@christianp @RefurioAnachro And so far for all we know the email might say "please help, my computer is stuck in comic sans and it is driving me crazy" in which case they can't really be blamed.

I have received a tech support email written entirely in Comic Sans.

What is a REALLY BOG SIMPLE way (and a link to a clear and concise guide) for a Twitter user to set up a Mastodon relay bot?

I think this might be a good gateway drug.

Band name of the day: deeper dimensions of the profane

runit (the supervisor and related tools) and runit-init (the package that replaces /sbin/init) should absolutely be separate packages. Do you mean originally you couldn't install runit without replacing /sbin/init?
I was disappointed when runit-init, the package for turnkey switchover, disappeared in Debian 7/Wheezy. But it looks like it will be back in Debian 10/Buster!

It worked without a hitch for me on Debian 6/Squeeze.

@RefurioAnachro well I'm going to keep running systemd in production for some time, until I test out removal for as long as necessary for me to feel comfortable.

Rules for production machines are different than rules for my personal server, for obvious reasons. ;)

Time may be represented differently:

- discretely or continuously (Z vs R)
- with a finite period or not (Z/kZ, R/Z = S¹ = T¹)
- invertible or not (Z vs N, R vs R₊)

And in all of these cases the intuition is more or less clear. But what about multi-dimensional time, with multiple generators, not linearly ordered, e.g. complex? What may be the intuition for that? Some kind of multiverse?

@RefurioAnachro I'm wondering about this part of the blog it linked to -- a sly joke or?

This is neither hairsplitting nor special pleading but a need we feel as computer theorists who have used strongly-typed programming languages. rjlipton.wordpress.com/2018/09

Four days after Atiyah's presentation it's clear that his proof is wrong and can't be fixed. The purported proprties of his Todd function are contradicting, so it cannot exist.

The Aperiodical's closing piece by @christianp and Katie Steckles puts it all in perspective. Which is something the media didn't manage to do properly:


“Being wrong isn’t a bad thing like they teach you in school. It is an opportunity to learn something.” – Richard Feynman

Repost, forgot the image, sorry.

> In fact, Gaudi designed a church in Barcelona using a web of strings and weights to find correct shapes for the arches -- of course, the actual building would have a shape like the reflection in a horizontal mirror above the strings

Also from ch1 of that mechanics textbook:

Woot Gaudi!


> Let's define an ideal arch as one that doesn't have a tendency to fall apart sideways, outward or inward. This means no shear (sideways) stress between blocks, and that means the pressure force between blocks in contact is a normal force -- it acts along the line of the arch. That should sound familiar! For a hanging string, obviously the tension acts along the line of the string.

> […] the ideal arch shape is a catenary.
