  1. Re:Informative graphic on No Spitfires In Burma After All · · Score: 1

    No, not really.

    For instance, under performance, the Spitfire mark 1 couldn't climb any faster or turn any faster than contemporary Hurricanes. It was much faster in a straight line, but the tooltip doesn't mention speed.

    The elliptical wing does not reduce drag as stated in the tool tip. What reduces drag is the fact that it was very thin. The elliptical wing was a compromise to allow it to be very thin and still have room for the undercarriage, guns, ammunition and cooling equipment.

    The twisting of the wing (called washout) was not done to make the plane harder to stall but to alert the pilot when it was about to stall and to maintain control in those conditions. Because of the twisting, the wing root stalled before the tip causing the plane to vibrate and thus alerting the pilot. Also, because the tips were not stalling at this point, the ailerons (near the tip) were still effective, so the plane was still controllable.

    If you purchased your computer with a copy of Windows already on it, almost certainly, the licence is tied to that machine (legally, if not technically).

    If you purchase a copy of Windows separately in the shops, you can transfer it, but also, it is much more expensive than the nominal cost of the OEM licence.

    Technically, the units are metres and kilogrammes. It's not obvious from the Wikipedia article, but I don't think that adding a prefix (or removing one to get "grammes") counts as making a new unit.

    That said, the 1/4 mile is often considered the ultimate test of a car, and I'll mention about the first fucking thing they do on Top Gear UK with very nearly every-single-car they bring on there. If they do a comparison test its always either 1/4 mile, standing mile, or 0-100 and back to 0, which are all essentially the same thing.

    Firstly, they're not the same thing. The 0-100-0 challenge is a much more complete test of the straight line ability of the car seeing as it's likely to involve more than just first and second gears and also the brakes.

    Secondly, the straight line test is often not treated totally seriously by the Top Gear crew. The important test is the timed lap around the track. The best M3 has a time of 1 minute 25.3 and the best Mustang has a time of 1 minute 28.

  14. Re:Did he already heard about integrated debugger on The IDE As a Bad Programming Language Enabler · · Score: 1

    In my first professional programming job, the chief debugging tool was a stack dump. The run time would literally print the whole of the process stack onto the line printer, using, on average a third of a box of paper. Since this was Burroughs B5000 architecture, that was the whole program state. Of course you'd have to wait an hour for the print to finish and if you ran out of paper or had a jam that was it.

    I'll take the debugger every day over exceptions with more information.

    As others have already said, the tools are free, the $99 is needed to run youre apps on a real device rather than the simulator and to submit apps to the app store.

    I have to say that all this whining about paying $99 makes me smile a bit. At my company's charge out rate for me, that represents something less than an hour's time. The first C compiler I bought for a PC cost me something like £400 in 1995, which, with inflation is about 10 years of subscription to the Apple Developer programme.

    The theory was that a pilot with a parachute would be less likely to try to save his plane when it got hit by enemy fire. That probably says something about the economics of pilot training and the cost of aircraft at the time.

    There were also practical issues. For the most part, aircraft were very small and low powered. It would have been difficult to fit a parachute in and the weight penalty would have been significant, but then again, German aircraft did have parachutes by the end of the war. Apparently Göring was saved by one.

    Amazon. Apple has loads of cash but few assets. No factories, no licensable technology patents, nothing beyond its own products. If they ever go out of fashion Apple is screwed. Amazon on the other hand has a solid and diverse business with physical and intellectual properties to back it up.

    Apple could solve that problem by buying Amazon.

    So who does marketshare matter to?

    Everyone, in the long run.

    For a corporation, the only thing that counts is return on investment. Market share feeds into that for two reasons.

    Obviously, if you sell each unit at a profit, you make more money by selling more units and your fixed costs go down as a proportion of your total costs.

    The other reason - and this is especially true in the world of software - is that people tend to like to go for the market leader.

    This is not, by the way, as simple as Apple against Android because not all Android phones are made by one manufacturer. As a mobile phone manufacturer, Apple is doing very well.

    IOS has a smaller share of the phone operating system "market" (it's not really a market because people don't buy the operating system), but it is easier to make money from IOS both for Apple and for its developers and that's what counts if you are trying to please your shareholders or feed your family.
