Run Python in your HTML
PyScript is a framework that allows users to create rich Python applications in the browser using HTML’s interface. It aims to give users a first-class programming language that has consistent styling rules, is more expressive, and is easier to learn. PyScript is just HTML, only a bit (okay, maybe a lot) more powerful, thanks to the rich and accessible ecosystem of Python libraries.

Many software companies are a joke
Many software engineers are paid to do very little work. A lot of my time was spent attending useless meetings, preparing boring slides, making goofy excel sheets and Gantt-charts. Even my major solo side project was more complex than our software at work. Do not be surprised when a project you were given 1 year to work on can be replicated by a freelance developer outside the corporate atmosphere in 2 months.

Twitter thread about GraphQL got a lot of attention yesterday. The author of the thread claimed that GraphQL makes your public API equal to a generic graph database.

Neon — Serverless, Fault-Tolerant, Branchable Postgres
Compute is fully client-compatible with Postgres because it is Postgres! Neon adjusts the amount of resources dedicated to the compute. Compute activates on an incoming connection and shuts down to save resources on inactivity. On Demand Scalability. We separated storage and compute to make on demand scalability possible.

Ancient Earth
Some elements of this visualization are not adjusted for time (eg. cloud and star positions). The locations are accurate to ~100 km. The coloring of the maps is based on elevation and bathymetry: dark blue = deep water, light blue = shallow water; dark green, green, tan, brown, white = ground in increasing order of elevation.

The Niche Programmer
For the vast majority of his programming career, I've been a mainstream developer. But then one day in 2018 I got a job where I had to learn Clojure. I had no idea that there would be something without a C-like syntax. So many parentheses, such seemingly condense code. Crazy. I learned it and then wrote Clojure for almost 3 years at that company.

How I fell in love with low-js
A few years ago I was working on a project written in style still common for today: python backend serving a REST API (public btw) using framework-of-the-day. It was horrible. We ended up using something very fringe - there were real performance and complexity problems. And to this day I believe all our problems stemmed from the base architecture.

How a Single Raspberry Pi made my Home Network Faster
Raspberry Pi project Pi Hole is the gatekeeper to our home network. The Pi Hole blocks Ads, Malware, and overreaching metrics collection network-wide. Since I switched to SimpleAnalytics to stop tracking people on our websites I thought to apply the same principle to our network. I am so impressed with the performance and security of the Pi Hole project.

The 60 minutes has run out, the puzzle is unsolved and we head off to the next test. "Oh, it's not about that, this is an asshole test. You see who turns into an asshole under pressure and they don't make it"

My students cheated... A lot
Last semester I witnessed the worst cheating in a course I’ve ever seen. Overall my students are really great. There was a lot of cheating, so the story is long. People cheat in college for lots of reasons. I don’t condone the behavior. When cheating happens, it can reflect on me as an instructor.
