But mostly I love C because when I write C I feel an intimate connection with my computer. To me, C has soul. In fact all my personal project are written in C, like the graphics rendering engines that I'm…
Ruby Central posted an extremely concerning “Incident Response Timeline” today, in which they make a number of exaggerated or purely misleading claims. Here’s my effort to set the record straight. First, and most importantly: I was a primary operator of RubyGems.org, securely and successfully, for over ten years. Ruby…
J. Nicholas Betley has led collaborative research seeking the neural basis of long-term sustained pain and finds that a critical hub in the brainstem holds a mechanism for stopping pain signals from reaching the rest of the brain. Their findings could help clinicians better understand chronic pain and lead to new…

As part of standard incident-response practice, Ruby Central is publishing the following post-incident review to the public. This document summarizes the September 2025 AWS root-access event, what occurred, what we verified, and the actions we’ve taken to strengthen our security processes.
Documenting my journey in trying to use my ESP32 on my phone through Termux
Anthropic research on data poisoning attacks shows a few hundred malicious documents can "backdoor" large language models of any size.
I bought a really small 8x8 LED panel a while ago because I have a problem. I just can’t resist a nice WS2812 LED panel, much like I can’t resist an e-ink display. These days I manage to stay sober, but once in a while I’ll see a nice cheap LED panel and fall off the wagon. It has now been thirteen minutes that I have…
While not an absolute requirement for modern graphics card support on Linux, Resizeable BAR support makes GPUs go faster, by allowing GPUs to throw data back and forth on the PCIe bus in chunks larger than 256 MB. In January, I opened an issue in the Raspberry Pi Linux repo, Resizable BAR support on Pi 5. Unlike most…
Apple’s Calculator leaked 32GB of RAM. The deeper failure is an industry shipping more software while producing fewer engineers capable of fixing it.
Let me make the argument why you should start self-hosting more of your personal services.
I always assumed that Python's str.splitlines() split strings by " universal newlines ", i.e., \n , \r , and \r\n .
Though I spend the majority of my time working with microcontroller class devices, I also have an embarassingly robust collection of single board computers (SBC), including a few different Raspberry Pi models, the BeagleV Starlight Beta (RIP), and more. Typically when setting up these devices for whatever automation…

How do two well liked companies, deutsche Bahn and adobe, advertise their subscriptions? Badly. Deutsche Bahn, the fully state-owned railway company, is a we
It’s unfortunately not uncommon for pedestrians to be killed by cars in the US.
We just raised $180 million in Series C funding, bringing our total funding to $240 million and our valuation to $2.5 billion. The round is led by Accel, with support from Meritech, Redpoint, Evantic and Visionaries Club. Corporate investors NVentures (NVIDIA’s venture capital arm) and T.Capital also
I’m entirely convinced that basically every developer alive today heard the adage “dress for the job you want, not the job you have” and figured that, since they always wear jeans and a t-shirt anyway, they might as well apply it to their systems’ architecture. This explains why the stack of every single company I’ve…
In November of 2024 I wrote a blog post titled "Is Python Really That Slow?", in which I tested several versions of Python and noted the steady progress the language has been making in terms of…
Meta open-sourced React over a decade ago to help developers build better user experiences. Since then, React has grown into one of the world’s most popular open source projects, powering over 50 m…
On June 30, 2025, Mark Brittenham and Susan Hermiller uploaded a preprint to the arXiv called “Unknotting number is not additive under connected sum” (and an updated version on Septembe…
I’ve been trying to slowly ease into using LLMs for coding help again lately (after quitting ), but something always feels off -- like we’re not quite on the...

Let’s say you decide to start a coding bootcamp. Your background is in pedagogy and you love teaching. Your parents were teachers. You find a co-founder, raise a bit of money, and pour your soul into your company. The first couple of years, students love your program. Positive feedback, extraordinary student outcomes…
The night we spent without control of our Twitter account.
In the last two weeks I spent over a dozen hours playing poker, primarily online at pokerstarsmi.com, and live at a local casino. You can view the last 1,000 hands I played here: https://poker.rchase.com I spent at least as much time reviewing my hands with
The five most popular JS frameworks – Angular, React, Vue, Svelte and Blazor – use different rendering strategies, and it shows.
