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

I have one SSID with pihole (which I use), and one without. Works pretty well, if you’re ok with a VLAN-aware network.

Ah, good point!

Dell XPS 13 Snapdragon seems like it’s trying to compete with the Air.

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.

I recently started using voice (SSB) on the HF ham bands, and have made contacts on 15, 17, 20, and 40m. No real DX, but made one foreign contact ~1000mi away and another domestic ~2000mi away.

I live in a city and it’s challenging to get a good antenna setup, so it’s always a compromise where I am.

Nothing very impressive by ham standards, but it’s fun.

“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?

I’m not mad at the huge amount I pay in taxes. I’m mad about what I get in return.

You know you fucked up real good when Mr. Oatmeal gets involved.

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.

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.

IIRC chvt is a privileged command, which makes sense (if an unprivileged user could execute this command they could effectively brick the computer for a local user).

That said, my understanding is that modern DE’s are given a lot of access, so presumably chvt is allowed (and in this case, is required because as others mentioned, password is required). So the only other option is to fail unlocked, which is all kinds of Bad.

And over twice the GDP.

“Wow you signed the document in blood, you must be really hardcore.”

“No I’m just cheap.”

That’s…pretty believable.

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.
