alignas question is wierd 
Indeed, that global array is not good. You'll need to pass around an array, but you shouldn't do it with a C-style array. Doing that will cause it to decay to a pointer, which you should avoid in C++. If you have C++11, you could use std::array, which will be set at an initial size. But if yo...

I'm trying to use win32api to get mouse wheel input on windows MSDN.
I tried the following:
@state = Win32API.new('user32','DefWindowProc',['i'],'i')
p @state.call(0x0800)
But it keeps returning 0 no matter what I do with my mouse wheel.
I thought something is wrong with my mouse, so I trie...

I am using the GeoCompelte plugin with RequireJS
It works, but please could someone confirm I've done this correctly, mainly my understanding of shim:
requirejs.config({
waitSeconds: 120,
paths: {
async: './lib/async',
jquery: './lib/jquery-1.7.2.min',...
you need to escape the Percentage Symbol
the answer to this question should show you how to do it.
instead of doing that you could also create a query like this
SELECT * FROM HatTable
WHERE colorId LIKE '%10%'
this should give you all the options that have 10 in them.

folks.
Recently I've stumbled upon an interesting challenge for me.

Simple arithmetic:
return 7 - input + 5;
(which can be simplified as return 12 - input;)
Let's say the input is 7:
return 7 - 7 + 5 --> return 5
Or if the input is 5:
return 7 - 5 + 5 --> return 7

According to this meta question, tag-based syntax highlighting should be working but In this Lua question that was not the case. I suggested an edit to fix the highlighting in the question itself but you can still see the bad highlighting in this answer (the comments are the wrong color).
I asked this question on StackOverflow and in the comments someone had this to say.
In a proper design, you should almost never have to do a dynamic_cast, even if it's hidden inside some nice getter function.
Now this got me thinking.. a lot. I have been thinking of various ways in which I ...
