In theory JSON Schema could serve this purpose, but in practice I am not sure it does. Worth mentioning I hope. Other than this, my personal opinion is that since JSON is predominantly used for transferring objects, documenting equivalent objects in language client uses (Java, C#, various scripting languages) may make most sense — after … Read more
There’re differences among www, www/ and www/*. Basically from the documentation and my own tests, www find a match with a file or a directory, www/ only matches a directory, while www/* matches directories and files inside www. I’ll only discuss on the differences between www/ and www/* here, since the differences between www and … Read more
Literals that start with 0x are hexadecimal integers. (base 16) The number 0x6400 is 25600. 6 * 16^3 + 4 * 16^2 = 25600 For an example including letters (also used in hexadecimal notation where A = 10, B = 11 … F = 15) The number 0x6BF0 is 27632. 6 * 16^3 + 11 … Read more
First let’s understand what big O, big Theta and big Omega are. They are all sets of functions. Big O is giving upper asymptotic bound, while big Omega is giving a lower bound. Big Theta gives both. Everything that is Ө(f(n)) is also O(f(n)), but not the other way around. T(n) is said to be … Read more
Short explanation: If an algorithm is of Θ(g(n)), it means that the running time of the algorithm as n (input size) gets larger is proportional to g(n). If an algorithm is of O(g(n)), it means that the running time of the algorithm as n gets larger is at most proportional to g(n). Normally, even when … Read more
%w(foo bar) is a shortcut for [“foo”, “bar”]. Meaning it’s a notation to write an array of strings separated by spaces instead of commas and without quotes around them. You can find a list of ways of writing literals in zenspider’s quickref.
