Jason Asenap (Comanche & Muscogee) reviews Netflix's 'Frybread Face and Me,' which he calls "a thoroughly original Indigenous coming-of-age film that speaks to queerness but is centered on the complexity of growing up ."

"How often does an Indigenous director get to use actors portraying characters from the tribes they actually belong to?," he writes. "The cast has a natural chemistry; their dialogue and reactions feel authentic."

TIL Thanks to Google search, that Ursula K LeGuin worked in the genre of "Dance/Electronic"

(this last sounds like a good band name)

I currently run upstream jitsi debian binary packages on a server used for various important (to me) things. This seems like a security nightmare, but I started during peak lockdown, and the tradeoff seemed worth it at the time. Now I'm trying to clean up some of these services, and I wonder about using some kind of VM or container. I don't have much experience with containers but I could spin up a KVM based Debian VM without too much effort. The target bare metal server has plenty of grunt. The only odd thing about my jitsi setup is that I currently piggy-back xmpp service off of the same prosody server. I imagine it isn't that much work to run a separate prosody server. So experience reports? Warnings? Alternatives to jitsi that are in Debian and work?

It shouldn't have to be said, but apparently it does. Queer and trans people have the right to exist.

I have a possibly tricky question for all of you people who are not my . I have collected a corpus of 1 to help tune

There are about 200k messages collected from two public mailing lists and the Enron corpus. In a fit of public spirit I thought I should upload it as a dataset to https://zenodo.org. But I have no idea what license, if any to put on the data set. Anyone with similar experience? Somehow the Enron corpus ended up CC licensed, but I don't know if any lawyers were harmed in the making of that decision.

I run a "minimal" system based on , but I'd like my laptop to suspend or shutdown when the battery power gets too low, to avoid running the battery right to zero. What is a reasonable to do this? seems like it might be part of the answer, but it seems like it is mainly glue to provide non-root users the ability to suspend etc...

Shout out to @dabeaz for making "Practical Python" 1 available under a creative commons license. It works well for the hands on survey of programming languages course I'm this term. We only have 12 classroom hours to devote to , but so far it's working better than my previous humble attempts based on "Dive into Python 3". No disrespect to the latter book, but somehow my translation into labs always seemed a bit disjointed. I don't yet know how the students are absorbing things, but to me the Practical Python based version seems to give a more coherent (and elegant) view of Python.

I am using the book/course unmodified, except that automagically adds backlinks to where given sections are referenced in my add-on materials [2]. That shows the benefit of CC I guess.

[2]: see the bottom of https://www.cs.unb.ca/~bremner/teaching/cs2613/books/practical-python/03_Program_organization/01_Script/ for an example.

For some reason [0], I never made the connection between "Redemption Song" and Marcus Garvey until I started listening to "The Monsters we Defy" based on a recommendation by @Annalee. According to Al Etmanski [1], the lines "Emancipate yourself from mental slavery, ... None but ourselves can free our mind" are based on a 1937 speech Garvey made in Sydney Nova Scotia. This is part of the same region where I now live, but I also did not know about Garvey's visits to Canada towards the end of his life.
Also wow, the politics of Garvey were a lot 😅.

[0]: OK, the reasons are not that hard to guess, if not exactly inspiring. My family listened to Bob Marley a great deal (one of 4 cassettes on repeat), but didn't mention Marcus Garvey that I can remember.
[1]: There are many sources that claim similar things, but here is one: https://aletmanski.com/impact/emancipate-mental-slavery/

Dear

I'm currently looking at annotations / decorations to a research programming language to estimate runtime non-asymptotically (i.e. gimme a number) in a simple execution model. I thought there might be (have been) some similar projects, but I'm not really sure where to look. I vaguely remember some work on proving loop bounds (e.g. polyhedrally). Any hints?

@christianp I had a similar experience in the Newark airport recently: it took me an hour, a train, and a shuttle van to reach a hotel 500m (and visible) my starting point. In this case the underlying issue is the many lanes of traffic to cross and lack of interest in pedestrians.

We've had a printer* for the last four years. No problems at all. Zero.

But now, the prints started coming out crumpled. Turns out there was a sheet of paper wrapped around a fuser roller, deep inside the printer.

Guided by the first 2 mins of this video, I took apart the printer, fixed and cleaned the roller, and put it back together. No tools needed, it's all just clicky plastic elements.

Works like new! 😊

This morning I'm looking at .
The first thing in the tutorial (https://typst.app/docs/tutorial/writing-in-typst/) is how to write a header, and it annoys me that it makes the same mistake HTML, and everything following HTML, made: you specify the level of the heading absolutely, and it's not scoped to a section of the document.

So when you want to have a heading one level lower, you have to know what level the previous heading was. And you can't tell how much of the document the heading applies to, only inferring it as going until the next header of the same or higher level.

I've always wondered why has
\section{name}
instead of
\begin{section}{name} ... \end{section}

Am I alone in wanting this?
