Re: Can I just say that Pi day is..

355/113 is better yet, and manageable with 16bit integer arithmetic.

Units, please!

"1,125kg per square centimetre"

If you're going to insist on using non-register units, then please use ISO units of Pascals. At least you'll get a really big number! (I personally dislike the Pascal as a unit, as a Newton isn't much force, and a metre squared is a relatively large area, so you rapidly start having to use MegaPascals by the time you have significant pressures).

So what would the El Reg unit of pressure be, as there doesn't seem to be one in the list?

Quite the opposite

That's exactly what you don't want to do.

Herman Hauser said of the original ARM development: "I gave them the things that Intel and Motorola would never do: No money and no resource"

75 million miles

I rather suspect this is the total length of all the conductors they use, so one mile of ten pair cable will contain 20 miles of wire.

Assuming that it's all 24AWG (817.7 feet to the pound) cable, then it worth about £1bn.

PLoS ONE

In the defence of the PLoS ONE journal, it's not their place to determine how useful a piece of research is. They are there to ensure that the research is done to a decent quality and standard.

Enigma Machine

The Enigma Machine is the cryptography machine used by the Germans for encoding and decoding messages, not the machine used at Bletchley Park to break the cypher. These machines were called Bombes.

A few people might argue about the assertion that ENIAC was the first electronic computer too.

Wrong

A little plate pops up with the message "wrong" on it!

Privacy

"Google’s strict internal privacy policies".

What colour irony?

Counting?

An obvious question, why is the last launch STS133, but STS134 before it?

CCITT CRC

It's a more memory efficient implementation of the CCITT CRC than a 256 element lookup table, but still not the most. A quick search will reveal a five line algorithm that requires no look up and no loop (finding it has been left as an exercise for the reader).

Thumb Up

Akira

I seem to recall that the motorcycle in the Akira comic book was two wheel drive electric.

Mind you, it was also supposed to be 200HP!

comparatively surgical and painless affair...

...unless you are on the receiving end.

@Dani Eder - Electric Roads

It would be rather safer to mount the power lines over head (you'd need two BTW).

Why not reduce rolling resistance and remove the need for the second overhead wire by using steel wheels and a metal surface.

Then simplify the steering problems that may result by placing flanges on the wheels to guide the vehicle and voila you have...

... an electric train. A reliable proven technology that's a damn sight safer than the UK roads.
