Hi samerbuna, jsComplete is very nice. The multi-panel interface is pretty intuitive and the COMMAND+ENTER to re-run the code works well too. One thing about the speed control. You should consider making it a [-|spped|+] button rather than

I have a nice "life hack" which I use to keep entertained while doing dishes or cooking: I make the computer read to me HN articles (not all of them... god no!), but the select few long reads that seem interesting. I select the te

In case anyone is wondering, this is the specific formula: def KincaidGradeLevel(syllables, words, sentences): return 11.8*(syllables/words) + 0.39*((words/sentences)) - 15.59

Check out this short tutorial on mechanics with calculus that I've written. It would make a good first introduction to physics[1]. There is another one for linear algebra[2]. In general I think programmers shouldn't fear the math

Learning coding takes five years—at least. Do you really want to invest this time? Like several other commenters have said, a better approach would be to learn coding on your own time. (Choose a language—any language will do, learn the basi

That's very cool. I've been thinking about "detailed" prerequisite structures (e.g. [1]) for a long time, but I never thought about connecting with occupations/jobs/competencies. In addition to replacing resume

SymPy, being Python, gets it wrong... but if you use S = sympify to transform the long numbers into SymPy objects it works: S('9999999999999999.0') - S('9999999999999998.0') 1.0

Hi Nic, no rules against self-posting as long as it's interesting articles like yours and not just self promotion. I know a bit about quantum computing too so I did a high-level fact checking of your post without finding any bugs. Impr

The "compute the eigenvalues of Matrix([[1,1],[1,0]]) raised to the power N" approach to computing the Nth Fibonacci number is only constant time if you assume exponentiation is constant time, which it is not on any computer or re

I think of algebra as a meta-math skill since it allows you to manipulate, simplify, or otherwise make use of structure in mathematical expressions. The most important rule is the "do the same operation on both sides of the equation&q

That's like the coolest thing ever. Seriously, if you can grow vegetables and legumes at scale w/o tapping groundwater it would be an amazing development.

I like this uses the filesystem for the website structure. It reminds me a bit of dokuwiki. Very usable + easy to understand compared to configuring routes.

Is 25 TFLOPS a lot? How big of a cluster would you need to achieve this level of scientific computing "at home"? cf. a modern GPU which can do 5000-8000 GFLOPS

Not bad. I like the screenshots + videos approach. Really hand-holdy which can be good for someone starting out. Wordpress is probably the best choice for beginners to get a presence on the web, but the MySQL configuration could be an issue

You should also consider SymPy, available as a webapp http://live.sympy.org/ or in jupyter notebook form. Plotting function graphs is a bit harder (matplotlib) but overall I find SymPy to be much more logical and easy to gr

I think linear algebra is a much more valuable and general-purpose math tool. I'm not sure how feasible it would be to teach linear algebra topics "properly" to high schoolers, but even a half-assed linear algebra would be mo
