Glitch Undercuts the Dow

The Dow fell over 400 points today. And some IT guy's ass is fired. From Stocks Have Worst Day Since 9/11 Attacks:

The Dow's decline accelerated at a faster than normal pace during the afternoon after a computer glitch kept some trades from being immediately reflected in the index of 30 blue chip stocks. Dow Jones & Co., the media company which manages the flagship index, said the problem occurred after it was discovered computers were not properly calculating trades, prompting a switch to a backup computer.

The result was a massive plunge in the average in the seconds it took Dow Jones to switch to its secondary computers.

SOA Facts

I came across this hilarious list of way more than ten SOA Facts, including

SOA is an anagram for OSA, which means female bear in spanish. It is a well-known fact in the spanish-speaking world that female bears are able to model business processes and optimize reusable IT assets better than any other hibernating animal

SOA actually stands for SOA Oriented Architecture

SOA is also a yoga posture that consists of performing all other yoga postures simultaneously

Submit your own fact. (This site really really needs a feed).

Forms Language Use Case

Tim Bray on the Atompub list:

If I fetch a service doc with a collection with no <app:categories>, does that mean the server is suggesting that I can post any category I want, or that I can't post any category at all?

This question would a non-issue if APP used a forms language. A form for submitting an entry would have a) an enumerated list of choices, b) a free form text field, or c) no field at all to submit the category. No ambuiguity.

Web 0.9

Sure took a long time to pay the car note this evening. I wish the developers had read Mark's caching tutorial (or rather that their J2EE framework developers had). Below are headers representative of about a hundred .gif, .css, and .js resources used on the page:
