It's the nuclear weapon of electronic warfare: It only needs to work once.
Operating systems should be of major strategic concern. If a real war broke out - I mean proper war, not these middle-easten proxy-wars - it would be easy for, say, the US government to order MS or Google to publish a 'wipe drive and zero the firmware' update and send it via the auto-update mechanism to all hosts in a specified country, thus instantly causing billions in economic damage and crippling infrastructure, communications and ability to coordinate militarily. Or just use the trusted updates as a vector for targeted spyware.
As the world of operating systems is dominated by three companies, all of them based in the US, every country that may conceivably face war with the US at any point in the next fifty years should be working on a way to neutralise that threat by developing their own operating system. Yes, it's a slim possibility - but so is nuclear war, and countries still invest heavily in missile defence.
It wasn't a bug. It was sabotage. Apple issued a patch which has the purpose of disabling a phone if repaired by anyone other than Apple. It was a deliberate decision to prevent third-party iPhone repairs.
Apple claims that disabling phones with compromised fingerprint sensors is a security measure - but then why not just disable the fingerprint detection functionality? The fingerprint sensor is part of the screen, the most often-replaced component due to drop damage.
There's a difference between the unavoidable bugs that come with any non-trivial programming project and a deliberate decision to issue a patch that disables a product for business reasons.
Might be an idea for cloudy hosts running huge datacenters. You could cram the racks closer together if you didn't need to fit humans in between them to replace faulty hardware. A 50% increase in servers/m2 might justify the cost of a robot capable of pulling a failed server out and carrying it up to the service bay. Then all you need is a human engineer to come in every week to turn the pile of broken servers into a pile of working servers and put them back in the 'spares' rack for the robot to pick up again.
If the wind stopped, the air would pile up at the turbine. You need to bring air out at the same rate it goes in mass-wise, but at lower speed, which means higher density. So part of the incoming kinetic energy has to go into compressing the air, which imposes a theoretical maximum efficiency. The Betz limit, or about 60%. Practical turbines tend to be around 50% at most, because achieving that last few percent is disproportionately expensive.
"Inverse square law applies to all point sources, whether omni or directional, in a linear transmission medium."
My laser pointer disagrees. There is no such thing as a point source - it's just a mathematical idealisation. You can point a beam of ultrasound just like you can point a laser. That's the basis for their claim. Like all the best bad science, it has just a grain of truth in it.
The story is of a mechanical oscillator clamped to the building, not sound transmitted through air, and unintentionally. It's not a reliable source - it comes from a journalist prone to exaggeration who claims he heard it from Tesla himself.
I imagine that the experiment may have happened, but the scale was exaggerated in the retelling - he probably just hit the resonant frequency of the building and made it shake hard enough to scare the residents. The story from Tesla claimed he was working on an oscillating steam-driven generator, which is certainly plausible - he did design something like that.
The inverse square law only applies to omnidirectional sources. Their website talks about forming directed beams.
It's still a stupid idea though. At the frequencies they are talking about (60+KHz), sound decays very rapidly - bats run up to a bit over 100KHz for some species, but most call lower, exchanging precision of imagery for range. The beam-forming technology needed is doable but crazy-expensive, and the receivers would need to send a homing pulse so the transmitter could know where to point. And the losses would be highly impractical.
But inverse square law is one of the few things that doesn't kill the possibility.
This sensor is also not going to do you a lot of good on carbon monoxide: It binds to the blood in just the same way as oxygen does. An optical sensor would have a very hard time telling them apart.
I already have an internal sensor for blood carbon dioxide level, and can get a pulse rate just by touching the side of my neck.
They probably wanted to include a super-fast storage device to test the limitations of the software when not held back by storage bandwidth or access time.
It's getting harder to manage RAID these days.
That's why next-generation filesystems like ZFS and btrfs were invented.
"Deliberately with-holding medical care so that someone dies is murder."
In many US states, it's legal to withhold medical care from your children if you do so for religious reasons.
