In the ELF format there are two ways of providing a hash table of symbols. DT_HASH and DT_GNU_HASH . The first one is part of SYSV generic ABI and is well documented and marked as mandatory. DT_GNU_HASH is a newer, smaller, and faster replacement that is not documented , implemented in a few places (Glibc, GNU ld…
tl;dr: Having swap is a reasonably important part of a well functioning system. Without it, sane memory management becomes harder to achieve.
Making performant dynamic manual memory management in C feel almost like garbage collection.
Rosetta 2 is remarkably fast when compared to other x86-on-ARM emulators. I’ve spent a little time looking at how it works, out of idle curiosity, and found it to be quite unusual, so I figur…
In this blogpost I argue why it's strongly recommended to use ZFS with ECC memory when building a NAS. I would argue that if you do not use ECC memory, it's reasonable to also forgo on ZFS altogether and use any (legacy) file system that suits your needs.
After a year in development, the open source “Asahi” driver for the Apple GPU is running real games. There’s more to do, but Neverball is already playable (and a lot of fun!).

This post describes the implementation and use of pledge() and unveil() in SerenityOS.
Dmitry.GR: My business card runs Linux (and Ultrix), yours can too. Details, kits, etc...
How would you build an operating system? My answer is I wouldn't. First off, I don't know how. And the second thing is it seems like to large of a task. It took thousands of developers to build Windows XP. But actually, it is possible to build an operating system from scratch. My guest is doing it. Andreas Kling…
I unlocked Hypervisor.framework on my jailbroken phone and modified UTM, a popular QEMU port for iOS, to run arm64 Linux in a VM at full native speed. …for the clickbait - and to show iPhone’s untapped potential.
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
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…
Have you ever wondered about the performance delta between Caddy and Nginx? Wonder no more.
so here's a short tutorial on ansi escape codes and terminal control, because you philistines won't stop using ncurses and oh my god WHY ARE WE STILL USING NCURSES IT IS THE TWENTY FIRST FUCKING CENTURY
I talked at the first Zig meetup in Milan about Uber's early experience with Zig: a little about how Uber uses Zig and more about my experience of bringing Zig to Uber, from both technical and social aspects.
File synchronization can be fun and painless if you don’t have to deal with corporate bullshit.
I continue to have no time for big programming projects, so here is a short blog post. Two years ago I looked into a bug in the glibc implementation of condition variables: Sometimes pthread_cond_s…
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!
