They won't open source it because the rust code is very likely a joke. They are proud of just using two dependencies, don't know that their "statically generated" stuff is actually called server side rendering and are hosting this stuff on a fuckin laptop.
It's probably a project that will teach them a lot. But in practice their implementation is worthless to everybody else because they are obviously completely inexperienced.
That said, that project is likely not worthless to them because they will probably learn a ton of stuff why it's hard to build a search engine.
"Only two crates used". What's great about reinventing the wheel? A closed source project with big claims trying to reinvent everything from scratch. Nice project 🤣
That's exactly what I did and never looked back. Just installed code-server + a few vs code plugins. Automatically synced via some some scripts that push and pull+merge git commits, done. No need for one of those million note taking apps. I also installed polyglot notebooks for vs code to embed code into notes.
I don't think it was designed but that's nothing evolution is concerned about. Evolution is (as the name implies) about evolving systems and doesn't really say anything about how the first replicating "system" came to be because that's abiogenesis and not evolution.
The amount of data is a joke for location "streaming". There is no need to update the location every second, most people on earth don't travel with rockets. Updating the location at most every 30 seconds is probably more than enough for most usecases. Let's make it 15s. Let's be generous and just use two 32bit floats (could probably get away with 16bit half precision or fixed point). The size of the entire message (without meta data and encryption) is just 8 bytes. There are emojis that need more than that. And in practice people that can't share their location often just end up sending images, so the amount of data is definitely not the issue with location sharing. A single image you send on Signal uses more data than streaming the location ever 15s for a few days.
How is location expensive to encrypt? I share my location all the time but to do that I have to write an entire sentence to other people where I am. Just introduce a new message type (like with edits) frontend to enable location sharing. Location is sent every 5min or if the other person requests an update, than location is updated again (send location update request message to trigger response on the other side). Same encryption as everything else and easy to implement. Of course the devil is in the detail but the basis are trivial.
The "hardest" part would be to show the location on a map without leaking data but just add a warning dialog and open externally. Every link in Signal you press has the same privacy issues.
Mutations happen by chance but the result is not random, because natural selection is not random.
Update: Regarding your first part: A lot of people misunderstand the role randomness plays. Evolution is not random and not a coincidence but a consequence of any system that makes imperfect replicas in an environment that rewards (or punishes) certain traits.
And that's the issue I have with that. Imagine you are fabricio and you find this post. Next time you probably won't make it public even if there is a remote chance, that it might help someone else.
On busy parking lots I even open the windows to also hear what's happening outside.
