I have written about building an Arduino-based soil monitoring system and how to predict time until next watering with linear regression. Yet, to see these results I had to shutdown the Arduino every morning, remove the SD card it was logging data to, copy that to my computer and run the analysis script. That should be wireless!
So I setup a bot for Telegram messenger that I can ask for the current measurements.
In the last post I wrote a follow-along to building an Arduino-based soil monitoring system. In this post I want to write about how I used linear regression to predict how much time is left until the plants are dry again.
Hibiskus wet (56.40%)
Walnuss wet (50.18%)
Dieffenb B 2 days (53.21%)
Dieffenb H 3 days (64.22%)
Yucca 7 days (45.06%)
Another thing I wanted to have since I was maybe 5 years old? PLANTS with MICROCHIPS! Probably the hardest part about keeping my green friends alive is making sure that they get enough water even when I am busy with other stuff, on vacation, etc etc. Now that there are cheap Arduinos to have it has gotten quite easy to realise this!
Vincent Bernat writes about the replacements he used to make his blog more privacy aware instead of relying on an abundance of external services. Whatever.
Cal Newport beschreib Silicon Valley’s tiefen Glauben daran, dass man die Menschheit mithilfe von Technologie verbessern kann. Dabei geht es nicht nur darum, Leiden aus der Welt zu schaffen, sondern auch darum, das Gute im Menschen zu vervielfachen. Wenn Menschen Bekanntschaften knüpfen und sich vernetzen um gute Dinge zu tun, dann könne es nur gut sein, wenn man dieses ins Extreme katapultiert und alle Menschen miteinander verbindet. Er bezieht sich dabei auf ein Memo eines Facebook-Ingenieurs, in welchem dieser seine Beobachtung beschreibt, das genau dies Facebooks DNA ist, das undiskrimierende Vernetzen aller Menschen überhaupt.
I read these lines as arguing that the natural state of human interaction is hopelessly irrational and ineffective. Facebook hopes to replace this “fragmented” state of human sociality with something better; something that spans borders and languages; something that offers many more connections; something that can leverage big data and smart AI to direct our relationships in an optimal manner.
This vision is classic High Modernism — merely shifted from city cores and farm fields to the digital realm. It should, therefore, scare the hell out of us.
If you went back in time 15 years, and showed James Scott a draft of Boz’s vision, Scott would almost certainly warn you that an attempt to reshape something as fundamental and messy as human sociality with a “better” technological solution would backfire in unexpected, dark, and painful ways.

It takes a lot of effort to explain how [an old game’s graphic art] is better than [a recent one’s]. However, it is easy to explain that the [recent game’s art] has a higher level of technology. To the average person, I’m sure it’s self-evident.
