Large-scale distributed software systems are composed of several individual sub-systems—such as CDNs, load balancers, and databases—and their interactions. These interactions sometimes have unpredictable outcomes caused by unforeseen turbulent events (for example, a network failure). These events can lead to…
We rewrote critical software that powers all online storefronts on Shopify, offering the fastest online shopping experience, entirely from scratch and without downtime.
Examining the extent of AVX related downclocking on Intel’s Ice Lake CPU
A talk on OpenBSD for beginners
ARM traditionally uses compressed kernels. This is done for two major reasons: It saves space on the flash memory or other storage media...
Today, I wanted to see if I could out-compile my C compiler. I added a hand-compiled assembly version of echo from our previous coding exercise and added a new make target, make asm , that will assemble it. Let's look at our hand-compiled assembly and compare it to our C compiler and ask whether or not it was worth it.
Welcome Redditors and HackerNews folks! This post is getting attention outside the QEMU community, so I'd like to highlight two things that...
I built a 28-core gigabit cluster, Kraken, consisting of 7 Raspberry Pi 3 Model Bs.
Ways of dealing with the fractured address space.
Why buy an expensive desktop computer when your iPhone is a faster SMT solver?
Continuing on from our tiny snake game , let's explore more into how binaries work on Unix. Let's figure out how our programs come to obtain their argc and argv parameters.

Discussions of coroutines and user-mode threads — like Project Loom's virtual threads or Go's goroutines — frequently turn to the subject of performance. The question I'll try answering here is, how do user-mode threads offer better application performance than OS threads?
In Prague, the C++ committee took a series of polls on whether to break ABI, and decided not to. There was no applause. But I’m not sure we fully understood what we did and the consequences it could have.
This guide describes how to tune your AMD64/x86_64 hardware and Linux system for running real-time or low latency workloads.
I was looking at one of my classic Macs a few weeks ago, and noticed that my Ubuntu 18.04 netatalk server wasn’t showing up in the Chooser anymore. If you’re not familiar with netatalk , it’s an implementation of Apple Filing Protocol (AFP) that runs on Unix-like operating systems such as Linux and NetBSD. It allows…
A few years ago I splurged on an exercise bike. It’s a pretty expensive item imho, both in upfront and ongoing subscription costs. But I was able to justify it by riding it all the time so that per-ride it wasn’t that expensive. I’m happy to say this was a huge boon for my fitness and it was worth every penny.
A common situation in asyncio Python programs is asynchronous initialization. Some resource must be initialized exactly once before it can be used, but the initialization itself is asynchronous — such as an asyncpg database. Let’s talk about a couple of solutions.
Documentation and guides from the team at Fly.io.
Initially, I wasn’t sure whether to write about this migration project, but when I randomly asked if people would be interested, the response was overwhelming. This was a long, kind of boring, very repetitive, and at times incredibly frustrating project, but I learned a lot, and maybe someone else will learn from this…
Cloudflare is a security company, and the heart of Workers is, in my view, a security project. Running code written by third parties is always a scary proposition, and the primary concern of the Workers team is to make that safe.
This post is all about speculative compilation, or just speculation for short, in the context of the JavaScriptCore virtual machine.
Benchmarks & Tips for Big Data, Hadoop, AWS, Google Cloud, PostgreSQL, Spark, Python & More...
The software ecosystem has a lot of useful but unsafe code, and the easier it is to sandbox that code, the moreoften that’ll happen. If it were as simple as ...
A file system is responsible for organising and providing an abstraction over the storage devices where the data is physically stored. In this post, we will learn more about the concepts used by file systems, and how they fit together when writing your own.
