My layman guess would be that shortly after formation Earth was just a ball of lava that destroyed every organic component so when the surface solidified it was sterile.

Absolutely not. It's like opening a hood of your car, taking picture of what you see and then try to build replica of the engine based on that.

Add audio buffer on top of that when you don't hear changes instantly but with a delay...

European Amigas got Power LED dimmed instead of being completely off.

You can just use "branch always" but to the next instruction (:

One thing that I haven't seen mentioned here is that shorter line limits (80, 120) make my life easier for non-trivial merge conflicts and diffing changes.

That the cell phone networks went down is a criminal negligence and should be prosecuted.

Yeah, I can't reach out their website from Denmark for some unknown reasons. On top of that the most recent update of their RSS feed server fxxxd up my news reader so I'm even less inclined to see whatever they do because it looks like they're not very competent technology-wise.

I know all of that. I wanted to provoke parent commenter to let them see that the Bernoulli effect doesn't explain my two examples.

I think you wanted to respond to the parent comment. My questions have been a lead to debunk myth that the major contributor to the lift is the Bernoulli effect.

Explanation based on Bernoulli effect requires longer path of air taking on top than on the bottom of the airfoil to create speed/pressure difference. With symmetrical airfoil both paths are the same regardless of the angle of attack. So when you mention AoA you implicitly lead to the explanation that lift, in majority, is not based on the Bernoulli effect.

I've read excellent article debunking the Bernoulli effect and lift many years ago, I'm not sure I can find it again...

> No. What causes lift is the differential in pressure between the top and the bottom surface of the wing.

How do you explain airplanes that can fly with wing with symmetrical cross-section profile?

How do you explain airplanes flying upside-down?

"The main goal is to make everything as easy as possible, says Kristina Behr, Google’s VP of product management for the Workspace collaboration apps."

Looking up Kristina Behr on LI it looks like she jumped ships from MS to Google slightly over a year ago. At MS' last post she's been responsible for "Empowering frontline workers to achieve more with comms-first productivity and workflow solutions" listing following achievements:

* Introducing Microsoft Teams Premium, the better way to meet | Microsoft 365 Blog

* Microsoft Teams for frontline workers: What's Live and Coming Soon

and so on...

Yeah, I'll pass :)

Regular LEGO sets are not intended for small kids, Duplo sets are. Every LEGO set comes with suggested age range or suggested minimum age on the box.
