[Tech] C call Lua function assigned by Lua

2009-05-15T10:23:00.003+08:00

Today I just want to write a programming which is C and Lua call each other. But I want to pass a function pointer into C from the Lua, and Lua can receive this function pointer to call that function and return the value which is returned by thant function that pointed by that pointer.

This is the expample of that code:

C Code in luacaller.cpp

extern "C" {

#include <lua.h>
#include <lualib.h>
#include <lauxlib.h>
}

#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include <iostream>

using namespace std;

static int ReCall(lua_State * L);

const luaL_Reg EngineReg[] = {
{"ReCall", ReCall},
{NULL, NULL},
};

static int ReCall(lua_State * L)
{
int b = lua_tonumber(L, -1); // fetch the first argument passed from Lua Script
lua_pop(L, 1); //Pop the top one element from the stack
int a = lua_tonumber(L, -1); //fetch the second argument passed from Lua Script
lua_pop(L, 1);//Pop the top one element from the stack

if (!lua_isfunction(L, -1)) //Judging wheather it is a function object the top element of the stack
{
printf("From C: function error!\n");
return -1;
}

int ref = luaL_ref(L, LUA_REGISTRYINDEX); //fetch the function reference value
lua_pop(L, 1); // Pop the top one element from the stack

lua_rawgeti(L, LUA_REGISTRYINDEX, ref); //get the function object from the table passed from script and put it on the top of the stack
lua_pushnumber(L, a); // push the first argument into the top of the stack
lua_pushnumber(L, b); // push the second argument into the top of the stack

lua_pcall(L, 2, 1, 0); //recall the script and pass all the arguments
return 1;

}

static lua_State * L = NULL;
void InitialLua()
{
L = luaL_newstate();//Init the Lua virtual machine
luaL_openlibs(L);//Open all the std library
lua_gc(L, LUA_GCRESTART, 0);//call this function in order to garbage collection
luaL_register(L, "engine", EngineReg);//regist the functions open to the script

luaL_dofile(L, "lua_script.lua"); //call lua_script.lua file
}

void Test2()
{
lua_getglobal(L, "CallC2"); //call the function named CallC2 which is in the Script File
lua_pcall(L, 0, 0, 0); //No arguments and No Return value
return;
}

int main()
{
InitialLua();
Test2();
return 0;
}

LUA Code lua_script.lua
function Add(a, b)
print(string.format("Add %d+%d=%d", a, b, a+b))
return a+b
end
function Sub(a, b)
print(string.format("Sub %d+%d=%d", a, b, a-b))
return a-b
end

function CallC2()
local ret = engine.ReCall(Add, 2, 3); //Call back the "Add" function of ReCall which is in the engine and pass two arguments (2 and 3)
ret = engine.ReCall(Sub, 2, 3); //Call back the "Sub" function of ReCall which is in the engine and pass two arguments (2 and 3)
end

OUTPUT：
Add 2+3=5
Sub 2-3=-1

This is just a example for the test personally

[Tech] Orbit ! A simple Web Framework

2009-05-06T21:38:00.001+08:00

Orbit is an open source web development framework written by lua. And it is simple to use and understand. may be it will be the next generation web development tools I think in the near furture.

Let's see what is in it. Orbit is composed with 3 Module. and every module is idenpandance form others. There are

Module orbit : all the application API are in this Module, and this module include some method about the web application API you need. there are two main part in this module "app" and "web", "app" include all the API about running an application and managing an application. "web" includes all the API about the HTTP function. you can get data from the HTTP send by client. also it has the API about outputing data to the browser. Totally this is core of Orbit.

Module orbit.cache: From the name, we know that this part of Orbit deal with cache, Orbit allow you to put the data into an cache either in memory or filesystem. It is easy to use and understand. you can easy to build your own session module with this part of functon.

Module orbit.model: Orbit also provide the database API to developers, orbit.model is an module for that. you can easy to create ORM (Object-Relation Mapping) between Logic Object and Database Object. This module provide a lot of API to do the DB Operation through the Object.

So much, Orbit is so simple, and you can really find that is a good way to build your own Web Application with Orbit.

[Trip] to The Zoo

2009-05-03T10:12:00.005+08:00

I still remember that he is a boy who has full fill with the happiness all day long. You will always see the smile in his face whenever you meet him. But today a big argument occured between Jone and him.

