Our task must be to free ourselves… by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty.

One shot two birds; Captcha and Recaptcha technology

When you are surfing the internet sometimes you are required to solve something like a puzzle with some blurred words and it is needed in order to access the required page or create an account.

We know it is a much annoying thing and it is a must. Though most of us know it is for nothing but for the security purposes. Yeah! but there are lot of things inside this and I thought about giving some better information about this technology.

Lets move to the history first. Actually Captcha stands for Completely Automated Public Turing Test to Tell Computer and Human. The technology was founded by Luis Von Ahn in year 2000, based on turing test which was conducted in 1950. The Captcha was came out in year 2000 and was replaced by Recaptcha in 2007 to get use the valuable human hours.

Captcha gives a simple puzzle with one or two worlds and decide weather the the user is a machine or a human by checking the response for the puzzle. The words in the Captcha puzzle is created in a way that  computer program may not identified it and human brain would do it.

The only problem plugged with this technology is wasting the valuable time. So Luis Van Ahn, the founder  and his team came up for a solution for that and the solution is called Recaptcha technology.

Here the words we used for solving, imports from old scanned books that have to be digitized. Actually the words are words  that can’t be identified correctly by the coputer program for the digitization process. Here we got the advantage that the ability to get solved unidentified words by the program and export them. This is done using the solved puzzles by human. So by 15thDecember 2009 it has been able to digitalize most of the issues of New York Times (1851-1980) using this Recaptcha technology.


Difference between Man and Woman

Have you ever thought about the ways we are thinking. It is actually different according the gender. A man think a way that totally different with a women and their brains works as different ways. So have a look at this…

Men cannot concentrate on one task at the same time, But women can. As an example women can cook while talking over the phone but man cannot do both tasks at ones. They will stop either cooking or talking.

Language skill of women is greater. They can easily learn many languages but has low analytical skill. But for men it is difficult to learn languages. Even so men have a higher talent in solving problems. For an example man can drive a vehicle fast. He can analyze the speed and position quickly whereas women takes a long time to analyze those data.

Lying is a very hard process for the human brain. That is why it takes some time to prepare when you lying. Women can easily lie but men can’t, they will be caught most of the time. So keep in remember that women are big liars….!

A man can analyze a big problem one by one successfully. If a women have a problems it is difficult to handle that for her. Instead, she tell that all to someone and then she does not worry about those problems being solved or not.

Expectations of men are status, success, solutions, big process, etc… But Women want relationship, friends, family, etc…

If a women unhappy with her relations she can’t point on works and If a men have problems with his work he can’t happy with relations.


speed on demand; Intel turbo boost technology

 

 

 

Intel turbo boost technology is a way of increasing the fundamental operating frequency of processor cores. This mechanism allows to increases the processor performance when it running below it’s power, current, and temperature specification limits.

This turbo boost technology implemented with Intel’s Nehalem , Sandy Bridge and Ivy Bridge  based CPUs is optimized with Intel 2nd and 3rd generation CPUs and hence this is used on them. The turbo boost technology is enabled or disabled only on demand and it is done by a switch in BIOS, there is no any user controllable option.

 

 

 

The dynamic frequency power sharing method used for graphical intensive applications is works with this technology and the processor core operating frequency may be higher than their maximum rated values. This action will not affect badly because this happens temporary.

 

 

Is turbo boosting actually working? And so how we can monitor these things? Yes there is a tool from Intel that can be monitored the actions of cores. This tool can be downloaded from here. This tool works with every CPU that supports the turbo boost technology. You can see the supported CPUs and Operating systems below (Taken from the Intel’s web site)

 

Supported processors:

  • Intel® Core™ i5 Processor
  • Intel® Core™ i5 Mobile Processor
  • Intel® Core™ i7 Processor
  • Intel® Core™ i7 Processor Extreme Edition
  • Intel® Core™ i7 Mobile Processor
  • Intel® Core™ i7 Mobile Processor Extreme Edition

 

Supported operating systems

  • All Windows 7* OS versions (32 and 64 bit)
  • All Windows 8* OS versions (32 and 64 bit) – Legacy Desktop mode only
  • Windows Vista* no longer supported
    (detects and does not install on Vista-based PCs)

I LOVE YOU DAD

When I was born, you were there.

When I was fail, you were there.

When I say my first word, you were there.

When I took my first step, you were there.

First day at school, you were there.

I still haven’t even finished my studies. It’s good or bad I know you will be there for me all the time. So I want to tell

“ I LOVE YOU DAD “


HOW TO INCREASE OPERATING TIME OF YOUR LAPTOP BATTERY


Sometimes you may have experienced that the unavailability of continuous power from your laptop battery when you are in a long travel, waiting in a lobby or in a long trip. Actually battery power is the key factor in using a lap top in a place without the main supply. Here are some factors that help to keep the battery power some more time. I hope that you will enjoy this article and this will be valuable for you.

Defragmentation of the HD drive

The regular defragmentation of the hard disc drive is not only help to increase the speed but also keeps data very efficient manner

Try to avoid using of external devices

Unplug all the external devices such as USB drives, external hard disc drives, external mouse, pc card, external speakers and also disable Wi Fi, Bluetooth since they are suck more power.

Pause or stop unwanted programs and scheduled tasks

Keep stopping the firewall and scanning processes when you are not on internet. And stop the other startup programs when they are not vital.

Make sure that your CD DVD drive is empty

After you using a CD or DVD do not left it in the drive. Some amount of power is taken to the disc drive in order to spin the disc. Instead of the CD or DVD you can try by making virtual ROM using software such as Microsoft virtual ROM.

Lower the brightness of the display

Try to calibrate the display brightness to the lowest level and turn off the display when not required because the display is a device that sucks more power in a laptop.

Use hibernate option

Using the hibernate option is better rather than keeping the sleep (stand by) mode. In standby mode the display and hard drive turns off while memory is powered and processor is in idle but in hibernate mode the computer completely shuts down keeping the current data on the hard disc by making no power consumption.

Manage your tasks

Actually you should know what kind of programs requires more power. Works on an office document consumes much less power rather than playing a game or using a more graphic intensive program.

RAM

A relatively large RAM reduces the load of virtual memory on the hard disc which is a more power hungry device. It also increases the speed and decrease the time for accessing the hard disk.

Battery

Modern laptop comes with a Li ion (Lithium ion) battery which has no problem with partially discharge and recharge like old NI MH (nickel metal hydride) batteries. And the thing you should know is complete discharge is not suitable for modern batteries (Li ion). When you fully deplete a lithium battery and don’t start to recharge for a while because it will unable to hold charge.

Packing the battery

When you are not going to use the battery a long time make the battery so as the charge is 40% of its maximum and remove. Remember to keep the battery in a cool place.
