In September (15th and 16th) we will be organising an IoT Hackathon together with Oracle. I preparation of that I will write several post here concerning IoT. This post gives you an Overview of Grove Pi sensors and some of the fun things that you can do with it. See also this two minute tech tip that is an intro to this post. The GrovePi+ Starterkit Connecting sensors to the Internet of Things (IOT) is really easy! No need for soldering or breadboards: plug in your Grove sensors and start programming directly. GrovePi+ is an easy-to-use and modular system for hardware hacking with the Raspberry Pi and the Internet of Things. Here is what the kit contains: The GrovePi+ Board 12 Grove sensors Grove cables for connecting the sensors to the GrovePi+ board. The following sensors and lights are in the kit: Grove – Sound Sensor Grove – Temperature and Humidity Grove – Light Sensors Grove – Relay Grove – Button Grove – Ultrasonic Ranger Grove – Rotary Angle Sensor Grove – ...

In September (15th and 16th) we will be organising an IoT Hackathon together with Oracle. I will write several post here concerning IoT, starting with this one where I tell you how to do the default setup of your Raspberry PI. See also this two minute tech tip that is an intro to this post. For configuring your raspberry Pi there are several options. I prefer to use a keyboard, monitor and mouse so I can actually see what I am doing. The Pi has several USB ports and also an HDMI port. So if you have a monitor, keyboard and a mouse available, you can plug those into your Raspberry Pi and you are all set. Connect to the power and the Pi will boot into an initial setup screen that allows you to select your preferred OS. That is of course only if you inserted an SD card in the Pi that contains the various available OS's. Select your preferred OS and click install so that the Operating System gets installed. After a short while, the installation is complete. Once the install h...

Sunday symposium took of at 8:30. Unfortunately i had to skip the first two session due to some work That had to be done first. The first session I really got to attend was Brian Fry's session on Oracles Developer Cloud Service. JDeveloper, Eclipse or Netbeans was the way you would work with Oracle Developer Cloud. Now there is a new feature (not publicly available) that is a browser based IDE. It is a full development environment. It is a very flexible, responsive and quick UI. it has an integrated out of the box GIT repository. It can be used for both JavaScript, and Java EE and java SE. Oracle uses the DevCS to build the DevCS with over 145 developers using 27 GIT repositories. So oracle now is drinking their own champagne, which sounds much better then eating their own dog food by the way.        The demo was nice and showed the power of the Javascript editor and the integrated support with GIT. also the Java editor looked very promising. We will have ...

During the closing keynote at the Oracle Fusion Middleware Forum XX in Budapest my former colleague Lucas Jellema and I delivered a live development demo. It was great fun to do. During this demo I developed an Oracle MAF frontend on top of Oracle SOA Suite 12c REST-JSON services. All in all it was a good session that was exactly delivered on-time with no errors. I think the demo gods where with us. In this post I describe some of the details regarding the Oracle MAF part of this demo. To be more specific, how the MAF application is able to work with the REST-JSON Services. In a later post I will go into the details of how to user interface was built. The details of the SOA suite 12c Backend are described by Lucas at the AMIS Technology blog in the following posts: Preparing  , Implementing part - 1   and Implementing part – 2 Before I start with the details I best describe the case first. We decided to create a tablet app that can be used by flight attendants...

Mobile apps usually have the possibility to toggle the springboard by using an icon that is displayed in the header of the app. The Oracle MAF reference app, Work Better, also tries to implement this behavior. The showing of the springboard works fine, however, hiding it does not really work as expected. In this post I show you how to implement a working custom toggle springboard functionality. Default Toggle Springboard Implementation First let's take a look at how the toggle springboard functionality works out of the box. In your application configuration file you need to set the "Show Springboard Toggle Button" to true in order to enable toggle functionality. All the rest is taken care of by the framework at runtime and these setting results in the default toggle springboard icons to show up on both iOS and Android. Note that this of course also works with a custom springboard. An obsolete way to implement Custom Springboard Toggle (you might want to skip ...

It has been a while since my previous post, and I have a very good reason for that. I have been busy, very busy. But now, after a long time of writing and rewriting I can finally announce that my book, Oracle Mobile Application Framework Developer Guide, is available for you to buy. Many thanks to my reviewers Chris Muir, Frank Nimphius and Joe Huang who guided and helped me all the way. If you are starting with Oracle MAF development, this book will give you a jump start. You will learn the concepts of MAF and MAF development and learn tips and tricks for MAF development. In Oracle Mobile Application Framework Developer Guide, I explain how to use this powerful framework to create multiplatform mobile apps based on a single code base. Detailed examples and ready-to-use code are provided throughout the book. A complete, step-by-step sample application highlights the robust functionality of Oracle Mobile Application Framework, including data visualization, UX pattern...
