I wish Asciidoc was more popular
I've been using Markdown for a long time, and have grown accustomed to it. It has various quirks, features, and oddities, but what doesn't…

Yet another keyboard post, or, introducing ErgoNICE
I made a custom split mechanical keyboard! Because it's me, this involved things like contributing to a PCB design tool and discovering a ridiculously optimized way to read a keyboard matrix.

Even more hindsight on Vim, Helix and Kakoune
Oh my… 2023 has been such a trek so far… If you have missed my previous article about my thoughts about editors and development platforms, I think it’s probably the moment to have a look at it.

Writing a Package Manager
Without spending a year on it.

Git files hidden in plain sight
I doubt that it is a good practice to ship the public key used to sign things in the repository in the repository itself

System settings that aren’t in System Settings
Where would you set the default call handler for macOS? And where in System Settings do you set the default web browser?

Using command line to process CSV files (2022)
Process CSV files from the command line with awk, sort, and grep: pull out fields, order rows, and filter data without a spreadsheet or a script.

Emacs GUI Library
Lately, my Magit buffer broke once again because of something weird going on with major mode, and I couldn’t stash or commit hunks unless the point was at the beginning of the line. That once again reminded me that Emacs UI is not really a UI, all of it is mere text with a bunch of properties slapped on top.

LLM Python/CLI tool adds support for embeddings
LLM is my Python library and command-line tool for working with language models. I just released LLM 0.9 with a new set of features that extend LLM to provide tools …

How to prioritize tasks?
Shipping products is hard. What makes it hard is that typical products involve multiple teams and multiple dependencies. Navigating these challenges is non-trivial. There are technical challenges to overcome, but those are typically not the biggest blockers. (There are enough smart people in the room to take care of…

Writing as a form of thinking
The cost of delegating the writing process to other entities (like LLMs)

Using computers more freely and safely
The most important step is the first one. Humanity didn't get good at building houses by building the same house a million times. We built lots of different houses and learned from each other's failures. Gravitating away from monopolies is a way everyone can help improve software, regardless of our abilities or needs.

The Compact Calendar 2023-2024
The Compact Calendar presents days as a continuous candy bar of time. Weeks are presented as a stack of available time with no gaps, making it easier to count-out days naturally as you think.

What is the randomart image for?
When you generate an SSH key (like I did when looking at signing commits with SSH keys ), you get a “randomart image” from ssh-keygen . These things:

JPEG-XL vs. AVIF and Others: 27 Images Compared
The current debate surrounding AVIF versus JPEG XL needs some third-party quantitative data to support arguments on either side. I've compiled a dataset of 27 high-resolution photographic images to compare performance across them all at a wide fidelity range.

Improving Emacs Isearch Usability with Transient
Emacs incremental search (isearch) has an embarrassingly rich feature set. That said, I rarely use isearch beyond its basics for the twofold reasons: There are many isearch commands that are...

Ottopot, a sophisticated DIY MIDI controller
This is the ottopot. It's a MIDI controller I made with nothing but 8 dials. However, the dials I made in the highest quality that I possibly could. There are 2 things in particular that I haven't seen in any other similar devices: High resolution with 14bit MIDI CCs (12bit effective resolution) and a quasi-1:1…

Writing a Profiler in 240 lines of pure Java
A few months back, I started writing a profiler from scratch, and the code since became the base of my profiler validation tools. The only problem with this project: I wanted to write a proper non-safepoint-biased profiler from scratch. This … Continue reading →

My 2022 self was wrong about meditation, monitors, and sleep
Introduction When I read Richard Hanania’s Reflections on 2022 in which he listed a bunch of major topics he changed his mind about, I realized that I really admired him for doing this. Then, immediately afterwards, I thought “Wait, am I worse than Hanania? The person who made the entire twitter angry at him more…

Digital clutter: Learning to let go and stop hoarding terabytes
Learning to let go and stop hoarding terabytes: Sharing my journey of downsizing my digital storage, letting go of terabytes of data, and moving away from a NAS setup. I decided to use an external Thunderbolt SSD enclosure and an M.2 NVMe SSD to store my data locally. For cloud backup and encryption, I used the Arq…

Sorting in Emacs
In this article, we will perform a series of hands-on experiments that demonstrate the various Emacs commands that can be used to sort text in different ways. There is sufficient documentation available for these commands in the Emacs and Elisp manuals. In this article, however, we will take a look at some concrete…

My User Experience Porting Off Setup.py
In the past week I went to add Python 3.12 support to my zstandard Python package. A few hours into the unexpected yak shave / rat hole, I decided to start chronicling my experience so that I may share it with the broader Python community. My hope is that by sharing my (unfortunately painful) end-user experience that…
