The cooler uses a NaK alloy. Check youtube and you'll see that this reacts violently with water and will ignite in air. The company claims that they wouldn't worry about leaks in the cooler but I wouldn't trust them or want that stuff near my expensive hardware. The craziness of using NaK alloy as a coolant for a computer is probably why the company closed it's doors.
well in the case of your car i would not have called that a upgrade. i never herd of any automatic shift getting more mpg highway then a standard shift. automatics are for the lazy and i mean that once you know master a stick you drive it just as easily as a auto. really i prefer them because when they brake there cheap and easy to fix and a modern clutch will just as long as a auto anyways.
Check out VW's DSG. There's similar systems out there for other brands as well. They get more fuel efficiency than manuals and offer better shifting as well. BTW, F1 racing has switched over to systems like the DSG with paddle shifters a while ago. It's simply better than manual shifting.
>>>definitely an upgrade for the driver behind you, who has to stop accelerating each time you switch gears manually
Good shifters don't slow down. Professional shifters (raccar drivers) do it so fast you have to rewind the tape to see what the blur was. And of course good automatic drivers should stop following so damn close so they don't need to brake when I shift from 1 to 2 or 2 to 3.
Volkswagen comes with Direct-Shift-Gearing which has discrete gearing like a manual, but does the shifting by itself. That's what it gets +2 MPG on the highway (for diesels; gasoline car don't appear to have a difference).
Professional F1 drivers use paddle shifters on the steering wheel to shift. That's coupled with automated transmissions. No foot actuated clutch or anything similar. It's probably the best of both worlds although it's a bit more complicated and more expensive than either a manual or automatic.
I'm pretty sure promissory estoppel would cover that. Basically, if you make a promise or statement that you will do something then you can't sue people who rely on that and take actions based on that. So, the suits by the rightsholder down the road would very likely get squashed.
Becasue we as a society have determined that private enterprise can only exist at our discretion.

Where does either of these terms include being able to set up fictitious legal entities that have the same rights as people? People are totally welcome to start up businesses and take on the full liabilities for doing so. However, if you want to setup a corporation so that you can sell shares and sheild owners of the company from being sued for actions taken by the company or it's officiers than you're going to accept restrictions and requirements for being able to do this.
They're more power efficient if you're looking for high performance at reasonable power levels. The ARMs might be much better for tasks that don't need much computation but if you end up needing to combine a bunch of ARM boards into a cluster to get the performance you need then there's a lot of overhead that adds to the power consumption without giving you much.
You don't get to claim ownership but if you get to keep possession until the owner gives you a percentage of the vessel's worth as compensation for rescuing the boat, that's still pretty nice. I'd be fine with 10% of the value of that yacht for boarding it and bringing it back to shore. If the conditions are hazardous, you get more. However, this is according to wikipedia and you'd probably have to consult a maritime attorney to get a more definitive answer.
Do you have clean title?
Yeah, this is a bigger question than what is looks like
The parent isn't far off from the truth. I think salvage law would award a moderately large percentage (20-50%) of the value of the ship to anyone that boards and salvages the ship. Even a crappy boat would probably be worth six figures so any salvage crews could be looking at a decent amount of money if they succeed.
What seems to be missed in most of these discussions is that this network gear that the companies are buying are coming without software. One of the ODMs selling the gear appears to be moving to providing some software that can be put together to provide the necessary OS to do the networking but it sounds like it's still an effort to get it working.
If you're google, amazon, microsoft, etc., it's probably not too much of a problem to get a group of developers together to put together and maintain an OS to run the hardware but I don't really see many other companies deciding that they're going to put together a OS development group to save a few thousand dollars per router.
Does that mean that the kernel uploads the new microcode on boot ? How does it get it ?
The microcode module loads the microcode for the cpu from/lib/firmware/amd if it's newer than the one on the cpu. You can download and place new microcode updates from amd in this directory if needed or just let your distro provider update the microcode files when they push new packages out.
Well, you really shouldn't be debugging code on petabyte datasets to begin with. If there's a bug that shows, there's a minimal dataset on which the bug shows, and that's the dataset you can ask help with.
In general, you should always develop code on a tiny sample of the dataset. Once it's fully debugged and works correctly, then you apply it on your petabyte dataset.
