Cellphone Economics Revisited: One Year In | 26th Apr 2010
Last year I devised a plan to save myself a ton of money by revising my cellphone service. I was paying $576 per year (including taxes) for a mediocre cell plan from AT&T.

Show your support | 21st Dec 2009
Advertising is a huge business on the Internet. Actually, advertising is huge just about everywhere.

Medicine in an electronic age | 28th Aug 2009
The following is the fifth (and probably final) post in a series entitled, “Securing your Email.” I’ve spent the majority of the series talking about logistical things like why secure email is important and how to get started with public-key cryptography.

The following is a prediction of things to come in the next year. I get the feeling that Microsoft is trying to kill the netbook market with Windows 7.

Every year at the SXSW conference in Austin, they invite 20 speakers to answer the same question in 2 minutes each. It’s called 20×2. Two years ago, Glenda Bautista gave her answer to the question, “What If?” Glenda grew up as a New Yorker, and when an opportunity arose for her to take a job [...]
Cellphone Economics | 9th Mar 2009
I’m relatively new to Skype. I’ve known about it for quite some time, but never really used it until recently. Sadie moved into a dorm at school for a few months to save herself the headache of driving 2 hours in the snow every day. Since she would get lonely by herself sometimes, we started [...]
