High Visibility Calculator is a high visibility calculator for people with disabilities.

Large buttons with bold text are easy to push for people with motor control or vision problems.

Audiality is a scalable and portable audio engine for music and sound effects. It is intended to play equally well in studios and inside games, in order to serve as a flexible tool for content creation, and for use in the final product.

Audiality uses MIDI files in combination with scripting and modular synthesis, to minimize file sizes and maximise flexibility. It is very portable, and supports both integer and floating point processing modes.

Scalability has been a major priority from the start. The current version will run on very low end Pentium systems, but can also produce high quality audio on more powerful hardware.
The main goal for the future is to extend the scalability of Audiality well into the range of serious home and professional studio use. The idea is to provide total control, a wide range of features, tools for fast and effective creation of original sounds, and excellent audio quality.

Qute 3++ (custom mod) 1.4.7.20090313 offers you a plain and unobtrusive theme for Firefox with clear, colorful icons. This is recreated from the original Qute 3 one, to work on Firefox 3.0 and 3.1 nightlies.

Enhancements: Not many changes in this version, updated the base files to the latest 3.1 branch nightly build, and updated the compat. to include b4pre.

Requirements: Mozilla Firefox

SimCList project is a high quality C library for handling lists.
SimCList is available for free, under restrictions imposed by the BSD license.
SimCList API is good because:
- it is simple, yet powerful
- it makes elegant and consistent use of information hiding
- it abstracts the actual data type to store
- it is fairly total
The library itself is very performant and makes a good compromise between performance in terms of time and space:
- insertion is O(n) [typically n/8]
- extraction and deletion are O(n) [typically n/8]
- iteration is O(1)
- sorting is always O(n logn), without worst case
Thread safety
The SimCList library is thread safe, meaning that many threads can run SimCList operators on different lists concurrently without hurt, or also read operations on the same list.
However, of course, no safety guarantee is made for performing concurrently write+write or read+write operations on the same list (eg: insertion, deletion, sorting, ...). For performance and portability reasons, protecting such operations from concurrency is left to the library adopter.
Performance
SimCList has been designed with ease to use and performance in mind. There is some example factors that have been taken into account, and against which the code has been optimized when implementing SimCList:
- overhead of function calls
- cache locality
- number of branches, possible CPU stalls or pipeline flushes
- dynamic memory allocation weight on the OS
- other mathematic/probabilistic optimizations for avoiding worst-case or improving average case behaviours in algorithms
Many parts of SimCLists code have been deeply improved with profiling analysis.
Enhancements:
- Transparent inclusion in C++ applications is natively supported.
- Sentinels are used to improve performance on list traversals.
- A problem was fixed with list_insert_at, which could output inconsistent lists when inserting into even-sized lists in position 0.

Intercom is a simple voice over IP (VOIP) utility. It supports various audio codecs and sample rates enabling the user to choose between high quality audio or lower speed data transfers. Intercom is a console utility with a command-line interface.

The primary reason I wrote Intercom was because though the VOIP solutions available were quite flexible and useful, most if not all only supported 8k audio conversations. Though this is adequate for lower speed connections, a high-speed connection can usually do much better and the quality improvement is quite substantial.

If you are not familiar with installing a GNU utility, please read through the INSTALL file located in this directory. If you are familiar with the standard UNIX install procedure, the following steps should get you up and running.

./configure
make

GNU/Linux Desktop Testing Project (GNU/LDTP) is aimed at producing high quality test automation framework and cutting-edge tools that can be used to test GNU/Linux Desktop and improve it.
GNU/Linux Desktop Testing Project uses the "Accessibility" libraries to poke through the applications user interface. The framework has tools to generate "AppMap" by reading through the user interface components of an application. The framework also has tools to record test-cases based on user-selection on the application.
GNU/LDTP core framework uses "AppMap" and the recorded "test-cases" to test an application and gives the status of each test-case as output.
As of now, GNU/LDTP can test any GNOME application which are accessibility enabled, Mozilla, OpenOffice.org, any Java application (should have a UI based on swing) and KDE 4.0 applications based on QT 4.0 (based on the press releases by KDE).
We encourage you to join the project and help us to create robust, reliable and stable test tool/framework for Linux Desktops.
Main features:
- LDTP concepts are derived from Software Automation Framework Support
- LDTP supports verification of actions performed (GuiExist, VerifyState, etc) - API Reference
- Writing test scripts are very easy, the script writer need not know about the object hierarchy
- CPU / Memory performance monitoring of application-under-test can be measured - Class pstats
- From the XML log, we can gather HTML report using XSLT
- Group based execution, which provides precise control on the flow of test-script execution - Gldap XML
- Scripts can be written as a reusable component and for that the datas can be stored / retrieved in XML - Data XML
- User-friendly Text Editor with syntax highlighting for generating and grouping test data Howto use LDTP Editor
- Objects are identified both statically and dynamically
Enhancements:
- Now automation scripts can be written without using time.sleep.
- A particular object and its child can be remapped in a window.
- Memory leaks were fixed.

3ivx is an MPEG-4 toolkit that supports MPEG-4 Video, MPEG-4 Audio and the MP4 file format. 3ivx D4 4.5 allows video and audio to be compressed to a fraction of its original size while maintaining high image quality.

You can store over 2 hours of near DVD quality audio and video on a single CD-ROM or stream near DVD quality video over a cable modem or DSL modem.

Supported File Formats:

- Input Files: 3GP, AAC, DivX, MOV, MP4
- Output Files: AVI, MOV, MP4

Why should I install 3ivx?

The 3ivx decoder plays back most MPEG-4 files (including MP4, M4A, 3GP and MOV files) with MPEG-4 AAC Audio and MPEG-4 Video (such as DivX 3, 4 and 5, Apple MPEG-4, Philips MPEG-4 and XviD) using Windows Media Player or other compatible players. The Audio Decoder can play back MPEG-4 Multi-Channel High Efficiency AAC including audio encoded by Nero AAC and iTunes.

The 3ivx encoder produces industry-leading compact high quality MPEG-4 Audio and Video and is distributed as a plug-in for QuickTime as well as plug-ins for Video for Windows and DirectShow.

This allows you to encode MPEG-4 Audio and Video in AVI, MOV or MP4 files with the encoding application of your choice.
