KaOS 2021.10 Is Here as One of the First Linux Distros to Ship with KDE Plasma 5.23 Desktop

Filed under

In celebration of KDE’s 25th anniversary, the KaOS developers release KaOS 2021.10 with the latest and greatest KDE Plasma 5.23 desktop environment series, which also landed today. This makes KaOS one of the first GNU/Linux distributions to ship with KDE Plasma 5.23, following close on the heels of KDE neon.

Therefore, if you want to install and use the KDE Plasma 5.23 desktop environment on your personal computer right now, you can either download the KDE neon 20211014 release if you like Ubuntu-based distributions, or KaOS 2021.10 if you want an Arch Linux-inspired but independent distro. Both offer a rolling-release model where you install once and receive updates forever, including new KDE Plasma versions.

Happy Birthday Jolla!

Filed under

Ten years back from today, our super excited founding crew including myself (Sami Pienimäki), Marc Dillon, Stefano Mosconi, Jussi Hurmola, and Antti Saarnio, took the founding papers of Jolla Ltd to the Finnish Patent and Registration Office, and the story of Jolla started officially. Soon after this, many individuals from the former MeeGo team joined the Jolla company to give birth to Sailfish OS.
I say ‘officially’ for Jolla, since as most of you know, the story had already begun years before this in the vibrant and enthusiastic MeeGo team at Nokia, and the passionate community around it. Back in 2010, Nokia was on full speed to make MeeGo its primary smartphone operating system, but after a change in strategy, MeeGo was discontinued in February 2011.

Ubuntu 21.10 “Impish Indri” Is Now Available for Download, This Is What’s New

Filed under

Dubbed as the “Impish Indri,” Ubuntu 21.10 has been in development for the past six months and comes as an upgrade to the Ubuntu 21.04 “Hiruste Hippo” release, which will reach end of life on January 2022. Ubuntu 21.10 is supported for the next nine months, until July 2022, so it’s the obvious upgrade choice.

The biggest new feature of Ubuntu 21.10 “Impish Indri” is the GNOME 40 desktop environment. This is the first Ubuntu release to ship with a complete GNOME 40 desktop, as the Ubuntu 21.04 release only offered GNOME 40 apps on top of the GNOME 3.38 desktop environment.

Ubuntu Unity 21.10 Released to Keep the Unity7 Desktop Alive in 2021

Filed under

Ubuntu Unity 21.10 is here today as part of the upcoming Ubuntu 21.10 "Impish Indri" release, but Ubuntu Unity still doesn't have the "official flavor" status. However, that shouldn't stop you from using this great distribution on your personal computer if you still want to use the Unity desktop environment in 2021.

This release still uses the old Unity7 interface rather than the upcoming UnityX 10 desktop that the Ubuntu Unity team is developing for some time now as the successor of Unity7, which received new and updated indicators, and saw the migration of the glib-2.0 schemas to gsettings-ubuntu-schemas.

  • Why I only have one computer

    Assuming you’re more than just a consumer of online content, you probably have local files for things that are important to you: school work; in-progress projects; creative pursuits; family photos; a personal music collection; source code repos; saved memes–you name it. With more than one computer, you need to figure out a way to keep these files in sync, and good solutions are elusive.

    Cloud services are expensive and may compromise your privacy. Free non-cloud local sync services only work when both machines are on the same network. Any FOSS versions of these are unfortunately buggy and a chore to set up and maintain.

  • Tiny TV Tells The Temperature Tale | Hackaday

    Once upon a time, we would run home from the bus stop to watch Gargoyles and Brady Bunch reruns on the family TV, a late-1970s console Magnavox number that sat on the floor and was about 50% more cabinet than CRT. The old TV, a streamlined white Zenith at least ten years older, had been relegated to the man cave in the basement. It looked so mod compared to the “new” TV, but that’s not the aesthetic my folks were after. They wanted their electronics to double as furniture.

    This little TV is a happy medium between the two styles, and for us, it’s all about those feet. But instead of cartoons, it switches between showing the current weather and the top news headlines. Inside that classy oak cabinet is an LCD, an ESP32, and an SD card module. The TV uses OpenWeatherMap and pulls the corresponding weather image from the SD card based on time of day — light images for day, and dark images for night.

What New Features to Expect in the Coming Release of Fedora 35

Filed under
Red Hat

Twice each year, in April and October, the community behind Fedora releases a new major version of the extremely popular Linux distribution. Currently scheduled for October 19, 2021, the release of Fedora 35 is quickly approaching. Let’s take a look at what you can expect when you install or upgrade to the 35th incarnation of the world’s most popular bleeding edge Linux distribution.


