I had a question about the veritasium video, at some point they say that the electrons barely move, that confused me since that doesn't match my understanding of amperage, flow of electrons being for example 6.24x10^18 per second.
Anyone care to help me out? Maybe that just isn't much?
Calculate the volume of wire that would contain 6e18 free electrons, assuming 1 electron per atom.
You can intuit it by knowing Avogadro's constant is 6e23.
So 1e-5 mol, 1 mol of (atomic) Copper is 63g, so that's 6e-4g of copper. Density of copper is 9g/cm3 so let's say 1e-4 cm3 = 1e-1 mm3 = 0.1 cubic mm of copper.
So one amp in a copper wire is equivalent to 0.1 cubic mm of that wire's electrons flowing out each second. I'd say that's "barely moving".
Just to validate then, these barely moving electrons will create a field that induces a current on the electrons on the other side of the wire that is 1m away, which would turn on the bulb, that if the lightbulb was an ideal current detector that ignores all other sources of electric fields?
I don't disagree with a lot of your above reply, but this part in particular picked my interest, mostly because I don't understand how its not racist.
> They aren't saying "this man is unable to perform this role due to his race" in a racist-against-this-person way, they're putting additional structural checks in place as a preventative measure.
Its not about the intention of the emitter, its about the receiving end of it.
It seems that if we flip this so that the receiving end is part of a minority we would all think this is utterly racist independent of the intention, how is it not?
From your example the only thing that happened is that now you hold x euros and Kraken holds x amount of USDT.
Unless Kraken goes to Tether org and asks "hey I got these USDTs, please give me the USD" no redemption has occurred.
That some people can in effect transact USDT for fiat via other mechanisms (like your example above) says nothing about Tether org backing or reserves.
Until you go to Tether org with your USDT's and ask them for USD you won't know if they have the reserves.
The reason tether stays at $1 is because the tether org or their delegates buy or sell to keep it there. They have to or the whole thing would become untethered as it were.
I really don't like chord like shortcuts, while ctrl and [ are positioned in a way you don't have to contort your hand it kind of requires you to move away from the hjkl row or stretch your pinkies. Consider mapping esc to jk (as a sequence) it works surprisingly well.
inoremap jk <esc>
and
inoremap <esc> <nop>
so that you never use esc again
not having chord like shortcuts was one of the main reasons that led me to try vim over emacs in the beginning, so I kind of think they're "anti" vim.
We built our own hardware to control and interface with vending machines, doing what the Web 2.0 did for Web. We’re truly full-stack so you can expect to see Hardware/Firmware/IoT/Mobile/Web/Backend/Cellular/Bluetooth and others.
Firmware and embedded engineer
- Experience in Linux based embedded systems in production
- Experience in C/C++ based development
- Experience with Linux kernel driver development (highly desired)
- Experience with high-level programming language development such as Python (desired)
- Experience with Linux BSP creation (desired)
- Experience with buildroot and/or yocto build systems (desired)
What we have is a Linux based embedded system that also has a hard real-time processing component. The suitable candidate feels comfortable working with Linux platform with core components written in C, but the application architecture also utilizes high-level language components to provide the overall service and speed up the development. Has confidence in participating in low level debugging (logic analyzer etc), core dump analyzing of application failures and also general configuration matters of Linux.
We’re looking for go-getters that enjoy taking ownership over problems and seeing them driven to a solution, atm we prefer more experienced candidates to pave the way.
You can reach me hugo at mytenten dot com, this position doesn't require Japanese.

Yep - and in the town I used to live in Japan there were yearly festivals showcasing various immigrant (or even visitor's) culture. All amateurs, just getting together to create something from their various home countries and doing a performance. And then a nice party afterwards, with everybody (audience and participants). And there are food festivals too.
Your problem with Vim is that you don't grok vi. [0]
I agree with you that if you don't use a specialist tool 24/7 you'll be slow, but that is expected vi optimizes for expert users not for novice users.
In the same way that if I don't use Photoshop and then just want to do something simple in it, it's going to take me a lot of time and am probably going to forget how to do it because I don't use it enough.
That does indeed seem to be the reason. As the article states it: "[T]he Krukenberg procedure's poor cosmesis makes it very rare [...]"
I'm sure self-image is a complicated consideration when someone is dealing with an amputation, I can't imagine trying to assess what the right choice for another person would be in that kind of situation. But surgeons straight out refusing to perform it seems extreme, based on the limited information provided in the article.
Making that assessment is a part of the surgeon's job.
Perhaps they realized at some point that many patients are enthusiastic for the procedure before it's done, but most grow to hate it afterwards -- and blame the surgeon for having done the procedure to them.
Any given patient will have had zero prior experience with complex physiological and psychological post-operative outcomes, whereas surgeons do (individually or collectively.) It seems fitting that they should share that, and discourage patients from having procedures if outcomes are mainly bad.
I doubt this is that good for the joints in the elbow, as the two bones normally hinge in parallel. Patient self-image seems to be the main reason though.
I imagine the reason is side effects, like additional long-term pain for the patient, compared to having to just a stump. As far as I know, those things are hard to predict (and mitigate if present).
But I'm by no means an expert, that's just a semi-educated guess.
