Sorting
-How fast can we sort
-It depends on model:)

the model is of what you can do with the elements

e.g
Quicksort       θ(nlgn)
Heapsort        θ(nlgn)
merge sort      θ(nlgn)
insertion sort  θ(n2)

so, can we do better than θ(nlgn)?

# Swift and Objective-C tweak supporting

With increment of swift, it's not ridiculous that using swift when you do some jailbreak development. If the tweak can get a better UI and I can code easier, there is no reason to refuse swift.

But one thing we should care about is that, Xcode 6 (and later) will link swift's dylib something like @rpath/libswiftDarwin.dylib.

That means if you didn't put those dylib files into a directory named Frameworks which right under your executable file's directory, it will just crash when you try to launch them. 继续阅读Swift and Objective-C tweak supporting

# Here's to the crazy ones

Here's to the crazy ones: the misfits, the rebels, the troublemakers, the round pegs in the square holes, the ones who see things differently.

They are not fond of rules. They have no respect of status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can't do, is ignore them, because they change things. They push human race forward.

Some may see them as the crazy ones. We see genius，because the people who are crazy enough to think they can change the world ... are the ones who do.
