pv-migrate is a CLI tool/kubectl plugin to easily migrate the contents of one Kubernetes PersistentVolumeClaim to another. On Kubernetes, if you need to rename a resource (like a Deployment) or to move it to a different namespace, you can simply create a copy of its manifest with the new namespace and/or name and apply it. However, it is not as simple with PersistentVolumeClaim resources: They are not only metadata, but they also store data in the underlying storage backend.

Finally, a working xsnow for Gnome, KDE, etc. Based on the original xsnow-1.42 created by Rick Jansen, after the xsnow-2019 conference in Antas (Spain) we now have available a xsnow that works on many desktop environments, even Raspian. By request of many beta-testers, a graphical front end has been created as well. For non-Unix users, there is https://sourceforge.net/projects/wsnow .

This software is used to extract operational data from the EPEVER Triron solar-PV controller, including its PV power output, battery voltage, load current, device temperatute, etc. Data collection is done in two halves: a client ("solatonclient") that talks to the controller via a serial port and RS-485 adapter, and a server ("solatonserver") that stores the information in files. The "solatonclient" sends information to the "solatonserver" over the network, and because it does not need to write to the file-system itself it can be run on a small computer such as a Raspberry Pi.

Command line script to flash SD card images of any kind. Note that for some devices (e.g. Raspberry Pi), at the end of the flashing process the tool tries to customize the SD card e.g. it configures a hostname or WiFi. And with a cloud-init enabled image you can do much more like adding users, SSH keys etc.

Solarity an enterprise working with PV systems is developing modbus drivers to get data from modbus devices (inverters, PV system loggers, energy meters, ...) and store its informations into csv files. Some files come from history beginnings and others have a higher level of abstraction where it becomes simple to add a new device with given documentation. You'll find basically SMA cluster controller, SMA inverter manager, SMA inverters, Schneider meter, Adtek meter, ABB inverters. ...
