OpenFOAM - The Open Source CFD Toolbox. OpenFOAM is a generic, programmable software tool for Computational Fluid Dynamics (CFD). For more information, go to
OpenFOAM is a free, open source CFD software developed primarily by OpenCFD Ltd since 2004, distributed by OpenCFD Ltd and the OpenFOAMFoundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to acoustics, solid mechanics and electromagnetics.
OpenFOAM+ uses the OpenFOAM Foundation version as a common code base, and offers wider functionality and platform support. Its purpose is to accelerate the public availability of new features which are sponsored by OpenCFD’s customers and contributed by the OpenFOAM community
It is independently tested by ESI-OpenCFD's Application Specialists, Development Partners and selected customers. It is supported byESI'sworldwide infrastructure, values and commitment.
Quality assurance is based on rigorous testing. The process of code evaluation, verification and validation includes several hundred daily unit tests, a medium-sized test battery run on a weekly basis, and large industry-based test battery run prior to new version releases. Tests are designed to assess regression behaviour, memory usage, code performance and scalability.
OpenFOAM+ releases are scheduled every six months in June and December.

Brain Workshop is a Python implementation of the Dual N-Back mental exercise. This exercise is the only mental activity that has been scientifically shown to improve your short-term memory (working memory) and fluid intelligence.
Brain Workshop implements this dual n-back task, and allows you to attempt to improve your own working memory and fluid intelligence. The dual n-back task involves remembering a sequence of spoken letters and a sequence of positions of a square at the same time, and identifying when a letter or position matches the one that appeared earlier. Brain Workshop can closely replicate the conditions of the original study. In addition, it also includes optional extended game modes such as Triple N-Back and Arithmetic N-Back for extra challenge. It also includes features such as statistics tracking, graphs andconfigurability.
Anecdotal evidence from users suggests that the dual n-back task can also enhance focus and attention and may help improve the symptoms of ADHD/ADD.
Brain Workshop works on Windows, Mac OS X and Linux.
Since its initial release in August 2008, Brain Workshop has been downloaded over 775,000 times.
New to Dual N-Back
See this Wired article for an introduction to the Dual N-Back exercise and its benefits.

Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.
Qucs stands for Quite Universal Circuit Simulator. So far Qucs is not yet finished, but it is already packed with features. Take a look at the screenshots to get a feel for what it can do.
Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit. After that simulation has finished you can view the simulation results on a presentation page or window.
Qucs, briefly for Quite Universal Circuit Simulator, is a circuit simulator with graphical user interface (GUI). The GUI is based on Qt® by Digia®. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Harmonic Balance analysis, noise analysis, etc.
Qucsator, the simulation backend, is a command line circuit simulator. It takes a network list in a certain format as input and outputs a Qucs dataset. It has been programmed for usage in the Qucs project but may also be used by other applications.
The Qucs GUI is well advanced and allows setting up schematics and presenting simulation results in various types of diagrams. DC, AC, S-parameter, noise and transient analysis is possible, mathematical equations and use of a subcircuit hierarchy (with parameterised subcircuits) are available. Qucs can also import existing SPICE models for use in your simulations.
While Qucs is well developed, we still strive to improve the project, and will always welcome offers of help. Qucs doesn't just need help with programming, it also needs graphics, high quality example schematics, tutorials for the website and lots more.
Qucs comes with a huge array of components and models including HICUM, BSIM2, BSIM3, and soon BSIM6. It also provides many semiconductor based components and models such as OpAmps, Diodes, MOSFETs, PMOSFETs and many more. Some example schematics can be found here which demonstrate some of the abilities of Qucs, and many more examples are provided with the program.

