It’s because they at Microsoft hate web developers

That remark isn’t mine, it is from StackOverflow. 🙂

I had an issue that my Office365-App did not work correctly on the machine of ONE user. Sadly though that user was the Microsoft validation crew. I was unable to reproduce the error and did not even see any clue in the Server logs. Everything seemed to work fine.

Finally I managed to reproduce the error. It only happened under the following conditions:
1. Internet Explorer 11; IE – what else 🙂
2. Caching in IE has to be on “Automatic”
3. Developer Console MUST NOT be open
3.1. In fact: Even if you open it and close it afterwards, the error does not appear anymore
4. I had to retract/reinstall the app each time to check this behaviour which took about 10 minutes every time

I had issues with console on older IEs before, but at least angular uses some magic, so that issue is resolved. Nearly all questions in the web combining IE and console repeat the solution that you may not use “console.log()”. Continue reading

FlashAirDownloader 2

Development stopped! Please read this before downloading FAD
Keep your Version updated! Always click onto the “Check for Updates” in the Program after installation

The FlashAirDownloader 2 is out there (Because of my Laziness I will just call it FAD from now on)

A lot of people used the FlashAirDownloader which was meant as a personal tool and quick hack to access my Toshiba FlashAir Card. As more and more people asked me for features (and some for the code) I decided to make it open source so more folks can help improve the tool.

Sadly so: The code was a mess. As I told you: Just a quick hack. It would be to embarrassing to make this public 😀 So I decided to rewrite it from scratch: This time making it right regarding code quality and UI design. Nonetheless this program still uses Framework 4.0, cause I know there are Windows XP users out there who have no other possibilities to access the FlashAir.

Detecting Smartphone via Bluetooth on Linux (Raspberry Pi 2)

After detecting my phone using WiFi (which does only work under Marshmallow while the phone is loading or the display is enabled) and detecting the fitbit device I came back to my original task to detect my phone using Bluetooth.


While there are many documents out there that describe this on different Linux and even raspberry variants none of those really worked for me. The raspberry 2 (Debian Jessie) seem to be a bit different there.

First of all you need a Bluetooth USB dongle. I buyed the Logilink BT00015 (available at, or elsewhere). I would expect that others work, too. But as always: On Linux, drivers can be tricky and it’s always good to know working hardware.

Tracking fitbit presence under Linux (Raspberry Pi 2)

As I wrote before I track the presence of my smartphone using WiFi. Since Android Marshmellow this doesn’t work anymore, because when switching to idle mode, the WiFi is disconnected. The easiest way to get around this issue would be to use Bluetooth instead. And in fact: I already decided to go that way. But then my company gave me a nice present: A “Fitbit Charge HR”. While my company assured, that the HR is not for Human Resource and does not try to track if I am programming enough I decided to give this a try.

Being a nerd I am not that much into that “fitness”-area. But I like the device as a small watch and the vibration alarm is nice too. I will surely sync this with my Appointments lateron. Getting some information about how many steps it takes to get the beer out of the cellar or the chips out of the kitchen is a nice benefit. Not really useful. But at least nerdy 🙂

Control your Harmony Hub with a Raspberry Pi (Linux)

So my surveillance cam now only records when I am not at home. But what if I forget to turn off the TV? That should happen automaticly, too! But fear not: There is a solution – at least if you own a harmony hub. With the help of the “HarmonyHubControl” – tool (written in c++) this is done quite easily.
