Is there a shorter way to require a file located in the same directory (as the script being executed)? require File.expand_path(File.dirname(__FILE__) + '/some_other_script') I read that require "my_script" and require "./my_script" will actually load the script twice (ruby will not recognize that it is actually the same script), and ...

[for those not following along at home, this is the sequel to Rolling My Own Version Control ;)] So i gave in and installed TortoiseSVN (to work with a friend on a project, my personal version control is alive, well, and working as i want it). Having never seriously used one of these before, can someone give me (a link to a) concise exp...
I have a method that returns the past x days and it currently does the following: var dates = new List<DateTime>(); for (int i = 0; i < numDays; i++) { dates.Add(DateTime.Today.AddDays(-i)); } return dates; I feel like there should be a more compact way of doing this, perhaps using LINQ. Suggestions? Also, if I do keep it the ...
In python, one can use printf like formatting with the "%" operator: "i am %d years old" % 99 or "%s is %d years old" % ("bob", 101) Is there a way to get the same concise syntax in Ocaml, for arbitrary numbers of arguments? For a single argument, the following works: let (%) = Printf.sprintf in ... "i am %d years old" % 99 Is ...
Is there a more syntactically concise way of writing the following? gen = (i for i in xrange(10)) index = 5 for i, v in enumerate(gen): if i is index: return v It seems almost natural that a generator should have a gen[index] expression, that acts as a list, but is functionally identical to the above code. ...

To make my code more concise, can I do something like int f(int const x, y, z), g(int const x, y, z); to declare functions f and g which each take three int const arguments? Edit: Perhaps here is a better example: int f(int const a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z); How would that not be m...
If you have a boolean variable: boolean myBool = true; I could get the inverse of this with an if/else clause: if (myBool == true) myBool = false; else myBool = true; Is there a more concise way to do this? ...
