How to Compare Flags in C#?
...al times and got ~500ms for HasFlags and ~32ms for bitwise. While still an order of magnitude faster with bitwise, HasFlags was an order of magnitude down from your test. (Ran the test on a 2.5GHz Core i3 and .NET 4.5)

Fast permutation -> number -> permutation mapping algorithms
...be very small. This can "easily" be reduced to O(nlogn) though, through an order statistics tree (pine.cs.yale.edu/pinewiki/OrderStatisticsTree), i.e. a red-black tree which initially will contains the values 0, 1, 2, ..., n-1, and each node contains the number of descendants below it. With this, on...
How can I exclude all “permission denied” messages from “find”?
...files_and_folders | grep -v 'Permission denied' >&2

Should I use Java's String.format() if performance is important?
... Another poorly implemented micro-benchmark. How do both methods scale by orders of magnitude. How about using, 100, 1000, 10000, 1000000, operations. If you only run one test, on one order of magnitude, on a application that isn't running on an isolated core; there's no way to tell how much of the...
How is the fork/join framework better than a thread pool?
...ypical FJ usage cuts the problem into tiny pieces. Doing these in a random order requires much co-ordination at a hardware level. The overheads would be a killer. In FJ, tasks are put onto a queue that the thread reads off in Last In First Out order (LIFO/stack), and work stealing (in core work, gen...
