This tutorial is about how to build an online accessible thermometer using the Raspberry Pi 3 B-model.
We will start by buying the electronic components and finish with a chart showing the temperature data.
Walking through the tutorial requires basic knowledge in working with linux and advanced knowledge in building web applications. Whereas the web application part is optionally.
Using a mobile broadband connection and a thermo sensor our Raspberry Pi will measure the temperature and save it to a graphql server.
Using react and a graphql client library we will create a chart with the temperature data.
I form my opinions and judgments not based on newspapers and talks with people, but mostly from listening to podcasts and reading hacker news. An idea that showed up in my feed a lot recently, is establishing an Food and Drug Administration (FDA) for algorithms1 and technologies2.
Algorithms and technologies haven changed the very fabric of human interaction and communication. The economic landscape has shifted, the service sector took over the largest part of the pi and tech companies lead the top. Online platforms run by powerful algorithms and technologies have become the interchange for consumers and suppliers. Social networks turned into basic building block for socializing.
At AdNovum we are running GoCD for automating the continuous delivery (CD) of our software products. GoCD has become the de facto standard for running CD pipelines.
In this post I will give you a short introduction into GoCD using docker. We are going to setup a GoCD environment consisting of a server, an agent and deployable material. Further we are going to configure a deployment pipeline and build an node.js application.
I backpacked the north of India for three weeks. These are the impressions and memories I got from this amazing trip.
Garbage everywhere
This was the most shocking part when I arrived in India. There is trash everywhere and obviously no system nor institution that cares about collecting and recycling trash.
At the last Jazoon tech days I learned about the current state of DevOps and other related topics. During the talks “chaos engineering” and “observability” were mentioned many times. I didn’t know either and became curious what it was about.
First of all the solution to the problem I am tackling should not exist in the first place. If you have to revert a merge on a git branch, think about alternatives. If not other option is left, I’ll show you how you can undo a merge with git revert.
A friend of mine, who went working abroad last year, spent a few weeks in Switzerland. As he missed the mountains a lot, we decided to go hiking and camping in the south of Switzerland.
Equipped with two tents, 3 cookers and some clothes we took a 6 hour train ride from Central Switzerland to Bivio.
Over the last years I’ve visited many places in and around Central Switzerland. I’ve never been disappointed by the vast views and monumental mountains and valleys. Below you’ll find a collection of my favorite images of Central Switzerland.
