I have a cousin who is great at mathematics, and really can see mathematics as an art. Whereas I am happy if I can solve a problem, he will look for an "elegant solution". I had a number of equations that I solved, trying to optimise the buffer size for various input queues. I shown him, and he quickly said that I had the right answer. A day later he came and shown me how he derived an equation that could simply solve all problems of this type. He also generalised it to allow buffer sizes that were complex numbers. The first part was very useful to me, the second absolutely useless - but to him it was all just interesting.
This is one way that mathematics as an art is unlike any other art. It gives useful results. I have heard time and time again about engineers going to the mathematics department of a University asking how they can solve a "new" problem - to be told that the solution had been discovered a century before. I am sure most of these solutions came from someone just wanting to find an elegant way of expressing something without thought of any use. So if its an art and is useful why do so few people follow it?
The answer is obvious, because its hard! In many forms of art you can slap anything down and convince someone that it has value and its art. This may not always have been true, before photography accurate representational art was highly valued - but today someone producing a lifelike portrait will not be values as much as someone slapping their name on an unmade bed! Mathematics has to be right, you can't just slap down a few numbers and call it an equation. This is the basic problem that anyone will have in persuading someone to follow maths for its art, there are a lot easier ways to become an artist.
Road noise is wasted energy. Electric cars need to do everything they can to squeeze out the maximum range, so their tires are specifically designed to minimize noise. Any car will be noisy at highway speeds, but on an asphalt residential street where cars don't go very fast, an electric car can be nearly silent. Of course the speed at which you can easily hear the car is much higher than the speed it becomes dangerous, so this isn't complete nonsense.

While true you can make a lot of noise with very little power, particularly at higher frequencies. Anyone who has one of those battery-powered personal alarms can testify to that.
150pound pedestrian vs. 2000 pound vehicle.... they will NEVER win...
As a pedestrian... i know i'm damm sure paying attention to the large moving objects speeding around... it's a high priority not to be smashed.
Oh sure... the driver could be at fault... fat lot of good that does me when i'm dead..
I think you misunderstand the meaning of priority. The idea is that in places where they do it is the responsibility of the less vulnerable to give way to the vulnerable users. That's why its generally safer to cross at a pedestrian crossing.
Chances are they will enforce it strictly on everyone except Muslims who insist or wearing a kamize and hajib who will be told "of course wear what you want, our culture is subservient to yours"
This is not a troll. It is a commentary on the double standards which exist in the UK and other parts of Europe. They have a double standard for driver's license photos and for airport security for muslim women.
Correct. Some people are so used to giving way to Islam that they see any suggestion that we should hold Muslims to the same standards as anyone else as "islamaphobic". We ban Santa because more than one Muslim might be offended, but if two non-muslims said they were offended by an "Eid Murnbarak" poster how far do you think that would get. When Muslims set off bombs in our cities the call is not to stop Muslims setting off bombs but not to allow the incident to undermine multiculturalism! Muslims frequently burnbibles but go on the rampage when someone says they will burn the Qur'an - but doesn't!

That's the conscientious one. The regular guy will be like "Gotta get back to you later, sir, I am updating my status now".
But actually you should not read too much into it. This is just another money grab from the military -- they, and their contractor friends must be getting hungry on the lean offerings of Obama's budget.
In the British Army it would be "And he's like all get on and advance, and I'm like 'hang on man I got a crucial tweet', and he's like 'obey orders' and all that. Uncool innit man"
Its a well known affect. Logically you should worry as much about saving £50 when negotiating a house sale as when buying a £100 piece of software, but few people do. It also leads to the "marginal extra" situation which makes people buy more extras when making a big purchase. If I offered someone on the street a set of mud flaps for £50 and alloy wheels for £500 most would say no - but many would say "I might as well have the trim" when buying a £15,000 car!
The problem comes when there are only a few retailers left, many areas having only one close bye and they then put the prices up to a higher level than they were before.
If Anonymous is made up of random people who care about the issue of the moment, how do you investigate them over time? I can't see how they would all care about the same things, as it's not like Anonymous hires people to do stuff.
Unless there's some sort of "Anonymous Hacking, LLC" I haven't hear of...
Knowing Scotland Yard their answer will be to track and investigate everyone.
It is very general in some ways but contains odd specifics:
comprising: a unit that includes a processor operable to execute at least one high twitch-action video game, video game video being produced therefrom; a compression unit for compressing the video game video with a latency of less than approximately 80 ms, but greater than about 5 ms;
So the patent wouldn't cover latencies outside this range?
The set-top box of claim 10 wherein the wireless transceiver operates in the 5 GHz band.
Why this band only?
Ignoring these oddities I can't see much that isn't obvious - a box connecting by Wifi to a router connected to the internet for playing games.
Well, it's not like they're going to jump under a bus after having one beer. It's more like a token of sympathy which, along with supportive messages can go a long way in the other direction.
That's what I heard until I read that 90% of those sacked were Muslims, and the other 10% had connections with other terrorist groups.
For example, I feel relatively sure that "backdooring" security software would be not lawful.
I'm not sure if adding a backdoor in at the behest of the FBI in the interest of national security would be illegal in the USA. It might be, but it is certainly not obvious.
Basically, the idea is that bits of the key leak. And how is this accomplished?
For example - if a key bit is 0, you take one code path, if 1, another. Make the two paths different lengths. It may be possible to affect packet timing. Or... A function may end with "x - y" and then return "z". No leak? Not so clear, the carry/borrow may be leaking information to the caller (on x86 style hardware).
Anyway, it probably isn't a "back door", just some means of determining enough key bits to make brute force practical is enough. And this sort of thing can be subtle. It can even be based on the machine code generated for certain sequences by a particular compiler (the "x-y; return z" sequence above, for example).
I seem to remember a hacked version of GPG where all the hacking was in the keygen algorithm. Basically if you downloaded that version and generated secret keys you could interoperate with or even upgrade to a non-hacked version, but there was a flaw that not all the key bits were independent, you could brute-force an attack against a very small keyspace if you knew how the keygen worked.
the nasty effects on the ecosystem are inferior to the positive effect of the departure of humans.
Are you saying what I think you're saying?
Yes he is. Some people take the view that all lives, animal and human, are equally valuable. From that perverse perspective it is a logical conclusion that the Chernobyl disaster was a good thing. The problem is that you also have to conclude that you are being very selfish if you fail to provide a habitat for fleas, lice, and parasitic worms. I just hope he practices what he preaches.

We had the "green cross code: Stop, look, listen, think.
Well I don't like these ridiculous patent claims, but seeing Microsoft as a victim makes it worthwhile
