Clone the Raspberry boot disk

Updated 2024-02-20 !

A very nice way to fix a backup is to make a copy, bootable, of the actual SD card You are using on the Raspberry Pi(RPi). This will be done even when the RPi is up and running !

This application can also be used to make a bootable SSD or USB drive !!

You clone from the command line so You don't need the standard GUI, Pixel, and the "SD card copier" function.

It is also possible to set up a a scheduled job, cronjob explained later, which for example makes a clone every night at 1 o'clock.

GRIB files and extracting data, Linux, Raspberry

Updated 2024-02-08

GRIB is a data format, used for meteorology, to store historical and forecast weather data. 

The use case for me was analyzing forecast data, from GRIB files, so an early warning could be rised before a high water level or coming storm appears. This could then be used at our weather site.

There are several applications, also ones that visualizes the data, but this post will handle how to extract data from files using command line.

Forecast without GRIB files ? Check this API for Europe.

Teltonika RUT 240 as source for Mesh Network or router

I have used the TP-link Deco M9 for quite a while and it have worked very well.

Since almost 2 years I have used mobile broadband as a source for the Mesh network, at home, via a Nokia Fastmile(NF) with no direct flaws.

Getting a very nice offer, half the monthly cost, for mobile Internet from our mobile phone operator it was time to test something new.

Since I probably will have to return the Nokia receiver quitting the old supplier I had to test the new provider with some other equipment. Running the Teltonika RUT 240(TR) in our yacht, in the summertime, it was available for testing.
