IoT Hackathon Part I : Setting up your Raspberry Pi

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 has finished you need to confirm by clicking OK, the system reboots, and you will automatically enter the Raspberry Pi Configuration Tool (raspi-config)

One of the things you should do is to enable SSH so you can actually enter your raspi from a different computer. I'm not sure if it is enabled by default, but just go into the raspi-config, select Advanced Options (8) and go into A4 SSH to enable it.
You can also change the default password (which is raspberry) and the default name of the device (which is raspberrypi).

Reboot one more time to activate the changes, and you are ready to start programming.

If you are happy with commandline interface, you can go wild on that one, but if you prefer to work in a GUI, you will be able to change that by using raspi-config. Open raspi-config by typing:

 sudo raspi-config

The config menu opens, and you can change the boot option by selecting option(3). So enter this option, change the setting and reboot the Raspberry Pi. It will enter GUI mode and you will have a nice Graphical UI that you can work with.

That will be all for now. I will continue posting about our IoT Hackathon. More info can be found here.

ADF 11g popup and panelwindow: Open wikipedia in a modal popup.

This post was more or less inspired by the noteWindow example on Oracles tag demo site. When hovering the highlighted text in this example the user gets extra information about the subject. I wanted to give the end user the opportunity to get even more information, for instance by invoking a wikipedia page about the subject. The catch here is that I wanted this information to be shown in a modal popup, and one that is not prohibited by popup blockers. Luckily ADF 11g provides javascript popups that can also be made modal, so the user has to close the popup before returning to the application. This post describes how I used an in a to open the correct wikipedia in a modal popup. Step 1: Create the plain text that invokes the noteWindow. This is taken directly from the mentioned Oracle example. <p style="margin-left:30px;width:500px;margin-right:30px;line-height:16px"> Vultures are scavenging birds, feeding mostly on the carcasses of dead animals...

ADF 12.1.3 : Implementing Default Table Filter Values

In one of my projects I ran into a requirement where the end user needs to be presented with default values in the table filters. This sounds like it is a common requirement, which is easy to implement. However it proved to be not so common, as it is not in the documentation nor are there any Blogpost to be found that talk about this feature. In this blogpost I describe how to implement this. The Use Case Explained Users of the application would typically enter today's date in a table filter in order to get all data that is valid for today. They do this each and every time. In order to facilitate them I want to have the table filter pre-filled with today's date (at the moment of writing July 31st 2015). So whenever the page is displayed, it should display 'today' in the table filter and execute the query accordingly. The problem is to get the value in the filter without the user typing it. Lets first take a look at how the ADF Search and Filters are implemented by...

ADF 11g : Printing Directly From Your Application

Last week I was asked this question : "Can we print directly from within our ADF Application, without invoking the printer dialog ?" I wasn't sure but after some investigation the answer was clear. Yes you can ! Here is how... I decided to create a print start up form where I can select printers and print the document. Most of the functionality needed is provided by the Java Print Service API. Selecting available printers I start with a way to show all printers available to the session. For that I simply use the PrinterServiceLookup. PrintService[] printers = PrintServiceLookup.lookupPrintServices(null, null); The result I can now use to create an Array of SelectItems in order to make the list available in the application. 1: public SelectItem[] getAllPrinters() { 2: if (allPrinters == null) { 3: PrintService[] printers = 4: PrintServiceLookup.lookupPrintServices(null, null); 5: allPrinters = new SelectItem[printers.length]; 6: for (int i = 0; i ...
