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).

I am planning to release Chepersy 2 as a separate project someday, but it will not be compatible. I am truly sorry, but there were too many unstable hacks, I failed to reproduce their behavior. The future version will support 64-bit Intel and ARM platforms, will support fpc 3.x and will be based on reference counting (TInterfacedObject) A simple object database system for FreePascal. The persistence component features a powerful version compatibility system. Open architecture: you must manage some aspects by yourself according your needs. NOT compatible with fpc 3.x.

CodeSnip

CodeSnip is an open source code bank for storing and viewing code snippets. It not only manages, displays and manipulates your own code snippets but it can also incorporate snippets downloaded from the online DelphiDabbler Code Snippets Database. > CodeSnip's source code is now developed over on GitHub: https://github.com/delphidabbler/codesnip Designed with Pascal code in mind, CodeSnip enables Delphi or Free Pascal code snippets to be test-compiled with any installed Delphi or Free Pascal compiler and results to be reported. Use this feature to validate the syntax of code without switching to your compiler. Compilable Pascal units containing selected snippets can be generated. Code in other languages can be stored in CodeSnip although the source file generation and compiler checking features will not be available. Compilable Pascal units of selected snippets can be generated. Selected snippets can also be exported and shared with other CodeSnip users.

LibreAquarium

SME LibreAquarium is an Aquarium management system with a Simulation Model Engine (SME) that makes a prediction of the possible measurement values for the different pollutants that affect to these aquatics systems (NO3,PO4, Fe). The simulator consults the recorded analysis to calculate a prediction of the NO3, PO4, Fe, that the these aquatic system produce. It also uses a central (fish, plant and invertebrates) database to check if the actual parameters are Ok, depending on the species that live in the Aquarium. With all the records, the Simulation Model predicts the algae risk too (low,medium,high) and the algae type(green,cyanotic.) using the Redfield coefficient. Appart from that, the program tries to bring another modest contribution to Open Source Software and the World of Aquariums. SME LibreAquarium helps to daily maintenace of the aquarium with habitants control(fishes,plants, invertebrates), expenses, statistics, alarms, etc.

m6811dis

The M6811 Code-Seeking Disassembler is a command-line tool that lets you enter known starting vectors for a given code image for the 6811 micro. It will disassemble the code and follow through branches to assist in the separation of code and data. Its companion Fuzzy Function Analyzer uses DNA Sequence Alignment Algorithms to locate similar code in multiple binaries, facilitating reverse-engineering. Originally written to analyze code from GM automotive engine controllers, but is useful anywhere a 6811 micro is being used. Version 1.0 was written in Borland Pascal in April 1996, and updated to v1.2 in June 1999. It was later rewritten to C++ in July 1999 through Jan 2000. While it's been freely available since its creation, it's being released here as an open-source project so the world can better use it as it sees fit. Version 2.0 is completely reworked in 2014 to compile and run with GCC and STL to make it fully portable and accessible to all computer platforms.
