Personal Software Is Becoming a Trend (xuanwo.io)
I've come across some posts about personal software recently. Lee Robinson calls it "Personal Software," whereas Edmar Ferreira refers to it as "Selfish Software." Lee emphasizes the personal aspect, focusing on how it meets one's own needs, while Edmar wants to highlight that it's "selfish," created without external customers in mind. The common thread is that both are discussing the idea of building software for oneself.
Building an "Easy" Web Application (rudyfaile.com)
I decided to spend my Fourth of July weekend transforming a small Python utility I wrote a couple of years ago for work. The idea was simple: make the tool more accessible for co-workers who use it by turning it into a web application.
I coded a Pascal compiler for transputer as a teen in 1993 (nanochess.org)
Once upon a time when I was a teen, I wrote an almost full Pascal compiler for a transputer processor (the FILE type wasn't never completed). The Pascal language was designed in 1971 by Niklaus Wirth, as an educative version of the language Algol, which dates from 1960. It reached its highest popularity with Turbo Pascal and Delphi from Borland. Borland was founded by Philippe Kahn, who studied Pascal with Wirth.

Blogging on Paper (2017) (conroy.org)
I recently published my first blog post of 2017. The fact that it was posted exactly one year after my last post was mere coincidence. Looking over the the last six years of my blog, it's hard to really call it a blog at all.
Building a T1D smartwatch for my son from scratch (andrewchilds.com)

Testtrim: A testing tool that couldn't test itself (until now) (fenniak.net)
Today, we’re going to deep-dive into the kind of thing you can only “invest” time on if you’re a single engineer working on a project with no supervision. I just finished a crazy complicated development effort in my project, testtrim, and all I want to do is talk about how surprised I am that it actually worked.
Lessons from building a small-scale AI application (thelis.org)
ChatGPT heralded a seismic shift in software, and one that I felt compelled to understand. So, over the past year, I’ve been building an AI assistant for my past-CEO-self as a pedagogical exercise. It answers questions, gets status reports, and summarizes what’s going on. Reflecting on what I know now, here are my takeaways over the past year.
I wrote my own “proper” programming language (2020) (mukulrathi.com)
The diagram above is the compiler for the language Bolt we’ll be building. What do all the stages mean? I have to learn OCaml and C++? Wait I haven’t even heard of OCaml…
How I Automatically Catalog My Game Collection from Pictures (medium.com)
I’ve long been a collector of classical computers, software and period tech literature — a hobby which has given me a lot of pleasure, nostalgia, and some surprising opportunities. However, maintaining an up-to-date catalog of everything has become increasingly difficult.

How do non-software engineers feel upon reflection, about their degrees? (ycombinator.com)
To set the scene: I wanted to build my own devboard for my own projects. I'm sat here looking at my screen after having opened KiCAD with some of the documentation for an STM32H7 MCU. It dawns on me that I have absolutely zero clue of what I am looking at and have no idea where to start beyond watching youtube. Here I am now writing this.

My approach to running a link blog (simonwillison.net)
I started running a basic link blog on this domain back in November 2003—publishing links (which I called “blogmarks”) with a title, URL, short snippet of commentary and a “via” link where appropriate.

Ask HN: What are you reading/learning/working on over the holiday break? (ycombinator.com)
This time of the year many people take time off to spend time with family and have extra free time to work on their own stuff (Python was famously created as a Christmas break project), so I’m curious how you’ll be using this extra time?
