Interesting, but still on a totally different scale... 1 million people in a week by highways is one thing, but for England we'd be talking 16+ million people (65+ million in 4 weeks) a week by a single railway line (a few thousand per hour at best) - the channel tunnel. The number who could leave England by plane / boat in that time would be tiny in relation to the numbers involved.
I doubt you could evacuate a country like England in a month - the channel tunnel is probably the highest capacity exit, and it's nowhere near enough. Even for a land locked country such as Germany, I kind of doubt the roads / trains could handle that kind of load.
Yep, but while P-code eventually made the compiler easily portable, that doesn't help compiling the first compiler (which I beleieve generated CDC 6600 native code anyway). I'm still guessing the first self-compiling compiler was bootstrapped with help from another language such as ALGOL/W... but I wish Google had more to say on the matter!
I find it hard to believe that Wirth "hand compiled" the firt Pascal compiler - the size of sych an effort would have been unbelieveable.
The history I dug up on Wirth does agree that the first compiler was written in Pascal (after an aborted attempt to do it in FORTRAN!), but I highly suspect that was only the first FULL compiler, and that it was in fact bootstrapped from ALGOL/W which was Wirth's prior creation (and which I actually used at college in the late 70's!).
With an estimated 15-20 Linux users, I think there's also a lot of home & student usage, plus the cost benefit of Linux is causing poorer countries such as Brasil to look at Linux for use within the school system.
You may believe you are god's gift to your boss, but the people you are workign with most likely have degrees (which you obviously don't) as well as years more experience than you do. You may be doign your job OK, but I bet in ten years time you'd be the first to shout how much more useful experience you have than some 20 yr old, and how that experience helps you see things at a higher level and make better decisions.
The tech job market is competetive, and it may well be that although you're doing OK, that your performance falls short enough of what the higher ups know a more experienced person would bring to the job. I'd really adivise you to look for another job, although your other alternative would be to ask where you are coming short of expectations / requirements, and what you can do to improve yourself.
If the codec does something revolutional like not using DCT
Well it's easier to throw out perceptually redundant high frequency information in the frequencey domain, so almost any CODEC is going to start with SOME sort of frequency transform, whether DCT (MPEG, H.26x), DWT (wavelets) or even plain old FFT.
Reality also dictates that one movie frame is related to the previous one (except on MTV), so a keyframe difference mechanism is also pretty much mandatory for good compression.
Advances in video compression are really more in the details (e.g. CU30) than in the overall techniques applied. The only way to get radically better compression is going to be to transmit a model of the scene rather than the pixels themselves.
Are you asking how to make money from it, or how to donate it to the open source community?
How competetive is it? DivX/MPEG-4 even if patent encumbered is now available in an open source version from the ffmpeg project, and there are other open source CODECs available that are competetive to or even better than DivX such as VP3 or the amazing CU30.
If your CODEC can compete with the alternatives then it would probably be instantly adapted by the Ogg Tarkin paroject which is looking to deliver an open source CODEC but so far is really only at the research stage.
If your CODEC csn't compete head-in with the state of the art, then maybe you're better off looking to embed it in an application (e.g. a cross platform ICQ video conference helper) where the utility outweighs anything else.
Consider dividing a 1000 house pizza delivery region by splitting it into a grid of 10x10 regions each containing an average of 10 houses.
N^1000 vs 100 * N^10 looks like a no brainer to me!
Now of course it's not optimal, but with a not too big, not too small grid it's going to be good enough, and if you can assign 10x10 pizza boys to the job they'll probably be done before the lone pizza delivery boy has even submitted the job to distributed.net
I'll give you the O(google) multiple snafu though!
I've discovered a wonderful linear way to calculate optimal routing that I'd like to share, but unfortunately my keyboagu;[f=s af\sdfgsv asdfw352.,.f354asf
Maybe that'd be true if Pizza Hut had a single guy to deliver ALL their pizzas (boy, would that job suck!), but in reality they use parallelism - multiple pizza deliverers that deliver a few pizzas on a simple route.
I pity the poor pizza boy who not only has to deliver pizzas to the entire United States, but maybe also has to wait for an O(google) (but not NP - whoopee!) algorithm to calculate his route before he can even start!
I'd like to see a grizzly vs a polar bear - my money would be on the polar bear. I also can't see a grizzly doing to well against a large salt water croc!
The Romans used to do the same in the colleseum - they not only pitched prisoners against lions, but would also match up various animals. Quite the specacle I guess, albeit rather grizzly (pun accidental).
I wonder if the rapid domination of the planet by humans started with a mutation, just like the way cancers start? & you know how cancers end? With the destruction of their own host, unless they are halted in time.
Well in evolutionary time we've barely even arrived - we've been here for a measly 5 million years or so, vs hundreds of millions for successful species.
I think the jury's still out on whether humans are a viable species or whether we do indeed contain the seeds of our own destruction.
Maybe Kerry Packer should spend his cash on creating a Martian atmosphere and sending a Noah's ark of animal species (minus humans) up there - then they may just have a chance at surviving, and we can stay here and kill ourselves with bioweapons or whatever we're going to do.
The only difference between MPEG-1/2/4 is how motion is encoded. If you capture to I-frame only MPEG-1 (which is what mp1e does), then you have not lost any information, and can recompress when the machine is not recording to save disk space. The CPU usage is VERY low because you're not doing any motion estimation.
Tivo only needs hardware encode because they wanted to keep cost down by using a cheap embedded controller - a 66MHz PPC variant.
The X-Box has a PIII 700MHz which can VERY comfortably handle real-time software compression using mp1e for MPEG-1. If there was a problem with simultaneous encode and decode, then there's always the option of doing a lightweight real-time encode and recompressing to save space in the background.
I don't see why. You bought it - it's yours to play games on, hack or use as a door stop as you see fit. It's not like a piece of software that's really being licensed rather than sold outright.

.. and George Bush has announced that if an asteroid hits Afghanistan, he's giving $25 million to Billy Graham.
I almost wish I had a reason to make something like this myself.
How much of a reason do you need?
How about just for fun - as a hobby!
Nope - she's trying to tell you that the UCSD P-system predated Java by 15-20 years, and achieved the same portability.
Yep, but while P-code eventually made the compiler easily portable, that doesn't help compiling the first compiler (which I beleieve generated CDC 6600 native code anyway).

IMO a single photon doesn't qualify as "Light".
Calling that a LED would be like taking something that emitted single H2O molecules and calling it a tap!
Bah humbug.
Yeah, 640KB is enough memory for anyone.

If I don't have 24x7 access to top quality German porn, then the terrorists have won!
... but Mozilla is avalaible for every platform, so open source saves the day, again.
I don't think it'd take very long for a kid deprived of porn to slide on over to mozilla.org and download a build.

So it looks like hardware hackers only with the appropriate tools and skills.
Only to do the initial work. Presumably you can also flash the ROM in place, which is what Microsoft would do if they need to upgrade/fix it.
All we need is one person to create an X-box game that just flashes in a Linux BIOS and can boot a linux image from CD.
The benefit of disassembling the ROM will be to help figure out the hardware and to therefore be able to replace it with a Linux BIOS.
