Forgotten Skills: Build your own linux kernel

Firt we will talk about WHY. Many people have many opinions on that and I'd like to present you mine.

I work as System Specialist. During my work I often came to point that normal kernel from distribution doesn't work. Whole or part of server was unusable because one of these common reasons:

  • Virtualization support with combination of new HW

  • Missing driver for some Raid Controllers

  • Missing driver for network cards

  • Security hardening patches for specific systems


I don't remember which of the reason was the first when I must build my own kernel to be able use server or computer with all it's hardware. In few next years another big reason appear.

  • New kernel have fixed some performance issues


Now we can talk about how to do it.

ESP8266 + InfluxDB + OLED DIsplay and DHT22

Basicly just put together from Examples. Sending data tu InfluxDB was little bit tricky using HTTPClient and POST method for InfluxDB.
