In my school years I used to fly R/C model aircraft, and for my GCSE design/technology project I built a mechanism and circuit board to trigger a photographic flash unit to indicate when the engine ran out of fuel (fairly simple, magnets in a disc on the prop shaft, and capacitors to store the charge for the flash). This was all pre 9/11 so neither any of my teachers nor I considered that it could be easily repurposed with the flash replaced by a detonator to go off after the aircraft had been crashed into something... In case the plod are reading, I'm pretty sure the hardware will have long been junked by the school as I didn't keep it myself.

Nothing is specifically resistant to ASIC, but they can increase the complexity and/or memory requirements for an ASIC, which shoves the cost and power requirements up to the extent that using a GPU or FPGA is the better option.
Litecoin and other scrypt-algorithm based coins benefit substantially from more GPU RAM, although scrypt ASICs have been on the market since about April, while multi-algorithm based coins (Darkcoin and others that run through a sequential process of 5 to 15 different algorithms) would require a separate chip on the ASIC designed for each algorithm to be the most effective. As multi-algorithm coins aren't as memory intensive, they're the current preference for GPU miners, with a power requirement around half that of scrypt algorithms.
Re: rather than living under a rock
The poll question is rather leading, seeing or hearing a section of the video, well the BBC news at 6 on the day showed a still with a few words voiced from the executioner, so everyone that watches that falls into the 25%. New headline perhaps, BBC turns 25% of UK into terrorists?
Re: To fly, to serve?
The colours are a bit whacky, I appreciate that the idea of "all" (or certainly later) dinosaurs having proto-feathers is gaining traction, but looking at modern avian predators, they're generally variants of brown and grey, with maybe a bit of white, the same evolutionary pressures on birds of prey should mostly apply to Pterosaurs.
Re: Wait... what?
Some people call emergency numbers for the daftest things, maybe they think Google runs the numbers now:

http://www.bbc.co.uk/news/uk-wales-28408175 (There's a fly in my ear!) - this one has a fair list

Bit of a followup to my last post on Devon & Cornwall Police (regular police driving without headlights & ignoring motoring offences), today I see this article on the beeb: http://www.bbc.co.uk/news/uk-england-28437914 (£30,000 spent on repairs after they failed to apply the handbrake on multiple occasions... in the last 6 months)
@Neil B "There is a massively decreased police presence on the roads, and an actual traffic stop is the only way to catch someone doing this."
Some areas there aren't any traffic officers even before the cutbacks, Devon & Cornwall Police for instance have just 7 traffic cars across the entire region, the biggest single police force area in England, and the regular patrol cars couldn't care less about motoring offences. I've seen police cars going round without headlights well into dusk, and they ignore drivers who have a brake light or headlight out - this being a rural area the roads are unlit as soon as you get outside the towns.
Re: Date of birth
Not forgetting the completely secret details often asked for in setting up secret questions/answers, which are limited to about 5 of the following things findable in your Facebook profile (or otherwise known by friends & family): Mother's Maiden Name, Place of Birth, First Job, First Pet, First School, Street You Grew Up On, Uncle's Middle Name, etc.
Since this is often the only line of security in a password reset (which you may need to do at some point, so gibberish isn't always an option), it seems to make picking a complicated password pointless, as you have to invent and remember/record answers. Also see Verified by Visa and Mastercard's similar scheme, which only need the details printed on your card and your DoB to reset the password and make a purchase.
Re: Some things useful, most not
The whole thing seems to have gone out of control, and is indeed fading away from relevancy in modern usage anyway (beyond the blackmailing both of trademarks and smaller businesses).
People are used to typing out a .com/.country address (if its not already bookmarked), or they google/engine of your choice it, or follow a shortened url from a twitter/myface post, and if they are looking at a paper advert with a funny tld url, they'll scan the QR code rather than type out a full domain, not forgetting the apps that work in conjunction with TV adverts too - none of which matter what tld you are using.
These are generally election observers, more interested in spotting whether they could have a case for electoral fraud should their candidate not win, and yes you don't have to give them your number, but I'm pretty sure they should not be asking you how you're voting. If you don't give them a number, they'll still keep a headcount, so as to have a good idea on how many votes there should be in a certain ballot box.
There are also pollsters for the various companies that sell data to the media, who do ask people on exit how they voted, again entirely optional whether you talk to them, or lie to them, never seen one myself so not sure how they identify themselves.
