  1. Re:Multiprocessor efficiency on Linux Apps On Solaris · · Score: 1
    Linuxs initial target was desktops and smaller systems. Conventional wisdom is that Intel procs before the Pentium Pro could not do SMP, but that is an over simplification. They were the first that could do SMP easily. At least as far back as 1981 people were making "Supercomputers" out of Intel CPUs. http://www.computerhistory.org/VirtualVisibleStora ge/artifact_main.php?tax_id=03.04.07.00

    Linus thinks working on small, embedded, systems is perhaps more important then massive scaleability with SMP. That said: SGI has been producing massivly SMPd machines that run Linux for a long time. Prob with MIPS first, definitly with IA32 now, and with a heavily hacked kernel, but still Linux.

    I think Suns strategy of "ultraslows, but many" is much older then their "big iron" history. At least as far back as 32bit Sparcs, desktops, not to mention "workgroup" servers, were SMP capable. I dont know if it is realy a strategy so much as a necessity given RISC style processors. Of course, extending that argument, IA32/64 systems, compared to 370 arch IBM Mainframes are RISC too. And to scale up IA systems, you go SMP. Comparing Sun and Intel micro computers to a mainframe might be compleatly useless though :)

    "UNIX" means different things to different people. One definition would be something that contains ATT UNIX code. Another would be something that has a bunch of certifications. Linux has neither.

    But, the BSDs, and I believe even Solaris and AIX have a Linux compatability layer, or at the very least, "the GNU toolset", GCC, glibc, etc. Of course you wont beable to run IA32 binaries on a UltraSPARC, regardless of the compatability layer, but you could run IA32/Linux stuff on IA32/*BSD, or SparcLinux stuff on a Solaris box.

    I guess Im trying to say, given that lots of things can run Linux binaries, can cleanly compile Linux targeted sources, Linux + GCC + glibc may be a better standard to target then POSIX and whatnot. It is definitly more modern. Or to put things another way, UNIX is irrelevent, the question shoud be: can UNIXes ever be Linux?

    Having a 512mb card will allow for higher resolutions? WTF?

    Back in the day before video cards had texture memory, resolution was directly (root-icly?) related to your video memory. So a 640x480x16(bit colour) required 614400bytes of memory - a 1mb card. 1920x1200x32 would require 9216000bytes, or a 9mb card. This is the "frame buffer" - something writes to that buffer, and something else (a DAC) converts it to video. Some video cards had (have?) multiple frame buffers to allow for quickly switching, well, frames. There are other factors limiting resolution, of course - DAC quality, for one. But as most "frame buffer" only cards had upgradable memory, it is the memory that is the practical limit.

    Resolution is, well, fairly down the list of important qualites of a video card. It took me a while to dig around to get that resolution size (the largest that a Quadro FX 4000 will put out). Ever since about the time that AGP came out resolutions stoped being highlighted.

    I dont know how much "frame buffer" memory modern video cards have. I dont even know if it is just a segment of the main memory. Anyway, since a 256mb card has about 28 times the memory then is strictly necessary for driving a 1920x1200 screen, jumping to 512mb wont help at all.

    This is not to say that when 512mb cards come out they wont have higher resolutions. But it wont be because of the memory. Other technologies would also increase. Or, more likely, existing but expensive technologies would be put on these new expensive cards.

    You have a problem with different fields using "measurable" differently. In non-measurable sets, most non-set theorists would call that non-countable (which may or may not be a different theory. I remember "non-countable' from my discret math days, but never non-measurable. Beh). Many people would say that infinity is sufficent measurement (which is why I perfer countability to measurability).

    So far as Gib is concerned, "very big" is a measurement.

    True. And to add to the story, what they released as OSS diddnt even compile. The was a bunch of necesary 3rd party code in it that was removed. And they (Netscap) / we (outside developers (but not me)) spent about a year trying to work with the old code before they/we gave up.

    But the question is not if the current Mozilla codebase contains any Netscape <=4.x code in it, but if the release fo the 4.x code spawned a community that is still active. And that is a resounding YES.

    The thing about glibc, gcc, the Linux kernel, etc, is that you can take a course, or read a book, on libc, compiler writing, Unix internals. In theory, any upper year CS undergrad should be able to contribute to those projects. But there is no manual on writing a web browser. It is hard because it is new. The Mozilla codebase is huge. Contributing to the project thus requires a steep learning curve, and implicitly, highly motivated coders. A lot of that motivation comes from "because it is Netscape" and now "because it is Mozilla", beyond just "its an OSS web browser".

    Proof: "Friendly fire" incident in Afghanistan where Canadian soldiers were killed by the hands of a US Pilot. I put "friendly fire" in quotes because to me, it doesn't even qualify as that. Im prepared to accept combat deaths, even friendly fire ones. Anyway: the Canadians were on a known live fire range (and the Americans knew, even if that information didnt make it to the pilot and air controlers). The pilot reported fire, and was specificly told to hold fire. The fire was coming from a range well known to be used by friendly ground forces, including US Forces. He fired anyway, killing 4, wounding a dozen others. He claimed he was "under attack", but how a machine gun could threatin a F18 at 20,000ft, I dont know.

    Final end result: loss of 1/2 months pay for 2 months, letter of reprimand. In other words: exactly nothing.

    Two things:

    1. Password "hashes" are just that. Special types of hashes known as cryptographic hashes, but hashes none the less. They are not encryption in the traditionl sense of the word.
    2. It is, in a sense, possible to "break" a crypyographic hash. You simply put all possible inputs into the hash function and record their outputs. Indeed, a service that can return the input for a given crypt()ed output was recently featured on slashdot. It only worked over a limited range of possible inputs, but over the very likely range of inputs (alphanumeric, <10 characters, IIRC). Dictionaly attacks on password files are common, both by sysadmins and crackers alike. It is only a matter of determination (and storage capacity) to produce such a table for all possible inputs to crypt(), and its modern, stronger, friends. Now, you dont necessaraly have the "correct" input returned when you do such a search, but you get a correct enough input.. And for cryptographic hashes a correct enough input is correct.
