Why not? A simple plastic one should suffice. It's not like most people use it.
It will be the people with religious, political, and moral objections that will be the first ones to have their brains replaced (or at least modified) anyway.
I agree with the theory. Parents should be the ones deciding what their under 18yo children get up to.
But, it is illegal to sell alcohol and cigarettes to 'minors', and there are bunch of other drugs that are illegal to sell to anyone, and if the number of underage drinkers and smokers are anything to go by, this law on its own is going to do squat. And as most kids view software as 'free as in beer', whether they can 'buy' it or not is mostly beside the point:)
I second that. Dead easy to set up, and does almost everything you could want.
The one and only 'gotcha' I found, is in situations where PTMU isn't working right and you are using compression on the tunnel packets. The MTU of the tunnel thinks it's 1500, but it should really be 1500 less the tunnel overhead. A ping shows that a 1500 byte packet gets though, but only because it's easily compressible data. When you start moving actual data around suddenly connections hang for no readily obvious reason. It could send a nerd mad!
Just out of curiosity, how did the power usage and heat compare to the alternative?

I played that through on the PC years ago. Absolutely amazing game, very clever puzzles and graphics that weren't exactly beautiful but still quite stunning and very very functional.
It didn't really have any re-playability for me though, and I never really looked at the 'sequal'.
but you can't mount a Xen domU filesystem in Dom0 when a DomU is using it
Can and do:). Use OCFS2, piece of cake to set up and the because Xen 3.0.2 is based on 2.6.16, it's already in the kernel tree.
Haven't used it as the root filesystem yet (just as a shared filesystem between domains), but when I do I will (in theory) be able to have 1 filesystem with 'per node symlinks' (ocfs2 calls them something else but that's what they are) so each node/domain can have a separate/etc,/var/run,/var/spool, and so on.
You can kill someone with a car and get less time in jail than if you did it with a gun.
I think the difference here is intent. Much easier to prove intent if you point a gun at someone... afterall why do you have a gun unless you plan to use it (I live in Australia).
But, along the same lines, take two people with similar illegal levels of alcohol in their blood. They both drive home. They both run a red light. In running the red light, one of them runs down and kills a pedestrian.
Assuming both were drunk enough to not notice a pedestrian right in front of them, and it was just (bad) luck that someone was crossing at the traffic lights at that exact moment, is the one who killed the pedestrian really any more guilty than the one that didn't? Should the size of the sentence really take that 'luck' quantity into account?
I think that maybe the justice system is more focused on seeing 'justice done' rather than making the world a better place.
The panic reaction in a front wheel drive is the safe one, turn the wheel the way you want to go and floor it
I used to own a '63 Morris 850 (Mini), which I used to drive too fast for my own good.
If you turn the wheel and floor it and retain traction on the front wheels then the car will pull you round the corner just like you want it to.
If you turn the wheel and floor it and the front wheels start spinning relative to the ground (eg because it's wet or because you've got enough torque to break traction), then you'll pretty much just keep going straight ahead. Try it some time before you need to rely on it.
The latter is why ABS and traction control are such a good idea. The moment your front wheels start sliding, you almost can't steer (slightly different in the dirt of course).
Also, just because it's front wheel drive doesn't mean the back can't slide out on you. The back end of most small front wheel drive hatchbacks is pretty light.
It might depend on the implementation of ABS, but as a driver you have 1 brake pedal and 4 wheels. Your cars non-ABS braking system should be tuned to proportion braking force applied to the wheels so that in a straight line with an average load in average conditions, the point between wheel lockup is roughly about the same for all four wheels.
As soon as you put in a few more passengers, have a bit of extra wear on one of the tyres, or turn a corner, one wheel is going to lock up before the others for a given pressure on the brake pedal, and so as a driver the best you can do is stop that one wheel locking up, which means the other 3 are no longer applying the maximum amount of non-locking-up force.
A decent implementation of ABS will apply the maximum force to each wheel without locking it up, acting as a trained driver with 1 brake pedal per wheel. Having 1 brake pedal for all 4 wheels is a compromise.
That said, there are times when you need to skid to stop in a hurry, and ABS is never going to be able to tell. But that's what the hand brake is for:)
If the decoder module was renewed frequently (yearly, monthly, whatever) then the race becomes a bit harder. There are two challenges then: 1. Brute force the private key. It would need to be done fairly quickly though (not much use really if it takes 5 months to get it when the module is renewed semesterly). Key strength could easily be increased to keep the discovery time sufficiently long, as the decryption is completely contained within the device. 2. Find a way to trick the module to give up the private key by: 2a. Exploiting a flaw in the device. Easy to fix at the next issue. 2b. Physical analysis (xray, whatever) to extract the key (assuming the previous issue device is the same design as the current one and the steps to discover the key last time can be followed much faster). A bit of obfuscated variation at each device issue would take care of that.
because you are handing over the ciphertext, the plaintext and last but not least the key over to your adversary
Does it really have to be this way? What if a central body developed a chip whose interface is known but whose internals are highly secret. Anyone making playback equipment just has to be able to accept one of these chips.
The function of the chip is to take an encrypted content stream and give out an unencrypted content stream.
Hmmm... even as I write this I can see that it's absolutely full of holes... I've just given you a single component that you can simply plug into your own decryption device:)
It's just like 'perfect' copy protection on CD's. Impossible to achieve by definition.
I guess the only way around this is: 1. actually make content that people will pay for 2. don't charge them too much for it (eg no more than what you'd pay to rent it anyway) 3. make it easy for them to pay for it (this is important!) 4. once they've paid for it, don't restrict how they use it (eg you can only watch this on xyz device) 4a. use an 'open' codec, and if none exists, make one and make it open. 4b. make sure it is dead easy for people to self audit 5. let people distribute the actual content to each other (if #2 and #3 are true, you still get revenue and you don't have to futz around with content distribution systems. Let everyone else pay for the bandwidth) 6. Impose heavy (but not directly financial) penalties on people who infringe in bulk (you've paid thousands of $$$ on a home entertainment system but won't pay $3 for a movie??? you get what you fscking deserve. We'll take that $$$ home entertainment system thanks:)
The wikipedia does lack some of the unnecessary fluff, bit it seems a bit shorter on anything outside the pure technical details of the hardware. eg
[TVT article] It was the star of the convention and even though Ampex had set a selling price of $45,000 for production models (more than $320,000 in 2006 dollars), orders were written that week for more than 70 machines. (Market research conducted prior to the show indicated that there would be a demand for no more than a dozen globally.) and Even so, sales orders were being written on an almost non-stop basis. According to one source, Ampex ran out of sales forms and was writing orders on any scrap of paper they had at hand.
[wikipedia] Both demonstrations were a success, and as a result, Ampex was swamped with orders for the new 2 inch Quad VTR.
There do appear to be details in the tvt article that are interesting but missing from the wikipedia article.
I assumed by the title that there had been some sort of bust and domains had become worthless, given that a domain name is nothing more than a pattern of data on a disk, and that the pattern on the media weighs nothing(*).
But obviously the opposite is true. The next big thing will be businesses whose names are created by a random trigraph generator or are corruptions on existing words.
In Australia.com.au's have to provide evidence of registered company names, so in theory we don't have such a problem with.com.au domains names.

