What Haskell representation is recommended for 2D, unboxed pixel arrays with millions of pixels?
...utorial on the use of repa, which is a good place to start if you already know Haskell arrays, or the vector library. The key stepping stone is the use of shape types instead of simple index types, to address multidimensional indices (and even stencils).

Legality of COW std::string implementation in C++11

Now here's why your version did not work:
You probably thought that this might work because if User had a has_many relation to Shop, @user.shops.create(params[:shop]) would work. However there is a big difference between has...
Git - Pushing code to two remotes [duplicate]
...riginal/repo.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
Now, if you want to push to two or more repositories using a single command, you may create a new remote named all (as suggested by @Adam Nelson in comments), or keep using the origin, though the latter name is less descripti...
Use of .apply() with 'new' operator. Is this possible?

var s = new (Function.prototype.bind.call(Something, null, a, b, c));
var s = new (Function.pro...
Why are elementwise additions much faster in separate loops than in a combined loop?
...'ll notice both loops are faster. Furthermore, the second (double) loop is now the slower one as you would normally expect.
As @Stephen Cannon points out in the comments, there is a very likely possibility that this alignment causes false aliasing in the load/store units or the cache. I Googled ar...
