Recently, a study made the Hacker News’ front page mentioning that 50% of U.S. vinyl buyers don’t own a record player. There was ample discussion on whether it was GenZ collecting aesthetic objects or a fashion statement. They are not wrong, but I wanted to share why I bought a vinyl without a record player. I own four vinyl records. I’ve never played a single one in my house, and I’m not planning to buy a record player.

Following my adventures (part 1, part 2) with the RP2350-USB-A, I took another look at the alternatives. Specifically, I am looking for a cheap dev board with two full USB ports (1 device, 1 host), that could be easily programmable, and would be production-ready for hobbyist projects (if you’re a professional, you’ll just manufacture your […] The post (No) alternatives to the RP2350-USB-A appeared first on Quentin Santos .

In response to the GPG.Fail attacks, a Hacker News user made this claim about the 64-bit “Long Key IDs” used by OpenPGP and GnuPG, while responding to an answer I gave to someone else’s question: OK, to be clear, I am specifically contending that a key fingerprint does not include collisions. My proof is empirical, that no […]

You may have heard about a recent security vulnerability in MongoDB (MongoBleed). The gist is that you can (as an unauthenticated user) remotely read the contents of MongoDB’s memory (including things like secrets, document data, and PII). You can read the details about the actual technical issue in the link above. The root cause of the problem is that the authentication process for MongoDB uses MongoDB’s own code. That sounds like a ver....

Just released threadsafe_datastore, a simple, convenient thread-safe data store for Python. I kept rebuilding this feature to pass around context within AI agents working on the same data across multiple threads. I kept wanting a simple atomic datastore that was convenient to work with. I originally built it for arkaine | git |. So - here it is as a stand alone package for easier use. I also improved context management for real easy multi-s..

What a difference a year makes. When Netflix secured WWE Raw, a three-hour weekly live broadcast with more than three decades of history, it marked a turning point. Raw is chaos in motion: fan-fueled, unpredictable, impossible to rehearse. And now Netflix has to make it flawless. More than a licensing play. It’s an engineering gauntlet. Pulling it off means delivering a resilient platform that can handle global, live-grade performanc....

Writing forces clarity. When I explain a concept to others - in a doc, a talk, a code review comment, even just chatting with AI - I discover the gaps in my own understanding. The act of making something legible to someone else makes it more legible to me. – Addy Osmani in 21 Lessons From 14 Years at Google The one quoted above is #12, and I’ve been religiously abiding by it for a long time, but all 21 are well worth reading.

Someone asked me which contra dance bands and callers played the most major gigs in 2025, which reminded me that I hadn't put out my annual post yet!

New events included Chain Reaction (Maine dance weekend), Galhala (women's dance weeken....

Why write? In this age of algorithmically curated feeds and LLM generated slop, the question is more vital than ever, but vital answers are short in supply. There are doubtless some who will argue that due to the pure volume of writing (or at least “writing”) that is currently being churned out, the actual value of another piece is close to zero; perhaps they would say that the marginal utility approaches zero, to justify their philisti....

I recently ported the Hardcaml_step_testbench library , one of the libraries that we use at Jane Street for Hardcaml simulations, from using monads to using algebraic effects, a new OCaml 5 feature. This blog post walks through what algebraic effects are, why you should consider using them in lieu of monads, and how to actually work with them using the Handled_effect library . One thing I’ve come to believe is that most of what can be don..

Back in October 2024, I got my hands on a Snapdragon Dev Kit . With a Qualcomm Snapdragon X Elite ARM64 CPU (the fastest model!), 32GB of RAM, and a 512GB SSD, it ran Windows 11 for ARM lightning fast. So I made it my daily driver, and it stayed that way until very recently. I even wrote a review of it one year later back in October.
