Tales of Middle Earth (ToME) is a fantasy adventure game, based on the works of J.R.R. Tolkien. It is a game that emphasizes intricate, challenging, and varied gameplay over graphics.
Hundreds of different monsters in randomly-generated, unpredictable dungeons will strive to slay you by various means, and you counter - if you survive - by developing the skills of your choice and wielding mighty artifacts.
ToMEs races from Hobbit to Troll and classes from Swordmaster to Summoner allow for many different playing styles and a replay value that extends through years.
The only game so realistic that your scrolls and spell books will burn if you trudge in lava (unless you have gained immunity from some armour), you will dry up rivers to cast mighty spells, strike at orcs with blades attuned to slay them specifically, summon armies from a simple totem, and even forge your own artifacts.
There is an entire community to help you with the game, and it is far from static - ToME is a developing game, always improving. And best of all, its free.
Enhancements:
- Fix window position saving on Mac OS
- Remove buggy trap of Stair Movement
- Fix typo in one monsters flags
- Fix word wrapping in character sheet

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: Now includes a build target for creating a Servlet WAR file for delivering CSV, or KML(XML), formatted records over the web. KML formatted records can be imported directly into Google Earth (which also automatically retrieve periodic updates to the data) so that as new records come in to the MySQL database, they will automatically be updated in Google Earth.
- NEW: MySQL datastore server now has better error checking.
- NEW: The build-in logging facility has been updated with some additional features and provides an easier path for eventually porting to Log4J.

GMap is a Map editor for GPS maps that runs on linux. This project is a work in progress. GMap reads various formats and writes .mp polish map format files suitable for compiling using the cgpsmapper compiler.
I also have some notes relating to the use of GPS tools on Linux and the use of cGPSmapper on Linux and M$-Windows.
Currently the development is at an alpha stage. However it is starting to provide some basic funtionality so there is a copy here for anyone that wants to play.
Note that this is the only doc there is at the moment, it is incomplete and may also be slightly out of sync with the uploaded executable.
Main features:
- Display tracks and area (POLYLINE/POLYGON) features.
- Some POI support
- Editing of track and area features.
- Limited UNDO, currently should handle add, delete and move points. Split tracks. Convert a track to an area feature. Dont rely on it. Save often.
- Read and write data data to Polish format map data files. These are suitable for feeding to the cGPSmapper map compiler.
- Read tracks and waypoints from ".gpx" files (from gpsbabel or mapsource uploads)
- Read Tracks and points from google earth ".kml" files (not .kmz)
- Saves to named file or first input file. Original input is renamed to oldname;version (eg gmap fred.mp -> save renames to fred.mp;1 etc)
- Holds 2 sets of map data, one as a reference which is not written out. You can merge as many files as you like on read.
- Some handling of things with holes.
- Map warping. Allows you to warp one set of map data so it aligns correctly with another set of data. Example being to fix data estimated from images or maps against correct ground tracks.
- Knows something about the world being curved.
- Can read tracks, waypoints and current position from my garmin GPSMap 60CSx and a ForeRunner301
