My day job is in browsers and cryptography , not compilers, yet I often find that I need to spend more of my time working through the semantics of programming languages than using them. This post discusses a thorny cross-language issue between C, C++, and Rust. In short:
UPDATE: This blog post has been updated based on feedback from Reddit and Hacker News. HN discussion: https://news.ycombinator.com/item?id...
We revise some fundamental background and highlight an important concern behind Java 21 virtual threads: deadlocks might be unpredictable
[English]These are currently difficult times for customers and resellers of VMware products who want to reorder, extend licenses or simply activate product licenses. After the Broadcom takeover…
Apple’s M2 chip uses a newer version of the CPU core instruction set. This increases its capability, thus how well it will cope with future apps and macOS, compared with the M1.
"Wal2" mode is very similar to "wal" mode. To change a database to wal2 mode, use the command:
From Hypervisor APIs in OS X 10.10 Yosemite in 2014, through early VirtIO kernel extensions in Mojave in 2018, and Arm hypervisor support in Big Sur.
Guide to PostgreSQL Replication and CDC - Navigate the complexities of logical replication in PostgreSQL.
This is the Part 2 of a series. Feel free to read the prequel for more context: Building the fastest Lua interpreter automatically Building a good VM for a dynamic language takes a ton of engineerin
Linux's epoll API solved the C10K problem, enabling fast and afforable Internet services.
A Rust object that survives program restart thanks to Rust allocators, systemd's file descriptor store, and syscall memfd_create.
I was explaining on Hacker News why Windows fell behind Linux in terms of operating system kernel performance and innovation. And out of nowhere an anonymous...
This post is not going to be about what’s wrong with individual databases. There are so many databases and so many individual API issues, operational problems, and arbitrary limitations that it wou…
We estimate the magnitude of speed improvement for optimization solvers and computer hardware in the 35 years from 1989 to 2024.
What does ext4 look like?
Welcome back to FOSS Fridays! This week, I’m covering a real pickle. I’m acutely aware of the flames this blog post will inspire, but I feel it is important to write nevertheless. I volunteer my ti…
M3 chips widen the gap between Pro and Max variants. They also change relative performance between P and E cores to make M3 CPUs more versatile.
Why do I do this to myself? I have no idea. Anyway, let's learn how to eat disk space.
Upgrade CentOS and Red Hat Enterprise Linux 7 to supported systems with Red Hat's in-place solutions
In this blog post, you will learn different methods to harden your OpenBSD system, and in which situation they are useful
Maestro is a Unix-like kernel and operating system written from scratch in Rust
If you've ever used the GNU Compiler Collection (GCC) then you've worked with the gcc binary. For those who don't know, gcc is a driver, not a compiler. It runs the compiler/assembler/linker as required and coordinates the input and output between them. Use of the driver is so ubiquitous that everyone calls it the…
SIEVE is Simpler than LRU: an Efficient Turn-Key Eviction Algorithm for Web Caches
This post is about the AioContext lock removal in QEMU 9.0 (planned for release in 2024), how we got here, and what it means for multi-threa...
I recently found that MAME supports running the SGI Indy while looking for ways to test some modifications I was making to the mips code in 9front. After a fair bit of elbow grease cinap and I (but mostly cinap) were able to get the old 9front indy kernel booting and running within mame. I thought I might as well…
Let's blink an LED on Pine64 Ox64 BL808 64-bit RISC-V Single-Board Computer... With Nim Programming Language and Apache NuttX Real-Time Operating System
