I haven't had coffee in several months due to acidity issues.
Three separate people have told me that drinking cold brew could help with that.
I am experimenting with cold brew today, and I am not sure if the mild discomfort is due to coffee or stress about the experiment being successful.
😂
I miss coffee. ☕

<quote>The year was 1812, and mathematical tables were a thing.
What are mathematical tables, you ask? Imagine that you need to do some trigonometry. What's sin(79)?
</quote>
I grew up with such tables. sin(79) was simple, just look it up.
what is square root of 53? No such table, instead had to use the logarithmic tables and what used to be 6th (7th maybe) grade (12 years old) mathematics.

But what is the actual PROBLEM with Mastodon?? Said one hundred dozen people over several months of threads here. So I wrote it up.
It's too long, but we got bad doors, stilt-walking French shepherds, water bugs, a bunch of @shengokai quotations, What The Fuck Is Up With Bluesky, and more.
FACEMINER Game: "Detailed simulation of Data Centre operations; manage RAM, processing power, memory, cooling systems, software upgrades"
"Indonesian Tribe feels their tradition is under threat from Smartphones; requests internet signals be halted"
Messaging Layer Security: "Using MLS, you’ll always know which other members of your Chat Group will receive the Messages you send, and the legitimacy of New Members entering a group is checked by everyone"

"#Mastodon and the fediverse offer a big, motivated, often super-generous ecosystem of toolmakers, devs, and instance operators who really, really want to nail big-world + semi-sheltered networking that is inclusive and welcoming"
