This talk will reflect on what GNU Guix has to offer to users and how it compares to other approaches—from CONDA and pip to Flatpak and Docker. Guix is not only a transactional package manager and declarative GNU/Linux distribution: it’s also an environment manager, a container provisioning tool, and more. We will…
In order to support its growing ecosystem and community as we move toward the 3.0 release, we are making changes to Vagrant that will maintain its Ruby-based features while being ported to Go.
The goal is to connect a non-WiFi computer to a WiFi network using a Raspberry Pi. We will use a Raspberry Pi 4 Model B as a bridge between the non-WiFi computer and the WiFi network. The Raspberry Pi connects to WiFi and shares its connection with other computers over Ethernet. These instructions were only tested and…
Operating what you build, empowered with amazing developer tools
We experienced a global outage due to an undiscovered software bug that surfaced on June 8 when it was triggered by a valid customer configuration change. Here's a rundown of what happened, why, and what we're doing about it.

We have hundreds of jobs running in a variety of different environments. One day something very odd happened — our Jenkins UI stopped working although the…
This section lists the release notes for each stable version of NixOS and current unstable revision.
Here's a few patterns I've picked up based on using Docker since 2014. I've extracted these from doing a bunch of freelance work.
You can mount code from your development machine into a container and save yourself tedious waiting times during development.
The pressure the cloud puts on margins can start to outweigh the benefits you scale and growth slows. Understand how much market cap is being suppressed by the cloud to help inform the decision-making framework on managing infrastructure as companies scale.
Building on top of OpenTelemetry empowers us to provide integrated and opinionated observability solutions for our application engineers.
HAProxy 2.4 adds features such as support for HTTP/2 WebSockets, authorization and routing of MQTT and FIX protocol messages, DNS resolution over TCP, and more.
You're going to want to make some changes to what goes into that disk image later, but for now just build a disk image.
This post will walk you through the performance tuning steps that I took to serve 1.2 million JSON 'API' requests per second from a 4 vCPU AWS EC2 instance.
I needed a very basic 'Internet sharing' router setup with one of my Raspberry Pis, and I thought I'd document the setup process here in case I need to do it again. I should note that for more complex use cases, or where you really need to worry about security and performance, you should use something like OpenWRT…
Chia is a few months old, and we are already witnessing the impact of Chia on all our products. Speculative farmers are forcing their way in to make as much money as possible, as quickly as possible.
One of the best ways to find ways to improve performance, we’ve found, is to work closely with our customers. We love shared troubleshooting sessions with their own engineering teams to find and eliminate bottlenecks.

There are requirements that make software engineers sweat. Massive distribution to thousands of nodes. High reliability and availability. Multiple distinct platforms. Rapid network growth. This is the world SpaceX’s Starlink program, which has set a goal to provide high-speed broadband internet to locations where…
Cloudflare is uniquely positioned to become a major player in an Internet 3.0 world, where politics matter more than economics.