The Pure Data (short Pd) project on SourceForge unifies the extensions (or externals) written for the Pure Data Graphical Computer Music System written by Miller Puckette with contributions from many others.
A new software system, called Pure Data, is in the early stages of development. Its design attempts to remedy some of the deficiencies of the Max program while preserving its strengths. The most important weakness of Max is the difficulty of maintaining compound data structures of the type that might arise when analyzing and resynthesizing sounds or when recording and modifying sequences of events of many different types. Also, it has proved hard to integrate non-audio signals (video, for instance, and also audio spectra) into Max's rigid "tilde object" system. Finally, the whole issue of maintaining two separate copies of all data structures (one to edit and one to access in real time) has caused much confusion and difficulty. Pd's working prototype attempts to simplify the data structures in Max to make them more readily combined into novel user-defined data structures. Also, the relationship between the graphical process and the real-time one (which is handled in one way on the Macintosh and another way on the ISPW) is replaced by yet a third solution.
The design of real-time computer music systems has been a subject of active research since the RTSKED program [1]. By 1986 several authors were proposing formal or semi-formal real-time protocols, sometimes in the guise of complete systems for doing real-time computer music [2], [3]. The question of
making software systems which were really usable by non-computer scientists was addressed by the Max program [4]. Max was an attempt to make a screen-based patching language that could imitate the modalities of a patchable analog synthesizer. Many other graphical "patching languages" had been proposed that did not sufficiently address the realtime control aspect; and many other researchers had by then proposed much more sophisticated real-time control strategies without presenting a clear and funto-use graphical interface; Max was in essence a compromise that got part way toward both goals.
As soon as Philippe Manoury's Pluton was realized using Max (thus proving Max to be an interesting environment for real-time computer music), a stream of criticisms of Max started to appear. Max wasn't originally intended as a programming language; yet many users treated it as one. As such Max had obvious shortcomings, some of which are reported in [5]. Also, the original version of Max, being written for a Mac Plus computer, didn't address the question of computer-generated audio, remaining instead in the realm of MIDI. This was addressed in [6], but only for special hardware.
The question of how to use Max to amass and use data arose in IRCAM during the design phase of the ISPW. A new software idea, called Animal, was proposed and implemented [7]. Many ideas in Pd owe their origin to the Animal program.

Open source JDBC 3.0 type 4 driver for Microsoft SQL Server (6.5 up to 2012) and Sybase ASE. jTDS is a complete implementation of the JDBC 3.0 spec and the fastest JDBC driver for MS SQL Server. For more information see
Overview
jTDS is an open source 100% pure Java (type 4) JDBC 3.0 driver for Microsoft SQL Server (6.5, 7, 2000, 2005, 2008 and 2012) and Sybase Adaptive Server Enterprise (10, 11, 12 and 15). jTDS is based on FreeTDS and is currently the fastest production-ready JDBC driver for SQL Server and Sybase ASE. jTDS is 100% JDBC 3.0 compatible, supporting forward-only and scrollable/updateable ResultSets, concurrent (completely independent) Statements and implementing all the DatabaseMetaData and ResultSetMetaData methods. Check out the feature matrix for more details.
Quite a few of the commercial JDBC drivers out there are based on jTDS (or FreeTDS), even if they no longer acknowledge this. jTDS has been tested with virtually all JDBC-based database management tools and is the driver of choice for most of these (recommended for DbVisualizer and SQuirreL SQL, distributed with Aqua Data Studio and DataDino). jTDS is also becoming a common choice for enterprise-level applications: it passes both the J2EE 1.3 certification and Hibernate test suites, and is recommended for JBoss, Hibernate, Atlassian JIRA and Confluence and Compiere.
Getting Started
Being a type 4 driver, jTDS does not need any special installation. Just drop the jar file into your application's classpath and you're done. All you need to know is the name of the Driver and DataSource implementations and the URL format and you're all set. You can get these and a lot more information from the Frequently Asked Questions page. For features needing native libraries such as XA support or Single-Sign-On consult the specific README files.
jTDS is free software. jTDS is released under the terms of the GNU LGPL, giving you not only the posibility to debug and tweak it to your own liking but also to use it in and distribute it with your free or commercial applications.
The other "free" choices, the JDBC-ODBC bridge and Microsoft's own JDBC driver are not actually free. If you encounter an issue with any of them you won't be able to fix it yourself and response times from both Microsoft and Oracle are anything but short.
jTDS is also the most performant JDBC driver for both SQL Server and Sybase. We have an older benchmark result but we strongly encourage you to download any benchmark published by commercial JDBC driver vendors and see for yourself. Here are a couple of benchmarks you could use: JNetDirect's JDBC Performance Benchmark and i-net Software's BenchTest 2.1 for MS SQL Server.
