the story behind pi3g
Back in 2012 the story of Maximilian and the Raspberry Pi started. He was excited when he got his first Pi and also saw the great potential for further development in it.
Then PiCockpit was born to make using and managing the Pi easier and more accessible for everyone.
Maximilian has always been interested in computers and believed that they are a lever to improve everything in the world - for example in medicine.
Over the years, Maximilian's work has grown and new fields of expertise have emerged...
working at pi3g
In our blog you can expect blog posts about technology and business topics, of course about the Raspberry Pi, but also a wide variety of topics related to Industrie 4.0, IoT, and machine learning - for example about the popular MQTT protocol, Python and Linux embedded development, and much more. Blog entries are not scheduled and not in particular order - the topics are an eclectic mix of what comes up in real life of a company engaged in machine learning & Raspberry Pi embedded adventures.
We are happy to write about special topics that are not so well-documented elsewhere.
If you have any suggestions, we are happy to discuss current topics with you and are always ready to brainstorm workable solutions with you.
The scope of ecr within crystal: or how do I pass in variables and Objects into ECR templates?
As a beginner in the Crystal language I still struggle to get my head around some of the concepts in it, and develop a feel for coding in Crystal.When I come across difficult problems, which I solve or start to understand, I blog about them, so others can benefit – as lack of documentation is…

There are different options, see here https://www.envoyproxy.io/docs/envoy/latest/api-v2/api/v2/route/route.proto#route-redirectaction This envoy.yaml routes /taxgod and /taxgod/ (the second could probably be omitted because the first one should also match it, I think) to a new port and a different protocol. /picockpit is simply redirected to / and then finally…

It is possible to rewrite URLs with Envoy for the backend. Please note that the HTML output needs to have the proper routes! (That is why I am not going to investigate further in this direction). REF: https://www.envoyproxy.io/docs/envoy/latest/api-v2/api/v2/route/route.proto#route-route Also note that the string is going to be rendered literally for direct_response –> body –> inline_string,…
read moreenvoy as http 2 front proxy – enabling http 2 for envoy (aka h2)
Out of the box envoy is not configured to set up connections with clients connecting to it with the new HTTP/2. HTTP/2 is optimized for the modern web, with binary headers, etc. – higher speed. Since envoy is capable of speaking HTTP/2 to clients, it is a no-brainer to set it up. And the setup…
