  1. Re:Insulting but necessary on Ask Slashdot: Are Timed Coding Tests Valuable? · · Score: 1

    These hash twins would probably have failed at an interview where, rather than just setting a programming test, they were asked "how would you solve this problem?", and as they flapped their arms and talked about inline assembler (I'd have booted them out of the door by that stage), they could be probed "so, what kind of data structure would you use?". You wouldn't need to see them write the syntax for the associative array, but you could tell whether they were familiar with the concept. Of course, such an interactive setup gives them the chance to ask back "what are the access patterns like? ratio of reads to writes? are some elements accessed very frequently compared to others? would those access patterns change over time, or be time independent?" which would show that they didn't just know about the general concept of such data structures, but that there were many many implementation choices.

    That set-up can also help the guy who chokes under the spotlight, but does actually know his stuff - you can gently squeeze the knowledge out of him.

    But as a further handy hint, don't waste time uglifying your code with constructs such as '(0 == expr)'. It is more important that code be readable, and "if zero is ..." is not a useful thing to read.

    This is good.

    At one interview, I got asked to review a page of real code from their current development tree. Asked for three to five things, I spotted half a dozen major things, the same number of minor things, and a few cosmetic ones too.

    I was on my first company social later that evening.

    Being a skeptical engineer, I wouldn't parrot a misleading figure like "22364 miles". I wouldn't even use a more appropriate figure like "22000 miles", I'd use the original figure, in its original units - "36000 km". Of course, being an engineer, I'd want to attach a standard error to that measurement too, which seems to be about 10-20%.

    But yes, gravitational systems can behave stochastically. However, there are no objects heavy enough to tug on Apophis enough to perterb its orbit enough before 2029. Our slingshot on it could have an wide range of possible outcomes, of course.

    That's not how probability works. The same could be said about *anything* in the future or is currently unknown. So it's basically meaningless.

    I heard of one respected hi-tech company giving a 3 hour C programming task. I scribbled my solution on the back of a beermat in about 3 minutes. Were I to have been able to do it in a functional language, it would have been a 1-liner.

    I can only imagine that a 45 minute test would be "write a program which says 'hello' to the world".

    > I think you're underestimating the scale of the switch from B&W to color. I still remember when my parents got a color TV (we had a B&W set far longer than most people) and the difference was amazing and quite apparent to everyone.

    I'm guessing from your spelling that you were watching a puke-tastic NTSC signal. Those who didn't let their colour channels drift out of control by alternating the phase on each line had an altogether less psychadelic TV experience. (Modulo TV presenters clothes, of course.)

    So it might have been a very noticeable difference you were seeing, but it the change wasn't all improvement.

  9. Re:But it does require 150MBPs on The Trouble With 4K TV · · Score: 1

    If you're mentioning physical media and renting, then clearly you don't view "TV" viewing as something that needs to be done in real time simultaniously. In that case, why did you not consider simply downloading at 1/nth speed, and watching later? What is it about 4K that excludes it from that usage pattern? If anything, it seems to encourage a "just torrent it afterwards, and watch it later" attitude due to the difficulty (i.e. cost) of streaming it. And for that, this is nothing but an evolution of what people are currently doing, not a revolution. 4 times the bandwidth is just a small constant factor (either in your patience, or your ISP connection).

    They are the middle and the endpoint. Without any proxying, you only have to trust their client on your terminal. With the proxy, you also have to trust their proxy on their server.

    Fortunately, no servers have ever been hacked, and nobody's ever written an insecure proxy, so that worry can be dismissed.

    Theorem: In a time-independent stochastic system, extremal events occur less and less frequently over time.

    Input: We're seeing no fewer extremal data points than before, typically more.

    Conclusion: Therefore we are not in a time-independent stochastic system. I.e. something is changing over time.

    Note - I agree with you and I would *not* count Sandy as being a datapoint for extreme weather. It had lucky/unlucky, depending on your perspective, landfall, that's all. There's no reason not to expect real hurricanes (Sandy was a TS), to make landfall in the same place in the future. Hopefully fewer people have their generators in their basements next time.

    But do you really have evidence that SCOTUS is any different? I know people like to *believe* it's *infallible*. But that's what others say about religion too, using identical terms. It's even got an old document, written in several phases, which (apart from revisions) is considered the absolute truth to support itself.

  16. Here's a similar situation - the capital city of Estonia, Tallinn, has just announced free public transport for all city residents. This altruistic move will make the city money, not cost them anything. How, I hear you ask? Because the Estonian government finance towns in proportion to their registered population, and amazingly the registered population has just jumped by 10% since the announcement of the scheme. (Which of course means I'm paying more for my free public transport than I ever did when it cost me money.)

    I think I'm an odd case as I was born into an F-using environment, dropped it for C at an early age, and then never took my temperature since then. I don't have a medical thermometer in my home, and haven't done for decades. So I don't even know what's a high temperature or a low temperature, as it basically means nothing to me. It's not an input I ever need to process. I can parrot "98.4", as some magical incantation from youth, but it's nothing more than shamanistic babble to my adult self.

    As someone in Alaska, I presume that your nose will tell you the outside winter temperature to within a couple of degrees? Here in the European north I've become pretty accurate. So I do take a sniff and say to my g/f "it's only about -8 today", knowing pretty much for certain that it's not -10, or -6. Accuracy disappears a bit below -20, though, but such days are rare (and I stay indoors!).