Re: Doesn't matter anyway...
The reference numbers are only meant as a backstop in the case of widespread fraud (ballot stuffing and so forth), the photography rules are meant to stop individuals being bribed to vote one way or another, as there should be no proof that they could provide to an outside individual that they did so.
For the European elections, given the large areas that each election region covers, plus the methodology of determining how many seats a party gets, that level of bribery *should* be impractical anyway (cheaper to bribe the MEPs once they've been elected!).
However, many regions have local elections going on at the same time, where 1000 votes is often enough to return a candidate, so these are very vulnerable to any fraud.
More a semantic point than anything, but a bitcoin wallet does not contain any bitcoins, it is simply an identifier that can be cross referenced against the ledger (blockchain), which is what allows you to make a transaction (signed with your private key). At the moment it still requires far more computing power to brute force the wallet keys (either through collision or chancing on the duplicate of someone's private key) than finding a block by mining directly.
Re: still no top left double click to close
In about:config, set browser.tabs.drawInTitlebar to false (you can also use an option in Classic Theme Restorer to do the same thing, called 'Tabs in Titlebar' on the first tab of options). This brings back the standard windows titlebar to FF, along with the normal application icon to let you close by double clicking.
I had a 550Ti that caused BSODs on my Win7 system (while web browsing, didn't matter if it was Firefox or Chrome) with any drivers newer than March 2013, so crap drivers abound on both sides. Saying that I'm happy with my current ATI card & drivers (or AMD as I guess I should call it these days).
Re: Using someone else's hardware and electricity?
If there's enough slow devices submitting shares (proof of work) to a mining pool*, then they will be earning tiny fractions of a Bitcoin, infect enough machines and it goes from being a pittance to a few dollars or even more per day/week/month.
*Mining pools (for those not into the mining scene) basically let a load of people collaborate their mining power and share out the rewards of mining a block amongst themselves, this allows those taking part to have smaller but much more regular payouts, rather than solo-mining for one big payout which may come every month or even further apart (if you're unlucky, you could go quite a while even with significant hashing power).
MtGox isn't the be all and end all of Bitcoin, yes the value has dropped as a result of the shenanigans, but it was also dropping after the speculation bubble resulting from the US Senate hearings in early December. Bitcoin is still (for now) worth more than the peak this time last year from people trying to get their money out of Cyprus. Re:Next, there's probably in excess of 200 cryptocurrencies that have launched now, and around 50-60 are quite active (in terms of trading and mining), using half a dozen different algorithms, mainly to try and restrict the processing power arms race that Bitcoin (SHA-256) and scrypt-based coins are inspiring.
Other exchanges are available(TM), and you can get cash in or out of them in USD, roubles, euros and a few other currencies. Getting GBP out of Bitcoin is still a PITA though, if you've got serious money to move then you can afford the fees (€100+) and make a SEPA transaction to a UK bank (if you can find one that knows what SEPA is), otherwise you're better off finding a UK/EU merchant that takes BitPay or another PayPal-esque service, and buying physical goods with the currency.
Alternatively just hold onto your funds and see where it goes later in the year and into next year. Once a true use for one or another cryptocurrency is found, beyond the current limited market of speculation and mining for profit, then it may take off in a very real manner. Google and Facebook were non-entities 15 years ago, what will we say about cryptocurrencies in another 15 years.
Re: Summer home replaces pet name.
You'd have to trace some key features around your target area (so if a tree, trace either it's foliage or a set of trees that surround it), which is fine until the satellite picture updates and there are changes that muck things up (two trees down in the storms, or the satellite has a different perspective so tall objects appear to shift).
There's already an alternative cryptocurrency (out of the 100+ that are out there) called Bottlecaps, which is accepted on several exchanges :)
The real investment of the moment is Dogecoin, the value is up 80% in a week, and 750% over the past month or so. In terms of market capitalisation, it is currently in 3rd place behind Litecoin, and may catch it in the coming month or two. The average block reward (the amount of new coins given out when a block containing transaction data is successfully 'mined') is due to be halved by around the weekend, so the supply of new coins will fall, possibly driving the price up further - it depends how much of the current rise is driven by speculators expecting the price to double at the weekend, which it likely won't, IMO the bigger change will be in the mining difficulty falling in response as people switch to other coins. *
* None of the above constitutes financial advice in any shape or form whatsoever, etc. etc.
