Basic work with Qt 6: KaOS 2021.01 published

With the switch to version 6 of the application framework Qt, which is used for the cross-platform development of user interfaces, the KaOS developers are preparing their distribution for a change from the plasma desktop to the Qt 6 basis. A number of applications in KaOS are already based on Qt 6. For the first time on board are Stacer, a graphical tool for managing systemd services and IsoWriter as KaOS’s own start media producer.

The independent Linux distribution KaOS provides updates on an ongoing basis, usually according to the rolling release model. New packages are imported with the Pacman package manager known from Arch Linux. However, the developers publish snapshots in the form of ISO files at regular intervals to make the installation easier for newcomers.

Qt 6 and new applications On the KaOS website the project gives an overview of the innovations. The current KaOS snapshot contains the first applications that are based on the Qt 6 framework, for example the music player Strawberry forked by Clementine and the Qsynth synthesizer. In addition, the components of the PyQt stack, such as Sip 6, PyQt Builder and PyQt 6.0.0, are based on the new framework. The packages of the plasma desktop Plasma 5. 20. 5, Frameworks 5. 78. 0 and the KDE Application Suite 5. 15. 2 are all based on Qt 5. 15. 2. KaOS 2021. 01 comes with Linux kernel 5. 10. 6.

The new KaOS 2021. 01 has some new applications in its luggage, such as the matrix client NeoChat or the Barrier program, with which several systems in the network can be connected with a mouse and control keyboard. KaOS uses systemd-boot as a boot loader for UEFI installations. Stacer replaces systemd-kcm as a tool for the graphical administration of systemd services and also functions as a system monitor.

Stacer serves as a system monitor and can systemd – Manage services and startup programs.

New tricks when installing the system KaOS sets on the distribution-agnostic installer Calamares, whose partition module has mastered “Split Encryption” since version 3.2. 35. The feature allows users to encrypt the hard drive when installing KaOS, / boot but leave it unencrypted. The user module now offers a more detailed management of the user groups.

The in-house startup media producer IsoWriter can delete the partition data of a USB stick that has served its purpose as an installation medium. This should simplify the subsequent reformatting so that users can use the stick again for regular data transfer. If required, IsoWriter can check the integrity of the start medium by comparing the MD5 hashes of the ISO file and the written image. This verification can also be carried out via the context menu of the Dolphin file manager.

Clear objective According to its own presentation on the project page, the KaOS project does not pursue the goal of providing the widest possible range of software and desktop environments. Instead, the developers are “focusing on a DE (KDE Plasma), a toolkit (Qt), an architecture (x 86 _ 64) “.

The developers advise against this in the installation instructions to use the startup media creators Rufus and UNetbootin. In a short experiment, the ISO image could be written to a USB stick with Linux using the dd command or the Etcher tool. An installation of KaOS on systems with RAID is currently not possible. Those interested can find further innovations in the release announcement. KaOS 2021. 01 is available as a direct download on the project page.

Paramount Plus, ViacomCBS’s new rebranded version of CBS All Access, launches on March 4th

ViacomCBS is set to relaunch its CBS All Access service as Paramount Plus on March 4th, with a special event to introduce the new streamer on February 24th, the company announced today.

The service will also launch in Latin America on March 4th, followed by the Nordics on March 25th and Australia in mid-2021. The version of CBS All Access that is currently available in Canada will rebrand to Paramount Plus on March 4th, with an expanded offering being made available to subscribers later in the year. To better introduce Paramount Plus, and give a more comprehensive look at ViacomCBS’s overall streaming portfolio (that includes Pluto TV and Showtime’s OTT service), the company will host a two-hour event on February 24th following the company’s earnings call.

ViacomCBS CEO Bob Bakish previously announced in September that CBS All Access would rebrand to Paramount Plus, and noted in a later interview that executives decided upon the name because Paramount had more brand recognition than CBS. Paramount certainly has more name recognition internationally where the label has been used on more products (Paramount Plus already existed in some capacity in parts of Europe), but Paramount in 2021 isn’t exactly Disney or Warner Bros. As The Verge previously noted:

It would be one thing if the Paramount name was going to drive hordes of people to sign up because Paramount is synonymous with big franchises in 2020. Franchises like Marvel, Pixar, and Lucasfilm are synonymous with Disney (alongside Disney live-action and animated films), so Disney Plus works. How many people are walking around going, “Oh right, the studio I closely associate with Mission Impossible, Transformers, and Sonic the Hedgehog movies.”

Still, ViacomCBS is going to try very hard to sell Paramount Plus as a must-have service for people. Or, more accurately, ViacomCBS is hopeful that Paramount Plus will take some attention away from Disney Plus, Netflix, Peacock, HBO Max, Apple TV Plus, Hulu, Amazon Prime Video, and wherever else people are streaming.

To do so, ViacomCBS is introducing a number of new originals for Paramount Plus. Those include The Offer, a 10-episode scripted miniseries about the making of Francis Ford Coppola’s The Godfather, a new iteration of MTV’s Behind The Music, and a revival of The Game. Plus, more than 30,000 additional episodes and movies from ViacomCBS’s various content houses (BET, Nickelodeon, MTV, Comedy Central) are headed to the streaming service. This could only be done because of the merger between CBS and Viacom in 2019.

Raspberry Pi 4-Track Looper: DIY Pro Sound Equipment

A fun aspect of building with the Raspberry Pi is how easy it is to develop a custom version of unique equipment—like this Raspberry Pi-powered 4-track looper created by The Psychotenuse on YouTube. These projects often come at a lower cost, but when they don’t, they usually make up for it with additional features.

Not only did the maker show his project off, but you can also recreate it yourself by following the complete tutorial. Everything you need to develop your own loop station is shared and carefully explained in the instructions. The looper is used to mix music in real-time by recording audio tracks and looping them on command. Check out this demo to see exactly how it works:

The looper requires 8 buttons in total and 8 individual LEDs. The buttons are used to start and stop recording as well as start and stop when the audio track plays in a loop.

It’s worth noting that in this tutorial, ALSA Mixer is used. This used to be the default audio mixer for Raspberry Pi OS. As of December, it’s been changed to PulseAudio. Keep that in mind if you decide to make this project yourself and visit the Github repo for all of the files you need.
