More #NoEstimates

agile-logo

Quite an interesting conversation and reaction to the #NoEstimates post. Good questions too, and frankly, to some I don’t have answers. I’ll try, anyway. Let’s start with classic project management.

Thymeleaf – fragments and angularjs router partial views

java-interview-questions-answers

One more of the many cool features of thymeleaf is the ability to render fragments of templates – I have found this to be an especially useful feature to use with AngularJs. AngularJS $routeProvider or AngularUI router can be configured to return partial views for different “paths”, using thymeleaf to return these partial views works really well. Consider a simple ...

scala-logo

We had a lengthy discussion recently during code review whether scala.Option.fold() is idiomatic and clever or maybe unreadable and tricky? Let’s first describe what the problem is. Option.fold does two things: maps a function f over Option‘s value (if any) or returns an alternative alt if it’s absent. Using simple pattern matching we can implement it as follows:     ...
