Pretend that you’ve opened this book (although you probably have opened this book), just to find a huge onion right in the middle crease of the book. (The manufacturer of the book has included the onion at my request.)
In these videos, I talk about how VGA signals work and build a circuit that provides the correct timing of sync signals so that a monitor recognizes the signal and displays an image stored on an EEPROM.
I believe Python's ExitStack feature does not get the recognition it deserves. I think part of the reason for this is that its documentation is somewhere deep down in the (already obscure) contextlib module because formally ExitStack is just one of many available context managers for Python's with statement . But…
Note: I copied this from http://misspiggy.gsfc.nasa.gov/tao.html and stripped out all of the IMHO extraneous formatting. ---Alex
Pico-8 and the retro-gaming trend
Late last year I released posuto, a package presenting Japanese postal code data in an easy-to-use format. It's based on data released by Japan Post, which is infamous for being widely used but hard to parse.
Some time back, I was working on a project where it felt like the timebomb of technical debt was exploding in our faces. We couldn’t refactor the whoositz because of the whatsitz and when we asked about the whatsitz no one knew about the whatsitz and how it exactly worked with the whoositz and there certainly weren’t…

Example based guide for text processing with Perl from the command line
From Vim To IntelliJ In the beginning, a love affair For the last 10 years or so, I have been a die-hard Vim user. I was introduced to Vim…
tl;dr: With the Netpbm file formats, it’s trivial to output pixels using nothing but text based IO
These are my notes after learning the Paxos algorithm. The primary goal here is to sharpen my own understanding of the algorithm, but maybe someone will find this explanation of Paxos useful! This post assumes fluency with mathematical notation.
This summer I’ve been interning at Pusher , and have been writing a lot of Go. It’s been a bit of a change coming from a Haskell background, so I decided to write up my thoughts now, at the end.
So here's an interesting thing. Certain commit hashes are rapidly heading toward being illegal on Github .
Yesterday, I read a phenomenal paper on how disruption free release at Facebook.
Haskell programmers spend a lot of time talking about type safety . The Haskell school of program construction advocates “capturing invariants in the type system” and “making illegal states unrepresentable,” both of which sound like compelling goals, but are rather vague on the techniques used to achieve them. Almost…

The famous fast inverse square root is some mysterious code not written by programming legend John Carmack to calculate a fast approximation of $1/\sqrt{x}$:
TLA+ is a formal specification language that you can use to verify programs. It’s different from other formal verification systems in that it’s very pragmatic. Instead of writing proofs…
In this post I'll outline several ways to build containers without the need for Docker itself including buildkit, kaniko, GitHub Actions, GitLab and Jenkins
Debugging without source or symbols, alternatively, "Where there's a will there's a way"
