Minimizing NExpectation for a custom distribution in Mathematica
...
As far as I see, the problem is (as you already wrote), that MeanResidualLife takes a long time to compute, even for a single evaluation. Now, the FindMinimum or similar functions try to find a minimum to the function. Finding a minimum requires either to set the first derivative of the function...
Why doesn't list have safe “get” method like dictionary?
...accessing list elements (as the len method is very fast). The .get method allows you to query the value associated with a name, not directly access the 37th item in the dictionary (which would be more like what you're asking of your list).

How to automatically generate N “distinct” colors?
I wrote the two methods below to automatically select N distinct colors. It works by defining a piecewise linear function on the RGB cube. The benefit of this is you can also get a progressive scale if that's what you want, but when N gets large the colors can start to look similar. I can also imagi...
Scala 2.8 breakOut
...breakOut itself. It is of type CanBuildFrom[Nothing,T,To]. We already know all these types, so we can determine that we need an implicit of type CanBuildFrom[Nothing,(Int,String),Map[Int,String]]. But is there such a definition?
