Centrist - GFY

 It is odd what centrist could do in the world and specially now.

The one side is religion defender, defending freedom and liberty etc. They want power to defend freedom of speech, decorum, values, ways of life, culture etc. for the honest working citizen. Mostly people like me :). They want good things and will take that because they can and they have power. Once they get power, never, ever have they even kept the pretence of these things, do whatever they want and just work (earn ?) for themselves. They leave power only after violence and death.

Th other side is mulla-left-liberal cabal - they want power, thus luxury, influence and other such things in the name of the weak and working class, honest workers. Mostly people like me :). They want good things and will take that because they can and they have power. Once they get power, they typically keep their luxury hidden. And none, not even once, have given up on power, luxury and such things without being forced to and mostly via violence and death.

So people like me - who want universal health and education, while somehow want that doctors and teachers make as much money as high end corporate executives do, or who want to act on things, create, breathe without stifling bureaucracy, or set up growth with honor without killing the eco-system and such things –  GFY. 

Ungrateful and entitled Middle class (Specially Hindu)

 No, "specially Hindu" part is correct. Not making this up. Our revered know it all, declutter of the clutter said so here.  https://www.youtube.com/watch?v=ybEGNLuJ1N0&t=2s

Mr. Gupta says, Hindu middle class is ( 4:02.) entitled and doesn't have gratitude for Mr. Manmohan Singh (almost at the last). Moreover, it is being just asked to pay a bit more - 7:04. 

Wow. just wow.

We should have gratitude for Mr. Manmohan Singh. For what Mr. Gupta? Because, he unchained one hand of two? Not both though.  After 30 years, Government (read pressure groups, privilege peddlers like so called journalist) can place or remove. Thats what they want, control all the time and wants middle class to accept them as their lord. 

Or we should have gratitude for an IT Boom, that changed things for youth in India 30 years ago. It was in-spite of Mr. Manmohan Singh or his political masters. It is still in-spite of them.

We are entitled. Really? "A bit more" - 6 months of 12 months earnings go in Tax. A bit more? God prohibit, if something happens to me, my kids have 50% chance of being on the street in next 3 years. " A bit more" will not ever protect them. So middle class is angry, because, it takes years to create a corpus which is clean and white. Tax that too.. leave nothing. We shouldn't be entitled to even basic law and order in our cities after 50% of tax, right Mr. Gupta? In a city like Bengaluru,  try asking to start AC in a cab sir? You would know, 50% tax doesn't even buy basic fear of law. Forget about any other city Sir, and we are entitled. Wow .. just wow..

Yes, Mr. Modi gets middle class votes. Because there is no one else is even trying to make India worth being proud for.  The other reborn leader is talking about "Ababdi vs Hissedaari". No call to "Aabadi vs Jimmedaari". Mr. Manmohan Singh did not bestow any favors on me Mr. Gupta. But his current political heirs are hell bent of taking away everything that middle class somehow created with 0% government support. 

What do we have typically for which we should have gratitude for? May be a flat for which middle class paid through his nose, almost double of what it cost. Got swindled then there still is no recourse. A car perhaps, for which  it pays world highest tax. And yes, these "Aabadi banam Hissedaari" folks actually wants to take that away as well. They have never made or produced a single thing. They are kings. They bestow whatever they tax. And they take their cut. Their biggest problem is that "middle class" has one hand unchained and even then doesn't give two hoots to them. They want to take away that. And their cheerleaders believe middle class is entitled.

Ownership

No, no, don't organize that.
Let it be.
don't set it right,
leave it as is.
let the dust be,
some day,I'll clean that,


With rough strokes, may be,
may be by throwing it away on the floor
owning it.

may be, it's a dream, long broken
may be it's a laugh
may be a very stubborn tear,
just leave that.

yeah, it's not beautiful, as a flower in a vase is,
but it is beautiful none the less,
you see, it's mine,
to own, to let it stay, to break, to loan,
to never get it back, to fight for it
to listen to complaints, to fix those, to ignore those

you see, when you organized that,
you took all,
now it is just a thing,
not a dream, nor a tear
not mine anymore.

