Extended SourceWare Archive Group

XSWAG (Extended SourceWare Archive Group) is a revival project for the famous SWAG code archives for the Pascal programming language. This project is open to every Pascal/Delphi programmer who wishes to contribute to the global Pascal knowledge base. Current version (testing 0.9) features : - a reader program : allows users to browse through the code archives, organizes them by type and operating system and updates the archives from multiple XSWAG servers. - a server daemon : maintains a list of archives and provides updates to clients. - a creator program : to quickly make or modify an XSWAG archive file, add/remove sources and update sources info (os, compiler, architecture, contact info, author name, subject).

Scimark for Delphi Lazarus Free Pascal

Benchmark for scientific and numerical computing. http://math.nist.gov/scimark Some years ago, someone converted the sources to delphi. The result of that convertion can be found here: https://code.google.com/p/scimark-delphi/ I found some issues and tried to contact the author. Without success. That's why I decided to start a new repository here. Patches are welcome!
