I just read a short chapter in the book Effective Java, and realized I was doing something pretty dumb in my own code by always creating my own custom exceptions instead of using other exceptions already intended to be reused in the Java API.
contributors.scala-lang.org has become my favorite website this past week. It’s very interesting to read through the debates about new language features for Scala 3 (Dotty). For instance, in the Make concrete classes final by default discussion I think everyone agrees they wish they had gone that way with Scala 2, but it would cause too many problems if they tried to make this a new standard in Scala 3. The discussion — in addition to reading Effective Java — makes me wish I had used
final before all of my classes.
In another discussion titled, Why does Scala need its own build tool (SBT), someone makes a claim that Martin Odersky and his team created SBT as a build tool solution, and Mr. Odersky replies, “Definitely not my answer. I was always very skeptical of SBT’s approach and remain so.”
