  1. Re:Flight on Build Your Own UFO · · Score: 2
    All of you are familiar with the concept that mass and energy are related; if mass can change space-time why is it impossible for energy to do the same thing?

    Noone has a problem with that. But size matters... especially if the said forces are tens of orders of magnitude larger than predicted by mass-energy equivalence (and in the wrong direction, I must add)

    If you have RC1 just use cooker and don't download the ISOs. For the next few weeks I guess it will be just bug fixes, not new features that might break so you are probably better off with cooker anyway.

    But model is unapplicable to GPLed software. Any such interface, config tool etc. is bound to be tagged as "derivative work" if it depends on the specific GPLed software to perform, consequently will be licenced with GPL.

    Are you telling me the defense industry doesn't care about the American people? That's it whole fucking purpose, is to defend morons like you.

    US so-called defence industry produces weapons for everybody around the world. Except for certain ultra-tech materials, production is not meant for exclusive domestic use. I don't have hard numbers to back this up but I would assume world-USA sales outweights USA only sales. Companies in "defense" industry are all more cheerful when they supply arms to both sides of a conflict. They can't be caring about both sides now, can they? This stiuations are rare but it is the US government who disallows the producers from suppling both sides.

    The latest rock I've been hiding under was mdk8.1, which is a pretty recent distro. I couldn't manage the system without falling to command line rpm at best, and compiling from source at worst.

    And no, I am not an old school guy who just prefers to compile cvs code. I really had to resort to command line all to often (dvd player programs anyone?)

    Compare comparable things : if you want to install something from the source under Windows ...

    Compare comparable things, the parent (and its parent) are talkin about installing applications on a platform. The usual way of doing that is next-next-next on windows, not source coed compilation, and the usual way for linux is..well.. I almost agree with your point there. Binary rpms installed thru a graphical packet manager is becoming the way to install apps, rather than compilation. We are not there yet, especially library installation.

  16. Re:QNX has far lower latency on Preemptible Kernel Patch Accepted · · Score: 2
    NT series are not really microkernel. The kernel has far too many jobs than those would be expected in a real microkernel, such as handling video and network.

    That said, I like the mix. Things that need all speed they can get are right in the kernel and nothing else is. That design wins over both pure microkernels and normal monolithic kernels for current desktop computers. I hope as computers continue to speed up, NT kernel evolves to a proper microkernel.

  17. Re:[PATCH] To fix compile error on UP systems on Preemptible Kernel Patch Accepted · · Score: 1
    It should be noted that this will lead to a compile error if you enable preemption but disable SMP.

    Are you sure that is OK? I was under the impression that preemptible kernel patch requires SMP locking mechanisms, and they in turn require SMP enabled kernel.

    It was 1k just like ZX81, but I'm not sure how much of it were actually avaliable to programs. It didn't have a separate video memory. My tightest program (which was a sprite engine) on a Z80 were 470 something bytes, I assume the pool control would take at least as much (math routines, timers etc.)

    Absolutely correct. I could do a similar thing with my 18 years old cpc464 (4Mhz Z80, 64Kb ram)under Locomotive Basic (default rom basic.)

    ZX80 probably will need a 16k expansion card, and hand translated machine code, but sure, it can be done.

  20. I thought about it some more... on Byte Benchmarks Various Linux Trees · · Score: 3, Interesting
    You should do something like starting with a large J (K*J comparable to but not exceeding total memory size) and read K*J pages without any preaccessing. E.g read values at offsets N,N+K,N+2K,...,N+KJ, then continue normal processing until you reach N+KJ. Repeat procedure with new N=N+KJ. This way you hint the VM that these pages are active, and should not be swapped out. K should be selected as large as possible, not exceeding a page boundary. Too large K will make fail to mark some pages as active, too small K will consume unnecessary processing time while hinting.

    If everything goes according well, your kernel should swap out and swap in exactly M amount of memory for each preaccesing pass, where M is the amount of data that does not fit in the main memory. So if you have total memory T, total data T+M and K*J size prefetch, total swapped data per whole process would be M*(T+M)/(K*J).

  21. A suggestion on Byte Benchmarks Various Linux Trees · · Score: 1, Offtopic
    I can't answer the kernel related part of your question, however a possible workaround is forcing future reads from active pages by preaccessing them. E.g, before starting on processing [N,N+K) cluster, read value(s) of N+K, N+2K, N+3K up to N+JK and write them back. For a suitable K,J pair, you should experience linear performance drop. A K=8000 and J=1 sounds reasonable to me.

    &ltspeculation> AFAIK kernel uses a hairy buddy system (but I did not check that myself), if that is the case, not whole memory is accessible in an arbitrary allocation sequence. So your analysis of exceeding 1024Megs of memory by less than 10 Megs is incorrect. You have to allocate progressively smaller page sizes that follow fibinocci(sp) series (or something like that, see your local kernel hacker for more info) if you want whole your data in memory. &lt/Speculation>

    An afternoon with Perl and Gnuplot would probably be quite interesting with that data. It would be sobering too, especially if logs include some key phrases from the comment (like "I MS because", "Nuking them to ground is not a sane idea because") Many people think editor moderation is a problem. I think moderation is the problem and user moderation is the worse part of it.

    I always got the impression the IP-banning business was more to do with how many negative mods you recieved in a short space of time...

    Yeah, it has nothing to do with AC posts, I was just quite fond of my 42 karma so posting as AC and planning to continue that way. Anyway, out of my five posts -including this- to this thread, two has already been -rightfully I must add- modded down as offtopic. I expect these three will soon follow. That is plenty of down moderation in a short amount of time but I don't know how much it really takes to be banned.
