How to find encoding of a file via script on Linux?
...
Sounds like you're looking for enca. It can guess and even convert between encodings. Just look at the man page.
Or, failing that, use file -i (linux) or file -I (osx). That will output MIME-type information for the file, which will also include the character-s...
How to find all links / pages on a website
Is it possible to find all the pages and links on ANY given website? I'd like to enter a URL and produce a directory tree of all links from that site?

C/C++ include header file order
...
I don't think there's a recommended order, as long as it compiles! What's annoying is when some headers require other headers to be included first... That's a problem with the headers themselves, not with the order of includes.
My personal preference is to go from local to glob...
How to create circle with Bézier curves?
...e using Bezier curves.
To complete the other answers : for Bezier curve with n segments the optimal distance to the control points, in the sense that the middle of the curve lies on the circle itself, is (4/3)*tan(pi/(2n)).
So for 4 points it is (4/3)*tan(pi/8) = 4*(sqrt(2)-1)/3 = 0.5522847498...
Please explain some of Paul Graham's points on Lisp
...list seem the most interesting and still relevant now.
To understand them, it is useful to have a clear picture of what happens with Lisp code -- in the form of a stream of characters typed in by the programmer -- on its way to being executed. Let's use a concrete example:

Initializing multiple variables to the same value in Java
...
String one, two, three;
one = two = three = "";
This should work with immutable objects. It doesn't make any sense for mutable objects for example:
Person firstPerson, secondPerson, thirdPerson;
firstPerson = secondPerson = thirdPerson = new Person();
All the variables would be pointing ...
What does a lazy val do?
...
The difference between them is, that a val is executed when it is defined whereas a lazy val is executed when it is accessed the first time.
scala> val x = { println("x"); 15 }
x
x: Int = 15
scala> lazy val y = { println("y"); 13 }
y: Int = <lazy>
scala> x

Error: “Cannot modify the return value” c#
...erty you're accessing a copy of the value held by the class, not the value itself as you would with a reference type (class), so if you set the X property on it then you're setting the property on the copy and then discarding it, leaving the original value unchanged. This probably isn't what you int...
