The Eye Of Horus is a monitoring and alerting tool for computers. Its mainly useful for monitoring network services (eg, HTTP or SMTP servers) and the internal status of Unix servers (eg, load, disk usage, process counts).

In that respect, its a lot like Nagios, but in my opinion its better. It lacks a few features Nagios has, but it is a very simple architecture to which they can easily be added.

Its a flexible thing made from independent modules with well-defined interfaces, making it easy to customise and extend, but out of the box itll monitor your servers and produce a nice HTML summary of their status - OK, the looks need a bit of work, but that will come soon, and it can optionally integrate with the excellent (and I mean excellent) RRDTool to store logs of statistics (response times, number of packages with known security holes, etc) - and link from the status page to nice graphs of the historical behaviour of these statistics.

HOW IT WORKS

The core of the system is horus-check.py, a Python script which reads a configuration file (specified on the command line). The configuration file specifies a list of services - either network services, in which case the host to run the check from and the host to run the check at are specified, or local services, in which case only the host to run the check from need be specified. In either case, if the host to run the check from is not specified, then it defaults to the local host.

The service types reference definitions in a file which is referenced from the configuration file. In the service definitions file, a shell command to check the service is given; this command must output service status in a defined format, as a single-line YAML list. The list must contain, at least, a single-word status (OK, WARNING, FAILURE, or UNKNOWN), then optionally numeric statistics, then optionally a status message. For example:

[OK]
[UNKNOWN]
[OK, { load: 0.5, users: 3 }]
[WARNING, { load: 3, users: 30 }]
[FAILURE, { load: 95, users: 300 }]
[UNKNOWN, { }, Could not find AWK executable]

When a check is to be performed from a remote host, Horus opens an ssh connection to that host. It is assumed that the user horus is run as will have an ssh key set up to enable it to ssh to all such hosts without requiring a password.

Having performed the checks, horus-check.py then:

Reads in the status database named in the configuration file
Updates the status database with the new status of hosts
Computes an overall system status (the worst non-unknown status of any checked service)
Examines the service dependencies, and marks any service whose state is no worse than might be expected (eg, no worse than the worst state of a service it depends upon) are automatically marked as quiet
Computes a list of differences between the old and new status (services added, services removed, services whose status has improved, services whose status has worsened)
If there are any differences, invokes a notification script (named in the configuration file) with them, along with the overall status
Invokes a logging script (named in the configuration file) with the new value of every statistic reported by the service checks; I will soon provide a sample logging script that uses RRDTool to generate nice graphs.

The status database (which is written in YAML, so easily accessible to user scripts) can then be used to generate HTML status report (see status.cgi).

Realms of Rivalry is an online tactical rpg. Play short skirmishes in random-generated game worlds.
The game can be summarized as an online graphical turn-based strategy/rpg game where you can play short tactical skirmishes with 2-4 players in small random-generated game worlds. The game is free and can be played either as an applet or downloadable client.
The time-limited turns (30-90 secs) give the game a semi-realtime feel, and the game has sometimes been characterized as "chess on steroids".
Main features:
- Community friendly game lobby where you can chat with others and join realms.
- Up to 4 players simultaneously battling on the same realm.
- Players control teams of 3 characters: Warrior, Archer and Mage.
- Time-limited turn-based gameplay.
- Random-generated game worlds (realms).
- CPU controlled monsters.
- Several weapons, armor, traps and other items.
- Occlusion calculation used in combat situations.
- Interrupts.
- Different types of terrain.
- Buy & sell items at vendors.
- Monster respawning.
- Ingame chat.
- Detailed end-of-game summary panel.
Explore the map and kill creatures to obtain weapons, potions, runes, traps and more to aid you in your quest for domination!
The game development has been very "test-driven" in the sense that the game quickly was made playable and that features and changes were added and removed continuously during development. This hopefully improves gameplay, but of course at the expense of dramatically increased development time.
Realms of rivalry was never intended to "soothe the masses", but were made entirely to match the game that we ourselves would like to play - something we have done for many, many hours :-) But of course, some of you might enjoy this game aswell, and that is why we decided to share it with you!.

