I have a BSc in computer engineering and part of the major was just a couple of calculus and discrete math courses. I want to expand my knowledge in mathematics through online courses. Is there a specialized website that offers courses in various mathematics fields?

Ask HN: Which general programming language is good for learning/exploring math?
5 by mathpadawan | 2 comments on Hacker News.
Which general purpose programming language is good for learning and exploring math? Here is what I am looking for from the programming language: * Good standard library that helps in exploring math concepts. Python fits this bill. Python's standard library has functions like math.comb(), math.gcd(), math.factorial(), etc. that makes it easy to write down many closed-form expressions without reinventing the wheel. * Speed. If I am exploring a new concept and I want to test a conjecture for large numbers, such iterate-and-test loops in Python run 30 times slower than equivalent loops in C++. Here C/C++ fits the bill and Python does not. * Expressibility. While I am exploring mathematics, it should not feel like I am fighting the syntax of the language. Python and Java fit the bill due to their simplicity. C++ is manageable. Rust feels like too much work to hack some code together to test conjectures. * Longevity. The language should be stable and not prone to too many breaking changes. Some code I write now should run without modifications ten years later. C, C++, Go fit the bill. Python does not. * Open source implementations. The language must have popular free and open source implementations. I don't want to be paying large sums of money for something like MATLAB or Mathematica. Most languages popular here on Hacker News like Python, Go, Rust, etc. fit the bill. Now if there is no language that do not meet all the requirements above, that is fine. Something that comes to close to supporting most of the features above is going to be okay.

I think that in today’s world financial literacy is more important than ever to financial success in life and yet it seems like many kids graduating high school are financially illiterate. In my opinion everyone should a fundamental understanding of how a savings account, CD account, IRA, Roth IRA, 401(k) and MSA account work. Likewise, everyone should have a fundamental understanding of the equity markets, derivatives markets, futures markets, bond and treasury markets along with an understanding of how interest rates work and their effects on financial instruments like mortgages. Kids should be taught about the various forms of business structures available to them from starting a simple DBA to the numerous flavors of corporations out there. All this can be taught without giving financial advice, which may be more in the domain of parents, but by focusing on the theoretical and historical aspects of financial instruments so that kids have a better understanding of how they work and are better prepared for life in general.

Ask HN: Why are there no open source 2d printer?

In the 3D printing world, there are plenty of open source choices, allowing manufacturers to drive down costs. On the other hand, it seems 2d printing is stuck with legacy companies with completely closed drivers and hardware (you have to buy cartridges from the original manufacturer). Apart from the nozzle why is it hard to manufacture and/or design?
