• Alice blocks you
• Alice posts a chost
• Bob, who you follow, posts a reply to Alice's chost
• Bob's reply is not visible to you in the home feed, nor on Bob's profile
• If Bob links you his reply via third-party channels, you'll only see his reply; no indication that it's in reply to Alice, or even that it's a reply at all.

Mastodon does similar and maybe there's some safeguarding considerations I've missed but I'd really, really like it if we could instead adopt the twitter/bluesky model of at least telling you "hey there's supposed to be a post here but you're blocked from seeing it" as opposed to pretending it doesn't exist at all.

I took the HTTP Range header and wrapped an impl of Rust’s Read+Seek around it

which means I can “open” a URL as if it’s a file, and do random-access partial reads

so now I can do things like “hey open the zipfile at this URL and list the contents, don’t bother downloading the whole thing, just pull out the file tables” and it Just Works

I should split something into a bunch of 10MB .rar archives, rename them all to .jpg and post it on here, as a lark

alternatively, use .zip - and concat the .zip data onto the end of an actual .jpg

.jpg data is read from the start of the file, .zip data is read from the end of the file,¹ so you can concat them together and make a polyglot file that's valid as both

Note: it's been a while since i did this and my memory is probably not 100% accurate

1. for complicated reasons that boil down to "it's the easiest way for the format to support append-only edits"

edit: it has been brought to my attention that catgirls don't work for that, so,
