I’ve had a pleasure to work with Piotrek Jagielski for about two weeks on Clojure project. I’ve learned a lot, but there is still a lot to know about Clojure for me. In this post I’ll write what fasci
Before I go into the specifics of my record attempt, it is important for you to have some background information. Over the past few years I have been steadily acquiring server hardware to increase my knowledge of system administration and cyber security. This is not only for personal growth: it has also helped me…
This post is all about speculative compilation, or just speculation for short, in the context of the JavaScriptCore virtual machine.
A tip on how to add a target on your Makefile to list all available targets
I have a shameful confession to make: I have long neglected an open-source library that I maintain, clj-tagsoup .
Getting started with shaders: signed distance functions!

I love science. Not the “space is beautiful” faux-science, but the process of doing science. Hours spent calibrating equipment, cross-checking cites of cites of cites, tedious arguments about p-values and prediction intervals, all the stuff that makes science Go. And, when it does happen, the drama. I also want us to…
Fibers, Oh My! # Written by Dale Weiler, last updated Oct 5th, 2020 Twitter GitHub It’s been brought to the attention of many people in the game development industry that you can use fibers to parallelize your engines and games. This one presentation in particular: Parallelizing the Naughty Dog engine using fibers has…
A while back, I was trying to speed up some code which finds unique items in a collection. For example, transforming "AABBADCAB" => "ABDC" . There are two ways to do this efficiently - one is based on sorting, the other based on hashing. So, which is faster? I couldn't find the answer, so I ran some experiments and…
Better tooling, export maps and improvements to slots and context
Git 2.25.0 includes a new experimental git sparse-checkout command that makes the existing feature easier to use, along with some important performance benefits for large repositories.
A common thing in React development is that we want to store a bit of React state in localStorage, and re-initialize from that value on the next page-load. This quick tutorial shows you how we can build a custom hook that does exactly this!
Building a simple neural net in Java.

When I started my career, XML was ubiquitous. The meta-information in a Java JAR file - the manifest - follows a proprietary format. But Java EE designers built it from the ground up on XML: meta-information of all artifacts is in XML format e.g. web.xml, ejb-jar.xml, application.xml, etc. Java EE is one example I…
Git has a reputation for being confusing. Users stumble over terminology and phrasing that misguides their expectations. This is most apparent in commands that “rewrite history” such as git cherry-pick or git rebase. In my experience,…
Whenever discussing problems with programming today and potential solutions, invariably someone will pop up and declare that the problem is ...
Most WebAssembly tutorials and examples you will find online focus on using it inside the browser in order to accelerate various functionality of a website or web app. However, there is an area where WebAssembly is really powerful but not talked too much about: outside the browser usage scenarios. That is what we’ll…
When it comes to hashing, sometimes 64 bit is not enough, for example, because of birthday paradox — the hacker can iterate through random $latex 2^{32}$ entities and it can be proven that wi…
“Computers are all made out of logic gates”. We’ve heard that saying before. We also have a sense that logic gates are very simple machines, analogous to light switches even. This raises the question: how exactly do kind-of-light-switches come together to form computers ? How does “storing a variable” or “calling a…
Here’s why Rust gets so much love, straight from the Rustaceans themselves.
