Looking for ways to improve Podcastpedia.org‘ mobile user-friendliness, I have discovered Google’s PageSpeed Insights . After analyzing the home page, a podcast’s page (The Naked Scientists Podcast – Stripping Down Science), an episode page and scoring an average of 70 out of 100 (even worse on mobile) two points needed urgent fixing:

1. Enabling compression

Compressing resources with gzip or deflate will reduce the number of bytes sent over the network at the expense of slightly increased CPU utilization. Smaller files also mean less bandwidth used and faster transfer time. At Google’s recommendation I have enabled file compression on the Apache web server, for which you have to use the mod_deflate module.

1.1 Enable mod_deflate on GoDaddy

To enable mod_deflate on a GoDaddy Virtual Private Server account, you have to use Easy Apache and the same procedure as in Troubleshooting WordPress installation on GoDaddy VPS. You need to check the Deflate option at step number 5. Exhaustive Options List and recompile the Apache Server.

easy_apache_deflate

To verify the module mod_deflate is active run the following command on CentOS

httpd -M | grep deflate_module

I recently switched to Eclipse Kepler, being very dissapointed in the Juno Version – sometimes it took a couple of seconds just to switch between open tabs, and that on a 16 GB RAM machine with a 8-core processor… Anyway, I will shortly present here how I have configured Eclipse for the further development of Podcastpedia.org:

This post is about automatically generating sitemaps. I chose this topic, because it is fresh in my mind as I have recently started using sitemaps for Podcastpedia.org After some research I came to the conclusion this would be a good thing – at the time of the posting Google had 3171 URLs indexed for the website (it has been live for 3 months now), whereby after generating sitemaps there were 87,818 URLs submitted. I am curios how many will get indexed after that…

So because I didn’t want to introduce over 80k URLs manually, I had to come up with an automated solution for that. Because Podcastpedia.org was developed with Java, it came easy to me to select sitemapgen4j

Maven depedency

Check out the latest version here:

Podcastpedia.org makes use of Apache Tiles for its layout. This approach was taken because the website pages share a similar structure. Please read first the Getting started guide and Tiles concepts to have a better understanding of what follows. This post will present how Tiles is integrated with Spring MVC for Podcastpedia.org

Note: Spring is the basic technology used for developing Podcastpedia.org

Necessary artifacts

First of all Tiles jars are required in the classpath. They can be directly downloadded from the official website, but Tiles has also been published to the public Maven repository.

You can use one dependency to download all Tiles supported technologies with the following dependency declaration:

<dependency>
    <groupId>org.apache.tiles</groupId>
    <artifactId>tiles-extras</artifactId>
    <version>2.2.2</version>
</dependency>
