@trinsec We're not sure, but there's probably some Corgi in there. When we walk her, almost literally every day someone will stop and ask, "What kind of dog is that?"

Hmm, that's odd. If I click on the hashtag in the quoted toot, it doesn't find the quoted toot! Can anyone explain what's going on?

(This was true before I quoted the toot, so that's not the issue.)

1. Feeling much better physically.
2. Violet got to attend Zoom meetings with students (and, not being aware of this fact, was very relaxed).
3. A fire in the fireplace.

You know how most people just have one phone number?

That's possible because all phone providers in the world federate together. No matter which provider you use, you can call anyone anywhere.

Well, Mastodon (and the Fediverse it's a part of) is the same thing but for social media. The Fediverse address on your profile is enough for people on other servers to follow you and interact with you. It looks like this:

@ (username) @ (server)

There's a video about it here:

@derickflorian @vern Unfortunately, this feature doesn't work very well.

A sincere tip for longtime fediverse people who would like their friends to stick around here longer than a week:

If you're on Mastodon or Hometown, you can click the "bell" icon in the profile of someone you follow. This will make it so that every time they post, it will appear in your notifications like an "@". I am enabling this temporarily for friends so that I remember to interact with them. This is important for making this place feel more lively and helps people stick around!

If you're wanting a simple quick way to explain how Mastodon works, there's an official animation from a few years ago which goes over the general principles. Here's a copy of it someone uploaded to the Fediverse:

The original video is on YouTube if you prefer that:

The principles explained in the video also apply to the whole Fediverse that Mastodon is part of: many servers talking to each other to form a single network.

@trinsec It does seem like almost every computer problem comes down to some variation on that idea. It works because maintaining state is tricky -- perhaps an argument for functional programming.

A problem in teaching with interactive notebooks (e.g., ): students tell me, "I typed exactly what you did, and mine doesn't work." Now, sometimes it's not *exactly* the same (e.g., = vs == or the wrong kind of brackets).

Other times it *is* the same, but they had previously run some erroneous code that redefined some function or variable. Perhaps they redefined max to be a specific list rather than the built-in functions that returns the largest element in a list.

That code is no longer in the notebook since they edited it trying to fix their mistake. Restarting the runtime environment usually fixes this, but it's a nasty issue to track down.
