I can’t with these essays on leaving Twitter—the digital paradise—that fully paper over *years of harassment* organized on the platform (gamergate, yourslip, countless other examples). the company finally addressed harassment several years back (because advertisers were complaining) and progressively tweaked measures but it was by no means flawless by 2022.
@_dm @raph @adamshostack @mattblaze There are a lot of things can do with NOMINATE-like statistics once you compute them; Adam's idea is one. Might prefer to count blocks or follows (or boosts, stars, etc.) by users who are similar to you, or to other users you trust (which could, sure, use some kind of flow computation or something)

#Markdown and #CommonMark are often used interchangeably. The latter refers to the formal specification published in 2014, resolving the syntax ambiguities of the original Markdown spec.
CommonMark and “#pandoc;s Markdown” differ in subtle ways, which is why pandoc has an extra CommonMark parser:
pandoc --from=commonmark

In 1978, Klaus Steffen found a flexible polyhedron that doesn't cross itself! With 9 vertices, 21 edges, and 14 triangular faces, it is known to be the simplest possible non-crossing flexible polyhedron.
It's hard to understand Steffen's polyhedron by looking at it! In the image here, I believe the top face has been cut open so we can see what's going on underneath. For more details go here:

plan9port (Plan9 from User Space) running on NetBSD/i386.
Pretty sleek and very lightweight!

So, the European Union has set up its own Mastodon instance, EU Voice, as an official channel/platform for all its many institutions - what a great initiative https://social.network.europa.eu/about

Perhaps at some point I'll write a thread on my deep concerns about our reliance on Google Scholar.
For now, though, why on earth does Google Scholar not let you sort your search results?
You have basically one choice: to see them in "relevance" order—and we're not even told the secret formula used to determine relevance.
You can also sort by date—for papers from the past year only.
It's really crazy that a mature tool supposedly designed to serve the community would be severely limited.
@cuchaz Compiler optimizations generally free to leak secrets. Only guarantee you get the right answer, not that nobody else gets it
@_dm @raph @adamshostack @mattblaze FWIW was wrong about DW-NOMINATE. Is a bit more complicated than that.
@raph @timbray The structure of Twitter pervasively encourages trolling: don't have enough space to write anything interesting, just to provoke a strong emotional reaction, and your metric of success is how many people you provoked a detectable reaction from. The UI is full of numbers measuring your trollishness. Maybe is unsurprising that discussions about Twitter have more heat than light.

"I wrote this to help us select timestamps for the start and end of Q&A session recordings for EmacsConf 2021. Finding the right time in MPV was hard because it didn’t have a waveform view. Audacity could show waveforms, but it didn’t have an easy way to copy the timestamp. So the obvious answer is, of course, to make the text editor do the job. Yay Emacs!"
@DenialShown @iridescentFluid in reality Matt Blaze is not an example of someone "unfamiliar with the intricacies of Free/Libre Open-source Software", is just making fun of you :)
@raph @adamshostack @mattblaze @iridescentFluid DW-NOMINATE is just the first couple of principal components of the voting matrix, right? Maybe you could take the first few principal components of the blocking or following matrix. Maybe you'd get a right-left component but also a "patronizing jerk" component, a "spammer" component, a
"celebrity" component, etc. I think that might operationalize Adam's idea usefully.
Magnesium Combustion System Design Log
@ACTupper In a sense, a magnesium-air cell is a magnesium combustion system. Is just more convenient for many purposes by not needing a heat engine to convert its output to work. Safer too of course.

Fun fact: sharing this link on Mastodon caused my server to serve 112,772,802 bytes of data, in 430 requests, over the 60 seconds after I posted it (>7 r/s). Not because humans wanted them, but because of the LinkFetchWorker, which kicks off 1-60 seconds after Mastodon indexes a post (and possibly before it's ever seen by a human).
Every Mastodon instance fetches and stores their own local copy of my 750kb preview image.
(I was inspired by to look by @jwz's post: https://mastodon.social/@jwz/109411593248255294.)

- hadn't been sentenced or even convicted
- hadn't shared his JSTOR articles
- openlibrary never had the goal of cataloguing all works, just all books

@mattblaze Jesus. Thanks for being you.

@ACTupper Unavoidable to have at least some of the magnesium molten when nearby magnesium is on fire ;)
Other end of the spectrum: there is maybe a magnesium version of aluminum-air battery?
