lol rip, I ran out of monthly credits for the Mastodon server I run, digipres.club. Got to start paying actual money I guess.

i know where you can get some on aldhani

Tomorrow (Saturday the 17th) at 2 PM EST / 11 AM PST I'm streaming "Tunic" on Twitch. This is the second session in a row JUST trying to find page 22 of the manual. But, last week we found a large number of places page 22 isn't! So that's progress.

Watch at: https://twitch.tv/mcc111

Like this second! Come watch me DEFINITELY find page 24 this time for certain: http://twitch.tv/mcc111

Don't think I posted about this here: on Saturday 12/17 (tomorrow!), I'm doing all-day streaming marathon to raise money for Trans Lifeline! For every $5 raised, I have to play one minute of Dizzy. We are already at over three hours of Dizzy. This is gonna be a mess. Please stop by and donate!

Starting now! It's DIZZY TIME twitch.tv/obscuritory

theres an option to extract the source maps that needs a certain npm package installed, and theres an option to list all the trpc api endpoints.

a helpful file to check out for anyone interested in the api is sitemap.ts because it contains all the /api/v1 endpoints and what data they take.

also heads up i am not a lawyer, i am not telling you to use this to do anything malicious or against TOS! the only cybercrimes i commit are css crimes

sorry that the code is a bit of a mess, it was made for just me to use at first but i figured sharing anything is better than sharing nothing