The only way to prevent censorship of the internet is to build it using technology that resists censorship efforts.
Even simple SSL is a powerful tool: MITM isn't practical on a country-wide scale, so it prevents governments from selectively blocking individual pages or inspecting content - all they can do is block an entire host, which creates much more upset from the population. It also makes monitoring communication to identify subversives much more difficult.
Been there. I made a database with a web interface - I didn't bother to bot-proof it as only I had the address and never published it. All was well until I upgraded apache. Somewhere in the process my 'Options -Indexes' on the folder above was lost, exposing the database frontend address to the bots. I got hit by two of them, which between them managed to really mess up the data. I eventually had to get the logs and write a script to identify every URL accessed and undo the operation therein.
Then I put some http basic auth on it. Enough to keep the bots out.
1. (optional) Exclude /bait/ using robots.txt if you only want to block the dishonest ones.
2. Create a link on your index to /bait/banme.cgi, but give it the appropriate css to be entirely hidden from view. Now only bots can see it.
3. Create a /bait/banme.cgi that adds an iptables rule to drop anything from the originating IP.
Well, that was easy.
It's actually just serial logic data. It's not RS232. It does have the right timing for RS232, but not the right voltage levels. If you want that you need another chip that does the level conversion.
Converting to metric and allowing for the planet nearby, you're pulling about 1.5G in that. Enough to make any passengers feel rather uncomfortable, so more acceleration than the finished product needs. I expect they are accelerating a bit harder so they can use a shorter test track, and to test the structural limits of designs.
I still don't see how the expense of this project can be commercially justified. Yes, it can get you across the country super-fast. But high-speed rail is 'fast enough' for a fraction of the cost.
"This can go a bit too far. In Japan, Nagoya and, to some extent, Kyoto and Osaka are becoming dormitory towns for Tokyo."
Half of the southeast UK is becoming a dormitory for London - the city provides a huge number of jobs, but very few people can actually afford to live there.
The stuff-not-rendered must still be in memory in case of a sudden change of viewpoint, to it's easy enough to render a single frame of omni-view. It'd take a lot longer than a normal frame, certainly, but it's only one frame - I don't think users will object if their video freezes for a fifth of a second when they take a screenshot.
I can pretty much promise it *won't* capture geometry, just a pre-rendered image, because the ability to easily extract 3D geometry would seriously annoy game developers... or rather, their legal departments.
I am reminded of the NET act over in the US - it was written to target commercial infringement, but defined commercial as including supplying infringing material with an expectation of receiving more infringing material in return.
The 'boomers' grew up with a television in the corner. It was a somewhat fuzzy image on a small screen with one or two internal speakers. They went to the cinema for the full immersive experience - a screen as big as they can see, detail enough to see the pores in the actor's skin, sound that'll make your body resonate.
The 'millenials' grew up with a 1080p 42-inch surround-sound home cinema system. They see the cinema as just like watching a movie at home - except you have to travel, and it costs more, and there are noisy people everywhere, and the seats are less comfortable than sprawling on the sofa. The only reason they would even consider going to the cinema is that the latest film is super-hyped and not yet viewable by any other means.
Video killed the radio star, and big screen blu-ray... I wish I could say it was to the detriment of cinema. But look at the numbers - the box office takings are higher than ever. Despite the dire claims that piracy is destroying the industry, they are still managing to rake in record net income (though this being hollywood, they always lose money on paper).
" a man who can magically turn water into wine"
Everyone who could afford it drank wine. It was weak wine compared with the wine of today, and consumed in vast quantities. The diet coke of the ancient world.
There's a long history of organisations adopting religious dressing for legal purposes, and the CoS is a prime example. One of their two main symbols is a crucifix with a thin diagonal cross behind. They say that the points each represent a tenet of the organisation or something like that, but the real reason is not difficult to see: It makes them look superficially like not only a religion, but a Christian religion. They aren't - they have barely anything to say about Jesus, and what little they do say is rather unflattering - but they do know that looking Christianish is great PR because a lot of people automatically equate Christian with good.
