...nto the calculation engine was in the form of vectors and matrices. Higher order functions eat these for breakfast with minimal fuss, minimal code. Beautiful. Lack of bugs Functional programming can feel strange. I can be working on an algorithm, trying hard to get the code to pass the type checker...

...he commonly used definitions, quicksort is unstable - that is the original ordering of two objects is not preserved, if they are equal during this sort. Having an unstable sort algorithm means that you have to come up with all sorts of 'magic' to sensibly sort data with multiple criteria, rather tha...

...t;mutex> and <atomic> headers, and in particular with std::memory_order. I'm not sure if it covers all possible memory semantics achievable, but it just might. The more subtle semantics are particularly relevant in the context of lock free data structures, which can offer performance benef...

... +1 It is by this simple understanding that I always remember in what order the combination comes. Even today we can still see this mechanical logic in any inktjet-printer (I love to understand since I hate to learn). My other memory-tricks are: "mac? Return to sender" and "NewLineFeed" (to re...

...he documentation states that "Composite keys are sorted by lexicographical order, i.e. sorting is performed by the first key, then the second key if the first one is equal, etc". Does this mean that the structure is stored such that a lookup for a specific 2-part composite key will take O(n=1) time,...
