Why we (still) need Fortran, and why this won't change
I saw a link to an article from /. on Wodehouse’s ideas in writing prose used for refactoring code. For those not in the know, code refactoring is the process of rewriting a code to be simpler, or more efficient, more expressive of the needs. What has this to do with Fortran, and in the bigger picture, HPC? Everything.
Fortran has not been in vogue in CS departments in this century, nor for the latter portion of the past century.

Dear spam-meisters of the world
I am a (semi)poly-glot. Fluent (or barely so) in 2 languages. Can read characters of a third. If you push me hard (or give me time), I can even create my own mappings for a fourth (I did this with German and Cryllic/Russian when I visited Vienna and saw a war memorial).
But, and this is the important thing, I don’t know any of the rather large variety of languages you are sending spam to me in.

Wow ...
some time in the last few days we hit 100k views. Well, this is a little misleading, as I installed that plugin about halfway through the life of this blog, and from what I have seen of the logs, the plugin counter is missing ~40% of the views (usually one page referrals). It also ignores the rss feeds. As it turns out, this is important. What is interesting is looking on number of subscribers on google reader and others.

Sherlock Holmes moment
Read this at /. I guess it is not surprising that people would attempt to influence market forces to adjust the price they pay for labor. Increase the talent pool, and competition grows, lowering the price. Cool idea. [please note that this is dripping with sarcasm … I am an avowed capitalist and do not believe that market manipulation is a good thing … the invisible hand as it were, has a tendency to respond to market forces] We have seen this before though, in other labor markets.
