Today I finally released the project I’ve been working on for the last two years at MIT CSAIL : An HTML-based language for creating (many kinds of) web applications without programming or a server backend. It’s named Mavo after my late mother ( Ma ria V er o u), and is Open Source of course (yes, getting paid to work…
Django is a powerful framework used in many great projects. It provides many batteries, that speed up development and therefore reduces the price of it. When a project becomes large and is used by many users you inevitably will run into performance problems. In this guide, I will try define potential problems and how…
When the textile industry arose in the 18th century, craft was the norm in manufacturing. As the industrial revolution progressed, one after another sector of the economy made the transition from c…

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…
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 .
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 .
In the last few months I taught three graduate mini-courses about string diagrams and graphical linear algebra – at Phd Open in Warsaw, a winter school in Estonia, and a graduate school in Le…
A while back I wrote an OSS Spotlight post about the Swagger project. In short, Swagger is “the world’s most popular API tooling”. It’s a powerful open source framework back…
I recently had a problem where part of the solution was to do a series of pointer accesses that would walk around a chunk of memory in pseudo-random order. Sattolo's algorithm provides a solution to this because it produces a permutation of a list with exactly one cycle, which guarantees that we will reach every…

This Re-frame tutorial walks you through the main parts of Re-frame's structure, how they work together, and how they help you succeed in the long run building your single page application.
Robert C. Martin (Uncle Bob) thinks that defects in safety-critical systems are caused by a lack of developer professionalism. I think he's wrong.
In a previous blog post, I observed that one of the medium-termpossibilities we’re seriously considering for NTPsec is moving theentire codebase out of...
Traditionally, software is produced in this way: write some code, maybe do some code review, run unit-tests, and then hope it is correct. Hard experience shows that it is very ...
Recently Slack on the desktop has been going through an awkward adolescence. Instead of flailing limbs and pitch squeaks, ours has manifested in ways rather more grim: inexplicably failing to render content, reloading during common operations, and error screens that aren’t actionable. The only silver lining has been…
We are archiving Atom and all projects under the Atom organization for an official sunset on December 15, 2022.
RECENTLY I've been paying attention to the BuckleScript compiler from OCaml to JavaScript (ES5, to be exact). I'm seeing some significant a...
It's a little known fact that the PostGIS geography type since PostGIS 2.2 (well was introduced in 2.1 I think but had a bug in it until 2.1.4 or so), supports any spheroidal spatial reference system that measures in degrees. When an srid is not specified, it defaults to using 4326, Earth WGS 84 long lat.

Earlier this month I wrote about how Windows 10 holds a lock during too much of process destruction, which both serializes this task and causes mouse-cursor hitches and UI hangs (because the same l…
Update: All needed files for this tutorial can be found in the GitHub repo linked in the bottom of this page. I noticed that a lot of people are creating graphical programs to the Commodore 64 agai…
