Why do interviewers ask linked list questions?
A couple years back I gave a talk on researching software history, using “linked list interview questions” as an example topic. Since referring people to a video is less accessible than just writing a blog post, I’ve reproduced the question here. So why do interviewers like to ask linked list questions? If you ask…

No one gives a shit what programming language you use
I’ve had it up to here (gestures at nose level) with the bullshit around programming language elitism. Back when I thought it mattered I was just as bad as the bullshit I’m seeing today…

An Intuition for Lisp Syntax
Every lisp hacker I ever met, myself included, thought that all those brackets in Lisp were off-putting and weird. At first, of course. Soon after we all came to the same epiphany: lisp’s power lies in those brackets ! In this essay, we’ll go on a journey to that epiphany.

API versioning has no “right way” (2017)
API versioning is a really difficult topic, and sometimes seen as a merely religious debate. It’s done differently at different companies, and different teams within different companies often vary. Some folks move from approach A to approach B, and when approach B solves their specific issues they act like

The Mediocre Programmer
The Mediocre Programmer is a book about the journey of becoming a better programmer. But before we can become better programmers we have to pass through being mediocre programmers. Mediocre doesn't mean a bad programmer --- far from it. It means lacking skill. As beginners we start our journey full of fresh ideas of…

Fixing memory leaks in popular Python libraries
I was recently able to make a minimal example that reproduced a Celery memory leak. The memory leak would happen on the main Celery worker process that’s forked to make child processes, which makes the leak especially bad. Issue #4843 has been around for 3+ years and has 140+ comments, so this one has been causing a…

Conway's Game of Life on FPGA
When learning a new programming language, I like having a well defined yet non-trivial problem to solve. Conway’s Game of Life (GoL) fits this definition. It has enough depth to uncover various tradeoffs. So naturally, when I picked up Chisel hardware description language (HDL), I wanted to build Game of Life in FPGA…
