Most people think assembly is only to be used to write toy programs for learning purposes, or to write a highly optimized version of a specific function inside a codebase written in a high-level language.
tl;dr: We believe there is a safer and easier way of writing a Jit. Current State Today, all browsers’ Jits share a similar design. This ...
Xe Iaso's personal website.
Imagine you wrote a program for a pleasingly parallel problem, where each thread does its own independent piece of work, and the threads don’t need to coordi...
We have a CPU mystery! We found a way to cause some processors to enter a glitch state where the normal rules don’t apply, but what does that mean…?
Teams consistently overlook speed. Instead, they add more features (which ironically make things slower). Products bloat over time and performance goes downhill.
TL;DR Modern disks are so fast that system performance bottleneck shifts to RAM access and CPU. With up to 64 cores, PCIe 4.0 and 8 memory channels, even a single-socket AMD ThreadRipper Pro workstation makes a hell of a powerful machine - if you do it right! Update 1: Since 2021, networks have gotten faster and now…
You can view a video related to this blog post here: Does UASP make the Raspberry Pi faster?. A couple weeks ago, I did some testing with my Raspberry Pi 4 and external USB SSD drives. I found a USB 3.0 SSD was ten times faster than the fastest microSD card I tested. In the comments on the video associated with that…
How does SQLite work? Part 1: pages!
Competitiveness is a vice of mine. When I heard that a friend got Linux to boot off of NFS, I had to one-up her. I had to prove that I could create...
NATS is a popular streaming system. Producers publish messages to streams , and consumers subscribe to those streams, fetching messages from them. Regular NATS streams are allowed to drop messages. However, NATS has a subsystem called JetStream , which uses the Raft consensus algorithm to replicate data among nodes…
The switch to WebAssembly increases stability, speed.
GhostLock (CVE-2026-43499) is a Linux kernel vulnerability found by Nebu that exists in every major distribution since 2011. Triggering the bug does not require any special kernel config or privilege. By turning it into a 97% stable privilege escalation and container escape, Google has rewarded us $92,337 in…
kitty is a feature-rich, cross-platform, fast, GPU based terminal. To update kitty, follow the instructions. Recent major new features: Docked windows [0.50]: kitty windows can now be docked to an ...
As much as Andy loves PostgreSQL, there is one part that is terrible and causes many headaches for people. Learn what it is and why it sucks.
In this article I will introduce a new command line search tool, ripgrep , that combines the usability of The Silver Searcher (an ack clone) with the raw performance of GNU grep. ripgrep is fast, cross platform (with binaries available for Linux, Mac and Windows) and written in Rust .
Our discovery of two privilege escalation vulnerabilities in a driver highlights the strength of Microsoft Defender ATP’s sensors. These sensors expose anomalous behavior and give SecOps personnel the intelligence and tools to investigate threats, as we did.
Porting Linux to Apple Silicon
MySQL needs little introduction. Over the last 28 years it has become one of the most widely deployed SQL databases. MySQL is primarily used for online transaction processing (OLTP) workloads, but is also deployed as a part of OLAP and queuing systems.
A look at Google's delay-controlled TCP flow control algorithm, called BBR.
I will attempt to convince you, in two lines of code, that Elixir is more interesting than any programming language you’ve ever used.
This post contains my own opinions, not the opinions of my employer or any open source groups I belong or contribute to.
Last weekend I was playing around with a way to represent null-terminated UTF8 strings in Rust. Rather than just toying with it forever, I decided ...
Online payment processing for internet businesses. Stripe is a suite of payment APIs that powers commerce for businesses of all sizes.
The idea of a zero cost abstraction is very important to certain programming languages, like Rust and C++, which intend to enable users to write programs with excellent performance profiles with relatively little effort. Since this idea is fundamental to the design of Rust and my work, I want to investigate, for a…
