Todays computer have more power than what is required by a single users. Thanks to the Gigahertz race, processors are getting faster and faster. The result is that an average Joe uses only 10% of the processing.

The best way to harness this underutilised power is to get multiple users to share the resources of the same computer.

One way is Utilise NComputing device or to setup a dual-head display on your computer and follow this howto.

Nokia has developed a phone that charges itself using microwaves. It picks up waves from TV signals, radio and other mobile phones.

Finally all the radiations that’s been cooking our brains is finally being put to some good use.

Olympus just released its Micro Four Thirds camera the Olympus E-P1. It was Panasonic which introduced this concept by doing away with the Prism, thereby reducing the size of the camera and now Olympus is following suit.

Enough of technology, what does all this mean?

This means that you can have a small camera with inter-changeable lenses.

Whats I like about this camera:

  • 12 MP Camera
  • 3 inches LCD screen
  • High Definition video recording with stereo sound
  • Built in Image Stabilisation
  • HDMI port
  • Support for SD Memory, makes it easy to swap memory with other consumer devices. Thank god the xD format is gone :)
  • Adaptor for four third and older Olympus lenses, so you can use your existing lenses
  • Support upto 30 min exposure for those long exposures
  • Metalic Body
  • Good quality lenses
  • Dust reduction system
  • Audio recording to have your notes narrations
  • Art Filter for more creativity
  • Better compatibility with other 4/3rd lenses.

What I don’t like:

No Viewfinder? Come on Olympus, you know photographers better than anyone else. I like using the LCD but in certain conditions, such as when there is too much light, the LCD can’t be seen and thats when the viewfinder comes to your rescue.

However there is an optional viewfinder available if you must.

No Built In Flash. Which means you can’t use it for indoor evening parties. You do have optional flashes at additional costs. However you can’t use flash and optical finder at same time, as they both sit into the same slot.

Comparison with Panasonic GH1

Olympus Advantage

  • Image Stabilisation
  • Metalic Body

Panasonic Advantage

  • Electronic View Finder
  • Built in Flash
  • Faster Auto Focus
  • Vari-angle LCD, which means the LCD can be moved around to take the difficult shots.
  • 1080p video recording vs 720p of Olympus

Here is more stuff from DPReview.

43rumors was the first to report this camera, and has lots of more information.

Amazon has released the source code for its e-book reader Kindle.

And guess what it runs Linux.

Have a look if you are interested in the source.

Way to go Amazon!

When I boot up my Ubuntu system, it often says Routine check of drives and takes forever to boot up.

This is because the routine check is set to a number which is not very high if you don’t reboot often Which may be the case in a server but for a Desktop its an overkill, specially if you boot up a couple of times a day.

With a small change, you can boot up quicker and save time as well.

So here is the solution:

sudo tune2fs -c 100 /dev/sda5

Where

100 is the number of counts after which it should do a routine check.

/dev/sda5 is my ex3 file system, replace this with whatever is your partition number.

If you have more than one, you need to do this for all your ext3 partitions.
