In this essay, we are going to look at recursive algorithms, and how sometimes, we can organize an algorithm so that it resembles the data structure it manipulates, and organize a data structure so that it resembles the algorithms that manipulate it.
-- "Have you ever detected anyone trying to add a backdoor to curl?" -- "Have you ever been pressured by an organization or a person to add suspicious code to curl that you wouldn't otherwise accept?" -- "If a crime syndicate would kidnap your family to force you to comply, what backdoor would you be … Continue…
tldr; you can do jobs, queues, real time change feeds, time series, object store, document store, full text search with PostgreSQL. How to,...
On Friday I accepted a challenge to clone Reddit's /r/place in a weekend. And I did it, and its live, and its amazing: Being able to build this in a weekend isn't genius. Its possible because programming is made up of 2 activities: Making decisions (95%) Typing (5%) Reddit
Alone on a Friday night, in need of some inspiration, you decide to relive some of your past programming conquests. The old archive hard drive slowly spins up, and the source code of the glory days scrolls by... Oh no. This is not at all what you expected. Were things really this bad? Why did no one tell you? Why were…
The best APIs implement both permalink URLs based on identifiers for stable identification and search URLs based on names (and perhaps other values) for ease-of-use. Here's why.
An extensive tutorial on how to implement a neural network in JavaScript with deeplearn.js to perform machine learning in JavaScript. You can bring neural networks to your browser by using the performance benefits of WebGL. Deeplearn.js makes it possible to implement a WebGL powered neural network ...
Learn how to build a working Redux implementation from scratch. Our implementation won't cover every nuance, but we'll remove most of the mystery.
We normally think of git merges as having two parent commits. For example, the most recent Linux kernel merge as I write this is commit 2c5d955, which is part of the run-up to release 4.10-rc6. It has two parents:
This post is the first of many to come on Apache Arrow, pandas, pandas2, and the general trajectory of my work in recent times and into the foreseeable future. This is a bit of a read and overall fairly technical, but if interested I encourage you to take the time to work through it.
Go 1.9 adds type aliases, bit intrinsics, optimizations, and more.
The buzz around Mastodon’s federated social network has made me nostalgic about bulletin board systems in the early nineties. It was an era that is unknown to most people. It was social networking ...
Today I landed yet another small change to libcurl internals that further reduces the number of small mallocs we do. This time the generic linked list functions got converted to become malloc-less (the way linked list functions should behave, really). Instrument mallocs I started out my quest a few weeks ago by…
When Git first came onto the scene in the mid 2000's, I was initially skeptical because of its horrible user interface. But once I learned it, I appreciated its speed and features - especially the ease at which you could create feature branches, merge, and even create commits offline (which was a big deal in the era…
This post describes how to write a simple Hello world bootloader
WebGL is, all things considered, a pretty decent API. It’s not a great API, but that’s just because OpenGL is also not a great API. It gives you raw access to the GPU and is pretty low-level. For those intimidated by something so low-level, there are quite a few higher-level engines like three.js and Unity which are…
I like Git. I use it all the time. As I sometimes do, I recently took some time to really dig in, read through documentation, and review my global Git configuration. Welcome to my fourth stack...
I made a new years resolution to read at least one C source file from OpenBSD daily.The goal was to both get better at C and to contribute more to the base s...

How we, at GitLab, write VueJS, one year later.
At this point we have a TCP/IP stack that is able to communicate to other hosts in the Internet. The implementation so far has been fairly straight-forward, but missing a major feature: Reliability. Namely, our TCP does not guarantee the integrity of the data stream it presents to applications. Even establishing the…
