This post could also be called “Or how to do React in Python” or “HTML as a function of state”. Most people use templating libraries like jinja2 to render HTML. I think that’s probably the best way to do it in production. However, for very simple / internal / proof-of-concept apps, I wanted to generate the HTML directly from Python functions to avoid needing extra files. I tried using f-strings to do that, but it gets messy pretty quick..

Upon his death in 1543 in Frombork, Poland, Copernicus was buried in the local cathedral. Over the subsequent centuries, the location of his grave was lost to history. There were several unsuccessful attempts to locate Copernicus’s remains, dating as far back as the 16th and 17th centuries. Another failed attempt was made by the French emperor Napoleon after the 1807 Battle of Eylau. Napoleon held Copernicus in high regard as a polymath, ma..

One of jOOQ’s key features so far has always been to render pretty much exactly the SQL that users expect, without any surprises – unless some emulation is required to make a query work, of course. This means that while join elimination is a powerful feature of many RDBMS, it isn’t part of jOOQ’s feature … Continue reading A Hidden Benefit of Implicit Joins: Join Elimination →

Is there a way to generate true random numbers automatically? Of course you can go to random.org to generate if you need so. But I want to run a program in the background that constanly generates random numbers in order to use them in meaningful data. Is there a way to do this? Or should I use the random number site as a gateway to do so?

Disclaimer: views expressed are my own and are not endorsed by my employer. It’s a famous joke that naming things is one of the hardest problems in computer science . I think this alludes to a fundamental truth behind so many of the problems I encounter every day as a software engineer. Let me ruin the joke and reword it a bit. The hardest problem in computer science is deciding whether two things are the same thing, or different. I d..

pg_rman: a backup and restore management tool for PostgreSQL

The goal of the pg_rman project is to provide a method for online backup and PITR that is as easy as pg_dump. Also, it maintains a backup catalog per database cluster. Users can maintain old backups including archive logs with one command. We’ve always been doing our Postgres backups the rudimentary way via pg_dumpall, which works and is purely logical (one can restore across different Postgres versions), but pg_rman maintains a catalog ..

I recently got a copy of RPG Maker MZ and have been making some small games in there in my free time. I bought it with the intention to use it for a larger scale project I had been wanting to do for a while, but every time I bring it up to someone who has had experience making games, it's always either just no reaction or a kind of side-eye situation where they kinda poke fun at it. I know it isn't the most advanced tool, but it clearly h..

Change point detection (CPD) in time series analysis is an essential tool for identifying significant shifts in data patterns. These shifts, or “change points,” can signal critical transitions in various contexts. While most CPD algorithms are adept at discovering historical change points, their sensitivity in detecting recent changes can be limited, often due to a key parameter: the minimum distance between sequential change points. In thi..

I spent a week looking at MySQL/MariaDB internals along with ~80 other devs. Although MySQL and MariaDB are mostly the same (more on that later), I focused on MariaDB specifically this week. Before last week I had never built MySQL/MariaDB before. The first day of this hack week, I got MariaDB building locally and made a code tweak so that SELECT 23 returned 213, and another tweak so that SELECT 80 + 20 returned 60. The second day I....
