Yet Another Virtualization Intro: Virtualization and Client Server Technology

Isolation implies the independence virtual machines afford. Virtual machines are completely isolated from hosts and other machines. This provides the security that if one machine crashes the rest of the machines will be unaffected. This isolation also ensures data control. Machines can only communicate through specifically configured network connections. Data cannot infiltrate or affect other machines or applications.

Encapsulation is similar to the abstraction and information hiding that characterizes virtualization. It is defined as the combination of elements to create a new entity. For example, OOP (Object-Oriented Programming) languages like C++ and Java use encapsulation to create high-level (abstracted) objects. In virtualization, an entire virtual machine and its contents are encapsulated so it can be saved as a single file. This makes it incredibly easy to copy and move. Encapsulation resonates with virtualization in its tendency towards hiding the details to make dealing with objects easier. This is accomplished by hiding complexity with a simple interface.

Redhot Future Of IT Part I :Marketing yourself as IT professional

I had promised about the "RedHot IT Future Series" and so we discuss here how you should market yourself EFFECTIVELY as an IT professional in this new (and dangerous) web age! Web is the place where you're a hero today and villain tomorrow. While there are lots of professionals who are active on the web, not all are enjoying a good reputation as they got "personal" with others and got into a cockfight. The passive IT professional has nothing to lose but nothing to gain at all!

I know "marketing" might seem as a greasy term but the idea is to have the truth about you out there. You know you're a good person and your family knows that you're really smart person but the rest of the world doesn't!

So the question is how do I market myself on the web as a true "nouveau IT professional". A guy who companies will be tempted to pick up the phone as say "Hey, we wanna talk with you. Can you fly over to Palo Alto (or Guatemala or Johan…

Redhot Future Of IT Part 2 :Virtualized Workplaces

Click on the title to hear what I have to say, alternatively click here to listen to what I have to say here.

So what is a virtualized workplace? Does it mean it does not exist? That it's virtual? Well in a certain way YES. This is where the future of our workplace is going to be. Well it is already a reality in some countries.

OK lets start by asking ourselves these questions:
Do you really bond with your colleagues? (think Team cohesiveness)
Do you spend great amount of hours talking about great things that you will do together? (think collaboration)
Do you really feel that you give 100% at work? (think effectiveness)
What do you really miss at your desk? (think personalization)
Is your desk comfortable enough? (Again think optimizing personalization, OK you have done your best to make it your place)Does it really matter to your employer that you are there for him/her? (think commitment)
Or do you get micromanaged over petty issues? (think mismanagement)
Do you see your employees perfor…

A Collection of Threnodies : Part 1

Whale Fall
-----------------

Dress me up in my new threads
clasp my greasy palms
grease my hair
I'm ready for the fall


Watch at all the decadence
watching the avalanche
I'm slipping down
losing my buoyancy


What's become of us
where have we come
this far, this close
close to the doors


I hear them, sublimal chants
I'm on the run
I race through the human sea
I am the king!


I'm the slave
to my own undoings
I'm the jester in my courtyard
We jest as we run


We're strolling on that thin rope
we grope as we rope
we're true heros
we're the survivors


we're the scavengers
we're the friends
we're the lovers
we're the unbred


Soon awaiting the fall
we're lurking on us
we're osedaxing us
we're soon going to be done
we'll soon be arrested




*osedax(bone devourer, newly discovered marine genus) feeds on a fallen(sunken) whale carcass(which is also called a whale fall). Read more here
