Sqrt(2) is the silver mean for all the reasons outlined in the article.
But note that the diagonal of an A* page is sqrt(5) in proportion to the base, and phi is (sqrt(5) +/- 1)/2, so you can use silver-mean paper for nice modular origami with golden-ratio-related shapes such as the dodecahedron and icosahedron.
I use xwrits too. But it isn't necessary to get a splinting device like "smart gloves". Handeze gloves have been around for years (see google) and can be found at many chain pharmacies in the ace bandage section. When combined with frequent breaks and stretching, it holds the RSI at bay.
I help support a code that was started in 1962 and has been updated regularly ever since. It isn't pretty, but it is probably no more difficult to read than 40 year old C++ code (can you imagine? Shudder!).
It (both the code and the language) works on most major platforms.
It (both this code and the language) helped design your car, airplane, even your washing machine.
Even if you yourself don't know or never use Fortran (the lower case was adopted shortly after the F77 standard was finalized, so it's older than most responders here), you or your compiler probably use fortran libraries.
The new standard makes C-interoperability much easier. So it is likely that any major scientific work you do will continue to use Fortran libraries for many years into the future.
OO is in there because users asked for it.
Why to use Fortran rather than C/C++/Java: if you ever needed a fast multidimensional array, don't bother trying to implement your own in those languages. I know several C++ experts who tried developing their own matrix/tensor packages and gave up -- the compilers were too slow and it was too hard to program.
Fortran cares about precision. Fortran cares about arrays. It handles type conversions automatically. Lots and lots of intrinsics are generic over your standard data types, and automatically handle arrays of up-to-7 dimensions. For scientific programming, these and other capabilities allow you to Just Do It.
You can't really argue with the CS types who hang out on/. They've taken classes from biased CS professors who checked out of Fortran in the late 70's, before F77 was even standardized and the compilers got fast. It is classic sophistry -- rather than look seriously at the reasons why a methodology might be of true value to many people, they reduce it to an absurd absolute and poke fun at it.
Besides, how many CS people actually know how to invert a matrix? (Hint -- you don't compute the inverse).
Thanks for the elucidation! Just a couple of comments: 1) Morale is excellent. 2) First multiprocessor (2P) machine was placed at SDSC in April of 1998, not last year. Last July was when the 8 processor machine was accepted. The 4P had already been there for 6 months.
Wrong. Don't believe everything you read in trade journals. The deal does include the T3E line as well as the installed base. There may be restrictions on further development, though, I'm not privy to such info. See http://www.tera.com/news/acquisition.html for more info.
Hi Durinia, welcome to Tera^H^H^H^HCray Inc.;-) What would you have done? I think the idea was to carve a distinct new identity and maybe imply that we would be doing development as well as research. We're pretty proud of our own research too;-). Welcome to the team!

Bzzt, try again.

Better yet, program in fortran 77 and the screw-up would never happen:

Obviously nobody really reads the spec.
