God, how long do you have?
Interactive whiteboards have a touch resolution of about 2000-4000 points on each axis
The same chip is used in an Atari ST for sound, the floppy drive and DMA (hard disk/laser printer) port (meaning if you ever experience music playing during a load screen, someone's been very, very clever). Along with a million and one other ST / other old computer facts that may, at one point, have been useful to a developer, but not any more.
The hi-def TV standard is actually still designed around old CRT-based sets; 1080p is actually the active area of a 1152-line scan, or just over twice that of standard-def NTSC (presumably so marketers could say "more than twice as sharp"). 720p is based off timings for 768-line (i.e. XGA) computer monitors. The widths are a complete accident of using the (very) old widescreen cinema aspect (as opposed to computer ones which come from a desired number of text columns, usually relative to standard size print on standard paper as found on teletypes, or analogue SD TV which doesn't actually have a properly defined horizontal rez).
A fact which is useful to me, and probably me alone: The lenses in NEC VT460 projectors can be swapped out for the short-throw ones from the VT465 with but the twiddling of a couple of screws, never mind the massive warnings to leave it the hell alone and that nothing is servicable. The image elements similarly, if you have a cracked or worn one. Though getting them realigned without UV-proof goggles, a jumper cable to defeat the interlocks, a micrometer and teeny tiny pliers is damn near impossible.
A fact that IS useful: if you're on a budget, hit the 24-hour supermarket at 9.55pm. Loiter round the final reductions shelf for the shelf stacker given the job of finding all the soon-to-expire stuff to come round doing the final clearance markdowns, and nab anything you like the look of right as they sticker it. It'll still keep for 2 or 3 days in most cases, and often what's been left behind for them to collect (particularly off the deli and fresh fish/seafood counters) is expensive primo stuff that's now down to ramen noodle prices. I had flash-fried balti marinated scallops for dinner last night, had homemade king prawn/sundried tomato & olive dressing sandwiches for lunch, and will be doing grilled, herb-crusted tuna steaks tonight... costing less than a depressionburger and limpfries thanks to this.
Just be careful of the non-english speaking foreign broodmother who must have a family of 12 to feed going by the way she expands to fill the entire space available for getting at the shelf and hoovers up all the readymade, uber-reduced sandwich packs (even if there's like 20 of them)... you have to get in before she does. Hence arrival at 5 to 10, not like 11...
Oh, and be picky. There will be all sorts of junk, or still not very good value stuff (something that's overpriced can still be less VFM than the regular brand even when slashed), appearing there on a daily basis. It's easy to overstock, and find you don't like any of it.
