Virtualization

Here is a post to prove that I am still a Software Engineer. 😉

Before starting, just think about the following questions..

• How will you reduce the hardware expenditure in your organization? Obviously, without reducing man power and selling the hardware 😀
• While developing a module, after reaching a milestone, have you ever tried to modify something in an effort to improve the solution and screwed up the whole thing and started from scratch?
• In such cases, have you ever said something like, “Damn!!! (Sometimes non-parliamentary words ;)) If at all I could save my work and restart from THAT point!!!”
• Let us say, you want to try out some system level programming and scared to try on your machine?
• Lets say, I have machine. I want to distribute it to somebody without him or me spending any money on hardware (Similar to 1st point)

The answer for all these is Virtualization.

What is Virtualization? In my words..
It is a technology where you create a computer using Software. This machine will do ALL the tasks done by a normal machine. This machine is called as a Virtual Machine (VM).(Atlast, I think I could explain it in layman terms.)

Lot of vendors provides software that creates Virtual Machines. To name a few software to create Virtual Machines: VMware, XEN.

These software provides easy ways for you to create virtual machines (provided you have an OS CD/DVD). Using these software, you can say, get me a machine with XX GB Hard disk, XX GB RAM, X processors. Obviously, you need to have enough Hard disk, RAM and processing power on the host machine.

A few terminology:
Host machine -> The machine that runs your VM
Guest machine -> The VM itself.

For creating an OS using the above mentioned software, you need to enable Virtualization in the BIOS of your host machine. You can google for the steps to enable virtualization in your machine as the steps vary depending on vendors.

One of the advantage of virtual machines is, You can take snapshots of the Virtual machine. So, whenever you think that you have reached a milestone, you can take a snapshot of the machine and revert to it whenever you want.

For doing my UT, I’ll just install OS, Install pre-requisite software, Test our product. In each stages, I’ll take snapshot. So that I don’t have to redo the whole thing from scratch. (Acting clever :D)

This post is just an Intro about Virtualization. Soon, will write a post about creating a Virtual Machine (VM) online in around 10-15 minutes and download it and start using it.

In short, I’ll Be Back!!! 😀

Inglourious Basterds

First blog in this new year!!!

One thing I would like to make clear when writing a review, especially if it is a book or movie. I WILL NOT POST ANY SPOILERS. If at all you find any, please leave a comment, I’ll try to either remove it or create a spoiler section and move it there. 🙂 Because, I want you enjoy the thrill when YOU read/watch.

While reading Harry Potter books, I came across a site that revealed a REALLY BIG SUSPENSE in the story. So, when that suspense was revealed in the book, as I already knew it, the thrill I got was significantly less.
Reason for less: Rowling was so good that I could not believe what the site said.

Let me start.

Yesterday, I watched this movie. I didn’t had high expectations before starting this movie. Anoop (Mentioned in one of the old blogs,) told me that he had watched this and he liked it. And told me that I may not like it.

I started watching this movie. Seems like Anoop was right. I didn’t like it but I loved it :).

This movie has five chapters. The first chapter has the introduction of our antagonist. The next one is the intro of the protagonist. (Trying to improve my english by replacing the common words like villain and hero respectively :D) This movie talks about Jews and is set in World War II time frame. Jews, WW II time frame… Rings any bells??? Yes!! It is a fictional story with THAT character. (I’ll leave it for you to guess who THAT is!!). In both these chapters, they’ll show how ruthless they are. Yes!! They.. Both the protagonist and the antagonist. Watch the movie for more details. And the next three chapters, I don’t want to talk about. Then I might reveal some spoilers.

One thing is, you can really enjoy the movie if you are a fast reader. Yes.. Reader. Because, most of the dialogs are in French and German and those dialogs are subtitled.

Starting from the first chapter, they have maintained a tension throughout in the movie. There are some nail-biting sequences. (Full tension!!!) If at all I had nail biting habit, I would not have had to look for my nail cutter today and spend time cutting my nails. Also, there are some real cool jokes too. If you didn’t laugh (at least smile) at the bar scene, You are not at all a human being. The screenplay was good. And the climax, WOW!!! Simply AMAZING!!! (Masterpiece!! Watch the movie to know why I have mentioned masterpiece here :))

One of my all time favorites.
Verdict: Must Watch
