Hello from !fluidmechanics@discuss.tchncs.de ! Thank you for starting this community.

Windows 11 is enshittfying a feature that let you skip making a Microsoft account

There, FTFY.

I agree. Also, if you gave tons of compute power and DNS using Navier Stokes, it may feel that with CFD provides an answer; although it is approximate, it is a decent one. To me, the issue is every single time we do practical CFD of a whole city or an automobile etc. , we need specialized models that fit the flow regime. Even with petascale compute power that most supercomputers in the world are equipped with, once we simulate Navier Stokes + a turbulence model + some custom boundary condition + other microscale model, the approach is not generalizable and needs deep knowledge.

This deep dive by Sreenivasan & Schumacher explores the math, physics, and engineering challenges of turbulence—from Navier-Stokes equations to intermittency and beyond. A must-read for anyone fascinated by chaos, complexity, and the unsolved mysteries of fluid dynamics! 🌪️🌀 #Turbulence

Rheology of rubbing mud reveals that it is "shear thinning". It rubs like lotion and fills in the holes.

Great if it is done right. This will put a stop all those screenshoted memes from Fediverse.

The witch trial which explains duck typing perfectly.

Yeah, deal with it, Copilot/LLM plugin!

FWIW, I agree with you, partly because the last panel is uncomfortable to look at the anxiety of getting ragged in the public and also because recirculates the stereotype that "X for Humanities" courses are somehow inferior.

Simple, replace sin with 1/cosec everywhere!

I don't get it. Why Batman?

IIUC, copying over RustPython parser is an interesting detail, but that change happened earlier (2023!) when they were building Ruff, so it is old news. This piece of code called red-knot seems to be mostly original work, as far as I can tell.

Actually, it was invented by Douglas Engelbart in Stanford in the 60s

Xerox (re)made it for the PC in the 80s.

Actually it started with spices, like black pepper.

Then they came with guns and did the "divide and rule" thing, by letting the kings fight each other.

 

I remember using Audiograbber at one point and was surprised to see it was still maintained.

Or in other words which forces keep electrons in orbitals and prevent it from flying away or crashing into the nucleus according to modern understanding?

TLDR: To remove by shaking one would need accelerations high as 24g, which can damage the ear. A couple drops of vinegar or alcohol in the ear will lower the surface tension and make the fluid easier to remove
