Spring Boot gets Big Props

Spring Boot, the open source Java application framework, got big props this week with Netflix's announcement that it will migrate its Java production environment from its custom-made application infrastructure to Spring Boot! 😮

Most popular GitHub programming languages in 2018

Interesting! 😀 See GitHub's blog post concerning the most popular programming languages for GitHub projects in 2018.

Registering Oracle Java using alternatives on CentOS 6

If you want to add the Oracle JDK to a CentOS 6 box, one easy way is to download the JDK RPM package, and use the rpm(8) command to install it easily, like this:

$ sudo rpm -ivh jdk-7u45-linux-i586.rpm

But chances are the newly installed JDK will not be visible at the command line, especially if the openjdk is already present. How to fix this? You'll have to use the alternatives(8) command to manually register the Oracle JDK. See the instructions on the if-not-true-then-false site for details. I recommend following the "Use Java JDK latest version" example.

Java 7 vulnerability

Here's the U.S. DHS advisory concerning the Java 7 security issue, along with the steps to take to address it. Interestingly, this basic information has been missing from most of the media reporting I've seen.

Getting Sun Java and Groovy Working on CentOS 5.3

I had a devil of a time getting Sun Java, Groovy, and the GraphicsRenderer class working on CentOS 5.3. Furthermore, Google searches for tips on the Internet failed to turn up any directly relevant results.

Therefore, by research, trial and error, I came up with this simple method which WORKS:

1. Download the Sun Java JDK RPM and install it.
2. Download the unofficial Groovy binary RPM from Codehaus.org and install it.
3. Download the GraphicsBuilder module from Codehaus, too.
4. Unzip GraphicsBuilder in /tmp.
5. export GROOVY_HOME=/usr/share/groovy
6. Drop all the GraphicsBuilder jar files into $GROOVY_HOME/lib.
7. Copy or move the GraphicsBuilder bin directory to $GROOVY_HOME.
8. Add the following lines to your .bashrc:

# Java setup for CentOS

export GROOVY_HOME=/usr/share/groovy
export JAVA="sun"
export JPATH="/usr/java/default"
export JAVA_HOME="$JPATH"
export CLASSPATH="$JPATH/lib:/usr/share/groovy/lib"

*THEN* make sure you add /usr/java/default/bin BEFORE /usr/bin in the shell PATH!

NOW you can use groovy from a bash command prompt (at last!)

JMeter - A very handy tool

I suppose some techies will laff when they read this, but I'm getting a first-time intro to JMeter and it's COOL! It's an open source tool, from Apache, which allows the test engineer to codify HTTP and other protocol requests, issue them to a test server, save the responses, and validate them vs. one or more assertions. Since it's written in Java, it runs on Windows or Linux nicely, too.

The UI is a little clunky and you have to make sure to Save your configuration changes before starting a run (it doesn't prompt you to do so), but it provides a lot of testing capability and flexibility.

New inflection trends

I've noticed some growing inflection trends - perhaps you have, too:

1. Rich Internet Application (RIA) websites - Popping up all over the web. Many new services are offering more content, context search and interfaces, more appealing and flexible presentations, etc. See My Yahoo, Yelp, Scribd, and RedBubble as examples - there are many more out there, too.


2. New object oriented languages that offer comprehensive web and OS integrations. For example, Ruby on Rails, Ramaze, etc., Visual Studio .NET, Java, and C++.


3. New simple but comprehensive configuration management tools: Atlassian, Git, SVN, etc.
   
4. New web development and testing tools. Far too many to list here - it's tough to keep up with everything that's appearing they're coming out so fast!


5. New interface APIs: Android, Yahoo! BluePrint, Palm Mojo, iPhone SDK, etc.


6. New cloud computing virtual servers and storage, making it easier to stage and test on the open Internet: Aptana Cloud, Amazon EC2, Amazon S3, and Zetta.

Despite the economy, it's a great time to be a developer or a tester :)
