Wiki is a single-page application for browsing and editing content distributed throughout a federation of similar creative-commons licensed sites. What is a federated wiki, and why does federation matter? Authors throughout the federation pull content towards themselves as they edit. With this package authors publish their own edits back to the federation as they edit.

This package is not supported in the same sense that my other packages are, but since it is such a fun playground, I am very open to contributions, suggestions, and bug fixes. I just can't put this project at the top of my priority list the way I can/do the others, so it may take me longer to get to than normal.

zenprofiler helps answer WHAT is being called the most. spy_on helps answer WHERE those calls are being made. ZenProfiler provides a faster version of the standard library ruby profiler. It is otherwise pretty much the same as before. spy_on provides a clean way to redefine a bottleneck method so you can account for and aggregate all the calls to it. % ruby -Ilib bin/zenprofile misc/factorial.rb 50000 Total time = 3.056884 Total time = 2.390000 total self self total % time seconds seconds calls ms/call ms/call name 50.70 1.64 1.64 50000 0.03 0.05 Integer#downto 19.63 2.27 0.63 200000 0.00 0.00 Fixnum#* 14.19 2.73 0.46 50000 0.01 0.05 Factorial#factorial 9.93 3.05 0.32 1 320.36 3047.10 Range#each 5.54 3.23 0.18 2 89.40 178.79 ZenProfiler#start_hook Once you know that Integer#downto takes 50% of the entire run, you can use spy_on to find it.
