I been single for several years after my last relationship fell apart where I been trying to learn about how my communication patterns and behaviors contributed to that, and my neighbors have been fighting for weeks and it makes me so sad. Like they need help hearing each other and escaping their toxic dynamic but I cant just like shout out across the alley like "please listen to each other and try to express your needs and take accountability and cooperate!"

This speedrun of a game that was so viscerally frustrating to me I had to shut it off after 2m makes it look as satisfying as a Mario game. Can u imagine the frustration that went into this

anarchists are just people who want to unfuck the world while also having tactical and realistic beliefs about power

do servers in fancy restaurants really compliment people on how the food they want to eat is a "good choice" or is that just a thing in dystopian movies and accidentally dystopian movies for rich people

Archetypical LA "bike infrastructure" - if you paint a line next to the gutter, it is a bike lane.

here's a shell script that recursively removes metadata from pdfs in a provided (or current) directory as described above. For mac/*nix-like computers, and you need to have qpdf and exiftool installed:

Also present in the metadata are NISO tags for document status indicating the "final published version" (VoR), and limits on what domains it should be present on. Elsevier scans for PDFs with this metadata, so good idea to strip it any time you're sharing a copy.

You can see for yourself using exiftool.
To remove all of the top-level metadata, you can use exiftool and qpdf:
exiftool -all:all= <path.pdf> -o <output1.pdf>
qpdf --linearize <output1.pdf> <output2.pdf>
To remove *all* metadata, you can use dangerzone or mat2

More fun publisher surveillance:
Elsevier embeds a hash in the PDF metadata that is *unique for each time a PDF is downloaded*, this is a diff between metadata from two of the same paper. Combined with access timestamps, they can uniquely identify the source of any shared PDFs.
