Eleet Screensaver

Mon, 02 Jun 2025 00:00:00 +0000

A screensaver for use with Linux and UNIX, that pays homage to the classic space trading game of Elite. Eleet displays textured rotating OpenGL models of various spaceships, based on on those found in Elite. A random ship is chosen from a pool of 53 models and rotated against a starfield background, whilst the name of the ship orbits around it. Ships with exhausts will also emit thrust particles. Eleet supports Gnome Screensaver, KDE Screensaver and XScreensaver and is known to work on Linux, FreeBSD, OpenBSD and OpenSolaris

PingMon

Mon, 02 Jun 2025 00:00:00 +0000

Pingmon is a simple network monitor written in Perl. It is a console based program with a colour interface (can be switched to black & white) which means it can easily be used from a remote machine. You can configure which hosts to monitor, which hosts to ignore and which hosts cause a log entry if they go down. Scan speeds can be completely configured to control network traffic. It also supports the use of ICMP (ping request), TCP (echo port) and UDP (echo port) monitoring. It’s been tested on Linux, Solaris and IRIX but likely works under any OS with a reasonable perl implementation and a terminal supporting ANSI.

PyTZX

Mon, 02 Jun 2025 00:00:00 +0000

Pytzx is a simple API for creating TZX files in Python. TZX is a file format that represents a virtual tape or cassette. Cassette tapes were a common method of loading software on micro-computers throughout the 80s and very early 90s. TZX files are primarily useful with emulators to provide an accurate simulation of the loading process. Although TZX files are heavily biased towards the Sinclair ZX Spectrum machines, they can indeed be used with almost any platform of that era.

RemoteBox

Mon, 02 Jun 2025 00:00:00 +0000

RemoteBox is a GUI tool which lets you administer guests or virtual machines running under VirtualBox on a remote server or even the same local machine. VirtualBox is traditionally a desktop-side virtualisation solution. The goal of RemoteBox is to provide a GUI that should be familiar to VirtualBox users whist allowing them to administer a remote installation of VirtualBox. It does this via the VirtualBox API and SOAP interface which are exposed when running the VirtualBox web service. The RemoteBox client is known to run on Linux, Solaris, FreeBSD, OpenBSD, NetBSD and with a little effort, also on MacOS X and Windows. It has been tested against installations of VirtualBox running on Linux, Windows, Mac OS X and Solaris. In addition to this page, there is also a dedicated RemoteBox Site

RPMDiagram

Mon, 02 Jun 2025 00:00:00 +0000

A tool written and perl and built on top of GraphViz which draws a diagram of dependencies for an installed RPM. The diagram is written to an image file such as PNG or JPG.

Solar System Screensaver

Mon, 02 Jun 2025 00:00:00 +0000

A screensaver for Linux and UNIX that displays the planets of the Solar System (inc Pluto). A random planet is chosen and rotated on screen against a starfield background. As the planet orbits the sun, it transitions from light into darkness and a corona effect appears. Solarsystem supports Gnome Screensaver, KDE Screensaver and XScreensaver and is known to work on Linux, FreeBSD, OpenBSD and OpenSolaris

Zed80

Mon, 02 Jun 2025 00:00:00 +0000

Zed80 is a pure perl implementation of a z80 disassembler so it should work on any OS with a reasonable Perl implementation. For the curious ‘zed’ stands for ‘Z80 Experimental Disassembler’. Zed80 is a very simple disassembler that provides little more than an assembly dump of the specified file.
