An opposite view on .gitignore files.
Two years of nightmarish smiles and makeup before anyone laid hands on Mimic Systems' actual product.
AI-assisted incident response can lower MTTR while leaving engineers less prepared for the complex incidents automation cannot solve.
We are accelerating elements of our upcoming v5 release with interim updates to keep pace with the frontier. Index v4.2 has more complex and realistic tasks, and more private test sets to prevent gaming
Most of what an AI coding agent does for me isn't thinking. It's I/O.
Video on Twitch and YouTube, CSS scroll snap, JavaScript debugging, session restore, and a serious push on engine performance with a new style engine.
I’m sure that some pictures are worth a thousand words, but others trigger a whole lot of puzzlement. Such was the case with the cover of a book I recently bought entitled Calculating with Tones: The Logarithmic Logic of Music:
Perceptions of government corruption in the U.S. hit a record high in 2026, with broad agreement across partisan lines.
An international team including Oxford physicists has observed a long-predicted effect of gravity on a falling quantum object for the first time. The study provides an experimental connection between quantum physics and Einstein's theory of gravity.
A look at what current models can build, where they fail, and how EEBench tests the electronics in simulation.
Rietta patched a government client's Ruby on Rails site within hours of a 9.5 CVSS ActiveStorage CVE. Exploit attempts began before business hours resumed.
Mullvad has operated public encrypted DNS (DoH) servers since 2022. They are unnecessary when using Mullvad VPN — traffic is already encrypted and Mullvad VPN's internal DNS handles all queries.
Anthropic is an AI safety and research company that's working to build reliable, interpretable, and steerable AI systems.
The transition to the Rust version of the React Compiler for the 1,036-file React Router codebase resulted in a significant speed increase, improving build times from 14.3 seconds to 0.81 seconds. The new compiler addresses previous limitations and ensures consistency across the toolchain, making it easier to manage…
While I’m taking a short break from low-level programming, here’s a story by a friend of mine, Sonya, about debugging a seemingly impossible bug in ARM code. This bug hunting saga started several months ago. While developing a bare-metal hypervisor on ARM64 for postmarketOS, I hit a strange bug: if I enabled the…
This is probably the question I get asked most about Spacetime. It’s a simple enough question, and it certainly seems like it should have a simple answer. Scaling is a complex topic, and the devil is…
A US and UK data study: when the same product ranks in both Google AI Mode and traditional search, the AI Mode price is about 21.6% higher.
Or: Why do I always do things the hard way?
reenigne's decoding of the 8088 microcode in 2020 opened the doors for extremely accurate emulation of the 8088 CPU. Although I had added...
Retrospective on Project Xanadu’s success and failure: a lack of design iteration, meaningful use-cases, or practicality stopped a valuable vision from maturing into something useful. (And contrasted with my approach.)
small programs hide coupling
We watched almost 17k sessions across different types of personas, with 1,163 prompt variations, 75 repositories and 3 coding agents (Claude Code, Codex, Cursor) actually implementing the solutions instead of just recommending one.
OpenAI's GPT-6 Astra reaches state-of-the-art results on ARC-AGI-3
A lot of the educators I admire in the frontend web space seem to be either bowing out or dialing back their efforts: Axel Rauschmayer, Salma Alam-Naylor, Josh…
Introducing GPT-6 Astra, our most intelligent and aligned model yet, with state-of-the-art capabilities across computer use, coding, cybersecurity, and science.
Starting 2027, Google will block apps on Android devices whose developers have not registered with Google, paid, and given their ID. It’s fair to say that Google is becoming Apple: Your device, their rules.
