  • It’s a collection, kind of like Array.
  • Store in form of object’s hash.
  • Unordered.
  • Has standard collection methods: Add, Remove, Contains.
  • Faster in term of performance, compare to List.
  • No access by index. Thus, most┬ámethods take in <T> as parameter.

Bubble Sort Algorithm

A simple sorting algorithm that works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted.

Software Laws

I was looking for a specific theorem called CAP theorem, but came across these interesting, sort of funny but somewhat true, software laws.

I think these laws are useful to get better understanding of philosophy behind a software or computer science in general.

  • Atwood’s Law

    Any software that can be written in JavaScript will eventually be written in JavaScript.

  • Brooks’s Law

    Adding manpower to a late software project makes it later.

  • Conway’s law

    Any piece of software reflects the organizational structure that produced it.

  • Miller’s law

    To understand what another person is saying, you must assume that it is true and try to imagine what it could be true of.

  • Wirth’s law

    Software gets slower faster than hardware gets faster.
