Hypothesis testing proves ESP is real
Or maybe it would be more accurate to say that ESP proves frequentist statistics isn’t real. In what has got to be one of the best object lessons in why hypothesis testing (the same statistical method usually used by the medical research industry to produce the Scare of the Week) is prone to generate false […]

Finally, a good Subversion client for Mac OS X
If you don’t have a Mac, or don’t know what SVN is, please accept my apologies for this very directed post. To the one guy remaining, rejoice: For the longest time, there has been no good SVN interface available on the Mac. Windows folks had TortoiseSVN, and Linux folks wouldn’t be caught dead using anything […]

Getting the most data speed out of your cell phone
You may have noticed there have been very few posts here. There’s a reason for that. The first and foremost is that sending my rants in to the void has not been as personally cathartic as I’d hoped. My other goal for the blog, which actually has been somewhat successful, was to simply provide a […]

First impressions of the iPhone 4
I had the honor of being the last person to get an iPhone 4 in Cambridge on launch day, wandering in to the Reserved line at 8:59, stupidly thinking the store closed at 9:30 instead of 9. Am I glad I braved the line and the self-loathing attendant with standing in line to buy a […]

iOS 4 significantly slows down the iPhone 3G
Just a quick post to warm people that the iOS 4.0 upgrade will significantly slow down an iPhone 3G. I don’t know if it’s the slower processor or the lack of RAM, but I very much regret making the upgrade. The only useful features of iOS 4 that are enabled on the 3G are folders […]

Does the world really need MBAs?
A few weeks ago I was sitting in a coffee shop writing my thesis. Next to me were two students from Harvard’s Business School, that esteemed institution responsible for many of the managers who have been doing such a bang up job of running our nation’s financial system. They were going over a case for […]
