Car Dealer Website allows you to get your car dealership inventory on the Web. Car Dealer Website projects easy-to-use system features full searching capability by make/model, price range, and year range.
Each listing has a contact form where buyers can easily make contact from your site on a particular vehicle.
You can upload as many images as needed per listing and setup as many makes and models as needed for your dealership. It is fully template driven, and is easy to customize.
Installation:
-copy all files to your web host
-use phpmyadmin or your mysql interface to run site.sql against your database.
-chmod 777 upload/ and upload/tmp/
-open site.xml and edit the database section with your database details.
-go to admin/ and login with username of admin with a password of test.
-be sure to change the passwords for the admin and regular user.
Setup the site.xml file with your database settings as follows.
< database type="mysql" >
< server >database server address< /server >
< login >database login< /login >
< password >database password< /password >
< default >mysql database name< /default >
< /database >
Add this to your htaccess file to prevent viewing of the xml config file.
< Files ~ ".xml" >
Order allow,deny

Enhancements:
- Some of the lines of code within the library files were fixed up to improve the speed of the system.

Yoxel Systems is a software product management and customer feedback management solution. Yoxel Systems is a connected system to track product requirements, manage product life cycles, provide online customer support, and accumulate support knowledge.

Yoxel Systems is more than yet another bug tracker, helpdesk or project organizer. It bridges request tracking and project management by providing a flow manager that walks your team from request prioritization and project planning through project implementation to project completion.

Unlike web based portals from SalesForce.Com or SugarCRM Yoxel Systems is tailored specifically for software development companies.

WHY YOXEL SW?

A role based, easy to use and very flexible request tracking system with customizable workflow, powerful filtering and advanced reporting capabilities.

Product management capabilities and agile methods of development on top of your existing Bugzilla/Mantis/GNATS/...

Automated process for product requirements management and product development planning/tracking.

Efficient collaboration between R&D, marketing and customer support teams to increase relevancy and value of your product releases.

Improved customer support that gives you fast and more accurate customer feedback on product requests and priorities.

WHY YOXEL IT?

The work of IT departments is not just about supporting users and resolving various network issues, it is also about implementing complex projects concerning. infrastructure and efficiency of your systems and business:

YOXEL IT is the solution for your IT department:

Ticket Tracking System is flexible and powerful, packed with features you expect from professional IT helpdesks.

Yoxel IT Project Management System extends TTS allowing your IT specialists to collaborate, plan and track complex IT projects.

Crashtest simulates car crashes. Crashtest is an educational tool that can be used to acquire much insight into this complex process.

The user can learn about the relation between speed and stopping distance. Also, many physical properties can be studied.

Crashtest is developed by Bram Stolk, SARA, and was commissioned by NWO for the Weten Week 2006 in the Netherlands.

Xitnalta Content Management System (xcms) provides a virtual filesystem library to deal with content from different sources (a real filesystem, a database, etc.) and in different formats.

Xitnalta Content Management Systems goal is to provide yet another way to access and manage data both locally and over the Internet.

CarWorld is a small driving simulator/demo I use to test various things of interest. It was mostly developed when I was a student. Car World is released with the full source code under the GNU General Public License.

The rendering

The two top pictures represent an slightly older version (v0.072) but graphically similar of CarWorld as it was presented for my project. v0.072 includes an OpenGL based renderer allowing
file input and displaying of texture mapped models with interpolated surface normals, real time projected shadows (as seen in the dino lights example).
background object
on screen command line to modify visual and simulation parameters

The mechanics

based on classical mechanics
uses standard metrics (Newtons, meters, seconds...)
there are no constraints on the environment surface
variable length time increments and variable increment number means "CarWorld time" is not dependent on frame rate.
adjustable simulation specs include: metrics, mass, moment of inertia around rotation axis, suspension pre load, compression damping, rebound damping, engine torque output, air friction, surface friction.

JACK Meterbridge is a meterbridge for the UNIX based JACK audio system.

It supports a number of different types of meter, rendered using the SDL library and user-editable pixmaps.

Supported meters

PPM - Peak Program level Meters

Approximatly conforming to BS 6840-10. These meters are designed to indicate peak amplitude, as opposed to VU meters which are designed to indicate volume.

The scale is correct according to the standard, 4 equates to 0dB, 1 to -12, 7 to +12, and it is linear with decibels.

Ive never used a real PPM meter, so I dont know if it reacts correctly. Feedback welcome.

VU - Volume Unit meters

Conforming to BS 6840-17:1991. Real meter is larger.

These meters are designed to measure the "volume" of an audio signal, it is not as relevant to digital systems as PPM meters, but is useful if you are interfacing to analogue tape, FM broadcast equipment or want a general idea of the signal volume.

The -r flag (set reference level) is usful with these meters as it will allow you to calibrate to your DA converters. The meter is pre-adjusted so that it should allign correctly calibrated DA converters with analogue systems. If you wish to run with 0dBFS = 0dBu then use "-r 20"

DPM - Digital Peak Meter

Conforming to IEC 268-18:1995 (peak indiciator decay may not be correct).

These are meters as typically seen on digital consoles, HD recorders etc.

There are the most efficient in screen realestate and CPU use but look a bit boring.

JF - "Jellyfish" Meter (aka. Goniometer)

A jellyfish meter is a stereo scope display, it can be used to spot phase and mono compatibility problems.

Some charateristic problems can be seen, eg. a signal with a stronger left channel is seen as a shape sloping to the left [], more right slopes to the right [/], and dead mono is a vertical line [|].

The meter below the scope display indicates the degree of stereo correlation between the channels, a value of +1 means that it is perfectly mono compatible, and -1 and that the channels are in anti-phase (so they will cancel out if mixed).

If someone has better examples, please mail them to me, there are probably tutorials online.

SCO - Scope

A rendering of an oscilloscope display.

It has a basic trigger function, but there is no timebase control. It renders one pixel per sample, so it will probably be next to useless at 96KHz
