implicit val doubleFormat = new Printable[Double] { override def asString(value: Double) = value.toString } } And finally, the main app using our library. There are two example functions doing operations on different types, so it's not possible to supply single specific implicitPrinter[T]as...
What would happen if we did not have to explicitly pass parameters to a function? If the function understood them by context? Or if we did not have to call a function explicitly and the compiler understood that by the context in which we are? Would we want to use it? That is the con...

I then reverted to the original DSP and looked at the outputted HTML. Based on that I updated the DSP like this. [xml]<% atg.servlet.DynamoHttpServletRequest dreq = atg.servlet.ServletUtil.getCurrentRequest(); %> <a href="javascript:poptastic(‘foo.jsp?_DARGS=/betweengo/test.jsp_AF...
Usually non-serializable stuff is created on each executor. E.g. consider these examples: // this fails when you call an "action" on myrdd2valmyNonSerializableObj =newThread();valmyrdd2 = myrdd.map( elem => myNonSerializableObj.toString() +"-"+ elem )// this worksvalmy...
