Linux for a test? Launch it directly from a flash drive in 5 minutes

The ideal starting point is the safest way to familiarize yourself with a desktop Linux system directly on your PC from a flash disk. We have prepared a slightly modified "live persistent" distribution of Kubuntu 25.04 for you to download. This means that it saves the modified content, and you can use this operating system from the flash disk repeatedly. You will immediately see how compatible the distribution is with your computer, and you can confidently try out a web browser, multimedia player, video conferencing, or install an application from the Discover or Snap Store. The LibreOffice office suite is also included, allowing you to open any documents or spreadsheets. Or simply explore this free environment.

"Save anything you need, and then you can come back to it later

a portable, versatile system that you can plug into any computer and run without affecting the primary OS installation"

If you encounter any occasional slowdowns, it's most likely due to the flash disk. Generally, Linux distributions are faster on the same computer compared to MS Windows and require fewer resources, so they work smoothly even on older computers. However, for full-fledged everyday use, they should also be installed on the hard disk like any other operating system. You can perform a permanent installation on the hard disk directly from the mentioned live distribution if you like the system. It's free, no registration, no ads, no commerce.

Software

Kubuntu 25.04 LTS Live Persistent

Kubuntu is based on the Ubuntu distribution and, although it certainly does not belong to the most widely used Linux distributions, in our opinion, it is a very good choice for first-time users and learners.

1) Download the live persistence distribution where we have preinstalled a few applications like VLC, GIMP, etc.

2) Download the Etcher program. It is a utility used to correctly write the downloaded file to the flash disk:

You can also use the portable version, which does not require installation and can be run directly. Insert the prepared flash disk, launch Etcher, select the downloaded Kubuntu .img image. Make sure that Etcher shows your Flash disk (disconnect other flash disks for safety), and once you are sure, click Flash!

After finishing, insert the flash disk into the computer where you want to try using the Linux operating system and restart the computer. Once the computer logo appears, press the key to select the boot device. It is usually the F12 key (Lenovo, Toshiba, Dell), ESC key (HP, Sony), or F8 key (Asus). If none of them work, try finding the manufacturer in the table on this link. From the offered list, select USB or USB FLASH device to boot the system.

BMW i3 in Smart HomeRating: 100%

In this article, we will show how to get information about the BMW i3 into a tablet using OpenHAB. Of course, you can use the MyBMW app, but with the API, we have the opportunity to customize the interface, display simple dashboard with all information on a single page. It is also possible to send supported commands via the API, such as opening, closing, starting the air conditioning/heater, etc., and, most importantly, to integrate these actions with a smart home system.

Tailscale - remote access without public IPRating: 90%

The Tailscale service solves access between individual devices if you don't have a public IP address. It's free for one user with support for up to 100 devices. We'll show you how to install Tailscale on a Raspberry Pi that you'll have at home and on a client (Android, iPhone) from which you'll want to access the home Raspberry Pi. Our example will be remote access to OpenHAB running on a Raspberry Pi. However, the same setup applies to many other applications - home NAS, PiHole, Home Assistant, Domoticz, NextCloud, and others.

Shelly vs OpenHABRating: 90%

The Shelly brand is known for its products that primarily communicate over WiFi, including smart plugs, relay switches, blinds control relays, and many other devices. One of the advantages for deployment is the ability to both read and control these devices using the universal MQTT protocol. Across existing add-ons for both OpenHAB and Home Assistant, we will demonstrate how to use Shelly devices without installing any additional extensions.
