High-speed, 3D-friendly, TightVNC-compatible remote desktop software
TurboVNC is a high-performance, enterprise-quality version of VNC based on TightVNC, TigerVNC, and X.org. It contains a variant of Tight encoding that is tuned for maximum performance and compression with 3D applications (VirtualGL), video, and other image-intensive workloads. TurboVNC, in combination with VirtualGL, provides a complete solution for remotely displaying 3D applications with interactive performance. TurboVNC's high-speed encoding methods have been adopted by TigerVNC and libvncserver, and TurboVNC is also compatible with any other TightVNC derivative. TurboVNC forked from TightVNC in 2004 and still covers all of the TightVNC 1.3.x features, but TurboVNC contains numerous feature enhancements and bug fixes relative to TightVNC, and it compresses 3D and video workloads much better than TightVNC while using generally only 5-20% of the CPU time of the latter. Using non-default settings, TurboVNC can also be made to compress 2D workloads as "tightly" as TightVNC.
A collection of packages providing extra functionality for GNU Octave
Octave-Forge is a central location for collaborative development of packages for GNU Octave. The Octave-Forge packages expand Octave's core functionality by providing field specific features via Octave's package system. See https://octave.sourceforge.io/packages.php for a list of all available packages. GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Refer to https://www.octave.org for more information.
Computer Algebra System written in Common Lisp
Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. For example, Maxima solves x^2-r*x-s^2-r*s=0 giving the symbolic results [x=r+s, x=-s]. Maxima can calculate with exact integers and fractions, native floating-point and high-precision big floats. Maxima has user-friendly front-ends, an on-line manual, plotting commands, and numerical libraries. Users can write programs in its native programming language, and many have contributed useful packages in a variety of areas over the decades. Maxima is GPL-licensed and largely written in Common Lisp. Executables can be downloaded for Windows, Mac, Linux, and Android; source code is also available. An active community maintains and extends the system. Maxima is widely used: annual direct downloads exceed 300,000. Many other users receive it through secondary distribution.

Real-time frameworks/RTOS based on active objects & state machines
Real-time frameworks/RTOS for building responsive and modular real-time embedded software as systems of active objects (concurrent state machines). The QP family consists of QP/C, QP/C++, and QP-nano frameworks, which are all strictly quality controlled, superbly documented, and commercially licensable. The behavior of active objects (a.k.a. actors) is specified in QP by means of hierarchical state machines (UML statecharts). The frameworks support manual coding of UML state machines in C or C++ as well as automatic code generation by means of the free QM modeling tool. All QP frameworks can run on bare-metal MCUs, completely replacing a traditional RTOS. Ports and ready-to-use examples are provided for major embedded CPUs, such as ARM Cortex-M, ARM7/9, MSP430, as well as Arduino and mbed. QP/C and QP/C++ can also work with a traditional RTOS/OS, such as ThreadX, FreeRTOS, embOS, and uC/OS-II as well as Linux (POSIX), Windows.

Scientific/engineering firmware repurposing HP business calculators!
This project has created scientific firmware for the HP-20b and HP-30b business calculators. The WP 34S turns either of these calculators into a powerful keystroke programmable scientific device. According to our customers, it's the most powerful and fastest RPN scientific pocket calculator ever built. The WP 34S is alive and stable since 2011. We have succeeded in satisfying the most picky users - read about their experiences on http://www.hpmuseum.org/forum/forum-8.html. Find the Owner's Manual v3.2 at https://www.createspace.com/4106229 In 2014, we've updated the WP 34S to version 3.3. Our customers confirm its documentation is excellent and comprehensive (see feedback); an updated printed edition is available from https://www.createspace.com/6329314 since June 2016. We have also produced the WP 31S which is derived from the WP 34S source code. This is an entry-level scientific calculator. Its printed manual is available from https://www.createspace.com/4773370
Linux Studio Plugins Project
LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. Also standalone plugins for JACK are provided since version 1.0.8. The basic idea is to fill the lack of good and useful plugins under the GNU/Linux platform. After some contributions to other open source projects the decision was made to implement separate and independent plugin distribution.
Calendar App To Perform Date-Time Related Functions
Github - https://github.com/shivammathur/C-CPP-Calendar C-CPP Calendar app is a easy to use app to do all the functions that a calendar is used for. The app is very handy and extremely better than using a physical calendar. It is available as both x86 and a x64 versions. The app can display day of any date in the Gregorian calendar (1753 - 9999). It can be used to display calendar of a month of a year. The most awesome feature is that it displays the calendar of a year in a well formatted layout like a paper calendar and also generate a text file for the same. It is very handy when it displays the dates in a month on which a day occurs in that month. C-CPP Calendar provides personalized user account with password protection (MD5 based). C-CPP Calendar is compatible with Windows 2000 up-to Windows 10. Though no official support is there for Linux or mac, it was tested to be work
