Agent-Less System Monitoring with Elixir Broadway
We’ve started working on something that will be a critical component the Opsmaru platform. This part requires having proper infrastructure monitoring for several reasons. While Opsmaru has health monitoring for every cluster managed by the platform, it doesn’t give us deep insights into the metrics of the systems. Up until this point we’ve delayed the […]
Math Academy, part 1: My eigenvector embarassment
An example Math Academy status display. The student is about to begin a new lesson; that lesson has two other lessons as prerequisites. The “3644 XP” represents the student’s activity since subscribing to the service, roughly equivalent to about 60 hours for a typical student. Click for a higher-resolution version. This all started because I […]
Coral USB Accelerator with Google’s Edge TPU
Description The Coral USB Accelerator adds an Edge TPU coprocessor to your system, enabling high-speed machine learning inferencing on a wide range of systems, simply by connecting it to a USB port. Performs high-speed ML inferencing The on-board Edge TPU coprocessor is capable of performing 4 trillion operations (tera-operations) per second (TOPS), using 0.5 watts […]
Show HN: Welcome, Cot: the Rust web framework for lazy developers
18 February 2025 Cot was born out of frustration – the kind that every Rust developer feels when searching for a batteries-included, Django-like web framework that just handles the basics for you. While Rust is a really mature language, the web ecosystem is still sort of lacking. Let’s change that. Motivation There is a variety […]
These years in Common Lisp: 2023-2024 in review
This is a personal pick of the most interesting projects, tools, libraries and articles that popped-up in Common Lisp land in the last two years. Newcomers might not realize how the Common Lisp ecosystem, though stable in many ways, actually evolves, sharpens, tries new solutions, proposes new tools, ships new libraries, revives projects. And everyone […]
The Ideal Candidate Will Be Punched In the Stomach
What’s the craziest thing you’ve ever done? Published February 13, 2025 “It would feel so good to say goodbye, when I’m with you I wanna die!” Typically you would try to time your footsteps to the beat of the song—a permanent habit from your time in a marching band—but the tempo of this one is […]
Reviewing the Cryptography Used by Signal
Last year, I urged furries to stop using Telegram because it doesn’t actually provide them with any of the privacy guarantees they think it gives them. Instead of improving Telegram’s cryptography to be actually secure, the CEO started spreading misleading bullshit about Signal®. Since then, I’ve been flooded with people asking me about various other […]

Linux’s Sole Wireless/WiFi Driver Maintainer Is Stepping Down
Days after a DRM driver developer orphaned his drivers due to health reasons in stepping down, the sole maintainer at large of the Linux wireless (WiFi) drivers is stepping down and without any immediate replacement. Kalle Valo who has been a Qualcomm Atheros engineer for more than the past decade and contributor to the Linux […]
