by Hendrik Will. 0 Comments

After installing Linux Mint 13 using MATE I wondered about the new path bar in the File Explorer’s. Before the default was a Textual Location Toolbar. It came in quite handy if you wanted to copy and paste a folder or quickly access a Samba share on your local network.

Eclipse Java EE jQuery Validation Error Workaround

by Hendrik Will. 1 Comment

During my recent Java EE project I came across an annoying bug which always showed an Error Symbol on my root project folder. At first I thought it was a Java error but then I saw it was caused by the minified version of jQuery (jquery-1.7.2.min.js) in my case. This is an Eclipse bug already reported in summer 2011. I guess this can also happen with other minified JavaScript files.

Measure elapsed time in Nanoseconds with Java

For my recent experimental gaming project I wanted to measure the overall elapsed time since the beginning of a game.
In my main class I added a startup variable of type long which contains the current time in nanoseconds. At the end of a game call the function stopWatch(startup); to get the elapsed time in seconds.

Flickering Sencha Touch Animations on Android

by Hendrik Will. 3 Comments

After deploying my project on Android Devices I found out about some annoying bug in Sencha Touch. It causes flickering on Android when using Animations like cardSwitchAnimation: ‘slide.’ All available solutions didn’t seem to fix this issue on my setup completely. I was using a tabBar at the bottom of my application and the icons of it didn’t get rendered when the app loaded for the first time.

A couple days ago I began to develop my first mobile web app with the Sencha Touch Framework which is a HTML5 Mobile Web App Framework.

Hibernate Dependencies for a Maven Web App

by Hendrik Will. 0 Comments

If you’re using Maven to build a Web App with the latest version of Hibernate you only need to add the hibernate-core dependency to your pom.xml (Project Object Model).  The Hibernate project added their own pom.xml which will download all other library dependencies from the Maven repository for you automatically.

I saw that many blogs still refer that you have to add many dependencies to use Hibernate which confused me a lot. Also JBoss recently started to sync their repository with the Maven repository. So there is no need to add another JBoss repository to your pom.xml.

“TYPO3 Templates” book review

by Hendrik Will. 2 Comments

Packt Publishing asked me to review their latest book about TYPO3 Templates by Jeremy Greenawalt.

This book covers everything you should know about TYPO3 Template Engine TemplaVoila. You’ll learn everything from install of the extension to mapping a template from scratch. This method more easy  than the classic marker method or the makeautotemplate extension.

The book also has a whole chapter about different kinds of menus TYPO3 brings with it and shows how to use them with TemplaVoila. Another interesting chapter is about customization of the backend for backend users and groups.

Last but not least they even cover BusyNoggin’s TemplaVoila Framework in a whole chapter. This is quite interesting and you should definitely read it.

In my opinion this book gives a good overview about TemplaVoila template building and even gives some outlook to the Framework. I think this book is good for beginners and intermediate users who would like to learn using from scratch or learn some more advanced techniques. Designers should be familiar with HTML/CSS. Experts may not find anything new.

Table of contents

Sample Chapter: Chapter No.4 ”Creating Flexible Menus”

Here you can buy the book!

Is Jolicloud 1.1 really the web of tomorrow?

by Hendrik Will. 1 Comment

I just stumbled upon the Jolicloud 1.1 operating system which has been developed especially for Netbooks. It is based on the Ubuntu Netbook Remix Linux distribution and shows lots of HTML5 capabilities. There is a Windows installer but you can also install it as your primary operating system. To gain a better impression of Jolicloud I installed it as virtual instance  with Oracle’s VirtualBox. Of course you could also install it on your USB drive.
