This engine looks to be a lot more complex than the usual two strokes, so it will cost a lot more to manufacture and maintain, a lot more to design and engineer, will have lower yield rates/higher failure rates so it will cost the customer a lot more money. So, as a consumer of engines, do you spend possibly twice as much on the engine because it is 10% more efficient? If the major cost is the engine itself and fuel - as has been the case up until recently - is comparatively cheap which will you buy? As a manufacturer who has to compete with other companies, which design is the best choice for you to focus on? Yes these could have been designed earlier, but the reason they weren't is nothing to do with propping up oil companies profits, it's to do with whether there was any profit to be made in building the engines.
What drove the adoption of fuel injection over carburettors? It wasn't oil companies, it was the pressure of emissions legislation: it's cheaper to produce an engine that meets the requirements with FI. Before that was a factor, carburettors are much cheaper so that's what was used. As fuel becomes more expensive and the quantity of emissions becomes a significant factor it becomes profitable to build more complex and expensive engines because that cost is recouped by the lowered consumption and emissions.
30 years ago we didn't have the electronic control systems, the precise manufacturing and the economic pressures we do now, so suddenly these 'designs we should have thought of years ago' become viable.
I talked to some guys who were doing automotive engineering apprenticeships at Lucas, and they said one of their projects was to design a super efficient carburettor for a motorcycle engine (this was around 1997). Their design was hugely efficient in comparison to the existing product, something like 20-30%, but significantly more complex and hence it was not suitable for production.
It would be great if we actually had all the technology and knowledge that we need to survive for an eternity in peace and harmony with our surroundings, but the likelihood of that being the case, and that it is all being held back by a few greedy corporations seems pretty slim...
Also wrt. the crop based fuels, since this can run on pretty much anything, wouldn't that open up the possibilities for switchgrass, algae based fuels etc. which are not based on food crop sources? Ethanol from corn is a bad idea - and one that is actually promoted by some big evil corporations
I can't speak for the kernel, but the Driver development kit seems to included the same Visual C compiler binaries as Visual Studio, and I would have presumed the kernel (or at least the vast majority of kernel drivers etc.) are built with the DDK.
Yes, but admitting that would likely get you tied to a stake and burned, which is a bit more punitive than 'aw, poor you and your nasty bastard tendencies, here's a lollipop'.
I asked earlier, but does this sort of attack work against the card-reader type solution we have in the UK where you enter a code and amount into the card reader, with your PIN and it responds with an authorisation code. I presume this works using the secret keys in the chip on the card to encrypt a hash of the transaction details, thus the response code is only valid for the amount (you could presumably fake the rest) specified by the user, which would make it a lot harder to clean out someone's account.
What about the card reader solutions in the UK (and elsewhere presumably)? When you go to make a transaction it requires you to put your card in the reader, this talks to the chip on the card. You get get asked to select identify, respond or sign depending on what you are trying to do. Enter a code from the website and your PIN number (into the reader) and you get a response code. I'm no expert but presumably the code you enter is some encrypted hash of the details of the transaction (including the amount), that is then decoded using the key from the card. Thus the generated code is tied to the specific transaction you are trying to achieve so much harder to fake.
I suppose you could do a man in the middle attack whereby the transaction is redirected to a different account, but you wouldn't easily clean someone's account out before they notice that their bills aren't getting paid or something.
Paypal recently implemented a SMS based authentication, so whenever I log in I get a message with a code. Since it is sent to my phone I presume this counts as a 'something you have' factor? To me it seems like a fairly simple and effective way of achieving the security requirements. Saves dishing out tokens (you'd end up with loads of them after a while surely)
By the end of my computer engineering degree I was writing well over a 1000 words a week, and at points closer to 3000, for various courseworks, reports, research assignments etc. We also had to make presentations, produce research posters as well as actually studying and developing our group project. 500 words is _nothing_ and that's from someone who hates having to write essays. In a lot of our written exams you'd write a 500 word essay on each answer easily.
We had guys that spoke pretty bad English, or who I guess had learnt it just to study in the UK, and they managed to get on with it. How is a 500 word essay such a big deal? Hell this comment is 183 words, it took me about 2 minutes to write. Iâ(TM)m pretty sure if I was applying for somewhere like MIT, which is a pretty prestigious institution and to which entry is no doubt competitive, Iâ(TM)d find time to write the next 317. In fact Iâ(TM)d probably write one twice as long and then cut out all the crap.
There was a program on Dave in the UK about world rally car crashes, it might be on youtube somewhere. The amount of damage those cars can take without compromising the safe zone inside for the drivers is phenomenal. You see the cars hit hinkelsteins (the tank traps) at ludicrous speeds and get ripped to shreds. The navigator and driver tend to swear a bit and then get out of the car.
I thought the corner-to-corner strike, like the one in the video, was considered the most lethal. You have all the momentum of both cars, but going through a much more concentrated area. Rear end, head to head, even t-bone impacts surely dissipate the force over a much wider area of the car body. I would guess that driving into a post is also one of the nastier accidents to have. Also, when you're heading down one of those secondary local roads, what is the most likely way for you to hit another car? Probably someone drifting over into your lane because they're asleep or texting or something. Driver side, corner to corner impact, just like the video.
They have that. I thought there was somewhere in Norway (and I thought there was something like a US national seed repository too) that keep seeds for a huge number of food crops, just in case something weird happens.
That's because they don't want any T or A to ruin the lines of their dress. A load of fashion shows look like a bunch of dresses on hangers with heads attached.

