This PEP provides the motivation and rationale for PEP 634 (“Structural Pattern Matching: Specification”). First-time readers are encouraged to start with PEP 636, which provides a gentler introduction to the concepts, syntax and semantics of patterns.
The Zig community is decentralized. Anyone is free to start and maintain their own community , which is not subject to these rules.
This is a guest blog post written by Andrew Brown , with help from the PyPy developers on the pypy-dev mailing list. This tutorial's master...
Explore how Materialize engineers diagnosed and resolved a rare concurrency bug in Rust's unbounded channels that led to undefined behavior through double-free memory errors.
Practical guidance from Anthropic on building reliable AI agents, from simple composable patterns to fully autonomous systems.
It’s funny - I have shared this story a handful of times with friends of mine who are qualified, competent software engineers, and each time the response was confusion about why any of this would be necessary or even remotely helpful. WebAssembly ?!
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 our first release in 2002, there have been 69 security bugs in Firefox’s style component. If we'd had a time machine and could have written this component in Rust from the start, 51% wouldn't have happened. That said, Rust is not foolproof. Developers still need to be aware of correctness bugs and data leakage…
Go team plans around error handling support
Lin Clark introduces the Bytecode Alliance, and uses Code Cartoon illustrations to share their vision of a WebAssembly ecosystem that is secure by default, fixing cracks in today’s software foundations. ...
Pyodide is an experimental project from Mozilla to create a full Python data science stack that runs entirely in the browser. We think it’s worthwhile to work on moving the ...
Why your JavaScript events are coming in quicker now.
A delightful language with friendly error messages, great performance, small assets, and no runtime exceptions.
A substantial improvement in intelligence and behavior over Composer 2, particularly on long-horizon agentic tasks.
Welcome to this tutorial series on ARM assembly basics. This is the preparation for the followup tutorial series on ARM exploit development . Before we can dive into creating ARM shellcode and build ROP chains, we need to cover some ARM Assembly basics first.
Since we originally proposed the need for a first-class language, compiler and ecosystem for machine learning (ML), there have been plenty of interesting developments in the field. Not only have the tradeoffs in existing systems, such as TensorFlow and PyTo...
``Frequently'' means thou shouldst draw thy daily guidance from it, rather than hoping thy code will achieve lint's blessing by a sudden act of repentance at the last minute. De-linting a program which has never been linted before is often a cleaning of the stables such as thou wouldst not wish on thy worst enemies…
.NET 7 is fast. Really fast. This post deep-dives into hundreds of performance improvements that contributed to that reality.
Jonan: Welcome everyone. Today we are doing an interview to talk about new features coming in Ruby 3. I am here with my coworker, Sasada Koichi san....
February 9, 2021: Post updated with the current regional availability of container image support for AWS Lambda. With AWS Lambda, you upload your code and run it without thinking about servers. Many customers enjoy the way this works, but if you’ve invested in container tooling for your development workflows, it’s not…
A detailed look at how we replaced the most performance-sensitive portions of the source-map JavaScript Library’s source map parser with Rust code that is compiled to WebAssembly. The results: The ...
Go is a simple and fun language, but, like any other language, it has a few gotchas... Many of those gotchas are not entirely Go's fault. Some of these mistakes are natural traps if you are coming from another language....
Just as algebra is fundamental to the whole of mathematics, algebraic data types (ADTs) are fundamental to many common functional programming languages. They’re the primitives upon which all of our richer data structures are built, including everything from sets, maps, and queues, to bloom filters and neural networks .
YJIT’s ability to improve performance by adapting to run-time behavior can increase the speed of our code in a way that dropping down to C can’t. As such, I think we should reconsider the common wisdom that “rewriting our Ruby in C” is the ideal path to performance optimization and take a serious look at “rewriting…
Posted by Joshua Bloch, Software EngineerI remember vividly Jon Bentley's first Algorithms lecture at CMU, where he asked all of us incoming Ph.D. ...