Some bugs and issues don't show up until you get to a certain scale. Consider race conditions that only occur so often, unless you hit a certain scale you may never see it. To give a another pertinent example consider something that corrupts one byte in a PB (maybe it's a very infrequent condition or something), until your dataset grows to multiple PB, you may not even see it. Or consider the issue that occurs on raid arrays where you get a second drive failure when rebuilding an array after a drive has failed and been replaced. Until individual drives have enough data that rebuilding the array takes a significant amount of time, you'll probably never see this failure scenario and your code may not even be aware that this is something it needs to be able to handle.
OTOH I'm sure hadoop and friends would be very useful for the LHC and other big science projects, but they have are mostly taxpayer funded and are fighting to keep the dollars they're getting, not looking for new ways to spend it.
HDFS is already used by CMS (one of the detectors at the LHC) to store and manage distributed filesystems at various regional centers. After all, when you are generating multiple petabytes each year and need to process it and keep various subsets of it around for analysis by various groups, you need filesystems that can handle multiple PB of files. And yes, I believe patches are being fed upstream as necessary. Other filesystems being used in the US include lustre, dcache, and xrootdfs.
Although funding is an issue, continuing to run and analyze data from the LHC means that money needs to be spent to buy more storage and servers as needed and to pay people to develop and maintain the systems needed to distribute and analyze all the data being generated . Having multiple PB of particle collision data is useless if you can't analyze it and look for interesting events.
It's called population control, if you are stupid enough to ingest snake oil without knowing all the side effects, Darwinism has chosen you.
How do you know the side effects without the FDA forcing the manufacturer to test the drug. Hell, some side effects don't show up until tens of thousands of people have been taking a drug or class of drugs for years and database to monitor drugs being prescribed gets mined for correlations between prescriptions and side effects.
The worst that can happen is you spend $50k on a treatment that doesn't buy you a single god-damned day of further life. Now, not only are you dead, but you get to go to your grave knowing that you've heaped an extra burden on your loved ones for nothing. But since at the time of making the decision you're still in the bargaining stage of grief, you don't think about that. The heartless scammers running these cons count on that.
Nope, the worst that can happen is that you get a reaction or other problem from the stem cell treatment and die from the treatment possibly fairly quickly after the treatment. So a patient with something that might have been chronic but manageable or treatable ends up dying prematurely. Stem cells can cause cancers or do other bad things such as develop into the wrong type of tissue (e.g. bone tissue in the middle of an organ), the trick is getting them to turn into the right type of tissue in the right places and to prevent them from multiplying out of control.
But the range is the key. If your adversary is standing off 100,000 km away - halfway to the Moon, then throwing rocks at them is futile. Your only chance of attacking them in anything less than glacial time is with lightspeed.
The faster that any kinetic weapons travel, the greater the energy needed to alter trajectory. That needs more fuel, more weight and therefore they represent a larger target, themselves - and the fewer of them a capital vessel could support/contain. However a 200MW reactor (roughly Typhoon submarine class), suitable shielded for thermal emissions could power a nice big laser canon in pulse mode (provided the crew are prepared to hold their breath for a few seconds while the capacitor bank charges up).
So far as detecting emissions goes, you can only detect those emitted in your direction. If all the heat/IR is directed away from the "battlefield" it's invisible to anyone not in its path.
Alright, how do you dump the heat from that 200MW reactor? You're going to need a lot of surface area to radiate the waste heat for that away so that your spaceship doesn't overheat and kill everyone on board. And that's just for the weapon system. You also neglect to consider beam divergence. Your laser will expand in size as it travels so unless you have very good optics , you'll be range limited unless you dump massive amounts of power into the laser.
Finally, unless you have some sort of system that will subvert the laws of thermodynamics, you can't direct the heat away from others. Parts of the spaceship will have a temperature above 3K or even 50K due to thermal conduction. Given that the various cosmic microwave background surveys are able to send up satellites that can detect variations in the CMB of less than 0.001K in a background of ~2.7K , any physically realizable ship is going to stand out pretty clearly regardless of what stealth technologies it uses.
That's tough enough to do when all the processors use the same instruction set, but if the system has processors with different instruction sets, it makes it much harder to have the OS/system switch from a lower powered mode where it's running on the ARM processors to a high performance mode where it's running on the x86 processors. It's not impossible, it's just very complicated and I don't see companies lining up to do the work to implement something like that.
You could theoretically just release something and say "I promise I won't sue you if you redistribute this" but that is not legally enforceable. Which means as a person or company interested in using your work, I should be extremely wary, since you could easily and legally just change your mind and screw me over.
