I’ve added 3 proposals for the ConFoo in Canada:
I would appreciate if you vote for my proposals:
Any developer who uses Cordova is aware of this: The source code of a Cordova/Phonegap App can be read in clear text. Just download the app archive (IPA or APK) and unzip it. Now everyone can read your source code. You can tweak or make it harder to read with uglify or minify but still it’s readable.
So there’s some neeed for companies and developers to encrypt your JavaScript code in an hybrid App, too. tkyaji published a plugin on GitHub, which makes this possible: the Cordova Encrypt – a Plugin Cordova und PhoneGap encryption.
The plugin works for iOS and Android. Just add it to your project with cordova plugin add cordova-plugin-crypt-file. Now a cordova build encrypts all .html.htm.js.css files. Therefore keys are generated in the native containers so that the files aren’t readable anymore. The decrypions is done automatically on app start.
It’s a pain for testers and developers. Running an application with different browsers. Resize the browser window and verify that the web page is working on different screen size. Due to “Responsive Design” there are high efforts on this kind of stuff.
Sure it’s possible to calculate the delta between images to ensure that the layout does not differ between the last checks. But especially when you build up a new application or start a new design this approach doesn’t really work out. Here comes the Galen Framework to the rescue: Describe like in TDD you’re requirements in a DSL and let the framework verify it for you. The Galen DSL uses relations between elements to describe your checks. For test execution the Selenium automation stack is used. So you can even utilize Saucelabs. And the Galen Framework can be used in Java– und JavaScript projects. Additionally Galen delivers impressive reports for analyzing the failures:

The problem is everywhere for a typical multi-tier architecture. The UI calculation is done at server-side and the browser just displays the data. That was the typical architecture for several years. Every interaction with the user needs the server backend. Especially with lower bandwidth this is a big issue and the server needs to know the client state, which cases additional memory and processing capacity. And on top the user interface feels sluggish. Increasing the server capacity doesn’t really help in the most cases…
With AngularJS there is currently a very solid web framework availably which helps the describe the user interface with HTML/CSS and implement – even for bigger applications – the business logic in JavaScript. In such applications the client itself needs only to remember the state and the backend can leverage RESTful web service, like JAX-RS within a JEE-area.
By using the approach you get a solid fundament to delivery real business applications for mobile devices. These hybrid applications can run with the same implementation on several platforms and also leverage some platform features, like push notification or background network fetch.
Such a sample application which uses a RESTful backend and WebSockets was made by me for demonstration purposes. You can download it on GitHub. The sample shows that HTML5-based hybrid apps with a native container like Apache Cordova can delivery high quality apps that feel like native apps in most cases.
DSL’s are the new buzzword together with Cloud, not only since Groovy or similiar tools. With Xtext you get a really easy to use tool for creating an Eclipse-based editor and code generator. Xtext is a powerfull toolset, which eases the creation of your own DSL. To find out more about Xtext please check my presentation or take a look at the example for building Xtext projects with Maven and Tycho on GitHub.

After the latest Update of Google Chrome the recent closed tabs are gone and the new homepage is used. I don’t like the new one and found I trick restore the old homepage again. So I’ll share it here. I’ve taken the steps from the Chrome product forum (http://productforums.google.com/forum/#!topic/chrome/6oFu2gXMGzk):
I’ve created a new Version of my Roundcube App for OwnCloud, which adds a Autologin feature to the app.
Screenshot of Roundcube App for OwnCloud
So if you’re using the same user in owncloud and roundcube, you don’t need to save your credentials in roundcube. They will be automatically saved to the app.
The error handling is now much better and helps the user with configuration errors
The code is now more cleaner and the log doesn’t show PHP errors anymore, instead the error handling should help to figure out what’s the problem.
The following issues were fixed:
This should be the last version before the next major release 1.2 If anyone wants to have a new feature added for 1.2, feel free to to open up an issue, here. For release 1.2 I will add multiple account support.
If you experience the problem that your mac freeze after one or two hours of usage, you shouldn’t blame Apple, if you’re using a SSD: I’ve found this entry. The error came up from a firmware error in the Crucial SSD. So I went to the Crucial homepage, burned the ISO-File onto a CD and boot from it (on mac you need to press the ‘alt’-key to get the boot menu).
And voila, after a reboot all was working again…
I’ve recently updated my Roundcube App for OwnCloud, which is now compatible with OwnCloud Version 5:

Good software is important. Everybody should now that…
But how to do that? by sharing the experience and maintain a community. So one very good way is to sign the Software Craftsmanship Manifesto and participate in the community. You can join the germany community share your knowledge and participate in the network
And because christmas will be soon, you can order a nice calendar.
