This is a hard question to answer without knowing what types of problems your hacker friends like to solve. For example, quadcopters tend to cater to certain types of problems (mapping, precise control, etc), while fixed-wing aircraft tend

Purposefully? No, but I'll admit that during undergrad I mistakenly obfuscated code. We were competing in the Intelligent Ground Vehicle Competition (igvc.org), but I didn't really understand the "meat" of the problem

I suspect that we agree more than disagree. What I meant was that we implement capitalism to generally get abundance of things like food and medicine that we consider good for society (to the point of calling them "goods"), but t

I'd argue that it's not a startup (maybe a charity or a hobby instead) if you're not trying to monetize. Whether sex is the ultimate motivation behind human affairs is something I'll leave to the Freudian psychologists.

While there is some overlap in terms of the mechanics, I would personally refrain from taking this analogy too far. The point behind capitalism is the assumption that people are motivated by money but that the profit motive can be channele

I wrote a little Python program that lets you try it with an arbitrary integer. It assumes that for instances where you have to lay out a zero that you need one bit (for 0). This times out quickly if you use too big of a number, but you ca

Let's try your algorithm with the number 25 (11001 in binary). One formulation is 2(11)+3. The primes up to 25 are 2,3,5,7,11,13,17,19,23, so we'll use the index 4 to represent the prime number 11. To lay this out, we need to rep
