Geothermal heating

Article on heating or cooling home using geothermal energy.
Apparently the trenches needed for this system in the author's home is:
300ft long 5 ft wide 5 ft deep. That probably is the downside of this kind of system, requirement for large amount of backyard space.
But the technology seems very simple, using PVC pipes and a compressor and a heat exchanger, heat and cool your home with minimal electricity requirement. Sounds cool!

Stumbled into this article while following an article: http://www.popularmechanics.com/science/earth/4245896.html?page=1

ipod nano and accessories

(originally posted on 7/29/07)

I finally gave in and purchased ipod nano (about $190) - silver from costco on july 2007.
When i went to buy sleeves for ipod, i noticed they are all overpriced (although stylish).
I settled for Belkin F8Z060 Sports Sleeve for iPod nanos (Black)

for $15 at officemax. it comes with a protective screen overlay and armband and it is a silicone sleeve.

I like the nano and the sleeve!

Cut and Paste while using vncviewer

In order to transfer data through clipboard and cut and paste, while using the vncviewer (realvnc or tightvnc) on windows machines (dont know if it is an issue on other OSes), you should run the app: vncconfig.
This is an X app, you start it per display and leave it running in the background.
This has options to enable clipboard data transfer.
