  1. Re:May I be the first to say... on IBM Plans to Open the Cell Processor · · Score: 1

    Hey smarty, Is his point valid or not? If it is is there a prevision to run modified gpl'd code by choice or not? If we would be totally locked down by this, I'd be inclined to avoid the thing for general use too. I might buy it for my kid as a simple ps.

  2. Re:Length contraction? on Excursions at the Speed of Light · · Score: 1

    By Ray tracing, I mean tracing the path of a 'light ray'. I am asking how a physical contraction of the camera would alter the explanation on the web site. I am not sure if the contraction is only in the direction of movement. If so, it would seem to not counteract the distortions of the simulation but might exacerbate them. If, on the other hand, the physical contractions are on all axis, then it seems to me, the distortions due to the shorter time for a photon to travel from the pen hole to the film plane would be offset by the shrinking of the film plane itself.

  3. Re:Length contraction? on Excursions at the Speed of Light · · Score: 1
    If I correctly recall, special relativity and the
    Lorenz contraction say that the observer would
    acutually contract.


    So, I suppose, because they dropped the speed of
    light to 30 kmh, the simulation is valid as it
    only
    has to deal with the relative position of the camera
    to the photons, providing you ignore doppler.


    If they were to simulate the camera moving at 95%
    of c, the camera would actually contract, along
    with all rulers an observer moving with the
    camera might use to measure.


    Does this sound correct? If so how does this
    physical contraction change the ray tracing of
    the simulation?

  4. copy/paste works pretty well on windows?? but but on Red Hat/Apache Slower Than Windows Server 2003? · · Score: 1
    Well, if you accept works as 'pretty well', I'll grant you that.

    The cut and paste in a plain ol'timey X window, though is far superior for my heavy use. It is almost as effecient (operator wise) as 'drag and drop', just one more mouse click. Now the MS rip variation of cut and paste takes much more interaction per cut and paste operation multiplying out to much more and slower work for the user.

    Darn, you have forced me to examine my memories a bit closer, of course you must be correct.

    In 1974 I became active in RTTY (radio teletype) via amateur radio. The old surplus 60 baud teletype machine caused me to take special note of an extended article in Radio Electronics?? to build a solid state terminal. The Altair came out before I got the parts and all together and I decided to go for that.

    I purchased the Altair 680b and Lier Siegler ADM3 terminal, both in kit form for about $3k. 2MHZ 6800, 16k of static ram using 4kx1 chips. A 300 baud kansas city standard cassette interface card, along with an assembler and 8k basic completed the package. There was no operating system.

    My first hack was to the basic to replace the cassette I/O routines with serial port I/O to utilize a 2400baud external cassette data recorder. I learned manual dissassembly of machine code for that.

    The 6800 UG in town had two guys with Southwest tech 6800's, one with a Smoke Signal Broadcasting system, one with a Motorola development board system, one with a totally homebrew wire-wrapped job (and home brew os via home brew asm in the works) and me.

    My first paid programme was for an eprom to turn another fellows 680b into a serial print buffer for his new CP/M system printer, made $100.

  8. perspective plus on What The Dormouse Said · · Score: 1
    I bought a mits altair 680b kit in 74' or 5 when it first came out. The stuff in this article did not yet run on any 8080 or 6800 of the day. It was all machine code, asm, basic or fortran. A TOS (tape os) came along for 8080's and CPM. All these were command line things, far from the 'drug' influences gui mouse culture described in the review.

    Then ibm came out with the pc, still no gui stuff.

    Meanwhile... at Bell Lab's me thinks a bit of dope was inuse.... and now we have unix and linux and yes, windoz all with gui front ends.

    Methinks a bit of a spin is in use with the book of this review.

  17. Re:Taking care of some things in one post. on Breakthrough in solar photovoltaics · · Score: 1

    Great Post! But efficiency does matter, it sets the limits to how much power you can derive from the area you have. Low efficiency drives you to tie up more realestate to reach a given power capability. A larger installation also drives up the cost of installation, wiring and maintenance.

    The migration/upgrade projects we plan and execute, all come back to us admins to figure out wtf to do and how long it will take. The pm keeps a timeline and gives pitches to upper mgmt to keep them in there cages (and the money flowing, etc). The benifit of pm to us is simply to keep us honest and make us formalize the plans. Thing is we must fully understand how to get where we are going from where we are. No project mgmt approach can replace that.

    " these are mostly sources they do not know, and thus (hopefully) will not trust"

    While this reflects the prevailing so called 'wisdom', I find (for example), slashdot to be a treasure chest compendium for things computational. While one does still need to sift the comments, it isn't hard to gleen much gold, especially when branching into something new or trying to polish a fine point on something old.

  20. Not if it is all a hardwired hardware design on Intel Develops Hardware To Enhance TCP/IP Stacks · · Score: 1
    While I've no clue how intel is gonna implement this, if they do it all in real hardware (no uproc and no microcode), it'd be right hard to hack.

    In addition, for economy and speed, the stack would not necessarily be implemented as serially as it is in a full software implementation. Also most operations would occur in one clock cycle.

    Of course upgrades to tcpip would be - replace the card.
