Basically this makes an X or Wayland system into a multi-seat terminal server surprisingly easily. After having done this once, I think I could scale it out to a ton of seats really quickly.

Why anyone felt the need to *build* this after, say, 1985 or so is beyond me. But it is cool regardless!

Today I learned about `loginctl` which, as expected, controls Linux logins. It's not quite as well documented as I'd like, but after tinkering with it for a while I've done some very cool stuff.

I put two NVidia cards into a 2U server and used `loginctl` to associate each one with an automatic login session in lightdm (plus one non-autologin session with the built-in VGA hardware). So without creating an xorg.conf at all, this system runs an X session for each card plus Steam to stream games!

@fribbledom very cool!

(Though there is also a GitHub data source plugin to directly grab the data without need for Influx: github.com/grafana/github-data)

Early voting in the past: show up, walk right in, vote, leave.

Early voting today: line out the door of city hall, down the street, and around the block.

And early voting has been running for a week already.

@fribbledom I'mma need to fork Mastodon so that I can have a server that lets me favorite this more than once

It took me way longer to get this working than expected but it's alive! 2.11BSD on a PDP/11-70 (emulated) logged in via a TeleVideo serial terminal.

Ready to go conquer the Great Underground Empire!

@fribbledom Part of the point of a settlement on Mars is that it can force us to learn more about technologies that can help us preserve Earth. The two goals are not mutually exclusive; they in fact reinforce each other.

@fribbledom Nice! Been there, done that, got the t-shirt :D

I have a bit of a crush on Grafana.

@peregrine can you expand on this a bit? It's a project I've been vaguely following (and have been wanting to try out but being blocked by the pain of dealing with ethereum) so I'd love to hear more about it!

@fribbledom I work at Grafana Labs and posted a link to duf to our internal Slack when you first announced it. Everyone *loved* it! So the crush you have is mutual :)

@fribbledom this is super cool! Thanks for creating this!

@gidi I think *they* would say that but I am not sure that *I would :D

The Golang tutorial never ceases to make me feel stupid. The difficulty curve just feels way off for me, like

• Lesson 1 - What is a keyboard
• Lesson 2 - Saving a file in your editor
• Lesson 3 - Running "hello, world"
• Lesson 4 - Massively parallelized asymmetrical quantum computing across 17 star systems

@fribbledom You can always put some tape on the stand to fix it!
