Another way to solve Sudoku is to understand that it is an instance of the Exact Cover problem [1]. Basically, solving a 3x3 Sudoku grid is nothing more than finding 9 "sheets" of each number which superimpose exactly on top of th

When I started using quaternions for rotations, which -- if we're honest -- is the #1 practical applications, I had much more success building my intuition around this Wikipedia section: https://en.wikipedia.org/wiki&#x

Nice job! I like the idea and the implementation. A not-so-minor nitpick though: I have a decent recent laptop yet the Solar System book takes forever to load on Firefox (29s including 25s where the whole UI thread is blocked.) Maybe some k

In my case it came in two steps: 1. Learn GoF design patterns. Be amazed by the cleverness. 2. While learning others languages, discover that other approaches remove the need for GoF design patterns at all. Example: Visitor isn't neede

Indeed. Personally I'm used to think in functional ways: map, fold, function composition, immutability... I'd like to be good at Haskell but I'm always having lots of pain dealing with it, because I never see the end of the l

Before Rust, it could be said that Haskell has the same philosophy of ensuring almost everything works at compile-time. Anyway, I hope for a future where programmers will be able to specify all contracts, invariants, etc. in code, and hav

I personally prefer the Rust documentation as a comprehensive reference than the cover-to-cover design of a book such as The C++ Programming Language. (As much as I prefer cppreference.com rather than Stroustrup's book.) The Rust book

It seems very ironic that C++ adds more rules to the language in order to get less cluttered code. This "..." syntax, which probably won't be used a lot of times, will be nice because you'll understand intuitively wh

And if you ever want to learn C++ later (C++11 specifically), you'll have a big chunk of the work already done. Rust's move semantics are very helpful to understand C++ smart pointers, for example. Also, lambdas/closures. You

I'm honestly surprised to all the comments in here. This is not my experience at all. I thought I may share my perspective. I'm currently pursuing a PhD program here in France. This is a special kind of PhD, called "CIFRE&quo

No, I don't think MetaMath is the kind of thing the OP wants. Sure, it builds mathematics from "first principles", but not in the same meaning as the OP means. When you read his question, "first principles" really m

Just a comment about the buttons: It feels weird that they kinda "pre-press" themselves when hovering. I guess ergonomically speaking, a button shouldn't move down while it's not pressed. On the other hand, maybe a glow

I guess most meters have a display accurracy of 1 mg/dL, but that's just on display. If you check your blood twice in a row, you're likely to get at least a 5 mg/dL difference. I'm not even sure this is your meter&#

Effective Java and Effective C++ have a good format for listing best practices, and nowadays more and more languages seem to adopt their own "Effective" book or web page... I like how useful they are to see real-world problems bef
