Marshall's IT Plan for Janelia Farm
By  Kevin Davies
Oct. 16, 2006 |  Driving north from Washington Dulles Airport towards the Potomac River, it's easy to miss Janelia Farm. The only road sign faces the opposite direction, belatedly guiding lost taxi drivers retracing their route in search of the campus. Outside a makeshift hut in the middle of a construction site, the security guard waves a visitor's taxi down a long, winding dirt road appropriately named Helix Drive. Around a corner, however, the scene changes dramatically.....
The data center is completely fiber and boasts a multi 10-Gb network. "That's a constant question," says Peterson. "Am I going to get the data to my desktop fast? If I can't, then I'm going to start having people buying their own supercomputers and sliding it under their desk. I don't want that - it's not cost effective, and you can't manage it." He adds: "We're going to have very high-resolution graphics, and people are going to see it very fast. Just one set of microscopes will be generating 500 GB data/day. 24x7x365."....
With some 1,200 64-bit Intel Xeon processors in all, cooling was a major concern. Peterson explains: "We ended up going with Dell and Xeons, which are hot, but we did a calculation: given the price we got with them and given the increased power requirements, it still came in price effective. Having said that, we're very interested in the new generation of Intels and obviously AMD." ...
Everything in the data center is designed to be ripped out and replaced if needed. "The idea is to design infrastructure that is cost effective and easy to replace. We try to be open source - everything is Linux-based, low stress. It helps hugely with the maintenance."....
Peterson selected three tiers and 150 TB of spinning disk storage from EMC. "We started small... seriously!" Peterson smiles. Tier 1 is 30 TB of SAN. Tier 2 is 70 TB of NAS. Tier 3 - the archive - consists of more NAS on disk plus tape. Peterson wants to expand tier 3. "We have capability of over 1 PB of tape," says Peterson. "I can grow to multi petabytes without adding another cabinet." He opens one of a long row of EMC cabinets to show rows of vacant racks....

Gaming the Search Engine, in a Political Season
By TOM ZELLER Jr.
Published: November 6, 2006
A GOOGLE bomb — which some Web gurus have suggested is perhaps better called a link bomb, in that it affects most search engines — has typically been thought of as something between a prank and a form of protest. The idea is to select a certain search term or phrase (“borrowed time,” for example), and then try to force a certain Web site (say, the Pentagon’s official Donald H. Rumsfeld profile) to appear at or near the top of a search engine’s results whenever that term is queried.....

Letter ("Programming Pedigrees") responding to "The Semicolon Wars" -- American Scientist

Resurrected one of my favorite letters, which might be good to follow up on. Viz: :
I read with great interest Brian Hayes's recent column "The Semicolon Wars" on the genealogy of computer languages (Computing Science, July-August). I was struck by the first figure that shows how many well-known languages are related to each other in a tree-like structure. Mr. Hayes carefully compared the development of computer languages to that of spoken languages. This is, of course, quite appropriate. However, another illuminating comparison is to the development and evolution of genomes in biology.
The genome has often been compared to an organism's operating system, and in this sense, its underlying genetic coding is the ultimate computer language. The triplet codons in the literal genetic code have not changed much over time. However, the specific features they encode in different genomes have changed dramatically since life first appeared.
One of the nice things about biology, moreover, is that the main mechanisms underlying this evolution can be studied experimentally. It is believed that the genome evolves through a variety of processes duplicating and copying chunks of DNA, and then further variation happens to these copies. One also sees, most often in bacteria, whole genetic elements horizontally transferred from one organism to another.
The parallels to computer languages in the operation of these mechanisms are quite strong: In a specific lineage of languages (such as that for Algol60, C and Java) one sees the duplication and variation of basic control structures for such items as loops and subroutines, and horizontal transfer of new structures (such as the object-oriented constructions from Simula67).

A Letter in response to "Inspired by the Cell, With Mitochondrial

Here's the letter I wrote in response to this article (which was never published):
I read with great interest the recent article in Science Times about the new biomedical research center in China with architecture inspired by the cell. It's a great thing having man-made creations inspired by fundamental molecular and cellular architecture. It's ironic that this hasn't happened to a greater degree. Many of the shapes in scientific structures are particularly interesting. Good examples would be the famous double helix of DNA and lipid bilayer of the cell membrane. Moreover, a key aspect of post-modern architecture is referring to and playing with evocative shapes and forms borrowed from non-architectural contexts. Thus, the irony in why famous pieces of post-modern architecture -- such as the AT&T building in New York, which makes reference to a grandfather clock or a Chippendale highboy -- seem to ignore the fundamental designs of nature.

In the five years since that wrenching Tuesday morning when hijacked aircraft sliced into the World Trade Center and the Pentagon, Americans have been living with a new undercurrent of worry and mistrust. Naturally, there's fear of further attacks. But there's also concern that measures taken to forestall such attacks could erode traditional rights and liberties. In recent months, controversy has erupted over reports that government agencies are monitoring Internet and telephone communications as well as financial transactions. Some of the surveillance programs are said to be sifting through gigantic data sets, scanning for patterns that might reveal criminal intent or activity....
