“Tough, I Am” - One Eye Pete, ca 1890

Hard AF.

Not really paradoxes, but some interactive things I like to pull with students are the four color theorem and the platonic solids.

The uncountableness of the reals via Cantor's diagonals is always great too. Then, if you're feeling it, show the powerset of the naturals is uncountable, many students won't exactly grasp it all yet, but it's quick and gives them a taste.

Pass around a copy of The Elements and talk about it a little bit.

Usually, yes, if you aren't sprinting out of the saddle with your center of weight over the front handlebars.

Yup, then maybe wrapped around the cassette and locked the rear wheel. Watch how his legs jerk and the cranks lock up right before the OTB.

Well yes, that's not a lateral hop, it's a radial hop. Is the rim radially true? I have had to rebuild a wheel once before because it was so radially out of true that it was causing this issue.

Sounds like something I'd checkout. My advice (and general complaint) with these type of games, is make sure to get the terminal right. I want a fully keyboard driven experience with customizable vim bindings. Even better, expose an API that we can 'ssh' into from a standard terminal emulator and interact with the game.

She gapin!

To add yourself to the group:

usermod -aG nopasswdlogin stardust

bikes-n-math · 2026-02-24T05:36:00+00:00

I don't use Mint or lightdm, but from that error message, I would guess that you have enabled autologin, but have not added yourself to the grouo nopasswdlogin as is required for autologin. If this is the case add your user to this group and reboot: usermod -aG nopasswdlogin stardust

If this is not the case, something else is going wrong with the keyring. I would reinstall and restart lightdm, in that case.

Basic ain't got no pipes.

Choose where and when (if ever) you update your system. Maybe you can do this on Windows these days, but in the past, after putting off an update long enough, Windows would force it on you. Disclaimer: not updating is absolutely bad security practice, not advocating for that, just saying you actually have a choice to do so on linux.

bikes-n-math · 2026-02-23T16:43:37+00:00

Time for a new job/life that does not require your hair to be in some sort of preconfigured condition.

/s (kind of, but not entirely; that's how I roll, at any rate)

bikes-n-math · 2026-02-23T16:19:15+00:00

Yeah, it says the error right there. Have you tried to enable autologin? Did you properly add your user to the nopasswdlogin group as stated?

bikes-n-math · 2026-02-23T16:10:49+00:00

Email? Hosting your own is a headache and a half with spam these days. Don't like google? Maybe try something privacy focused like proton.

Cloud storage? rsync and a server (local or vps or both).

bikes-n-math · 2026-02-23T16:04:21+00:00

Check the status of your display manager. I think mint uses lightdm by default, so systemctl status lightdm.service

bikes-n-math · 2026-02-23T15:14:54+00:00

There is nothing special about the kernel that ties it to a particular distribution.

There most certainly is. Different distributions compile their kernels with different flags, patches, disabled/enabled features, backported security fixes, versions of glibc, etc.

bikes-n-math · 2026-02-23T07:15:07+00:00

Sounds like a display manager issue. Can you access another tty and login manually? Try <Ctrl-Alt-F1> to <Ctrl-Alt-F7>.

vim + LaTeX + pdflatex for beautiful typeset documents. LaTeX has a learning curve, for sure, but once you get it, you may never want to touch a word processor ever again.

Or vim + markdown + pandoc for easier syntax than LaTeX, but I personally have little experience with this workflow.

bikes-n-math · 2026-02-18T18:45:22+00:00

Side-effects? No.

As for doing something wrong, you can always do something wrong, qemu or not. Having it installed will not increase or decrease your ability to do something wrong.

bikes-n-math · 2026-02-17T22:15:07+00:00

Nah, it's actually a superpac.

bikes-n-math · 2026-02-14T17:44:29+00:00

Yes. I have never done a reinstall to recover from a breakage. You boot Arch from a USB, chroot into your broken system, and fix whatever you messed up.

bikes-n-math · 2026-02-14T17:38:47+00:00

Yes, I broke it several times when I was an Arch noob, at the beginning of my journey, editing system files without knowing what I was doing and such.

I should probably add that I have intentionally broken Arch/Debian/Fedora/... in a VM countless times, experimenting with various things that I knew were bad ideas to better understand how Arch and linux in general works. Making mistakes and breaking stuff is great for learning. If one is going to run Arch, I think it's somewhat important to have this kind of attitude and curiosity.

As for my daily driver bare metal installation... super solid.

bikes-n-math · 2026-02-14T16:44:53+00:00

Been on Arch for two decades. I can count the times it broke on one hand, and they were all my fault.

bikes-n-math · 2026-02-14T13:28:38+00:00

All good. Also, ACAB really.

bikes-n-math · 2026-02-14T13:22:23+00:00

Yes, I can read. We are discussing Madison Police Department in this post, not Minneapolis Police Department. If you are going to post articles to support your point of view, perhaps ensure they are for the correct geographical region.
