PSA diesels do appear in Volvos, but not the ones that can be run on biodiesel. It's only the current S40 and V50 models that get PSA engines, and these engines are only recommended for a 95% mineral 5% biodiesel mix. The previous generation of S40 had a Renault diesel engine in it.
Renault makes its own diesel engines, its only Citroen and Peugeot who are part of the PSA group and get their engines. The engines you refer to as having the "Bosch type pump" are most probably the XUD engines (these engines were never used in a Volvo or a Renault to my knowledge). The Bosch injection pump uses seals which are resistant to vegetable oil, where as the Lucas (Roto Diesel) pump does not. Both types of pump can, however be used with biodiesel.
The government commisioned Ricardo to do a study into the effects on emmisions of using vegetable oil in diesel engines, I've read the report and the conclusions were that it INCREASED the emissions, that is nitrous oxides, carbon monoxide and hydrocarbon particulates.
It is illegal to use vegetable oil in a road vehicle unless you pay the duty on it PRIOR to using it (47.1p per litre). Also, vegetable oil does not qualify for the reduced rate of duty that biodiesel qualifies for. Vegetable oil is classified as "diesel fuel substitute" not biodiesel.
The sound card market started to shrink and everybody felt the pinch.
Creative was in the position of being the big maker of sound cards when PCs didn't come with sound, maybe Adlib were the first but Creative developed the market with the original SB, the SB Pro then the SB16. Then competition arrived and PCs started to come with on board sound, now motherboard chipsets have the sound hardware built in, every motherboard comes with decent audio. Creative is in a difficult position as was every other sound card maker, who is going to pay for a sound card when their PC sounds OK? The majority of people (i.e. non-techs) won't know the difference so the market is pretty small, i.e. the motherboard and chipset makers (AC97 and the like) killed off the various sound card companies and no doubt will kill Creative given time.
My family runs a family business that I'm never going to involve myself in if I can avoid it. I can do without getting involved in the sibling rivalry, score settling and grudges that go on there.
I've been refilling my Epson Stylus 660 for years now without problems. I've been through a few refill kits.
I did get to the stage where the cartridge was full of dry ink and would keep drying up soon after a refill (i.e. they became non-refillable) but a new cartridge sorted that out and the refilling continued.
These days I can get generic cartridges cheaper than the refill kits so thats the way I've been going.
Just because something costs more doesn't mean it is better.
If you can save money in one area, the money doesn't just disappear, you can spend it somewhere else instead, offer an overall system of education that is better.
When I was at school, my school had BBC Micros and BBC Masters, they were obsolete at the time, I had a 386 at home and the Pentium had been launched. These days I work as a Software Developer, so lack of exposure to Wintel PCs at school did me no harm whatsoever.
How about taking the hyperthreading paradigm further. Have a single (big) set of execution units and let it support 8 or 16 way hyperthreading. With enough execution units shared around you would get the advantage of 1 thread having loads of execution units to be excuted on (1 fast thread) or many threads could share the units. When threads stall, their execution units would be dynamically so no CPU or execution cycles get wasted.
There isn't really goint to be a big difference in latency between a 166DDR and a 333SDR bus since the 166/333Mhz refers to the burst transfer rate. I should probably add that comparing the two has a distinct air of comparing apples with oranges...
Think RAS/CAS delays etc...
What a DDR system does is reduces the energy that the bus associated with it needs to drive the clock (since half as many clock changes means half as many capacititive charges / discharges) thus meaning the bus can run faster for a given temperature / power rating.

If the world is in as bad a state as the picture you are trying to paint, why not end it all now. If you bit down on the cyandide capsule now, you'd be dead before you read to the end of this comment. Then we'd all be able to discuss laser eye surgery in peace.

Is there a good C++ equivilent to _the_ K&R C book??
The University of Manchester (UK) has done work in producing several different implementations of a fully asynchronous CPU. It supports the ARM instruction set too...
City Centre London, especially Oxford Road is notorius for pickpockets, the Metropolitan Police have been using cameras to combat the pickpockets to great effect for some time. The Police can get hard evidence that will lead to the prosecution of individuals for their crimes.
iSee is a tool that can be used to aid criminals who potentially could be identified by security camera pictures.
I can't see that it has any other use, unless you are actually doing something wrong, do you have anything to fear from the cameras?

What does an instruction set have to support to be 64 bit?
Is it the instruction length? Is it the register length? How about the bus width?
64 bit general purpose registers to me signify that a processor is 64 bit and that is what AMD64 has.
What can be done in Java that can't in C++?
The sole advantage of Java was "write once run anywhere" and with platform independant C++ you can get close to that anyway by recompiling.
