I’m a huge fan of interactive programming (see: JavaScript , Java , Lisp , Clojure ). That is, modifying and extending a program while it’s running. For certain kinds of non-batch applications, it takes much of the tedium out of testing and tweaking during development. Until last week I didn’t know how to apply…
Prompt is a terminal that marries the best of GNOME Builder’s seamless container support, the beauty of GNOME Text Editor, and the robustness of VTE. I like to think of it as a companion terminal to Builder. Though it's also useful for immutable/container-oriented desktops like Fedora Silverblue or Project Bluefin…
Designing far memory data structures: think outside the box Aguilera et al., HotOS’19 Last time out we looked at some of the trade-offs between RInKs and LInKs, and the advantages of local in…
Yesterday, I discovered an experimental Big Data processing framework written in C++ called Thrill. As most of you surely know, the well-known frameworks of this kind are mostly based on JVM, like …
The new Swift 5.9 release contains a number of helpful, new features for debugging code, including an out-of-process, interactive crash handler to inspect crashes in real time, the ability to trigger the debugger for just-in-time debugging, along with concurrency-aware backtracing to make it easier to understand…
Ever since the demise of Google+, many developers have expressed a desire to have a service that would provide a way to create and manage...
Updated March 13, 2012 at 10:43PM: I have a list of limitations and known bugs toward the end. Updated March 14, 2012 at 9:30PM: I’ll be on the VMware Community Roundtable podcast at 12:00PM …
Let's explore and deobfuscate the input stack on Linux. Our aim is to understand its components and what each does. Input handling can be divided into two parts, separated by a common layer. We’ll try to make sense of all this, one thing at a time, with a logical and coherent approach.
I started working on Flyaway with the intention of becoming familiar with Wayland, its protocols and extensions, and the wlroots library. Instead, I ended up genuinely liking all three.
We are archiving Atom and all projects under the Atom organization for an official sunset on December 15, 2022.
Binarly uncovers CVE-2025-3052: a Secure Boot bypass affecting most UEFI devices, enabling attackers to run unsigned code before OS load.
Part of my series on countering misconceptions in space journalism. The SpaceX Starship is a game changer for space exploration. It is intended to be far bigger, cheaper, versatile, and available t…
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…
How many problem domains require wrapping signed integers or non-wrapping unsigned integers? Can the current undefined case be replaced with a trap and everything else be left intact?
I’ve always wanted an ARM server in my homelab. But earlier, I either had to use an underpowered ARM system, or use Asahi which not only requires expensive Mac hardware but also slowed down in the past few years.
Examining the extent of AVX related downclocking on Intel’s Ice Lake CPU
When a service fails to start up enough times in a row, systemd gives up on it. On servers, this isn’t what I want — in general it’s helpful for automated recovery if daemons are restarted indefinitely. As long as you don’t have circular dependencies between services, all your services will eventually come up after…
Cassandra is a highly-available, linearly-scalable data store, but would it work for the Parse.ly team? Read on for how to avoid common pitfalls when working with this tech!
To @AndrewHart: “Our app is shit and we know it’s shit”. My life changed forever when a senior exec from one of the world’s largest retailers messaged me on Twitter. This was back in 2017. My outdoor AR navigation demos had just gone viral, and my new open-source project for...
This is probably the question I get asked most about Spacetime. It’s a simple enough question, and it certainly seems like it should have a simple answer. Scaling is a complex topic, and the devil is…
Suppose you’re a savvy C++ developer who knows all about data-oriented design and the importance of optimizing for cache locality if you want a prayer of running fast on modern hardware. Now suppose you want to go beyond basics—”just use std::vector ” is a good starting point, but you want more!
