Do you have trouble remembering phone numbers, PINs, social insurance numbers, etc.? 010 Memorizer is a program designed to help you easily remember numbers. The basic idea is that it is easier to remember vivid images, like orange juice gushing out of a geyser, then a number like 39174306. Using 010 Memorizer, you can convert a number into a word or phrase that forms an image in your mind. The conversion between numbers and words is done by phonetics: certain consonant sounds represent certain numbers and vowels act as fillers. 010 Memorizer helps you with this conversion by listing all words that can be used to memorize a number, and you just have to pick a word or phrase that you find easy to remember.

The Ham Intelligent Calculator, also called Hamic, is a program designed to simplify a number of calculations commonly used by Hams. It is designed for the Ham radio hobbyist, but may be useful to others as well. Hamic has a simple to use, but powerful graphical interface that allows solving simple circuits such as resistors in series or parallel, or more complex circuits such as L networks or T networks. As well, other calculations such as SWR, reactance, resonant frequency, inductance of an air core coil, and antenna impedance are supported. One of the more powerful features of Hamic is to solve for almost any unknown variable in a circuit; Hamic can even solve L networks without having to use Smith charts. Also, Hamic can easily convert between a number of different units. Once you have finished your work, your calculations can be saved to a worksheet and retrieved later. People interested in working with circuits or antennas should check this program out!

Syncplay synchronises the position and play state of multiple media players so that the viewers can watch the same thing at the same time. This means that when one person pauses/unpauses playback or seeks (jumps position) within their media player then this will be replicated across all media players connected to the same server and in the same 'room' (viewing session). When a new person joins they will also be synchronised. Syncplay also includes text-based chat so you can discuss a video as you watch it (or you could use third-party Voice over IP software to talk over a video).
