Welcome to the new part of Free Messenger Saga (Signal, Tox, Matrix, Tor Messenger). It’s very good that in the modern world of Facebook, WhatsApp and Skype some peoples create new software for communication.
Ring – open source platform for text chat, voice and video communications and released under one of the best free license – GPLv3. All source code is available on Github. Linux client uses the GTK+ toolkit. Probably most of the Ring code was written by Savoir-faire Linux – free and open source software company based on Canada and France.
“Ubuntu” is an ancient African word, meaning “humanity to others”. Ubuntu also means “I am what I am because of who we all are”. The Ubuntu Linux distribution brings the spirit of Ubuntu to the software world.
Qubes OS – Linux Fedora-based Distribution focused on security through isolation with Xen virtualization. Qubes OS developed by Joanna Rutkowska; in this review I use latest version – 3.0. Also available installation DVD and LiveUSB. Basic hardware requirements – 64bit Intel of AMD CPU with VT-x/VT-d or AMD-v/AMD IOMMU technologies, minimum 4 GB RAM.
GNU Hurd – microkernel and part of GNU Project. Hurd means “Hird of Unix-Replacing Daemons”, Hird – “Hurd of Interfaces Representing Depth. Total recursion! Development started in 1990 (before Linux kernel) as part of plans to create fully free and open source operation system. Unlike the Linux kernel Hurd have a lot of system daemons (you can see it on video) run by GNU Mach microkernel and some specific system protocols. Popularity of Linux lowered Hurd’s priority, but project progress all this 25+ years.
