Context It’s not often I get excited about programming languages since meeting Ruby in 2015. Way before that, drowning in misery of writing university course works in Java, has pushed me away from development. Ruby’s freedom and expressiveness was what pulled me back, and its style has kept me in. I was on the lookout…
One great question in office hours led me to delete a whole class.
An in-depth look at Data-Oriented Architecture (DOA): monolithic data stores vs microservices, scaling benefits, and real-world case studies.
It was more fun than I expected! I treated this seriously and I was well prepared, and it paid off. The kids were interested and I think they might even remember something.
Battlefield 3’s Battlelog system is an interesting web application that many of us missed. Here is why it’s amazing and worth a look at.
4-day coding marathon
A short story about Lisp, technology, and human progress.
Most high school students in the United States learn about matrices and matrix multiplication, but they often are not taught why matrix multiplication works the way it does. Adding matrices is easy…
Today, we will meet a spiky-haired nerd named Corey Dumm, who normally lives within Markdown code fences. We will get to know him a bit, smile with him when his fences hold and weep quietly when misfortune strikes.
I booted the arm64e kernel of macOS 11.0.1 beta 1 kernel in QEMU up to launchd. It’s completely useless, but may be interesting if you’re wondering how an Apple Silicon Mac will boot.
Thinking about writing your own Python implementation? Congrats, there are plenty out there 1 , but perhaps you have something new to bring to the table. Writing a fast Python is a pretty hard task, and there’s a lot of stuff you need to keep in mind, but if you’re interested in forging ahead, keep reading!
font-size is the worst. It’s a CSS property probably everyone who writes CSS has used at some point. It’s pretty ubiquitous. And it’s super …
I keep seeing discussions that equate zig's level of memory safety with c (or occasionally with rust!). Neither is particularly accurate. This is an attempt at a more detailed breakdown.
Why not "why not" comments? Not why "not comments"
As programmers we occasionally find ourselves in “Programmer’s Hell”, where our regular abstractions fail to satisfactory solve certain recurrent problems.
I've worked on many projects throughout my career as a software engineer. However, Helix - Uber's Rider app rewrite in 2016 introducing Swift and RIBs - stands as the craziest project by a margin. This is my story and some of my journal entries from the time. Prologue It's
TL;DR: I built a wifi-equipped water gun to shoot the pigeons on my balcony, controlled over the internet by a python script running openCV reading the camera image of my old iPhone. Introduction The pigeons in my backyard find particular pleasures in voiding their excrements onto my balcony. Dissatisfied with this…

Generating a Universe with One Line of Code
In 1995 Netscape partnered with Sun Microsystems to create interactive websites . Famously Brendan Eich spent only 10 days to create the first version of JavaScript - a dynamic programming language with a roughly syntactic lineage from Sun’s Java language. As a result of this partnership Sun held the trademark…
A common refrain is that Emacs is an operating system (OS). This isn’t true, but what invites comparison to an OS is its ability to orchestrate applications and utilities above the OS kernel...
My unscientific, incomplete, thoroughly biased view of interesting things that happened with Clojure in 2014.
Best Practices vary from environment to environment, and there is no One True Answer, but still, this represents a consensus from #git and in some cases helps you frame the discussion for the generation of your very own best practices.
