There's an iPad app called "The Particles". Last update was in 2013 though.

Last time I benchmarked Puma on MRI 1.9 and 2.0 it was quite fast for most requests, but some requests took more than 20 seconds to complete. The bottom line being that it would be nice to see full ab output.

MixPanel's Split Test calculator supports multiple groups, but doesn't have anything visual:

They use two-proportion z-test.

I wrote about hardware change issue and a couple of related issues a while ago: http://www.rotanovs.com/cloud/amazon-ec2-failures/

Also, to clarify, hardware change occurs when you stop an instance (which frees it, so it can be taken by another customer), and then start a new one using the same EBS volumes.

Only first two chapters ("Strategies in problem solving" and "Examples in number theory") are available for free, so I took the second one as a title because it has some brilliant strategies.

Works fine in Chrome 14.0.835.163/Mac OS 10.7.1.

Keyboard shortcuts are inconsistent in Ubuntu.

On Mac, Cmd-C always means Copy (even in Google Docs), and Ctrl-C does what it should in Terminal. Compare that to Gnome's use of Ctrl-C in all apps except for terminal, where you have to press 3 keys (Ctrl-Shift-C) at once.

Go to line is Ctrl-G, Ctrl-L, and Ctrl-I in different editors.
