Chess. The graphics aren't great but it's still just about the ultimate game of champions. Beaten only by Gravity Power on the Amiga.

And how many thousands of dollars worth of skilled security researchers' time?

That's a problem with the law, not the dog.

Having read the link, that does not really prove that dogs are useless, just that they can give false positives if the handlers lead them into it. But no-one gets prosecuted because the dog thinks they might have a bomb unless it turns out they really do have a bomb. False positives are not a big problem if the alternative is either much more thorough/time-consuming/intrusive investigation or random selection.

And to make sure the light beams don't get crossed over, you could use some of thee new-fangled glass-fibre cables... oh hang on...

All that junk is on eBay, Maplins have been selling half of it for years.

Exactly, go back and read the stuff about the nuclear tests, they had everything they could find lined up around every blast - from live animals strapped to the decks of target ships to food, drink, etc., plus of course all the scientists and soldiers stationed about the place to observe & report. As someone above said, the cost of setting off the nuke is the big thing, so you may as well stack as much stuff around the place to gather data on.

Cameras can also *see* cars, fake plates or not. If the ANPR hadn't flagged it right off, there's a fair chance the CCTV guys would have spotted it - and they could just as easily then stick the fake reg into the computer.

There's also a difference between car theives who sneak off with your stuff and car theives who are willing to risk an assault / ABH/GBH charge and the associated police response / prison sentence.

But you're right, we should go back to the police having a truncheon and a whistle and maybe a horse...

I think it's funny that google, amazon, and your bank/credit card probably know waaaay more about you than the authorities do, yet things like this get shit on in the name of freedom. If I get mugged, or burgled, or whatever, I want it to be on as many cameras as possible. CCTV is a massively EFFICIENT and EFFECTIVE way to catch criminals and make the Police and justice system's job easier and safer. With power comes responsibility, and we should be watching the watchers very closely, but not cutting off our noses to spite our face.

A friend of mine heard his car being driven off his driveway at night, called the police who typed his reg into the computer. Within a few minutes it had been ANPR'd leaving town, one camera later they knew fairly sure which way he was headed (motorway out of county), maybe half an hour later a police car rolls up behind him at a motorway services and cuffs both occupants, car returned to owner.

The issue is not the technology, the issue is how it's used and by whom. This is an excellent system for reducing vehicle crime - theft, unisured drivers, unsafe vehicles on the road, etc. that cost us all a shitload of money in taxes, insurance premiums, death. They can do this as much as they like, I'm cool with that, but I want to know that that's ALL they're doing with it, and that they're not selling my data etc. etc.

People need to stop getting all antsy about the technology and concentrate their attention / concerns / questions on HOW it's used.

Is your bike... PAINTED?

Pretty much anything electronic generates some noise, as pretty much everything has some sort of oscillator in it, because these days everything has some sort of microprocessor in it. Even if your device is off, its battery might have its own processor ticking away. Any device which remembers the correct time through power-down must have *some* oscillator running ALL THE TIME. Your phone probably has 3-4 radios in it (1/2/3/4G, WiFi, Bluetooth, NFC, FM). There's so much complexity hidden in modern stuff (not just obvious electronic devices like phones/laptops) that people forget it's even there. And sometimes made very poorly.

I realise there's a low quota of hardware nerds on here, but most electronics gets washed on the production line to remove flux and contaminants.

The biggie with *any* electronics is to not use anything that causes damage or corrosion, and to have the device powered off until it's absolutely dry (if using water) to prevent shorts or electrolytic corrosion.

The best thing is isopropyl alcohol, aside from being a bit of a hazard to some paint/stickers etc. it's about the top thing for cleaning electronics.

Are you sure it's not craploads of shit? Whatever it is, there's a fuckton of it.

I can recommend www.pun.net, partly because a friend of mine is lead dev.
