The TD Waterhouse Share Cost Calculator now provides the share value required for a buy to become a profitable sell. The calculator returns what share price, and percentage, increase is required, when all conversions and fees are applied, for a stock to become a profitable buy to sell. This added feature is intended to help make decisions on what volume to buy and help guesstimate your investment time.

DropCopy is a insanely easy way to share files over your local network. Thanks to bonjour and it’s simple configuration, it is the perfect program for quickly sending files to other users on your local network.

There is a iPhone version too, Mobile DropCopy. There is a lite version, and the full version (which is $4.99).

If you’re in a Apple-centric LAN it’s perfect. Unfortunately there are only OSX and iPhone versions.

CUPS (Common Unix Printing System), is running by default on OSX systems as the print server. The web interface allows you to easily administer the CUPS server. You can even have it send an RSS feed to a printer when your computer starts.

The ability for a user to be on a site and have the web server cause an action to occur on the site, via ‘push technology‘, is soon to be realized at the HTML 5 leve. Although this type of interaction has always been available; through Flash, Java and Javascript. It’s finally being brought-up to the HTML level as noted in W3C documentation. The Stray Orange blog has a good post relating to HTML 5 push technology.

TeamViewer teamviewer.com is a free VNC program ( control a remote machine from your machine), that is very easy to set-up and use.
Highlights are:

• Free for public use
• Cross-platform friendly (OSX and Windows, no Linux though)
• Breaks through firewalls
• Uses an uber-strong backbone connection, so less lag than a VNC that uses public networks

Specials shout to JMSTP for introducing me to it.
