Authority
The number of people protested on July 01 against the HK government was claimed 76K by the organizer; however the police department claimed 25K, which was 1/3 of the total number.
The fundamental of this is authority, neither of them was the reliable source; neither of them was able to defense their claim, by giving their 'proprietary' accounting method as the answer to the public. That's why we need a standard, could be a well-know standard, being carried out by them or any 3rd party.
It's nowadays a world of well-connected and information flowing freely among countries, these figure makes the world laughing, at least one of them making a silly, naive and irresponsible evaluation for the figure to the public.
There's many ways of accounting, we can simply leave this to the authorities drafting, enforcing and auditing such account methods. However, year by year, event by event, neither party stepped forward to trust other parties figure, or willing to use independent parties' method instead of their 'indiscoverable' one, they always claim themselves the authority and blindly ignore other parties figures or the argues from the public.
Seems it's not as important, as a company's annual financial report, mostly done by an authority - accounting film, and everyone could review all items listed in the report, have fact check...
Seems it's not as important, as public exam's grading; no one would trust the grading by candidates themselves, nor one single proctor.
Accounting for the number of people in the protest should not be political; it should be purely scientific, purely statistical.
I'm hoping that one day, there's some independent authorized parties become the authority of announcing such numbers. Of course, the way how they collect samples and calculate could be accepted and audited by the public.
If that day comes, everyone would know how they will be counted, in what condition will be counted as valid. The public could accept the unbiased information from authorized source, collected from much professional way.
Stop joking the public as fool. We need an authority.

A rejected gift"It's for you, open it."
"Sorry, I don't want it."
"It's for you, we won't take it back, take it."
"I don't need a gift."
He don't know why, why expressing his appreciation in a such unfriendly way.
Maybe, it's the first time, the secret of date of birth being disclosed.
Maybe, it's the first time, he don't know how to handle such unexpected.
Maybe, it's the first time, someone suddenly came into his private world.
He begins diluting the importance of festivals.
He celebrated with others, reluctantly, if no excuse; while only sharing privately.
In the past years, no one, except his mother was able to share the true happiness with him, when that day came.
For many years, he never told anyone, the day when he was born.
To him, he was not prepared for the changes.
Everyone needs a change; otherwise it's just as never existed, while he believes in eternality.
A gift brings him a surprise that out of 'definition', brings him also the moment of lost.
He rejected, it hurts any body, including him.
He did something wrong, to anyone, including himself, so he was in a bad mood since rejecting.
It's not to present the identity of uniqueness. It's the moment of emptiness and weakness.
When something not supposed to be found was found, he was both found and lost.
He was so strong, always ready for the severe challenges;
He was so weak, suddenly found himself helpless for such a trivial gift of appreciation.
A gift has opened a seal of his soul.
Reseal it by accepting, without a heart, to keep the secret of weakness;
Or, let it wide open, no one cares more.

Memory
Memory, some can't be forgotten while some can't be recalled.
Keep memory by alias – another piece of trivial memory.
Memory by recording: by photo, video or text, too intentional.
Photos can't be taken all the time.
Even you can, photos can't be keep all the time;
Even you can, photos can't be with you all the time;
Even you can, photos can't be shown all the time;
Even you can, photos can't bring you the same memory all the time;
Even you can, photos was just the dead-body of eternity.
It's a plain record of documentary.
Memory by alias: trivial but sometimes unforgotten.
Whenever drying my hair, slowly, memory of childhood flashes.
It was by mother's hands, gently and carefully.
Whenever able to spare sometime drying hair, the memory was recalled.
Whenever a certain piano was heard, I felt chilled.
It was a freezing morning, when the train door opened for hours without a reason; MP3 was playing that piano CD, again and again.
Whenever that music was played again, my feet was as in freezing air, as one trivial morning few years ago, in New York's subway.
Whenever spotting a certain city on a map, something pops up in my mind.
It was a remote city, at the corner of the world.
Whenever anyone asked which place was my favorite, I would reply instantly with its name, and short description for that island of rejuvenation.
Whenever that melody starts, I would follow until it stops.
It was any of my favorite song, sometimes not evil able to recall the names.
Whenever it starts, I was not able to get focus, until it stops, as I was singing with her.
Whenever short beep-beep-beep rings, I would get nervous.
It was a sound of pager calls for incident report, once part of my duty.
Whenever anything sounds like that, I had to tell myself: it's over; it's not your responsibility.
Whenever someone's name pops up, there's only an alias.
It's an alias that best description of that person; name was only an official record that tells nothing.
Whenever that alias exists and irreplaceable, the person was remembered.
Intention is not beautiful.

