Serving a website from a Git repo without cloning it
It's fairly common to use git repositories as a vehicle for serving websites. The webdev pushes their changes to some branch of a publicly available git repository, and some web server somewhere serves the current tip of that branch as the website. Github Pages would be the most famous example of this.

Considerations for a long-running Raspberry Pi
Keeping a Raspberry Pi online and working with zero intervention for weeks, months, or years is somewhat of an art form. Several classes of things can go wrong, and you need to consider how your Pi will recover from each of them.

We might want to regularly keep track of how important each server is
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…

Why Certificate Lifecycle Automation Matters
If you’ve perused the ActivityPub feed of certificates whose keys are known to be compromised , and clicked on the “Show More” button to see the name of the certificate issuer, you may have noticed that some issuers seem to come up again and again. This might make sense – after all, if a CA is issuing a large volume…

I looked through attacks in my access logs
I've been self-hosting for over a decade. It's freeing because I own my data, and do not depend on any platform other than my cloud host, which I can easily switch off. Self-hosting gives much insight into what it takes to run a cloud service. Anyone

Ditching PaaS: Why I Went Back to Self-Hosting
I had never been a fan of devops/server-admin work. The sheer number of headaches involved in setting up the services, configuring them, automating them, and ensuring their reliability were just annoying and time-consuming. PaaS offerings like Heroku, AWS—and later—Railway, and Render, were appealing options out of…

Slashing data transfer costs in AWS
There are lots of ways to accidentally spend too much money on AWS, and one of the easiest ways is by carelessly transferring data. As of writing, AWS charges the following rates for data transfer:

Project Bluefin: an immutable, developer-focused, Cloud-native Linux
Today we "relaunched" ublue-os/bluefin as projectbluefin.io. This is a beta until Spring 2024. Bluefin is a custom image of Fedora Silverblue by a bunch of cloud-native nerds. We want a reliable desktop experience that runs everything but we're too lazy to maintain anything. So we

7 watts idle – building a low powered server/NAS on Intel 12th/13th gen