It's not just Linux. I get reports from customers saying things like 'the output is corrupted'. What output? When? You want it fixed? Well you'd better tell me what the problem is, otherwise I guess you're just venting or trolling, neither of which requires nor deserves my time and attention.
A great many people here in Blighty (myself included) think that we are slowly developing the same compensation culture as the US. It seems that you are taking our attitude that you can do nothing to help yourself, please leave all dealings with criminals to the police, who will call you back two days later with an incident number and tell you not to expect them to do anything about it. Sharing is fun!
I was really disappointed when I read an interview or something with her somewhere, and then even more disappointed when it went on to say that she gets paid silly amounts of money (10s if not hundreds of thousands if I recall) to turn up to nightclubs, even if only for a few minutes. Maybe it's because I'm not in that 'scene' but who the fuck is it that goes 'oooh, paris hilton went to this club. We could be almost as cool as her if we went as well'. That it's worth paying her that much suggests that she is but the queen of a huge portion of society that is entirely devoid of purpose and intelligence. Sod the telephone sanitizers and hairdressers, it's the airheaded celebrities and their legions of adoring morons that should be shipped off into space. I'd suggest they should be dumped in a volcano but I don't want them becoming a religion...

The big controversy recently was dropping the 10% rate, which meant that the really low earners took a hit, so that the rest of the country could have a couple of extra pounds in their wallet. Definitely one of the more idiotic decisions I've seen made...
The grandparents being exhumed was a reference to the more extreme actions of some animal rights nutters (the ALF possibly) in which they decided that the best way to torture some scientist was to exhume their dead grandparents. I didn't want to create the impression that I was only referring to suicide bombers, since there are many other acts of terrorism performed by people with a hatred for some aspect of humanity.
I replied to a similar post above. I know it was all the way back in the first paragraph, but this very reasoning is my point. It's not for some higher purpose that we should seek to preserve life, and it is delusional to think so. The reason to preserve it, as I said is selfish:
We want to preserve life on the earth for our own self interests: because we depend on it (and because we think it is cute). We want to preserve the environment because we depend on it (and because we think it is pretty).

- Their shareholders have a limited amount of risk they are willing to take with their money.
- All the things you have mentioned are illegal. At the moment making it impossible for independent or amateur mechanics to repair their cars isn't