A puzzle the teacher send to every body makes everybody busy. Jone and Paul have been assigned into the same group. They need make a programm which is about the car renting. The request of this homework is a little complex. Jone feel tensional about that homework. So she tell me to help her to finish that. We spend four days and make a mainly part about this project. And the project have finished 80% already. But the others of Jone's Group have do nothing about that yet, at the end of the deadline, they have a meeting each other, Jone show them this programm, and all the people feels good except Paul, he thinks that he have do nothing in this group, and he also thing that Jone intent to exclude him out of this group. Jone have a go-around with him. and she also very sad.

Jone tell me all the content about that thing, She also feel that it is not fair to her. I think so, all the guy want to make this project be good, noone will thing like as Paul thinking about. Good luck for them. and Hoping all the thing recover originally.

[Song] You Raise Me Up

Josh Groban - You Raise Me Up

when i am down and, oh my soul, so weary;
when troubles come and my heart burdened be;
then, i am still and wait here in the silence,
until you come and sit awhile with me.

you raise me up, so i can stand on mountains;
you raise me up, to walk on stormy seas;
i am strong, when i am on your shoulders;
you raise me up… to more than i can be.

you raise me up, so i can stand on mountains;
you raise me up, to walk on stormy seas;
i am strong, when i am on your shoulders;
you raise me up… to more than i can be.

there is no life ╟ no life without its hunger;
each restless heart beats so imperfectly;
but when you come and i am filled with wonder,
sometimes, i think i glimpse eternity.
you raise me up, so i can stand on mountains;
you raise me up, to walk on stormy seas;
i am strong, when i am on your shoulders;
you raise me up… to more than i can be.
you raise me up, so i can stand on mountains;
you raise me up, to walk on stormy seas;
i am strong, when i am on your shoulders;
you raise me up… to more than i can be.
you raise me up… to more than i can be.

[Program] Sample of Java Remote Method Invocation

2009-03-03T02:33:00.003+08:00

Hi Jone,
Here is the code sample of the Java RMI. It composed with four java code file as:
IRMI_Base.java : this file is the base class of this RMI function, It is an interface in java and four function prototype defined in this interface.

RMI_ServerLogic.java : this file is function of this server logic. content of the four function defined in IRMI_Base.java are implementd here. if you will modify this project as your homework, you should change these function. if you change the function define, please don't forget to change the defination in IRMI_Base.

Main.java : This file is Server main class the entrance of all the server logic, here you should regist the instance of class RMI_ServerLogic into the RMI Server as the line of "Naming.rebind("rmi://localhost/CalcService", a);" and you can change the port of this url such as "rmi://localhost:8933/CalcService" as you like.

RMI_Client.java : this is file is very simple. This file just contain the logic of calling the interface which is the server exposed in Main.java. If you have changed the port of RMI URL, you should change it in this file also.

Now let's compile these file:
step 1. Unrar this file in the attachment, for example the name of folder is :d:/RMI_App
step 2. cd d:/RMI_App/src
step 3. Compile the source of all java code
cd rmi_app (now you are in the folder of d:/RMI_App/src/rmi_app)
javac *.java (you may delete all the .class file at first)
step 4. cd .. (now you are in the folder of d:/RMI_App/src)
step 5. rmiregistry (now this window will hold on, you should open another window to go on you experiment)
step 6. open another dos command window, and cd the folder of this project accroading to the folder in step 1, you should:
cd d:/RMI_App
step 7. now you should start up the server as the command : java rmi_app/Main (and this will hold the command line, please open another window to run client)
step 8. now you just open the third command window, and cd the folder : cd d:/RMI_App/src
step 9. and you can run the client programm to see the result now: java rmi_app/RMI_Client
you can get the result of : 3
this is because of the result is come from the function calling remotly with RMI .
Ok That's all, if any question, please leave me message or call me some time.

your Yi.

You must have a car in the stat of Texs U.S, because of the area are wild there, every want to go a place should have a car, and if you want to wald there where you want to, it will take so long time and you will feel very hard to walk there.
The road in Texs is rich. It has so many hight way there, and so many cars runing on these road. Jone also meet a lot of new friend, one of these friends is called HanYang, Yang was come from Canand, his parent and sisters emigrate from China many years ago. He is now reading in Lamar University. Yang has a car which is the same type of Jone's. Yang like his car. and also like Jone's car. Xuan and Yeyin also go with them to shopping and joning some party. They have so many funny in their life there. Jone also tell some new story about her and her friends. It also mekes me happy.
In my opinion, Jone have changed so much. In that time when we are together, she is so restrictive, we just live in our world just between us two. We cannot jump out of the limitation in out mind. But now Jone is different with past. I am glad to see that. I think that Jone also enjoin her situation now.

