OpenGL 1.5
·
· Score: 5, Informative
I wonder when these will become standard (not just as an ARB extension but as an ARB required feature). Hopefully in 2.0? It will save a lot of calls, at the very least--just check the version number of the GL implementation, no more searching extension strings...:)
That the reason that it was called 1.5 and not 2.0 is that the shader language didn't make it to the core specs, and that they plan to promote it to core specs (and release 2.0) soon, possibly even in the next ARB meeting in september or the one thereafter.
Here is the quote:
The result was a simple majority of non-abstaining YES votes, but not a supermajority. Interpretation of this vote required some care since final spec approval requires a supermajority vote, while consideration of features for the final spec requires only a simple majority. Because the NO votes were strongly held, we expect that trying to approval a core revision including the shading language would carry extremely high risk of failing to approve the spec. We will therefore not include the shading language into the core at this time, but instead drive a new core version as soon as there's more experience with the extensions, perhaps as soon as this fall.
As previously agreed in the marketing working group, we will call the new core revision OpenGL 1.5, reserving OpenGL 2.0 for a future core revision including the shading language.
While I can understand his reasoning, the fact is that most software on the PC runs under VC or Intel's compiler.
Not so, the intel benchmarks are usually done with a special intel compiler suite that only intel uses, which assuredly contains every cheat iand other shortcut in the book
And do you not think that intel or others don't pull similar tricks ? Just watch AMD and Intel fight over wether HyperThreading speeds or slows the P4. Also, it is well known that intel uses special intel optimized compilers to run benchmarks and i am sure they also used the same malloc tricks as apple used, it is standard industry tactics when benchmarking.
Actually, if I could get a Linux laptop that did everything my Tibook does, I would. But there aren't any and most of the x86 laptops out there are trash.
Well, there is nothing stoping you from running Linux on your Tibook, you know.
Well, it may work, but not with every quicktime movie. I tried viewing the TTT trailer, which works fine under quicktime under windows, it works fine for a few seconds, and then the image freeze and i only get the sound. It is the same in both mplayer and xine, so i think the win32 codecs are not working all that fine.
I lost my time this weekend updating my GNU/Linux Debian system to GNOME 2.0...
Are you sure ? There is no such thing as gnome 2.0 in debian right now, the packages you upgraded to are either the final 2.2 ones or the release candidate ones.
Just look at the POP reference design [openppc.org] they made a few years back. Nobody I mean Nobody ever produced a single board. The fact that they used a virtual non existant Northbridge didn't help.
Well, i know of at least 4 motherboard you can buy today based on that design, the Mai Logic Theron boards, the AmigaOne, the Terrasoft boards and the Pegasos.
Actually, the first 3 are the same design, while the pegasos is a microATX board. It is real tiny, and runs without a fan, which is rather nice (and yes, i have one just beside me, need still to find a nice microATX case for it though).
The link is: http://thendipo.alias.domicile.fr/fr/pegasos.ht m
And for the Mai logic boards: http://www.mai.com/products/teron%20cx.htm
Don't bother the price on this site, these were prototype reference designs, i think.

IT toke time, but today you can buy a motherboard based on the MAI logic chipset, which is in turn based on the IBM POP specifications. Sure they are more expensive than comparable i386 solution, but this is only the begining and they are not yet produced in big quantities.
I have a 600MHz 750Cxe wich runs without a heatsink. The 750Fx runs even cooler, the 750Cxe consums 6W @ 600MHz, while the 750Fx consums 3.6W @ 800MHz, so i guess it will still run without heatsink at 1GHz.
Also, for the price, the biggest part of the price is coming from the limited quantity production of motherboards and other such parts, at least if you are buying from someone else than apple.
And i uploaded a debian package of it, it got accepted into the archive this morning, so it will probably be available starting tomorrow or even this afternoon.
That may be true for a particular contest, but if you look at the large picture, and examine the winners of the past contests, then you may see that the same progamming language come on top regularly.
And last year was a XML parser or something such i think, and the year before, it was a raytracer, so these are rather different tasks, don't you think ?
Well, i don't really know much haskell, but ocaml is used in many 1st year mathematic/CS university course in france, so there may be many pedagogical material out there (but then possibly in french).
That said, both language come with good tutorials, so i would have a look at both to see which one suits your best.
Ocaml is rumored to be faster, since it is using strict evaluation as oposed to the lazy evaluation of haskell.
The G3 and G4 are the consumer PowerPC chips. IBM are pushing it - they have the POP motherboards, which are slowly starting to appear now, and with a SOI
Well, the POP board have just yet been completed, and there will still be time before they go into production. so we will still have to wait some time before you can really buy some not to say at an affordable price (well they cost around $1000 for 1000 pieces, if you decide to make them yourself)
tarted sndconfig via. XTerm. Gave me a warning that it shouldn't be run in graphical mode. I ignored the warning but note that there is no easy way to boot into text mode after you have asked Xconfigurator to boot into KDM. (you have to change the runlevel.)

But the reality is that all the software i use has been built with gcc, so it makes a good testcase.
The true benchmark would be to cross compile a m68k kernel on both machines for example, or the whole mips xfree86 tree.
Also, i don't see you pointing out that intel and other x86 players have made big gcc contributions too.
And do you not think that intel or others don't pull similar tricks ? Just watch AMD and Intel fight over wether HyperThreading speeds or slows the P4.

(but, okay, the Gnome file selector, ehm, needs some improvement too.)
Which didn't make it in 2.2, but is scheduled for 2.4.

Average power consumption at 1.8 GHz is expected to be 42 Watts with 1.3V Vcc.
Well, The same hapens with galeon.
Don't know what it is also. It only happens almost at the end of the download though.

Right, it comes from the French word I assume.
In french, libre also doesn't have accent.

Notice that nothing is stopping you to use an old plain Xterm as your terminal.

Well, apple is rumored to have contributed to the ppc optimization of gcc, after all, they are using gcc to build macosX so this make sense
Couldn't one also implement an MMX-type thing, where in one operation you'd add two
64-bit numbers in parallel, or perhaps
4 32-bit numbers
Where have you been, altivec does just that (at least for the 4x32bit stuff).

what is wrong with Alt-Fn ?
