The Walkie-Textie is a simple handheld device with a 12-key keypad and OLED display that allows you to send and receive text messages using the LoRa wireless protocol. It's ideal for situations where there's no mobile signal, such as when you're camping or hiking in a remote area, when you don't want the cost of a…
Large files bloat Git’s storage, slow down git clone , and wreak havoc on Git forges.
We just completed rewriting the Ghostty GTK application fully embracing the GObject type system from Zig and also verifying with Valgrind every step of the way. The result is a more feature rich, stable, and maintainable Ghostty on Linux and BSD.
Sometimes software takes a long time to compile just due to how much code it has, like in the LLVM project. But often a build is slower than it could be for dumb, fixable reasons. I’ve had the suspicion that most builds are doing dumb stuff, but I had no way to see it. So I’ve been working on a cross-platform tool to…
I wrote earlier about my dream of developing “single-handedly” on an iPhone. Then, I wrote some more about it . The dream still lives strongly! I am now coding single-handedly in any language on my iPhone SE model 2022. But although i still like pythonista I am now using a combination of three great apps that allow me…
pyx is a Python-native package registry from the creators of uv.
Update: APRIL FOOLS! by Kaue Silveira Here at Google, we invest heavily in development productivity research. In fact, our TDD resea...
A common source of confusion that I experience when posting my artwork on social media is: _why?_ Why use a plotter when you could use a printer? It's slower. Less exact. More expensive. It fails, far too often. Inkjet printers became ubiquitous in the 1980s because they solved nearly all of these problems. So why are…
The Four Daily Practices That Changed How I Live and Work
I installed Claude Code in June. I'd tried Cursor and Cline and Zed and a few others, but all of them felt clunky to me because I'm used to doing nearly everything in vanilla vim and my terminal. Claude Code was the first tool I tried that felt like it fit into my workflows perfectly rather than needing me to adapt to…
Writing about software, systems, and the craft of building things.
My experiment optimizing my sleep schedule around maximizing my Claude Pro subscription usage.
Shell tab-completions can be very handy, but setting them up is complicated by the fact that half your users would be using Bash-on-Linux, while the other half will be using Zsh-on-OSX, each of which has different tab-completion APIs. Furthermore, most users exploring an unfamiliar CLI tool using tab completion…
A personal guide on using AI Code Prep GUI, Cline, and various free AI web interfaces like Gemini, Grok, Deepseek, and Poe for cost-effective coding and debugging.
Building a completely offline AI workspace with local LLMs, sandboxed code execution, and browser automation — no cloud dependencies, maximum privacy.
An updated version of my user-level CLAUDE.md is featured in this post from December 2, 2025. I've been experimenting with LLM programming agents over the past few months. Claude Code has become my favorite. It is not without issues, but it's allowed me to write ~12 programs/projects in
A deep dive into local-first architecture, triggered by wondering why Linear feels so fast. Looking at the technical implementation, exploring tools like Jazz and Electric SQL, and explaining why my next app might not need API endpoints.
Cursed knowledge we have learned as a result of building Immich that we wish we never knew.
Lockfiles are an absolutely unnecessary concept that complicates things without a good reason. Dependency managers can and are working without it just the same.
I love dotfiles and I love sharing. But I have this weird feeling that sharing my dotfiles is too intimate and personal.
I’ve been using Tailscale for around four years to connect my disparate devices, servers and apps together. I wanted to talk a bit about how I use it, some cool features you might not know about, and some stumbling blocks I encountered.
A colleague spotted base64-encoded JSON in a long string of gibberish without any tools. I was amazed, until he explained how anyone can do it.
Twelve years ago, ECharts was first released on GitHub, planting the seed for an open-source journey.
After years on a VPS, I'm moving my self-hosted services home and using the opportunity to migrate to a more flexible and robust setup.
Discover how content-aware memory models, understanding flashcard semantics, will simplify the creation of future spaced repetition systems.
I have been exploring some new tools here and there. When I started watching Primeagen, I took a note of several tools that he was using and advocating for. One of them was tmux. What is tmux? tmux is a terminal multiplexer. What that means is you can have many terminals in one. According to tmux wiki: tmux is a…
Suppose you have an appetite for tilting at windmills. Let's say you love pain. Well then why not write a PDF parser today?
E ven before I started pressing buttons for a living I was always a pretty heavy computer user. When I was about 18 I started experiencing symptoms of RSI. At around the same time I learnt of the Dvorak keyboard layout, and so I switched, hoping it would solve my problems. It did, at least at the time, and so for the…
It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of quality, but I feel like I have a new freedom of expression which is hard to fully articulate. Claude Code has decoupled…
