You know how hard it was to slashdot a site when there were only five of us? Instead of having 5 million people each load a site once we had to each do it a million times...
There is (was?) a problem with Intel floating point precision. The register internal precision is higher than that specified by the IEEE standard, but when a value is stored it's precision is truncated to meet the standard. -This might not seem like a problem at first glance, but this can happen unintentionally if your code is interrupted by kernel code or HW interrupt. Therefore you can get two slightly different results depending on whether you were interrupted of not. This is unacceptable.
The Fortran libraries, at a significant overhead, keep storing floats into memory to get consistent repeatable results while the C code did not.
Fortran still came up ahead.
If you want to read more about stuff you have to take into account when optimizing matrix operations you can take a look at Ulrich Drepper's long article at lwn.net http://lwn.net/Articles/250967/
If all you need is to crunch numbers, Fortran is a good choice even today. It might not be the best language to introduce someone to computer science, but it is very powerful for anything that has to do with matrix operations.
A few years ago in a physics graduate course we had a simulation project which left the choice of language to the student. We compared performance between implementations in C C++ and Fortran. Fortran was consistently faster by a big margin. It's also very easy to learn.
If the tech is allowed to access and he sees something that is illegal to posses, he then gives a tip to the police, who now have probable cause for a search. Wouldn't the stuff be admissible?
I'm sure the ISS has a working DVD player on it. One difference between a real pirate and a software pirate is that you only hear about software pirates when they fail. So you should probably say that they are the first failed Space Software Pirates. (abbreviate to FFSSP and it may even sound cool)
Although some email clients pretend to have such an option, I have never seen it work. You always get these bogus messages saying that someone is trying to recall the email. Which just makes things worse.
Some tanks have air conditioning. Air conditioning the whole tank does not make sense because once you fire the cannon a few times the whole place is very hot. What they do is have a hose that hooks up to the special overall tankers wear and supplies you with cool air where you need it most. The hose connector is at the center of the suit.
If we are making a list of backup rules, I should also add that if you have not tested to see that you can actually recover from the offline copy, it is not backed up.
It is very common for the first few restore attempts to fail because of a miss-configured backup solution.
One really colossal failure I have witnessed was when several years of offline backups were found to be useless, following a server failure. It appears that the backup agent did not have the right permission to read some of the files. (Yes, it generated errors that should have not been ignored.)
Another really painful one I witnessed was loosing the only 10 year old tape drive, this side of the ocean, that can read the media to a fire, along with the backed up server.
The only way to know that your data is probably safe is after you have seen a successful restore, on another machine.
It was worth it! I would gladly pay a 1B euro fine every decade or two if that's what it takes to keep the monopoly. (I'm not expressing an opinion on whether the allegations are true.)

syntactic sugar is just fine, but what I would really like is syntactic caffeine.
This just shows you, some people will go to great lengths, just to get a first post!

In the good old times, everyone on slashdot read tfa.

The idea is not to punish Iran, it's to punish Nokia Siemens.
The US has an embargo on Iran and Nokia Siemens broke it.

Kinda makes that whole "comparing apples to oranges" argument pretty stupid sounding.
Not to a true fanatic:
Edible
An orange is highly acidic, how can you call that a real fruit?
Fruit
How can you call something who's pealing is not edible a fruit?
Approximately the same size
Approximately? need I say more?
etc. etc.
if you look at the pictures of the google servers, you will see clearly that they have a standard AC power supply.

That said, I do most of my coding in C.

Or am I missing something?
It would be real progress if they could do three blue screens in parallel.

I used to have a network with windows NT 3.51 box and several 95 workstations.
Several times an hour I would see on the NT box a log error saying "An unexpected error has occurred on virtual circuit X."
NT 3.51 came with an online ref book you could use to look up things like that. When looking up the error code the page only said something like:
"If you expected this error ignore it."

What you really need is a TOTAL RECALL option.
