BitKinex integrates the fuctionality of an innovative FTP, SFTP and WebDAV client for Windows.

Cadaver is a command-line WebDAV client for Unix. It supports file upload, download, on-screen display, namespace operations (move/copy), collection creation and deletion, and locking operations. (Ubuntu package)

Sitecopy is for easily maintaining remote web sites. The program will upload files to the server which have changed locally, and delete files from the server which have been removed locally, to keep the remote site synchronized with the local site with a single command. (Ubuntu package)

Pokud i po přečtení všech protiargumentů přeci jen věříte, že konec světa nastane, pak je nám líto. V tom případě:

Firebird is a relational database offering many ANSI SQL standard features that runs on Linux, Windows, and a variety of Unix platforms. Firebird offers excellent concurrency, high performance, and powerful language support for stored procedures and triggers. It has been used in production systems, under a variety of names, since 1981.

The Firebird Project is a commercially independent project of C and C++ programmers, technical advisors and supporters developing and enhancing a multi-platform relational database management system based on the source code released by Inprise Corp (now known as Borland Software Corp) on 25 July, 2000.

The Drizzle project is building a database optimized for Cloud and Net applications. It is being designed for massive concurrency on modern multi-cpu/core architecture. The code is originally derived from MySQL.

MariaDB is a database server that offers drop-in replacement functionality for MySQL. MariaDB is built by some of the original authors of MySQL, with assistance from the broader community of Free and open source software developers.

Percona Server with XtraDB is a backwards-compatible replacement for MySQL that is much faster and more scalable, easier to monitor and tune, and has features to make operational tasks easier.
XtraDB - Multiple Rollback Segments

OurDelta produces enhanced builds for MySQL 5.0 and builds for MariaDB 5.1, on common production platforms. James Purser of Open Source On The Air describes OurDelta as “a new distribution for MySQL”.
