    GnuCOBOL

    A collection of GnuCOBOL programs

    This is a collection of COBOL programs, in order to contribute, share and disseminate the GnuCOBOL (formerly OpenCOBOL) project: https://sourceforge.net/projects/open-cobol/ All programs are written by Juan Carlos Negrete, from middle 2018 as at date. Some GnuCOBOL programs could also have been created by other collaborators, in which case they are listed in the AUTHORS and THANK YOU files. Copyright 2018-2025 Free Software Foundation, Inc.

    L'objectif de ce projet est de créer un environnement de développement intégré moderne pour AS400; et déporté sur un environnement fenêtré Windows. La modernisation du poste du développeur n’existe pas seulement pour ce que l’on appelle les « nouvelles technos » telles que java, C#, service web … .Les projets de développement sur des technos plus anciennes comme l’AS400 ou MVS doivent aussi bénéficier de ces avancées. Le système AS400 est souvent déprécié des jeunes développeurs car son interface verte et noire 5250 rudimentaire en mode caractère rebute rapidement; et est bien moins attrayant et facile à prendre en main qu’un Eclipse, WinDev ou Visual studio. Pourtant, IBM fourni aux développeurs tous les outils nécessaires pour accéder à un hôte iSeries de l'extérieur (ODBC, JDBC).

    Smallest possible

    Smallest possible

    Smallest possible syntactically valid files of different types

    Smallest possible is a curated repository whose aim is somewhat playful yet useful: collecting the “smallest possible syntactically valid files” across a large variety of programming, scripting, markup, and binary file types. For example, the repository might include the minimal valid HTML file, minimal valid PDF, minimal valid executable, minimal valid image file, and so on. It serves both as a curiosity and as a utility for developers and testers who might need tiny stub files for testing tooling, parsing, or file-type handling. Because each file targets minimal syntactical correctness, the repository is valuable for edge-case testing (e.g., parsers handling smallest valid inputs). The project is open, community-welcoming (pull requests accepted) and carries a public-domain style waiver by the author. Although specialized, its uniqueness lies in spanning many file types and languages uniformly under the “minimal valid” idea.

    lixa

    LIXA, LIbre XA, is a free and open source XA transaction manager

    LIXA (LIbre XA) is an open source and free Transaction Manager implementing the distributed transaction processing "XA specification" and "TX (transaction demarcation) specification" according to the X/Open CAE Specification. LIXA implements even XTA: XA Transaction API, an innovative API that implements XA transactional context passing among different applications. LIXA is a Transaction Manager but it's not a Transaction Monitor: this is the distinguishing feature of the project. LIXA technology enables every application container, like a web server or a shell, to become a two phase commit application server. The client/server architecture of LIXA allows many application containers to share a single LIXA (state) server: this is ideal when horizontal scalability is a must and many identical application containers must refer to a single transactional environment. LIXA can be used with the C, C++, Java, Python and COBOL programming languages.
