The Borg weren't prepared for a startship captain to lure them into his 50's noir detective holo-novel and then machine gun them to death with a weapon made out of hard light.

I always wondered if those episodes aired before or after the Stargate's SG-1 encounter with the replicators.

Nah, he would be surprised, not angry.

Does Kirk ever do that?

Great, now the background is overexposed and all the stars look like lines!

Because you may not have the chance to do it after?

We don't use absolute values in out outlets because there are no absolute values for voltage.

The line in your outlet oscillates between positive and negative (sqrt(2)*V) relative to the neutral, where V is the nominal voltage of your place. And because this is symmetric, you can also say that the neutral oscillates on the same range relative to the line.

You take some point of your circuit, call it "ground" and define the voltage there as 0.

If something has a higher voltage than it, than the voltage is positive. If the voltage is lower, than it's negative.

Also, you are mixing energy distribution names with your voltage references. Your ground wire has the same potential as the actual ground (the stuff made of dirt where your house is built). We usually define it as the ground in circuits that are connected to it, but you'll be surprised by how unusual it is to connect circuits to it.

But if voltage is electromotive force, how can it be negative?

The charge moves from higher to lower voltages. In a wire, that means that electrons move from lower to higher voltages. The absolute value of a voltage is meaningless, you will only ever use differences between them.

No. You become a radical only when you practice detachment.

I don't know what you are trying to say. But you can't predict the state something had before you observed it from the stuff you see.

That's the only way I managed to understand that phrase. It's an order and an observation.

Knowing current state of the univers, you can “predict” everything that has past

The observer effect is irreversible. Quantum mechanics is reversible only because the effect technically falls outside of the mechanics.

In related news, the entropy of a closed system is usually not constant.

Have you tried just walking slower?

In my experience, the only OS where printers won't have drivers is Windows.

But I don't deal often with dark demoniac systems, so there are probably lots of niche hellish devices that I don't know the details.

 

As a developer that learned it once, a long time ago, naturally I sign to the pledge...

I have some doubts if I should mark it NSFW.

 

All those student protests on the US seem to be about stopping their universities from supporting the Israel government. But supporting a foreign government is not a normal thing for a university to do, why do they do it?

Is there some educational or research resource they get?

 

The links like !NoStupidQuestions@lemmy.world.

I have had a pretty bad time making those work. I have tried searching for them at the communities page, and removing the exclamation mark and pasting them on my instance (lemmy.world/c/NoStupidQuestions@lemmy.world).

Some times one of those works, other times my instance finds nothing. And if I go directly to the home instance of the community, it doesn't bring my login.

What is the recommended way to use those?
