JVM Notebook: Basic Clojure, Java and JVM Language performance

"Measure, don't guess. The primary goal of all performance tuning exercises should be maximize the end user experience given the resource constraints." [1] "It isn't so much a "farewell to the J" as an expansion of the platform opportunities Java provides. Sun's investment to power ongoing development of JRuby and Jython broadens the range and reach of Java, as a whole." -- Rick Ross Overview and JVM Languages    One of the exciting trends to recently emerge from the Java community is the concept of the JVM language. These technologies are all that you would expect them to be. They are implementations of languages that run on the Java Virtual Machine. Some are newly created and some are based on existing, more mature languages. JRuby, Jython are two JVM languages based on CRuby and CPython. Groovy, Scala, Clojure are three completely new JVM languages that were created to add new language features that weren't supported by the core Ja...

On Unit Testing, Java TDD for developers to write

It has been a while, let's kick off 2017 with a blog entry. I have read and I am reading about four or five posts a day about unit testing. It really has been a long time obsession for me. I have moved past the technical and practical considerations on unit testing frameworks and done with the debates with "should you use Junit or Mockito or Karma?" I am more interested in the psychology of unit testing, who does it, likes it, hates it? It really is one of those easy to learn, hard to master concepts. For example, many many may play chess when they are young and can end up being horribly chess players most of their life, I am part of that majority. Unfortunately, I have never played chess and sat down for hours and tried to master it. I never see the common patterns or have a developed end game. I mostly just play with a knowledge of the basic rules. Following good unit testing practices within your software development shop is a lot like playing chess. It is easy to le...

Wolfram's Cellular Automata, A New Kind of Science and Example Squaring Rule (2)

Overview - Playing the Game Of Life When most computer users upload a profile image from their desktop to Facebook's website they don't stop to think about the simple binary math rules that are fundamental to most digital devices. We realize that 4 gigabytes of RAM is more memory than 512 megabytes but we don't visualize the logic chips that are involved in an xor $0x100, eax operation for a 32-bit CISC processor. Software developers have to consider memory management or how a computer's operating system loads their programs into memory. They don't normally consider VHDL logic circuit designs, the data paths, arithmetic logic units or the millions of transistors that make up a modern CPU. Those low-level details have been intentionally hidden from the user application developer. The modern CPU may have changed dramatically over the last decade but at the heart of early digital computing were simple Boolean operations. These simple rules were combined togeth...
