Memtest86+ scans your RAM for errors.

This tester runs independently of any OS – it is run at computer boot-up, so that it can test all of you memory. It can output a list of bad RAM regions usable by the BadRAM kernel patch, so that you can still use you old RAM with one or two bad bits.

Memtest86+ is based on memtest86 3.0, and adds support for recent hardware, as well as a number of general-purpose improvements, including many patches to memtest86 available from various sources.

A convenience script is also provided to make a grub-based floppy or image.

Ophcrack is a Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a GTK+ Graphical User Interface and runs on Windows, Mac OS X (Intel CPU) as well as on Linux.

The ophcrack LiveCD contains a full linux system (SLAX), ophcrack for linux and rainbow tables for alphanumerical passwords. The liveCD cracks passwords automatically, no installation necessary, no admin password necessary (as long as you can boot from CD).

Avira UnErase recovers data that have been deleted from the hard drive – either accidentally or as a result of a virus infection, an uninstaller or defective software. The danger of important data being lost forever is averted with Avira UnErase.

Fresh Diagnose is a utility designed to analyze and benchmark your computer system. It can analyze and benchmark many kinds of hardware, such as CPU performance, hard disk performance, video system information, mainboard / motherboard information, and much more…

Key features of Fresh Diagnose:

• System Information: Scanning your system and give a complete report about your computer’s hardware and software, for examples: mainboard information, video system information, PCI / AGP buses information, peripheral (keyboard, mouse, printer, etc.) information, Windows registry settings, and network information.
• System Benchmarks: Testing your system performance, such as CPU, hard disk, CD/DVD ROM, and compare it with other systems.

Use this free software to learn more about your computer and its components, detect / diagnose problems or errors in your computer, and increase your computer’s overall performance.

ZS4 is video editing and compositing software which aims to provide media experts with a facility to combine a variety of media types (currently photos, videos and audio files) into one (or more) output file(s).

ZS4 can be used like an object oriented photo-manipulation program with a timeline: things that can be manipulated in a photo (workshop) program can be manipulated in ZS4 using parameters which alter over time.

Main Features:

• Unlimited* number of audio, video and picture tracks
• Unlimited number of video/audio effects for every track.
• Produce video with a resolution of 8×8 or 16000×16000 (~200 Megapixels / frame) and many sizes in between
• Full automation control for all track and effect variables using keyframes (cropping, zooming, panning, volume, rotation, opacity, key-color etc…)
• Full cross integration of audio and video. (noise gates triggering video effects. video brightness controlling volume etc.) Here is an example video.
• Looping of both audio and video signals simultaneously, with adjustable cross-fade on loop boundaries.
• Manipulate the flow of time, forward, backward, speed up and slow down smoothly.
• Grouping of video/audio tracks into sub-groups (submixers) which can then be manipulated (faded/rotated/effected etc) as if they were a single track.
