Random thoughts on Brain

This a incomplete thoughts on human brain and would complete this article with more details in near future ...

Brain Memory structure is one of the best structure in the world.Its semi fluid state is the best form to store any information. There is a need to design computer hard disks the
same as our brain.The brain memory can be divided into different logical parts namely,
Living instincts Memory
Professional or Working memory
Relational Memory
Basic Logical Memory and
Advanced Knowledge Memory.

When a person is affected by amnesia ,he could be losing one of those above mentioned memories and still can survive with other memories being intact.

The working of brain memory can be classified into different categories as below:
1)Replace
2)Upgrade
3)Forget
4)Merge

Any day to day activity can be classified into one of the above categories.

Brain memory works like a parallel comparing machines. There is a separate thread for each smell,video,audio and sensation data we have ever experienced.
Whenever a new thing is seen ,its compared with existing video,audio,smell and sense part of the brains in parallel and if its not present already its added to the existing list.
If the data already exist then its upgraded and the final output is sent to our thought network.

Say, if one of the video or audio or smell or sensation thing is matched to new seen thing ,we may remember some forgotten old experience. Dont confuse this to deja-vu. Its something like you smell food in a restaurant and you remember an incident that happened in your college canteen long time back.

Pirate Bay introduces Image Hosting site

As most of you already know Pirate Bay has launched an "uncensored" image
hosting site,Bayimg.com !!







At the bottom of every page you see : “NO COPYRIGHT. NO LICENSE.”“When you uploaded
the picture, you wrote a removal code,” a Bayimg FAQ section states. Users (who are trying to
pull their pics) are then reminded that a removal code is “Kind of like a password. Now type it
in and noone will ever see that picture again!”

It allows people to host rar and zip archive files too upto 100mb.Hurray!! now you can hide your personal files in image format and store it freely on the web!!


I disapprove of what you say, but I will defend to the death your right to say it. ~Voltaire

Hide doc,txt etc files in jpeg photos

Here I teach you how to hide your confidential documents,text,Excel and other small files in jpeg photo format.
Other than you, whoever clicks on the jpeg file, they see only a picture. Only you know how to open this secret and confidential file!!.
This trick works for both Winzip(which am using here) and Winrar and many "other tools" which I wont disclose here ;)



Step 1: Let say you have a photo called “a.jpg” which you use as bait to hide your secret file “confidential.doc”
(You can use txt, xls or any other small file instead of a doc file)

Step 2: Now Zip “a.jpeg” and “confidential.doc” file into “confidential.zip” file.
Ie, select a.jpg and confidential.doc and right click à add to zip file

Step 3: Now add the zip and jpeg file into another jpeg file using simple DOS command as shown below:
Copy /b a.jpg + confidential.zip final.jpg

Step 4: Now if you open final.jpg using Winzip you see both the files as shown below. If anybody else clicks on final.jpeg
They just see the original photo in an Image viewer.

Please comment if you have any doubts or queries. Also let me know if you have more interesting tricks!!

Assign Drive letter to a folder

Do you use a particular folder very often on your PC??Do you feel sick of going through all the navigation hierarchy to access the contents of that folder??Ok one way to circumvent it is to create a shortcut to that folder on your desktop. you just need to right click the folder :goto sendto and select "Desktop(create shortcut)".
There is one another way to do the same which I think is more geeky!!Here we use a MS-Dos command called "subst" or "SUBSTITUTE" which creates a drive letter on your MyComputer linking the desired folder.
For example you need to create a drive letter for a folder say "D:\jdk1.5.0_07\demo\jfc\Java2D"
Open Dos using "command" at the "Run" menu



Type subst f: "D:\jdk1.5.0_07\demo\jfc\Java2D" then enter
Voila a drive letter with F: is created in your Mycomputer

Interesting Rule of 72

I know most of you know this already(sorry to bore you guys !!) . Just writing it down for blog sake.

Anyway theres something called Rule of 72 which helps you a lot if you worry about your saved money.
The rule says to find out how quickly any money invested will double, simply divide 72 by the rate of interest you have invested.This is providing you dont touch the money and its grows in compounding nature.

Examples
If your money is invested at 8% it will double in 9 years (72 divided by 8)
If your money is invested at 10% it will double in 7.2 years (72 divided by10)