It is legally enforceable. Look up promissory estoppel. Basically it's a legal doctrine that says that if someone makes a representation or promise to you regarding something and you take action based on that promise, that person can't sue you for acting on that promise. E.g. if you release something and promise not to sue anyone for redistribution, then legally you no longer have the right to sue anyone for redistribution.
Let me ask you, are MRIs something you consider useful? The work done by scientists to get the superconducting magnets setup and working on the tevatron resulted in knowledge and skills needed to make the superconducting magnets used in MRI systems. The work at the LHC provides cutting edge experience working with superconducting magnets and power systems, ultrahigh speed electronics, distributed storage and computing systems, high bandwidth networking and that's aside from the purely scientific benefits. If you design and build something that requires cutting edge electronics, and cryogenics to work and produces a few petabytes of data each year that needs to be distributed internationally and processed, you'll get a lot of experience and new technologies that probably come in handy for non-science related things as well.
And what does their food amount per day or length have to do with me visiting there? If anything, I help the general population by visiting there. Sure, that 2000-3000 euros it costs me to do so doesn't matter much, but the people get to see more people from foreign countries. Maybe it indirectly helps in something, I don't know. What have you done, exactly? And again, as I've previously noticed how people (especially those from US) tell how other nationals are suffering so and so much, and when I've visited there it's been nothing like that, I don't really take everything I read on the internet not so seriously. Usually the people are happy, and would be unhappy if things were different. Other people, especially US ones, for some reason like to think they "know better" and try to impose their views on others.
You're not going to be helping the general population by visiting. The money you spend goes directly to the north korean government and not the people. It's not as if your guide/escort is going to let you interact significantly with the average person or buy anything from them.
If you look at reports and studies by a variety of sources (south korean, us, UN, NGO, chinese, etc), they all pretty much paint similar pictures of what's happening in north korean. I suppose everyone could be lying and you magically have the truth of the situation but it's doubtful. Based on a reasonable interpretation of the reports and evidence, the north koreans do have it pretty bad and aren't doing fine and wouldn't be unhappy if things changed. Honestly, it sounds like you're willfully blinding yourself to the evidence out there or are hopelessly naive.
Are you seriously comparing whole North Korea to concentration camp in Hitler's Germany? Frankly, it's not like that. While it's true that Kim Jong is the sole leader of the country, it's not really that bad for the people there. They have it much like rest of the world, and people seem really happy. Sure, some of it comes from the fact that they don't know better, but to compare it to concentration camp is ludicrous.
It sounds like you'd be fine with visiting Cambodia under the Khmer Rouge or Soviet gulags as well. Between 1990-1997 Korea lost between 5-12% of the population to starvation with the military getting preferential treatment in regards to food rations and everyone else being effectively left to fend for themselves. North Korea is still suffering from famine and according to reports people are getting about 700 calories a day of food. Also, north koreans are apparently about five inches shorter on average than equivalent south koreans.
Either you're woefully misinformed about the situation in North Korea or you're intentionally blinding yourself to it or you simply don't care. If the problem is the former, I'd suggest reading up on things before saying that things are fine and dandy. If it's the latter, well, you should spend time trying to find some compassion and humanity within yourself instead of traveling so much.
Still not random. If you can (and I am glad to admit this is impossible hard as far as I know) capture the 'surroundings' one on one, this is still not random enough. But still a good read and link.
'Capturing the surroundings' still won't help you do any predictions for sources with quantum randomness. At best you can say that a source would exhibit a certain behaviour x% of the time. Quantum systems are not deterministic so even with perfect state information, you can only give probabilities that certain things happen. If you know otherwise, feel free to let others know and collect your nobel prize(s).
Newton's laws of motion are pretty well defined and accepted. Momentum increases as the square of the velocity. You'd have to be really outside the norm to think otherwise. So, applying that science to automotive policy, speed limits should be as low as possible. Five MPH at most. Double that limit to ten and you've multiplied the momentum by 4 and the amount of damage by the same. Maybe even 5MPH is too much!
Newton's laws of motion don't discuss momentum at all. Also momentum does not increase as the square of velocity, in newtonian mechanics, p=mv so momentum increases proportionally to velocity. Kinetic energy increases as the square of velocity (k=.5*mv^2). But even that doesn't really determine how bad an accident is since you need to know how elastic the collusion is and the impulse since those tend to be better indicators of the severity.

Correct me if I'm wrong, but salvage law only begins to apply when a vessel has sunk.
Nope, from my understanding it also applies to ships in distress or which are sinking or those that have been abandoned.
