While I was surfing through a forum about GRE exams I saw some wonderful puzzles.
From those puzzles,I have posted some here....Solving them involves lateral thinking...




1.There are three houses, and three utilities: gas, electricity and water. Your task is to connect each house to all three utilities. Therefore each house will have three lines and each utility will also have three lines. However, you cannot cross lines. You cannot pass lines through houses or utilities. You cannot share lines. Can you draw the 9 lines required?




2.Three people check into a hotel. They pay £30 to the manager and go to their room. The manager suddenly remembers that the room rate is £25 and gives £5 to the bellboy to return to the people. On the way to the room the bellboy reasons that £5 would be difficult to share among three people so he pockets £2 and gives £1 to each person. Now each person paid £10 and got back £1. So they paid £9 each, totalling £27. The bellboy has £2, totalling £29. Where is the missing £1?


3.Once upon a time, and old lady went to sell her vast quantity of eggs at the local market.
When asked how many she had, she replied:


Son, I can't count past 100 but I know that.
If you divide the number of eggs by 2 there will be one egg left.
If you divide the number of eggs by 3 there will be one egg left.
If you divide the number of eggs by 4 there will be one egg left.
If you divide the number of eggs by 5 there will be one egg left.
If you divide the number of eggs by 6 there will be one egg left.
If you divide the number of eggs by 7 there will be one egg left.
If you divide the number of eggs by 8 there will be one egg left.
If you divide the number of eggs by 9 there will be one egg left.
If you divide the number of eggs by 10 there will be one egg left.
Finally. If you divide the Number of eggs by 11 there will be NO EGGS left!

How many eggs did the old lady have?



Solutions:

Read the solutions only after making a genuine attempt in solving the above puzzles.

1.This puzzle is a classic one which has no solution in 2D. However, if you place the items on a doughnut shape in 3D you can solve it. In the picture below, E is linked to 3 by going over the top and re-entering through the hole in the middle.



2.We have to be careful what we are adding together. Originally, they paid £30, they each received back £1, thus they now have only paid £27. Of this £27, £25 went to the manager for the room and £2 went to the bellboy.(This puzzle was used in a tamil film Rassaiyah for a comedy scene involving vadivel!!!)

3.25,201 eggs.

This puzzle has a few different methods for finding the solution, one of which is:

Find a number X into which all of the numbers from 2 to 10 divide evenly. You can do this by simply using 2*3*4*5*6*7*8*9*10, but you can find a smaller number by finding the prime factors, a subset of which can be used to form any number from 2 to 10. 2*2*2*3*3*5*7 will do. This comes out to be 2520, and is the lowest number into which all the numbers 2-10 divide evenly.

We can add 1 to this number to satisfy the first 9 constraints of the puzzle (the remainder of 2521/2, 2521/3 ... 2521/10 is one), but this does not satisfy the last constraint, divisibility by 11.

Fortunately, we can multiply X (=2520) by any integer and add 1 and we will still satisfy constraints 1-9. So what Y do we multiply X by so that (X*Y) + 1 is divisible by 11. 2520/11 has a remainder of 1. Thus two 2520s divided by eleven would have a remainder of 1+1 = 2, and so forth...so ten 2520s divided by 11 would have a remainder of 10. This number plus one would divide eleven evenly, as well as also satisfy the first 9 constraints - thus 25201 is the answer.

Hope you liked these puzzles...

I have been writing poems for quite some time in tamil (which happens to be my mother tongue).But I have not seriously tried to make one in English.Today I thought about it and made a poem.The title of the poem is My little rose.This idea came to mind as I was gazing at the red rose in my garden.I wanted to share my poem with you.Hope you have the patience to read the full poem.


My little rose

My little rose ,
you look so happy....

You have been stolen,
From my garden.
My little rose
Yet,you look so happy!

Your thorns failed,
In saving you.
My little rose,
Yet,you look so happy!

You miss your friends,
You miss your mother,
My little rose,
Yet,you look so happy!

You are lying on my grave.
My little rose,
Is that why
you look so happy?

My little rose,
You look so happy....

This is my first poem.
This did not turn out as bad as I expected.

Do you believe in ghosts??
If so read the post...
If not then you will start believing in ghosts.....after reading the post and seeing the video...

CHECK THIS VIDEO.......BUT BEFORE DOING SO..... PAUSE THE VIDEO AND LET IT LOAD.......IN THE MEANTIME READ THE DESCRIPTION AND THEN SEE THE VIDEO.....

Hey Folks,This one is really wild, but make sure you read the info below before you view the video and turn up the volume if you can. This is a car advertisement from Great Britain. When they finished filming the ad, the film editor noticed something moving along the side of the car, like a ghostly white mist. They found out that a person had been killed a year earlier in that exact same spot. The ad was never put on TV because of the unexplained ghostly phenomenon.Watch the front end of the car closely as it clears the trees in the middle of the screen and you'll see the white mist crossing in front of the car then following it along the road....Spooky!Is it a ghost, or is it simply mist? You decide. If you listen to the ad, you'll even hear the cameraman whispering in the background about it near the end of the commercial. A little creepy but it seems to be authentic!


Googlebot

A Googlebot is a search bot used by Google. It collects documents from the web to build a searchable index for the Google search engine.

If a webmaster wishes to restrict the information on their site available to a Googlebot, or another well-behaved spider, they can do so with the appropriate directives in a robots.txt file.and by adding a metatag with meta name as Googlebot and meta content as no follow.Googlebot requests to Web servers are discernible from their user-agent string 'Googlebot'.

GOOGLEBOT


Googlebot has two versions, deepbot and freshbot. Deepbot, the deep crawler, tries to follow every link on the web and download as many pages as it can to the Google indexers. It completes this process about once a month. Freshbot crawls the web looking for fresh content. It visits websites that change frequently, according to how frequently they change. Currently Googlebot only follows HREF links and SRC links.

Googlebot discovers pages by harvesting all of the links on every page it finds. It then follows these links to other web pages. New web pages must be linked to from another known page on the web in order to be crawled and indexed.

A problem which webmasters have often noted with the Googlebot is that it takes up an enormous amount of bandwidth. This can cause websites to exceed their bandwidth limit and be taken down temporarily. This is especially troublesome for mirror sites which host many gigabytes of data. Google provides "Webmaster Tools" that allow website owners to throttle the crawl rate.

HOMEPAGE OF COPYSCAPE




RESULT OF COPYSCAPE SEARCH FOR MY BLOG



It is cool website to prevent plagiarism...But I am unable to find the principle behind it's working...

But the sad part of the tale is that you can check a website only 10 times a month for a free account.You have to have a premium account for unlimited checking.And he is charging lot of money for that.

Key Catcher

Capture 262,000 keystrokes (over 160 pages)!




This is a device that can be connected to a keyboard to record all keystrokes. It has a changeable password, keyword search, enable/disable option, and stores URLs. Records 262,000 keystrokes and does not require any software. Monitor unauthorized access to your computer or your network. Use it to troubleshoot or make fixes by tracing back through a users command sequence.
Key Katcher plugs in between your keyboard and your computer. A microcontroller interprets the data, and stores information in the non-volatile memory (which retains the information even when there is a loss of power.) This means that the Key Katcher device can be unplugged, and the information will not be lost.
To access the recorded data, you simply type your password in a text editor and the Key Katcher comes to life. A menu is displayed with options to erase data, view data, search data for keywords, change password, or disable the device.

Some neat features of this gadget:
Available in the "Magnum" 4MB size, 256K, 128K or Mini size.
It is Portable - move it from computer to computer.
Installs in seconds - Just plug it in.
Uses no system resources. Truly runs in the background.
