And as soon as they pop up, they get invalidated by newer hardware and newer media. HDMI/HDCP has the ability to push out key revocation to existing hardware and spread to other connected devices.
Use it to bypass HDCP issues where two devices are unwilling to talk to each other. Use it to bypass ICT (image constraint token) or SO (selective output). Use it for DVRs that are incapable of complying with CableLabs' restrictions, or in other locales which have no conditional access mechanism. Use it for any number of other legitimate fair use reasons that don't involve content piracy or copyright infringement.
You see those flu vaccines, how they are good for a couple different strains, and there are tons of others they don't protect against? Viruses mutate, and do so very rapidly. Give them something to survive in, and eventually they will mutate into something that no longer resembles the vaccine sufficiently closely for the vaccine to be effective. At such time, a new one must be developed.
If you inoculate the entire population, or a sufficiently large percentage, you effectively eradicate the virus. If instead, you let those periodic outbreaks flush though the unvaccinated, your probability of a mutation continues to grow.
So someone comes up with a working product capable of keyless, real-time HDCP decryption, and the first thing you want to do is use it to throw content up on bittorrent. You see, this is why the rest of us can't have nice things...
Immunization doesn't take for everyone. Immunizations can't be used on everyone due to things like allergies. Immunization can wear off and become ineffective over time, or in between booster shots. When everyone is vaccinated according to schedule, you only have a small percentage of the population that is at risk to those diseases. Since there are only a couple percent that will become infected when exposed, the likelihood of the virus being passed between two of these people is very low. It is a condition called "herd immunity" that makes unchecked spread of the virus unlikely.
When people are willingly forgoing vaccinations, you aren't just putting yourself at risk, you are dropping the total percent of the population that is at risk. As that number drops further and further, the easier it is for the virus to spread into an outbreak. The more a virus spreads, the higher likelihood it will have a chance to mutate into a form the existing vaccine does not protect against. In other words, when they chose not to get vaccinated, they are putting all the rest of us at risk out of their own stupidity.
Except... vaccines train their immune system. That's what they do. That's all they do. That is their entire purpose for being invented in the first place. You expose your child to an inert or approximate form of the virus, so they develop antibodies to it and their immune system can there after fight it off should it ever be exposed to it.
Actually, no I don't, because that's not how microwave ovens work. The resonance situation you are referring to only occurs in water vapor, not liquid, and then only at much higher frequencies. Microwaves operate by causing polar molecules, such as water, to repeatedly flip back and forth in an oscillating magnetic field. These spinning molecules impact each other, resulting in heat.
The bigger issue is that your eyes constitute a large volume of polar liquids with relatively little contact surface to conduct heat away, and no circulation. Where other parts of your body may be similarly affected by RF, your eyes have very little ability to cool themselves, meaning the sustained radiative energy they can accept is much lower.
Supercomputer workloads are not embarrassingly parallel problems. For those tasks, you use a much cheaper grid computer, connected through gigabit ethernet, or even over the internet. By definition, embarrassingly parallel problems need relatively little communication, so there is no sense wasting the extremely high end interconnects you find on supercomputers for such problems.
Writing AV software that can discover new viruses without being programmed to is tantamount to artificial intelligence. Sure, AV software has incorporated some form of heuristic analysis for a decade, but it is limited, power hungry, and prone to failure. If it actually worked well, then viruses wouldn't be the huge problem that they are today.
Oh come on. The only way you could make it so AV was not a requirement would be to cut out a couple hundred million lines of code, and disconnect the network cable. You can't make a complex piece of software without making mistakes somewhere along the way. Those mistakes can be exploited, and then it just depends on whether you're a sufficiently large target to be worth going after. Look at how commonly Linux servers on the internet are compromised.
There is no doubt they made some poor design decisions in the past, but raising the bar will do nothing to prevent virus and malware creators from attacking the low hanging users.
Today there are many different reactive AV solutions, and it is damn simple to evade them all. You need only modify the virus sufficiently that it is no longer recognized by the virus definition files, and recompile. All AV software can do is get a copy of the new variant, and update their definitions to suit. That's why you have to get a subscription and frequently update your AV software.
