Free sample newsletter software for linux

Oxylus Newsletters System is a complex newsletter system. It allows you to manage multiple groups.
You can import and export users, and public subscription is allowed. Oxylus Newsletters System project allows linux users to schedule newsletters for a specific date using a crontab job.
For each sent newsletter, you can see its history and whether it was successfully sent.
Enhancements:
- This version is fully compatible with PHP5.
- The mails are sent just once to all the users.
- The SQL error which occurred when new groups are created was fixed.
- Various framework bugfixes were made.

Sample Inventory Program provides a laboratory inventory management system (LIMS) for Zope.
Many integration tests exist for various aspects of the SIP application, ranging from command line importing of samples and project configuration to CSV Web-based importing of sample modifications.
Main features:
- Cross platform using the Zope 3 appliation server and Python language. Contains over 200 unit and integrations tests.
- Command line import functionality (import application configuration, projects, samples, aliquots and container heirarchies)
- Cross project searches based on Subject Ids, Other Ids, Additional Sample Data, and Sample Types. Uses REPORT Permission.
- Search Form Screenshot
- Project level permissions. Users can be enabled/disabled by removing User Permission in the Applicaiton root. Lab Technician Permission allows users to put contents into a shipment and add/modify Samples. Project Manager permission allows project configuration as well as administering Users for specified projects.
- User and Permission Screenshot
- 100% Web based interface (IE, Mozilla, Safari tested). QT based client in development.
- Projects Overview Screenshot
- Ability to Split Aliquots into smaller units and put them into separate physical containers.
- Ability to Derive Aliquots into other Sample Types. Derived Samples/Aliquots links to their origin sample.
- Locations/Containers are heirarchical and can be restricted to a Project
- Shipments act as virtual containers where Lab Technicans can split aliquots into. AlsocShipments contain Contact Info, Shipping Info and Funding Info. While the Shipment Status will control the status of the Shipment moving from: Incomplete, In-Transit, and finally Received based on date fields being filled out.
- Shipment Screenshot
- Understandable relational model that enables simple reporting to be easily constructed by third party tools such as Jasper Reports
- Batch editing available using CSV files. All changes are transactional. You can easily import hundreds of samples into multiple projects by using CSV files and importing them through the web interface. You can change locations of aliquots by using the CSV import functionality. Any functionality that can be done in the web interface is complimented by CSV functionality.
- Project Search Results Screenshot
- Ability to administer Sample Type, Container Type, Locations and Unit of Measure at the application level to enforce standards across all Projects. Requires Application Manager permission.
- Ability to assign Sample Type, Locations, Technicans in a Project by Project basis.
- Project Administration Screenshot
- Advance Attribute Capture forms enable Project Administrators to specify what attributes for their Sample Types need to be captured for their project. Now non-technical users can ensure that Lab Technicans capture any attribute for any Sample Type. Attributes are limited to: DateTime, Boolean, Float, Integer, String and Text fields. Default Values can be assigned.
- Sample Type Attributes Screenshot
- Finally Sample Type Attributes can have validation scripted on a field by field basis. By using the TALES Validation functionality for Sample Type Attribute Fields. Examples of TALES validation:
- python: value < 100 # value of the field is less than 100
- python: value < datetime.date(2006, 10, 31)
- # value of the field is less than 10/31/2006
- Edit Comments will require a comment to be added to any field that is edited. These are used in conjunction with RDBMS triggers to keep a audit log to ensure that all changes to all inventory can be tracked.

Cheesetracker is a portable Impulse Tracker clone. CheeseTracker supports all Impulse Tracker features except a few.
For now the main goal is to remain at IT Feature set level, but very soon we might be adding new features to it.
Main features:
- Modular source code
- Per-track lowpass filter (cutoff/resonance), with greater range than IT.
- Per-instrument modular effect core (own effects/and ladspa) (WIP!)
- Wave export (dump your song to wavs and post process) (WIP!)
- Super-Clean mixing using the CheeseMusic lib.
- All IT editing shortcuts (or most of them)
- Very cool sample editor
And Lacks:
- MIDI Out - (go check ShakeTracker if you want this)
- Sample Sustain Loops (maybe someday)

SDL_net library is a small sample cross-platform networking library, with a sample chat client and server application. The chat client uses the GUIlib GUI framework library.

Simple DirectMedia Layer is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. It is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power."

Simple DirectMedia Layer supports Linux, Windows, BeOS, MacOS Classic, MacOS X, FreeBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. There is also code, but no official support, for Windows CE, AmigaOS, Dreamcast, Atari, NetBSD, AIX, OSF/Tru64, RISC OS, and SymbianOS.

SDL is written in C, but works with C++ natively, and has bindings to several other languages, including Ada, Eiffel, Java, Lua, ML, Perl, PHP, Pike, Python, and Ruby.

Requirements:

• Java Runtime Environment (JRE) version of 1.4 or later
• 5 MB disk space

The Net::IMAP::Simple library provides a simple-to-use, yet feature-rich Perl to IMAP API.
Enhancements:
- Fixed error in sample code within the POD documentation identified by Matthew S. Hallacy

CheeseTracker is a software sampler and step-based sequencer. It allows a musician to turn single-note samples into instruments capable of covering three or four octaves (by playing the samples at different speeds, resulting in different pitches). In addition, it is possible to take a collection of samples that are recorded at different octaves, and combine them into a single "instrument," allowing for even more octaves without sampling artifacts.
Using the Pattern Editor, it is possible to compose songs with these instruments that the computer plays automatically. The Pattern Editor allows the user to arrange samples in several independant channels, so that many samples can play simultaneously. These songs, and the samples which comprise their instruments, can be saved together in one-file archives called modules.
CheeseTracker imposes no limits on the length of the samples used. As a result, it can be used as a mixer as well as a sampler/sequencer. Effects such as reverb can be applied to each sample individually, eliminating the need for expensive pedals.
It is distributed under the terms of the GNU General Public License.
CheeseTracker is modeled after a DOS-based freeware program called Impulse Tracker (which has been abandonware since the late 1990s). It is mostly compatible with Impulse Tracker, being able to load Impulse Tracker files.
Main features:
- Unlimited sample size
- Keymaps: Build instruments that use a range of samples, just like a hardware sampler.
- LADSPA sound effect filters with near-analog quality
- Built-in effect filters:
- Amplifier
- Reverb
- Stereo Chorus
- Echo
- Equalizers: 6, 10, 21, and 31 bands
- Distortion
- Pitch Shift
- Effect filters can be combined.
- Up to 64 simultaneous voices
- Volume, pan, and pitch envelopes with sustain loop
- Built-in sample editor
- Sample loops with forward and ping-pong modes
- Compatible with JACK, ALSA, and OSS audio architectures
- Most functions are accessible from the keyboard
- Plays samples at different pitches to create notes
- Simulated live musical keyboard (using a QWERTY keyboard) can play alongside programmed songs
