...it sounds like an embedded-Linux hackers favorite new toy.
Forget embedded-Linux hackers, I'll be buying it for my (then) three year-old! Seriously, that ought to be the best (learning) toy you can get for a young child: cool, pretty and robust. What more can you ask?
The real genius here is Isaac Newton. 'course, that's not news to anyone.
You mean that Newton thought about taking advantage of the IEEE float format to initialize the algorithm using "i = 0x5f3759df - (i>>1);"? Wow, now that's a clever guy!
The Absolute Sound which explained why a copy of a music CD sounded better than the original on the same equipment.
That's easy. You start with a Celine Dion CD, you copy it into a bad cassette tape, then capture it with your soundcard (and forget to un-mute the line in), and finally you burn it to a CD. The new CD will definitely sound *much* better than the original.
I see you're not a real connoisseur. My 500$ digital video cable makes the red, green and blue so much richer. It also makes the programs I'm watching subtly more entertaining. You see, that's because the bits are happier when traveling an expensive cable.
Have a look at the (pre-SSE) x87. The performance is still about the same as for integers (two pipelines, about one result per cycle each). Comparing to ARM isn't fair because it doesn't have an FPU. For newer CPUs that have an FPU, integer performance is about the same as float. I'm not sure if GPUs can do integer, but if they do, their integer implementation is probably also much faster than the CPU's integer arithmetic. So it's not about int vs float, it's all about general-purpose vs. specially optimized for (vector) number crunching.
We know the CPU is wonderful at computing integer math, but it's always been lacking in floating point.
Actually, recent CPUs are already at least as fast doing floating point than integer. The difference is that the GPU has massively parallel capabilities.
Sure, when (if ever) the US does that, part of my point will be moot. Remind me when that happens.
Oh, I've also got enough deuterium and tritium from the water of my bathtub power my house for the year. I'm canceling the electricity company right now!
Consider that the US produces ~25% of the world's greenhouse gases. I don't think its trees can remove anywhere near that proportion. From what I heard (but I could be wrong on that one), the US has enough land to sustain only about 1/10 of it's population considering its current way of life.
Dunno, they could build a giant, 50km tall wall all around the US... which in turns would help a lot reducing global warming (in the rest of the world that is).:-)
here in California a large fraction of drivers can't even read the signs
I've been to Germany once and couldn't read German. Not that big of a deal because it's almost entirely pictograms, unlike the US and Australia where they have signs that say "You know, it might be a good idea if you happened to stop on this corner" (OK, just slightly exagerated). With pictograms: 1) Don't need to know the language 2) *Much* faster to see/interpret 3) Much less distracting.
While not binary compatible, the 8086 was a 16-bit improvement of the 8-bit 8080, which was compatible with the 8008, which AFAIK wasn't too far from the 4-bit 4040 and the 4004... and that's why the space shuttle's boosters are sized according to a horse's rear end and a 64-bit quad core CPU architecture that is influenced by the first 4-bit microcontroller.
Who would have guessed how right they would prove to be?
Who would have guessed chips produced 35 years later, would still inherit the brain-damaged ISA of the 4004. (OK, so the ISA probably didn't look too bad when it was for the 4004)
Not going to work. An independent Kurdistan means the Turkish kurds would want to join them, which would create conflicts with Turkey. The sunnis wouldn't want to be by themselves because they wouldn't have access to the sea, nor (most importantly) and oil. The shias would probably become even closer to (if not merge with) Iran, which of course the US doesn't want. Of course, it doesn't solve the problem about places where there are both shias and sunnis either. I'm afraid the invasion has opened Pandora's box and there isn't much that can be done except maybe damage control (and even then I don't see how).
No. Bayesian filtering has failed, just like every other filtering method before it. Modifying it will not work. Adding OCR for image text will not work. Creating a new filtering mechanism will not work. The spamming will continue, more and more of it will get in.
I don't think it has failed. Spammers are now forced to send their messages in images to evade the spam filters. If you manage to filter the images decently, they won't be able to move to another medium. Well, they could, but then the first thing I'm doing is filtering out all attached movies and the like. Spam is only really effective if it can be displayed by your mail reader.
Unfortunately, global warming is a problem who's impact is even less tangible to Americans than problems like future social security shortfalls. As such, I doubt the government will support action until we're in the midst of cataclysmic environmental impact at a nationwide level.
You're optimistic. I say they'll just blame it on terrorism and the Axis of Evil(R).
What are they (legally at least) able to do if I refuse?
In the US? Probably confiscate your laptop, bang you on the head with it and send you off to Guantanamo for sleep deprivation and beatings. But anything else would be considered abusive and thus forbidden by law.

Cost of the LCD screens. I'm not joking.
Only to realise that the extremely high frequency is ionizing my head...
Actually, I wouldn't worry about ionizing radiation as those only start at frequencies above visible light.

Quite a simple task compared to inventing things which do not exist.
And the reason it's not being done despite being so easy is that?..

Thanks. That's the term I was looking for.
Shhhhhhhhh. You're not supposed to say that 'til the wall is built.
Where did you get the idea I meant food. There's more to sustainability than food you know.

It doesn't solve the problem here. When you want people to be able to contact you, you want to post an email address that will not go away.

Rockgod writes with a progress report on the open sourcing of the city of Munich's administration.
Cool, I always wanted to change the city of Munich's administration. Does the mayor come with full source code?
Actually, my Dell came with FreeDOS (and a free upgrade to Linux of course).
