Action! Programming Language

Action! is a programming language for the Atari 8-bit family of microcomputers. It features an integrated editor, a debugger, and a 6502 compiler. Action! was created by Clinton Parker and released on cartridge by Optimized Systems Software (OSS) in 1983. Its syntax is similar to that of ALGOL 68. Action! is significant for its high performance, which allows games and graphics demos to be written in a high-level language without the use of hand-written assembly language code. Action! language constructs were designed to map cleanly to 6502 opcodes. In 2015, Clinton Parker released the Action! 3.6 source code to the public under the terms of GPL. This project is intended to preserve the Action! source code, provide fixes for known bugs, and add new features in version 3.7.

qxotica - tools for qooxdoo

Includes a package for the Lazarus IDE that adds items to the File | New dialog. Selecting "qooxdoo JavaScript App" creates either a single-page or two-page master-detail qooxdoo app and a Lazarus project for managing and editing the app's JavaScript files. Selecting "qooxdoo JavaScript Page" adds a page to the app and to the Lazarus project. Can also "compile" (run generate.py) from within Lazarus - if a syntax error is detected, the code editor jumps to the JavaScript file and line where the error is located. Also includes full source code for the Unicodum demo app. This is a Unicode viewer consisting of a qooxdoo-based mobile client and a choice of Pascal (FCGI) or PHP server app.

Corrupt Extractor for Microsoft Office

Corrupt Office 2007 Extractor will extract the text/data from corrupt docx, xlsx, and pptx files where the respective MS Office files error out and refuse to open. In advanced mode the program can fix the zip structure of "Office Open XML" format files, a step which I now recommend despite our dissuasive blurb which comes up when you start that function. Advanced mode also allows recovering images and includes is a basic editor for editing the corrupt XML subfiles. Additionally I recommend trying some of my other programs on Sourceforge which help with corrupt office files using different algorithms than this present program: Savvy DOCX Recovery, S2 Recovery Tools for Word, Corrupt XLSX Salvager, S2 Recovery Tools for Excel and Corrupt PPTX Salvager. Also take a look at these free corrupt Word repair programs: http://wordcorruptdocchecker.codeplex.com/ and https://support.microsoft.com/en-us/kb/2528942 (featuring a Microsoft Mr. Fixit App).

nik4nix

Main idea here is that you can use Nik Plugins stand-alone without officially supported 3rd party host application (Lightroom, Photoshop, Spark, Portfolio). On Windows or Linux. Source code can be compiled natively for Linux or for Windows with Lazarus IDE. The program is dedicated to Ubuntu users, where you can install Nik Collection using wine. On Ubuntu you can either use native Linux version, or native Windows version running via wine. In fact, currently the latter is recommended, because there are some UI glitches related to gtk widgetset if you compile for Linux - the UI looks better in native Windows version (this can be fixed in the future). Even if you use native Windows version on Linux via wine, the app will be aware of wine and will still be integrated with your Ubuntu desktop and will be integrated with supported apps on it, like Gimp, Pinta, Darktable, Nautilus, etc. It will still talk to your shell, and provide all the integration with your Linux.
