Now that Joel0 in the TrueNAS community has created a fork of TrueNAS that runs on Arm, I thought I'd give it a spin—on a Raspberry Pi. I currently run an Ampere Arm server in my rack with Linux and ZFS as my primary storage server, and a Raspberry Pi with four SATA SSDs and ZFS as backup replica in my studio. My…

Build resilient GitHub Actions workflows with insights from real attacks, missteps to avoid, and security tips GitHub’s docs don’t fully cover.
Today we turned off our Online Certificate Status Protocol (OCSP) service, as announced in December of last year. We stopped including OCSP URLs in our certificates more than 90 days ago, so all Let’s Encrypt certificates that contained OCSP URLs have now expired. Going forward, we will publish revocation information…
GitHub is adding a $0.002-per-minute fee on all GitHub Actions usage, so the control plane is no longer free.
An opportunity for more opinionated defaults
To prioritize the safety and security of the ecosystem, Kubernetes SIG Network and the Security Response Committee are announcing the upcoming retirement of Ingress NGINX. Best-effort maintenance will continue until March 2026. Afterward, there will be no further releases, no bugfixes, and no updates to resolve any…
Or using lots of little tools to aggressively reject the bots
The state of CI platforms is much stronger than it was just a few years ago. Overall, this is a good thing: access to powerful CI platforms enables software developers and companies to ship more reliable software more frequently, which benefits its users/customers. Centralized CI platforms like GitHub Actions, GitLab…
An exploration of how .NET evolved from a distributed build system to Unified Build, dramatically reducing complexity and build times while improving flexibility and predictability for shipping .NET releases.
Nix is a tool that takes a unique approach to package management and system configuration. Learn how to make reproducible, declarative and reliable systems.
On August 21, 2025, an influx of traffic directed toward clients hosted in AWS us-east-1 caused severe congestion on links between Cloudflare and us-east-1. In this post, we explain what the failure was, why it occurred, and what we’re doing to make sure this doesn’t happen again.

From my series of "Christian's Home Lab adventures", here's some more things I've recently learned / discovered and figured are worth sharing: NVMe SSDs on a Raspberry PI, ARM64 adventures, more zfs troubles, and some cool tools you should try.
How we saved 7 TiB of memory across our Kubernetes clusters by disabling namespace listwatching in Vector, reducing daemonset overhead and API server load at scale.
Zero-downtime deployments on Kubernetes on AWS EKS utilizing Pod Readiness Gates, graceful application shutdown and termination delays with code examples in Go
Nothing can have an unlimited uptime. But even when AWS and other hyperscalers are having incidents, we've created an architecture that is resilient to those outages. Here's how we do it for Authress.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
Read how we scaled our observability platform from 19PB to 100PB and 500 trillion rows by replacing OpenTelemetry with a native ClickHouse-to-ClickHouse pipeline, embracing wide events and cutting CPU usage by 90%.
Porffor can run on Lambda now!
Build powerful software environments and containerized operations from modular components and simple functions. Perfect for complex software delivery and AI agents. Built by the creators of Docker.
Update: January 15, 2026 Six-day and IP address certificates are now generally available. See 6-day and IP Address Certificates are Generally Available for details. This year we will continue to pursue our commitment to improving the security of the Web PKI by introducing the option to get certificates with six-day…
A guide on building a simple Linux distribution from scratch. Detailed guide on building the kernel and the init process. Finally, a little distribution is built with u-root that is capable of connecting to the Internet.

Build a Container Image from Scratch — Danish Prakash
Before we get nerd sniped by the shiny engineering details, ask the only question that matters. Why compute in orbit? Why should a watt or a flop 250 miles up be more valuable than one on the surface? What advantage justifies moving something as mundane as matrix multiplication into LEO?
Notes on installing and netbooting Windows 11 over iSCSI
An article demonstrating immutable software deployments using ZFS snapshots and FreeBSD jails, with Caddy as a health‑checked reverse proxy for zero‑downtime upgrades.
