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.

Cyberduck is a great free FTP / SFTP application for OSX.

Download it here.
