I am a big fan of imports_granularity = "Crate"
group_imports = "StdExternalCrate"; use it in all projects. It's a great feature!

I think this is why some of the best games are by smaller groups; less Corp pressure to confirm. Most of my favorites are by small or mid-sized, usually European companies. Blue Prince, Talos Principle, KCD, The Witness etc

We have to know the word so we can bring it back

I think I learned this trick from an earlier vid of yours. (And 50%) I wonder if the pure glycerol gets on the walls, if you can arm-centrifuge it. (Stand still and spin it around out) to get it to the bottom, or if it's too stubborn.

Addendum: Stay away from OpenSCAD and FreeCAD. Your time is valuable.

SolidWorks slaps. But probably too expensive unless you have student or veteran credentials. (Then it's $25/year).

Biggest tip: separate concerns. E.g. CAD, printer tuning/slicing, and design-for-manufacturing (tailoring your CAD to 3D printers) should be decoupled

This book slaps! (All/most Sagan books do. I think SoFA is especially relevant right now to help people understand each other)

I've never witnessed the take off. Once airborne, they seem to soar endlessly. I bet they put those wings into motion briefly! (Or not based on waiting for an updraft??)

I think dreaming and exploring possibilities is a nice thing to do. Critically, but it's so easy to point out how or why something couldn't/shouldn't work. Then find out there is one or more incorrect assumption. Maybe I'm too half-full. It's a bal between this and not wasting resources on dead ends

No, but Django slaps. The rust web ecosystem is mostly Flask-analogs; suited for microservices, but not websites. It's all Async as well. Web backend is one area I don't feel rust is ready for yet. (But would like it to be!)

Did you dump the MG due to maintenance problems? Or really wanted Bluetooth. Seems like a winning move other than that

Why do you think they sometimes spread their wings like that? Drying out?

Is there any way to buy these without making a Zazzle account? It is spinning indefinitely when I attempt

An optimistic assumption about the universality of empathy level!

As Emil said, prob within tolerance. Granted, I've measured much closer to spec for ICM42xx @ 8k. In some applications, you drive the whole system operation from IMU updates, so can be important. You can add a dedicated XTAL for some IMUs to get tighter timing.

A next step may be applying a digital filter; useful at that measure rate. Maybe an IIR lowpass depending on the application.

We can do better! Leave the hype and lies to Silicon-Valley companies and VCs.

This is fantastic! Is the intent to use this to tune and validate traditional MD models using data that better captures protein flexibility? Or new/augmented models?

I'm excited about it! Loved the Fagles Odyssey translation. Loved Nolan before I knew who he was - just knew my favorite movies were A, B, and C... Turned out they had the same director. Stoked for this!

I loved the science MOOCs from MitX that came out ~10 years ago. Then... nothing. They stopped producing ones, and the others I found weren't on the same level. Bummer. (But those originals are still available!)

I wonder how *heliotropism* as described in this video relates to the *heliotrope* plant

Another example how this post illustrates her point is the venom aimed at someone for not dismissing Weinstein.

I would describe something different as the takeaway of this video. This confident dismissal, replete with scare quotes, weasel words, and other cues of an exaggerated reaction is a good example of what Sabine is raising awareness of in this vid.
