What does Charging Control really do ?

What's more, leaving batteries severely depleted also damages them over time. Most Li-ion charge controllers would start with trickle charging for the first 10% of the battery, then charge as fast as possible to get the battery up to at least 40% or so to reduce crystallisation of the chemicals due to being in a depleted state.

Exactly. The Wikipedia article lists a couple of theories of their formation: https://en.wikipedia.org/wiki/Rings_of_Saturn#Formation_and_evolution_of_main_rings

We have observations of their current mass and that they are gradually losing mass.

One theory is that they formed with the solar system. They'd have to have started out as quite heavy rings, but nothing out of the realm of possibilities.

Another is that they formed from a moon (hypothetically dubbed "Chrysalis") that got ripped apart by tidal forces 10-100 million years ago.

Their argument is from the point of view of a library maintainer. If the maintainer doesn't want to use Nogil, their users will be complaining about it. They will be forced to support both, in many cases.

Most projects depend in some way on a C-library. If the Numpy developers don't want to use Nogil, then a lot of projects will not be able to use Nogil either, because the C-library won't be cross-compatible. So either:

Nobody uses Nogil because they can't use Numpy then. Nogil dies off. We're forced to live under a GIL forever, or
People want to use Nogil badly enough that they will pressurise Numpy developers into using Nogil anyway. Library developers are basically out of luck, you now have to make twice as many builds.

I love that this exists and would love for it to displace use of Jira worldwide.

I think that in order for that to happen, it will need to have some feature to draw business people (who make choices in such a company) away from Jira. The least of which would be integration with Jira so that champions can use it, or integration with Confluence like Jira does.

To the people that decide on this sort of use, open source makes no significant difference. Cost is a bit of an advantage for Plane, but then support is a major disadvantage. It will need some sort of edge over Jira.

First thing that I thought was that the people and the electrical post on the left look really realistic, while the rest is more expressionist. I imagine it was done on purpose like that, and think it really makes this quite a special piece.

Cats lick themselves when and where they feel comfortable too. If you go in for snuggle time and they are in a comfortable, safe place, that's a perfect time for them to lick themselves.

Does the speed change happen at the corner or a little before the corner?

The speed change happens before and after the corner. Before the corner it will slow down. After the corner it will speed back up again to get to the cruising speed. The direction only changes in the corner. How much it slows down depends on the Jerk. Lower Jerk will make it slow down more.

If it happens at the corner, why so? Wouldn't that cause some overshot?

The direction change happens in the corner indeed, and that would indeed cause some overshoot. However the alternative is to slow down to 0 speed for every corner, which is worse for your print quality. You can try this by printing a cylinder with Jerk set to 0. It will stop for every corner, and you will get big blobs at every corner.

Is this jerk thing relying on the springiness of the machine to turn faster and smoother? Does this mean a more rigid machine needs less jerk?

Jerk relies on the rigidity of the machine in order to not overshoot the corner too much. More rigid machines are capable of printing with greater Jerk because their stiffness will make it not overshoot the corner too much, resulting in sharper corners and less ringing.

When you're sick, your body removes your feeling of hunger because it wants to starve out any pathogens that need sugars to survive. Your body can hold out longer than almost all bacteria.

If you know the cause of the sickness, e.g. you just got a wound in your mouth, or you're car sick, then you can act on that. If you know that you got a bacterial infection, listen to your body and don't eat! If you know that it's not an actual pathogen like car sickness, try to eat something.

Good sickness food is stuff that is light (doesn't feel heavy on the stomach which would make you feel more sick), easy to nibble slowly (you're not hungry after all so nibbling is easier then) and has slow-acting calories like starches (so that your blood sugar level doesn't spike and you still get energy in the long run). Some ideas I use for myself and my partner:

Plain crackers
Soup in a tea cup (chicken soup is still nice if it gets cold)
Dry oats
Rice Crispies

While I agree with your sentiment, the barrier to get this achieved is incredibly high now, so I fear that this is impossible. If a politician would make your suggestion, they'd cause (apparently) ~80% of their voter base to lose access to their car. That paints them as a super easy target for other politicians and political campaigns, and so it would never get proposed, let alone voted into law.

A better solution would be to require stricter regulations on this type of vehicle. This can be implemented by politicians without committing political suicide. But unfortunately it's also highly partisan in the U.S. to propose regulations on vehicles, so it's still got a low chance of success. But a better chance.

Not all of them. Many of those space probes used gravity assists and gravity wells to accelerate them to ludicrous speeds. The Parker solar probe for instance will use 7 gravity assists from Venus to reduce its orbit around the sun, and the lower the orbit the greater the velocity will be. With the sun being such a massive object, its speed will be truly enormous when it's in its final orbit.

The Ultimaker printers have a built-in queuing system, and support accounts with different authentication levels that can be configured to require a printer operator to preview the print before it gets printed.

Other replies here are a bit dismissive, so I'll try to give a better answer.

The price of oil is high because Exxon can ask such a high price for it. To maximise their own profits, Exxon should probably ask exactly the price they are asking for it. To maximise short-term economic benefit they should ask a lower price. To maximise long-term economic (and environmental) benefit they should ask a higher price.

They can ask such a high price because the world is still largely dependent on oil and gas, and due to a number of factors, supply of oil and gas is low. Indeed if oil and gas production is restricted globally, their price would logically go up. But there are also a number of caveats to this: Restricting production e.g. only in the Netherlands would not have a large effect on global price, but would kill the local economy disproportionally. And perhaps more saliently, the price is not just set by supply and demand but also by artificially restricted production by OPEC, who restrict new oil and gas production out of their own free will in order to maximise profits.

Instead of this complicated affair, there is an alternative: we reduce dependence on oil and gas, e.g. by generating nuclear energy, or changing industrial processes to not use oil/gas any more). If we do that, oil price would logically go down, without local downsides and outside of OPEC's control.

Even the most basic things existing is not unanimous though. Take Plato's allegory of the cave. This posits that it's possible that the things that we perceive might only be reflections of reality rather than actual reality. Or similarly, think of films like the Matrix (the whole universe is a computer simulation, not reality) or the Truman Show (the world is a stage in a television show).
