What if you are standing in an elevator and suddenly its floor tiles fall off ???
Simple use of a multiple TV screens by LG, with sticker tapes to give a GRID like feeling as seen on floor tiles. This is scary if you are not aware of such unusual elevators. Similar screens can be used to display news or important information of the building ( hotel, commercial complex or offices ), while you move from floor 0 to floor 58.

A TV commercial launched by Sinhgad Institutes. This is the place where I studied my Bachelor's in Computer Science. Its the first TV commercial ever ...
Studied computer engineering @ Sinhgad College of Engineering with an ambition to become a software engineer. At the beginning of my engineering career, I always doubted the correctness of the equation x = x + y , since the variable x cannot be on both sides of the assignment operator ( that's what we learned in our school days ) ... however this was just the beginning to the world of 1's and 0's. After 3 years of my course, I realized that I haven't learnt much about programming or applied the acquired knowledge, but rather its the way I think & my logic to implement things have changed. I had started thinking like a computer & a geek trying to know what's happening when a 'printf("Hello World")' command is executed.

You can get fired for doing your job well. Yes you read it correct, and its the current state of all jobs in the IT industry. So the question is how do I save my job ? What can I do to standout as compared to other peers ? I cam across this excellent video by Vivek Ranadivè, the CEO of TIBCO Software Inc. , who clearly guides us on surviving in a highly hyper competitive world today.
I completely agree on the punch line : "If you do everything that you are asked to do, and you do it really very well, you get a 'C' , but if you want to get a 'A' or 'A+' do things that nobody asked you to do..."

Jeopardy! is an American quiz show featuring trivia in history, literature, the arts, pop culture, science, sports, geography, wordplay, and more. The show has a unique answer-and-question format in which contestants are presented with clues in the form of answers, and must phrase their responses in question form.
Jeopardy is not a easy game like the tradional quiz which ask the "What is, Who is, Which is " type os questions which have only one answers. But Jeopardy is the other way round , from a clue/answer on needs to find the best possible question.
74-time Jeopardy! champion Ken Jennings, who has won a total of $3,172,700 on the show, and holds the all-time records for total game show earnings, lost to IBM's Watson - a super super computer.
Here's how IBM Watson works to search millions of books in fractions of a second to find the best possible question for the Jeopardy clue.
The Real Code and Logic behind WATSON :
When you read the word snapshot what is the first thing that comes to your mind is , "A Photograph which preserves the best moments of your life". Technically snapshot is very much the same with the difference that it preserves the state of some digital resource. In VMware a disk "snapshot" is a copy of the VM's disk file (.vmdk) captured at a certain point in time. This snapshot preserves the disk file system and the files stored on it which can be of any type (including all the operating system files). So if something goes wrong with your virtual machine, you can restore it to a snapshot which was working previously.
One can also create snapshots for different versions/service-packs on an OS.
Hence snapshots can also be looked upon as version controlling mechanism at OS level. So if your computer was shut down abruptly or gets infected by virus, just revert to a snapshot.
So how do snapshots really work ? There's just one Thumb Rule to VMware's snapshot technology : "Snapshots only store the differences between the current state and the original state". It follows the copy-on-write scheme with every subsequent disk access. Lets try to understand what that means ...
Consider that you have a text file with the word "COMPUTING" stored in it.
This file is a sparse in nature : which means it spans across multiple blocks on the disk. Step 1 below demonstrates this scenario. The black lines indicate the links on to the stored data. For demonstration purpose lets consider that each block on disk has only one character.
Note : The blocks shown above contain only one character and is purely for example purpose. In real the block size could be of say 1MB or a sector on disk.
Now when you take a snapshot another file named Snapshot1.vmdk will be created. When you create a snapshot, any changes made on the original virtual disk image are not made on the original disk, but they are written to a new (snapshot) disk file. This action is very fast as there is no need to copy whole virtual disk image.
Thumb Rule : "While saving changed data blocks in a snapshot, all modified block will be saved first , followed by blocks which were deleted as compared to base disk blocks." As seen in Step 2 , blue block is linked at the end of the snapshot1.vmdk
Lets suppose that you take a snapshot after you have saved the word "COMPUTING" in the file. After the snapshot you modify the file by changing its last two blocks (letters N and G circled above) and clear the letter I. The new changed word is "COMPUTER" as show in the Step 2. The blue block above is nothing but an empty block created by deleting letter I. The blocks in RED represents the new snapshot1.vmdk disk which contains only the changed characters.
Thumb Rule : "While reading any file in current state read only the data accessible by first level links, irrespective of number of snapshots and original data of the file."
Reading the first links of the "Current State" disk from Step 2 (Green blocks) , word "COMPUTER" is retrieved and the size of snapshot1.vmdk is 3 blocks (2 filled and one empty). However since its a differential snapshot file its size is much less than original base disk (9 blocks). Snapshot image size grows as you continue to change more and more data from your original virtual disk image (which remains untouched from the moment you took the snapshot).
Thumb Rule : "Size of a snapshot will always be less than the base disk, but in worst case it will be exactly the same size if all blocks were to be changed."
As seen in Step 3 , we now take another snapshot after saving the word "COMPUTER" in the file. On making more changes after snapshot2 , similar process is followed to create snapshot2.vmdk file. The new changed word in the file is "CONTAINER". As a result now neither snapshot 1 nor the base file are written two, but are still referenced. Snapshot 2 will store the new changes as compared to snapshot 1. If you read the first level links of the green blocks from top to bottom , the word "CONTAINER" is read with the fact that only 5 letters are stored in snapshot2.
Below are the list of changes made to the file
--------------------------------------------------------------------------
Step1 - Base Disk = COMPUTING
Step2 - Snapshot1 = COMPUTER
Step3 - Snapshot2 = CONTAINER
From the above scenarios its clear that taking snapshots in VMware involves only writing the differences in files changed from the time of the snapshot, not the complete virtual machine disk. This mechanism is similar to taking diff and patch in Unix, but in a more sophisticated way that diffs on a binary level with the knowledge of how a VMFS ( Virtual Machine File System ) is structured.
Now we have a clear idea about the Copy-On-Write Protocol - Every time a block from the base disk or previous snapshot is changed , copy it to the current delta or snapshot file, which implies that when you perform a snapshot restoration, it only has to rewrite the sectors that were modified since you took the snapshot. As a result snapshot revert is also super fast.
But the Question is, What happens when you revert to an older snapshot? The VM software throws away the contents of snapshot2.vmdk and starts over with reading contents from snapshot1.vmdk. During this all the Blue links in Step3 are replaced with Green Links. ( this is a similar strategy followed in deleting a node from a linklist ... Pure programming stuff ). Note : Links to Snapshot1 and Base are not changed.
There are two more important aspects of Snapshot management : Discarding a snapshot and Merging a snapshot (reverting to a non-immediate parent snapshot).

