Observations and insights from boating world and ashore

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.

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.

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.
