Updated 2024-03-01 ! OpenPlotter(OP), a Boat Navigation application, is really a nice and simple installation of OpenPlotter (OP) OpenCPN (OC) SignalK (SK)  and other supporting applications for Your boat. An overall information about the OP package is found here . Install guide for the new stable OP, version 4, is found here .

Updated 2025-01-23 ! With my project to keep a MacBook Air 2011(MBA) alive , Ubuntu installed, i searched for a solution where my iCloud drive(iCD) was  continuous synced with my MBA. This must work both ways so even a file change made on MBA should be replicated to iCD. rclone now, 2025-01, works with iCloud !! Setup below !! Before "rclone" was working with iCloud I solved my sync between iCD and MBA with Syncthing (ST). Check below. ST doesn't sync with iCloud so the work around here was to use my MacMini, Mac OS, as the "Middle man". It's always on and synced with iCD.

Updated 2023-10-17 ! To make a headless, without monitor, keyboard and mouse, install of Raspberry Pi OS on a Raspberry Pi(RPi) with built in WiFi and no LAN cable connection, please follow the instructions below. For example the RPi Zero and Raspberry Pi 3 Model A+ don't have any LAN cable port so the setup is quite usable. To make an active WiFi connection at first boot You have to use the "Advanced options" in Raspberry Pi Imager or create, old way, a configuration file called " wpa_supplicant.conf ".

Instead of buying  a new Z-Way adapter I thought it would be a nice project to reuse the almost 10 year old RaZberry 2(RZ) adapter together with a Raspberry Pi 2(RPi).  After some Googling I found  Z-Wave JS UI (ZUI) which is both the server part and an UI. The described installation could be used for almost "any" Z-way interface, impressing list ! , and for "any" Linux distribution.

Updated 2023-10-12 ! In a former post I shared some thoughts about how to start using NetworkManager (NM), on a Raspberry, and here I will continue with additional examples that can help with network setup. NMTUI is NetworkManager text UI which can handle the most common tasks in a easy way. An access point or hotspot will be configured. " sudo nmcli connection edit xxxx " is a command that guides you throw a change of parameters.

 Updated 2026-07-09 ! I have done several posts Blogging about how to keep an old MacBook Air(MBA), mid 2011(A1369), with SSD disk "alive". I have used the fantastic software package OpenCore Legacy patcher to upgrade the Mac to the latest Mac OS.  A while ago i tested Mac OS  Sequoia (15.3), on the mentioned Mac, but I had to admit that it was to much for the 14 year old companion. I really like the Mac and everything works, after a battery change , so it ended up with installing   Ubuntu latest LTS (UOS) ! (Above link is now UOS 26 LTS which I have not tested) Ubuntu on  Mac Mini (2018) and MacBookAir (2010)  ?

 Updated 2026-07-05 !  After testing Home Assistant (HA) for a while, I’ve realised it could improve my home automation, despite that I'm mainly using Apple HomeKit. When I tested HA with Node-RED and some other "Add-ons", on a Raspberry Pi 3 (RPi), I found that its resources wasn’t enough. The following setup could be any computer but I recently bought an Apple Mac Mini M4, replacing my 2018 (M18) model, so the M18 was really a great candidate for my HA setup. I have converted to HA running on Proxmox !   😀

Updated 2025-10-15 for Trixie ! The purpose of a watchdog timer(WD) is very well described here but a more practical answer is; If your Raspberry Pi(RPi) "freezes", or hangs, it will automagically reboot within a very short time. This is made with a combination of hardware and software which is all ready available, on the RPi, and just have to be enabled. After some hours Googling and testing these are my findings !

Updated 2025-10-02 ! I like the Raspberry Pi(RPi), with Raspberry Pi OS Lite (no Desktop is included), headless operation, and then adding the software You need. Until now I haven't had a use case where I needed a Desktop but now was time.  Why don't use the Raspberry Pi OS with Desktop ?? In that package there is a lot of software I don't need and I really want to optimize the RPi. I think that the less software You install the happier RPi will be... 😉
