Disclaimer: Times have changed since this article was written so seek legal and scientific advice from qualified personnel if you plan to try making your own superconducting materials. I am not qualified personnel or a lawyer. Do not try this at home. We live in a world in which possession of basic chemistry apparatus is illegal in some places, so do your homework.

Let's say that you need to be able to access a server somewhere on your network. This is a pretty common thing to do if you've got a fair amount of infrastructure at home. But let's say that your computer, for whatever reason, doesn't have the horsepower to run SSH because the crypto used requires math that older systems can't carry out in anything like reasonable time. This is a not uncommon situation for retrocomputing enthusiasts. In the days before SSH we used telnet for this, but pretty much the entire Net doesn't anymore because the traffic wasn't encrypted, so …

Longtime readers have no doubt observed that I plug a lot weird shit into my exocortex - from bookmark managers to card catalogues to just about anything that has an API. Sometimes this is fairly straightforward; if it's on the public Net I can get to it (processing that data is a separate issue, of course). But what about the stuff I have around the lab? I'm always messing with new toys that are network connected and occasionally useful. The question is, how do I get it out of the lab and out to my exocortex? Sometimes I write bots to …

Obligatory disclaimer: I AM NOT A MEDICAL DOCTOR. SEEK PROFESSIONAL ADVICE AND TRAINING.
There's really no good way to start an article about the epidemic of opiate overdoses and deaths in the United States. It's a terrible thing. Unlike a lot of articles out there and stereotyping that happens, a nontrivial number of opioid deaths are due to accidental overdoses of painkillers taken by folks who are trying to manage chronic pain. I say this as someone whose dental health history reads like Hellraiser fanfic. If you're in so much pain that you can't even think straight most of the …

EDIT: s/alice.bob.com/alice.example.com/ to fix part of the backstory.
Let's say that you have a server (like Prosody) that has one or more subsystems (like BOSH and Websockets). You want to stick them behind a web server like Nginx so that they can be accessed via HTTP - let's say that you want a browser to be able to communicate with those subsystems for some reason. Or more likely you have a web application that needs to communicate with them in the same way (because Javascript). Assuming that the above features are already enabled in Prosody …

In my last post about the Matrix network I covered how to set up a public Synapse server as well as a web-based client called Riot. In so doing I left out a part of the process for the sake of clarity (because it's a hefty procedure and there's no reason not to break it down into logical modules), which was using a database back-end that's designed for workloads above and beyond what SQLite was meant for. I'll be the first to tell you, I'm not a database professional, I don't know a whole lot about how to use or …

EDIT - 20200804 - Updated the Nginx stanzas because the newer versions of Certbot do all the work of setting up SSL/TLS support for you, including the most basic Nginx settings. If you have them there you'll run into trouble unless you delete them or comment them out. Also, Certbot centralizes all of the appropriate SSL configuration and hardening settings into a single includable file (/etc/letsencrypt/options-ssl-nginx.conf) for ease of maintenance.
A couple of years ago I spent some time trying to set up Matrix, a self-hosted instant messaging and chat system that works a little like Jabber, a …

It doesn't seem that long ago that I put together a Pi-Top and started tricking it out to use as a backup system. It was problematic in some important ways (the keyboard's a bit wonky), but most of all the supported respin of Raspbian for use with the Pi-Top was really, really slow and a bit fragile. While Windbringer was busy doing a full backup last week I took my Pi-Top for a spin while out and about, and to be blunt it was too bloody slow to use. At first I figured that the microSD card I was using …
