Free solid of rotation software for linux

There is quite a bit of history on this item. One of the assignments in a computer graphics course at the University of Victoria was to rotate a number of Bezier curves around an axis and display the result in 3D using a single light source.

This was on Sun Sparcs using X. Since then the program has mutated to match my platform preference at a given time (DOS, Windows, Linux).

The latest mutation has been to SDL/OpenGL and the result runs happily on Linux and Windows. Screenshot junkies might find the following of interest:

SolidState is a web-based Customer Management and Billing solution designed for Web Hosting companies. SolidState project is developed in PHP, and uses MySQL as the backend database. It is licensed under the GPL, meaning the source code is available for free and you are encouraged to modify it, improve it, secure it, and submit your changes back to the project.
Some things you can do with Solid-State include:
- Track active, pending, and inactive accounts
- Create and track invoices that can be printed or emailed to your customers
- Specify your own recurring web hosting and domain registration services
- Setup one-time purchases, such as add-on services or special fees.
Register domains through a reseller API, if supported (at this time only Directi/Reseller Club is)
SolidState is a young project, started by John Diamond in November 2005, and sponsored by Solid Internet Systems, Inc. The current and first public release is v0.2. The goal of the project is for version 1.0 to be a complete open source alternative to the existing commercial solutions for web host customer management.
Obviously these products are much more feature rich than the current state of the project, but it is hoped that many will contribute their skills to this fledgling application, and produce not just a more affordable, but a more usefull, more secure, and more intuitive solution for the entire Web Hosting industry.

mod_log_rotate is an automatic in-process rotation of transfer log. Replaces rotatelogs.

If you host a lot of virtual servers on a single Apache box and use the supplied rotatelogs program to rotate the logs you’ll notice that your process table is cluttered up with an instance of rotatelogs for each virtual server.

With mod_log_rotate the log rotation is handled by the server process so you save a bunch of processes and file descriptors.

Installation:

Install mod_log_rotate using apxs as follows:

$ apxs -i -a -c mod_log_rotate.c

Configure:

Load and enable mod_log_rotate by adding two lines to your httpd.conf. For Apache 1.3 use

LoadModule log_rotate_module libexec/mod_log_rotate.so
RotateLogs On

and for Apache 2 use

LoadModule log_rotate_module modules/mod_log_rotate.so
RotateLogs On

The LoadModule line may have already been added if you used the apxs -a (activate) option when compiling the module.

If you are using the Apache 1.3 version of the module you will also have to replace any CustomLog, TransferLog, LogFormat and CookieLog directives with the corresponding RotateXXX version. For example

TransferLog logs/access_log

would become

RotateTransferLog logs/access_log

You may need to review the permissions on your log directories. Normally Apache creates log files while it’s running as root and then becomes nobody (or whatever user you’re running it as) before it starts serving pages. In order to be able to create new log files during rotation the permissions on any log directories need to allow writes by the web server user.

The remainder of the directives provided by mod_log_rotate control the interval and timing of log rotation. The configuration directives may be used globally or per virtual server.

Solid PBX project is a multi-platform Soft Switch Class 5 software targeted for home, corporate, and operator level markets.
GETTING STARTED
First, be sure youve got supported hardware (but note that you dont need ANY special hardware, not even a soundcard) to install and run Solid PBX.
Supported telephony hardware includes:
- All Wildcard (tm) products from Digium (www.digium.com)
- QuickNet Internet PhoneJack and LineJack (http://www.quicknet.net)
- any full duplex sound card supported by ALSA or OSS
- any ISDN card supported by mISDN on Linux (BRI)
- The Xorcom AstriBank channel bank
- VoiceTronix OpenLine products
The are several drivers for ISDN BRI cards available from third party sources. Check the voip-info.org wiki for more information on chan_capi and zaphfc.
Enhancements:
- Sound files and music on hold files supplied for use with Solid PBX have been replaced with new versions, and are available in two languages (English and French) and in five formats (WAV (uncompressed), mu-Law, a-Law, GSM, and G.729).
- In addition, the music on hold files provided by FreePlay Music are now available in the same five formats, but no longer available in MP3 format.

rotatezlogs allows you to let Zope rotate your log files with rotatezlogs.
This product provides two additional logger handlers to the standard ones (see the doc in zope.conf) that rotate the log files.
It is not always possible to rotate Zope logs using system wide services. This utility enables to rotate automatically Zope logs (with or without zipping) using the features of the "logging" standard module.
Dont look for new objects in the ZMI factory. All is configured in zope.conf.
Note that the log rotation rules is based on the actual size of a log file, and not on time periods (cron like).
Enhancements:
- Unified handlers (simpler to document and configure)
- Added gzip and bzip2 compression modes.

SDXF is a Python library to generate DXF files. DXF is an abbreviation of Data Exchange File, a vector graphics file format.
It is supported by virtually all CAD products (such as AutoCAD, Blender, 3Dstudio, Maya,Vectorworks...) and vector drawing programs (such as Illustrator, Flash, ...).
This Python library can generate complex CAD drawings (dxf format) with all kind of entities (such as 3DFace, Arc, Insert, Circle, Line, Mtext, Point, Polyline, Rectangle (can be filled), Solid & Text).
They can be structured with Layers, Blocks, Linetypes, Text styles and Views. See the manual for more info.
Main features:
SDXF supports the most of DXF drawing objects:
- 3DFace
- Arc
- Insert (block)
- Circle
- Line
- Mtext (as a series of texts)
- Point
- Polyline (as a series of lines)
- Rectangle (can be filled)
- Solid
- Text
SDXF supports the most of DXF tables:
- Blocks
- Layers
- Linetypes
- Text styles
- Views
Enhancements:
- Blocks can now be inserted with rotation, and a typo in the demo function has been fixed.
