please only vote if you are a BIPoC and have experienced persistent harassment on the fediverse

imagine your instance had a feature where your mods and mods from other instances could quickly and easily share block/bans across fedi, to more rapidly and thoroughly respond to toxic behavior, and to combat users who ban evade by switching instances

would you feel overall safer on the fediverse? would you want to use fedi more or more often?

everyone please boost :boost_ok: 🙏

Y’all: Rioting and looting doesn’t do anything.

Historians: The only thing in history that has worked for the general public inciting change has been a riot,a protest, or a looting- like the Civil Rights Movement, Suffragettes, and Stonewall.

Y’all: Well, violence isn’t the answer

Historians: MLK was peaceful and you still shot him dead, and America is one of the most historically violent countries in the world, how ironic.

JUST SAY YOU DON’T SUPPORT BLACK LIVES MATTER AND LEAVE instead of finding an excuse as to why you shouldn’t care that again and again and again Black people are completely brutalised by police and police are never criminalized for it.

Startling how many people are still using “but I learned this thing in biology lessons when I was 12” as an argument and believing it that to be sufficient. As if their school education taught them literally everything and nothing else is real.

A CRISPR baby but the only change is that there is an SQL injection attack coded in to the genome so that if it is ever sequenced, it drops all the tables in the company database

I think this is the first time I ever opened a book purely because of the font it was set in.

Request for help (librarians especially!!); Boosts++ 

I've got a request from a friend on another instance for help looking for scholarly resources about audience engagement with the performing arts, specifically marching bands, if possible

Would there be a librarian available to point us in the right direction?

I tried the Google maps AR walking navigation thing today. It is oddly futuristic, yet also somehow "why hasn't it always been like this this is so neat"

You ever need to do regression through the origin and really, like, _really_ want to cancel out parts of sums? Also, my google foo yields depressingly little info on the whole thing, at least on a level I can grasp (not familiar with regression in matrix notation yet, and multiple regression is also a topic for the coming weeks).

Sigh. Math is just too math for me.

Oh look it's exported/uploaded with background transparency. That doesn't help.

I need to derive the variance for the beta estimator for simple lineare regression through the origin (RTO), and let's say my math foo is insufficient.

I've been spending more time than I'm prepared to admit on the question of which fonts to use for the .tex template for… weekly assignments that nobody really cares about with regards to typographic sophistication and aren't even required to be TeX'd at all.

I switched my .tex template to scrartcl and now \emph doesn't do anything anymore and I'm not even sure where to start trying to fix it (╯°□°)╯︵ ┻━┻

If you're into self-inflicted pain like me (or just want to try to undertand how to kind of manage a TeX-distribution and use TinyTeX instead of TeXLive et al) … uh, long story short: This tool: ctan.org/pkg/texliveonfly can parse your .tex file and auto-install all the packages you'll need. It's magic. I love it.

Turns out my :rstats: package build on travis is failing because apparently the check process uses worldclockapi.com/api/json/utc to check for the local time. Which is currently 403. Which is… a bummer? One might assume that "figuring out what time it is" would be a solved problem, but alas, 'twas naive.

Ha! Finally found the issue. My best guess is that the cached data at cloudflare differs between my location and the location of the travis servers, otherwise I can't explay slightly different API response content for the same query at the same time that triggered the bug.

MFW a test repeatedly fails on travis but I can't reproduce it locally or on a different machine

So plants use photosynthesis to take in carbon dioxide and give out oxygen, but it doesn't directly convert the two.

That oxygen actually comes from water, and because Earth is a closed system, a lot of water molecules have been water molecules for a long, long time until a plant picks them up. A lot of them are drunk by animals in the meantime.

Dinosaurs were on Earth for 179 million years. So it's very likely that some of the oxygen atoms you're breathing right now were once dinosaur pee.
