Let’s encrypt for www and non-www

I enabled letsencrypt for brie.com today. Turns out for www and non-www, you have to give it the -d option for the www.brie.com and the -d option for the non-www domain. It works now for both. Yay for letsencrypt.

As root, do the following on Debian Squeeze.

# certbot --authenticator standalone --installer apache \
 -d brie.com -d www.brie.com --pre-hook "service apache2 stop" --post-hook "service apache2 start"

Madbomber2 development using SDL2

I have been working on redeveloping Bill Kendrick’s Madbomber game so that it runs on Android. Bill originally wrote Madbomber back in 1999 in SDL1. When I bought the Android Nexus 7 tablet, I thought that it would be a good platform for running madbomber as it has become a popular game platform. SDL2 now supports Android, so I have been rewriting it for SDL2. I also made the source so that it uses autoconf, so that it will check for proper libraries. I haven’t done a full release of the Android version of the game, but once I do the release of the Android game, I will publish the source for the Android. It’s actually the same source, put you just have to put into the Android build framework. Check out Madbomber2 sources.

Cereal Hack Raffle Application

Willow Schlanger and I participated in the Cereal Hack this last weekend. We built a Raffle application. We both worked in parallel. Willow built a version in PHP and I did mine in Java. Willow’s app was the most functional in the time for our 3 minute presentation. We didn’t win any awards, but our presentation went well. I continued to work on my Java version. You can download my Java version at the following link:

raffle08.zip is the version at the time of this writing.

I hope to put a link to Willow’s code soon.

Running JBoss Application Server

This is about the JBoss Application Server, commonly known as JBoss AS. I have some posts that need the JBoss application server. If you visit the JBoss website, you will notice many projects that fall under it. Make sure you look for the application server.

Download JBoss AS server from the download site. http://www.jboss.org

GNU/Linux
http://download.jboss.org/jbossas/7.1/jboss-as-7.1.1.Final/jboss-as-7.1.1.Final.tar.gz

or

Windows
http://download.jboss.org/jbossas/7.1/jboss-as-7.1.1.Final/jboss-as-7.1.1.Final.zip

Unzip or untar it.

GNU/Linux

some_path$ tar zxf jboss-as-7.1.1.Final.tar.gz

Windows

c:\some_path> unzip jboss-as-7.1.1.Final.zip

Note the path where you started it. If you are using Maven from a different window, set the JBOSS_HOME to it in a different console. Replace <some_path> with the actual value.

Linux

 set JBOSS_HOME=<some_path>

Windows

 $ export JBOSS_HOME=<some_path>

After downloading it, change to the bin directory and start it as follows:

GNU/Linux

$ cd bin
$ ./standalone

Windows

c:\some_path> cd bin
c:\some_path\bin> standalone.bat

JBoss AS should start. Go to your web browser and check it out. http://localhost:8080

Maven

I have some projects that use Maven. Here are the steps to get maven. Go to the Maven website. There is Maven 2 and Maven 3. Get the Maven 3 download. The name of the download is the following:

apache-maven-3.0.4-bin.tar.gz

If you are using Windows, you can download the version with the zip extension. Download it and unpack it on your local drive. Now add it to your path.

  • Linux (bash)
    export PATH=<Maven_home_directory>/bin
  • Windows
    set PATH=<Maven_home_directory>/bin;%path%

Now test it with the following command:

mvn -version

You should see version output similar to the following:

brian@rt13:~$ mvn -version
Apache Maven 3.0.4 (r1232337; 2012-01-17 00:44:56-0800)
Maven home: /home/brian/pkg/apache-maven-3.0.4
Java version: 1.6.0_18, vendor: Sun Microsystems Inc.
Java home: /usr/lib/jvm/java-6-openjdk/jre
Default locale: en_US, platform encoding: UTF-8

You now have Maven working.

Changed comment policy

In order to comment, you have to be registered now. I thought the re-Captcha would cut out spam comments, but either there are good re-Captcha crackers out there, or a lot of people looking for trackback links. I am assuming trackback is the correct term. I am also not sure if WordPress is protecting against cross site scripting attacks as it seems to allow all html characters.

I have still been hacking a lot of Java EE stuff and I hope to post more.

Some code would be nice!

We shall see if this turns to code.

Using Flex SDK on Linux

I just ran into a great post for integrating the Flex SDK with Eclipse. Adobe makes a free software version of the Flex SDK. When you look around for getting started with Flex Builder, just about everything points to Flex Builder, which isn’t available for GNU/Linux anymore. It is built on top of Eclipse, so I don’t know why adobe did this, but it is just one more reason to use free software tools that some vendor can’t jerk you in their direction. Springsource has some great projects working with the Flex SDK.
