I dont. I'm not defending FTDI's actions w/r/t their driver, just pointing out that ftdi does currently fill the market niche of "reliable, good usb-serial devices", and while I'd love for someone else to

Not even close. Everyone and their brother has a "vision" for what it will look like, but back in the real world there is nothing solid.

That's simply false. What is true is that per-band allocations tend to be larger at higher passband frequencies, but the width of the baseband in absolute terms is what determines information capacity. See: The Shannon limit

How reliable is the documentation for the ch340g? I don't have experience with Olimex directly, and for production designs I'm wary of datasheets that are translated this poorly -- while they frequently are just fine, i've ru

Assuming you pay someone to maintain it, maybe. Which costs a lot more than a github/bitbucket contract.

Mendeley or Zotero's tagging might work well for this. Both are more commonly used for organizing bibliographies in science, but should work here as well.

...5 GHz WiFi is more than capable of going through walls. In fact, 802.11ac has significant improvements to multipath rejection, meaning it should perform better in environments with many reflections than the protocols that offer 2.4GHz op

Sunlight is ionizing radiation -- the ultraviolet light is capable of knocking electrons off their atoms, damaging nearby biological systems. 2.4 GHz radio waves cannot do this; absorption just causes local heating (in this case, truly infi

Important to remember, especially if you're practicing physics or engineering in any form: models are not the real world. You're (kind of) right about the (typical interpretation of) the models we use for entanglement, but open qu

GSL is closer to something like BLAS or LAPACK[1] -- it's a library that provides tested/reliable/optimized implementations of commonly used functions in scientific computing. The other software you listed is more user facing

I don't like the use of soft/fuzzy for certain fields, but I do know what it means in this context: it's shorthand for "fields so complicated that we aren't even sure if the questions we're asking mean anything

For posts, I'm not sure what the algorithm is (I think it's deliberately more complicated, and has to take into account time of posting?), but after this article [the op] was written, reddit implemented the method for comments, as

So I think you're confused between: (a) Experimental predictions of QM calculations (b) Interpretations of why you're performing those calculations In particular, things like collapse of the wave-function (for example) present som

Chris Fuchs' writings are pretty good: http://perimeterinstitute.ca/personal/cfuchs/ I mentioned this in another comment, but I particularly like "Quantum Mechanics as Quantum Information, Mostly"

Yeah, no, Chris Fuchs is definitely not doing pseudoscience. Please don't make judgements like that based on popular science writeups (though, this is actually one of the better ones I've seen on interpretations of QM, even if the

Adjunct definitely means something different at MIT. For instance, departments are only allowed to hire adjuncts up to 5% of the total normal faculty members of their department[1]. MIT EECS only has six [2]. In effect, this means that adju

Thank you so much for this; you just described my undergraduate experience in physics perfectly, especially the endless nagging feeling that something isn't quite right -- I never managed to make that feeling go away. I ended up taking

Actually, that's an interpretation of quantum mechanics, not quantum mechanics itself. QM itself is in fact a statistical theory: the result of a calculation is a probability distribution of possible outcomes (even in the cases where

Not at all to disagree, but just to clarify: drink less alcohol, drink lots more water. Minor dehydration is amazingly common and you'll be astounded how much better you feel if you force yourself to drink large amounts of water regu