Fedora 35 is tentatively scheduled to be released on October 19 with a fallback date of October 26 in case of any release-blocking problems. While we’d love to see Fedora 35 released as soon as possible, history shows that it’s more likely that the release will come on the later date.

You can currently download Fedora 34 or the Fedora 35 Beta release from the Fedora Project’s website. You’ll also find links to both current and beta versions of the many Fedora spins.

Best Spotify Alternatives For Linux

Filed under

Spotify is the most popular music streaming service. A Spotify free account grants access to a massive catalogue of songs, podcasts, and internet radio. But, if you’re a big fan of open-source software like me, you’ll want to check out these free and premium Spotify alternatives for Linux.

These Spotify alternatives not only give us access to a large collection of free music resources, but we can also use some of them to host our own streaming server.
Spotify does not enable you to host the software on your own server. Furthermore, the Spotify client for Linux is not developed by a dedicated team, so expect bugs and glitches with the official Spotify Linux client. In this case, you can look through the following list to see which music application you prefer for your Linux distribution.

Sitara-based LoRa gateway launches with serial-to-LoRa adapter node

Filed under

Embux’s “ELA-MG” LoRa gateway runs Linux on TI’s AM335x and offers a Semtech SX1272 LoRa module with -137dBm sensitivity plus GbE, USB, RS232, and RS485 ports. There is also an NB-IoT model and an “ELA-MA” serial-to-LoRa adapter for endpoints.

Nexcom announced a LoRa wireless gateway from its Embux subsidiary, which has previously manufactured products such as its i.MX6-based 3.5-inch EBC3A1-1G Y0 SBC. Like the SBC, the new ELA-MG gateway runs Linux on the aging Cortex-A8 architecture, this time in the form of a Texas Instruments Sitara AM335x SoC.

The ELA-MG incorporates Semtech’s SX1272 LoRa transceiver, which enables the gateway to transmit over 862 ~ 932MHz frequencies with up to 20dBm output power at rates of up to 18.2Kbps. Transmissions can achieve up to a 2 Km range, according to most citations, although the specs also say 2-5 Km.

Kernel: Paul E. Mc Kenney and New Stuff in Linux

  • Paul E. Mc Kenney: TL;DR: Memory-Model Recommendations for Rusting the Linux Kernel

    These recommendations assume that the initial Linux-kernel targets for Rust developers are device drivers that do not have unusual performance and scalability requirements, meaning that wrappering of small C-language functions is tolerable. (Please note that most device drivers fit into this category.) It also assumes that the main goal is to reduce memory-safety bugs, although other bugs might be addressed as well. Or, Murphy being Murphy, created as well. But that is a risk in all software development, not just Rust in the Linux kernel. Those interested in getting Rust into Linux-kernel device drivers sooner rather than later should look at the short-term recommendations, while those interested in extending Rust's (and, for that matter, C's) concurrency capabilities might be more interested in the long-term recommendations.

  • Cluster Scheduler Support Queued Ahead Of Linux 5.16 - Phoronix

    Cluster scheduler support has been queued up for landing in the Linux 5.16 kernel for AArch64 and x86_64 systems for improving the CPU scheduler behavior for systems that have clusters of CPU cores. The cluster scheduler support in this context is about enhancing the Linux kernel's scheduler for systems where sets of CPU cores share an L2 cache or other mid-level caches/resources. This cluster scheduler work stems from work by HiSilicon and Huawei aiming to improve the Linux performance for the Kunpeng 920 server chip. That HiSilicon SoC has six or eight clusters per NUMA node with four CPU cores per cluster and a shared L3 cache. With the cluster scheduler patches they were able to enhance the overall performance of the system and also improve the efficiency.

A new major version of Firefox 93.0 added support for the optimised image format AVIF, which offers a significant file size reduction as opposed to other image formats. The browser also improved web compatibility for privacy protections and fixed more than a handful of Common Vulnerabilities and Exposures. Thunderbird 91.2.0 addressed many of the same CVEs, fixed some issues with the calendar and fixed the new mail notifications that did not properly take subfolders into account. The 5.9 version of text editor nano added syntax highlighting for YAML files and fetchmail 6.4.22 added a few patches, addressed a CVE related to an IMAP connections and now highlights being compatible with OpenSSL 1.1.1 and 3.0.0. The new major version of postgresql 14 provided improvements for heavy workloads, enhanced distributed workloads and added a couple more predefined roles like pg_read_all_data, pg_write_all_data and pg_database_owner. Other packages to update in the snapshot were GNOME’s document viewer evince 41.2, Flatpak 1.12.1, graphics library gegl 0.4.32, glusterfs 9.3 and many RubyGems and YaST package updates.
