What do you do when libc is your bottleneck? If the total runtime of your process is under 10ms, most of this time (depending on your hardware) is spent waiting for the linker and C runtime to set things up. If you compare this to the Latency Numbers Every Programmer Should Know , it falls right above "disk seek" and…
First release of youki, an OCI container runtime written in Rust
macOS manages the loading and frequency of M1 cores according to the QoS set, and rules which differ between the original M1 and the M1 Pro.

[German]Exchange servers (on-premises) have had woldwide a Year 2022 problem since January 1 (00:00 UTC), because mails are no longer transported due to a “date error”. Meanwhile…
Since I switched to Linux some time ago, I had my fair share of problems with running games on Linux. To be fair, most of these were not designed to run on linux, but the awesome Proton and its main project wine make it easy to run most games I am interested in seamlessly. Most of the time when problems arise, games…
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...

There's more to code than just instructions.
This article has now been extensively corrected and modified.
Spaceflight, from the beginning, has depended on computers – both on the ground and in the spacecraft. SpaceX has carried it to a new level. We recently spoke with Steven Gerding, Dragon’s software development lead, about the special challenges software development has for SpaceX's many missions.
Instructions for compiling and running MIT/GNU Scheme.
This is an excerpt from an internal document David Mackey and I co-authored in April 2019. The document is excerpted since much of the original doc was about comparing possible approaches to increasing efficency at Twitter, which is mostly information that's meaningless outside of Twitter without a large amount of…

Kestrel : A completely open computer design.
In order to get the most performant site possible when building the codebase for our public Stack Overflow site, we didn’t always follow best practices.
Earlier this year, I pitted the $549 ASUSTOR Lockerstor 4 NAS against a homebrew $350 Raspberry Pi CM4 NAS, and came to the (rather obvious) conclusion that the Lockerstor was better in almost every regard. Well, ASUSTOR introduced a new lower-cost NAS, the $329 Drivestor 4 Pro (model AS3304T—pictured above), and sent…
Docker has recently stormed into software development. While its concepts are powerful and valuable, similar tools have been used in systems for decades. FreeBSD’s jails in one of those tools which build upon even older chroot(2). To put it shortly, with these tools, you can make a safe environment separated from the…
In my last post, Qubes-lite with KVM and Wayland, I described setting up a Qubes-inspired Linux system that runs applications in virtual machines. A …
Since the Raspberry Pi Compute Module 4 was introduced last year, I've been testing a variety of PCI Express NICs with it. One of the main types of NIC I'm interested in is cheap 2.5 Gigabit Ethernet adapters. 2.5 Gigabits is about the highest reasonable bandwidth you can get through the PCI Express Gen 2.0 x1 lane on…
Last month I announced a toy project called QOI — the Quite OK Image Format . It losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression.
ReactOS is a free, opensource reimplementation of windows
A couple of weeks ago I found a really good deal on a Socket AM4 motherboard that supports the newest AMD Ryzen CPUs. The motherboard is an ASRock A520M/ac . It’s a very basic motherboard which doesn’t appear to be sold by any of the usual retailers anymore, but I couldn’t pass up on the deal, especially with the…
This week’s paper won the distinguished presentation award at HotOS 2021, and discusses the potential for future innovation in the tool that many use every day - the shell! A previous submission of this paper on Hacker News elicited a number of strong reactions. One reaction was the assertion that there are in fact…
