I extracted some of the useful code and nifty examples from the background of my Thesis as a python library for your enjoyment. PCA or Principal Component Analysis is a pretty common data analysis technique, incremental PCA lets you perform the same type of analysis but uses the input data one sample at a time rather than all at once.
The code fully conforms to the scikit-learn api and you should be able to easily use it anywhere you are currently using one of the sklearn.decomposition classes. In fact this library is sort of on the waiting list for sklearn.
This weekend I championed my way through installing SteamOS (the Debian distro by Valve that will be the installed on the upcoming Steam boxes). I had to do some pretty crazy stuff to get it working including dropping out of the automated install to manually inject grub-pc and then compiling the drivers for my wireless card. All in all it was a triumph!
and then finally:
This was an early beta release but they made some weird choices - like handicapping the basic Debian installer by fully automating it and only supporting efi. I was actually a bit disappointed when I finally finished because the end result is not really different from simply installing Ubuntu and setting Steam big picture mode to auto start, I am not sure what exactly I was expecting though. SteamOS is much more for OEMs than the DIY crowd at the moment but I can see that Valve is super invested in Linux at this point with a ton of additions to their own repositories. Good things are going to come of this I can feel it!
* Edit *
Almost all the hacking I had to do has been wrapped in Ye Olde SteamOSe

Wow Valve released an updated version of the beta addressing a lot of the problems Ye Olde SteamOSe addressed and they allegedly collaborated to get this done! This is why Valve is going to win the next generation - working with the community. Full story here
Now that Grad School is over I’m moving on to the next exciting chapter of my career - I’m joining a great company called Shopify in the fall and I am going to be working as a Web Developer! I’m quite excited, in fact so excited I took a course from Udacity to get up to speed on some Web Dev basics.
CS 253 Web Development - Building a Blog with Steve Huffman (for those who don’t know this is the guy who started Reddit so he might know a thing or two about building websites) was a really great course and I would definitely recommend it to anyone who wants to learn a thing or two about the web. I also really liked Steve’s teaching style - while he did a great job explaining things simply he also wasn’t afraid to show how he really works i.e. in the terminal and using Linux/Unix commands etc. The course could have easily hidden all of this away but I think it was important to show - using windows and gui’s just isn’t how people work in this industry so why should the course be taught like so? Good job Steve for keeping it real!
Taking the class was really worthwhile as it helped tie together a bunch of knowledge I had accumulated randomly over the years and it helped make some sense of some of the Django hacking I did once upon a time(I say hacking because I got stuff to work but didn’t totally understand everything).
Here is my hard-earned certificate! I completed the course with High Distinction meaning I did all the homework, the final and the bonus question!
