Handling the Edge-Case Search-Space Explosion: A Case for Randomized Testing
For much of software testing the traditional quiver of unit, integration and system testing suffices. Your inputs typically have a main case and a small set of well understood edge cases you can cover. But: periodically, we come upon software problems where the range of acceptable inputs and the number of potential code paths is simply too large to have an acceptable degree of confidence in correctness of a software unit (be it a function, module, or entire system).

3 Tips for Writing Performant Scala
07.23.2012 | Posted by Russell
Here at Sumo Logic we write a lot of Scala code. We also have a lot of data, so some of our code has to go really, really fast. While Scala allows us to write correct, clear code quickly, it can be challenging to ensure that you are getting the best performance possible.
Two expressions which seem to be equivalent in terms of performance can behave radically differently. Only with an in-depth understanding the implementation of the language and the standard library can one predict which will be faster.
