Screen savers save nothing

"Enable screen savers to save power!"
You must have heard it a lot...but its nothing but a myth with current generation computers.

It takes more power to display graphical images on the screen,especially a CRT monitor.
So,if you want to save power, instead of enabling screen savers,configure your system to put monitor to sleep after a period of time.You can also set system to shutdown after a long period of inactivity if you want to.

Still,if you want to show a screen saver,chose one with minimum white..a complete black screen might save some power.

In Linux,you have many attractive screen savers...many of them on black themes.You may choose one of 'em or choose the first option(Blank Screen).Also remember to set your monitor to sleep after prolonged idle time.This applies to Windows also.

I used to have Linux screen savers with 10 minutes timeout,and I have enabled random screen savers.Now I changed it to Blank Screen with same timeout.Also my monitor goes to sleep after 25 minutes of inactivity.

I boot my system using BIOS RTC at night for scheduled downloading,that too with monitor and speakers off...just the cpu and router remains powered up.After 8.15 if I don't attend to system,it shuts down automatically.

I am mentioning all this,so that if someone in similar cases wants to save power,they can follow my model or use a better one.I have seen many people(even I used to) keeping system on overnight so that downloads can be done later...but most of the motherboards support Booting over RTC...use that to minimize power usage.

Wish all a happy and green computing...signing off...

Thought Controlled Applications

With the hunt for seminar topics...started the soaring imagination..my imagination.

I thought up 2-3 things that could change the way we live..if it were ever implemented.
I have mentioned about them in a fictional setup in my personal blog.
Here I will try to put down the specifications about these ideas and the issues I face.

The topics are kind of spawned from my deep interest in A.I,Neural Networks,Data Mining and the concept of web.All those who have heard about/played Neural Network Mapping would know my interest(or craze..as some see it) in understanding deep concepts of the mind and extracting it...and also the effort to connect it to the vast web containing the products of millions of brains and hearts...(actually billions and also hands,toes watever..)

Ok idea number one..in its raw form..is translating thoughts to a language understandable by softwares...mainly web search engines.A lot of doubts would arise in everyone's mind on hearing such ideas...one being the ability of machines to read and interpret thoughts...and even if did so...(actually brain signals have been utilised so far..never heard about any solid breakthrough in understanding thoughts)..the issue of utilizing it in its full strength.

I don't know if I can bring forward all the arguments and counter-arguments about this idea that I had over a period of time and write it in this post(if i do so...i fear this wud be a dynamically changing post,which wud require a reader to refresh page occasionally to read more)

My proposal is to use a nano device that resides in the brain(implanted) and can monitor brain signals.I assume that by the time this technology is operational,there would have been some breakthrough research that would allow us to atleast get an idea of what is being thought(i.e identify formation of thought and convert this into abstract form that can be used to uniquely identify the thought).It should be able to distinguish between my perception of an idea and another person's(which is quite different).What I think when I hear 'tree' is quite different from what you might be...Once this abstract form is available..it is transmitted out as a magnetic signal that doesn't affect normal working of body or other devices.

An external device (I called it mind-pod..:P),reads this data and can use it for any application.Here I am trying it for searching the web.This is tricky.I have to use an advanced AI to create a set of keywords from the abstract form that would then be used to fetch accurate results from teh web in the ordinary way.I felt this is a revolutionary idea..but depends a lot on future technologies and as a IR man,only the small AI is involved..which might well be done with some AI and Data Mining.My original design had design and concept flaws,so I propose this.The abstract form maybe used for any other innovative applications as well..actually it would open up a plethora of opportunities for application development....

The second topic is similar...its called dream analyzer(Dreamfix).Its faar more advanced than the previous..it should be able to read dreams and make a list of possible inferences.Its application would to be salvage useful ideas after a nap..after all sleep enhances thought processes and creativity!!!
