> Don't you need the defects to have semi conductors? No. However, most of the time you want doped semiconductors and doing that introduces defects. The defects are bad for resistive losses but that's life. > every computer

Of course it is! And the explanation isn't even too quantum. Heat induces atoms to vibrate, these vibrations mess up with the perfectly periodic potential that you would have at 0 K and induces electron scattering which leads to more e

> resistance sucks and makes your electrons bump into protons This is a myth with little bearing to reality. Protons (and the atomic nucleus) are insignificantly tiny when compared to the size of an atom. The major contributor to electri

I'm sorry. Now that I know it bum's me too to not have reached for the pun :(

I would have never thought my humble blog would end up in the front page of HN! Please be merciful :)

I'm not a lawyer of course, but I don't think it's as simple as saying you signed it. You could give up your right to any form of holidays or accept to offer your first born in case of default on a contract but those clauses

Unfortunately, for certain people in certain situations even this won't do it.

Saying he doesn't want to produce any code that has bugs is not the same as doing it. Given how accomplished he is I'm sure he is well aware that sometimes bugs slip through.

Fastmail can generate random@fastmail.com email addresses that go straight to your mailbox. Really useful for throaway accounts and low value services. It apparently has an integration with 1password but I can't vouch for it as I haven

For me at least it's not that simple. My weight (healthy to low BMI) has been very stable over many years with vastly different amounts of exercising and quality of eating habits within that period. Fat to muscle ratio does move but to

This worked for me too. However, I re-enabled them after and everything was good again.

The example is not great. I wouldn't blame the use of averages there, but rather not realizing that when the cost of excess/spoil is not symmetrical the optimal answer in terms of minimizing average cost is not going to be the for

This reminds me of the fuzzy simplical sets used by UMAP. Is there any relationship between the two? Could it be used to accelerate the algorithm?

It's not so clear cut to me. The same number can decode to completely different pieces of information. In fact one can build a concrete mapping such that a specific number maps to any piece of information. Does that make all numbers il

Same thing! I had played the piece 5 minutes before the lesson and right after the lesson warmup (I warmup before the lesson so that my teacher thinks I'm better than I really am...ego..self denial...whatever) he asks for the piece and

Narrow and long strips of graphene are called nanoribbons in the literature. When they start to get really narrow their properties change significantly [1]. [1] https://www.nature.com/articles/ncomms10177 Edit: spellin

I'm currently using a non-linear version of it, DeepSURV [*], implemented in pycox for a predictive maintenance job. They are much more informative than a binary label and give space to make a business decicision as to how close to EOL
