Thanks for the response! I was trying to allude to what you are describing with the bit (ha) I mentioned about higher order thinking but you obviously articulated it much more effectively. I guess I’m not sure it’s obvious where the right l

I think this idea is so common now that it is almost the standard for technical documentation at this point even if people don’t know it by that name.

To be fair, people will still be people… if the sludge/protein mash can be mildly upgraded to diversity/quality comparable to MREs (not that I’ve ever had one) sure, but for long term space flight it seems plausible that the psych

Take a look at the paper I linked, specifically section 4, which illustrates finding force laws to match the desired dynamics of a real physical material (in this case, Delrin, including elastic and plastic deformation. I guarantee you will

Okay, fair, I was using fluid loosely (and inaccurately) to mean both granular and fluid behavior. But there’s nothing inherently incompatible between fluid dynamics and the discrete element method as far as I am aware, just like there is n

Interesting. I wonder what parts of this approach could be adapted to DEM models of solids. For those unaware - even though DEM is naturally chosen for fluids, depending on how you configure the force laws between particles you can easily m

I agree with you that it is correct from a logical perspective; I’m talking more about a narrative perspective. Any paper benefits from having at least one or two non-toy/bon-benchmark problems IMO.

Very cool paper, code in the repo looks good and easy to use as well. After a quick skim of the paper, I feel like it suffers from a pretty common flaw (one which my PI often points out to me in my work, so I guess I’m just extra attuned to

There’s no better introduction to signals and systems than a modular synthesizer IMO - the combination of tactility and audibility for multi-sensory learning is so great at building intuition - and more importantly, excitement! - for signal

I would say that, at least for me, PyMC’s main advantage was in DX. I just found model construction much more straightforward and better aligned with how I wanted to assemble the model. This textbook/walkthrough is great: https:/

There are plenty of papers which look at precisely the economic and carbon tradeoffs of these sorts of processes. It all just depends on where you are. When you have a clean grid and a cheap grid, these methods become pretty feasible. Take

Another thing to keep in mind is that having AI/ML surrogates which can evaluate expensive functions faster can also be integrated as an information source in model predictive control algorithms.

Only mildly related, but has any one else been using Martin [0] for tile serving from Postgres/PostGis? It’s been a huge benefit to me and probably my favorite open source map tool right now. Martin + Deck.GL is such an awesome combo.

Obviously this is just a binomial distribution, but another thing to consider I suppose would be if all trials are performed sequentially or simultaneously. If performed sequentially, on the one hand, you have a non-zero chance of not needi

Haha, yes I know! You also have airspeed, perspiration, metabolic rate, clothing levels, and transients (eg moving from a hot space to a cold space) which all affect the phenomenological experience- but we do consider all of these effects t

Yeah the account is from like 2019 or so. But still, I’m spinning everything up with Terraform or AWS Copilot, so it is still an active choice on my end to put it in us-east-1.

Am I the only person who is shocked to realize that this is the same Perun who does strategy gaming YouTube tutorials on a related channel!? I had seen a bunch of his Terra Invicta content… had no idea he also did actual military analysis?

There are some great scenes in Rebels of the Neon God [1992] by Tsai Ming-Liang (Taiwanese filmmaker) where the main characters steal the main pcbs from some arcade machines and try to resell them to the arcade owner lol. Wonderful film, re

Thermal comfort is still the number one thing. Visual comfort (primarily glare, but also the frequency spectrum of the light/overall light levels matter too) and ventilation do matter too though. Everybody knows what it’s like to be in

Another major area for decarbonization is also just better design - just by making it easier to fabricate and deploy shaped beams/floor systems which allocate material in a way that mildly follows the moment diagram, you can knock out

The authors do mention approximately equivalent carbon footprints in their LCA, but they don’t really explain how they account for the energy involved in heating the corncrete. If they are assuming a clean grid or renewable source already,

Yep, the authors do a relatively straightforward LCA and estimate essentially equally carbon footprint between concrete and “corncrete.” Point still stands - it’s a major goal of building technology to mitigate the embodied carbon of buildi

Alternatively, some other researcher can say “cool, some problems I can try to address with future work!” Or it can go by the wayside. Both outcomes are fine. But no need to pre-emptively dismiss something that is obviously not being pitche

All concrete is more aggregate than binder… but it’s the binder that matters from an emissions perspective.

Interesting. The degradation in wet conditions seems like a major challenge to solve. I initially was skeptical of the utility when I saw the mention of heating requirements, but the temperatures aren’t that extreme, and seem very reasonabl
