UI concept of BlueSky running on Opera 12 on Windows XP. The page has a blue sky background with clouds, a navigation bar on top with the BlueSky logo, a search bar, various links (home, lists, feeds, settings), and the current user on it. Below it, on the left side are tabs for different feeds, with the current feed's posts underneath, and the right side features a textbox for creating new posts and a list of recent messages & notifications, displaying no new messages and no new notifications.

Google-Skywater MPW1 and the FOSS ecosystem it spawned will be in our hearts forever. Sad news about Efabless. But hopefully a new champion will arise and the community will rebuild the ecosystem stronger than ever

very large chip layout. there are 26 columns of countless transistors in the middle. on the outside of the chip are power and ground rings, and a bunch of pads.

hit the halfway mark reverse engineering this crazy gate array chip (it's 1 of 2 chips used in the IBM MCGA graphics standard)

okay i didn't realise it had already been a week since installing it....

it seems good so far, aside from some minor annoyances with weird window features (like edge snapping, who uses that???) it's been stable, functional and so far does everything i need it to.

A photo of the Tangara, a small music player that is reminiscent of the classic iPod. It's shown sitting on a desk next to the box it comes in and a keyboard. It's playing "No Problems" by Ginger Root.

My Tangara arrived! Look at that cute little thing! And it's @oshwassociation.bsky.social certified open source hardware!

Fantastic work, @erinrose.bsky.social @buzzyrobin.bsky.social @jacqueline.id.au @ailurux.bsky.social!
