GPU code can now use Rust's standard library. We share the implementation approach and what this unlocks for GPU programming.
A technical deep dive into the Codex agent loop, explaining how Codex CLI orchestrates models, tools, prompts, and performance using the Responses API.
We're excited to announce the release of pandas 3.0.0. This major long-awaited release brings significant improvements to pandas, but also features some potentially breaking changes.
Forking pg_query.rs to replace Protobuf with bindgen-generated direct C-to-Rust struct mappings, yielding 5x faster query parsing and 10x faster deparsing in PgDog.
There are many interesting, useful, and fun C libraries in the software ecosystem. While one could go and rewrite these libraries in Swift, usually there is no need, because Swift provides direct interoperability with C. With a little setup, you can directly use existing C libraries from your Swift code.
Jamf Threat Labs uncovers North Korean hackers exploiting VS Code to deploy backdoor malware via malicious Git repositories in the Contagious Interview campaign
Lix is a version control system you import as a library. It records semantic changes to enable diffs, reviews, rollback, and querying of edits.
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.
Exploring alternatives to the archived_at column pattern: triggers, application events, and WAL-based change data capture.
An in-depth exploration of maintenance, and a powerful argument for its civilizational importance.
Who is the Assistant? We investigate the character that most modern language models inhabit when interacting with users.
A high-performance and high-level purely functional data-parallel array programming language that can execute on the GPU and CPU.
jQuery: The Write Less, Do More, JavaScript Library
A proposal for a standard /install.md file that provides LLM-executable installation instructions.
A practical handbook for developers using LLMs to get structured outputs.
So that we may educate as well as horrify: the internals of our new Sprites execution platform.
We've been experimenting with running coding agents autonomously for weeks at a time.
Some numbers about the evolution of the Servo project and its community during the last years.
Rails 8 eliminates Redis from the default stack. Learn how SolidQueue, SolidCache, and SolidCable replace Redis for job processing, caching, and real-time updates—powered entirely by PostgreSQL. Explore the true cost of Redis, how SolidQueue works, when it scales, and how to migrate from Sidekiq to a simpler…
Discover the new way to request user location data.
How a 40-line OpenJDK fix swapped slow /proc parsing for a single clock_gettime syscall, closing a 400x thread CPU-time gap hidden for 20 years.
We get asked about AI a lot. Whether we’re going to add it to Yarn Spinner, whether we use it ourselves, what we think about it. Fair questions. Time to write it all down. Yarn Spinner doesn’t use the technology that’s currently being called AI. We don’t have generative AI features in the product, and we don’t use…
How I reverse-engineered GitHub node IDs to avoid a database migration and discovered their dual ID system along the way.
This guide explains message queues with analogies: databases, warehouses and post offices.
The craft of engineering is rapidly changing. We built our own coding agent to accelerate faster. Inspect is now open to teams outside Ramp through early access.
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 replaced LibDOM with a custom Zig implementation for better cohesion across events, Custom Elements, and ShadowDOM. Here's how we built it and what we learned along the way.
