I rode my bike from East Acton to Imperial College nearly every day for two years. I didn't have any major accidents. You know why? I'm one of the few cyclists who stops at lights and actually learns how to use the road.
It angered me every day to see other cyclists jumping traffic lights, not having lights at night, riding on the pavement, riding at pedestrians, and edging across the front of stationary traffic rather than changing lanes properly. I saw several cyclists hit by cars, and each and every time it was their own fault it happened.
The times I rode round the rest of London, I saw very few accidents, but again, the ones that did happen - it was the cyclists fault.
I'd count the areas you mention as some of the better for riding, because most vehicles are aware that there are a lot of cyclists about, and will notice you and not cause you problems. Move out further, and your job gets much harder.
Connect up a fax machine - if that blows up, then you can get somewhere as BT need to provide at least a 4800 or 9600 bps (can't remember which) fax connection can be established.
90% of my research is in EE or computer science. And it is a rare occasion when I can't find a paper, even ones from the mid eighties or earlier. One of the many citeseer sites is a great help e.g. this one.
Sometimes papers are submitted to journals, and are hard to find elsewhere. Most of the time, an e-mail to the author will get a response, or it can be found using a search engine.
It's been a long time since I have looked in a paper journal, yet I still know of universities who shun electronic access...
If you'd RTFA, you'd realise that it only works with files that are larger than 5Mb. It's not designed to work with HTML, it's for media files. This problems going to continue until most of slashdot pull their heads out of their arses.

When I was about 14 I got a Omni Jnr robot from a car boot sale for a few quid. It had tank type steering, a bump sensor on the front, flashing lights, and some preprogrammed bits of speech when you touched various bits.
He would autonomously move round, bump into things, say sorry, then reverse and turn, and do the same thing. You could also put him in remote mode and control him with the ultrasonic handheld control.
After a while, he got boring and expensive, eating all the batteries up. So switches went in to turn off the speaker, and to turn off the flashing eyes. I also put in a switch to turn off his bump sensor, but I can't remember why.
Computer control and remote power was what it needed. A huge length of ribbon cable was obtained from a skip, and I fed power down it, as well as soldering the other wires so that they could use the motor controller inside.
The next few weeks were spent hacking away at my C64 with an old broken cartridge and the user port. Eventually, I got reliable control of the robot... now I had real power.
I didn't really know what I was doing, but was pretty proficient at basic, so I wrote an application to map my house. You would time how long he went until he hit something, then back up, turn left, and do the same. From the time, you could infer distance. It would have worked, bar the fact that the speed changed all the time, and the umbilical cable caused loads of drag. Sometimes it gave reasonable results.
Unfortunately he got binned when my dad cleared out my shed.
You really don't understand current. A device will draw a given current for a given supply voltage. You cannot give it more current than it wants without increasing the supply voltage. They are linked, one cannot change without the other. A resistor will only serve to drop voltage from 12V, and this voltage drop is dependant on the amount of current the device is drawing - so it just ends up as a useless heater.
It seems as if, reading the report, that nearly all of these accidents resulted from someone putting the nozzle into the vehicle, then locking it on, leaving, coming back, and a static discharge igniting the vapours near the filler cap.
This is reasonable - you quite often feel small static shocks. Especially in dry hot weather, perhaps explaining a high incidence of acccidents in Texas and Nebraska, and a lot less in humid coastal ares.
And when you are filling up, you often see clouds of vapour almost pouring out of the filler. These would be very easy to ignite.
Here in the UK you can't put a pump on automatic fill. You need to hold the trigger whilst all the time. The handle is grounded, so that as soon as you touch it, the static goes, and as long as you keep on holding it, there won't be a problem, as there will be no sparks.
I'm currently working on modular multiprocessor systems implemented on FPGAs, so this field is something I know something about.
Altera produce an FPGA with one or more built in ARM processors. This sounds very similar to the Scratch system, but the ARM processors are limited in connection into the fabric of the FPGA by the not particularly fast bus used with the processor. Scratch appear to have made the data transfer rate between the two parts of utmost importance, which is essential in high throughput applications like this.
Altera have also developed a softcore processor, that is one implemented entirely on an FPGA. It is highly configurable - instructions can be added, cache and memory behavior altered, buses adapted, etc. Coupled with things such as the DSP blocks (trees of multiply accumulates), a 50Mhz processor can process data in a specific task at the same rate as a general purpose processor running at 10 times the speed.
The work I'm doing is investigating the use of many of these processors on one fpga. Levels of optimisation that cannot be done with conventional multiprocessor systems will be possible. Changing the memory system to deal with specific algoriths, or bus widths between certain processors will allow much better performance.
Scratch also seems to be making a difference by claiming to have easy to use and working development tools, which is one thing that Altera cannot really claim to have done.
What happens if a turbine blade breaks in an airliner? What happens if someone pours a toxin into a city water reservoir? Shit happens when you use complex technology, you reduce the chance of it happening to a reasonable level. What kind of idiot would use mirrors to make the car look smaller?
Erm, surely you have to put the power in for these half dozen iMacs? You wouldn't get away with half a dozen trailing extension leads in a school, it would have to be done properly. So if you need to put the power in (which is quite a job, and has to conform to regs), then it isn't much more effort to put network cables in. I'd also say that the money you saved using network cards costing 2/3 instead of 20/25 makes it worth it.
How does that solve the problem of having to maker cds or mds when you want to listen to music? You might have been trying to be funny but you've come across as stupid.
The name differences with this stuff is really weird. In the UK, it's often marketted as "duck tape" for the really sticky woven tape that is generally silver.
But, it's always been my understanding that it goes like this:
Duct tape is thin metal foil with a seriously sticky adhesive. You use it to seal up ducts in HVAC systems. No fabric, no weaving, and a permanent seal.
Gaffa tape (same as duck tape etc.) which is used for everything.
Book tape, like gaffa, only with a different adhesive, used to repair spines of books.
Ha! The C64 disk drive had it's own processor which you could use to run programs as long as you could deal with the painfully slow serial link. Beat that.
They've asked us to stop eating in Pizza Hut with the all you can eat pizza, pasta and salad. It's only 5.95 and if you arrive early and stay late, you can easily get 15-20 slices in, as well as loads of salad.
I've carried my Gerber for 3 years now, and use it every day, and it is a lot better than a Leatherman:
- tools are accesible with the pliers retracted.
- pliers are sprung.
- wire cutters are easily replaceable by undoing and allen bolt and spinning the cutter.
- replaceable hacksaw blade holder.
- nice rounded edges and grippy rubber means the pliers can be used for really hardcore stuff.
- scissors actually cut stuff.
- canvas pouch with velcro works a lot better than the cheap leather and popper Leatherman version.
- it has a Gerber knife on it (which are amazing blades, living up to the "legendary" slogan).
- much easier to use with wet and cold hands.
etc.
People go on about the fact Leatherman has a lifetime guarantee and Gerber only a 25 year... if you use your multitool enough, then you should easily have lost it or worn it out by that time anyway.

