  • What is Linux SSH?

    “Linux Secure Shell, or SSH, is a protocol used by Linux computers to access remote computers and execute commands securely. It is a replacement for rlogin and rsh. Thus, SSH provides encrypted and secure communications between untrusted hosts over an insecure or untrusted network. Also known as Secure Socket Shell, this protocol is a security application for Linux users connecting to remote servers. The framework allows users to transfer files, run command lines and graphical programs, and create secure virtual networks over the internet. The framework has an SSH command to secure remote connections and data transfers between clients and hosts. The utility ensures encryption of all communications.t The command works by transferring client inputs to the host. Once done, the command returns the output from the host to the client and often executes through IP/TCP port 22. This encrypted connection is also used in port forwarding, Linux server, tunneling, and many more.”

Microsoft to face new antitrust scrutiny in Germany

Germany's competition watchdog is set to look into whether Microsoft should come under the scope of new rules that allow the country to rapidly prohibit anti-competitive conduct, according to people familiar with the matter. Two individuals close to the matter told POLITICO that the German Cartel Office has prepared a draft decision to launch proceedings under Section 19a of the German Competition Act. The move will attempt to determine whether Microsoft should be designated as having “paramount significance for competition across markets.” If it is designated under the scope of the rules, Germany’s competition regulator will be able to intervene rapidly to ban certain anti-competitive conduct — including self-preferencing abuses and the pre-installation of services.

  • Midichlorians in the blood: Summer Releases

    The first two applications, kmetronome and kmidimon, are now over fifteen years old and are only available for Linux. These two new versions are simply bug fixes, with no new features. But it is interesting to note that in FlatHub they are already based on Qt6 and supporting both Wayland and X11, although the packages in AppImage format still use Qt5. The chances of finding these applications in the official repositories of Linux distributions are slim. In fact, kmidimon was removed from the official Debian repositories with some lame excuse, and it is unlikely to be included again. I can't do anything about it, so please: direct complaints where they belong. Or use the new available distribution formats or the unofficial repositories, like Debian Multimedia, which includes the three mentioned applications and many others. The other app, dmidiplayer, is much newer and cross-platform. It is the successor to Kmid2, the KDE karaoke application that I rewrote many years ago. In this new version the most remarkable new feature is the persistent configuration of the songs. This is a feature that was already present in the old Kmid2 and that allows you to store the tempo, general volume, pitch transposition, and MIDI channel settings for each song, which will be applied when it is played again in the future. The other novelty is the individual volume adjustment for each MIDI channel, something that was not possible in Kmid2.
