An entirely mechanical wireless keyboard for computers, which produces ultra-sonic tones that are picked up by a microphone connected to the host computer.

The keyboard has six metal bars, each of which are tuned to emit a distinct ultra-sonic frequency. Each button on the keyboard plays 2 of metal bars at once, which allows the keyboard to have up to 128 buttons.

To make eavesropping a little more difficult, every sold keyboard has a random pattern of button-tone combinations.

If you remember, the EHT also resolved the emission and shadow of M87 a couple years ago. Although M87 is much further away than Sgr A*, the two supermassive black holes look similar in size because M87 is about 1000 times larger than Sgr A*! (I did not make the graphic and will need to figure out who did)

Okay, I'm curious, when did you guys first hear about/join Linux? Please boost for a wider data pool. ​​

Ja oder nein? Letztendlich läuft doch alles auf diese Frage hinaus. Bitte ehrlich antworten und jeder nur ein Kreuz! (Gerne fleißig retröten, damit wir ein einigermaßen repräsentatives Bild bekommen!)

Time again to post the Hubble Extreme Deep Field. With the exception of about 3 objects, which are foreground stars in our own Galaxy, every object in this image is a galaxy.

Can you find the ~3 stars? There’s a trick to it!

The curb cut effect: for example, media descriptions right here on Mastodon help people who use screen readers, but they are also useful for explaining the joke for people who don’t get it, for translations of text, and for copy-pasting what would otherwise be just an image of text.

Did you know that the green lawn that is so common today was originally a way for the landed gentry to show off their wealth? It was meant to imply the owner could afford to have all this land being non productive, setting them apart from those whose livelihood depended on what they could cultivate.
From the beginning, it was an ostentatious display of obscene wealth.

Wer Journalisten zum Folgen auf Mastodon sucht - hier mal wieder die aktuelle Fassung der #JournaListe : https://gschichten.de/wp-content/uploads/journaliste.pdf

Should magazines ideally be saddle stitched (stapled) or perfect bound? RT for more votes

43 Jahre und zwei Tage lang ist die @tazgetroete immer erschienen (was anfangs niemand für möglich gehalten hätte). Am 20. April 2022 wird es zum ersten Mal keine taz geben. Der profane Grund: ein Stromausfall. Wir sind morgen wieder da! Gute Nacht!

Oh, also, no CDNs involved. This is self-hosted on a dedicated server of mine.

It's all just static stuff, so the likelihood the sudden traffic spike brings down that server is, I'd say, miniscule.

What an idea, eh? A rich, graphics-heavy "web app", implemented fully in HTML+CSS, no external imports, no thousands of dependencies, no CDNs, and no tracking.

I know, crazy!

I should probably blog about "making of"? 🤔
