• AetherTune – Terminal Internet Radio Player Review

  AetherTune is a terminal internet radio player written in Rust. It combines Radio Browser station discovery with an audio visualiser, song log, and stream information. Version 0.12.0 also adds support for Subsonic-compatible music servers. This is free and open source software.

• Rat Commander - feature-rich two-panel file manager

  Rat Commander has a particularly capable built-in viewer. It handles text, hexadecimal data, Markdown, CSV and TSV files, images, audio, executables, certificates and 3D models. It can also display Git blame information and follow growing files in a similar fashion to tail -f. The integrated editor offers syntax highlighting, search and replace, undo and redo, hexadecimal editing, spreadsheet-style CSV/TSV editing, and syntax checking for JSON, TOML, YAML and XML.

  Remote filesystems can be accessed using SFTP, SCP, FTP and FTPS. ZIP, tar and 7z archives can be browsed and modified, while formats including DEB, RPM, ISO, SQLite, JSON and TOML can be explored using the same directory-oriented interface.

  This is free and open source software.

• PowerDevil - power management service for KDE Plasma

  PowerDevil is the power management service used by KDE Plasma. It works behind Plasma’s Power Management settings and coordinates desktop behaviour with the system’s available power-management facilities.

  Rather than being a general hardware configuration utility, PowerDevil concentrates on session power policy. It reacts to user inactivity, battery conditions and hardware events, and cooperates with other Plasma components where responsibilities overlap. On Wayland, some display and activity-related work is handled by KWin while PowerDevil remains responsible for the wider power-management policy.

  This is free and open source software.

• SynFlow - visualize genome alignments and structural variation

  SynFlow is a web application for exploring alignments and structural differences between genomes. It works with output produced by SyRI, the Structural Rearrangement Identifier, and turns those results into interactive visualizations of synteny and genomic rearrangements.

  The software is useful when comparing related genomes where a simple sequence-level browser does not clearly convey large-scale structural differences. Multiple comparisons can be chained together, allowing users to follow structural relationships through a series of genomes rather than being restricted to a single reference/query pair.

  This is free and open source software.
