Its completely broken with perfectly legitimate local DNS URLs.

Can you give an example of a 'perfectly legitimate URL' that doesn't work? (Hint: all URLs begin with a scheme such as http: or file:)

In my first year at college, I pushed a friend (by accident) through a plate glass window. The college authorities fined me £50 and asked me to be more careful. [friend] was taken to hospital, lost a small slice of an ear IIRC but was otherwise ok.

We were sitting in the college bar, pretty drunk, and there were these thick radiators that ran along the windows which people sat on. [friend] had slid down between the radiator and the plate glass (10' x 10') window, and I thought it'd be a fine idea to get him stuck down there, so pushed him down as hard as I could...

Plate glass windows make a lot of noise when they break...

I do remember grabbing hold of him and pulling him back as soon as it happened, which may be why he still talks to me :) It may also be why he didn't get a sheet of glass through his neck, Exorcist-style.

The dean in charge of my hall-of-residence was particularly scathing when he found out I was studying physics at the time, various comments about the fragility of glass were made, but his (and the college's) attitude was "shit happens around students". The fine was their way of saying "don't be a dick, again".

Of course, this was the UK, not the US. I also wrote a networked virus without ending up in jail...

People repeat this meme that desktop OSes don't support high resolution displays, but it's not really true. At work I have Windows 7 and several 3840x2400 displays; just setting 200% font size works fine in all the applications I use.

Well, yeah, surely 4000x4000 is 4k (like IMAX), and 3840x2160 is only about 2k measured conservatively.

"Riddle me this: what is it that is always coming, but never arrives?"

So you have your nicely written function of type int -> int, but now you want to add some trace statements while it executes, but you can't because it is purely functional. Then someone helpfully suggests monads. Now all you have to do is rewrite it to be of type int -> IO int, and rewrite all of the calling functions to be of monadic type too, and so on all the way up to the top level of the program...

The fundamental problem is that you need some way to separate the program itself (which is purely functional) from whatever scaffolding and diagnostic code you put in to help test and debug it. In imperative languages you can happily mix the two together but in pure functional programming you can't, and the language environment has to provide explicit support for trace messages and the like.

IMHO Windows 7 requires Classic Shell and some messing around in Control Panel to make it usable. Essentially, with each new Windows release there is another half hour of setup you must do to get rid of the latest bright ideas from Microsoft and get back to the basic but usable interface circa 1999.

That US remake of House of Cards isn't too bad.

I remember on the Archimedes using PC emulators, both Acorn's one (which was oriented more towards business applications) and Dave Lawrence's FasterPC (optimized for older DOS games using 320x200 256 colours). Both only emulated an 8086 (or 80186 in FasterPC's case), so they were good for Civilization or SimCity but not newer things. I mention them because, to squeeze decent performance out of an ARM running at speeds as slow as 8MHz, they were hand-written in optimized assembler. This was the older 'ARM26' instruction set where the program counter and flags were contained in a single 32-bit register, so the code would need modification to run on recent ARM processors; and in any case the I/O part of the code will be totally different. But that doesn't stop me wondering about the core CPU emulation and how fast it might go on modern hardware.

So Windows 8 doesn't have the Aero Snap, Aero Peek and other animated window management thingies? I can understand that Microsoft marketing stopped calling it "Aero", and that Aero Glass (the odd half-transparent effect on window borders) has been dropped, but I thought the thing itself (whatever it's now called) had been kept.

Sorry what? 'Light' and 'heavy' can be used as relative terms, just like big and small, hot and cold, or pretty much any adjective in English. If you say 'the lightest substance', it's quite clear that you are talking in relative terms. Also I think you are confusing 'substance' and 'object' - a single neutrino is not a substance, it is an object. Water is a substance; a drop of water is an object. I mentioned gravity to deflect any possible nitpick about 'heavy' being different depending on what gravity you measure it in - since we normally understand heaviness as the force of an object being pulled towards the ground, in other words as a measure of weight rather than mass.

It is normal to describe a material as light or heavy. These are shorthand for 'weighs less for a given volume' and 'weighs more for a given volume'. If you assume gravity is fixed - a reasonable assumption, since we all live on the same planet - this also implies 'less dense' and 'more dense'. What's the difficulty?

In fact there isn't a big issue with Windows XP compatibility and hi-dpi displays. I use a couple of 204dpi monitors at work and until recently ran Windows XP on the PC. Just set font size to 200% and pretty much everything works fine - there are the occasional things like installers which render with fixed pixel sizes and so have tiny text, but the applications you use every day don't suffer from that. Windows 7 is a bit better still.

I'm reasonably happy with Classic Shell, plus disabling Aero and other animated junk.

Thx - I didn't know about any of those except Win-L to lock the screen. For my style of working (every window maximized on one monitor or another, no Aero or gadgets, file manipulation mostly from the command prompt) they are not that useful. But I can see why others might like them.
