AV Mode multimedia key works with natty narwhal on Vaio CS

Hi with the latest upgrades available for natty narwhal, i found to my surprise that the AV Mode multimedia key now works and brings up the rhythmbox music player on press. This is the first time in 2 yrs, since installing ubuntu on this machine, that i have any of the multimedia keys working.

Mind you this is the only key which works at the moment, volume change keys, forward and backward keys and capture button for webcam do not work.
I believe this is the first step in the right direction.

Although the rhythmbox starts with the AV Button, it leaves the machines unresponsive for a minute or so. But the machine recovers on its own....Natty is still alpha1,so hopefully as it matures, will fix the issue of media keys on Vaios....

Back pain and posture.

Nobody is immune to Back pain. It is the most common musculoskeletal condition, like tooth decay and the common cold, this is an affliction that affects a substantial proportion of population, at some point in their lives. This condition does not discriminate by gender, age, race or culture.

There are a number of surveys in many countries that reveal a point-prevalence of 17–30%, a 1-month prevalence of 19–43% and a life-time prevalence of 60–80%.

It has been said that backahe is the price the human race is paying for adopting a erect posture.
There are a number of factors which contribute towards developing backache like: Work environment and ergonomics, posture, psychosocial factors and spine/extraspinal pathologies. Sometimes these factors overlap towards causing this condition.

Common conditions that cause the back ache are: Disc pathologies, Injuries, degenerative changes in the spine, infections etc.

If your have chronic backpain, pain radiating along the thighs or legs, recurrent backpains, tingling or altered sensation in the limbs; please see the orthopaedician as it needs to be investigated.

In this article i will concentrate on backpain related to work and posture.

 Back pain is often a consequence of poor posture and stress on spine. This causes overtaxing of various tissues of the spine.

Stooping either in sitting or standing posture increases the strain on the spine leading to damage to intervetebral disks.








                                                                              

Knee pain in young IT Professionals

Knee pain in young individuals is a common condition, esp in individuals involved in sports, prolonged sitting or standing jobs, industrial jobs and even office jobs.

Most of these patients have

• anterior knee pain, which is a dull aching pain: 
• aggravated by activities like prolonged standing or sitting, going up and down the stairs, jogging or doing sports. 
• Some of them can get grating sensation on moving the knee. 
• There is no swelling or redness of the joint
