I used a Kindle4 as status display some time ago. For some months this display was without power and I was to lazy to fix it. My solution in 2014 rooting and image generation is nowadays too complicated.

Ciko from my local hackerspace solved the problem in an easy way using the buildin webbrowser of the Kindle 4. No rooting required.

My kindle today:

Disable screensaver (source):

;debugOn (press enter)
~disableScreensaver (press enter)

For another project (the shackbureau) we needed to convert banking numbers from the old German system to the European system. At first we used the webpage of a German bank but after their relaunch the form was removed.

After some searching we found the data from the German federal bank as an XLS file. But XLS is a bad api to use from another site. The solution is the banking-api: https://banking.stupig.org/

Some usage examples:

1. Search for a banking number (old German system):

   https://banking.stupig.org/v1/bank?blz=10000000

2. Search for a banking number based on the new system:

   https://banking.stupig.org/v1/bank?bic=MARKDEF1100

3. Search for all banks in Berlin:

   https://banking.stupig.org/v1/bank?city=Berlin

4. Search for all banks with zipcode 10117:

   https://banking.stupig.org/v1/bank?zipcode=10117

5. Generate the iban based on old German account data:

   For example:

   curl --request POST --url https://banking.stupig.org/v1/iban/ --header 'Content-Type: application/json' --data '{"country": "DE", "blz": "64090100", "account_number": "1234567"}'

   returns

   {"country":"DE","blz":"64090100","account_number":"1234567","iban":"DE80640901000001234567"}