Excellent Linux video commercial which clearly shows how good things in the world are rejected , refused and laughed at... until it wins.Last statement of this video is really interesting and worth reading.
The whole idea is Microsoft always wanted to be in the driver's seat and creating its monopoly across the globe in the computer market. However we have some statements made by Bill Gates , Gartner Group and other competitors ,against the ability of Linux to excel in every field of computer.
Soon we have another criticism or rather a discouraging statement ...
"Linux isn't going away. Linux is a serious competitor. We will rise to this challenge." - Steve Ballmer [ 2003 ]
The whole idea is Microsoft always wanted to be in the driver's seat and creating its monopoly across the globe in the computer market. However we have some statements made by Bill Gates , Gartner Group and other competitors ,against the ability of Linux to excel in every field of computer.
Gartner clearly ignored the real power of Linux.
"Linux is the HYPE DU JOUR." - Gartner Group [ 1999 ]
Soon we have another criticism or rather a discouraging statement ...
"We think of Linux as a competitor in the student and hobbyist market.
But I really don't think in the commercial market we'll see it in any significant way." - Bill Gates [ 2001 ]
This seemed to be like the current marketing strategy - Make comments which will hide the real ability of a product.Finally Steve Ballmer, Microsoft CEO accepted with the below comments :
"Linux isn't going away. Linux is a serious competitor. We will rise to this challenge." - Steve Ballmer [ 2003 ]
Virtual machines on VMware ESX* hypervisors can communicate with each other via Virtual Switches, using the same protocols, as used on physical switches. A Virtual Machine (VM) can have multiple Ethernet adapters each with a unique IP address,thus imitating properties same as that of a physical computer.
Virtual Ethernet Adapters are one of the key features of VMware Hypervisor stack. This allows a VM to communicate with another VM and with other virtual switch. Shown below is the video tutorial by rocksolidtechnical on how to create a Virtual Switch on VMware.

Diagrammatically we can represent the multiple VMs communicating via Virtual Ethernet Adapters and Virtual Switches.Note the VMs are also capable of communicating with the outside physical network.

This project investigates in the history of human migration by analyzing DNA samples from millions of people living today. Launched in April 2005, the collaboration between IBM and the National Geographic Society is creating a comprehensive knowledge base of our shared genetic heritage, a unique resource that continues to refine our understanding of human history.
Ultimately we all have come from one single origin , the single unknown parent ??? Our genes have a link to this missing record and some critical information about our ancestors from 60,000 years or even more .
As project director Dr. Spencer Wells said, “The greatest history book ever written is the one hidden in our DNA.”
