Plane Hunters: https://www.plane-hunters.com/ I've been running this for the past few months. It's a search engine / aggregator for used aircraft. It's really hard to search for us…

BETA Technologies | Full time | on-site or remote | South Burlington VT We build the world's highest performance electric aircraft. You can read more about our latest 6,000 lb airc…

NASA Helios was quite expensive and tricky to build, with not a lot of margin left for useful payload. There's a weight runaway that occurs with solar powered aircraft, look at Fig…

It's online now! Sorry it had the usual HN flop.

For sure, but they have a limited range of packages installed, and can be tricky to tune towards a specific need.

You can already do this exact thing with a Python library on the user machine, see here for install instructions: https://gpkit.readthedocs.io/en/latest/installation.html The inten…

Yes, there was an issue with someone nuking the compiler box, and we're working on fixing the demo up. This does more than LPs, it lets you formulate GPs, which are a way of doing …

Wow, that is really beautiful. Topology optimization is cool stuff. I think it's key for optimization to be fast so that the designer can get a feedback loop going between the comp…

For sure, there's a lot missing, title is probably misleading. Definitely nothing new in terms of the CAD, browser CAD has been well done, just look at professional products like O…

This is correct, much better than what I said.

Yes it's considering the weight of the battery, as well as the weight of the motors. It doesn't factor in the props, I didn't get around to that. The props have inaccurate geometry…

I think by react you meant react to, which was fair enough, it was dodgy as. Now running well. The property of getting a guaranteed optimum is something that arises from setting th…

Fixed it, didn't know about pythonpath with gunicorn.

Nope, I just have no idea what I'm doing.

Currently solved server side, though assembled on the client side (see console) with gpkitjs and then passed through to GPkit. Packages here: https://github.com/lochieferrier/gpkit…

The difference is that there is a simple physics model that's driving the dimensions. So the arms are getting resized according to beam bending, the battery is a certain size for t…

This is my first time putting something up, everything is breaking, fixing it now.

I wrote the article, what you and everyone else has said is super true. I liked the Apollo 11 missions as much as everyone else, and I think I am off base. It's not a sport.

Hey man, I think you're off base here. The problem is that the Moon does not have significant resources, so you can't really make anything on the Moon and then launch it from there…