The Year in Front Us

At the end of the year 2008, I have went back the city of GuangZhou I was been before I went broad. And also I go back Netease. It seems all the things returns the back as the day I leave. But something is different. That is I have been change so much.

Standing on the begining of 2009, I have many feeling in my heart. There is not only something about past which I have experienced but also fullfill with the hopeness of the next year. I have so many of wishes for the wholly new year. I hope all of the families will be at good healthy condition, and all of the yong people will achieve best target on their career they wished, all the old man can have betst mood every day.

[Diary] Bye 2008 and Hello 2009

2009-01-16T13:17:00.002+08:00

As time passed by, We have alread get into the year of 2009. That is a year fullfill with hope and expection. Standing on the gate of the fully new year, I have so much sentiment in my mind.

The Year Behind Us

In the departed year, It likes a dream, even a nightmare. All the things of my life have changed, and my opinion changed as well.

At the begining of the year of 2008, I went to Hunan that is the home town of Jone. That is a cold winter I think. Two days after I arrive there, Jone's grandmother has passed away. She is person who is the closest to her. I know that she must be very sad during that time. Older gone, newer will come. that is the rule of the nature. Everything will carry on.

A week after grandmother passed away, I leave Jone's hometown and go to Chengdu. I think that I have fullfill with extremely confidence that time. Because I will go abroad after a short time. My parents told me a lot of things. They both hope us can have a good future there. All right, I have broad after two weeks from Chengdu. I have a clear plan in my mind that is I will study english, and passed the entering exam. In the feture we can have a common job there, live as a common American.

The new life is exciting at the beging of arriving Texs. There is few people here. that is different from China. And also so many hight way, chemical plant, houses. After two month of the free life there, I also study english for two month. I have remember the words of the whole book. I have study so hard during that time.

I have made some new friends there, and they are all entreat us so friendly. Every week we go to the church which is in Lamar House, and study Bible. Because of we have different Weltanschauung in our mind. We also have hold different opinion of life. Sometimes we hold different opinion when we discuss the world of god. Now I can really feel that what is the major things they go after. They just want to get the peace in their mind something missing in our mind.

After half and two months I came to America, I was ill a worst ill in my life at present. At the begining of that illness, I just got fever. as time goes by, I found I have a serious headache. During that time, I cannot stand by that paintfull. Jone was very anxious about my health. We dare not tell our parents my situation of heathy. Jone bring me to the hospital three times. And the doctor pick-up my Cerebrospinal Fluid for two times. That is terrible experiance in my life I think. For three weeks curing, I recoverd a little of my health and confidence. During the three weeks of my curing, Jone gives me the biggest support, and she rebuild my confidence. I am very appreciat with her. If there is no her encourage, I cannot hole the line I think.And with this period of illness, It is hardening more than I think that she is the one in my life.

When I leave hospital after three weeks cure. We decided to go back to China. After three days break, We return to our country by air.

The Year in Front of Us

(To be continue...)

[Diary] Papa and Mum go back to Sichuan last week

2008-12-22T22:30:00.004+08:00

I have not be here for almost a week. Now I am alone in Guangzhou. Papa and Mum have went back to Sicuan now. They should return back to Sichuan because they have a lot thing to do with my uncle and auntie. My uncle and antie have a serious traffic accident a week before, and two of them are badly hurt in that accident, their car hit the guardrail badly. Uncle has broken three ribs, and one of his arm is broken also. Antie have broken her four ribs and her face have a wound as six centimetters long. That's terrible. Two of them are lie in the hospital for a week. They need someone to take care of them. Their daughter my sister need to face so cruel fact. I think that she must very afraid and heartrending. Hope everything goes better.
Today the temperature in Guangzhou has descend almost ten degree. I finally feel that the winter has come. Mum have already prepared for me a warm bedding. Every night I can sleep warmly. Thank you mum.

