Resources for learning system design.

I'm interviewing with google and palantir and have others queued in case these two reject me. One topic they ask about which I'm not quite comfortable with is system design. By system design I mean mostly two things: - object -oriented - UML sketching type of questions, often quite abstract like &qu...

Re: Probabilities in QM

When we say that the domain is {2 tails, 2 heads, 1 each}, are we using that as a shorthand for a function on {HH, HT, TH, TT} where f(HT)=f(TH), or are we actually talking about a function defined on only 3 values? Either representation is ok. What matters physically is the fact that the constrain...

Re: Cool games on the interweb redux

Here's a puzzle game I made:

it's about programming and has robots in it. If you liked manufactoria, you will probably like this one too.

Re: Probabilities in QM

You heard correctly. Unfortunately it is hard to explain satisfactorily (i.e. by reducing to some other well established facts) because this is a very basic postulate in QM - it doesn't follow from anything else in QM. To get a deeper understanding of this postulate one has to resort to Quantum Fiel...

Re: Continuity of consciousness in a computer

I feel you did not respond to my main argument, I'll restate it in a shorter way: the whole set of questions about continuity and human consciousness would make exactly the same amount of sense if you would substitute "a tennis ball" for "a human" and "roundness" for &q...

Re: Continuity of consciousness in a computer

1. Polish SF writer Stanislaw Lem pondered pretty much the same set of questions in (among others) his short story "Dialogs" - published in 1957. You can find it on his official website - google "Lem dialogs". Although I don't agree with the conlclusion expressed in the last para...

Re: Creation of Scientific Equations

In theoretical physics at least, equations almost always go before mesurements. There's a couple of reasons - one is - you have to first have a pretty good model of a phenomenon to make sensible measurements on it. For example you cannot just stare at the terabytes of output of the LHC detectors - w...

Re: Thoughts on dark energy

In addition to the wrong state equation (relation between energy density and universe expansion), standing electromagnetic waves have another more obvious problem as a candidate for dark energy- they are not dark. Even though standing waves from the era of the early universe would by now be redshift...
