The drama of the Healthcare.gov Ad Hoc team is now a modern tech fable: a small cadre of young geeks from Silicon Valley and President Obama’s election campaign parachute into the federal bureaucracy to rescue the site and exceed the goal of eight million insured households.

Git v2.0.0 is a backward-incompatible release, which means you should expect differences since the v1.x series. Unless you've been following closely the Git mailing list, you probably don't know th...

For the 5th time, ZeroTurnaround's tech detectives at RebelLabs revisit the tools & technologies landscape in Java, collecting data, crunching numbers and see

After demonstrating modern Java code in part 1, and exploring deployment, management, monitoring and benchmarking of JVM applications in part 2, it is time to delve into modern Java web development.

import static spark.Spark.*; import spark.*; public class HelloWorld { public static void main(String[] args) { get("/hello", (request, response) -> { return "Hello World!"; }); } }

In part 2 we go beyond the code to explore some of the tools that give the JVM its power

Despite it assosiation with large, bureacratic, and slow enterprise shops, and big, unwieldy frameworks, recent additions to the Java language, tooling, and libraries, combined with more lean programming styles, have turned programming Java into a rather pleasant experience.

Running the Docker Registry

Command string for running the Docker Registry as a container. A volume has been mapped to /tmp/registry in the container which is the default location for the registry to write data to (mapped to /vagrant/registry). Environment variables are also set to tell the registry which config file and environment config to use.

docker run -name registry_instance -d -p 5000:5000 -e SETTINGS_FLAVOR=dev -e DOCKER_REGISTRY_CONFIG=/docker-registry/config.yml -v /vagrant/registry:/tmp/registry registry

WebLogic 12c JNDI Problem with Spring 3

Just wanted to put this out there so nobody else will have to go through debugging this.

Here is the situation: Spring 3 app deployed to WebLogic 12c that does a JNDI lookup for a Datasource. The Datasource is a Spring bean annotated like:

@Bean public DataSource datasource() { // do jndi lookup }

The app deploys fine the first time (assuming JNDI JDBC resource exists). You want to post a new build so you undeploy and redeploy... and the app doesn't start because the DataSource doesn't exist in the JNDI tree (it does show up in the WebLogic Admin Console though). How did it disappear from the JNDI tree?

Apparently when you undeploy the application, the Spring container will start cleaning up its beans. Since the DataSource bean is annotated with ONLY @Bean, it will try to call a close() or shutdown() cleanup method via reflection if possible. This is how the DataSource disappears from the JNDI tree, it finds a cleanup method which causes the DataSource to remove itself from the JNDI tree.

The workaround is specifying an empty destroyMethod on the annotation so it doesn't use its automatic "inferred" mode default."

@Bean(destroyMethod=""") public DataSource datasource() { // do jndi lookup }

Haven't Been Updating Lately

I have had the initial proof of concept application complete so I've switched gears to learning Linux sysadmin stuff, Vagrant, Docker, Puppet, buzzwords, etc. I'll be posting those samples soon.

Useful AngularJS Account Registration Form Directives

An example of two directives for custom validation that I wrote for an account registration page. The validateUnique directive is used to validate the uniqueness of the username and the validateSameValueAs directive is used to validate two password fields. Direct link to code on gist.
