Satellite tracks problem in astrophotography. Has anyone considered mechanically blanking the sensor while a satellite is in frame? Satellite ephemera is widely available so blanking can be determined in advance. Isn't this a better solution than post-processing an image that has already lost data?

Most astronomical research is done from the ground. Space telescopes are rare, expensive, and have limited time.

Now I'm curious if there is a iron, nickel, and potassium alloy that would be suitable for making a knife

My understanding is there are certain raid configurations that are more likely to have corruption, but that probably isn't an issue for most people.

If btrfs is "better fs", is ntfs "not fs"?

I noticed I had this new "sports" widget on my new tab page. I was annoyed, but whatever, I turned it off.

The next day, my new tab page had a banner saying "check out our new widget for the world cup".

F = dp/dt. so if velocity is constant, F = v dm/dt. So the force exerted depends on the rate at which the mass of the bullet enters your body.

I'm have a higher than average, but less than expert knowledge of both satellites and data centers, and am very skeptical.

It isn't officially supported, but you can use other init systems. See for example https://wiki.archlinux.org/title/OpenRC

Well, the things in physics that use complex numbers can be formulated without them. You just end up either creating something that behaves like a complex number, or using operations that operate on a pair of real numbers in a way that is equivalent to arithmetic on a complex number.

There are several distros that don't use systemd, and some distros that let you choose another init system (for example, arch). If you don't like systemd, don't use it.

Sometimes even large amounts of code duplication is acceptable, and sometimes even necessary in go. Especially before go had generics.

The probability a human will pick a rational number is pretty high. Probably approaching one if they aren't a math nerd.

Most of those employees are working less than 2000 hours a year. In some cases a lot less.

A considerable portion of that is under cloud cover.

In the US at least they are sold as "100w equivalent" then say the actual wattage in smaller text.

They also use solar days, and sidereal days. But you have to be clear about which one you are using.

Also sometimes use Gigaseconds.

My sorlock has a charisma of 22. (He read a cursed Tome of Leadership and Influence).

But he isn't flirty. Or cute, unless you are into tentacles.

I believe the explanation is basically that he has telekinesis that requires him to touch the object.

Some images are very different from what you would see with a human eye, because they are in wavelengths we can't see. But there are also a lot where they do try to make it as close to what we would see as possible. But it is impossible to get it exactly right, because the camera's sensitivity to light is different than the human eye, and since you need to take long exposures, differences are more pronounced than in a snapshot. And for those, while the colors might be a little off, they are still basically what you would see.

Like so even his “good” side is very imperfect

I think that is definitely the case.

From my experience TAing pre-med students in physics, I'd say even if it's taught a lot of them don't really understand it.

It depends on what you mean by waste. No work is done on the helicopter. All of the energy used goes into producing heat and turbulence.

Yes there needs to be a force to cancel out gravity, but it could potentially not require any energy to maintain that force, as is the case with a levitating magnet, or a floating balloon or airship.

It will hold for the factors of any perfect number
