I think he's referring to the general idea that transistor fabrication size shrinking cannot last forever. Since atoms have a fixed physical size, if the shrinking continues indefinitely, at some point the "wires" in the tran

But isn't the mental energy required to come up with this answer (and judge its rude/nonrude status) already a distraction? Once you've left the bubble, there is a cost to coming back into the zone. In my experience it's

This is a pretty good reader: http://hckrnews.com/ Set to 25% if busy day at work, 50% for normal, and all if you want to waste lots of time. In either case, it takes away the need to check all the time because you might mi

Nice. The book seems like a good review of foundations. It's good to see the topic discussed by someone expert, because otherwise QM education is left in the hands of gurus and popular science who totally butcher the subject. See this

For a more "systems" approach for ODEs, you should look at Modelica: https://en.wikipedia.org/wiki/Modelica It's very powerful stuff.

Math and (theoretical) CS are pretty much the same — you will have a lot of mind expanding experiences and build up your theoretical toolset.

One possible cause is the pricing: Kindle strongly encourages you to price books at most 9.99 and a publisher might want to price their eBook higher (so as not to undercut the print version). Another reason is that it's not trivial to

I agree with the speaker that adding basic static types (Java/C/C++) is lot of work for not a lot of benefit. However advanced type systems like the one in Elm, now that's something else. Especially when refactoring and almos

There is also Copperhead OS in that space. It's pretty easy to install and it's supposed to be super secure: https://copperhead.co/android/docs/install I've been using for past couple of months, and

Probability theory and linear algebra are pretty much the core. Learning LA will help you become comfortable with multi-dimensional quantities, vector spaces, and give you some powerful computational techniques, e.g., SVG==PCA. Here is a sh

Very true. In many contexts (ancient, current, and new) the students are painted as an empty receptacle to be filled in with knowledge from some external source. In that world view, innovation is about "filling" students in a more

other projects in that space are: cython (need to manually do wrapping), xdress, SWIG, SIP, clif. Does anyone have experience with using these and able to compare/contrast? I'm afraid of C++, but if I can wrap it and learn how to

I think computer algebra systems can play a role in getting to grips on math. In particular SymPy has a very natural API, with the algebra verbs like "simplify", "expand", "factor", "solve", etc. Here

What about a format for code localization for code repos? A bit like a `.pot` file for string translation, but instead it applies to names. For reading code in another language, you apply the .pot file to the code base in a separate branch

good quote: "Why do so many pupils and students fail in mathematics, both at school and at universities? There are certainly many reasons, but we believe that motivation is a key factor. Mathematics is hard. It is abstract (that

Since we're guesstimating numbers a lot, it would be interesting to also guesstimate the human resources costs required to run the infrastructure: X electrical engineers, Y cooling engineers, Z SREs, W infrastructure devops ppls, etc.

Really nice course. Labs come with solutions and would make an excellent "challenge pack" for anyone learning Python and CS right now.

As a STEM person, I like the STEM-makes-you-a-hacker angle of this piece, but I think a more likely causation factor is the need for software piracy. Most computer users in Eastern Europe do not pay for Windows. They download a pre-cracked

For sure parents play a big role. The "forced practice" and colaboration with the teachers certainly are factors. I think a socio economic context also plays an important role. In an affluent family (as define by people who didn&#
