Pin pitch means how tiny the physical pins in the connector can be spaced apart.

IR drop losses happen because a wire has resistance, it isn't a perfect conductor. 28AWG wire has about 0.22ohm/m. Given a 2 meter cable, you might expect to see 0.44ohm one-way. Current is also travelling back, so the circuit "sees" another 0.44ohm. That's a total of 0.88ohm

A wire will cause voltage drop following ohm's law. V=I/*R. So for 1A of current, you will see 0.88V lost.

Say you're trying to charge at 15W (5V 3A), your phone is only going to 'see' 2.36 volts, and 7.9W are wasted in the cable.

For a 100W device (20V, 5A), 4.4V are lost, also meaning 22W are wasted.

The concentration of them is rising exponentially, that's the part that terrifies me.

It's possible we just haven't crossed a threshold yet.

And formula fed

They're everywhere, i'm not sure that's even physically possible.

How much of the issue is the system vs the students?

When I was in school, I remember dealing with hours of homework on top of extracurriculars and eventually working a job.

My choices were do homework or sleep. Either way I lost. So I definitely used chegg so I could get sleep and not fail.

I think our expectations for kids are just... not realistic? And I think that fuels a lot of the resentment for school.

So, middle school

before is the really important one

I'm with you, it's so fucked. And every time we lose manufacturing, we lose everything else. Engineering, sourcing, quality, follows manufacturing.

Ya because the tarriffs mean that a device already sold LOSES money to fulfil. Medical devices already don't have great margins...

How much electricity was wasted for you to post, and us to receive, your human slop

You could think of LLMs as a glorified 'magic 8 ball', since that's about as much 'understanding' it has.

FYI, St John's wart can affect serotonin, which can be dangerous if you're on anti depressants.

What makes the kernel such a PITA?

Bro mocking the unstable guy holding a gun for being chicken sounds like a good way to get shot

Oh i'm sure it will

Like actually?

If we're making fun of him for chickening out, he's def going to double down.

Microwave point-to-point radios are fastest because they travel through air, but more importantly, are typically the shortest path possible by line-of-sight.

Being 66.7% of speed of light doesn't matter terribly when you consider that the cable path is shorter by more than 66.7% of path taken by satelite link.

Wait really? Butterworth is more like honey than maple syrup?

I guess butterworth is just flavored HFCS.
