Could you have a superheterodyne radio receiver with just three transistors? Seems to me, even for a earphone radio you'd need at least four - oscillator, mixer, IF amp and audio amp.
The combustion will be higher pressure, which will give more NOx - just like TDI diesel engines.
Umm, I work in a R&D centre in India which designs and builds agricultural diesel engines to meet USEPA Off-Road Tier-III emission standards. Combustion pressures have nothing (or very little) to do with NOx. Temperature and abundance of oxygen have everything to do with NOx. Cooling the combustion reduces NOx. Reducing oxygen by recirculating exhaust gases reduces NOx. But of course NOx is not as big a deal for gasoline (we call it petrol) engines as for diesel engines - and the latter are what I'm more familiar with.
No one wants to have a separate tank that we need to remember to fill-up, and the 10% increase provided by water just isn't enough. This is the same story except it's ethanol, not as easy to find as water, and it's 25% better mpg instead of 10%.
Just routinely top-up the ethanol tank whenever you buy gas. It'll just be a few millilitres (from what TFA says) - maybe up to a litre or so. No big deal, no big inconvenience.
Also a cooler combustion is going to reduce NOx - very important with emission regs. tightening.

You'd be surprised. Do you know that in India where I live the "ultimate" proof of identity is a ration card.. you don't know what that is? You're lucky. A ration card is a grubby document issued from a grubby office allowing you to purchase from the public distribution system a certain quantity of wheat, sugar and kerosene (paraffin). If you don't own a ration card, you're out of luck. No passport, no voter identity card, no permission to buld a house no.. whatever.. can be given you by the Government unless you have one.
Well. we're a manufacturing firm running Oracle Apps as our ERP. Oracle doesn't have enough tech support people (imagine, here in India!) and actually encourages us to enter tech support agreements not with themselves but with their top-tier partners, typically IBM and TCS.
From http://www.torrentocracy.com/blog/archives/2005/02/bram_cohen_unde.shtml Bram Cohen gave a technical talk on Bit Torrent at Stanford.
Update: 3/7/2005, The torrent in this entry was just audio only, but Thomas Winningham has gotten permission from both Bram and Stanford ("Stanford holds copyright on the material but returns the copyright immediately to the speaker, that is, Bram. Get him to agree and go ahead.") to post their video as a torrent on Prodigem. Cool! Updated again since that video posted seems to only have the first 10 minutes. Anyway, the audio is below, or just check out my notes.
Bram Cohen gave a technical talk on Bit Torrent yesterday at Stanford. I had planned to make video from it available, but the video I captured somehow got corrupted (boo Panasonic). I salvaged the audio from the video and have released that via a torrent under a creative commons license (with Bram's approval). The audio is a bit low. It's okay, though, as I didn't realize that Stanford would be making it's video available to the general public (though in crummy windows streaming format). Here are some notes:
- Academic setting... so how to benchmark/measure bit torrent - benchmarking is hard because it needs to be like the internet (buy a bad router) - key problem among swarming software is how to get everyone involved to maximize upload, people don't realize
- Single seeder problem - must be careful not to at first trade with people who are likely to disappear
- Bit Torrent extremely non-cooperative - each peer in it for himself - tit for tat - editorial note: isn't this cooperative? Peter Kollock: tit for tat as the optimal cooperative strategy
- How to deal with people behind and not behind NAT
- Centralized tracker is needed to produce randomized graph so as to avoid network segmentation - gossip (peers telling peers about other peers with content) very easily segments the network such that pieces of the content get isolated into islands
- Choking Algorithm - sophistication - people like to pretend it doesn't exit - lots of use of made up magic numbers - eg. how long to wait for reciprication? - motivation opaque - methodology (the traditional approach) is Bram firing up a client and observing behavior - lots of room for study
- TCP does not look like RPC calls (BitTorrent treats TCP like a black box) - don't avoid making a state machine, because no matter what you'll end up with a state machine anyway - why threads are a bad idea
- Magic numbers - makes them up based on what works - pulls them from his "magic ass" - if you need a magic number feel free to ask him for one
- Estimated Time Left Algorithm - never gotten any fan mail on how well it works - lots of effort and thought put into making this work sanely - any time you see a computer telling you time left it is lieing - research needs to be done on better algorithms - would gladly place your better algorithm into bit torrent - problem at end about going down 2 seconds per every 1 second - tradeoff between smoothness now vs. smoothness later
- Current Transfer Rate Algorithm - its a mess - very important for tit-for-tat to work
- Bad idea to be downloading too many torrents at one time (e.g. 5)
- Peers at first never randomly tried new connections - added optimistic unchoke to solve this - if new person recipricates then continue - otherwise move on to the next person - may unchoke 4 or 7 clients depending - it's voodoo - nobody has seriously studied this
- Piece Selection Algorithm - trade off between finishing the piece you are currently downloading vs going after a more valuable piece - priority is currently finishing a piece you started even if many others have it - downloading from the beginning of the content for everyone is a maximally bad strategy
=="This would only be true if each individual torrent maxed out your connection. In many cases it does not, and wouldn't cause much(if any) slowdown on other torrents."==
I'm no expert, just reporting what I've been listening to Bram Cohen saying.