The Ace of Penguins project is a X11 solitaire card games.

This package includes freecell, golf, mastermind, merlin, minesweeper, pegged, solitaire, taipei, and thornq, plus a solitaire toolkit so that you can write your own games.

These games are modelled after the Windows(tm) versions, with several enhancements, including a more colorful "Linux-y" theme.

Battle of Survival is a real-time strategy game using the Stratagus game engine.
The engine and the game are evolving a lot. Therefore, the game will work only with the version of the Stratagus engine matching the release !
Main features:
- New units
- More detailed maps based on full image. This uses the new lua map format in stratagus 2.2
- Improved UI
- New menu system

PHP Exif Library in short PEL is a library that lets you manipulate Exif (Exchangeable Image File Format) data. This is the data that digital cameras place in their images, such as the date and time, shutter speed, ISO value and so on.
Using PEL, one can fully modify the Exif data, meaning that it can be both read and written. PEL is written completely in PHP and depends on nothing except a standard installation of PHP, version 5, which was released on July 13th 2004.
Main features:
- Reads and parses both JPEG and TIFF images.
- Supports reading and writing all Exif tags.
- Supports internationalisation.
- Extensible object-oriented design. PEL utilizes the new features in PHP 5.
- Tested with SimpleTest (11 camera models tested, plus core tests).
- Fully documented with PhpDocumentor, see the online API documentation.

3D Spatialization of Sound is a Linux/X11 port of the 3D spatializer library from the CRC.

This program creates "directional" stereo sound from mono source. CRC folks told me I shouldnt have raised the sampling frequency without adjusting other stuff.

Oh well. This was a proof-of-concept type project anyway. I think to get correct 3D effect, you need to drop sampling rate back to 11025.

To Build the X11 implementation:

1. make
2. cp audio-filter /usr/local/bin
3. mpg123 -m -s some_music.mp3 | audio-filter | aplay -S -s 44100 -f s16l -

audio-filter is implemented as a filter, it reads signed 16 bit mono input at 44100 khz from stdin, and outputs signed 16 bit stereo, 44100 khz output to stdout. You can replace mpg123 with any sound source generating signed 16 bit 44100 khz mono signal. "aplay" is a sound player utility which comes with ALSA linux sound driver. You can use "play" from the sox package, or "ampctl", or any other sound player that would read 44100 khz, signed 16 bit stereo raw data from stdin. For "sox" play script, you would replace "aplay" command line with "play -c 2 -f s -r 44100 -s w -t raw -"

If everything is good, a 640x480 window will come up, with some cryptic writing on the top, a filled circle with an arrow pointing right, and a empty circle slightly to the right of the circle with arrow.

NOTE, that just like in the original Windows implementation, the axiss are reversed. The arrow on the "head" is pointing "forward". So, in the default startup configuration, the sound is located in front of the listener. Moving the sound source "up" moves it to the left of the listener, and "down", to the right. You can visualize this well if you turn your monitor 90 degrees counter
clock wise.

The filled circle with an arrow is your "head"
The empty circle is the "sound source"

You can move the "sound source" around by clicking the mouse at any position in the window, or by clicking on the "sound source" circle, and dragging it to the desired position. Soundfield will be dynamically updated as you do this.

You can move the "head" by moving the mouse to desired position, and right-clicking. The "head" icon will move to the new position and soundfield will be updated.

Beats of Rage is a tribute to Streets of Rage.

Originally intended as nothing more than a fun little private project, Beats of Rage soon became a very popular game which was ported to many platforms (Linux, Playstaion2, DreamCast, XBox and will go to run at others).

Senile Team strive to be your source for high-quality old-school games, graphics with character, well-chosen soundtracks and, most importantly, the solid gameplay we feel one can only find in the classic genres.

Attention: This is the executable file only. You still need to download the original DOS version for the data files.
