Getting rid of Proxy limitations using Fiddler

If you work in a company that uses Proxy authentication (aka forces you to enter a password to access websites) and are a developer you know my pain: Some Most applications just don’t really like proxies. Visual Studio itself for example does not like proxy authentication at all and responses with a wide variety of error codes (407 for example).

You can get rid of all these errors through different workarounds, but these are a real PITA.

In addition the application you code itself needs Internet access, for example if you develop Office365 AddIns, you are very much screwed.

After a long research I finally found a solution using Fiddler.

Most developers already use Fiddler for debugging reasons so there isn’t even any software that needs to be installed.

Displaying Data from HomeMatic Actors on a WebInterface

This tutorial assumes that you already installed and configured FHEM and know how to use AngularJS.

 

As you might know I use my Raspberry PI to automate tasks at home. I already detect my SmartPhone, and my FitBit and also control my Webcam and Harmony remote using a raspberry and a web interface.

Now I also wanted to include actors from HomeMatic thermostats into my configuration and display it in a nice way.

Hardware used:

  • HomeMatic Wireless Configuration Adapter LAN (HM-CFG-LAN)
  • HomeMatic Thermostate HM-CC-RT-DN
  • Raspberry Pi V2.

Software used:

  • HTML/CSS
  • JavaScript
  • AngularJS
  • FHEM
  • PHP (optional)

Before we begin make sure you have already installed FHEM and the hardware for it. I will not discuss that here as there are a lot of good tutorials for that. A good (german) tutorial can be found in the FHEM Wiki. (If you got any english documentation, feel free to post it in the comments.) Continue reading

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

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 amazon.com, amazon.de 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.
