Anybody who runs an internet-facing webserver has seen their fair share of spammy scanners in the logs. It varies server to server, but some of mine get up to 15,000 scans per day. Almost all of these are harmless network mappers, but they still annoy me. Many are compromised hosts or belong to hackers & organized…
A storytelling guide to starting k8s
Microsoft is increasingly standardizing on its in-house CBL-Mariner Linux distribution. Is this Microsoft Linux?

Cloudflare Pages 😍 I got into Cloudflare pages because it lets you host static websites with all the latest optimizations conveniently and for free. Setting up a static website with a custom domain is easy, and you get the benefits of automatic SSL, CDN, and latest version of HTTP3. This is how this blog is hosted and…
AWS creates a market for spot instance pricing, but this market is inefficient as customers don’t consider all instance types available. Leveraging this mispricing can save even more than spot pricing already does.
Software development still has a long way to go until it fully embraces the cloud
Basecamp has had one foot in the cloud for well over a decade, and HEY has been running there exclusively since it was launched two years ago. We've run extensively in both Amazon's cloud and Google's cloud. We've run on bare virtual machines, we've run on Kubernetes. We've seen all the cloud has to offer, and tried…
I started working on this on June 20th mainly out of curiosity: I had heard that Firecracker had PVH boot support (which was in fact mistaken!) and I knew that FreeBSD could boot in PVH mode from Xen, so I wondered just how hard it would be to get FreeBSD up and running. Not impossible, as it turned out, but a bit…
A technical overview of Notado's migration to Fly.io
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…

I was pleasantly surprised by how easy it was to make it possible to push a PC’s power button remotely via MQTT by wiring up an ESP32 microcontroller, a MOSFET, a resistor, and a few jumper wires. While a commercial solution like IPMI offers many more features like remote serial, or remote image mounting, this DIY…
In 2022, it actually makes sense to build your own infrastructure for scientific computing if you're a university, NASA, or a growing bio company.
On my recent review of the Blitzwolf BW-P12 10000mAh Power Bank, a reader commented asking whether that particular power bank could be used as a makeshift uninterruptible power supply (UPS) for USB…
I got curious about an ExpressCard to NVMe M.2 NGFF adapter I saw on Reddit, so I got one to try out myself, ending up with a total of 4 SSD-s on my ThinkPad T430. Yes, four.
This week we conclude our look at nuclear power construction costs. So far we’ve looked solely at conventional nuclear power stations that supply electricity to the grid for residential and commercial use. But civilian power stations aren’t the only sort of nuclear reactor that the US builds. The US Navy has been…
An Upside-Down Backup Strategy I have a strange way of doing backups these days. When I save something, the master copy is in the cloud. If a file exists only on my local drive, it's not safe....
How I deploy my webapp using blue-green deployment and zero rocket-science
During one of my assignments, I worked with GitHub Actions pretty much every day. I implemented workflows, created new actions, and helped people migrate their projects from jenkins to actions. As much as I like actions – and I like them a lot – there are some things that caught me off guard. I have collected some of…
In actual supply chains, money is changing hands. A server manufacturer is paying for PCB fabrication, who is paying their suppliers for raw materials and equipment, and so on until the whole thing eventually loops back on itself when a mining company needs to buy a server.
Have you ever wondered about the performance delta between Caddy and Nginx? Wonder no more.
