Replacing Dropbox Pro with Amazon Glacier, and other services

Recently I've started auditing my tech spending to save some money.  One of the things I decided to drop was my subscription to Dropbox Pro, costing me $99/yr for 100 GB.  (really 140, because they double your free-space with a pro account). Here's what I did. Photos: Amazon S3 Glacier Backup A big chunk of my data in dropbox was photos:...Read More

Trip Report: South Africa (Week 3)

Sorry for the delayed post, but I was just realizing that I would be remiss if I didn't post one of the most memorable experiences of our trip: our Safari. Unfortunately, it's hard to describe just how incredible it was to see all the animals on the savana, and after our camera broke shark-diving, my photos are only from my...Read More

Reading/Writing to CSV in Matlab

When doing data analysis, many times your input will come in a .csv file, and you'll also want output in a .csv file.  Unfortunately, matlab's built-in csvread/csvwrite functions are exceptionally frustrating to use for anything than pure numeric input/output.  Luckily, writing your own code to read /csv files (especially with some knowledge of your desired input/output) is pretty easy.

Project (In Progress): The $100 Quadcopter

I've always wanted to build a quadcopter, and I've got some free time so over the next couple months I'm going to try to build one from scratch.  Sure, there are a lot of tutorials out there on how to build them, but many come with pre-packaged controls and are basically just buying the right parts and assembling them. [caption...Read More
