If you haven't heard of it, Sean Carroll's Mindscape podcast is worth a listen: engaging discussions about wide-ranging topics, but typically focusing on science and/or in conversation with scientists.
Understanding GNSS Orbits (GPS)
@lanodan Blender's open movie projects did a lot to both focus efforts and attract attention to the project from artists and developers. IDK what the equivalent would be for Inkscape: vector graphic design seems pretty niche and not very splashy @cwebber@octodon.social
Not really a "life pro tip", but I've found that not eating right when I get home does help me get things done after work. Something about sitting down and eating just feels like the day winding down, so it's harder for me to get up and take care of stuff.

I'm watching several episodes actually. "Hated in the Nation", the part where they make the fatal mistake of plugging in the abandoned drive and getting hacked. Just seems like an obviously bad idea for anyone technical.
@namark I was thinking there's a continuous stream. I get quickly out of my depth thinking about the physics of that, unfortunately
I just re-watched the "San Junipero" episode of #blackmirror. I still don't get why Kelly ultimately decided to join Yorkie. I figured that she was ultimately just like "screw this getting old and dying stuff", but Kelly was pretty angry before she left Yorkie that last time.
@namark IDK. I could imagine a shared-key scheme where all communications are encrypted with a stream cipher and your initialization vector is pulled off a well-known generator (maybe time-based). Not even saying it's not something you couldn't do some cryptanalysis on and figure out at least that there's a packet structure, but it doesn't seem hard to obfuscate enough so that you wouldn't see the signal unless you already knew there's a signal to see and what the scheme is. If the whole point was to make your comms look like noise to other potential intelligent life, it seems, at best, medium hard to achieve.
I think the question is really what ET's communication medium is. I'm not sure what our radio telescopes pick up now and whether we could distinguish a comms signal that looked random from random noise. Maybe they occlude stars to communicate over interplanetary distances but we don't see because we're not in the right orientation to see the occlusion?
is it possible there's a bunch of alien communication going on, but it's all encrypted so that it just looks like noise in our measurements?

free sewing machine, probably broken
So I've got a Singer 834 #sewing machine that I would gladly give away. It broke down yesterday again and I expect I could fix it again, but I am kind of tired of this happening so often, so I want to get a more reliable one.
The thing that is broken is the spinny thing that is supposed to tangle the lower thread with the upper (as you can see I'm clearly a professional who knows all the terms) -- it isn't properly synchronized with the needle. I suspect you want it only if you like tinkering with such devices or you want it for parts.
I can send it anywhere from Switzerland, but if the postal costs are too high I might ask you to chip in.
