I don't see mention of a license in the repo, but I wonder if informal permission was given to make the sources public?

A lot of smart amateurs discuss all things astro at the Cloudy Night forums; the subforum where topics such as radio astronomy are discussed is here: https://www.cloudynights.com/forum/88-scientific-amateur-ast... Could be worth a look if you're seeking ways to contribute to the area.
For a macroscale analogue, imagine a large 3D grid of microphones all recording sound. If you fired a cannon from inside this grid and looked at the waveforms from all the microphones, you could work out where the cannon was, and also form a pretty good guess of what direction it was pointed.
Which makes me wonder if Apple's been funding development, perhaps for some time.
The middle sized bits are occasionally useful to (carefully!) finger-drill a tiny hole through a plastic part. They're rigid, very sharp, but pretty breakable if you're not careful.
The 0.1mm bit is so small that it's upsetting even to look at. I've never taken it out of the case.
There is a small but active multiplayer community. (Find it on the community Discord server.)
I think universities will never be able to compete for engineering talent until they can create attractive career paths for people who aren't professors.
Your ship moves freely in all directions, and your speed is proportional to the square root of the number of independent directions you're moving in. Fly forward, speed is one unit; fly forward + sideways, speed is 1.41 units; fly forward + sideways + vertically, speed is 1.73 units.
There's a long, challenging learning curve to making best use of this mechanic.
I recommend committing this to muscle memory. It takes two fingers, but is more comfortable than reaching for escape on most keyboards.
I prefer mapping caps lock to control rather than to escape, but that's another good alternative. But in any case it's nice to have another option for quitting vim in case something terrible has happened to your escape key, as it sometimes can (sigh) on modern laptops.
If you have a pair of binoculars already, get some kind of tripod for them, or improvise something with a reclining lawn chair -- anything that can stabilize the binos and let you point them upwards comfortably. It's surprising how much you can see with medium-quality binocular if you can keep them rock-steady.
A six or eight inch Dobsonian telescope is a good next step. The entry-level models are cheaper than they look, and the optical reach greatly exceeds that of cheap department-store refractors. Last I checked, pandemic reality had made them hard to find new, but they occasionally go for a song on Craigslist.
Look up a forum called Cloudy Nights for much, much more info.
"Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children."
It is also spending the health of the world's fragile ecosystems.
So I looked it up on wikipedia. And learned about the mites.
When I looked closely at the rind of the the cheese I'd bought-- sure enough, it was busy with tiny, transparent crawlies.
I still like mimolette, but there's something in the back of my brain that cannot forget the mites. The innocent bliss of that first experience is impossible to recapture.
Here's a thread in the amateur telescope subforum about the instrument that discovered this comet. There's a photo of the telescope and of Borisov four posts in to the thread. https://www.cloudynights.com/topic/677286-homemade-065m-f-15...
That particular subforum is full of people who make their own telescopes in their home shops, and it's a fascinating place to visit. From what I can tell, this particular telescope is an extreme example, an instrument manufactured to professional standards by a well-resourced optics professional working in his spare time.
But even granting that both affected OS flavors have serious DoS issues, a service that used a mix of OS flavors in its servers would be more resistant (not impervious) to attacks based on these TCP problems than a service using only one flavor. So do you really count this as a failure of N-version programming? (Honest question! This is not my area of expertise.)
Do you feel any more or less optimistic about what's coming in privacy law, having done this?
Any part of the experience that was especially surprising?
Edit: wording.
