Globalism
Several days back, I received an mail from my old best friend (Anggia) about a short documentary film in Globalism. Actually, I've know all these issues since I was a under graduate student, but there is something new here.... Everything is showed for people that grows up in the CAPITALISM spirit and environment in their perspective also.
How companies (e.g., FORD, General Motors) have enormous power.. even greater than Denmark or South Africa which are not categorized as 3rd World Countries.
The most "great" (I don't know it is amusing or embarrassing) thing is the film uses INDONESIA as the case.
I do believe about DEMOCRACY as one of the best way to the prosperity, but again it is not the only ONE. Recently, The west world advertises that being a democratic society is the only way to get prosperity. The liberation (personally, I aint totally agree with this term) of Iraq and Afghanistan are some examples to make some countries being democratic one.
I think.. we can't say what is the best thing for others, let them to decide which one is the most fit for them. We can give an example how democracy work and motivate them to do the same, and not more than that.
Democracy, Globalism, Emancipation, Freewill are one package that become "big-password" for a better society.
Do you agree with this?
Personally, I agree ... but those definitions are not the same with the ones in western countries.
We (Indonesians) have different values therefore we need to adapt those notions to our context.
Globalism can be seen Socialism among the rich and Capitalism among the poor (as the film said).
The rich more and more gets more money, and the poor more and more gets more debt. I don't oppose the idea of global-economy, but I don't like if the producers (labors) suffers and the owners lives in richness.
The world should be fair......
Please, God help us.. to solve this circle.. :(

Starting from laziness
Recently, I'm absent in writing in this Blog.
I don't know... Why... maybe I'm too preoccupied to writing the things that are not part of my obligations.
I thing I need to start this habit again.
Huffa... [wake up from the laziness]
Anyway, Laziness... I think it is the last tings that I'd admit even if it is so obvious. ;-)
As today, I was blaming all the schedule as the main reason why I need move on with my thing.
Today, I don't have any particular agenda but it is still no single artifact is resulted.
So it is obvious what is the reason for all of these.
--
We can see the mistake of others even it is so small
Conversely, we "always" overlook about our mistakes though they are so fatal

Understanding
Often, I think I understand something very well. (maybe "think" should be replaced by "feel")
But....
When I start to explain it by a writing artifact, then I feel I hit a wall.
Maybe Einstein is right
"You are not really understand it, when you can't explain it in simple manner".
Thinking is reduction of feeling
Speaking is reduction of thinking
Writing is reduction of speaking
so.... once I can write about something clearly and simply.. than..I can be proud that I really understand it.

Does the GOD exist?
I have several times discussion about the existence of the God with several of my friends.
This time, I'll try to answer one of statements that intends to refuse the existence of the God.
I call IT as the God, and it doesn't limit from a belief that believes with multiple Gods/gods.
One day, there is a man, called Bob, that wants his hair and beard are trimmed such that it looks better.
Therefore, he goes to a barbershop.
During the barber, called Charlie, does his task, they involve in a discussion about many things and one of them is about the existence of the God.
Bob says, "I don't believe if the God exist"
Charlie says, "How come? don't you see many of his creations?"
Bob says, "Mmm, but as you see.... if the God is merciful and beneficent then how come so many people are in hunger and stay in poverty and sick".
Charlie says,"So ?"
Bob says, "So there is no such thing that we call God. Even there is so He is not as nice as we think because He lets it happens".
Charlie is silent and try not to oppose the Bob's opinion.
After everything finished, Charlie pays the fee and leaves the barbershop.
While he is standing in front of the barbershop, he sees a beggar with awful hair and bread.
Suddenly, Charlie shouts, "I do believe that there is no barber in this world".
Surely, Bob feels offended about that statements.
Bob responses, "I'm a barber and I exist, so you're totally wrong".
Charlie says, "If he exists why there is people with awful hair and bread? even he stays exactly in front of a barbershop."
Without any further comments, Charlie goes continuing his day.
Lesson learnt, Barber exists but a beggar doesn't come to him to trim his hair, and if there is a beggar.
In the case of God, THIS THING exists and we just need to come and ask HIM for help.
are we so arrogant such that we still demand that the God helps us even we don't tell him what we want?
--
before I thought that
if the GOD exists then there is no poverty
and I think this premise is too strong
so I refine it: if the God exists and we ask HIM for help then there is no poverty dfd
--
Further question:
how about if we have already asked HIM a help ?

Resilience
What does it mean Resilience system?
does it enough by measuring.... using availability?????
Need an answer??? :(
does it enough by measuring.... using availability?????
Need an answer??? :(
Availability and Reliability
Those words.. in common passwords in secure and dependable system (i.e., critical system).
In Avizenis et al. [TSDC,2004]
- Availability : the readiness of the system to provide a correct service
- Reliability : the continuity of the system to provide a correct service
based on these definitions, it seems both properties are going in the same polarity. [Hypothesis] For instance, if a system is highly available then it means the system is also reliable.
However, I don't believe about that because if there is an attribute/a property is a subset of another than we shouldn't measure the system with both properties.
At least it is belief in Decision Science community.
In software engineering, we always have them (i.e., reliability and availability) as non-functional requirements, and we can assess how good the system using how is the achievements of the system towards its NFRs.
So if the hypotheses are correct than we should drop one of them (either reliability or availability)
Eureka!!
[1] http://www.weibull.com/hotwire/issue26/relbasics26.htm
[2] http://www.barringer1.com/ar.htm
They explain how both property are related but the are not going in the same polarity or direction.
They have intersection between them but not sub-set (as my hypothesis).
Moreover, in [1] it states that reliability is the part in calculating availability.
Availability is refined as the probability that a system is not failed or undergoing in maintenance when it needs to be used.
Reliability just represents the probability of a system will operate when it needs to be used.
Reliability doesn't take into account the fact that a system can have a failure/downtime.
It only measures the number of failure within certain period, or probability of having failure within a certain period of time.
Availability takes into consideration how much time that is necessary to make the system back into operate mode anymore.

Availability takes into consideration how much time that is necessary to make the system back into operate mode anymore.
Availability = Uptime / (Uptime + Downtime)
orMTTF / MTTF + MTTR
MTTF stands for Mean-Time-To-Failure, it means how much is the average of time between failures
MTTR stands for Mean-Time-To-Repair, means how much is the average of time to repair the system for a failure
But we can simply remove reliability and it can be represented in availability because
Availability of a system can be decreased even when the reliability of the system is constant. It is because the MTTR is increased or the other way around.
So.. I hope you all understand what is the difference between two properties
--
PS:
In IEEE Transaction in Secure and Dependable Computing, [Avizenis, 2004] defines that dependability of a system are characterized as: availability, reliability, integrity, and maintainability.
so my next question.. I think we can derive availability from reliability + maintainability
;-) ... still think

SENANG - HAPPY
I don't know, maybe I don't want to know, WHY I'm very full energy and seems happy aura around me.
I like it.
Maybe because less than a month I'll be in my hometown with all my families, my old friends and INDONESIAN FOODS.
I wish I can do all my to do lists here before my departure, so I can have a peaceful holiday
Indonesia GUYS, please please give me your cellphones, I'll call you as soon as I settle down there
See you.. :D
