Worst case if the string is large and (almost) entirely made up of repeated delimiters (&), it could allocate 12-24x the original size of the string due to object overheads in .Net. I would go with the second approach, and if that's not fast enough then w...

I've been reading about the bare and non-bare / default repositores in Git. I haven't been able to understand quite well (theoretically) about the differences between them, and why I should "push" to a bare repository. Here's the deal:

Spring AOP vs AspectJ
...LTW (load-time weaving) or the AspectJ compiler.
It uses the Proxy pattern and the Decorator

Aspects aren't applied when calling another method within the same class.
There can be a little...
