  1. Re:We don't on Zuckerberg To Teach 10 Million Kids 0-Based Counting · · Score: 1

    Now you could 1 base the indexes, where x[1] resolves to address of x, but the implementation of that is:

    x + 1 - 1, and x[y] in general becomes x + y - 1

    Or you can create a second value called

    x_base=x-1

    and instead of computing

    x+1-1

    you compute

    x_base+1

    with no extra subtraction and now you count like humans do.

    That's going to be true for any language, and the question is posed to every language designer: either the programmer counts from zero, or every array access in the language has a subtraction added to it.

    Oops.

    how about

    if (parityA=(parityB xor parityC))

    is that an extra bug? of course not. It's a buggy construct which luckily gets caught often by the type checker, but still shouldn't be there.

    Any language that states as a goal: omission or elimination of potentially-harmful constructs, but keeps the awful C construct:

    if (x = 3)
    { ...

    is not really serious about elimination of harmful constructs.

    If the person was the wrong person for the job then improve your recruiting program.

    Spoken like a true noob that never had to hire anyone. Hiring is imperfect even under the best of circumstances. You don't believe me? the best hiring process known to man, which takes several years of assessments, relies in numerous tests, and candidates are chosen by a dedicated committee of experts whose compensation is directly tied to performance often results in disastrous hires. It is called the sports draft and every year there are plenty of draft busts in all sports. If those people with (comparatively) unlimited resources still make mistakes, what hope does a company have on a one day interview? Bad people will be hired, that is a fact of life.

    It's actually the complete opposite. Applying numbers to a subjective measure forces you to tease out biases and explicitly state the reasons behind your subjective conclusions. Placing numbers to it is the best thing you can do provided you remember where the numbers came from and keep in mind at all times how noisy they can be, so you never follow them blindly.

    Don't try to let math do your thinking for you (like MS used to and Yahoo is apparently going to start doing).

    In a perfect world yes. However sometimes you need strong incentives to have managers do the right thing in a world where time is a finite resource.

    If one of your employees didn't work out, deal with it personally and realize it is a one-off event.

    It is also less demoralizing if the slackers are let go once a year, as part of a transparent process.

    Not really. Most departments have enough turn-around that you will be hiring 5 people a year, every year.

  11. Should be 1% not 10% on Microsoft Kills Stack Ranking · · Score: 2

    Stack ranking works great if you use it to get rid of the bottom 1% every year. Surely in a department with 100 people there is at least one hire who didn't turn out great.

    The problem is when it is applied at a 10% threshold. It is not hard after a few hiring/firing rounds to end up with teams of over 10 people all of which are very good, yet stack ranking still demands that you fire the "bottom" perfectly OK person-decile.

    Usage patterns like those you describe hold for milder climates like the New England and Northern Europe. For sunnier climes the peak occurs in the middle of the day when the temperature goes up and ACs work overtime. As well, one could program the residential ACs to come on around noon and lower tto 50-60F by 4pm.

    By the time people come home it would be back up to around 70F with no further demands at night since temperature drops rapidly past 5pm in Winter. In the summer this is not a problem since sunset is later which allows home ACs to run for an extra hour or two on solar.

    Part of the problem is that a critic can sit down for two hours watch a movie and write a meaningful review. This is not possible when it comes to software.

    Let me use a real life example: I was an early proponent of Java since my first few interactions with it in 1994 were positive. Only when I was is deep in the bowels of the beast did I start to see the problems: flawed parameter passing model, the "everything has to be an object" religion (which ironically is violated by built in data types), the "you must write a preamble bigger than COBOL's to have a well designed piece of code", the horrible graphics library that if first shipped with, etc.

    After that I realized that maybe moving to Java is not such a good idea after all. I think the popularity of C#/Haskell/Scala/C++11/Python are a result of this realization.
