Significant Software Development Developments of 2016

This post is my personal and opinionated assessment of some of the most significant developments related to software development in 2016.

As with these previous years’ assessments, this assessment of 2016’s major developments ...

Compare Exactly in Java Equals Methods

As I’ve worked with legacy Java code over the years, I’ve run into subtle logic and performance issues that could be traced back to improperly overridden Object.equals(Object) methods. Although the concept behind the “equals” method is seemingly simple, Josh Bloch points out in Effective Java that “Overriding the equals method seems simple, but there are many ways to get it ...

Bash on Windows 10

Because I work with Linux and Windows based machines for development, I often find myself wishing that I had some of the handy command-line Linux tools available in my Windows environments. Cygwin, PowerShell, and custom Groovy scripts written to emulate Linux tools have helped, but I was pleasantly surprised to recently learn that Bash on Ubuntu on Windows 10 is ...

Inheriting Javadoc Method Comments

Although the JDK Tools and Utilities pages for the javadoc tool describe the rules of Javadoc method comment reuse by implementing and inheriting methods, it is easy to unnecessarily explicitly describe comment inheritance with [email protected]} when it’s not really needed because the same comments would be implicitly inherited. The Java 8 javadoc tool page describes the rules of inherited method ...

Fixed-Point and Floating-Point: Two Things That Don’t Go Well Together

One of the more challenging aspects of software development can be dealing with floating-point numbers. David Goldberg‘s 1991 Computing Surveys paper What Every Computer Scientist Should Know About Floating-Point Arithmetic is a recognized classic treatise on this subject. This paper not only provides an in-depth look at how floating-point arithmetic is implemented in most programming languages and computer systems, but ...

Salaries and Job Offerings Categorized by Programming Language

The Paysa Blog recently featured a post Silicon Valley’s Most Valuable Skills in which they looked at the most valuable software development skills in the United States in terms of average salary and in terms of job openings listing the skill. Of particular interest to me was the portion of the post on programming languages and how average salaries and ...

The Value in Project Valhalla

I have been interested in the progress of Project Valhalla for quite a while, but Brian Goetz‘s recent message “Project Valhalla: Goals” has raised my level of interest. I have frequently enjoyed Goetz‘s writing because he combines two characteristics I want most in a technical author: he knows the subjects he writes about much more deeply than what he is ...

Unintentionally Obfuscated: Dealing with Challenging Legacy Code

I recently had to deal with some legacy code with significant performance issues. It was more challenging than I thought it should have been to fix the issues and I was reminded throughout the process of how relatively simple good practices could have made the code easier to fix and might have even helped avoid the troublesome code from being ...

JavaOne 2016 Observations by Proxy

I was not able to attend JavaOne 2016 and so am happy to see numerous resources online that allow me to make observations based on JavaOne 2016 content. I reference and briefly describe some of these JavaOne 2016 resources in this post and add some of my own observations based on use of those resources. These resources are useful to ...

Painful Reminder of Java Date Nuances

I don’t need to use java.util.Date much anymore these days, but recently chose to do so and was reminded of the pain of using the APIs associated with Java Date. In this post, I look at a couple of the somewhat surprising API expectations of the deprecated parameterized Date constructor that accepts six integers. In 2016, Java developers are probably ...
