Yes. It's the classic ice skater effect. Climate gets warmer => Ice (on mountains) melts. Molten ice = water flows down into the ocean, moment of inertia of the Earth is reduced => Earth's rotation speeds up. Just to put thi

There is this recent-ish paper (DOI: 10.1126/science.aba6630) on why it might be, that plants forego the peak of the solar spectrum. Essentially it boils down to being able to regulate the photochemistry of photosynthesis. If it were

It's not an X11 design flaw. The very concept of locking the screen is flawed. A flaw that also haunts Wayland, BTW. The concept of screen lockers is having a special layer, that can't be bypassed, which a locker creates. The whol

It's the perfect metaphor. Your brain is not a single cell. It's a couple billion. Every day in a healthy body a few million cells die, without any repercussions whatsoever.

They were using a so called accelerator mass spectrometer (AMS). The main challenge, as I understood it from talking with them, was in the chemistry required to prepare the samples for injection into the AMS. Specifically ensuring that ther

They did it, they finally did it! Context: I did my diploma thesis work at that lab, and shared the office with those guys. This is a result almost 10 years in the making. Congrats!

I'm aware of all of that. And yes, we're very synchronization dependent. However we also spent a lot of time tinkering with the launch parameter and properly interleaving all synchronization events and fences due to our demands

In those cases I prefer using Xpra, configured to use the regular Xorg server operating on the GPU. It would be nice if there was a X11 "media" extension to transport encoded image streams (aka video) with server side decoding int

Well, the semantics of what constitutes light and what not are a bit murky. CO2 lasers are still considered LIGHT amplification by stimulated emission of radiation. CO2 lasers operate at ~10000nm. In the optics community we usually consider
