A good commit message looks like this:

Header line: explaining the commit in one line

Body of commit message is a few lines of text, explaining things
in more detail, possibly giving some background about the issue
being fixed, etc etc.

The body of the commit message can be several paragraphs, and
please do proper word-wrap and keep columns shorter than about

7 Tips for Successful Self Learning - by Bradford Cross

No matter what, you're going to have to learn most everything on your own anyway. Self-learning is hard. Regardless of where, when or how you learn - being a good self-learner will maximize your potential.

In this post, Hamilton Ulmer (an almost-done Stanford stats masters student) and I, will explore seven ways to become a great self-learner.

The longest path is the shortest and the shortest path is the longest

The range sliders at the top change the values for the force-directed algorithm and the buttons load new graphs and apply various techniques. This will hopefully serve as a tool for teaching network analysis and visualization principles during my Gephi courses and general Networks in the Humanities presentations.

Notice this includes a pretty straightforward way to load CSV node and edge lists as exported from Gephi.

It also includes a pathfinding algorithm built for the standard data structure of force-directed networks in D3. This requires the addition of .id attributes for the nodes, however.

Now with Clustering Coefficients!

Also, it loads images for nodes but the images are not in the gist. The code also refers to different network types but the data files on Gist only refer to the transportation network.

I got trapped by a lambda function

I consider myself a medium-to-experienced Python programmer (I am using python for 6 years). Today I've lost almos one hour in a very stupid bug with lambda functions. See what happend:

Tkinter, Buttons and Callbacks

I was building a very simple Tkinter GUI (I'm not an GUI expert, so I code in Tkinter because it is easy and simple, but I myself think that it is ugly).
