Heads-up: An update to this article has been posted. There have been a lot of complaints about both the competency and the logic behind the latest Epstein archive release by the DoJ: from censoring…
Instant Linux microVMs with defense-in-depth security for running untrusted code.
A compressed 8KB docs index in AGENTS.md achieved 100% on Next.js 16 API evals. Skills maxed at 79%. Here's what we learned and how to set it up.
Since launching Skip in 2023, we’ve pursued one mission: enable developers to create premium mobile apps for iOS and Android from a single Swift and SwiftUI codebase — without any of the compromises that have encumbered cross-platform development tools since, well, forever.
Brave has overhauled its Rust-based adblock engine to reduce memory consumption by 75%, bringing better battery life and smoother multitasking to all users.
How do you review code at the volume agents produce it? On the Claude Code team, once we had high coverage and deep reviews, we started optimizing for the minimum amount of human review time that doesn't raise reverts or incidents.
Cloudflare's global network is immense but not limitless. As we look for small ways to trim our resource usage, we sometimes get lucky and we can cut significantly more. Here’s how we reduced one of our Pingora-based service's RAM usage with statistics.
Use Codex anywhere with the ChatGPT mobile app. Monitor, steer, and approve coding tasks in real time across devices and remote environments.
Our next npm major version, v12, introduces security-related default changes to npm install. All these changes are available behind warnings in npm today on 11.16.0 or newer, so you can…
A randomized trial with 52 developers found AI assistance lowered comprehension scores, except when used for explanations rather than delegation.
Out of all the migrations I help teams with, Go to Rust is a bit of an outlier. It’s not a question of “is Rust faster?” or “does Rust have types?”, Go already gets you most of the way there. The discussion is mostly about correctness guarantees, run…
Claude formally proved security properties in the compiled code of 123 open-source libraries. Along the way, it found bugs that had eluded detection for years.
The release Python Polars 2.0, bringing the streaming engine, out-of-core and first class blazingly fast SQL support
Every language pitches async/await as synchronous-looking code, and the same two keywords appear everywhere. But behind the shared syntax hide nine independent design decisions, and no two of seven modern runtimes agree on what even the simplest async programs should do! In this paper we map the design space of…
Temporal is the Date system we always wanted in JavaScript. It's extremely close to being available so Mat Marquis thought it would be a good idea to explain exactly what is better about this new JavaScript date system.
We removed over 80% of Claude Code's system prompt for more advanced models. How to apply the lessons we learned to your own context engineering in Claude Code and with your own agents.
The DuckDB team is happy to announce that today we're releasing DuckDB version 2.0.0 LTS, codenamed “Cinnamon Teal” (Spatula cyanoptera). This is our biggest feature release so far, and it ships a polished version of the Quack protocol, asynchronous I/O, a first-class VARIANT type, agent mode, triggers, an extensible…
One of the simplest tests you can run on a database:
A technical deep dive into the Codex agent loop, explaining how Codex CLI orchestrates models, tools, prompts, and performance using the Responses API.
A seven-month-old arbitrary code execution vulnerability remains present in Cursor, leaving 1 million daily users to rely on public disclosure after months of unsuccessful attempts to obtain remediation updates.
Introducing ggsql, a grammar of graphics for SQL that lets you describe visualizations directly inside SQL queries.
Today we’re introducing SWE-2, our most advanced coding model yet. SWE-2 delivers highly competitive agentic coding performance across multiple effort…
The Web streams API has become ubiquitous in JavaScript runtimes but was designed for a different era. Here's what a modern streaming API could (should?) look like.
During the rapid technological advancements of the early 1990s, the video game industry was on the cusp of a massive addition - another dimension. With console shenanigans like the Super FX chip giving players a taste of 3D, hype was at an all-time high. But the games released for home consoles were nothing compared…
I've previously explained async bloat and some work-arounds for it, but would much prefer to solve the issue at the root, in the compiler. I've submitted a Project Goal, and am looking for help to fund the effort.
As AI shifts software engineering from writing to reviewing, discover how Go's strict compiler and unified toolchain ensure reliable AI-generated code.
The full Claude Code transcript from discovering and responding to the litellm 1.82.8 PyPI supply chain attack on March 24, 2026 — from mysterious process explosions to malware identification to public disclosure.
Cloudflare is collaborating on tsrs, a Rust port of TypeScript that is up to 8x faster and uses 70% less memory.
What it takes to run 2 million lines of Haskell in production at a fintech company serving 300,000 businesses.
Vim 9.2 brings significant enhancements to the Vim9 scripting language, improved diff mode, comprehensive completion features, and platform-specific improvements including experimental Wayland support.