Another example might be Medi-Share. It's a church to which members make a monthly donation, in return for which the organisation makes a non-binding promise to cover member's medical expenses in event of illness or accident. It is most definately not a health insurance provider though, because those have to pay taxes and are subject to all sort of regulations.
Henry VIII was not behind protestantism. He simply saw a way he could exploit it to his own advantage, as it was a way to eliminate the basis for the Pope's power. Get rid of a rival.
Just invest further in refining BTRFS. It still hasn't reached the maturity of ZFS, but it's stable enough for production use now, and storage management is a whole lot easier than ZFS - you can pull a drive from a volume with ease, unlike ZFS. It just needs a few more features, mostly relating to performance.
Yes, but the accused is a filthy pedo. Possibly the most hated of all criminals. They could charge him with sinking the Titanic and still have a decent chance a jury would convict.
Three to establish.

That's just TCP. They've used a very roundabout way to say their software establishes a quick TCP connection.
Cruz is also a hardcore anti-environmentalist. Climate change mitigation efforts, industrial pollution regulations, endangered species protection, the Clean Air Act - his position on all of them is that he'll get the laws repealed if he can, and if he can't then he'll block all funding for enforcing them, and specifically that he wishes to abolish the EPA entirely. He's gone on record on a several occasions stating that he believes there is no such thing as anthropogenic climate change, and that if there is then it'll be ultimately beneficial.
It's a reference. It doesn't make sense unless you've prior exposure to a certain meme.
I didn't say the IV method was safe. I just said it would help with the hangover, while possibly exchanging it for a more dangerous condition.
Not entirely woo. Part of the hangover experience is simple dehydration - putting saline into the blood will fix that, plus it reduces the concentration of toxins by simple dilution. It's one of the few hangover cures that will actually cure the hangover.
The vitamin stuff is woo though. Most vitamin supplements are, oral or IV - there are a some exceptions, but the vast majority of people get what they need in their food and adding more gives no benefit. It could at least be considered forgiveable woo as, unlike most woo, it does have a plausible mechanism of action.
Because the space adjacent to those channels is already claimed. In the US the bands immediately above and below the 2.4GHz unlicensed band have already been taken by cellphone service. The 5GHz band is sandwiched in between bands sold to commercial satellite operators. Spectrum is a valuable commodity, and every frequency that can be put to practical use has been allocated already. The military gets first pick, commercial services able to buy spectrum at auction get second, and whatever is left may be considered for unlicensed services.
I've been wondering for a while if SDR would enable the use of a sort of 'extreme spread spectrum' approach for illicit radio - jumping around within a band spanning 2GHz or so. Illegal as hell, yes - but it would also be near-impossible to even detect, let alone trace, without the key that determines hopping sequence.
Right now though, spinnydrives offer substantially lower cost-GB, which means they can take over the role of tape as backup/archive media. They are a lot faster and more convenient to access than tape.
Don't be sure quick to dismiss the BBC. They have certainly dumbed down in some respects, but their documentary content is still among the best in the world - and no ancient aliens from them.
I always notice them. I have to feed their locations into the pathfinding area of my brain so it can calculate routes that avoid proximity.
He's making the point that the response of many local governments to homeless people is to nudge them to go be homeless elsewhere.
There was an incident in 2013 that drew a lot of attention in North Carolina, when city police started harassing and eventually arresting a church that tried to distribute food to the homeless - because, much like rats, they congregate where the food is. Withdraw the food and they will scatter and become someone else's problem. It only hit the news because the organisation as a church so they could start the 'wah wah persecution' thing and get a lot of sympathy in certain media circles. There may be next to know public sympathy for the homeless, but much of the US does love a good story about Christians being persecuted somehow.
There's another one brewing in Florida right now, basically a repeat of the same situation - a church in Oakland tried to distribute food, the local government decided this is in violation of zoning regulations. It's not really about religion or about zoning, it's just that influential people don't want to live in proximity to the homeless.
