60 Minutes said most stock trades are made by computers without human involvement designed by math wizards for pennies of profits per trade over billions of trades. Milliseconds become important to beating the competition (other computers) by being faster. Getting close to or in the stock exchange buildings has physical effects. Of course, a bad algorithm…
A friend posted the Internet Explorer users ‘have below-average IQ’ story on Google+. On the one hand, I love the idea of bashing IE users as incapable computer users who ought to get off the Internet. But then my Psychology background screams at this study as generally worthless. The lack of a statistical analysis ought to…
Facebook and Google+ both have ways of categorizing people for targeted sharing. The first way I attempted to handle my Facebook lists was basic categories like Coworkers, Family, Friends, Internet, and Locals. Then I switched jobs. It became a little weird to gripe about the new job to both, so I went down the crazy…

We maintain a wiki page with which DBA will do which maintenance. By convention, the months are the first three characters of the month’s name. In doing updates, I noticed only month marked as misspelled was Sep for September. So Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Oct, Nov, Dec were all okay spellings but Sep was not? Changing it to Sept made it…
We acquired Blackboard Mobile Learn Powerlink version 1.1.9 to solve a problem. Something was done on the Blackboard side before our institution administrators could successfully get to the registration page. This version fixed that issue by doing a registration behind the scenes. Naturally the information it has is wrong, but at least now the institution administrators can…
