To answer that and above comments - it is a combination of form-factor and software limitations. Lack of adjustable hinge/base part and excessive OS sandboxing.

I think industry is moving to CMC materials for first stage blades, because nickel superalloys hit the limit of performance. Not sure if those can be 3D printed reliably.

To further explain my point but also support the root comment. Aluminium/steel/titanium airframe parts are usualy machined or forged. It is not possible to replace them with 3D printed parts just yet. But! All of jet engine turbin

Also, to elaborate on which parts can be 3D-printed. The latest and greatest breakthrough is using EBM (electron beam melting) for 3D printing second stage turbine blades from titanium aluminide in GE9X engine. Those parts are continuously

I know a bit about turbofan engines in aircraft. 3D-printed parts are already going into them right now , as we speak: https://www.ge.com/news/reports/airbus-gets-1st-production-j...

My hypothesis is that ethics has to evolve to match technology development for any advanced civilization, to avoid self-destruction.

by d_silin 6y ago
Considering the amount of pointless suffering in human life, I've inclined to believe that no super-intelligent mind will simulate reality like ours, on ethical grounds alone.

My impression was that Starlink relies on inter-satellite links to route traffic. We can use the same links for our own extended network.

In theory, yes. In practice, this will depend more on my negotiation skills when talking to Elon Musk and less on any technical challenge :)

Thanks, I’ll have a look. Didn’t realize ML models that small can work.

There is no competition at this price point. Our vision is exactly like you described, giving millions of people first-class level of access to software development platform in space.

Hey, do you have any sources for that to read?

More ground stations will definitely make things better, but 24/7 connectivity to assets in LEO will take monumental, Starlink-scale level of effort.

Well, that deserves a reply beyond the HN comment format. ESA hosted an event, called Phi Week, presenting many possible application cases in Earth Observation domain: https://livestream.com/esa/phiweek2020 If you don’

The bandwidth is not expensive. There is simply a lack of it. Most LEO satellites have 10-20 minutes a day communications window assuming single ground station. Amount of data you can download from a single pass is a tens or hundreds megaby

by d_silin 6y ago
Downlink is the biggest bottleneck at the moment. Your satellite camera or SDR can produce thousand times more data than the amount you can download. You'd definitely benefit from in-space processing.

There is a number of applications in development that will rely on in-space processing. Such as forest fire prediction, business intelligence from space (estimate the crop yields, oil reservoir levels, city planning and so on). Most of them

A better solution is to have an even number of people, but have a tie-breaker vote token that is passed around between everyone in round-robin fashion. In the event of the tie, the tie-breaker vote owner resolves it and passes the to toke

Semantics. I want some numbers out of the equations that will match the real-life engineering problem. Approximations/estimates are fine as long as I know the limits of their applicability.

Thanks for your reply! I definitely can see the gaps in my understanding of the subject now.

In UK. We definitely spent a lot of time solving DEs of various classes, and very little on "modelling" part. But I remember that numerical methods were covered pretty well too.

After studying both ODEs and PDEs, it did strike me that teaching this subject is incredibly counter-productive and outdated. The most important skill in this area is ability to compose differential equation from the description of the pr
