Cheap solution:
- Buy an atom-based motherboard with SATA and PCI slots (Since it's a home server, you probably won't need a beefier CPU.)
- Put SATA cards in said PCI slots
- Put it in a huge case, invest in hard disks
You can easily get a NAS with six SATA drives that will run at less than 200 watts (you can save a lot there if you have drives spin-down while idle, but I'm told this reduces their lifetime.)
I have a similar machine set up in my closet serving up 2TB of space to my network. It costs about $5/month in energy to keep it on 24/7.
It is spelled sudo in the game (it's spelled that way in the subtitles.) Legion is the character who says it. The only time I encountered that line was when he was hacking into a turret.
You might check in with your local county. A few weeks ago, I heard about the IT department in my county making some big changes in the way their network is run, so I volunteered to help out. It was about half physical moving and organizing of equipment and half technical work. IT isn't actually my field, but I knew enough of it to be a help rather than a hindrance. It may be the case that your county doesn't need your help with IT, but they're certain to have something with which you can help out.
Like others have said, DD-WRT is for consumer grade hardware. Since DD-WRT is closed-source, you can't recompile it for anything else. However, nothing is stopping anyone from taking the OpenWRT source and compiling it for a more powerful router.
Oops, forgot to add the footnote:
* Exceptions are books in areas such as algebra, calculus, and basic physics. Those tend to not change very much at all.
You're comparing apples to oranges here. The submitter of the story is talking about a ten year old textbook in computer science. You, on the other hand, are talking about fiction. Updates to textbooks usually* contain new and useful information that makes them better choices than old versions. Slight changes to a fictional story tend to add no value whatsoever. The best advice that I can give the author is to come out with a new and up-to-date edition of his book. That and try to be competitive; as it stands, I'd rather get MacKay's e-book on the same subject since it's both free and more current.
You seem to be confused as to what I was referring to with "the textbooks", I should have clarified. "the textbooks" in this case refer to the textbooks being written for this program, not any textbook you can pick up off of the shelf. The point that I was making is that this project can correctly be called open source if both the compiled document and the LaTeX code are released to the public. If they are indeed making the textbook freely available, it would seem logical to also release the source of the book. I'm not saying that is exactly what will happen, or even close to it, but in this case it would not be inappropriate to apply the open source label.
The only problem with what you say is that the textbooks that are currently published do not have their LaTeX source published for free for anyone to change. This is what makes them "closed source" textbooks. Specifically, it's your second bullet point that has a problem. You left out the bit where the source (LaTeX) is also made freely available to anyone who wants it.
Well, if they're planning on writing the textbooks with LaTeX (I'm told that this is common in publishing), then the open source label would most definitely apply.
I have to second this. Webmin has everything you ask for and then some. If you have an update script on each machine, you could easily update all of your machines at once with the cluster management tools. I know it works well with APT (having used it myself), but I can't speak for any of the other package managers. In the worst case, it's still easy to push an update command to the non-apt machines through the Webmin cluster tools.
English is also not derived from Latin (although it does borrow a large amount of words from Latin.) Swedish and English actually come from the same language family (Germanic) and share a large number of words (whether they share more than English shares with Latin is something that I don't know.) By the hypothesis you mentioned, the concept of habeus corpus is not something that English speakers should be able to conceptualize either.
It doesn't seem like such a good idea to integrate an RFID reader into the tablet as a security device. Any hospital that can afford equipment like this will probably have tons of people walking down the hall with RFIDs that can grant access to these things. The only way that this could really add to the security is if it's part of some multiple authentication system (i.e. require two methods of authentication to log in out of three, but even that sounds like a bad idea.)
There was also no mention of any encryption of the medical records stored on these things. I definitely wouldn't trust Windows permissions to keep the records on these safe. Don't get me wrong, I think this is a great step toward making hospitals more efficient, but they need to be secure or they'll just be a liability.
If you ionize something, it does not become radioactive, it becomes charged. Chances are that it'll leave a bunch of high-energy electrons wizzing around, but that won't last long (they'll find something to recombine with very quickly.) High-energy photons like gamma rays also don't stick around too long. Things like unreacted plutonium, however, do stick around for a long time and they do produce gamma rays over an extended period of time. Antimatter would definitely be cleaner, but there's the sticky issue of the cost of producing it and storing it (you can't just put it in a jar, once it touches matter it'll release all of the energy of its rest mass.)
Well, a guitar and a bass have a different number of strings, which (IIRC) are not the same sequence of notes (tuned in fifths and fourths, respectively.) So you can't necessarily play one if you play the other.
I never said that providing jobs was the purpose of the companies. The purpose is indeed to make profit. Being able to provide jobs is just how a company can give back to the economy. As for your question, HP makes about $80 Billion more than Apple while employing more people (numbers are above in case you didn't see them.) I haven't seen any reason why that's a bad thing.
It depends on what you're going to use said small and quiet computer for. If it's just web browsing and other low-powered tasks, the damn small linux developers sell pre-installed computers about the size of a wii that are completely silent and all $200-$450. If it's something more high-powered, look for barebone systems with small form factors (Shuttle has some good stuff in the $500-$700 range.)
There is a limit to how much current superconductors can carry before they become non-superconducting (depends on the material and the cross-section of the specific chunk of material.) A strong superconductor will be able to carry more electrons while remaining in the superconducting phase.
Almost, but not exactly. You mentioned two different quantum cryptographic schemes. Greatly simplified they are as follows:
The first scheme involves sending single polarized photons through an optical medium (such as a fiber optic cable) to a recipient who will then measure the polarization of the photon. There are two possible ways to send and measure the photon (X scheme and + scheme.) If the same scheme that was used to send the photon is used to measure it, the recipient will (ignoring errors introduced by the optical medium) always measure the correct result. If the recipient uses the wrong measurement scheme, they will have a 50/50 chance of measuring the correct result. When enough photons have been exchanged, the sender and recipient discuss over a public channel what measurement schemes they used. Any time that they did not use the same measurement scheme, they both discard whatever bit was measured. Through error checking and disclosing a few bits (which are later discarded), they end up with a perfectly secure, random sequence of bits. Eavesdroppers usually introduce a large error to this process, and are easy to detect. This is the one that the device in TFA is useful for.
I'm not well versed in the second scheme, but it has a dual measurement setup similar to the first scheme. Essentially, two entangled photons are created by the sender (or third party.) The sender keeps one photon and another is sent to a recipient. They both use one of two schemes to measure the photons. If they both use the same scheme, their results are highly (but not perfectly) correlated. AFAIK, the device in TFA cannot produce entangled photons, since it only produces one at a time, and is useless for this scheme.

Vista CD Key, that's only one.

$1 Billion in sales. WoW makes its money through subscriptions, which are not sales.
SphereXP is another 3D desktop that comes to mind as prior art.
If you want to read it but don't want to show support for Card by buying it, try borrowing a copy from your local library.

You've obviously never ridden in a city like San Francisco.
