BlogTrader Platform is a free, open source stock technical analysis platform with a pluggable architecture that is ideal for extensions such as indicators and charts. BlogTrader Platform is built on pure java.
It supports parallel quote data retrieval from Yahoo! or ASCII text files, historical, intra-day, and real-time charts, and candle, bar, and line charts. It has a natural date/trading date view model. "MACD", "OBV", "ROC", "KD", "BIAS", "DMI", "RSI", "MTM", and "WMS" indicators and drawing of "Line", "Parallel", "Gann Angle", and "Fibonacci Line" are supported. You can easily write your own indicators.
Main features:
- Retrieve quote data in parallel from Yahoo! Finance, netfonds.se, or CSV files.
- Save quote data to local database (hsqldb).
- Adjust quote chart for splits and dividents if possibale (Yahoo! quote data only).
- Daily, Weekly, Monthly charts (Weekly, Monthly data are composed automatically from Daily data)
- Historical/Intra-Day/Real-Time Chart
- Real-time Ticker Board
- Update Daily, Weekly, Monthly Charts and their indicators automatically according to the newest tickers.
- Multiple quote-charts comparison
- Candle/Bar/Line
- Calendar/Trading date view
- Define indicators parameters separately for Daily, Weekly and Monthly charts, parameters can be saved as default or apply to all
- Add layer drawings separately for Daily, Weekly and Monthly. Save/Restore drawings.
- Carefully design for writing your own indicator easy, but in java (maybe will support scripts some day)
- Supports multiple platforms, includes windows, linux, macos, solaris, etc. (Java JRE 1.5 required)
- More to be come ...
Enhancements:

Simply Powerful ToolKit in short SPTK is a powerful widget toolkit based on the Fast and Light ToolKit (FLTK).
The goal of this library is to create the easy-to-use, compact and effective library of controls to extend the abilities of FLTK library.
It is geared for business-style application development with database support (ODBC). All the widgets support database connectivity. A special CDialog class makes editing database records very easy. Every widget can be connected to the field, and CDialog can be connected to the database table.
Most of the controls are database-bound. If you place them on the CDialog-derived window they can load and save information from/to database.
This is the first release version of my controls(widgets) library that was designed to work with FLTK. Im using it for about a year in the production project.
Enhancements:
- Fixed a bug in CField::asString() that cause returning an empty string for some non-empty fields.
- Added couple of small fixes for better error hanling in CRegistry.

SIMD Cross-platform headers is a cross- platform, cross-compiler, cross CPU C/C++ header collection that aids the creation portable vectorized (SIMD) C/C++ code.
SIMD Cross-platform headerst supports (or partially supports) x86 (MMX/SSE/SSE2) GCC and MSVC, PPC Altivec GCC and CodeWarrior, ARM GCC, and software-emulated SIMD.
NOTE: Code must be 16-byte aligned. Align to 16 when allocating memory.
X86/XSCALE (Intel) vs. PowerPC/MIPS
While the PowerPC and MIPS SIMD instructions take 2 source vectors and a destination vector, the Intel platforms only take a source and destination. Example:
PPC/MIPS can do:
C = A + B
X86 can only do:
A = A + B (or A+=B)
Code written either way will work on the X86, and still be faster than 387 math, but preserving the registers takes significant overhead (Disassemble the test program for an example. The prints preserve, the disassembly test does not.) For the fastest code between systems, write your SIMD math as the X86 expects, manually preserving SIMD variables.
At least GCC for PPC doesnt seem to have any issues figuring out how to deal with a source and destination memory address being the same.
Enhancements:
- Created file with some i386, GCC dialect

