It is old news that thermal imaging cameras can be used to steal PINs. What I guess is news is that you can get a $250 phone add-on that's up to the task; I'm pretty sure that wasn't the case until quite recently.

I question the practicality of this technique for ATMs; you still need a clone of the card to use the PIN. And if you're going to install a card skimmer to clone cards, the traditional technique of using a pinhole camera to record the PIN entry works just fine, and probably way more reliable. So I'm not sure what the use-case is for this technique; maybe door-entry systems that only require a PIN, I guess.

Yes. What's he going to do with them, scan them? I didn't get anything from the links except that he's trying to "save" them, no explanation of what for. If he's just going to store them somewhere else, then I have to wonder what the point is, as the chances of them ever falling in to the hands of someone who is going to find them useful are pretty small. At least if they're scanned and OCRed, there's a decent chance at least some of them will end up being useful.

I read about this a few days ago on The Register, according to one user there, this particular issue is to do with DKIM and mailing lists (the stuff Linus had issues with was all Linux kernel mailing list messages);

bhtooefr "Basically, Google's enforcing DKIM from certain domains, and if a message is "from" someone whose e-mail host provides proper DKIM, but it's missing it, Google (and Yahoo) servers reject it. Mailing lists aren't usually set up to properly handle DKIM (being, effectively, a relay), and therefore get rejected.

The workaround that I saw one mailing list use was to resend the e-mail from the mailing list's address, append "via (mailing list name)" to the name on the from field, and just have both the mailing list and the original author in reply-to."

Seems like people running mailing lists need to take a look at how spam filters work, rather than mail providers changing anything. If I understand correctly, the policy is sensible and blocks a likely spam vector, and legit mailing lists could easily be set up to not fail that particular check.

For regular mail, I'm like you guys, Google's spam filtering does a fantastic job. I never check my spam folder any more, unless I'm expecting an email and it doesn't arrive, but it's been ages since I had a false positive.

We won't know unless is actually comes to market, but let's no talk as if they're unaware of the economic aspects. FTA:

"Every aircraft has to be designed to meet specific mission requirements including range, number of passengers, speed, payload, high performance (fighter jets), fuel efficiency and cost. Unfortunately, there are always trade-offs. If you have high performance, you typically don’t have fuel efficiency. If you have carry a high number of passengers you lose out on speed or range. These trade-offs have to be juggled to design an aircraft that can be engineered, manufactured and sold at a price customers will pay for. The engineers spend a lot of time coming up with solutions and then seeing how that impacts the other flight characteristics. The sales team then explores the trade-offs with customers to gauge market requirements and potential.

That is exactly the process that the Spike S-512 Supersonic Jet has gone through. As we continue our engineering efforts, there will likely be additional changes to the aircraft that optimize flight and performance characteristics. The latest design meets at the intersection of engineering, business requirements and market demand for an incredible supersonic business jet."

They clearly think there is a viable market for a supersonic business jet, but only time will tell if their numbers add up.

It's not proven that any particular pesticide or agro-chemical is to blame. The fact that urban bees are thiving in cities such as Paris and London, despite all the pollution in those environments, is inteesting. One mooted possibile reason is that cities have lots of different species of plants in their gardens and parks, blooming at differing times, so that there is always nectar available from some of them. In the countryside by contrast, with modern, vast, single-crop farms, it may be that there is only one species of plant in the bees environment, and once that crop finishes blooming, in sometimes a pretty small window of time, there is no more nectar. So it could be farming practices and lack of rural biodiversity that are to blame, at least in significant part.

Comment Re:As long as you don't count CO2... (Score 2, Interesting) 395

CO2 emissions are proportional to fuel consumption, so I guess there's no point measuring that figure; the fuel efficiency of vehicles is a known quantity. I guess it would have been interesting to have CO2 figures included for comparison with the other numbers though.

CO2 level was actually used to automatically identify the exhast gasses in the study, so maybe they actually had those figures, without reading the full paper it's hard to say. From the abstract;

"Based on carbon dioxide measurements, over 100 000 vehicle-related plumes were automatically identified and fuel-based emission factors for nitrogen oxides; carbon monoxide; particle number, black carbon; benzene, toluene, ethylbenzene, and xylenes (BTEX); and methanol were determined for each plume."

The loophole is right there in the article;

Among other things the Commission plans “to end unjustified geo-blocking,” which it describes as “a discriminatory practice used for commercial reasons.”

We only have to wait to find out what kind of geo-blocking is classed as "justified", but I'd bet on most of the kinds that really cause problems for people.

It's being augmented reality does not have any bearing on whether it is holographic or not; augmented reality means that the generated display is overlayed on the real world, so that the user sees both real and virtual objects simultaneously. This could be done with a holographic display as well as with a conventional stereoscopic display.

Heven't seen any convincing info that Microsoft is using a light-field display in HoloLens, although they are trying to make out that they are doing something clever, but the chances are it's not actually holographic.

To me, it seems like the value of BTC so far in 2015 has stabilised at approximately the level it would have been at if the 2013/14 bubble had never happened, and it had maintained the slow growth trend that it was on before that. So I voted for "Be worth more, but by less than 25%" option, since if the value stays stable for a while, it's quite likely to start to creep up a bit. Of course I don't attach much certainty to that; another big hack or exchange failure, or some governments banning bitcoins or whatever, such things are perfectly possible, and that makes such predictions a bit of a mugs game.

"Fortunately the UK has judges of the calibre of Lords Gill, Neuberger and Hodge who, on trusts, would require an actual criminal offence or some other lawful reason, and evidence sufficient to meet the requisite standard of proof, before deporting anyone."

It's important to note that the British courts have already upheld Assange's extradition at all levels up to the highest courts in the land, and so all of those judges you list would also chuck him out in a second if he wasn't hiding behind diplomatic protection in the Ecuadorian embassy. Actually it's more correct to say that they already have done that, since no further legal action is required or indeed possible to effect his extradition. But I take your point on my opinions of Assange, that wasn't the most constructive bit of the post.

Firstly, the UK judiciary is not the UK government. I case you haven't grasped the concept of an independant judiciary, this is something we take quite seriously in the UK, and judges fiercly defend their independence from government (often to the chagrin of the government, c.f. the governments struggles to deport certain islamic preachers).

Secondly, what part of "Mr Assange is, as a matter of law, currently a fugitive from justice" do you not understand? That is a legal fact, and judges are bound to act appropriately. It would be entirely inappropriate for judges to sit there and be addressed by someone who has a current valid arrest warrant for a serious crime outstanding against them.

Thirdly, speak for yourself. I don't like Assange, and I'm certainly not the only person in the UK who feels that way. WikiLeaks may have done some good by bringing certain information to light (although even there it could have done better, a bit more care about what was released and how it was released would have given a lot less ammunition to people who don't want to respect people's freedoms and rights, and possibly lead to better outcomes for people like Bradley Manning), but Assange himself is a hypocrite and a coward, and I'd deport him in a second if I had any say in the matter.
