Intelligent Design hypocrites, time to roll in your own graves! Uh, assuming you already died of course. Otherwise, prepare the bucket for throwing up because your main argument for ID is hereby proven wrong:

Or in higher quality:

Really? That type of algorithm you can just run in the background (for 3 weeks!). And eventually (depending on how long you are willing to let it go on) you will get a (near) optimum solution.

Of course, it's a random algoritm (that is, random as in output, not an algorithm for generating random numbers), so it may not produce anything for a long time.

I mean coming up with the idea to do this, writing the program, running it and putting the results on youtube!

The idea is easy, especially if you are hammered by people that ID is "correct", especially with such a lame example as breaking a clock and then saying that it can't "evolve" back.

After that it's coming up with some form of "DNA" which represents a clock (or interconnecting parts and info about the parts), and then breeding is easy (both crossover and mutation). Basic Genetic Algorithms.

A man who lost his left hand in an accident three years ago has been fitted with the world?s most sophisticated prosthetic limb.

Evan Reynolds, 19, took only minutes to learn how to manipulate the i-LIMB, which is operated by tiny sensors resting against his arm muscles.

With his new hand he can now pick up a paper cup filled with water, peel a carrot or walk down the street eating crisps, all activities he could only dream about before.

It doesn't matter really (I don't care either way, and nor should you).

The being factual can be debated, but this is a moderator thing, so move along.

Useful fact of the day: You can make ships out of concrete. As is (well... was) the one above.

That's not really as strange as Project Habakkuk in WWII, which concerned itself with the possibility of making an aircraft carrier out of Pykrete.

(Pykrete = 14% sawdust + 86% ice)

Computers are going to fail at 03:14:08 GMT on the 19th January 2038.

Computers measure time in seconds since the Unix Epoch, which is midnight on 1st Jan 1970. We're at about 1.2 million now. Computers store this time as a 32 bit signed integer. That basically means 31 bits for the actual number, and 1 (the first) to say whether its positive or negative. When we reach 03:14:07 GMT, the time stored will be 0111 1111 1111 1111 1111 1111 1111 1111. Exactly 1 second later, it will be 1000 0000 0000 0000 0000 0000 0000 0000, which is 20:45:52 GMT on 13th December 1901.

The main and more immediate implication of this, is that no task can be scheduled to end after 03:14:07 GMT, as the end time, as far as the computer can tell, is over 100 years ago! Most computers probably have safeguards to stop you scheduling tasks to finish later than that, but it's still a hell of a problem!

The problem is that the 32 bit signed integer is so embedded in modern computers, it will be next to impossible to change before the aformentioned date.

Sounds like the Y2K bug, all over again. I'm sure we'll figure out a solution within 30 years

You know, you might think that eating bugs is disgusting etc and you will never do it, but if you think about it...

...prawns are bugs of the sea.

I mean, the exoskeleton (fishes don't have that. Beetles on the other hand...) and number of legs should have provided a clue, but let's examine this a little further.
Animals are biologically classified in Kingdom, Phylum, Subphylum, Class, Order yadda yadda.

Prawns, if you go a bit high, ultimately belong to the Subphylum "Crustacean", where all things prawn & shrimp belong (but not for example, mussels). Land based things that belong to the exact same subphylum are things like this:

(Ewww)

Finally, if you go one level higher, from subphylum to phylum. All these belong to "Arthropoda". And that's where pretty much all insects and spiders belong.

So the truth is that we do eat bugs in the west, and like them very much as well. Every time you see those nice prawn packets in the super market, you are being sold something like peeled beetles.

The difference with the Y2K bug was that that wasn't to do with the fundemental operation of the computer. That was only about it's inability to go from 99 to 00 then carry on. There were only 8 documented cases of problems with the Y2K bug, and 2 of them were websites showing the date as "1/1/19100".

Most people and businesses still use 32-bit. And I didn't know if 64-bit computers stored time_t as a 64 bit integer.

USS Frontier · « **Reply #939 on:** February 05, 2009, 09:53:47 AM »

The most easy solution for fixing this int-32 problem is changing it to a int-64bit.

Doing that will make the "end date" be... well... lets just say that humanity shouldn't exist by then.
