Free functional software for linux

Erika Educational is a a fully fledged and fully functional real-time operating system (RTOS) for embedded devices.

Erika Educational is a reduced GPL-licensed release of Erika Enterprise: ideal for educational purposes, free software, and available for download at no cost.

Erika Educational should not be seen as a reduced set of Erika Enterprise. Therefore, please do not consider Erika Educational for evaluating the characteristics and performance of Erika Enterprise. While the two originated from the same source code base, Erika Enterprise has been completely redesigned and rewritten to meet industrial needs, whereas Erika Educational have been adapted to 8 bit educational architectures.

Impressions based on Erika Educational should not be applied to Erika Enterprise, as their feature sets are different, and they are, in practice, two different projects, with two different code bases.

Netautor Professional webapplication is an Application Server with integrated Development Environment.
The provided framework assists the developer with the programming of databased Web Applications.
The excellence of Netautor Professional is it`s wide functional range and the for this reason high flexibility. All demands on the Intra- or Intranet are realizable.
Netautor Professional is based on the Scripting Language PHP and can be used on numerous common platforms. It is licensed under the GPL.
Enhancements:
- Check user password via LDAP server
- "Pretty printing" on the source code continues ...
- Some minor fixes
- Define a target charset in functions like NPF_GETVAL.

FunkLoad project is a functional and load web tester, written in Python, whose main use cases are:
- Functional testing of web projects, and thus regression testing as well.
- Performance testing: by loading the web application and monitoring your servers it helps you to pinpoint bottlenecks, giving a detailed report of performance measurement.
- Load testing tool to expose bugs that do not surface in cursory testing, like volume testing or longevity testing.
- Stress testing tool to overwhelm the web application resources and test the application recoverability.
- Writing web agents by scripting any web repetitive task, like checking if a site is alive.
Main features:
- Functional test are pure Python scripts using the pyUnit framework like normal unit test. Python enable complex scenarios to handle real world applications.
- Truly emulates a web browser (single-threaded) using Richard Jones webunit:
- basic authentication support
- cookies support
- fetching css, javascript and images
- emulating a browser cache
- file upload and multipart/form-data submission
- https support
- Advanced test runner with many command-line options:
- set the target server url
- display the fetched page in real time in your browser
- debug mode
- green/red color mode
- Turn a functional test into a load test: just by invoking the bench runner you can identify scalability and performance problems.
- Detailed bench reports in ReST or HTML (and PDF via ps2pdf) containing:
- bench configuration
- tests, pages, requests stats and charts.
- 5 slowest requests
- servers cpu usage, load average, memory/swap usage and network traffic charts.
- http error summary list
- Easy test customization using a configuration file or command line options.
- Easy test creation using TestMaker / maxq recorder, so you can use your web browser and produce a FunkLoad test automatically.
- Provides web assertion helpers.
- Provides a funkload.CPSTestCase to ease Zope and Nuxeo CPS testing.
- Easy to install and use, see examples in the demo folder.
Enhancements:
- This release fixes some HTTP encoding and reporting bugs, it also brings support for Python 2.5.

Caml is a general-purpose programming language, designed with program safety and reliability in mind. It is very expressive, yet easy to learn and use. Caml supports functional, imperative, and object-oriented programming styles.

It has been developed and distributed by INRIA, Frances national research institute for computer science, since 1985.

The Objective Caml system is the main implementation of the Caml language. It features a powerful module system and a full-fledged object-oriented layer.

It comes with a native-code compiler that supports numerous architectures, for high performance; a bytecode compiler, for increased portability; and an interactive loop, for experimentation and rapid development.

CTBClient is a mobile client for the CTB. The main objective of CTBClient is to allow registering expenses and other financial events in the road, and later uploading them to the mother system.
It puts in use a set of exciting technologies: Bluetooth, Python SQL DBI, serialization (marshaling) of objects, GTK+, Python for Series 60 Nokia cell phones (known as S60), perhaps PyObjc in future Mac OS X versions etc. CTBClient is also meant to be a guinea pig for portable Python development.
CTBClient is a project sponsored by INdT - Instituto Nokia de Tecnologia (Nokia Institute of Technology), where I work and have the environment and time to make such experiments.
Functional clients are:
- GTK+ Linux/local (no Bluetooth, for quick tests);
- GTK+ Linux Bluetooth
- Symbian/S60 cell phone
- GTK+/Hildon Linux (Maemo platform, like Nokia 770 tablets)
Functional servers:
- Linux/local (for testing)
- Linux/Bluetooth

Brinance is a commandline financial planning and tracking program, hoping to be a functional replacement for something like GnuCash for those who prefer the command line.
Brinance does not have all the features of GnuCash, but it does have a few beyond being a checkbook register: scheduling transactions in the future, multiple accounts, recurring transactions, and a Perl module to allow just about any interface to the program to be easily written.
Enhancements:
- Recurring transactions were added, using a cron-like format.
- The file format was changed.
- Transfers were added.
