Cache Ubuntu Update to Speed Up Update and Save Bandwidth

If you have several Ubuntu machines at home, every time there is a new package, you will need to download the same package several times.
Just found out a package called squid-deb-proxy.  You will need to have a server and install

sudo apt-get install squid-deb-proxy avahi-utils

and in other machines install:

sudo apt-get install squid-deb-proxy-client

From now on, "avahi" on the server will advertise the proxy server in your network.
And when you download any package from any of your local machines, it will see the proxy server and download the package through the server.

Finally, Google Street View arrived at Hong Kong and Macau (only the southern half).   It will be very handy next time I go to Hong Kong and Macau.
Here are some places I visited last time I went back to Hong Kong and Macau.

New Toy - Nexus One

I got a new toy - Nexus One.  (Any good app I should try?)

 

After undated the Firmware to Android 2.1-update1, I got Pinch-to-zoom, Google Goggles and a updated Google Maps.  Some cool videos about Nexus One below.

Google Goggles - Search With Pictures Instead Of Text

Google Goggles is an application for Android phone that search the web with picture instead of using text.  Below are some examples from their site:

Search Landmark - Golden Gate Gridge

Enter Contact 

Search for Places - "The Diner", "Scarpetta" and "Comix Comedy Club"

They just added a new feature: Translate text in picture.  It's currently in beta testing for German-to-English translations only.  Check out the video in the blog: Integrating translation into Google Goggles.
