Installing Ubuntu 24.04 or 24.10 on an old MacBook Air(2011)
A while ago i tested Mac OS Sonoma(14.5), on the mentioned Mac, but I had to admit that Sonoma was a little to much for the 13 year old companion.
I really like the Mac and everything works, after a battery change, so it ended up with installing Ubuntu 24.04.1 LTS or if you want the latest scroll down and get Ubuntu 24.10.

Node-Red quick install
Node-Red(NR) is Flow-based programming for the Internet of Things
This post isn't made as a complete install guide, there are several, just some links to the best information I have found.
The best thing is that even if you don't are a skilled programmer, but like logic flows, you can make really advanced things. It's pre-installed on some Raspberry Pi(RPi) distributions.
Running Node-Red with multiple instances ?

Raspberry 4,5 USB SSD boot in 60 seconds !
If you have a RPi 4, 5 and a USB SSD or other USB drive, that works as a boot media, just use the RPi imager which can write the image direct to the USB storage.

Raymarine E120 & E80 backlight failure
It's from 2006 so I'm not surprised that things happen. You may wonder why we keep it instead of buying a new one but the thing is that we have 2 installed together with a well functioning radar so buying new stuff will be a hefty price tag.
After some Googling I found out that the backlight is produced by a CCFL, a type of neon light, and can give up after some years.

IVT, Bosch heat pump easy integration, Home Assistant
In search of the optimal solution on how to interface our IVT Heat pump, first try here, I stumbled over a nice integration for Home Assistant(HA). A first quick setup is shown at the right.

Home Assistant core install, Raspberry Pi and Python 3.12
It works very well and here are the install instructions.
On the other hand if you want to add HA to a RPi which you already have up and running, without Docker, you need to install something which is called "Home Assistant Core".
Please check the "Remarks" below before you start.

Clone the Raspberry boot disk
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.

Teltonika RUT 240 as source for Mesh Network or router
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.
