“A good unit test should fail for only one reason” – this simple fact is oh so important to adhere to and has a major impact on the quality of your design. When I’m writing a test and I’m unable to identify a single and clear responsibility for that test – broadening the test is never a good answer. Instead – this is a clear code smell to tell me that I need to work on my design.
A quick intro to Hibernate – before anything else, it’s good to have a solid grasp on the basics.

Probably the biggest news this week – if you’re doing any kind of work involving HTTP: the old HTTP spec is now OBSOLETE and replaced with 6 separate specs. 5 years in the making (or is it 7?) – I am excited about this. On to HTTP/2.0.
And a quick recap of the changes that were introduced with the new HTTP spec.
The more grasp you have over what happens on the network, the better off you’ll be understanding the overall behavior of your system, and the better chance you’ll have to find the low handing performance optimization fruit. And don’t think the isn’t any – there usually is.
An interesting read on how log data is used to identify performance issues – the kind of insights that you can only get from large amounts of data across many applications.
Reg-Green-Refactor – it’s a message that has been discussed over and over (and over) again; this is a quick and solid intro to the question – But Why Red?