The angle of impact is a much bigger factor than the Martian wind, given the average atmospheric pressure of 0.6kPa (versus Earth at 101kPa), and debris will be travelling at a significant proportion of the impact velocity (20km/s for a ballpark figure on the original meteorite, barely slowed down by the atmosphere). On Earth ejecta would be slowed to subsonic speeds fairly rapidly.
Re: Wifi? No way
The other *teensy* problem is making it so that it fries car electronics behind a few sheets of metal, without frying someone's pacemaker.
A car-taser perhaps, if the Faraday effect works in that situation to protect the flesh-bags while the delivered current fries any grounded (to the chassis/body) electrical systems? You'd have to be sure to hit something metal on the back or side of the car though, not the lights or plastic bumper (or 4x4's spare wheel). Perhaps some variant of the Finnish car harpoon ( http://www.autoblog.com/2009/10/27/video-finnish-him-nordic-authorities-harpoon-chase-ender-amaz/ ) that contains batteries/capacitors - instead of tear gas! - and doesn't remain attached to the car that fires it, that should penetrate through to the chassis (or the bloke tied up in the boot).
There seems to be a debate as to whether a galactic collision can result in a spiral galaxy, or it always leads to an elliptical galaxy. Give it a hundred million years or so for any of the currently observable galaxies in collision to sort themselves out and we'll have a definitive answer.
China has banned banks and other financial institutions from handling bitcoin, but private individuals can still trade amongst themselves, the setback is with no banks willing to be involved, it becomes much harder to change between bitcoin/yuan, which stymies the involvement of speculators and businesses.
Re: Haven't you seen Fringe ?
Avoid the explosive route and go with thermite, it may not burn for long at that size, but it could be long enough to burn through the floor of the cabin and enter a luggage compartment (assuming it misses any wiring or hydraulic lines) - or just start in the overhead lockers, plenty of clothes/duty free gin there.
Re: Guns won't work, so let's look at alternatives...
Maybe 'rescue' an 88mm German anti-tank/anti-aircraft gun from a museum, along with some flak rounds, see if you can take the drone down that way... Of course, the FBI/ATF may have something to say about that.
Alternatively, wait for a heavy rainshower to soak the cardboard packaging, such that it is now too heavy for the drone to fly at a safe altitude, and have at it with the duck hunting guns.
It's been a bit odd in the UK watching the hotmail (sorry, outlook) adverts that big it up as being private vs gmail's web interface which has targeted ads... except I use the pop3 servers on both, so miss the ads. The hotmail one has crap spam filters too, doesn't block the spammers using hotmail or academic domains among others.
Not the voltage...
It's not the voltage that kills you, it's the amps. Going by a site with info on PAT testing, and it quotes 60mA AC and 300mA DC as sufficient to induce ventricular fibrillation, passing through the chest (direct to the heart is as little as 1mA).
As for concrete providing an earth for the current, it does have a resistance of about 120 Ohms, but it will still conduct (concrete also corrodes through a process of electrolysis, which progressively lowers the resistance to below 80 Ohms).
Re: Age limits?
As far as I'm aware, the videos can be viewed by anyone on the Live service, not just those with the game, and since Microsoft are utter bellends regarding child accounts, everyone generally just makes an adult account anyway. It took about 5 years for them to make an option available to upgrade from a child to adult account keeping your tag & gamerscore (after all, kids do grow up eventually), and the upgraded accounts still don't work properly at everything a regular adult account can do.
Shame they didn't bother to remaster the graphics for the recent PS3 release, though perhaps they should use the team converting the games to mobile for their GTAV iFruit app, which despite being pretty simple (apart from a tamagotchi style interaction with the dog, the rest is all menus), requires a dual core 1.4GHz, which rules out even some brand new devices...
Tellies can handle 60Hz input
After all, 60Hz is what the PS3 and 360 have been feeding UK tellies for years over HDMI. It seems to be more the case that the Xbox isn't handling the frame conversion from the 50Hz it's getting from the TV box to the 60Hz it outputs very well. Simple solution is to not use it as a leccy-guzzling passthrough, and get a HDMI hub if you've not got enough HDMI sockets on your telly (the well-made ones will switch signals automatically with devices being turned on and off too).