Virtualization

Ages ago I created a small introduction on Virtualization with Ram Awasthi in TBSL. It was pretty basic and is reproduced here.

As the definition is very generic and in trivial terms, even a shared hard drive could be termed virtualization.

A lose definition could be "virtualization is a framework or methodology of dividing the resources of a computer into multiple execution environments, by applying one or more concepts or technologies such as hardware and software partitioning, time-sharing, partial or complete machine simulation, emulation, quality of service, and many others."

Popek and Goldberg virtualization requirements are considered to be the genric set of requirements to define virtualization.

As a technique it is used to increase throughput of the existing H/W by adding more so called virtual environments.

“Virtualization is a broad term that refers to the abstraction of computer resources. Virtualization hides the physical characteristics of computing resources from the user. This includes making a single resource appear as a multiple resources vice versa.”

It can be divided to many types based on objects: storage virtualization, computing virtualization (OS virtualization, application virtualization), and network virtualization.


With increasing support being built into the processors (Intel and AMD), now virtual environment give almost near native performance.
It is used in 2 kinds of environments
Desktop Virtualizations
Primarily done to reduce costs, reduce upgrade timeframes, getting away from proprietary systems.
Virtualization in Data centers
Primarily used for resource sharing and consolidation, easy manageability and isolation.
Usecases for virtualization in data centers

• Control ever increasing servers in a data center
• Reduce Power requirements
• Enhancing standardizations
• Legacy operations (Especially in cases where legacy tools are not required all the time and are difficult to change)
• Performance isolation ( By provisioning of resources)
• Via distributed virtual machines on demand network monitoring, on demand security audits, virtual DMZs can be achieved.
• CDN

In some case studies 15:1 virtual machines per hosts has been reported, with SAN connected with redundant paths.
Available Vendors

• VM ware (Individual applications available as virtual programs are also available)
• Microsoft Virtual PC and Virtual server
• Parallels Workstation
• HP
• IBM

FOSS Community

• Xen
• Win4Lin
• Sun virtual box(Free download for individual users)
• VMPlayers are available for free downloads and on top of this freely available linux distros can be installed.
• QEMU
• UML (User mode linux kernal)
• openVZ
• Linux-Vserver

Techniques
Virtual Machines
An emulator based approach, with Virtual machine monitors running to analyze executed code and make it safe on-the-fly for privileged CPU instructions.
Para Virtualization
This technique also requires a VMM, but most of its work is performed in the guest OS code, which in turn is modified to support this VMM and avoid unnecessary use of privileged instructions.

The paravirtualization technique also enables running different OSs on a single server, but requires them to be ported, i.e. they should "know" they are running under the hypervisor. The paravirtualization approach is used by products such as Xen and UML.
Virtualization on OS level
Similar to and in UNIX systems based upon chroot mechanism, it allows for multiple user spaces with in a single OS. Not as flexible as other techniques (i.e. Similar OS may be virtualized but a different family e.g Windows on a Linux hosts is not possible) but performance penalty is almost nothing. Such user spaces or instances (also called containers, VEs, VPSs or jails) may look and feel like a real server. In addition to isolation mechanisms, the kernel often provides resource management features to limit the impact of one container's activities on the other containers.

Abdominal Guards and population

Some relations are just weird. I mean, I read it somewhere - the abdominal guards in cricket were first used in 1874. And helmets in 1974.
Also consider that India is very populous and also very cricket crazy. Well, some ppl think with different organs :) .

Subtle difference in access modifiers in java & ruby

Just going through basics of Ruby and realized there is a slight difference in the behavior for protected and private access modifiers. From java to Ruby access modification differences are (other then syntax)
1. In Ruby default access to instance messages is public. In java the default method visibility is package.
2. In Ruby private access can be done only internal to the instance i.e. not even from other instance of the other class. In java that is allowed. Pretty much because in Ruby access determination happens at runtime.
