Mouse turns 40

The humble computer mouse celebrates its 40th anniversary today.

On 9 December 1968 hi-tech visionary Douglas Engelbart first used one to demonstrate novel ways of working with computers.

The first mouse that Dr Engelbart used in the demo at the Fall Joint Computer Conference (FJCC) was made of wood and had one button.

Much of the technology shown off in the demo inspired the creation of the hardware and software now widely used.

A day of celebration is planned in California to mark the 40th anniversary; with many of the researchers behind the original demo reunited to mark the event.

Paying the price

Office workers using computers constantly are at risk from repetitive strain injury (RSI), more recently known as non-specific arm pain (NSAP)
This is a collection of symptoms covering work-related upper limb problems, which can affect the hands, wrists, necks, arms and upper back

TIPS TO AVOID RSI

Try to avoid prolonged or repetitive tasks

Use both hands

Take short breaks rather than one long one

Keep warm - cold muscles don't extend properly

Report pain or other symptoms straight away

Use a headset when talking and typing

Rotate work tasks to vary routine

Follow guidance from your individual assessment

Customize your mouse settings to use it occasionally with your other hand

today was my close friends birthday..we had lots of icecreams!!!....:)...

opened up my pc to do some cleaning...it was so filled with dust...!!!

obg,virus

hmm..finally our obg[obstetrics and gynaecology] postings[of 6 weeks] will be over today..it was quite a good posting where we learned many things and saw some really good cases...

we had internals on wednesday and my case was a lady[obvious] with a Rh -VE pregnancy[which means her blood grp is O-ve and her husbands is B+ve]...the problem in such pregnancies is that the fetus being Rh+ve[which acquires husbands blood grp-Mendelian principle] triggers a immune reaction in the mother which eventually results in its[fetus] rbc[red blood cell] destruction[similar to what happens in a mismatched blood transfusion] resulting in serious complications like jaundice in the baby...my patient had similar complication which unfortunately resulted in delivery of a dead baby:(...hope next time she conceives a healthy child..:))...

my pc is not working from a few a days due to some worm attck....feel like am in a jail....now at my aunts place and trying to blog here as much as i can:)...
