Android set height and width of Custom view programmatically
...e programatically like that :
graphView.setLayoutParams(new LayoutParams(width, height));
This is fine if you know the exact size of the view. However, if you want a more flexible approach, you can override the onMeasure() method to measure the view more precisely depending on the space available...

Heh, I was just writing this. Didn't think about tuple_element though, thanks.

Suppressing “is never used” and “is never assigned to” warnings in C#
...gma warning restore 0649
To find such warning numbers yourself (ie. how did I know to use 0169 and 0649), you do this:
Compile the code as normal, this will add some warnings to your error list in Visual Studio
Switch to the Output window, and the Build output, and hunt for the same warnings

C++ auto keyword. Why is it magic?
...learn C++, auto has always been a weird storage duration specifier that didn't serve any purpose. But just recently, I encountered code that used it as a type name in and of itself. Out of curiosity I tried it, and it assumes the type of whatever I happen to assign to it!

When and why would you seal a class?
...security class's definition? Even if the answer would be "yes", this would ideally be a compiler option i.e. "generate optimized code for all non-sealed classes", rather than having us developers to alter code base.

Why would iterating over a List be faster than indexing through it?
...complexity is effectively O(N^2) just to traverse the list!
If instead I did this:
for(String s: list) {
System.out.println(s);
}
then what happens is this:
head -> print head -> item1 -> print item1 -> item2 -> print item2 etc.
all in a single traversal, which is O(N).
No...
Small Haskell program compiled with GHC into huge binary
...e dynamically linked! All the Haskell libraries are copied in verbatim.
Aside: since this is a graphics-intensive app, I'd definitely compile with ghc -O2
There's two things you can do.
Stripping symbols
An easy solution: strip the binary:
$ strip A
$ du -hs A
5.8M A
Strip discards symbols...
Does PostgreSQL support “accent insensitive” collations?

Among other things, it provides the function unaccent() you can use with your example (where LIKE seems not needed).
SELECT *

WHERE unaccent(name) = unaccent('João');

How to pass a class type as a function parameter
... I'm making a button. In that button's code (it's SpriteKit, so inside touchesBegan) I want the button to call a Class function, so need a reference to that class. So in the Button Class I have created a variable to hold a reference to the Class. But I can't get it to hold a Class, or the Ty...
