I have spent a large portion of my career working in Java. In that time, you get used to huge classes. New functionality? Just add a new method and field to the class. The cost of each new field is rarely considered. Performance is often considered from a classic computer science perspective by considering asymptotic…
On the 31st August I got an email from a customer, telling me that they had found an imitation of my data wrangling software on Github. I’m not linking to it, but here is a screenshot: It is …
One of the most fascinating things I’ve learned about recently is the engineering behind the US Strategic Petroleum Reserve. Here are the key requirements it’s designed to meet: Store …
FFmpeg is truly a multi-tool for media processing. As an industry-standard tool it supports a wide variety of audio and video codecs and container formats. It can also orchestrate complex chains of…

Starting with v2.0, scheduled for fall 2026, DuckDB will support asynchronous reads of Parquet and CSV files. This can significantly speed up queries when synchronous I/O does not saturate the available bandwidth, as is typical in EC2/S3 compute-storage setups.
Passkeys are the future of authentication, but using them for data encryption is a disaster waiting to happen. Overloading these credentials creates a dangerous blast radius that can lead to the irreversible loss of a user's most sacred memories and documents.

Latest Geekbench performance figures for macOS VMs, and testing of how few cores and how little memory is really needed: could you run a macOS VM usefully on a MacBook Neo?
Deep learning has been built around backprop, the only credit assignment algorithm capable of training modern neural nets, including transformer-based language models. Backprop requires differentiability and produces first-order gradients, and deep learning’s architectures, optimizers, and hardware have co-evolved…
Ever since Golden Gate Claude I’ve been fascinated with “steering”: the idea that you can guide LLM outputs by directly manipulating the activations of the…
Back in 2019, SwiftUI was announced as the future of Apple development. Seven years later, it still feels like a beta version struggling with stability, performance, and many other aspects. What’s actually wrong with SwiftUI?
I had a friend tell me recently that all programming languages seem very similar to each other. They all have variables, and arrays, a few loop constructs, functions, and some arithmetic constructs. Sure, some languages have fancier features like first-class functions or coroutines, but he doesn't consider himself an…
If xAI defaults on its debt, Apollo Global Management ends up in the GPU rental business.
This past Tuesday I typed C-x C-c in Emacs for the last time after 20 years of daily use. Though nearly half that time was gradually retiring it, switching to modal editing, then to Vim. Emacs is a platform, and I’d grown accustomed to its applications, especially those I built myself. There was no particular hurry…

We’re happy to announce a new release of ClojureScript. If you’re an existing user of ClojureScript please read over the following release notes carefully.
Many of us are inconsistent in our economic desires. I would like the price of my home to rise, because it increases my wealth, but I would also like the prices of all other homes to fall, so that I could sell my house and buy an even nicer house. Also, I would like to
