I’ll just leave this here… Python 3.6 Python 2.7 Erlang R23 (On this one I can include the entire output.) Hey, Python! What the actual fsck is going on here?!? Jeebus… The Good Idea Fairy came along and convinced the webtarded among you to start throwing kitchen sink features in (“walrus operator” — yeah, great […]

Erlang: FizzBuzz in Python vs Erlang — a discussion about conditionals
I’ve had a few discussions with beginners over the last few months that often come to center around not really understanding the conditional branching constructs in Erlang, so I decided to do a video on it using “FizzBuzz” as the central example. The traditional if/else if/else boolean paradigm is quite different from Erlang’s concept of […]
Iterators? We Don’t NEED No Stinking Iterators!
Every so often a request for “implementation of iterators for maps” over hashes/maps/dicts or some other K-V data structure appears on mailing list for a functional langauge. I’ve spent years making heavy use of iterators in imperative languages, and the way they fit into Python is really great. For Python. I totally understand where some […]
Binary Search: Random Windowing Over Large Sets
Yesterday I came across a blog post from 2010 that said less than 10% of programmers can write a binary search. At first I thought “ah, what nonsense” and then I realized I probably haven’t written one myself, at least not since BASIC and Pascal were what the cool kids were up to in the […]
Don’t Get Class Happy
If you find yourself writing a class and you can’t explain the difference between the class and an instance of that class, just stop. You should be writing a function. This antipattern — needless classes everywhere, for everything — is driving me crazy. Lately I see it in Python and Ruby a good bit, where […]
Version String Comparison in Python
Comparing and sorting version strings in Python scripts has come up a few times lately. Here are some simple approaches. These examples assume that the version strings will be numeric representations and not include elements like “rc-1” or “alpha” or whatever. If your problem includes these kinds of elements, don’t worry — they are solvable […]
ODFapper 0.04 for Django on Unix
I’ve pulled the most common bits out of the Django views where I had rendered ODFs before and have the itty-bitty beginnings of an ODF handling/rendering library started now. “Library” is a bit of a stretch, since its only a few functions and a Bash script, but it abstracts the most mysterious/tedious parts of ODF […]
