Free newsletter design software for linux

C2::Newsletter is a simple tool for sending newsletters to your visitors. It allows you to create multiple newsletters, so your visitors can select which topics they want to receive.
There is an admin interface to add/edit newsletters and recipients, and send in plain text or MIME-encoded. It is easy to use, but currently only in German (English will be available soon).
Enhancements:
new Features
- Verification email is now configurable (plain text only)
- Supports now the admin as recipient for verification emails
fixed Bugs:
- Admin interface allows to list the recipients of a specified newsletter
- Config page => cancel button now works
- deleting a newsletter deletes also items in c2_mail_newsletter_selections
- holds email when adding a new recipient record
- verification of new recipients now works
performance:
- function GetConfig()

The system can be used in the electronic world to keep track of your: Schematic, Printed Circuit Board, Front Plate, Programmable Logic Device numbers.
EDA index is programmed in PHP (and XHTML 1.0), using a MySQL database to store data, so its more or less OS independent, but a Linux server is recommended, since it already got most software installed as default, this configuration is also called LAMP (Linux Apache MySQL PHP)
Its also recommended that a local intranet server is used, since the system dont got a user login, so all data can be viewed without a password, but when you need to add or edit data a password is required. At first this approach might seem wierd, but its designed to allow quick lookups. Example:
You are sitting with a broken pcb with a number on it, and need to find the schematic (so you can repair it) on the computer or in the printed project (schematic) archive. EDA Index allow an quick lookup in the database, without you needing to login, so you get the job done faster.
As far as I know, there are no commercial (or free) program available that can do what EDA Index can, some companies may have created their own software, but how do that help you.
I have worked in an electronic department that had a self made application, but it lagged features like search.
This program is very usefull, if you are using numbers when:
Drawing electronic Schematics and PCBs using a CAD program like: Eagle, gEDA, Protel, Orcad, etc.
Creating Front Plate layouts in: GIMP, Coral Draw, Photoshop, AutoCAD, etc.
Programming Programmable Logic Devices like: PLD, EPLD, CPLD, PIC, APIC, PEEL, PAL, GAL, FPGA, Intel 80XX, Motorola 68XX, etc. Writing the code in: VHDL, Assambler, JEDEC, etc.
Enhancements:
- Included the bugfix to RC2.
- Updated online documentation.
- Updated INSTALL file.

DB Designer Fork is a fork of the fabFORCE DBDesigner 4. DBDesigner is a visual database design system that integrates entity relationship design and database creation.

The project generates SQL scripts for Oracle, SQL Server, MySQL, and FireBird.

Electronics Optimizer project is an electronics design tool for advanced optimization and design of electronic circuits - with Monte Carlo, Optimizer and Worst Case Analysis.

Electronics Optimizer helps you to quickly design a circuit (choosen from a standard library of circuits) to match your specified design parameters without drawing a schematic. Moreover Electronics Optimizer has a calculator for first-cut estimates for designers.

Bowzilla is a mini Game for 2 players. Leaned against the old QBasic Gorilla, you must fire at your opponent in real-time.

Particularly the realistic blood is to be considered with the lightning strike. You have to find a whole in the target range. However, you should not expect to much from it.

Java::Import::Design is the design of the Java::Import Module.

MOTIVATIONS

The original motivation for writing this module came out of a project I was working on during my previous employment. We had built a system in which a major part was implimented using EJBs on a J2EE server. In addition, we had a large component of the system, that already existed, and was written in Perl. We did not want to scrap our Perl work but it was becoming more tedious to maintain two implimentations as more and more things were being added to the system.

So, we decided that the major pieces of business logic would reside on the J2EE server and the Perl would be modified to make calls to the server. After some time and experimentation we began to realize that the memory footprint as well as the amount of time needed to make calls to the server using existing Perl to Java integration sulutions were just not acceptable. We therefore set out to find some other way. We tried all sorts of things but in the end we couldnt find anything that met our requirements and therefore decided to keep the origional system of doing things.

While at that job we never did find a suitable way to integrate our two systems. However, the problem still haunted me. It wasnt until the end of my career at that company that I saw an announcement for Googles first Summer of Code. It just so happened that as Google was announcing their brand new program that I had begun to play with the GNU GCJ suite of Java tools and came up with the idea of taking advantage of their ability to natively compile Java code for use with Perl. This may not have been a new idea but I couldnt find anything that would help me so I decided to write and submit a proposal to Google. Well, I was accepted and you now have Java::Import.

When I began to work on this project I started by creating my own namespace instead of stepping on the toes of the other existing Java/Perl integration project, Inline::Java. I did this primarily because I wanted a clean slate on which I could fully explore the nuances of GCJ, in particular its CNI interface. As I worked my module started to evolve into its own beast and at that point it seemed locigal to keep my own namespace. It is not my intention to replace Inline::Java and I still think that in te future much of the work I have done can be used by Inline::Java as an option to use GCJ specific functionality.

GSpeakers is a loudspeaker design program designed for the Gnome desktop.

GSpeakers is built using the Gtkmm libraries (C++ wrapper for the Gtk+ libraries http://gtkmm.sf.net).

The reason I started to work on this program was that I could not find any other Gtk/Gnome based loudspeaker design program. The question I had to ask myself was: How can I make it easier to design loudspeakers?

GSpeakers aims to be easy to use but still powerful enough ful the experienced loudspeaker designer.
