    DistroClone Backup & Restore Incremental rootfs backup and restore

    DistroClone Backup & Restore In the development of SysLinuxOS, one recurring need was a reliable way to snapshot and restore a system quickly — not just for users, but also during testing and ISO development. That is how DistroClone Backup & Restore was born: a graphical, incremental backup tool designed specifically for Debian-based systems. It is the companion utility to DistroClone Live ISO Builder, and both tools will ship together as part of the SysLinuxOS toolchain in upcoming releases. They are designed to work independently, but their real strength emerges when used together — something I will cover in a future article. What DistroClone Backup Does DistroClone Backup & Restore is a GTK/YAD-based graphical frontend that creates and manages backups of the system root filesystem (rootfs) across Debian-based distributions such as: Debian Ubuntu Linux Mint / LMDE Elementary OS Zorin OS SysLinuxOS and derivatives

    Tapper

    Keyboard layout switcher for X Widow System and Wayland

    Тapper — keyboard layout switcher for X Window System and Wayland. Tapper runs in background, when an assigned key is tapped, Tapper activates the corresponding keyboard layout. "Tap" means that a single key is pressed and quickly released, so (1) no other keys are pressed at this time, and (2) period between pressing and releasing is shorter than keyboard repeat delay (usually it is 0.5 s, but it depends on desktop settings). Tapper key feature is using modifier keys for switching keyboard layouts without losing modifier's functionality. Tapper works for GNOME, GNOME Classic, Cinnamon, i3, KDE, LXDE, LXQt, Mate, Ubuntu, Xfce desktops. There are prebult RPM packages for Fedora, Mageia, OpenMandriva, openSUSE, source tarball for configure && make is also available. Tapper is free software.
