I could tell you more about all the presentations I visited and how nice it was to listen to some great speakers, but I won't :)

Instead I would like to tell you more about the whole GOTO Amsterdam experience and the feeling I had after the conference.

Hippo CMS Favorite Folders Plugin

July 17th, 2013 by
(http://blog.trifork.com/2013/07/17/hippo-cms-favorite-folders-plugin/)

hippo_logoAfter doing a number of big projects with Hippo CMS, I came up with the idea of creating a plugin. I'm always looking for ways to optimize the user experience as I think user experience is one of the most important parts of a product. Hippo allows you to store your content in a folder structure. In my projects I've noticed that most users only use a few folders to work in. Sometimes this folder is located on a deeper level in the folder structure, which makes the user need to click even more before he reaches his content. My plugin allows the user to mark a folder as a favorite folder. A link will be created on the dashboard (the first screen after log-in). Using this link, the user can quickly navigate to that folder. The favorite folders will also be available in the link picker as a separate section. Continue reading to find out how it works!

(http://blog.trifork.com/2012/05/03/creating-a-mobile-version-of-your-website-with-spring-mobile-and-sitemesh/)

About a year ago I developed an Android app for my website, but as not everybody has an Android device I wanted to create a mobile version of my website. In the mobile version I want to present slightly different data to make it look more like the app. In this post I will show you how I have used Spring mobile to determine which version of the site the user wants to visit and how I used Sitemesh to select the correct decorator.

When I started with my Android application, I had the idea to create a home screen and an action bar just like one of the Android developers described in a blog item.

Migrating from Spring Integration 1.0.3 to 2.0.0.RC2

November 17th, 2010 by
(http://blog.trifork.com/2010/11/17/migrating-from-spring-integration-1-0-3-to-2-0-0-rc2/)

Spring Integration 2.0.0.RC2 is out and I really wanted to upgrade in my current project. Few of the reasons to upgrade were the dependency of Spring 3 and the support for JMX. Because SpringSource changed a few things in the 2.0.0 release, I want to share the steps I had to take and issues that I solve to migrate from Spring Integration 1.0.3 to the latest version 2.0.0.

(http://blog.trifork.com/2010/07/14/parsing-html-with-jericho/)

In one of our projects I had to parse and manipulate HTML. After searching for a nice HTML parser, I ended up using the open source library Jericho HTML Parser. Jericho provides you a lot of features including text extraction from HTML markup, rendering, formatting or compacting HTML. In this post I will show you a few of the features I have used.