Policing is another approach - many US cities have laws against 'sleeping in a public place' or similar to allow the homeless to be arrested. Quickly released again, but the intent is to harass them in to leaving the area and going to a suitably derelict side of town where the sight of them will not lower property values. Some places have rather less subtle methods, like sloping or very narrow benches, benches with armrests between seats to prevent laying upon them, or buildings designed to create no sheltered alcoves. An up-market apartment building in London neglected to do this in the design stage and was caught instead using anti-homeless metal studs embedded in concrete near the doorway to make sure no-one would shelter there.
Next time you see a public bench, take a moment to look at it - there's a good chance you'll see some feature that, innocent at first glance, on further consideration seems to serve no purpose other than making it impossible for a person to lay down comfortably.
Not even for a DDoS attack. The charge is for 'conspiracy.' He wasn't involved in the actual attack at all: He only urged other people to attack and specified a target. He isn't a hacker, he's a cheerleader. A coordinator at best.
Does it come with a voucher for an extra-strength rack? I have visions of solid steel rails warping like toffee on a hot day under the immense force of that thing.

I'm actually surprised the questions are worded in a way that makes disagreement possible. When they 'consulted' about the filtering, the questions were set in such a way that every possible option agreed with the government's desired conclusion.
Do they pick product names with the aid of a dart board covered in sciency-words?
Is it really a good idea to name your product after something which is best-known for being near-impossible to observe?
You don't need to simulate it in real time, and you can replace a lot of components with simplified representations. You'll still need a silly amount of RAM.
Car engine breaks, so the owner takes it to the nearest convenient garage. They charge him a fortune (of course) and find the problem is a break in one of the ignition wires and replace it. Two months later he takes it to the dealer for a routine service - the dealer identifies the cable as an unauthorised modification, drops the car into their car-crushing machine, and explains to the owner that they were only acting to protect him from a possible accident should the third-party cable have failed while travelling at speed. They will not cover the cost of a replacement car, and he should be thankful that they are so concerned for his safety. He may, however, keep the mangled cube.
I think it's incredibly reckless to attempt this until the surgeon can perform the procedure on chimps with a reasonable level of reliability. But on the other hand, the patient has Werdnig-Hoffman disease - it's degenerative, he is already wheelchair-bound, and as the disease continues he is going to lose what little mobility he has along with his capacity to work. So if he wants to gamble his life on a kill-or-cure experimental and dangerous procedure, that's his choice. It might work, and if not then knowledge will be gained to improve the technique for the next guina pig.
That depends who the attackers are. If you're dealing with regular internet hackers, that may be true. If you're high enough profile to get noticed by nation-state hackers though, then they'll already have their ways of getting into any major cloud service - by means of warrant, threats or hacking - and you can't trust any hardware you don't have physical control over.
Hackers crack your server's authentication. The NSA just strolls over to Microsoft and waves a 'give us your data, tell no-one or you go to jail' letter. Or the FSB might do likewise, and point out that there are billions of dollars to be made in Russia and a company that doesn't cooperate with investigations may not be able to operate in the country. You get the idea.
Identify your threats, choose appropriate countermeasures. Chances are your organisation isn't going to merit the directed attentions of any state intelligence agency, so for the most part you don't have to worry about them - just the standard barrage of opportunistic script kiddies, ransomware, DDoS extortion, hactivists, spammers and all our favourite internet ne’er-do-wells. In which case, Azure or Amazon or some lesser-known cloud may well be more secure than your own team of non-specialists.
We do have the high-tensile-strength material - we just don't have a way to manufacture it in bulk and in consistent quality.
Big companies, pressure groups, politicians. America is the ultimate refinement of buzzword politics - to the point that an organisation can, by simply including the word 'family' in their name, immediately state their positions on abortion, healthcare reform, gay marriage, the role of religion in government and vice versa, non-discrimination law, regulation of obscenity and gun control.