Network Communication in life<Chapter 0 – Introduction>
Why writing this book
I like learning and I'm a visualization style person in learning, I strongly prefer knowledge to be expressed and learnt in a casual way of games, examples or stories. When I was in secondary school or university, I was frustrated about the way instructors spreading out knowledge – for us, they were just pieces of information – or memento, those may easily lost their value after exam of end of the course. If you are lucky, you may still recall some of those from your family background, career or friends, but not all.
This book is written for those who were afraid of computing networking, but amazed by or curious of how general network communication works – how we get connected and connected so closely. It's also suitable for those with zero knowledge background in networking. This book is not meant to go deep into the technology side, it's not an introduction to the technology, it's simply a story book telling networking concepts from our real life examples, a 'pre-school' book for the network communication.
About the author
I've graduated with a Bachelor degree in Science, major in Mathematics. Now I'm working in a network security company as Network Security Analyst, for Distributed Denial of Service (DDos) detection and prevention.
This is a wish since I stepped my foot into IT field. I'm not a purely IT person, but a document guy, enjoy being the man-in-the-middle helping delivering communications between several parties.
I'm on my track to take the most challenging exam in the industry in computer networking – CCIE R&S (Cisco Certified Internetwork Expert: Routing and Switching track). This book will be completed this year (2009), as a 'supporting' document to the certificate, or to apply for a research master study in information security.
Words from the author
I was the same as many of you when I first heard of network communication – amazed. It's not an easy topic to express by IOS, TCP/IP, BGP… forget about those terms, there's no secret of getting understanding of those jargons, they are just another form of our day-to-day activates, just in another form. Within a year after graduation from university, I've forgotten almost all courses of complex number, differentiate equations… Lady for company administration asked me one day: "I don't know what your company is doing; boss told me we are doing something called DDoS, but I've no idea what is that." I explained and she nodded, I was pleased.
With only my explanation is not sufficient to understand those concepts, at least when you have read it the first time. It's something I can explain how to do that here – it's the sense to life, not just from the surface, you need a little bit more – the concept and logic behind them, keep asking if not sure. I'm not able to understand every field to become a generic 'Doctor of knowledge', learning in a interactive way is also an example of 'network communication in life', please do contact me if you have any question of this book or anything related to this book.

Coffee or TeaHe likes tea, she likes coffee.
He never drinks her coffee while she never drinks his tea.
He likes tea; he likes making teas rather than drinking them.
Among all teas he has, the one he like the most was green tea.
He likes those teas light in colour, pure and innocent.
He demands quality of teas, as well as the quality time of making teas.
Every time he is in a bad mood, he will start making his green tea.
He is sentimental especially when seeing tea leaves stretching, dancing and rejuvenating.
He knows she might not understand why he's doing so, but she never asked.
Tea leaves must be complete;
Water must be pure;
Glass must be spotless;
Noise must be eliminated;
That's his quality time, making his cup of tea, alone.
She likes coffee, she likes tasting fresh, little and little.
Among all coffee she tasted, the one she like the most was Cupertino.
She likes layers of premium Cupertino, tasting layer by layer like discovering.
She demands environment of having coffee, as well as every bite stimulate her joy.
Every time she is in a good mood, he will spend hours with a single cup of coffee.
She is falling in love when the each layer brings her each taste of joy.
She knows he don't want to understand why she's doing so, and he never noticed.
Coffee must be fresh;
Sweetness must be a little less;
Coffee cup must be pure white;
Seat must be conformable;
That's her quality time, drinking her cup of coffee, alone.
