It's going on summer in the Bay Area, which means that it's warming up a bit both outside and inside (because air conditioning is Not A Thing out here). That, coupled with the not inconsiderable research infrastructure I have at home has left me wondering and worrying about just how hot my office gets during the day while I'm working. Now, I could just put a simple little thermometer on my shelf (and I did) but my concerns are a bit bigger than that. What happens if my office temperature reaches a critical point and servers start melting down on …

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 seems as if another summer is rapidly coming to an end. The neighbors' kids are now back in school, school buses are now picking their way down the streets, and due to Burning Man coming up it's now possible to eat in a real restaurant in the Bay Area for the next couple of days. I've been pretty quiet lately, not because I've been spending any amount of time offline but because I've been spending more time doing stuff and just not writing it up. I've been tinkering with Systembot lately, adding functionality that I really have a need …

I spend a lot of time digging around in other people's data. If I'm not hunting for anything in particular then it's a bit of a crapshoot, to be honest, if only because you never know what you're in for. You can pretty much take it to the bank that if you didn't assemble it yourself, you can't count on it being complete, well formed, or anything approximating the output of a human being (it usually came out of a database, but I think you see what I'm getting at). Sometimes, if I'm really lucky I'll just get hold of …

Longtime readers are aware that I've been a customer of Dreamhost for quite a few years now, and by and large they've done all right by me. They haven't complained (much) about all the stuff I have running there, and I try to keep my hosted databases in good condition. However, the server they have my stuff on is starting to act wonky. Periodic outages mostly, but when my Wallabag installation started throwing all sorts of errors and generally not working right, that got under my skin in a fairly big hurry. I reinstalled. I upgraded to the latest stable …

If you've been following the development activity of Systembot, the bot I wrote to monitor my machines (physical as well as virtual) you've probably noticed that I changed a number of things around pretty suddenly. This is because the version of Systembot in question had some pretty incorrect assumptions about how things should work. For starters, I thought I was being clever when I wrote the temperature monitoring code when I decided to use what the drivers thought were high or critical values for sending "something is wrong" alerts. No math (aside from a Centigrade-to-Fahrenheit conversion), just a couple of …

As the title of this post implies, I've been working on some stuff lately that's been taking up enough compute cycles that I haven't been around to post much. Some of this is due to work, because we're getting into the really busy time of year and when I haven't been at work I've been relaxing. Some of this is due to yet another run of dental work that, while it hasn't really been worth writing about has resulted in my going to bed and sleeping straight through until the next day. And some of it's due to my hacking …

A couple of weeks ago I ran into some of the functional limits of my web search bot, a bot that I wrote for my exocortex which accepts English-like commands ("Send me top 15 hits for HAL 9000 quotes.") and runs web searches in response using the Searx meta-search engine on the back end. This is to say that I gave my bot a broken command ("Send hits for HAL 9000 quotes.") and the parser got into a state where it couldn't cope, threw an exception, and crashed. To be fair, my command parser was very brittle and it was …

A couple of days ago I got it into my head to upgrade one of my Exocortex servers from Ubuntu Server 14.04 LTS to 16.04 LTS, the latest stable release. While Ubuntu long-term support releases are good for a couple of years (14.04 LTS would be supported until at least 2020) I had some concerns about the packages themselves being too stale to run the later releases of much of my software. To be more specific, I could continue to hope that the Ruby and Python interpreters I have installed could be upgraded as necessary but at …
