  1. Re:That's the weirdest thing I've read this week on 'You Do Not Need Blockchain: Eight Popular Use Cases And Why They Do Not Work' (smartdec.net) · · Score: 1

    FWIW, #5 is the only one I hadn't seen someone suggest as an application for blockchain before I read this.

  2. Re:COBOL on Is D an Underrated Programming Language? · · Score: 1

    The first is how every language starts out. The second and third are the same thing and have been the goal since the beginning.

    In unmanaged languages, it's generally easier to know/control when allocation happens

    They are everything but a niche.

    Their products may have a lot of users, but I can't say I've seen all that many job postings.

  5. Re:Beards and suspenders. on Ask Slashdot: "Real" Computer Scientists vs. Modern Curriculum? · · Score: 1

    Not really, as memory allocation is performance wise very cheap :)

    Unless your VM can't allocate things to two parallel tasks simultaneously, causing allocation to effectively sequentialize your code.

  6. Re:Beards and suspenders. on Ask Slashdot: "Real" Computer Scientists vs. Modern Curriculum? · · Score: 1

    I defy you to write a compiler or kernel without such knowledge.

    I had such knowledge when I first wrote a compiler, but I don't recall actually using it anywhere. What did I miss?

  7. Re:Several languages on Ask Slashdot: Books for a Comp Sci Graduate Student? · · Score: 1

    Getting a denotational semantics right takes a lot more than familiarity with programming in the kind of language you're specifying. You might be better served by reading up on order theory and logic (get a text that's really pedantic about everything).

  8. Re:Dammit, Jim, I'm a programmer, not a designer. on 3D Printing: Have You Taken the Plunge Yet? Planning To? · · Score: 1

    Looking over the household repairs/replacements we've had to do the past couple years, I can't find anything a 3D printer would have made easier. Faucet aerator has its threads worn down? A new aerator is dirt cheap. Leaking at the base of the faucet? Spend a couple minutes with a wrench. Thermostat's temperature sensor is dying? Not going to be printing one of those. Wallpaper peels off? That's a job for a rather specialized 2D printer, or in our case, a can of paint.

    So tech companies don't want to be in high crime locations in the middle of neighborhoods that most of their workers wouldn't want to live or send their kids to school?

    TIL Roxbury is the entirety of downtown Boston.

  11. Re:No on Does Relying On an IDE Make You a Bad Programmer? · · Score: 4, Informative

    I do remember roughly what a language can do

    Then it seems you do remember something about the language's semantics. Maybe it's the details of syntax you're forgetting?

  12. Re:It's rigged on FISA Judges Oppose Intelligence Reform Proposals Aimed At Court · · Score: 1

    I was willing to give it that interpretation too, but then I got to the part where Bates suggested that the court should choose the adversarial advocate.

  13. Re:It's time on How Your Compiler Can Compromise Application Security · · Score: 1

    It doesn't really take much for that to be the case. Remember, there is no way to decide whether a Turing machine with a given input will reach a given state. All you need is for there to be _some_ undefined behavior in the dynamic semantics -- "division by zero is undefined" is sufficient.

  14. Re:News flash on How Your Compiler Can Compromise Application Security · · Score: 2

    I have never seen a compiler that does that, and I seriously doubt if is really common.

    I'm a bit depressed to find a /.er who's never seen GCC :-P
    I once wrote an overflow check wrong -- I tried to write an `if' that would check whether the preceding operation on signed integers had overflowed. Overflow on signed integers is undefined behavior, so once it happens, it is legal for the program to do anything. "Anything" includes updating the variable with the overflowed value and then skipping the condition check, which is what GCC's output code did.

  15. Re:Technology is hard and dangerous on Toyota's Killer Firmware · · Score: 1

    The jury heard the testimony from all the witnesses. They saw and heard all the evidence. THEN they wanted to punish Toyota. Yes? So what's wrong with that?

    The jury's function is not to mete out punishment. It is to determine whether the defendant committed the wrongdoing they are accused of. When a juror expresses desire to punish, it makes me wonder whether the verdict was motivated by epistemologically sound consideration or by that desire.

  16. Re:packet radio? on FCC Considering Proposal For Encrypted Ham Radio · · Score: 1

    Maybe the problem then is that the business radio systems are (it would seem from the above) much more expensive than ham gear?

    I haven't looked into pricing of business band radios, but it is fairly common for hams to get business radios and modify them for use on amateur bands. I suspect the difference would come out in licensing.

    In many places in the US, this would really be "vote with a moving van."

  20. If something happens to your car while it is parked there, the fact that the owner of the garage has disclaimed responsibility does not mean you have not had your property damaged/stolen. If the police went through a garage searching people's vehicles without warrants on the basis that the people who parked the cars there no longer owned them, they'd get laughed out of court.

  21. Well, if we take the US government's claim at face value, it's because missiles launched from Iran at the US would fly by Central Europe (they would -- check an azimuthal map).

  22. Re:Antennas Above Treeline on Ham Radio Licenses Top 700,000, An All-Time High · · Score: 1

    For the 20-meter band, you're looking at an antenna resonant on 20 meters when 32 feet long and operating 32 fee above the ground.

    Or you give up on having the perfect antenna and work with one placed lower than you'd like (this is how I've been operating at home).

    I would hope the Ohio Supreme Court took this case in order to consider a point of law, not a point of fact.

  24. Re:No snow days on Internet Could Mean End of "Snow Days" · · Score: 1

    I'm a few hours' drive north of 45 (at 47 or so). Local k12 schools call it a snow day when there's enough snowfall to make it unsafe to drive (for reference, people here are used to driving on snow-covered roads). The few times I've seen the university declare a snow day, visibility has been short enough that when I looked out my front window, I could not even see as far as the street. At some points visibility has been too short to even see my car in the driveway. There was also that one weekend when we were temporarily stuck in a town 100 miles away, as the antifreeze had frozen. Had this been during the week, I wouldn't be surprised to see schools close for the day.
