<img class=" title=":fediverse:"/> Tiny Fediverse Family Sketches

I'm still penciling on the next episode of Pepper&Carrot, and this week, I did my daily warm-up before working on the pages with these sketches. Here is a cleaned compilation of them (credits in alt).

Fred, a firefox panda mascot I found for Pixelfed (pixelfed.org, inspired by artist Andy Cuccaro) panic on the back of a large whale smiling with headphones (https://funkwhale.audio/). These two are not official mascot, just approximation with random quick search. License: ??? (for Fred), my whale with headphones is an invention.

Misskey by Syuilo ( https://github.com/syuilo/ai/commit/15406d0f30c134e641267795e6eb6cc46a66888a ) under a MIT license as far as I can tell... ((It's really hard to find license info for Ai on Misskey... Not cool -_-)) The Mastodon is not looking like the official mascot, just a cartoony Mastodon.

I'm continuing to put my favorite comics up on Mastodon. Enjoy this helpful guide to bird photography.
A four panel comic titled "Bird Photography Tips". In panel 1, labeled Good Bird Photo, a Cape May Warbler stands on a branch. The caption says "excellent lighting, subject in focus, field marks clearly visible". In panel 2, labeled "Great Bird Photo," the warbler is caught mid-leap, and the caption says "peerless athleticism, levitation?, powerful". In panel 3, labeled Excellent Bird Photo, the warbler is facing the camera and is very round, and the caption says "borb, round, a good bird". In panel 3, labeled Exceptional Bird Photo, the warbler is frozen in mid-flight, its wings tight against its body so it looks like a torpedo, and the caption says "nyoooooom".

Journalists rarely read academic research. I say that as confession as both a journalist and journalism teacher. Having access to journals in a university library opened up a wider world for me. I tell students to take advantage of it while they can. I fear journalists won't.

#ResearchGate is getting rid of "Projects". A convenient feature, especially for #EarlyCareer researchers. It's time to build a federated social app for researchers. At @niboe, we are planning to design such an app on top of @bonfire. Are you interested to join such initiative?
We're retiring Projects on March 31,2023 After much consideration, we've decided to discontinue Projects. You can no longer create new projects, and we'll remove all current projects at the end of March. All of your research which was added to projects — such as preprints, experimental findings, and final papers — will stay on your profile and won't be removed from ResearchGate. Read our blog to find out what this means for you and what we're working on next.