Cross Platform Toolkit Library (xtklib) is a C++ based framework for highly object-oriented cross-platform programming.
In particular, the library provides a full abstraction layer between its API and the main services offered by the underlying operating system(Thread, processes,GUI,Filesystem,etc.) plus a set of generic utilities (Strings,Data structures,etc.).
Unlike other famous libraries, xtklib makes full use of all features of C++ like RTTI, Templates, Exceptions thus obtaining a strongly object-oriented design with a Java-like sensation.
The library is composed by two main modules: "Base" and "Widgets". The target operating systems are Windows and Unix(Linux and BSD in primis) with a plan to move also towards other systems.
Main features:
- Use of modern C++ - use of many powerfull features offered by modern C++ like exceptions,RTTI,templates and namespaces allows faster development,improves code readability,and reduces programming errors.
- Strong Object-Oriented design - designed to meet requirements of modern software industry: modularity, low coupling, high cohesion,information hiding. Design patterns and advanced class hierarchies are extensively used in all the library.
- Ease of use - Clean and intuitive programming interface with a Java-like sensation.
- Complete - Features supported includes:
- Basic services: Thread, Synchronization, Filesystem access, Processes, Networking.
- Advanced services: I/O Streams, Logging.
- Debugging tools: Stack tracing, Memory Leak detection.
- Gui widgets (Work in progress): Windows,Frames,Layout managers,common controls,advanced controls.
- Generic utilities: complete data structures framework, String class with unicode support.
- Full unicode support: native support to unicode, conversion to/from different charsets.
- And many others: the list is too much long to enumerate all minor but extremely usefull features.
- Cross Platform - Supports various systems and compilers.
- XTKlib is known to work under:
- Windows XP (x86)
- Visual C++ versions 7.1, 8.0
- MinGW32
- Linux (x86, x86_64)
- GCC 3.4
- Compatibility with other platforms and compilers are not excluded.(If you can compile/use xtklib with a non listed compiler/platform let us know about that, thanks)
- Fast - Although performance are not the main goal of this library (exceptions and RTTI have a tradeoff in this meaning), code agility and execution speed are often taken in consideration during development, thus leaving a performance advantage compared to interpreted programming languages(eg. Java,C#) or scripting languages(eg. Python,Ruby,Perl).
Enhancements:
- This is the first release with a working "Widgets" module, although it has only basic features.
- This release is provided for testing and development only.

OpenPKG is a flexible and powerful software packaging facility, OpenPKG eases installation and administration of Unix software across several platforms. It primarily targets the Unix platforms FreeBSD, Linux and Solaris, but is portable across mostly all modern Unix flavors.
Consolidating different vendor approaches into a unified architecture, it assists in administration of large networks previously complicated by nonconformant systems. OpenPKG leverages proven technologies like Red Hat Package Manager (RPM)and neatly provides an additional system layer on top of the operating system.
It is a fully self-contained with minimal external dependencies(no RPM pre-installation required), and installs itself by means of a tricky bootstrapping procedure with minimal operating system intrusion. OpenPKG especially supports multiple installation instances on the same system.
Main features:
- Portable across major Unix platforms.
- Available for FreeBSD 4.11/5.4/6.0/7.0, NetBSD 2.0, Sun Solaris 8/9/10, Debian GNU/Linux 3.1, Fedora Core 4, RedHat Enterprise Linux 4, Novell SUSE Linux 9.3/10, Gentoo Linux 1.12.0, Mandriva Linux 10.2.
- Already known to work for IBM AIX 5.1, HP HPUX 11.11.
- Release 2.5 consists of 579 packages.
- Entirely based on Open Source software technology.
- Operating System interference minimized.
- Streamlined software packaging.
- Easy installation, updating and deinstallation of packages.
- Bundled with useful and secure package preconfigurations.
- Includes an abstracted and powerful run-command facility.
- Virtual hosting through multiple instances on a single system.
- Proxy packages for reusing packages across instances.
- Build-time package variations for maximum flexibility.
- Foundation to build self-contained environments.

- Fetch and send attachments
- Handle Message flags (attachments and importance)
- Display light mailbox folder hierarchy
Enhancements:
- This experimental release provides exchange account setup using the Evolution account wizard.
