  1. Re:don't focus on the language on VHDL or Verilog For Learning FPGAs? · · Score: 1

    Absolutely seconded. If you understand:

    Interfacing hardware (so the labs can control real world stuff, even if only a LED),
    Logic including all kinds of flipflops,
    race conditions (folks whom started programing on CPUs always have trouble adjusting to this),
    fork/join (and whatever the VHDL equivalent is),
    initial vs always (initial as a type of always that only runs once or whatever),
    parallel "programming" in general,
    computer or other system interfacing,

    then, and only then, you're all set to do both Verilog or VHDL. Even if you can only do one or the other in lab, try to at least gloss over both at lecture time.

    Designing a class by starting with the specific lab tool is kind of like designing a literature class beginning with word processor font selection.

    If you don't know the theory, you're lost lost lost no matter if you choose Verilog or VHDL.

    When purchasing a $200 graphics card in a corporate environment, the technical staff will read 200 page technical documents, search google for hours, write reports, run simulations, justify the upfront cost vs long term labor savings, basically spend at least a grand or two of labor costs to pick the best $200 card.

    However, when purchasing a $30K "buzzword of the month" the decision will be made at a high level by a manager whom is proud of being non-technical based on:
    1) What they saw on CSI and/or 24 last night, or maybe Obama's latest speech.

    all three have worked. It is interesting that the 3rd works the least well from what I've seen.
    If people are acting in common because they want to believe it is of value to do so , communism works well. If people are sharing and acting in common because they are forced to by a contract or a government , it doesn't seem to work as well.

    A good fourth example is the US military, of which I was a part of in the early 90s. It's all teamwork, everyone shares, no one owns the hummvee (although is gets weird where one individual signed responsibility for it, yet does not "own it"). This is by no means my unique idea, I heard it all the time when I was in the military, the irony that our military forces exist to save us from the commies but ironically here we are with our military as the only really successful communist society....

    A pretty good summary of basic training was converting attitudes and outlooks via mild brainwashing techniques (sleep deprivation, stress, excessive enforced exercise, etc) from your second example "forced by contract" to your first example "believe it is of value to do so".

    I would interpret that as the only stable communistic societies would be either medieval theocratic (from your other examples) or modern militaristic, and I have little respect for either in general for all to live under (although I personally enjoyed my "time in green")

You end up leisurely taking ten pictures, all poorly framed, bad perspective, poorly timed, wrong aperture/FoV/shutter speed tradeoff, shakey cam holding technique, and poorly lit, and end up throwing out all ten, thus having no usable picture at all... vs the film guy whom feels his wallet lighten each time he clicks, so he tries very hard and gets, perhaps, three Great pics out of every five expensive snaps.

    ..... If you thought going all-digital was going to save you money and you did all your movie in HD video, the day you want to show it in a real theater the first filmout is going to run you more than $1 a *frame*. 24 frames per second.

    That's all very impressive that it takes a village to raise a child and stuff, makes me wonder how my wife makes a home movie of my kid eating birthday cake without a home mortgage loan of expenses, and its all very impossible for a mere mortal individual to make a movie, but how come, relative to the electric car movie, "The BBS Documentary" by Jason Scott is better, longer, more interesting, better packaged, had more "actors" and better graphics, better sound, better DVD mastering (w/ easter eggs and stuff) probably has a higher ROI (although admittedly probably lower total dollar amount of profit) and was done by one dude in his basement? Don't get me wrong here, for an agit-prop documentary, "who killed the electric car" is pretty good and I mostly enjoyed it. Its just the BBS documentary is better, yet was immensely cheaper than your description. Could Jason Scott have blown, say $20 million on his much more complicated documentary? Maybe, but he didn't, as far as I know.

    Let's put it this way, some guy comes to you and says he wants to make a documentary about the electric car. You don't know the guy. Says he needs a million bucks. I'm sure you wouldn't give him even one hundred bucks.

    Didn't slow down Jason Scott, he just did his movie anyway. Doing his next video on text adventures all in HD, according to his blog. Very impressive. Interestingly, he asked for people to front him a small amount of money to buy HD gear, and plenty of people did in a very short amount of time. I would have, but didn't have time before he collected all the cash he needed.

    Can either use little magnets stuffed in the pointer fingertip of the gloves, or big ole hard drive magnets kind of held in the palm. Or both, I suppose, but be careful they don't stick together.

    I've tried this and it works quite well until your hands sweat too much from the gloves being too warm inside the house. Old fashioned linear power supplies are much more entertaining than modern switchers. It's pretty strange knowing by touch if a material is ferromagnetic, because it's "sticky". I was not able to move my hands fast enough / use strong enough magnets to experience magnetic braking when waved over conductive surfaces, although I suppose it should be possible with stronger magnets. Tiny bits of magnetic junk built up on the gloves as I pawed everything... Best not touch CDs/DVDs when covered with magnetically attached iron shrapnel.
