Within this segment, the strongest sound is Matrix, an interesting open and decentralized standard for communication designed for interoperability in a similar way to the interoperability existing in the e-mail segment, Enabling real-time communication between users regardless of the customers or servers they use.

Currently, the standard and all its development is maintained by Matrix.org Foundation, a non-profit organization based in the United Kingdom.

Matrix has been developed with privacy and security in mind, taking into account the federation between servers, so that a user can communicate in any existing room securely, with end-to-end encryption, regardless of the server Where you have registered your account, and using any client of your choice.

There are also gateways to participate through messaging programs such as Telegram, discord or Slack, among others.

Matrix allows communication between users basically via text chat, audio calls and video calls, along with other possibilities.

In addition, it aims to surpass the relative success achieved by the standards SIP, XMPP and RCS trying to circumvent the obstacles that have prevented that the standards now mentioned have not been able to go to more.

Among the customers, the best known is Riot, also open-source. Those who do not want to create their own self-hosted Matrix servers, have the possibility to hire some of Modular.im’s plans to create their servers with a few clicks away, depending on their needs.

KDE’s Plasma Mobile Is Shaping Up Nicely on the PinePhone

Last month, we took a closer look at how UBports’ Ubuntu Touch mobile OS progressed on the PinePhone, thanks to a video shared by developer Marius Gripsgård.

FreeBSD vs. Linux Scaling Up To 128 Threads With The AMD Ryzen Threadripper 3990X

Last week I looked at the Windows vs. Linux scaling performance on the Threadripper 3990X at varying core/thread counts followed by looking at the Windows 10 performance against eight Linux distributions for this $3990 USD processor running within the System76 Thelio Major workstation. Now the tables have turned for our first look at this 64-core / 128-thread processor running on the BSDs, FreeBSD 12.1 in particular. With this article is looking at the FreeBSD 12.1 performance and seeing how the performance scales compared to Ubuntu 20.04 Linux and the Red Hat Enterprise Linux 8 based CentOS Stream. Read more
