Coursera Scraper | Drain the Main Brain
https://drainthemainbrain.wordpress.com/2013/06/22/coursera-scraper
Drain the Main Brain. Skip to primary content. June 22, 2013. A programmer will always aim to take out human repetition. Usually, this means a small investment in time leads to a much larger windfall later when the magic happens with the click of a button (or more likely a command sent to the shell). Sometimes, however, the opposite happens. I actually made this work perfectly a few months ago. I wrote the scraper in Python using Mechanize. I visited their updated site and, thanks to help from a coworker...

Hello 2014! | Drain the Main Brain
https://drainthemainbrain.wordpress.com/2014/01/07/hello-2014
Drain the Main Brain. Skip to primary content. January 7, 2014. A new year with new resolutions! But I’ll be honest, new years resolutions never really did it for me. I kinda set mini-goals throughout the year so I usually don’t need to make drastic changes on January 1st. But, to keep in the spirit of things, I’ll tie in what I’ve been doing since December and call them my resolutions. Picking up some Ruby/RoR using this book. Attempting the Project Euler. Class when it starts in a month. As soon as I m...

Drain the Main Brain. Skip to primary content. December 7, 2013. During the last few weeks at my previous job, I was working on a little project which was originally produced in Excel; so naturally I had to make it… better. I decided it was time to put what I’d been teaching myself to the test and built up this tool. Using Python (SQLAlchemy, Flask), JavaScript (JQuery, D3), and MySQL. 1 Short Term Liquidity. Total Available Line of Credit. Total Credit Lines Drawn. Total Debt/Trailing 12M EBITDA*.

Digit Recognizer | Drain the Main Brain
https://drainthemainbrain.wordpress.com/2013/05/24/digit-recognizer
Drain the Main Brain. Skip to primary content. May 24, 2013. I had actually worked on this interactive digit recognizer a while ago. I planned to make it more comprehensive, but will do that later. The basic premise is to have a canvas for the user to write a number between 0 to 9. Then run an algorithm to guess which digit was written. This is a very common problem and has been tackled thoroughly before (For examples, see post offices. In fact, current methods have over 99% accuracy. Some day I plan to:.

Drain the Main Brain. Skip to primary content. MapReduce Emulator in R. May 30, 2013. Even with a cursory introduction to “Big Data”, you will likely see some mention of MapReduce. It provides the framework to Hadoop which in turn has been used (with some modifications) by many applications. And created a MapReduce emulator in R. In the image above, I have 3 hypothetical tweets with some hashtags. I want to count the number of times each hashtag shows up. In a standard, non-distributed way I can ...Addre...
