This blog site has been archived. Go to react.dev/blog to see the recent posts. Today, we are publishing the first Release Candidate for React 17. It has been two and a half years since the previous major release of React, which is a long time even by our standards! In this blog post, we will describe the role of this…
An appropriately annoying strategy for dealing with wiki rot at a company.
Short answer: because we said so.
I am planning to create a series of blog posts that includes some literature research, implementation of various data structures and our journey of creating a distributed datastore in distrentic.io.
Why buy an expensive desktop computer when your iPhone is a faster SMT solver?
Continuing on from our tiny snake game , let's explore more into how binaries work on Unix. Let's figure out how our programs come to obtain their argc and argv parameters.
So far everything we’ve done with breakpoints involved us creating a breakpoint file and using this to automate part of a track. Now we’ll take a look at how we can take an existing track and extract some breakpoints from this. For this post, we’ll take a look at extracting the amplitudes from the .wave files, as this…
If you read a description of a static analysis in a paper, what might you find? There’ll be some cute model of a language. Maybe some inference rules describing the analysis itself, but those rules probably rely on a variety of helper functions. These days, the analysis likely involves some logical reasoning: about…
Today, we are sharing details about Pysa, an open source static analysis tool we’ve built to detect and prevent security and privacy issues in Python code. Last year, we shared how we built Zoncola…

Discussions of coroutines and user-mode threads — like Project Loom's virtual threads or Go's goroutines — frequently turn to the subject of performance. The question I'll try answering here is, how do user-mode threads offer better application performance than OS threads?
I've been wanting to write a big project in Rust for a while as a learning exercise, and actually started one in late 2018 (a FUSE server implementation). But then life happened and I got busy and never went anywhere with it. Due to certain world circumstances I'm currently spending a lot of time indoors so rust-fuse…
Django is currently the most commonly used full-stack web framework for Python. It has been around for a good 15 years, emerging as a winner from a period in which Python was already mature, but its web development tools were comparatively much more immature and fragmented.
Perhaps the most interesting part of the open RISC-V instruction set architecture (ISA) is the vector extension (RISC-V "V"). In contrast to the average single-instruction multipe-data (SIMD) instruction set, RISC-V vector instructions are vector length agnostic (VLA). Thus, a RISC-V "V" CPU is flexible in choosing a…
Over the last year, my 13 year old nephew developed a love for hacking. From anime chat , to snake , a minimal twitter , a blog , to an anime music startup , he’s built some cool stuff (1). What I’m most proud of though, is that he’s done this with self directed play, rather than with a rigid curriculum.
I last wrote in April about my work on speeding up the Rust compiler. Time for another update.
Dropbox syncs petabytes of data every day across millions of desktop clients. It is vital that we constantly improve the sync experience for our users, to increase our users’ productivity in their everyday lives. We also constantly strive to better leverage our infrastructure, increasing Dropbox’s operational…
Full-Text Search is one of those tools people use every day without realizing it. If you ever googled "golang coverage report" or tried to find "indoor wireless camera" on an e-commerce website, you used some kind of full-text search.
Let’s start the week with Lambda Expressions. The plan is to have a set of concise articles presenting core elements of lambda expressions. Today you can see how the syntax has evolved starting since C++11 and what are the latest changes in C++20. The Series This blog post is a part of the series on lambdas:
I’m pleased to announce the availability of the first release of SIMD Everywhere (SIMDe), version 0.5.0, representing more than three years of work by over a dozen developers.