I wanted to make it more elaborate with links and references, but I knew that someone else would have been working at it... :)

How did this get to insightful? Humour - not always supported in the moderator's brain.

Nice, but freecache state that they do not cache files smaller than 5MB. These are just using the original server.
That's a ridiculous way of saying it. It makes no sense. You could say the following:
1 byte/s = 8 bits/s
which infers that you are saying how many of one equals the other. Putting in a multiplication sign infers otherwise:
bytes/s * 8 = bits/s
This suggests the correct conversion betweeen the units, as in, each byte had 8 bits in it. This makes complete sense.
As you wrote:
bytes/sec = bits/sec * 8
This is just wrong, and nothing else. You suggest that there are 8 times as many bytes as bits, there is NO OTHER WAY of interpreting this.

Use a normal woodscrew then use the pliers on your multitool. Works really well.
I've carried my Gerber for 3 years now, and use it every day, and it is a lot better than a Leatherman: - tools are accesible with the pliers retracted. - pliers are sprung. - wire cutters are easily replaceable by undoing and allen bolt and spinning the cutter. - replaceable hacksaw blade holder. - nice rounded edges and grippy rubber means the pliers can be used for really hardcore stuff. - scissors actually cut stuff. - canvas pouch with velcro works a lot better than the cheap leather and popper Leatherman version. - it has a Gerber knife on it (which are amazing blades, living up to the "legendary" slogan). - much easier to use with wet and cold hands. etc. People go on about the fact Leatherman has a lifetime guarantee and Gerber only a 25 year... if you use your multitool enough, then you should easily have lost it or worn it out by that time anyway.
Conventional GPS can't be accurate to a few centimetres. Even using WAAS it's still metres.
