We made a server-less virtual Linux environment that runs unmodified Debian binaries in the browser. This is powered by CheerpX, a WebAssembly virtualization platform. Feel free to play with it and report bugs: https://webvm.io
We assume that browser caches are near-instantaneous, but data shows that retrieving an object from cache can take hundreds of milliseconds!

When I wrote the introductory article for libjit , I aimed it at programmers who know what JITs are, at least to some extent. I did mention what a JIT is, but only very briefly. The purpose of this article is to provide a better introductory overview of JITing, with code samples that don't rely on any libraries.
Pipes are ubiquitous in Unix --- but how fast can they go on Linux? In this post we'll iteratively improve a simple pipe-writing benchmark from 3.5GiB/s to 65GiB/s, guided by Linux `perf`.
This is Part 1 of a series of posts. Part 2 is available here: Building a baseline JIT for Lua automatically It is well-known that writing a good VM for a dynamic language is never an easy job. High
In this blog we'll discuss how we manage Cloudflare IP addresses used to retrieve the data from the Internet, how our egress network design has evolved, how we optimized it for best use of available IP space and introduce our soft-anycast technology
It’s quite popular to bash the Windows Registry in non-technical or lightly technical terms. I’ve just spent a couple of weeks reverse engineering the binary format completely for our h…

So Oxide is making some cool stuff huh? Big metal boxes with lots of computer in them. Servers as they should be! Too bad I can’t afford to buy one for myself… but wait, they’re open-sourcing the software they’re writing to do it. Mom said we can have Oxide at Home!
PlanetScale offers the world’s fastest and most scalable cloud hosting for Vitess, Neki, and Postgres.
Rust prevents out-of-bounds memory accesses and buffer overruns via runtime bounds checks - what’s the cost of those bounds checks for a real-world, production application?
