Ubuntu Linux 11.04 (Natty Narwhal) released

Ubuntu Linux 11.04 (Natty Narwhal) has just released on 28 April 2011.

This version brings some new experience to the user.

The installation process involves less number of step.

Its default desktop interface is a new Unity Desktop instead of the traditional GNOME Desktop. The experience is now more Macintosh alike. You can notice the sidebar on its left, which doesn't found in previous version of Ubuntu. It took me a while to figure out where to access to my favourite applications in this new desktop.

The default office productivity suite has also shifted from OpenOffice.org to LibreOffice.

If you want to revert from the new Ubuntu Unity Desktop to the traditional Ubuntu GNOME Desktop, click here to find out the easy method to do so.

Cooling Unifi Broadband Termination Unit (BTU) using Vztec NC2165 notebook cooler

The black Huawei brand Unifi Broadband Termination Unit (BTU) has a metal casing. This BTU is supposed to work 24x7, and when you touch on its metal surface, you will feel some heat.

I use a Vztec NC2165 notebook cooler as its cooling solution. After installed, when you touch the BTU metal surface again, you will feel it is cool.

This Vztec NC2165 is USB powered. You can find one USB port in front of the Dlink DIR-615 Unifi Residential Gateway (RG), which can be a good choice for its power source. Alternatively, you can use any available USB port as its power source.

There are many USB powered notebook cooler in the market, most are just too big for this Unifi BTU, and their fan(s) might not match with the place of the BTU ventilation holes on top. As you can see in the picture, this Vztec NC2165 just suit perfectly, and it cost only RM15.

If you are also using Unifi HSBB, I recommend this inexpensive BTU cooling solution for you.

Cleaning camera lens with LensPen miniPro II

How do you normally clean the dirt, dust, grease, fingerprint, etc. on the camera lens of your digital camera and/or handphone? Using special cleaning fluid? Using brush? Wiping with microfibre? Wiping with cloth? Wiping with tissue paper? Wiping with your shirt? Never clean and let it be?

Regardless how you do the cleaning, I believe the bottom line is:

• The glass surface, as well as other parts of the device, won't be hurt or scratched
• The cleaning must be effective

I use a Canadian product called LensPen miniPro II to clean the camera lens of my digital camera as well as my handphone. It is very effective and inexpensive (selling at RM23 only).

LensPen miniPro II contains 2 cleaning parts. At one end, there is a retractable ultra fine brush to brush away dust and other particles deposited on the lens. At the other end, it has a special cleaning tip to wipe the lens. It is claimed that this special tip can do more than 500 times cleaning.

LensPen miniPro II has a compact size, easy to carry around or put in the camera bag. Its cleaning tip is small enough to be used for compact digital camera and the handphone camera lens. There are also LensPen products with larger cleaning tip for bigger DSLR lens. There is also LensPen MicroPro to clean even smaller lens surface.

To let you have a better picture of its length and size, here is my LensPen miniPro II putting together with my Canon PowerShot S95 digital camera.
