The Rails community has had a few high-profile security issues this week. They are well-summarized, with an alarming list of what follow-ons to expect, by Patrick McKenzie: What the Rails Security Issue Means for Your Startup.
For the last month, I have been working through Nand2Tetris: The Elements of Computing Systems; Building a Modern Computer from First Principles . I recently completed part 1. This first half of the text illuminates the process of building a computer purely from elementary logic gates. Each chapter is comprised of an…
So what is Flask-Admin ? I'm seeing a lot of misunderstanding about the project. Typical Flask advice regarding administrative interface looks like this - "just write one from scratch, all these CRUD frameworks are very limiting". Well, I can't agree with the opinion and going to explain why.
In this document, I describe what is, in my humble but correct opinion, the best known algorithm for threading messages (that is, grouping messages together in parent/child relationships based on which messages are replies to which others.) This is the threading algorithm that was used in Netscape Mail and News 2.0…

Note: The focus of this article is to explain the process of reverse engineering, and it is not continually updated to reflect ongoing changes in Facebook APIs. If you are looking for updated details, consider basing your work on open-source projects like mautrix/meta , which is developed by my employer Beeper .
Extensions allow Postgres to be customized and extended in powerful new ways. Here we find a tour of extensions and how they can make Postgres into much more than a relational database
Background In 2015 I worked as a consultant at a large company in Lund. My position was with the build team and one of our responsibilities...
A few months ago, I decided to implement set operations on curved regions. I had the the canonical textbook on computational geometry , which described approaches for polygons comprised of straight lines, and it seemed like other projects had extended these techniques to parametric curves . I figured it would take a…
You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.
Have you ever wanted to write your own compiler? ... yes? ... of course you have! I've always wanted to have a go at writing a compiler, and with the recent release of WebAssembly, I had the perfect excuse to have a go.
Almost five months ago, I wrote a blog post about my new programming language, Hackett , a fanciful sketch of a programming language from a far-off land with Haskell’s type system and Racket’s macros. At that point in time, I had a little prototype that barely worked, that I barely understood, and was a little bit of…
Let's build a query engine from scratch. In about 100 lines of Javascript, we'll support joins, indexes, and find our answer for Arnold!
An in-depth introduction to Reason/OCaml and the official React.js bindings, aimed at JavaScript developers.
A small Figma war story.
When you think about the Fibonacci sequence, you probably imagine a swirling vortex of oscillating points stretching outwards to infinity: Okay, no, obviously you don’t. Yet.
Many modern virtual machines include either a fast interpreter or a fast baseline compiler. A baseline compiler needs extra memory and is li...
How learning the Clojure programming language three years ago changed my life
My cofounder Joe and I recently finished SICP. It was a mind-bending experience: you start from just 3 concepts, and you recursively build up algebraic equation solvers, circuit simulators, 4 interpreters, and a compiler.
There is a whole chunk of the Dolphin project that most users don't know about and have no interactions with. Most of the blog's articles focus on user visible features: improvements in the emulator core, or accuracy changes that allow non playable games to finally work properly. We seldom talk...

As an intermediate beginner, the basic tutorials are too easy now. But it's hard to figure out what to build for practice, and how big those projects should be.
