I think mplayer has an ASCII output mode (VLC, too?), and I believe youtube-dl can output to stdout.

The rest is, as they say, left as an exercise to the reader.

Sounds like he was a mantis and was posting while copulating.

No love for us Dvorak users :(

Sounds like it was a 2 petawatt pulsed laser, with picosecond pulses, so 2kJ/pulse. Staggering amount of power and energy for a pulsed laser!

Note that it’s not CW, so the average power will be much, much, much less than the pulsed power. Too lazy to find the rep rate to see average power.

TIL, thanks! Edited my earlier comment.

Yeah, the only thing I could imagine would be that image loading/processing uses an optimized library, but a single color is (unlikely but possibly) implemented poorly as a loop over every pixel, with some egregious overhead.

Most likely shit post though… See reply, apparently real!

Oh I wasn’t complaining, I was making a bad joke (the cartoon is a stalemate).

One of the coolest parts of The Expanse IMHO was that The Mormons commissioned a giant space ship, and it didn’t feel forced or far-fetched.

Ugh, Lemmy is full of stale content.

(Edit: it’s a joke. Stalemate/stale content…I chuckled at, and upvoted, the post.)

In my experience, the blue (405nm) lasers pointers can far, far exceed the nominal (5mW?) power.

“Necessary, but not sufficient” sums up the role of a degree for a lot of jobs.

Remind me again, what color was Obama’s scandalous suit?

You can turn it off, at least for ext4: https://lwn.net/Articles/784041/

Although you can use case insensitive filesystems with Linux, and case sensitive filesystems with macOS. I believe the case sensitivity is a function of the specific filesystem — but yeah, practically, the root for Linux is always case sensitive, and APFS ain’t is only if you ask it to be ( https://support.apple.com/lv-lv/guide/disk-utility/dsku19ed921c/mac ).

No, that’s not really a useful way of modeling it for the case of light traveling through a linear medium.

The absorption/re-emission model implicitly localizes the photons, which is problematic — think about it in an uncertainty principle (or diffraction limit) picture: it implies that the momentum is highly uncertain, which means that the light would get absorbed but re-emitted in every direction, which doesn’t happen. So instead you can make arguments about it being a delocalized photon and being absorbed and re-emitted coherently across the material, but this isn’t really the same thing as the “ping pong balls stopping and starting again” model.

Another problem is to ask why the light doesn’t change color in a (linear) medium — because if it’s getting absorbed and re-emitted, and is not hitting a nice absorption line, why wouldn’t it change energy by exchanging with the environment/other degrees of freedom? (The answer is it does do this — it’s called Raman scattering, but that is generally a very weak effect.)

The absorption/emission picture does work for things like fluorescence. But Maxwell’s equations, the Schrödinger equation, QED — these are wave equations.

I kinda assumed any Mars mission would include some simple centrifugal pod. Seems like even if it’s just for sleeping it would be useful.

Dispersion and nonlinearities would like to have a word ;)

I’d like to know more.

In all seriousness though, I thought it had some aspects of good, which was odd given that it’s satirical commentary on fascism. For instance, gender didn’t really matter and women were promoted, and while the shower scene was meant to show how fascism castrates the masses (or something like that, iirc), I thought it was a relatively wholesome scene, all things considered.

While neat, this is not self-sustaining — it’s taking more energy to power it than you’re getting out of it. (You can build a fusion device on your garage if you’re so inclined, though obviously this is much neater than that!)

One viewpoint is that we’ll never get clean energy from these devices, not because they won’t work, but because you get a lot of neutrons out of these devices. And what do we do with neutrons? We either bash them into lead and heat stuff up (boring and not a lot of energy), or we use them to breed fissile material, which is a lot more energetically favorable. So basically, the economically sound thing to do is to use your fusion reactor to power your relatively conventional fission reactor. Which is still way better than fossil fuels IMHO, so that’s something.