[Diary] I hurt you mum, I am so sorry

2008-12-10T22:17:00.002+08:00

I hurt you mum. I am so sorry, but I don't know how to say sorry to you directly. I am so sorry to say that words to you. I don't want to hurt her, that is not my originally meaning. I don't know what I should to do, How to tell her I am very sorry.
Tonight, Mum told me a lot about the how good is the apartment in guangzhou, and the apartment is so beautiful and it is so valuable to buy now, but I cannot make a decision to buy the apartment in guangzhou just because my wife not in GuangZhou, and she told me that I should be strong to make decision, espicially in the problem of apartment. I keep scilence when she told me that. Then she ask me why Jone want to go abroad to America, It cause our live so dreariness and if Jone work at Netease, she will have a good salary, and we can buy a big house. and our live will be very good different from what is like now. I think that she must ignore what is the satuation Jone have when she work in the company Netease. We do experiance all the paintfull life time, especially Jone. I know that Jone have endure so much than others in this family. When she is still working in the company Netease, the situation she has is very serious. Every night she will delay her sleep very late just because her sickness of the skin. The lump always appears on her skin go with the pruritus. We are all worry about the illness on her body. On the other hand, on her work, during that time, she has very heavy work, because there are just two man to keep one of the biggest product. Jone is the one of the tow. So hight pressure she was enduring.
When mum throw those word out, I feel it is so unfair to Jone. We didn't want to choose the way to go abroad, We have to. She have to go this way, because it is not allowed to stay in the place where Jone was on. Except we lost my life.
I am so regret that I throw these words to her. Because I feel that my attititude is so bad to her. That is the bumble I made tonight. I just don't know what should I do after that argument. I really want to say sorry to her, Mum I am so sorry...

[Diary] Something in my mind recently

2008-11-24T16:40:00.001+08:00

It is a special kind work of Developement, you need to concentrat with all the thing on that aspect. This will cause that you just forget all the thing outside the world of the Developing. I think that concentrate is the most important things in the work of mine. But I have a strange feeling that I cannot concentrate on one thing for long time, even if it is very interested to me. I don't know why it like that. It is very hard to me to concentrate with one thing now. Maybe that is because of I have not familiar with the job content which is more different before.I can study fast also like it is before. But I cannot use these knowledge agile. That is the problem in my work.

The day ended the first world war before 90 years

2008-11-11T19:14:00.006+08:00

Today I know that today is the anniversary the first world war ended. 90 years passed science the first world war ended we almost forget the most tragic disaster in human history. Here is some picture about that war:

This is a map of the first world war. It shows that the situation of the war.

This is the grave of all the soldiers dead in that war. There are more than 30,000,000 people dead in this war. civiliandead in Triple Entente are 20%, and soldiers occupy about 36%. Civilian dead in Ally occupy equal the soldiers as 22%. Most of the civilian dead from the Vaccinum Influenzae Vivum during the war time. This is one of the most biggest war in human history. And this is a big tragedy in human history. We should remember all about this, and let our children know How serious the war is if it happen.

