  1. Re:Where's my engineering document? on Why Programming Still Stinks · · Score: 1
    In software, you are typically trying to make one person be both the domain expert (the mechanical engineer), and the tool and die maker (the implementation expert).

    The component count in a useful embedded software product probably falls between that of an automobile engine, and that of an entire automobile. Some of the parts in that automobile are indeed simple standardized bolts and washers, but then there are all the others which, when they break and must be replaced, cost $382.27 at the dealer's parts counter.

    Demonstrate that the mechanical engineering model miraculously brings a software product from concept to production, with fewer people and at lower cost than Ford or Boeing or Bechtel require to produce a tangible product.

    Look also at the magnitude and time scale of the investment comparatively between the mechanical product and the software product, both in design, and in design verification.

    As a fellow long-time coder (30 years), I must in large part agree, though I find it very difficult to part company with my "pathetic" need to print. I just wish I were printing something more informative than code as we know it.

    Our tools are absurdly dull. In December, I visited the Getty Museum, and saw an exhibition of sculptures by Jean-Antoine Houdon. The sculptor uses a hammer and a chisel or two, and a nearly incomprehensible amount of vision and skill, to produce magnificent works. Slowly.

    And here, I as a programmer, try to build works which, if not magnificent, are at least functional, by gluing individual grains of sand together under a magnifying glass, with a pair of sadly deformed Ubangistani discount tweezers, and some dubious glue.

    If I use too much of my past experience in the work, my previous employer will sue me to ruin. I must either be indentured for too long to one master, or must behave as if my mind has been substantially erased of the most directly useful elements of my previous efforts.

    Simonyi also makes a valuable observation by delineating the problem of domain expertise vs implementation expertise.

    Every time it becomes my job to produce a piece of code which does something, I spend an awful lot of time trying to be conversant enough with some complex problem domain, to be able to do something useful within it.

    This document makes me ANGRY. The weasly little DC lawyers who wrote it should be strung up by their whatevers and left to hang in a public place with a generous supply of large rocks nearby. Its tone is not that of something issuing from a checked and balanced organ of a constitutional and freedom loving republic.

    Gems such as "The rules should make it clear that carriers are not permitted to argue in any petition for further extension of the Packet-Mode Deadline that the service for which a further extension is being sought is not covered by CALEA."

    I'm sorry, but this is the language of paranoid totalitarianism, not of a democratic and constitutional republic. Much as I would like to blame this solely on Ashcroft, CALEA goes back an administration or two.

  4. Re:MHz vs. MSPS on Cheap PC Oscilloscopes - Any Recommendations? · · Score: 1
    It is all too frequent to confuse the bandwidth of a scope (or the frequency of a sampling process) with the fundamental operating frequency of the system under test.

    If I have a digital system running with a 50MHz (nominally square wave) clock, and I put a 50MHz bandwidth scope onto the clock, I will see a 50MHz sine wave. That gives me some information, but not much more than the fact that the signal is present, and has some approximate amplitude.

    To actually see the squareness (or lack of it) of the 50MHz square wave, I need to add an infinite series of odd harmonics (150MHz, 250MHz, 350MHz, ...) of decreasing amplitude: sin(n*x)/n, n=1, 3, 5, ...

    To get a meaningful idea of whether I have impedance mismatches between source, transmission line, and load (causing reflections and thus clock glitches, or clock to signal skew or jitter), I could need a scope with at least 350MHz bandwidth to see what is really happening in those crucial few nanoseconds of the signal transitions. In digital terms, this would mean a sampling rate of at least 700MHz.

    Crystals in the usual MHz frequency ranges are NOT especially expensive to obtain at custom frequencies. Circa 1972 I had one made in the 4MHz range and it cost me around $13.

    The place which made them was not far away from me, and you could see the simple benchtop polishing machinery from the front counter.

    The situation with 32768 Hz tuning fork quartz resonators for watches is a bit different. I suspect, though, that even these are susceptible to hacking.

    Just open up that tiny tubular can, put the crystal into a vacuum deposition system, and evaporate a bit more metal onto it (increasing the mass of the fork arms) until it oscillates at 31903.94 Hz instead of 32768. Whether you are going to be able to pull the frequency down this way by as much as 2.64% is an open question. Then find a way to repackage it.

    The way you did this back in the days of WW2 surplus crystals in screw-closed FT-243 holders, was to open up the holder and use a soft pencil to make a mark on the surface of the crystal, increasing the mass slightly and lowering its frequency. To increase the frequency, you would grind the crystal thickness down a little against plate glass with a very fine abrasive (e.g. toothpaste).

  8. Re:Any members of ACM or IEEE Computer Soc? on Great Computer Science Papers? · · Score: 1
    I have been a member of IEEE CS for a number of years, with a couple of gaps during times when the considerable expense seemed imprudent. I add and drop publications as my interests change. The expense can be stiff, especially if one maintains diverse interests. (IEEE once called me up and asked if I was breaking the rules by trying to use personal rate subscriptions to stock a library.)

    I was previously a member of ACM. At one time CACM was something to look forward to every month, and it was visually elegant. Then they changed to computer typesetting and for some reason decided to use a hideous ragged-right layout, further mulching the pages with a rotten salad of silly display fonts.

    Worse, the good fundamental articles disappeared and were replaced by institutional bleatings, e.g. "eating our seed corn", and promotion of the fads of the moment in so-called "software engineering".

    I ascribe the demise of CACM to the editorial tenure of P.J. Denning. Perhaps I am not being fair in this, but that is the opinion that I formed at the time. It must be recognized that the field is vastly broader than it was during CACM's glory days of the 60s and 70s.

    You cannot make any such conclusions from the face of the issued patent. You would have to examine the "wrapper" (file history of the application) to learn the real story.

    Lemelson is infamous for these sorts of "submarine" patents, kept on the slowest of snail's paces in the examination process by amendment after amendment.

    After enough iterations over the years, the application is finally allowed to gel on some concept just a little ahead of the documented state of the art, and the hook is set.

    It would be good if the actual MOU were published somewhere.

    It is almost certain that 5C protection is specified for the 1394 interface. And it probably also specifies Macrovision for any analog video outputs.

    Sadly, there are no fewer than 4 broadcast digital systems in use in the U.S. today: digital cable (64QAM or 256QAM modulation), ATSC (for airwave broadcast: 8VSB modulation), DVB-S for Echostar, and DirecTV's system.

    All but DirecTV are based upon MPEG-2 Transport packaging/framing (but most MPEG decoder chips can handle both MPEG-2 Transport and DirecTV framing). Each has its own modulation, Forward Error Correction, and interleaving scheme, due to the differing respective characteristics of the cable, airwave, and satellite channels.

    Add to this several different conditional access systems. Perhaps this agreement specifies CableLabs' POD pluggable conditional access module framework.
