Why? Psystar doesn't build machines with Atom processors. More likely this is to kill the netbook OS X market, so that that group of uses will be desperate for something in a similar form factor when Apple releases the iTablet.
Space relay for power distribution makes a lot of sense for military/emergency purposes, but not generation. Why generate the power in space, when it can just be beamed up from a ground-station? We can extract useful energy far more easily at microwave frequencies than at visible light frequencies.
Absolutely. They missed the boat by 5-10 years. Had they started offering convenient digital services instead of stubbornly trying to protect their existing, entrenched businesses, they probably could have transitioned people into a new business model back when everybody was still used to paying through the nose for content. But no, that would require work, and vision, and why would you do that when you're making money hand over fist and the good times will never end?
So yeah, just another industry that failed to adapt to change when they had the opportunity. Well, you missed it buddy.
It works on a very simple principle, that is used in many devices sold today: the company that makes them probably kicks half the price back to the official who authorized the purchase.
Windows 7 has a whitelist (based on authenticode signatures) of programs which are allowed to automatically elevate. However, it also has mandatory access controls, which segregates programs into different integrity levels. When UAC elevates a program, it is placed in a high integrity level. Lower integrity levels aren't allowed to inject things like keystrokes into higher integrity levels.
So you are somewhat right, but mostly wrong. Malware could trick a trusted program into bypassing UAC and autoelevating, but after elevation the malware won't be able to interact with the trusted program anymore. And since all the trusted programs require a second user interaction before doing anything after elevation, tricking a part of Windows into auto-elevating doesn't help malware at all.
No, the solution is to abandon the ridiculous 'user privileges' model that's existed since the early days of UNIX. Running programs with the same permissions as the logged on user is a ridiculous security model. All software should, by default, be run in its own sandbox and only be granted access to shared resources (such as user documents) on an as-needed basis. Unfortunately, the software world is firmly entrenched in this horribly flawed model and it is unlikely to change any time in the next decade or two.
Not quite. Microsoft added a cryptographic whitelist of programs that are automatically allowed to elevate. Certain parts of Windows are then allowed to automatically elevate (like file properties dialogs, the control panel, etc...). Since there's no way to distinguish the source of events, NT 6.x also enforces mandatory access controls, and places programs with administrator privileges in a high integrity level, which prevents low integrity processes from interacting with them.
That's why some things still require two steps. The 'first click' causes explorer (or whatever part of Windows you're dealing with) to automatically elevate and switch to a high integrity level. But since that click could have been injected by unprivileged malware, rather than an actual mouse click, the program then requires a 'second click' confirmation. Since it's running at a high integrity level now, that second click can only come from other high privilege programs or drivers. One special case is the UAC settings control panel... that places itself into a high integrity level immediately so that malware can't inject keystrokes to turn off UAC.
Anyone who uses any computer (including Mac AND Linux) without anti-virus is asking for what they get.
Yeah? Can you point to ONE virus in the wild that has ever bitten any Mac or Linux user? Trojans don't count. Install Linux on your Windows box and you do NOT need any antivirus (unless you boot into the Windows side), provided you're not stupid enough to run an executable from an untrusted source.
That's more or less exactly the same situation in the Windows world. The only infections I've seen in the past 5 years are from people (or more commonly, their children) downloading dodgy stuff, usually from porn sites.
So 8/10 viruses don't require administrator permissions and conform to Windows development standards. If only the rest of the software industry had such high standards.
Where do these rights you allude to come from? Where are they enumerated?
If you want to make signing a contract which stipulates that the software will only be used in certain conditions a prerequisite for any software sale, that's your right. But last time I checked, I can buy a copy of OS X without signing anything whatsoever.
If you don't want me doing something with your software, you have the right to not sell it to me in the first place.
The App Store is not like a record store in a mall... in case you haven't noticed in real life you have choices.
The app store is like the state-run department store in some communist country, where everything is approved by the loving hand of the state lest you be exposed to anything counter-revolutionary. But don't worry, we have everything you need comrade! Ignore the capitalist scum, demanding freedom.
Ubuntu's crapware is epic. Take Evolution, for example. I never use Evolution, and I always want to get rid of it on a fresh install. But you try removing it on Ubuntu without jumping through a ton of hoops, and apt will happily annihilate your install. Same with all the crap they decide to install by default. It's a complete abuse of the package dependency system.
Except poverty lines are usually defined in some conveniently relative way. Until we start measuring poverty based on some universal standard, comparing countries based on the number of people below the poverty line is about as useful as phrenology is to comparative health care studies.
Rawls and the Veil of Ignorance are terribly flawed. It's justified by the minimax theorem from game theory, except minimax only holds true in zero-sum games, a condition which is patently false when we are discussing economics.
Frankly, the continued acceptance of the Veil of Ignorance in political 'science' circles is an embarrassment. For an outsider like me, the fact that they are collectively incapable of correcting a freshman mistake, seriously impugns the credibility of everyone in the field.
Nobody "stole" my password. I haven't used that account, or password, in the two years since I stopped playing. It's a little hard to get caught by a keylogger/phishing scheme when you haven't entered the account info anywhere in years.
The implementation seems buggy. I don't play WoW anymore, but I logged into my email this morning to find out some guy used the account migration stuff to link my inactive account to his battle.net account. Well, Blizz have never been good at getting things right the first time.
It may be a virtual autopsy today, but how long until we see something similar but as a diagnostic tool? It'll probably take another years to bring everything together (and 3d image reconstruction is still a computationally intensive task), but I can see something like this coupled with MRI and other diagnostic data from live patients. Fantastic.
I think you'd be shocked at how much thrust 5kN is, when continuous. 5kN would accelerate a 1 tonne space craft at 5m/s^2. That's 1% of the speed of light per week. With 5kN of continuous thrust you could visit Alpha Centauri in less than a decade.
Nice idea in theory. In practice, people have successfully sued others on numerous occasions after signing extensive statements about disclaimers of liability and agreements not to sue. Apparently on the basis that they didn't realize those documents were serious about it.

You recall wrong. NTFS has long supported both hard links and a mechanism called 'reparse points,' which are much more powerful than simple symlinks.

Who exactly is full of it? e-books != books.
e-books aren't covered under the VAT exception and you have to pay the full 15% on them.
I'm sure most /.ers actually filled that part in mentally when they read the summary.

What about the CA that issued a cert for *.secureconnection.cc? Do those ones bear any blame?
And it'll only cost ten times as much as SpaceX's solution! The ATV is a nice little vehicle, but it's a prestige project, not an economical one.
The RF field will be contained within the engine. Picture a faraday cage, inside out.
