Strangely, it is still fairly complicated to transfer data from the smartphone to the computer. There are cloud solutions and bluetooth but thats still complicated or slow. But my friend and ex-colleague and me just release a first version of NetCatdroid. NetCatdroid is a netcat client for Android which allows you to transfer multiple files to your computer via netcat. Especially Linux and Mac user will love it, because nc is preinstalled on most systems.

In early 2016, we created a indoor positioning prototype for tracking stuff in a retail market. The Devices, that we used for it, were - of course - Raspberry Pis. But we needed about 100 of them. Here you can see, how we assembled them recorded in time lapse. 

Round 1: Called the Raspberry Pi Challenge: Were each colleague was assembling a Raspberry Pi as fast as possible. We took the time and tried to beat each other.

Okay that's new to us android developers: You can no longer get the hardware MAC address of a android device. WifiInfo.getMacAddress() and BluetoothAdapter.getAddress() methods will return 02:00:00:00:00:00. This restriction was introduced in Android 6.0.

I wanted to know if this is true. So I tested this on my OnePlus One (Android 6.0.1 Cyanogen).

Raspberry PI 3 Preisvergleich für den Kauf in Deutschland

Geburtstag und noch viel wichtiger: vor kurzem ist der Verkauf des Raspberry Pi 3 gestartet. Laut offizieller Website der Raspberry Pi Foundation kostet der Raspberry Pi 3 nur 35$ (knapp 32 Euro). Wie wir sehen werden stimmt das jedoch nicht ganz, zumindest in Deutschland.

Gut zu wissen: Da Form und Größe absolut identisch zum Raspberry Pi 2 Model B sind, können alle Gehäuse und die meisten anderen Zubehörteile bei der neuen Pi Version verwendet werden. Außerdem ist WLAN und Bluetooth 4.0 schon mit an Board.

In Deutschland kann man den Raspberry Pi 3 bei vier Partnern von element14 kaufenEXP GmbH (Germany), Heinz Büchner Elektronik (Germany), Pollin (Germany) und Watterott electronic GmbH (Germany). Wir haben die Preise verglichen (Stand 29.02.2016).

App: Brussels comic strip walk android app

One of the coolest thing to do in Brussels is of course the "Brussels comic strip walk". On various buildings in the city artists have painted gigantic Comics like Tintin and Lucky Luke. It belongs to one of the main tourist attractions in Brussels. Sometimes it is really hard to find the comic strips because the are also inside of buildings. When I lived in Brussels I the the whole tour and I made photos of every single comic strip.
