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?
GitHub Actions has a package manager that ignores decades of supply chain security best practices: no lockfile, no integrity verification, no transitive pinning
Putting FreeBSD’s “power to serve” motto to the test. On Thanksgiving morning, I woke up to one of my web services being unavailable. All HTTP requests failed with a “503 Service unavailable” error. I logged into the console, saw a simplistic “Runtime version: Error” message, and was not able to diagnose the problem…
Microservices work best as a polytree with clear dependencies and no cycles. Learn how this structure reduces complexity and makes systems easier to scale and maintain.
Wolfram releases the Wolfram Compute Services system--a fully programmable, streamlined way to scale up Wolfram Language computations. For large volumes of data, extensive iterations, large-scale parallelism and more.
See how AWS Lambda arm64 stacks up against x86_64 in real-world benchmarks across CPU, memory, and I/O workloads using Node.js, Python, and Rust.
Experiences with the Matrix protocol, Matrix Synapse server, bridges, and Element mobile apps.
In Ukraine suicide drones strike critical infrastructure regularly. Some outages are caused directly by the attacks - destroyed power plants, substations, transformers, power lines, some are scheduled in advance - power grid wasn’t designed to work while some of its power plants and transformers are destroyed and are…
For every cloud service I use, I want to have a local copy of my data for backup purposes and independence. Unfortunately, the gphotos-sync tool stopped working in March 2025 when Google restricted the OAuth scopes, so I needed an alternative for my existing Google Photos setup. In this post, I describe how I have set…
There is a rush for AI companies to team up with space launch/satellite companies to build datacenters in space. TL;DR: It's not going to work.
An 8-bay DIY NAS with 10GbE networking, TrueNAS 25.10.0.1, an Intel N300 CPU, 32GB of DDR5 RAM, and a smallish form factor that occupies less than 20 liters of your office space.
[BROKEN LINK: blog/google-cloud-s-outage-should-not-have-happened-and-they-seem-to-be-missing-the-point-on-how-to-avoid-it-in-the-future.pre-processed.org], another global IT outage happened (dèjá vu strikes again in our industry). This time at cloudflare(Prince 2025). Again, taking down large swaths of the internet…

Compare static web hosting performance on an Intel N150 using the same nginx.conf across FreeBSD jails, SmartOS zones, NetBSD, OpenBSD and Linux, focusing on HTTP vs HTTPS and TLS CPU usage.
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…
At the time of writing 12:43 UTC on Tue 18 Nov, Cloudflare has taken many sites down. I'm trying to browse the web, but about half of the sites show an error: cloudflare.webp Most of these sites are n...
You only live once.
Everything you wanted to know about using Cloudflare Zero Trust Argo tunnels for your personal network
The Grafana Stack can be an incredible powerful monitoring solution, but through my experience I found out how maintenance intensive it is and how uncertain the…
The Minisforum MS-R1 uses the same Cix CD8180 Arm SoC as the Orion O6 I reviewed earlier this year. But everything else about this thing is different. What this thing should be, is a box that runs Linux and can compete with at least an Apple M1 Mac mini, or a mid-range Mini PC. But what we got... is something…

In distributed systems, one of the fundamental challenges is knowing whether a node or service is alive and functioning properly. Unlike monolithic applications, where everything runs in a single process, distributed systems span multiple machines, networks, and data centers. This becomes even glaring when the nodes…
Recently I've been playing around with FreeBSD in a virtual machine. The reason for this is that (if all goes well) some time in December my new Framework laptop will arrive, replacing my current X1 Carbon that is starting to show signs of old age (e.g. a keyboard where certain keys don't always work). Framework in…
For the past five months I've been leading the efforts to rebuild Zed 's cloud infrastructure.
You've been lied to. You don't need the cloud – you can just run servers and save 10x your AWS costs. It's not that difficult.
On each of the last two Fridays, Google has suspended SSLMate 's Google Cloud access without notification, having previously suspended it in 2024 without notification. But this isn't just another cautionary tale about using Google Cloud Platform; it's also a story about usable security and how Google's capriciousness…
No amount of tuning the backend service performance helped, and then I learned why. Oh no. Oh no no no no.
