Recently a friend asked me what I look for when considering a new job. When I interview for a new software engineering job, I’m usually participating in two interviews at once. The company is interviewing me, and I am interviewing the company. Both interviews are equally important to me. Sometimes I am nervous about appearing […]

Dangerous? Really? Well, not if you understand how it works. Note: I’m not the first to write about this subject. When writing a function in Python, it’s handy to use default argument values like this: And you think this will provide an easy way to let lazy callers pass no arguments to your function, and […]

What does it take to write high quality code? Here’s a little table that I use to judge my own code quality: Future axes to add: Ratio of the initial development cost to the long term maintenance cost Code testability: Code can be manually tested, code can be tested with automation, code can be tested […]

Treading on Python by Matt Harrison provides a basic introduction to the Python programming language for programming novices. Background of the reviewer I have been writing code professionally for 10 years. I’ve spent most of my time in C++, but I’ve written a handful of small Python scripts (less than 100 lines) and a couple […]

Nothing says Merry Christmas like Project Euler. Here’s a nifty solution to Problem 79 that uses Python and Graphviz.
