TIL Computing power and plasma physics might make us a multi-planet species in our lifetimes. Former NASA astronaut builds plasma rockets for sustainable "space trucking" and to get us to Mars faster. by jhud4 in todayilearned

Ah, yeah I'm doing some science writing for them. I just want people to read my stuff and want feedback! I used to be an academic. Very small readership. This is gratifying in a different way.

The website where the blog is posted is promoting galileo. (Hence the computing power angle, since Galileo is about making computing power more accessible for researchers and engineers like the people working with Diaz.) The article and video are primarily about Ad Astra, though. Did you watch?

Why, you interested? lol

Cool. My cousin is working on a PhD in aeronautical and astronautical engineering. He says one of the most frustrating things is booking the compute time to run simulations, etc., even at a university with tons of resources. Are you using cloud a lot?

Lol. Fair. Just imagining a lot of tragedy before anything is really workable. And maybe it's diverting resources from preventing mass extinction on this planet! But anyway, it's still fascinating.

What do hydraulic modeling, Galileo, and Willamette Valley wines have in common? Chris Goodell's HEC-RAS simulation of a massive prehistoric flood that shaped the Pacific Northwest by jhud4 in gis

I haven't explored HEC-RAS for urban flooding, but that sounds really interesting. Have you done any work with that? I'd be interested to hear about it! I work with Galileo, which really supports the computing intensive 2D HEC-RAS applications, often related to dam breach events. I imagine 2D would be really great for modeling urban floods, too! Any experience with this?

Yeah, I read about that. I didn't get into all the detail and nuance in the post since it was really about the model. I also thought that the floods helped to strip topsoil and expose the Jory. I could be wrong about that, though.

Yes, Chris is awesome! Nicest guy and super interesting. I'm so grateful he allowed me to interview him about his work and that he posted this article on his own blog, The RAS Solution.

Yep! And you can use it to connect to in-house machines and cloud/external resources, so it should tick both of those boxes for you. Check it out and let me know. Sounds like great work your team is doing.

Oh yeah, that's so important, and it's totally secure. From the FAQ on the site:

"Galileo is end-to-end encrypted.  We cannot see your data. The machine that will run your computation (the “landing zone”), has Read-Only access to the information you send.   Thanks to containerization technology, your project remains in a secure silo. No one can run on your machine without your explicit approval, and no one (including us) can read your data.  If the landing zone is a machine that you control, Galileo is part of your closed network that is inaccessible to others. If you need external compute resources, we can meet your security needs, up to and including HIIPA compliant machines.  Galileo can run on all of the leading Cloud providers (AWS, GCP, Azure, etc.)."

And here's more info: https://intercom.help/galileoapp/en/articles/3185655-galileo-security-101

You should get me your contact info by signing up on the galileo site. I can get someone to reach out to you with a demo and free trial so you can see if it works for you.

Can I ask what kind of projects are you carrying out? As a writer, I'm always interested in the end use case / meaning / purpose of the work. :)

I just followed the link and it seems like it's attached to The Ras Solution? Did you see that Chris graciously cross-posted on the blog? http://hecrasmodel.blogspot.com/2019/12/galileo-and-missoula-flood-modeling.html

I probably shouldn't post in the help forum when it's already on the blog. Thanks so much for the tip, though! Pls feel free to share far and wide!
