My solar-powered blog is now on lithium iron phosphate
In my last blog post I discussed how a small solar project - to power this blog on a Raspberry Pi - escalated into a full-blown off-grid solar setup, large enough to power the computer I use at the moment to write this update 1 . In this update, I want to discuss my battery upgrade.

On the joy of podman and auto-updates (2022)
podman provides an integrated auto-update mechanism, which I recently applied to all of my containers running on feldspaten. The mechanism is nice, but at first appears a bit counter-intuitive. In this post ’m trying to explain how you can use the mechanism and what to watch out for. I’ll start with the trap I think…

Moving Marginalia to a new server
So the search engine is moving to a new server soon, thanks to the generous grant mentioned recently. If you visit search.marginalia.nu now, it may or may not use the old or new server. It’ll be like this for a while, since I need them both for testing and maintenance type work. I’ll also apologize if this post is a…

Clog: Making a homegrown ClickHouse log for $20 a month
There was recently a discussion on Hacker News around application logging on a budget. At work I've been trying to keep things lean, not to the point of absurdity, but also not using a $100 or $1000/month setup, when a $10 one will suffice for now . We settled on a homegrown Clickhouse + PHP solution that has…

Switching to Fedora Silverblue
For the last 10 years or so, Arch Linux has been my Linux distribution of choice. The early years were a bit rough, and the process of moving to systemd wasn't without its challenges either, though the experience has improved dramatically since then. In spite of these improvements, certain issues persisted, such as…

root with a single command: sudo logrotate
Starting from the constraint that only sudo logrotate * may be run, and ending at root: abusing the log file flag to overwrite root owned scripts and ride cron to privilege escalation.

VyOS From Scratch – Edition 1 (set up your own router)
As a VyOS evangelist, maintainer, and more, I’ve been meaning to write a simple series of “how-to” guides for VyOS for a while. Sure, there are plenty of guides out there, but I think a lot of them fall short in demonstrating WHY you are entering specific commands.

We used to build steel mills near cheap power. Now we build datacenters
Why are people so concerned with hardware power consumption nowadays? Some common answers to this question are that power is critically important for phones, tablets, and laptops and that we can put more silicon on a modern chip than we can effectively use . In 2001 Patrick Gelsinger observed that if scaling continued…

Usenet over NNCP
Usenet, of course, originally ran over UUCP in quite a few cases. Since NNCP is quite similar to UUCP – in fact, you can map UUCP commands to NNCP ones – it is quite possible, and not all that hard, to run Usenet over NNCP. In fact, in a number of ways, it works better than Usenet over UUCP! Introduction to NNCP…

How to create portable Linux binaries
Creating application binaries for Linux that run on a wide range of distributions is a bit tricky, as different distributions ship different versions of various system libraries. These are usually backwards compatible, but not forwards compatible, so programs linked against older versions of the libraries also work…

We stand to save $7M over five years from our cloud exit
Since declaring our intention to leave the cloud in October, we've been busy at work making it so. After a brief detour down a blind alley with an enterprise Kubernetes provider, we found our stride building our own tools, and successfully moved the first small application out of the cloud a few weeks ago. Now our…
