The "Open Device Monitoring and Tracking Protocol", otherwise known as OpenDMTP, is a protocol and framework that allows bi-directional data communications between servers and devices (clients) over the Internet and similar networks.
OpenDMTP is a highly configurable and extensible protocol for communicating with mobile devices.
OpenDMTP is particularly geared towards Location-based information (LBS) such as GPS, as well as temperature and other data collected in remote-monitoring devices. OpenDMTP is small, and is especially suited for micro-devices such as PDAs, mobile phones, and custom OEM devices.
We saw a need for a communications protocol that allowed high-latency, low-bandwidth (HL/LB) devices to transmit location data to monitoring-systems. Because these devices often have limited network connectivity, the protocol needed to be small and efficient. Example devices include mobile phones, PDAs, OEM micro-devices (alarm systems, temperature monitors, etc.), and more.
There are many mobile GPS tracking devices on the market today with their own closed proprietary protocols. Searching the web for open protocols revealed only a few available for transferring data (including GPS information) between devices. However these solutions are generally designed for non-mobile applications and/or lack some of the low-bandwidth, configurable, and extensible features that mobile applications require.
Main features:
- Small Footprint: Mobile devices typically have limited resources on which to run client code (ie. memory, processor speed). An open protocol designed with this in mind should be optimized to allow efficient implementation and should easily support devices such as PDAs, mobile phones, GPS monitoring devices, and other OEM micro-devices.
- Network Efficient: Mobile devices typically have limited network connectivity, and in some cases data communication can be quite expensive (e.g. satellite). Because of this the protocol needs to be efficient in its dialog between the client and server. The communication needs to be optimized such that the necessary information can be conveyed with a minimum number of bytes in the least amount of time.
- Bi-directional: Some devices can support two-way communication (ie. GPRS, or other socket based connections), while others may only support one-way communication (ie. some satellite communication systems). With this in mind, a protocol should be designed to support both duplex (two-way) and simplex (one-way) communication.
- Transport Media: Differrent mobile applications will have their own unique way of communicating data back to the server. Some may use GPRS, or socket based communication, others may use satellite communication, while still others may use other forms of wireless communication, such as BlueTooth. The design of the protocol should be able to encompass all such transport media types, regardless of the type of transport in use.
- Flexible Data Encoding: Most types of transport media allow for the transmission of binary encoded data. However, there may be some forms of media for which an ASCII encoded data packet is much better suited. A protocol designed with this in mind should be able to support both types of data encoding.
- Configurable Messages: Due to the broad range of data types used in mobile applications, the protocol should be flexible enough to define standard messages, yet still allow custom messages within the framework.
- Extensible: Not every mobile application is the same. Some require special handling and may have various types of inputs and outputs. A protocol designed for mobile applications should insure that the framework can be easily extended to incapsulate the specific needs of the device.
- Industry Compatibility: Having an open protocol insures better compatibility between different client devices and service providers.
- Reference Implementation: Having a reference implementation that showcases the major features of the protocol provides an easy starting point on which developers can add their own features and platform specific implementation without having to worry about how data gets from the client to the server.
OpenDMTP was specifically designed to suit all these needs, especially "Small Footprint" and "Network Efficiency". The typical data plan for GPRS communication, for instance, is usually 1Mb per month. OpenDMTP was designed to optimize packet encoding to allow the collection of GPS information packets once every 3 minutes, 24 hours a day, 30 days a month, and still stay under the 1Mb data plan limit.
While XML is very extensible, it fails the "Small Footprint" and "Network Efficiency" requirements. Thus, it was discounted as a viable protocol solution. Many mobile devices do not have the resources necessary to be able to provide full XML parsing functionality. And an XML packet may need to be several hundred bytes in length just to send a few bytes of actual data. This alone would make the solution cost prohibitive for high-cost transport media such as satellite.
OpenDMTP also includes a full-featured commercial quality reference implementation to jump-start development.
Enhancements:
- NEW: Minor optimizations made to message logging.
- FIX: Log file now properly displays account/device on client connection.

Zen Cart truly is the art of e-commerce; a free, user-friendly, open source shopping cart system. Zen Cart software is being developed by group of like-minded shop owners, programmers, designers, and consultants that think e-commerce could be and should be done differently.
Some "solutions" seem to be complicated programming exercises instead of responding to users needs, Zen Cart puts the merchants and shoppers requirements first. Similarly, other programs are nearly impossible to install and use without an IT degree, Zen Cart can be installed and set-up by anyone with the most basic computer skills. Others are so expensive ... not Zen Cart, its FREE!
Zen Cart will deliver the ultimate online shopping experience to your customers. Navigating through your merchandise offerings is a breeze with Zen Cart, the program provides several "Spotlight" lists in addition to the traditional category to product links. Once a product is added to the shopping cart, secure checkout is a simple 3-step process.
After providing the billing information, your customer chooses the shipping method. (multiple shipping methods including real-time internet shipping quotes are built-in) Next, a payment type is chosen from one of the popular payment modules. (PayPal and AuthorizeNet are just 2 of the included modules) Last, the customer reviews the order, shipping and payment choices, and confirms the order.
You are immediately notified of the order and your customer automatically receives an e-mail confirmation.
Zen Cart addresses many of the goals we set:
- make the program easy to set up
- make it easy to customize
- automate tasks, such as order confirmation
- make navigation simple
- built in promotions; discount coupons, gift certificates, newsletters and product notification
- offer single item specials and storewide discounts (group discounts and quantity discounts - Coming in future editions)
- built in Search Engine Optimization tools
- password protect the Administration Tool (administration "levels" - Coming in future editions)
- support multiple languages, currencies and tax structures
- In short, Zen Cart is shopping cart software the way it should have been all along.
Zen Cart gives web designers a robust and customizable electronic storefront thats easy to keep up-to-date with new features.
It provides usable, intuitive and unobtrusive purchase flows right out of the box based on proven industry best-practices - there are no major revisions required to get things right for your clients!
One of the secrets behind its power lies in our robust template system that "abstracts" the look-and-feel from the code and logic behind Zen Cart. This enables you to give clients a truly custom solution that integrates quickly and perfectly with their existing marketing websites.
Developers are able to deploy cutting edge solutions based on Zen Carts modern standards and technologies. Combining PHP server-side technology with the ability to choose from multiple databases on the back end (coming in future editions, thanks to ADOdb), results in flexible software that you can customize and modify to suit your needs. Minimum/suggested server requirements: PHP 4.1.x or higher (PHP 4.3.3+ for optimal performance), Apache 1.3.x and MySQL 3.2x.x or higher.
Enhancements:
- Two vulnerabilities related to cross site scripting (XSS) have been fixed.
- Officially certified for Paypal Express Checkout (only for North American Paypal accounts as of 20070101).
- Also includes several minor improvements and bugfixes.

iptables accounting monster (iam) is a traffic reporting tool for iptables. Currently it can generate daily reports in plain text and HTML format. It can also create summaries (month or year) of these daily reports.

While looking for a traffic reporting tool, I didnt find something that i looked for. So I started to write iam, which:

is free software
works with Linux 2.4 iptables
is written in Python, a readable language (i.e. not perl, awk or shell script)
is secure (i.e. only be root where you need to be root)
doesnt depend on a specific web server or database server
can generate reports for routers or servers
can generate reports in plain text or HTML format
can calculate costs for traffic (currently only price per MB, but bulk discounts should be included soon)
