This is a code-reading and exploration post about the WebSockets side of Phoenix. It builds upon some of the tracing techniques showcased in the previous post, to observe some of the internals of Phoenix. It also features some tricks I commonly employ to debug WebSocket related issues. The title and nature of this…
It's not about technology for its own sake. It's about being able to implement your ideas.
In the previous post we looked at how to emulate a CHIP-8 CPU with Common Lisp. But a CPU alone isn't much fun to play, so in this post we'll add a screen to the emulator with Qt .
More than a year passed since I had started to publish a series of interviews with Lisp hackers . It was a great project, but I'm going to...
CUDA 10 support has just landed in ClojureCUDA with the latest version 0.6.0.
WebSocket (WS) connections are pretty neat. I’ve gotten to play around with them before, both for personal and professional projects, but my view has mostly been at a high level and concerned mainly with the things that I can build on top of them. I haven’t spent much time digging through the protocol. I thought it…
The Rust ecosystem has made some cool progress on the embedded development front since my last article . Let’s take a look how we can build a much more ergonomical and safe API to one of the more popular real time operating systems - FreeRTOS - with a full testing and continous integration setup.
How the KV cache gives every AI conversation a physical weight in silicon, and what happens when the memory runs out.
Being able to peek into a process is a very helpful thing when we want to fully understand how a program behaves.
Happy with my recent breakthrough in understanding C integer divisions after weeks of struggle, I was minding my own business having fun writing integer arithmetic code. Life was good, when suddenly… zsh: segmentation fault (core dumped) .
It turns out my hopes were answered. First, Prechelt published another article that covers Tcl, Python, Perl, and Rexx. Also, Ron Garret (nee Erann Gat) did a follow-up study in which he asked programmers to write Prechelt's test program in Lisp. His results show that the resulting Lisp programs ran faster on average…
Should I teach myself to code or get a college CS degree? This is a question that many face. Software development is a field that is heavily reliant on skills. So surely teaching yourself to code should be enough right? Wrong.
This article is dedicated to discussing why it's so hard to detect the 'key up' or 'key release' event in a Linux terminal environment without relying on X server. Several techniques and code examples will be shown that are capable of detecting the keyup event on Linux (with and without an X server), but all…
When you start out as a developer there’s an overwhelming amount of things to grasp. First there’s the language itself, then all the quirks of the specific framework you’re using,and after that (or maybe before) we’ll throw front-end development into the mix, and somewhere along the line you have to decide to store…
An explainer for people who don't know computer science and are mildly curious
We ran into a big blocker when designing SpriteBox Coding, a learn-to-code game for kids ages 5+. For some kids, code was simply…

In the past five years or so, while the web development world was going mad with the JavaScript revolution – I stayed mostly indifferent, occupying myself with backend work and distracting myself with things like Kubernetes .
There is a popular movement on Choosing Boring Technology started by article by Dan McKinley, followed by some discussions on Hacker News…
There have been many different blog posts on the “State of the Web” , problems people face around tooling, and similar-style musings of late. This article is about summarizing my thoughts on recent events. Rather than yet another rant about the state of web development, this piece aims to pour some thought into what…
UPDATE (3/20/2015) If you read this, know that Vulkan has addressed every issue I raise in this article. See my postscript here .
A guide to effective pair-programming
Hey! Target reached: Bragging time! I mean, this is the irregular Emacs update … stats … report… thing… So, I’m gamifying Emacs development by setting myself a goal of…
“Don’t write clever code.” Why not? “Because it’s hard to understand.” People who say this think of clever code such as Duff’s Device: Duff's Device send(to, from, count) registershort*to, *from; registercount; { registern =(count +7) /8; switch(count %8) { case0: do{ *to =*from++; case7: *to =*from++; case6: *to…
It started with stb_image.c because it’s just crazy useful and avoids so much hassle in small demo programs. But that was just the gateway…