[Reshipment] Speech of American President Obama

2008-11-11T13:27:00.003+08:00

Hello, Chicago!
If there is anyone out there who still doubts that America is a place where all things are possible; who still wonders if the dream of our founders is alive in our time; who still questions the power of our democracy, tonight is your answer.
It's the answer told by lines that stretched around schools and churches in numbers this nation has never seen; by people who waited three hours and four hours, many for the very first time in their lives, because they believed that this time must be different; that their voice could be that difference.
It's the answer spoken by young and old, rich and poor, Democrat and Republican, black, white, Latino, Asian, Native American, gay, straight, disabled and not disabled — Americans who sent a message to the world that we have never been a collection of red states and blue states; we are, and always will be, the United States of America.
It's the answer that led those who have been told for so long by so many to be cynical, and fearful, and doubtful of what we can achieve to put their hands on the arc of history and bend it once more toward the hope of a better day.
It's been a long time coming, but tonight, because of what we did on this day, in this election, at this defining moment, change has come to America.
I just received a very gracious call from Sen. McCain. He fought long and hard in this campaign, and he's fought even longer and harder for the country he loves. He has endured sacrifices for America that most of us cannot begin to imagine, and we are better off for the service rendered by this brave and selfless leader. I congratulate him and Gov. Palin for all they have achieved, and I look forward to working with them to renew this nation's promise in the months ahead.
I want to thank my partner in this journey, a man who campaigned from his heart and spoke for the men and women he grew up with on the streets of Scranton and rode with on that train home to Delaware, the vice-president-elect of the United States, Joe Biden.
I would not be standing here tonight without the unyielding support of my best friend for the last 16 years, the rock of our family and the love of my life, our nation's next first lady, Michelle Obama. Sasha and Malia, I love you both so much, and you have earned the new puppy that's coming with us to the White House. And while she's no longer with us, I know my grandmother is watching, along with the family that made me who I am. I miss them tonight, and know that my debt to them is beyond measure.
To my campaign manager, David Plouffe; my chief strategist, David Axelrod; and the best campaign team ever assembled in the history of politics — you made this happen, and I am forever grateful for what you've sacrificed to get it done.
But above all, I will never forget who this victory truly belongs to — it belongs to you.
I was never the likeliest candidate for this office. We didn't start with much money or many endorsements. Our campaign was not hatched in the halls of Washington — it began in the backyards of Des Moines and the living rooms of Concord and the front porches of Charleston.
It was built by working men and women who dug into what little savings they had to give $5 and $10 and $20 to this cause. It grew strength from the young people who rejected the myth of their generation's apathy; who left their homes and their families for jobs that offered little pay and less sleep; from the not-so-young people who braved the bitter cold and scorching heat to knock on the doors of perfect strangers; from the millions of Americans who volunteered and organized, and proved that more than two centuries later, a government of the people, by the people and for the people has not perished from this earth. This is your victory.
I know you didn't do this just to win an election, and I know you didn't do it for me. You did it because you understand the enormity of the task that lies ahead. For even as we celebrate tonight, we know the challenges that tomorrow will bring are the greatest of our lifetime — two wars, a planet in peril, the worst financial crisis in a century. Even as we stand here tonight, we know there are brave Americans waking up in the deserts of Iraq and the mountains of Afghanistan to risk their lives for us. There are mothers and fathers who will lie awake after their children fall asleep and wonder how they'll make the mortgage, or pay their doctor's bills, or save enough for college. There is new energy to harness and new jobs to be created; new schools to build and threats to meet and alliances to repair.
The road ahead will be long. Our climb will be steep. We may not get there in one year, or even one term, but America — I have never been more hopeful than I am tonight that we will get there. I promise you: We as a people will get there.
There will be setbacks and false starts. There are many who won't agree with every decision or policy I make as president, and we know that government can't solve every problem. But I will always be honest with you about the challenges we face. I will listen to you, especially when we disagree. And, above all, I will ask you join in the work of remaking this nation the only way it's been done in America for 221 years — block by block, brick by brick, callused hand by callused hand.
What began 21 months ago in the depths of winter must not end on this autumn night. This victory alone is not the change we seek — it is only the chance for us to make that change. And that cannot happen if we go back to the way things were. It cannot happen without you.
So let us summon a new spirit of patriotism; of service and responsibility where each of us resolves to pitch in and work harder and look after not only ourselves, but each other. Let us remember that if this financial crisis taught us anything, it's that we cannot have a thriving Wall Street while Main Street suffers. In this country, we rise or fall as one nation — as one people.
Let us resist the temptation to fall back on the same partisanship and pettiness and immaturity that has poisoned our politics for so long. Let us remember that it was a man from this state who first carried the banner of the Republican Party to the White House — a party founded on the values of self-reliance, individual liberty and national unity. Those are values we all share, and while the Democratic Party has won a great victory tonight, we do so with a measure of humility and determination to heal the divides that have held back our progress.
As Lincoln said to a nation far more divided than ours, "We are not enemies, but friends... Though passion may have strained, it must not break our bonds of affection." And, to those Americans whose support I have yet to earn, I may not have won your vote, but I hear your voices, I need your help, and I will be your president, too.
And to all those watching tonight from beyond our shores, from parliaments and palaces to those who are huddled around radios in the forgotten corners of our world — our stories are singular, but our destiny is shared, and a new dawn of American leadership is at hand. To those who would tear this world down: We will defeat you. To those who seek peace and security: We support you. And to all those who have wondered if America's beacon still burns as bright: Tonight, we proved once more that the true strength of our nation comes not from the might of our arms or the scale of our wealth, but from the enduring power of our ideals: democracy, liberty, opportunity and unyielding hope.
For that is the true genius of America — that America can change. Our union can be perfected. And what we have already achieved gives us hope for what we can and must achieve tomorrow.
This election had many firsts and many stories that will be told for generations. But one that's on my mind tonight is about a woman who cast her ballot in Atlanta. She's a lot like the millions of others who stood in line to make their voice heard in this election, except for one thing: Ann Nixon Cooper is 106 years old.
She was born just a generation past slavery; a time when there were no cars on the road or planes in the sky; when someone like her couldn't vote for two reasons — because she was a woman and because of the color of her skin.
And tonight, I think about all that she's seen throughout her century in America — the heartache and the hope; the struggle and the progress; the times we were told that we can't and the people who pressed on with that American creed: Yes, we can.
At a time when women's voices were silenced and their hopes dismissed, she lived to see them stand up and speak out and reach for the ballot. Yes, we can.
When there was despair in the Dust Bowl and depression across the land, she saw a nation conquer fear itself with a New Deal, new jobs and a new sense of common purpose. Yes, we can.
When the bombs fell on our harbor and tyranny threatened the world, she was there to witness a generation rise to greatness and a democracy was saved. Yes, we can.
She was there for the buses in Montgomery, the hoses in Birmingham, a bridge in Selma and a preacher from Atlanta who told a people that "We Shall Overcome." Yes, we can.
A man touched down on the moon, a wall came down in Berlin, a world was connected by our own science and imagination. And this year, in this election, she touched her finger to a screen and cast her vote, because after 106 years in America, through the best of times and the darkest of hours, she knows how America can change. Yes, we can.
America, we have come so far. We have seen so much. But there is so much more to do. So tonight, let us ask ourselves: If our children should live to see the next century; if my daughters should be so lucky to live as long as Ann Nixon Cooper, what change will they see? What progress will we have made?
This is our chance to answer that call. This is our moment. This is our time — to put our people back to work and open doors of opportunity for our kids; to restore prosperity and promote the cause of peace; to reclaim the American Dream and reaffirm that fundamental truth that out of many, we are one; that while we breathe, we hope, and where we are met with cynicism, and doubt, and those who tell us that we can't, we will respond with that timeless creed that sums up the spirit of a people: Yes, we can.
Thank you, God bless you, and may God bless the United States of America.

