Graduation (Yester)Day

Last night I received a neat little email from the University of North Carolina at Greensboro. I’ll leave out the verbose output from legal and finance and get to the fun bits that in short read:

Dear Harry

On behalf of the University Registrar’s Office, it is my pleasure to inform you that we have completed the final processing of your academic record.

Congratulations, all degree requirements have been met as of the posted graduation date, December 10th, 2015.

What a thrill it is to know that I have finally completed that damned degree. It was about a year ago that I decided to not return to school in January for the lone remaining class I required, Biology 101 (why is it always a gen. ed. class?). Instead I rode off to the great, mountainous North that is Charlottesville, Virginia.

Living in what will possibly be my favorite apartment ever, I worked as a web application developer for a small non-profit that I had previously interned with — CoS (the Center for Open Science). To them and in particular Dr. Jeffrey Spies and Dr. Joshua Carp I will be forever grateful. The slightly less than a year that I spent in that cozy, gorgeous city was one of great professional and personal development. But all states in life, aside from death I suppose, are transitionary and in October I moved back down to the warm and humid North Carolina to what has been one of my favorite cities of all time — Raleigh.

Too me Raleigh is bikes, beer, coding, music, and friends. More than that, Raleigh is the perfect blending of them in an active city that is neither too large nor too small. It is, at least for now, a good base of operations and one which I want to leave better off than I found it. I don’t know how long I’ll be here. I don’t know how long I’ll be at Red hat. But, I do know that I’m happy to have completed my undergraduate degree, be actively contributing to the open source community professionally,  and living in a city that feels like home.

I suppose I should change the blog description now.

SciPy 2013: Day One

Registration:

This year I am fortunate enough to be able to attend SciPy. SciPy is a Python conference focused on scientific programming. A big shout out to the Center for Open Science for making this trip a possibility. This will be the first of a (hopefully) daily blog series in which I will briefly cover how my day went and any lasting impressions it left me with.

The conference organizers made checking in  quick and painless. We were served a breakfast buffet that was surprisingly good. Of paticular interest to me were the scrambed egg mini-bagels and lemon poppyseed bread slices — yum. Breakfast as followed by a series of tutorials which registrants chose in advance.

Tutorial One: Guide to Symbolic computing with SymPy — Ondřej Certik, Mateusz Paprocki, Aaron Meurer

The SymPy tutorial was … interesting. We simulataneously listened to the lecturer discuss and demonstrate common SymPy functions while completing examples in various IPython notebooks that they provided us with. It was fast paced, too fast for me anyway, and we had to skip over a lot of material.

The tutorial docs recommended experience with IPython and ‘basic mathematics.’ However, I was quite surprised how far my definition of basic mathematics was from theirs. Unfortunately, this left me struggling to keep up with the tutorial even from early on. After a mid-session break, we briefly covered Calculus functionality before being introduced to some real world applications. This is where I became utterly lost.

SymPy’s original lead developer showed us several examples of his use of SymPy while preparing his dissertation in Chemical Physics. These included Poisson Equations, Fast Fourier Transform(s) (FFTs), and Variation with Lagrange multipliers. Don’t know what some (any) of those are? It’s okay, neither do I. On a side note, they did show an interesting ‘hack’ using javascript injectin in an iPython notebook which allowed them to manipulate 3D figures.

While the tutorial itself felt a bit unpolished, the instructors knew there stuff. All in all SymPy seems like a really interesting tool which I plan to use. When combined with IPython notebooks I believe it could create very powerful, long lasting notes for a variety of math intensive classes. I’ll be testing this out next semester in Physics.

Tutorial Two: IPython in depth — Fernando Perez, Brian Granger

Anyone who has listened to either Fernando or Brian could have told you that his tutorial was going to be good. It was. They provided a solid tutorial environment with IPython notebooks that kept me feeling like I was actively working with them throughout the entire tutorial. Whenever anyone had a question they knew how to answer them quickly and concisely.

A few things I found of paticular interest:

  1. IPython Notebook: If haven’t heard of this, click the link and check out. I’m not kidding. This is a versatile web tool that is incredibly powerful. For some cool examples of what people have done with notebook (including writing a book!) click here.
  2. Awesome help functionality: With IPython’s built in help functionality  [ ?, ??,  %quickref, and %magic ] you can quickly get a syntax highlighted help description, the source for a module, or even access a nifty quick reference guide mostly eliminating the need  to pop out of a notebook or console and visit online docs.
  3. Kickass debugger: IPython’s shell is amazing. But, I’ve found myself using PyCharm for more advanced bit of code while debugging. After learning about IPython’s magic %debug and %run -d theprogram.py that may have changed. They provide you with very powerful and easy to use debugging abilities I wasn’t even aware existed.

Day one down. Time for sleep.

-H.
