Tennis - stylish terminal viewer for CSV, JSON and SQLite data
The application concentrates on making tabular information readable within the available terminal space. Its layout engine calculates column widths, truncates content where necessary and adjusts the presentation to accommodate different data types. This is particularly useful when inspecting datasets containing numerous columns or fields with varying lengths.
Tennis is suitable for developers, system administrators and data analysts who frequently examine structured files. It offers lightweight data exploration alongside formatting controls that make tables easier to interpret. Users can select particular columns, rearrange information and inspect representative data without modifying the underlying files.
The utility also includes colour schemes and presentation options for producing readable output in different terminal environments.

Aerofoil - modern port of the classic Glider PRO game
The objective is to guide a paper airplane through the rooms of a house, using air currents from floor vents to stay airborne. Players must avoid furniture and other obstacles while collecting stars scattered throughout the levels. The simple controls disguise a game that requires careful navigation and timing.
Aerofoil recreates the original game’s distinctive appearance and gameplay while making it accessible on modern systems. It includes the houses from the original CD-ROM edition, together with facilities for creating and playing custom houses. These can range from relatively simple layouts to elaborate environments containing hundreds of interconnected rooms.

Spark NLP - scalable natural language processing library
The library combines traditional linguistic analysis with modern deep learning techniques. It supports a broad collection of pretrained models that can be incorporated into workflows without requiring every model to be trained from scratch.
Spark NLP is used for tasks ranging from identifying entities in documents to classifying text, translating languages and generating natural language. Its integration with Apache Spark allows processing to scale beyond a single machine, while interfaces for Python, Scala and Java make it accessible to different development environments.

Find Security Bugs - static security analysis for Java applications
The tool is particularly useful for auditing web applications, Android applications and projects that use popular Java frameworks. It extends the capabilities of SpotBugs with security-specific detectors and data-flow analysis, helping developers identify problems before applications reach production.
Find Security Bugs can be incorporated into existing development workflows, allowing security checks to run alongside other code quality assessments. Its findings provide developers with information about the underlying weakness and references to established security classifications.

Stacer (fork) - Linux system optimizer and monitoring tool
Originally developed by Oguzhan Inan, the application has been continued by QuentiumYT. The maintained fork uses Qt 6 and retains Stacer’s approach of providing system information, monitoring and administrative controls through a series of dedicated pages.
The application is intended for desktop users who prefer graphical tools to managing services, processes and system maintenance from the terminal. Its dashboard provides a convenient starting point, while the other sections offer more detailed controls for investigating performance problems and keeping a Linux installation tidy.

3FS - high-performance distributed file system
3FS is designed for workloads that need both high aggregate throughput and efficient random access. These include preparing large datasets, supplying training samples to accelerators, saving model checkpoints and retaining intermediate data produced during inference.
Its architecture separates metadata management from storage services and uses strong consistency mechanisms to simplify coordination between applications operating on the same datasets.

Linux Candy: ShimeLinux - animated desktop pets for Linux
ShimeLinux falls firmly into the latter category. It brings little animated characters, known as Shimeji, to your desktop. They wander around, climb, sit down, and generally make themselves at home.
The software is a port of Shimeji-ee for Linux and BSD. The developer says characters made for the latest version of Shimeji-ee should work, so there’s scope to give your desktop some different personalities.
Kubus - graphical Kubernetes cluster management
Kubus keeps its management interface local rather than requiring a dashboard deployed inside the cluster. It combines resource browsing with troubleshooting facilities, including log inspection, interactive terminals and performance monitoring.
The application is particularly useful for developers and administrators who regularly move between development, staging and production Kubernetes environments.

Coronet - crown-placement logic puzzle game
The game requires logical deduction rather than speed or quick reactions. Each placement affects the available positions elsewhere on the board, so players must consider several restrictions simultaneously to arrive at a valid solution.
Coronet provides simple graphical controls for placing crowns and marking squares that cannot contain one. These markings help players keep track of their deductions as the puzzle progresses. Incorrect placements are highlighted, making it easier to identify conflicts with the rules.
