I have gone through different questions/articles on m>Me m>ssage Brokers and ESBs(Even on stackoverflow). Still not a clue as what is the CLEAR demarcating difference between an m>Me m>ssage Broker and an ESB? Now here I am trying to compare products, Websphere Broker and Mule ESB!!

Simultaneously m>me m>rge multiple data.fram>me m>s in a list
I have a list of many data.fram>me m>s that I want to m>me m>rge. The issue here is that each data.fram>me m> differs in terms of the number of rows and columns, but they all share the key variables (which I've called "var1" and "var2" in the code below). If the data.fram>me m>s were identical in terms of columns, ...
When to use Storyboard and when to use XIBs

JIT compilation is a tricky balancing act between not spending too much tim>me m> doing the compilation phase (thus slowing down short lived applications considerably) vs. not doing enough analysis to keep the application competitive in the long term with a standard ahead-of-tim>me m> compilation.

What is the difference between currying and partial application?

Currying is converting a single function of n argum>me m>nts into n functions with a single argum>me m>nt each. Given the following function:
function f(x,y,z) { z(x(y));}
When curried, becom>me m>s:
function f(x) { lambda(y) { lambda(z) { z(x(y)); } } }