Maybe it would have made a little more sense if they said you could hang three cars(*) off of a quarter. Not quantative by any means but give's an approximate idea of it's strength.

Deliverable would mean (roughly) a unit of work in a project which, when completed, can be delivered to the customer and be useful to them. Product in no way means the same thing. It is also a word whose meaning could be pretty quickly derived even if you hadn't heard it used in that context before.
It is the only word I picked up on in the article summary that wasn't just a longer word that 'laypersons' wouldn't understand used in place of a shorter word that everyone understands, which is what corporate speak is all about.
Of course if you get your electricity from a renewable source then this is not a problem
I'm not sure I agree with the above statement. Unless the supply of 'green' electricity totally covers demand, every unit of electricity you save is one unit less that has to come from 'non green' sources, even if the electricity _you_ are using is completely 'green'.
Of course this is no reason not to use 'green' electricity, just that saving electicity is always worthwhile.
You've obviously never suffered from dental pain have you? (Or you've forgotten how much it hurts. Memory of pain is like that)
You'll find that most 'normal' (non-prescription and low-end prescription) drugs don't do a lot for you, and anything that might relieve the pain starts to seem like a good idea, even if it involves someone tinkering inside your mouth with a rock:)
Assuming you see your dentist regularly, your cavities should be spotted before they get anywhere near a nerve. I suspect that dentists give pain killers just in case the hole is deeper than it lokos, or in case they slip, and that in most cases wouldn't be required.

A guy I used to work with was mostly blind in one of his eyes. He had a 'lazy eye' condition as a child that was never picked up and corrected (eg glasses with sticky tape over one of the lenses). If your brain can't match the 'signal' from both eyes (eg from a turned eye, or just because it doesn't feel like it), it basically just stops processing the signal.
