Four DB2 Code Bases?
Many years ago I worked on IBM DB2 and so I occasionally get the question, “how the heck could you folks possibly have four relational database management system code bases?” Some go on to argue that a single code base would have been much more efficient.

Index Investing Makes Markets and Economies More Efficient (2016)
U.S. equity index funds have grown dramatically in recent decades, from a negligible $500MM in assets in the early 1980s to a staggering $4T today.

Sattolo's algorithm provides a solution to this because it produces a permutation of a list with exactly one cycle, which guarantees that we will reach every…
