  1. Re:Most of their manuals do suck. on 500-in-1 Electronics Kits? · · Score: 1

    Actually, there is at least one kit that contains guidebooks by Mims. My only complaint is that there isn't a variable capacitor included, so you'll need to scavenge or buy one if you want to make an AM radio or something.

    There are also certain subtle UI features that don't even necessarily affect you at a conscious level, like the way window shadows are done, or the way Exposé makes the background fade.

    Ideally a story and progression would be expressed in some way other than just replacing your +2 sword with a +10 sword. If you look at the narrative structure of something like Lord of the Rings, the events at the beginning of the story seem minor by the climax, but they didn't seem minor at the time. I believe GP's complaint is that things at the beginning of the game seem trivial and stupid as you are doing them.

    Also, to successfully hand-optimize you need to remember a lot of details about instruction pipelines, caches, and so on, which is fairly detrimental to remembering what your program is supposed to do.

  5. Re:Ugh not again... on 2006 ACM Programming Contest Complete · · Score: 2, Interesting
    Speed is probably the most visible aspect of ACM programming contests, but really correctness is the most important criterion. The scoring system gives you 0 points for something that passes 95% of the tests, and the feedback is not much more informative than yes/no.

    My own experience is three years of regional contests and two at Worlds. The usual allowed languages are C++ and Java.

    In the first year I wrote essentially in the C subset, although I did sometimes make declarations in the middle of a block. If I needed to keep a couple hundred ints around, I would have int x[1000]; usually at global scope, and I often had a 500 line main function with a few occasional gotos.

    During the second year I started modularizing into shorter functions and also making some use of STL containers like vector and map. My code was not particularly object-oriented though.

    In the third year I switched to Java even though hello world and input/output formatting are substantially more verbose than in C. (We usually had 1.3 or 1.4, so no printf.) The time efficiency of an ArrayIndexOutOfBoundsException compared to what C++ would usually give you was worth it.

    Over the years, as I tried to increase my own productivity, my code became more organized and readable. It wasn't a process consciously directed towards good software engineering.

    (My code was rarely very OO, however. For a small, one-person project that doesn't talk to other systems I doubt it's much of a performance gain.)

    US TV remote controls can turn the TV "on". Of course to do this, the appropriate circuitry to detect the power signal has to be kept running continuously, which isn't free.

    Actually, the minimum enlistment age is 17, with parental consent. This is one reason the US has not yet signed the UN Convention on the Rights of the Child (the execution of minors had been another).

    Either is potentially correct. "A full four" is used to emphasize the number, e.g. "But this new, fuller footage shows Bush sitting for a full five minutes after he'd been told that 'America is under attack.'" On the other hand, "four full" would imply that each of the discs is full.

    One way to do it is to calculate the total work done on a point mass m as it travels from close to the sun (starting at 1AU or wherever) to infinitely far away, using Newton's Law of Gravitation and simple calculus. Then to escape the object must start with at least the equivalent amount of KE=.5mv^2, from which you can find v.

    The Supreme Court has held that non-defamatory anonymous speech is constitutionally protected (see McIntyre v. Ohio Elections Commission). In the article, the court ruled that the statements made by the bloggers were clearly opinions, which can't ever be defamatory.

    Bad statistics. All the FBI statement implies is that 99% of privately-owned weapons haven't been used in the commission of a crime. The privately-owned weapons that were used in crimes could be any percentage.
  24. Re:It's already a solved problem. on Fold 'n' Drop Window Interaction · · Score: 1

    The actual graphical speed was not slow enough to be noticeable. I was talking about the physical delay of moving the mouse toward and over the corner of the window at the right speed, stopping, pulling back a bit, and continuing this process for every window in the way. It's much faster to start dragging, hit F9, throw the cursor over the appropriate window, and hit F9 again.

    It is probably more natural and intuitive to use folding windows, but from playing with the demo it also seems to take several hundred times as long as using Expose.