[Diary] Nightmare yesterday night

2008-11-09T01:39:00.004+08:00

It is 2 o'clock morning. I just wanna to tell all of you that I just have a nightmare right now.

It began in a town where just like the town at the Jone's home town. I found that we are going to go somewhere. We are in a bus station waiting for the right bus to go. You know the people of this country are so many people, especially in the bus station and in the railway station. This time, We are in a bus station at Jone’s hometown. I found that so many people are peasantry. They have so many luggages, the big one and small one. And people there are so many that we cannot stand stably.

We have two tickets for two seat that bus. When we get into that bus ,we found that there are almost no place to stand. It has been taken by others our seats. I am very sad at that time. So we get off that bus and found the boss of the boss of that passenger train company. I told him very angry. I complain that there is so many people in that bus, it will cause accident to overload. Another one is someone has occupied our seat, but there is no one to stop it. The order here is fuck-up too bad.

The boss of that bus station apologizes to us, and promises to find another bus for us. We think that it sounds not bad. So I am quiet down. By one hour’s waiting, a bus came into the station. And large crowds of people move near the bus. I told Jone that I need to occupy two seat for us. You just wait at the same place, and look after the luggage. With saying these words, I put myself into the crowds of people. Through tem minutes effort, finally I get into the bus and occupy two seat with putting a small luggage in that seat. I found the bus fulfill with people so rapidly. When I want to tell Jone to get into the bus from the window, I cannot see her at that place where she stands. It let me so vexation. Where did she go? Only thing I can do is to wait. Wait for her appearance again. I told the driver my wife has not get into the bus, and just wait a moment.

People go on to get into the bus. It becomes crowd soon. It becomes crowd my hart also. Suddenly, the seat for Jone jut occupied with a small luggage are seat with a woman in middle-age, and the luggage on that seat not is under the bottom of that woman. I am very angry about that. So I bark out to her very rudely: hey, that my seat you should not to seat there. But that woman seems do not hear the words what I say. I go on to shout at her. But she is still no action to me. It causes me so angry that I stand up and walk to her. I said that it is my wife’s seat you should not to occupied it, and I have put a luggage on that seat, don’t you see it? It likes a wood that woman. She pretends to hear nothing what I am saying. I am angry at that time. And hold her collar and put those words on her face. The woman is very scared. Then she withdraws her bottom to another place.

