What goes into your .gitignore if you're using CocoaPods?
...
@fatuhoku For Cocoapods-blind continuous-integration test servers, in my experience. I check it all in because I don't have access to the build script for my CI host (business rule) and treat CocoaPods as a developer tool, not a build system or package manager.

What is tail recursion?
...essentially equivalent. The order of the if/then and style of the limiting test...if x == 0 versus if(i<=n)...is not something to get hung up on. The point is that each iteration passes its result to the next.

Why use 'git rm' to remove a file instead of 'rm'?
...there are reasons to go the OS route. E.g. if you need to delete a file to test that something works before committing the change, the OS route is a bit safer than using git rm, as in the git case you have to unstage the action, whereas in the OS option you just have to fetch (I believe).

What is the difference between .text, .value, and .value2?

Javascript AES encryption [closed]
...ek; it's called "slow AES" because it's not implemented in C++. But in my tests it was not impractically slow.
It lacks an ECB mode. Also lacks a CTR mode, although you could build one pretty easily given an ECB mode, I guess.
It is solely focused on encryption. A nice complementary class that do...
