# Brennenstuhl Premium-Web-Line V3 is a socket strip with an embedded web server. 
# It can be switched via a web interface or using http get requests. The latter is a bit under-documented, 
# so here's what i found out:
# The built-in server accepts only authenticated http get requests (using digest auth).
# each command has its own url, like so: http://{IP-OF-THE-SOCKETSTRIP}/cgi/{commandname}?params
# full list can be found in a PDF called "Premium-Web-Line V3 CGI specification.pdf" which is included in the download package of the official software:
# download link -> https://www.brennenstuhl.com/index.php?module=explorer&index[explorer][action]=download&index[explorer][file]=firmware/premium-web-line-v3-software-3_3_6.zip

# here's an example on how to toggle one of the two relais (nr. 0)
# modified a general digest auth example from stackoverflow: https://stackoverflow.com/questions/23254013/http-digest-basic-auth-with-python-requests-module

Re-encode all .txt files in a directory from windows-1252 to utf-8 in place

• using find and iconf commands on osx
• replaces original files!
• two-step process:
  • first store all paths to text files in a separate file
  • then do conversion based on each file path
  • why? find -exec with iconv was too hard to figure out on macOS

Run processing.org 3.x exported sketch from commandline

example under OSX:

if you have a sketch called Test.pde

• navigate to application.macosx/Test.app/Contents/Java
• then call the following line java -cp "*" Test
-cp "*" makes all the jars in the directory available to java

# deckset_collect.py
# by jens wunderling
# this script collects all assets used in a deckset presentation into one folder and creates an updated .md file
# useful if you wildly use image files all over your local file system
# and for archiving (if online sources go offline)
# i'd like this to be a feature of the main app though :D
