A Smattering of Selenium #92

What’s that? Eight days in a row? That’s right…

• lolcommits seems almost funny enough to be a good idea
• A vision for Cucumber 2.0 is rather interesting
• Install Firefox on Amazon Linux X86_64 Compiling GTK+ is not something I have had to do. But then again, I haven’t tried.
• Nerrvana is yet another Selenium-As-A-Service provider. Looks like they are taking the ‘upload to our servers and run as a scheduled job’ approach rather than real-time.
• Ext JS 4.1 Performance is important stuff if you are using this toolkit. (I also like how they author is Nige “Animal” White — note that I did not add the animal part myself)
• Dunno if it is just who I follow of if the Ruby / PHP communities just don’t post this sort of thing, but How Callables Work is another geeky Python post
• Scaling CI at Etsy: Divide and Concur, Revisited is the lightsaber heuristic in action — only around Jenkins plugins this time.
• RSpec is not the reason your rails test suite is slow is a gist along the theme of ‘slow tests are slow but not for the reasons you think’
