#2Puff piece. Starlink is fundamentally not about providing broadband to anyone. It’s landgrabbing a finite resource - low-earth orbit space - before it’s worth is recognised by those who should be regulating it.
The broadband itself might be nice or it might be awful. It doesn’t actually matter because that was never the point.

#3Starlink is super exciting from an emerging technologies perspective —— (relatively) cheap satellite production, commercialized laser links, commercialized phased-array tx/rs, among others. These open up very interesting possibilities down the road.
These posts always have a thread about people wanting to work for spacex, but because of my pseudo-anonymity, I don’t feel bad about starting it: Does anyone know if spacex does fall or spring embedded software internships?

#4The article ends with this nugget about C++ shared memory state management, but I don't have the background to know exactly what they're referring to. Does anyone recognize this pattern and feel able to explain it to mere mortals?
> “We also have different tools so that any state that is persisted through the application is managed in a very particular place in memory. This lets us know it is being properly shared between the computers. What you don’t want is a situation where one of the computers takes a radiation hit, a bit flips, and it’s not in a shared memory with the other computers, and it can kind of run off on its own.”

This reply brought to you over a robust, fast, low latency and reliable Starlink connection.

It's a cynical perspective, but the downvotes are unwarranted. It's worth comparing to McDonalds, where a large proportion of the corporation's worth is in the real estate they hold.

#7"Starlink is currently in orbit at 340 miles"
Can we please stop using miles etc :( I am tired when people makes mistake like this.

It is about making money. Starlink is a money generating system that makes use of low cost launch made possible by SpaceX.
If it does use up most of the low orbit space it is because SpaceX is the only company that is even capable of launching that many satellites and making money on it. Until there is another challenger there is zero point in complaining, because competition is not even an option.
Since it is low orbit it is self limiting problem. Any low orbit satellite has a limited lifetime of a few years without power.

I think the most exciting part is their use of electric ion propulsion to maintain low earth orbit. If SpaceX ever goes bankrupt or something, the satellites will passively deorbit within 5 years or so.
