Basically some way of encoding location so that, if two places are close to each other, you can immediately make out, but if they aren't you can't pinpoint where exactly the location is 📍
Don't know if that's mathematically possible, but if it were it'd be cool 📐
Reminder about Mastodon "private" messages. Aside from not being end-end-encrypted (and so visible to instance administrators), they CC anyone @-mentioned ANYWHERE in the body of the message (not just those listed at the start).
They are now called "private mentions" rather than "private messages", but if you don't fully understand the semantics, this behavior may be unexpected and/or cause unpleasant side effects.
Everything about this story is horrific. But the fact that #Facebook / #Meta turned over this family’s DMs to the cops showcases how evil these companies are and the vital need for #encryption.