As well, there are common traffic situations where visibility doesn't really help yet size hurts. Say a car suddenly cuts into your lane. You either swerve and rollover, or step on the breaks, and guess what, because of your increased mass you cannot stop in time and run into the car in front of you. This is yet another way in which driving a larger car increases the chances of injury.
You missed one. You step on the gas to clip their rear quarter as they come over, destabilizing them, and putting them into the wall. After all, just because you're driving slow in the left lane doesn't give someone the right to pass you.
And yes, this happens. Literally one week ago I was hit on my bike by a car when I was crossing a crosswalk. I had the right-of-way, I was in the crosswalk, and I was fucking visible. I was not in violation of anything when I was crossing that street.
Actually, you were. Around here, sidewalks and crosswalks are for pedestrians. If you got off your bike and walked it across the street, you would have been fine. If you were on your bike, you should have been in the street, waiting at that red light.
In college, I lived three blocks from a natural gas fired tri-generation steam plant rated at 25MW electric, 70MW thermal, and 18000 tons of refrigeration. If you weren't paying attention, you wouldn't even know it was a power plant.
Admittedly, "full load with everything running" includes several hundred each of P4s, single core AMD64s, dual core AMD64s, Core2Duos, and a smattering of i7s. The older single core boxes are rarely even turned on any longer.
Toledo only needs 260 kW electric and 100 tons of cooling, much too small for a traditional gas turbine.
Yikes. We've got that much power run to our little compute cluster servicing half a dozen graduate students. We've got a pair of 400A 2-phase 220V panels for our computers, and about as much running to a pair of AC units. Under full load with everything running, we might hit half that. The combustion lab at the other end of the building runs a pair of 800A 3-phase 480V service lines to power resistance heaters for their high pressure air tanks. The lab back on main campus uses around 2MW of steam from the local co-gen plant for their supersonic wind tunnel.
Amusingly, with better than a megawatt of capacity, our off campus facility is still stuck with lousy business class RoadRunner that goes down at least twice a week, with DNS troubles far more often.
He said "for a server". While the PicoPSUs are fine for a desktop with modest graphics, they're not going to do much for a multiprocessor server. Besides which, 12V at 50+A is some nasty stuff. You would be better with telco grade -48V hardware if you have to pass a significant amount of power.
For shaft power, the large scale turbine running at higher pressures and temperatures, with fancy intercooling and heat exchangers, is going to provide much higher efficiency than a small one. If the waste heat from the small scale turbines is used to run chillers or boilers, the total thermal efficiency of the whole system can be higher than a larger shaft-power-only turbine. Of course, there is nothing preventing the larger turbine from being hooked into a similar combined cycle system as well.
Traditional gas turbine generators run 5-10MW for small ones, up to 100MW for large ones. In this case, a microturbine would be something small on 10-100kW. Note that a large automotive turbocharger is capable of 100kW or more. On the plus side, multiple smaller units means a more redundant system with less overhead. On the minus side, several small turbines is both more expensive and less efficient than one large one of the same output. It would be cheaper to just go with two large turbines, each capable of handling the full power load of the server farm.
This is actually the complete opposite of that. The bomb uses the inertia of its 25klbs of non-explosive mass to penetrate through ground and re-enforced concrete, to deliver the high explosive to an internal tunnel before detonation.
I saw no such wording in the LA Times article. Why would you even bother? The bomb weighs 30klbs, 25klbs of which are the dense penetrator designed to get the warhead down to a depth that it can actually damage the complex. If you were going nuclear, you would forgo all that weight, and use a couple MT airburst to crush the complex from the surface.
I think the idea is that you use the software to churn out tons of small patches of potential matches, which then get passed out to the humans for verification. If the humans score the patch highly, those used pieces are considered spent, and down-weighted from any further matches, while the software bumps up to the next level and starts weaving together the larger patches.
Since the software is only making small patches, the number of combinations stays within manageable levels, and the humans are better at spotting patterns and words to suggest the patch is a valid match.

Fishes are pretty carnivorous.
Pretty sure most are omnivorous. They're like goats or chickens... if it looks anything remotely like food, they eat it.
Just because it goes down their throat doesn't necessarily mean they can digest it.
