Free high quality design software for linux

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.

Adaptive Quality of Service Architecture (AQuoSA) is an open architecture for the provisioning of adaptive Quality of Service functionality into the Linux kernel. The project features a flexible, portable, lightweight and open architecture for supporting soft real-time applications with facilities related to timing guarantees and QoS, on the top of a general-purpose operating system as Linux.
At the core of the architecture there is an adaptive resource reservation layer that is capable of dynamically adapting the CPU allocation for QoS aware applications based on their run-time requirements.
Timing guarantees are provided through an in-kernel reservation based process scheduler, whose services are exposed to applications through a well-designed API.
A supervisor performs admission control, so that admitting into the system new applications with timing guarantees does not affect the timing guarantees of already admitted applications. Also, it takes care of guaranteeing appropriate security policies in the assignment of timing guarantees to users and user groups, as configured by the system administrator.
A feedback-based QoS control layer may be optionally used by applications who want to keep their timing guarantees by using a CPU allocation that is continuously adapted according to their actual needs. This leaverages the programmer, within certain limits, to hard-code any particular reservation amount within the application, because the best allocation is found out automatically at run-time. Also, this enhances the possibilities for the system to host additional QoS controlled applications. The available control algorithms are well founded on formal scheduling models and control theoretical results.
Enhancements:
- This release introduces a couple of flags useful when creating servers. If QOS_F_PERSISTENT is enabled, a server is allowed to exist beyond detach of the last task. If QOS_F_SOFT is enabled, a server tasks are scheduled by the Linux default scheduler/policy, when outside of the server reservation.
- Also, various stability issues in destroying servers have been fixed, also thanks to a new release of the generic scheduler patch for the Linux kernel (gs-2.2).

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.

libAfterImage is a small, fast, and powerful library for high-quality image manipulation.
libAfterImage is a generic image manipulation library. It was initially implemented to address AfterStep Window Managers needs for image handling, but it evolved into extremely powerfull and flexible software, suitable for virtually any project that has needs for loading, manipulating, displaying images, as well as writing images in files.
Most of the popular image formats are supported using standard libraries, with XCF, XPM, PPM/PNM, BMP, ICO, TGA and GIF being supported internally.
PNG, JPEG and TIFF formats are supported via standard libraries.
For convinience, source for libJPEG and libPNG is supplied with libAfterImage.
Powerfull text rendering capabilities included, providing support for TrueType fonts using FreeType library, and antialiasing of standard fonts from X window system.
Primary design goals of libAfterImage are memory efficiency and superior image quality.
Extensive documentation, examples, and XML image scripting tool ascompose, are included with the library.
libAfterImage allows output of the image on any of the X11 display, MS Windows DIB, or standard output, which is suitable for web servers.

Java Lemonade Stand is a lemonade stand game. To play the game, click on the link below.

You are the sole proprietor of a lemonade stand in your front yard. Your parents were kind enough to knock together a booth and provide some initial capital and supplies.

You have three months to make as much money as possible. Placing money in the bank is a good idea. You earn interest.

The left side of the display contains four tabs (Prepare for Sale, Finances, Inventory, and Advertising) for managing your advertising and assets. The left side displays sales results and weather forecasts. Check the weather forecast then decide how much advertising to purchase, how many cups to make, and how much to charge. Press the Sell Lemonade button to see how you fared.

Prepare for Sale

Here you decide what quality of lemonade mix to use (Generic, Name Brand, or Premium), how many cups of lemonade to prepare, and how much to charge for each cup. Using a higher quality of lemonade will positively impact the price customers will pay and the number of cups they will purchase.

Finances

Your money is divided into working cash and a savings account. Purchases for supplies and advertising are deducted from your working cash. Profits from your lemonade sales will be added to your working cash. You can transfer money between your working cash and savings account. You will receive interest on your savings account at the end of each month. The interest is based on your average daily balance.

Inventory

Your inventory consists of lemonade mix and cups. Buying in larger quantities is more cost-effective. You can only make and sell as much lemonade as you have mix and cups. Lemonade mix comes in different levels of quality: Generic, Name Brand, and Premium. Higher quality lemonade costs more.

Advertising

Advertising helps to bring more customers to your stand. Notice that some types of advertising last multiple days while others only last for a day. Homemade signs last a variable period of time.

Weather

Weather has a significant impact on the number of customers that come to your stand and the amount that they will pay for your lemonade. You will receive a forecast for the next days weather each day. This forecast is somewhat accurate but not 100% reliable. The eight types of weather are listed below.

Sunny and Scorching: Ideal conditions.
Sunny and Hot
Sunny and Warm
Sunny
Party Sunny
Overcast
Rain
Thunderstorms: Worst conditions.

Sales Results

Here you will see the weather for the day, the number of customers who visited your stand, the number of cups you sold, and your gross and net profit. You will also learn about any random events that might impact your business.
