• 12 Best Free and Open Source WebDAV Servers - LinuxLinks

  WebDAV (Web Distributed Authoring and Versioning) is a protocol that allows users to access and manage files stored on a remote server. It is commonly used for web-based file sharing and collaboration, as it allows users to upload, download, and manage files directly from a web browser or file manager.

  It’s based on HTTP (Hypertext Transfer Protocol) and uses the same basic communication methods, but adds additional features and functionality specifically designed for file management. These features include support for file locking, collections, and metadata.

  This roundup picks our favourite WebDAV servers for Linux. Only free and open source software is eligible for inclusion here.

• KSudoku - popular numeric puzzle game - LinuxLinks

  When you start a game, you can choose from several Sudoku types and sizes. You can then have KSudoku generate a puzzle for you to solve or you can start with an empty board and enter in a puzzle from another source, such as a newspaper, then get KSudoku to check it and maybe solve it.

  There are many variations of Sudoku in existence and KSudoku provides a good selection of them. The most common type, Standard Sudoku, has a 9×9 square grid and uses Arabic numerals 1 to 9 as symbols. The grid has 9 rows and 9 columns and is divided into 9 blocks of 3×3 squares. The problem is – each symbol can only be used once per row, column or block.
