for years which does this, but for IRIX, is the IRIX developer's toolbox. there's an online mechanism, and a mirror which you can get cds of, and use offline. excellent tool for IRIX devrs (and lots of code for stuff like opengl too). check out:
i'm curious if other slashdotters who work offline would find a tool like this (say ldp on a cd) useful.

``Unstable''?
What exactly does ``unstable'' mean? Or, more accurately, what does ``stable'' mean? The 2.2.13 and 2.2.14 kernels (supposedly ``stable'') have rather nasty inode leaks. And 2.2.11 and 2.2.12 had a memory leak (which is why SGI based their SGI Linux 1.1 kernel patch on 2.2.10). Hmm... Looks like stability ``leaves somewhat do be desired''.
Featurefulness perhaps? Well, one patch I find extremely useful is the ext3 filesystem. (Now that seems stable enough, despite the frightening version number: 0.0.2c) But Stephen Tweedie hasn't finished porting that to 2.3.x. Another useful patch is the international crypto patch, and that doesn't come for 2.3.x... Or the Openwall security patch: ditto. Hmm... Looks like I'll stick to 2.2.x for some time. (And, no, it isn't exactly ``warm and cozy''.)
I'd like to try the 2.3.x kernels by using User mode Linux, but so far the only thing I've got from that is a core dump.
Sigh...

Re:Some Possible Problems?
I have a friend who used to work on the virtual environment models for a driving simulator. ...noted problems with depth perception and motor skills after using the headsets. They've even had to limit usage to make sure employees can drive home safely.Four huge video screens (one at the back for the rear-view mirror), force-feedback steering, completely enclosed car, all powered by an SGI Onyx. They were going to use it for driver training.
Two very disturbing effects I wanted to share:
- Hit the highway [maaaaaarm, mAAAAAARRRRM], get it up to 220Kph (about 125mph) [Ruummmmmmmm] with a full load of passengers, then open the driver's side door and walk out. Whoah, trippy!
- If you've ever driven through Melbourne, you'll know the tram stops here have big yellow concrete ramps in the middle of the road, to protect waiting passengers from speeding cars. In the simulator, the code for collisions with the ramps was never finished, so you could drive through them. My friend (who was often testing the driving simulator) had great difficulty when driving in meat-space... convincing himself that the ramps were real...

SGI, please port Open Inventor to Linux

I still think it looks like SGI IndigoMagicAs I have said before....
If you have ever used a SGI Indy running Irix paired with that amazingly *ahem* interesting 4DWM desktop windowing environment the dynamic resizing of icons should be familiar to you.
I used to have access to one back in the mid 90's... whoa... that sounds cool.
I know when I took people by the lab to see it they would immediately go "COOL!!!" when they saw the scrolly thingie make the folder icons look bigger then smaller then bigger then... you get the i dea.
It's no wonder SGI's never caught on... it must have been the amazing easy to install no issues approach to software they have always used. I know I am not alone in feeling this way.

Re:Why this caveat?They have an answer for your speculations in their FAQ. For example: 2) SGI has their own motives for not letting others know the dynamic code generation secrets due to political reasons, though I cannot fathom what they'd be.
Dynamic assembly code generation for rasterization is not yet included, making software rendering performance slow. The geometry path assembly code optimizations which we ship to our commercial licensees are actually owned by other companies, so we don't have the rights to place them under an open source license. We will work with the companies involved to try and free up these components.

Re:sgi still won't be able to support itself
Ahem...
SGI turned a profit in the second quarter, if you read their web page.
Sure, it's because their restructuring charge was smaller than expected, but they still would have only lost a million dollars.
I suppose the important question is "Will it continue?" But that's for the stock analysts to sort out.
Personally, I think you're wrong on MIPS and Irix.
WRT the pricing model: If you want a cheap SGI, buy one of their remanufactured, older, and slower Indigo2s. Besides the slower processor, they're probably as good as Sun's Ultra 5s for $1000 less!
But SGI doesn't really exist to sell cheap, slow hardware. ;-) -

So it does:
What's missing from the current Sample Implementation? ...Dynamic assembly code generation for rasterization is not yet included, making software rendering performance slow.
That looks like a fun project. I assume this is the time honored hack of assembling code on the stack and branching to it, to cover all the lighting combinations without having 10,000 different inner loops.
The geometry path assembly code optimizations which we ship to our commercial licensees are actually owned by other companies, so we don't have the rights to place them under an open source license. We will work with the companies involved to try and free up these components.
Go get 'em :-) Obviously it's in their interest to throw their stuff into the pot if they want to sell cards to 10,000,000 penguinistas.

Re:But OpenGL won't be open-source
I don't know how you could consider it not open source; please read the license.
Being "GPL-compatible" is a red herring. Mesa is now under the X license, and the Sample Implementation we just released is under a license designed to be compatible with the X license, in both cases for the same reason: so that the code can be incorporated into XFree86. XFree86 is, if you will, "GPL-incompatible" and that is a conscious decision by the XFree86 project.

.Mips is _not_ dead. In spite of the fact that MIPS was spun out, SGI retained the high-end design teams within. SGI has announced and shown the roadmap for Mips chips and technology for computers (versus the embedded world) that currently runs through 2006.

Re:MesaGL
Well, Mesa is not really 100% OpenGL 1.2 compliant. If you read the frequently asked questions you will notice that they are talking about the possibility of merging Mesa with their Sample Implementation. I think this would be a very good thing--It would make a fully compliant implementation, while maintaing the good parts from Mesa.
-
Now I'm impressed
I'm amazed.
That's all there is to it.
For years, SGI has treated GL and then OpenGL as one of the crown jewels. Even the API exposed a lot of their hardware architecture. The source of OpenGL was what made those amazing framebuffers go. Now, to see Kurt Akeley going on about open source and releasing source to Open GL....
As far as I'm concerned, this is definitive proof that SGI has become as much an open source company as Red Hat or VA Linux.

You can find more information about this here on SGI's OpenGL Sample Implementation. The frequently asked questions are available here.
The page mentions that this OpenGL implementation will be released under a very open license. They will be using the SGI Free Software License B. Another interesting thing mentioned is that in the long term, the sample implementation and Mesa might merge together. It will be very interesting to see how Mesa will continue to develop.
I'm glad to hear that SGI released this, because OpenGL was one of Linux's weaker points, since Mesa isn't fully OpenGL 1.2 compliant. Way to go SGI! -

Another interesting thing mentioned is that in the long term, the sample implementation and Mesa might merge together. It will be very interesting to see how Mesa will continue to develop.
I'm glad to hear that SGI released this, because OpenGL was one of Linux's weaker points, since Mesa isn't fully OpenGL 1.2 compliant. Way to go SGI!
