A letter to a girl friend who is getting married to someone else!

Hey…hhhhhhhhhmmmmmmm sorry Hi,

Don`t know what to address you with friend, dear, darling, sweety…

I know that you are good, fine and healthy (you showed your health certificate recently). I am also good but could have been better. Some heart problem has started. Ok you forget it.

Embarrassed to hear that you are getting married to an exported Indian (now in US) guy. But still Indiais GREATTT!!!.
You could`ve looked for an Indian guy like me. Ok forget it.

But, It`s hard to digest for me (so having medicine for proper digestion) and I feel depressed that why are you not marrying me? I spent so much of useful and useless time with you. I can never forget our yesteryear`s life in near and far future. Anyway, I wish you many many happy returns of your future.

I heard that the guy looks handsome and nicely paid. I too earn a lot here in India. But cost of living in US is high and comparison with savings both stand in same position. I am going to gym regularly and facial wash often (you know that) to look smart. You were appreciating my bulging biceps (hope you haven`t forgotten). I think am comparably looking smarter than that guy except that I don't have French beard as am comfortable with Indian beard. Ok you forget it.

You told that he has invested on shares. But, I have invested on you (ice creams, chocolates, movies, trips, pizza, disco, recharge your sim, gifts, your scooty tires, etc.) without expecting any returns. But I got your friendly love and caring which is very precious to me. It`s Ok forget it.
He is from very good family background seems. I am not from bad family. My family is world famous in my area. Ok forget it.

You told me that he don`t have any girl friends. I don't believe this but still without a girl friend how can he realize the essence of love? See at least I have one, that's you. Ok forget it da.
I am wondering what more in him? What less in me? But still I wish you happy married life forever. Let him keep you happy always else I feel like killing him in my dreams. please don`t tell him about this, otherwise he may kill me.

My sincere request: If you are blessed with a baby boy after your marriage (5-6years)you keep my name to your kid and love him a lot. If you are booned with a baby girl keep my wife name to your kid (I`ll inform her name once I get married).

My gentle reminder: Please don't tell him about our so called friendship, because he may be possessive and your marriage may breakup. You know I was very protective towards you, never possessive. Ok you forget all those.

Don`t invite me for your marriage. I will not come and create any nuisance there. You send me your marriage DVD, I will watch alone in a dark room silently with my broken (damaged) heart. I`m handing you to your husband with my heavy heart (my heart weighs in pounds which is costlier than US$dollars).

Before your marriage: I am your friend, guide, care taker, joker, protector, slave, transporter, listener (to your junk words), everything for you.

After your marriage: I am a big problem for your life… Error! Filename not specified.
I recommend: Don`t forget to forget me after your marriage. Even though it's difficult for me to forget you. Somehow I will convince myself.

I will wait for 2-3 years after your marriage to become normal. I will marry to a girl my parents show me without uttering a single word even though how bad she may be.

Please ignore my grammatical bugs (you know am not rich in English language-please adjust).
Then what else? I will tell you more, you see, you know,… no, it's Ok forget me… bye… Error! Filename not specified.

Ur`s… sorry not Your`s,
What can I say, boy friend, friend, am confused… forget da… take care lifelong… Error! Filename not specified.

Learning Mainframes - 1

Ok! So I have decided to dirty my hands with mainframes. Its because I have some spare time to work with something new. And the interface for mainframe looks kewl. You feel in control, the feeling you get with old unix machines unlike the hanky panky (and ridiculous) windows!!

I am no genius in mainframes. So what I will try to do is, collect information from internet, books, people and will dump it down here.

Obviously, it will be gradual with a flow in it because I am myself doing it for the first time. So we will start with some introduction, and will go into details more complex day after day.

I WANT TO THANK YOU EVERYONE FOR THE INFORMATION PROVIDED IN THIS AND FORTH COMING POSTS. MOST OF THE TIME I WILL BE COLLECTING INFORMATION FROM VARIOUS PLACES AND WILL BE DOING MIXING PIXING SO AT TIMES IT WILL BE DIFFICULT FOR ME TO GIVE CREDIT TO THE ORIGINAL AUTHOR. BUT ALL KUDOS TO GEEKS OUT THERE. I RESPECT YOU FROM BOTTOM OF MY HEART. PLEASE WRITE TO ME IF YOU WANT ANY THING OUT OF THE BLOG WHICH YOU OWN, AND I WILL BE MORE THEN HAPPY TO RESPECT YOUR OWNERSHIP.

That said, let's start:

- By Lance H. Vaughan

The "new paradigm" (so called) proclaims that a clustering of small, limited architecture machines, interconnected by elaborate topologies, is the or going to be the wave of the future. Lost to a nontechnical senior management (as most of the firms have) is the fact that in implementing this new computational model they are at the same time eliminating the most powerful, comprehensive, and sophisticated class of computing platforms ever brought to the marketplace - MAINFRAMES.

The essential characteristics of a mainframe are: rapid and continuing evolution, general purpose orientation, hardware implemented solutions, and the criticality of user input to all of these processes.

"A mainframe is a continually evolving general purpose computing platform incorporating in it architectural definition the essential functionality required by its target applications."

"Mainframes used to be defined by their size, and they can still fill a room, cost millions, and support thousands of users. But now a mainframe can also run on a laptop and support two users. So today's mainframes are best defined by their operating systems: Unix and Linux, and IBM's z/OS, OS/390, MVS, VM, and VSE. Mainframes combine four important features: 1) Reliable single-thread performance, which is essential for reasonable operations against a database. 2) Maximum I/O connectivity, which means mainframes excel at providing for huge disk farms. 3) Maximum I/O bandwidth, so connections between drives and processors have few choke-points. 4) Reliability--mainframes often allow for "graceful degradation" and service while the system is running."

1) Maximum reliable single-thread performance: Some processes, such as the merge phase of a sort/merge (sorting can be subdivided...) MUST be run single thread. Other operations (balancing b-trees, etc) are single thread and tend to lock out other accesses. Therefore, single thread performance is critical to reasonable operations against a DataBase (especially when adding new rows).

2) Maximum I/O Connectivity: Mainframes excel at providing a convenient paradigm for HUGE disk farms; While SAN devices kind of weaken this to some degree, SAN devices mimic the model of the Mainframe in connectivity "tricks" (at least internally).

3) Maximum I/O Bandwidth: Despite the huge quantities of drives that may be attached to a mainframe, the drives are connected in such a way that there are very few choke-points in moving data to/from the actual processor complex.

4) Reliability - is reliability. :P




Next post: We will start with Evolution of OS/390 moving on to MVS and so forth. (Don't worry about the jargons. Even I don't have any idea). Mainframe is a big machine which can do huge calculations and store large amount of data. (ye ye !!)