AFAIK streaming won't work because the info. arrives in deliberately random chunks so as to even out which peers are u/l-ing and which is d/l-ing. Everyone gets to contribute within a pretty short time of joining a torrent.
"Really nice because opening up 5 torrents used to mean 5 seperate windows."
Bram Cohen addressing a Stanford CS group earlier this year said this was a specific no-no. You don't get the d/l's any faster because the individual rates slow down so that you get them LATER than when they would have d/l'ed sequentially anyway.
D/l sequentially and you get 100% of one d/l followed by 100% of the next etc.
Of course if the idea is to leave BT to its own devices while the oh-so-busy user does 'real' work then..
No that would be impractical if for example the Visby were hit in mid-Atlantic. Can't drydock it there.
I would guess the overlapping mats of carbon fibre would fail (on ordnance impact) as a small ragged hole - as opposed to a large torn aperture in the case of steel hull construction. And a small hole in carbon fibre would be easier to fix - for example send down divers over the side with Kevlar blankets and self-clinching fasteners - hull construction could even deliberately incorporate a grid on the outside of the hull - of hardpoints with embedded fasteners - specifically designed for this purpose.
Laws are passed by elected bodies in full session.
Ordinances are passed by governments - which are a subset-by-appointment (of an elected body like a Central Government or a State Legislature); and ordinances do not require a full session of the elected body to be held.
In general the average India surgeon operates on many more patients than the US surgeon. It's simple, there are just that many more people in India, and far fewer surgeons. So the level of experience for common procedures is higher in India than in the US. If a medical procedure calls for a cyclotron and a super-computer - the Western countries are where THAT can be done. But a heart bypass - it's done routinely and successfully all the time.
I live in India. My daughter's life has once been saved by the India public (read free) health system. So I'm prejudiced in its favour.
Of course you can get excellent (if expensive) medical / surgical treatment in the US.
And of course some India doctors are venal and money-focussed.
But don't dismiss India doctors and India hospitals as a whole. On the whole they are very very good. And they are about as likely to skip legal consequences (if any) as a US doctor or hospital. Note - the judicial system in India does NOT have jury trials. So no little old ladies get awarded a hundred million when their nose jobs go awry. But there is adequate enforcement of accountability in medical practice.
My company was in the process of buying a few million $$s worth of diesel engine test equipment from an Austrian firm.
Their "tech support" insists that we need one particular brand (obscure, Austrian) of Wintel server in order for their Oracle based software to run. And no, it didn't work on Linux.
I suggested that we use a cheap Compaq or HP server do do the (not too demanding) job.
Back cames a mail from the Austrian expert to the effect of "Ho! Now our customers are going to begin designing OUR systems!!??"
So now I know it was a cultural difference that made him say that. Back then I thought he was a prize a##hole.
"At the same time, if we truly have the will to dump ICANN, and we all do it at once (or at least the most commonly used nameservers do it at once) their power can be totally stripped from them."
== This is a political, not a technical problem.
== A shrewd political maneuver would be to use the transition to IPv6.. a lot of things will change in the process.. to make sure that ICANN does not retain anything like its present monopoly power.