This must be a little victory to me. I still can not be happy, because I missed my wife Jone. Where did she go? I just set in that bus anxiety. The bus will under its way, but Jone is still not here, I cannot see her, but I cannot give up the two seats. What can I do?

At that time I just wake up suddenly. I just lie on my bed lonely. I found that it is a dream. My wife Jone is not besides me. She is in another side of the earth. Maybe that is because I miss her and worry about her live in America.

[Diary] Meeting for a new game engine

2008-10-31T12:11:00.000+08:00

Sorry to forgot writing diary yesterday
I have attend a meeting yesterday afternoon when off duty. This is a meeting about a new game engine written by Cloudy wu.I hear about that cloudy wu have spend two years for that.
The meeting is an introduction meeting of that game engine. Cloudy wu is in Hangzhou and we communicate with him by a telephone and computer desktop share. We can see the desktop of Cloudy wu's desktop in the local computer. We put the image signal into projective. Many of the team member attend this meeting, we sit in the meeting room watching the image output from the projective and listen to sound made by the telephone.
The engine is a fully new one. That composed with Server and Client. With this engine, Server can communicate with client by the method(function) of RPC(Remote procedure call), that seems to call the local method(function) apparently. In fact, this is a remote information developer and call the remove function. This engine designed as no return valued. So it is a single direction call. Through this method of calling, Game server and client can communicate with each other freely.
Another aspect of this engine is to maintenance all the process running on the server. This engine use an form as multi-process. So when on-line game are running, server program will have many process to deal with the logic. So it becomes complex, many of the data need to transfer between process. It will spend a lot in a computer for transfer the data between processes. But it has excellence itself, designer can divide different logic into different process(But the two cannot have complex communication with each other). These different processes need can dispatch to different server. So with this engine you can easily build a distribution construct on-line-game server.
The more detail information of this engine. I have not so clear. Now Cloud wu and his team are developing an new game useing this engine.We should wait for the demo of this game. Then we can understand the engine more.

[Technologe] Engine Flow in the Game development (2)

2008-10-29T19:53:00.000+08:00

Engine use the libevent to manage all the socket message from all the client. This reduce amount of the work. Today I study the composition of the library of libevent. And at this time I found an introduction of this tools in Chinese, I reship it into my blog own. If interest with it, please go to http://blog.163.com/gordenfl to read about it.
Back now! The libevent are a library to deal with all the event happen in three aspect in the computer programming, Network transportation(I/O Buffer), DNS resolution(Asynchronous), Event-driven HTTP server. In the application of the three aspect, we need to have attention with the Network transportation. In this par of the library, they bring a new principle to manage all the asynchronous event during the program with the according to the different protocol such as HTTP, DNS, and other protocol defined by programmer.

We know about the TCP/IP protocol is a base protocol for HTTP DNS and so on. We use TCP/IP for all the On-line Game development. We use this protocol to communication between client and server.

Next we will talk about the most important part of the online game server engine, the Event Loop.

[Technology] Call Lua in C/C++ program

2008-10-29T19:35:00.000+08:00

lua_istable(gL, -1) whether the top of the stack is a table type element. The parameter of -1 is the meaning of top element of the stack.

lua_isfunction(gL, -1) whether the top element of the stack is a function, the number -1 is point to the top element of the stack.

lua_getglobal(gL, "kick_user") Find the function named as "kick_user" in the global area.

lua_pushstring(gL, "gorden") this will push a string object into the stack. Sometime it is used to push a string into stack as a parameter for the follow function call.

lua_getref(gL, refobj) this will push an ref object into the stack. Sometime it is used to push an object into stack as a parameter for follow function call.

lua_pcall(gL, 2, 0, 0) it will call the function of the function just found. You should push the parameter into stack before this function be called.
The second parameter is means that how many of the parameters in this call of function.
The third of the parameter is told the function that how many the result are. If you set the parameter as "LUA_MULTRET" you can get the multi-result, these results will push back into the stack according to the normal order. So if you want fetch these result, you first fetch the last one of them.
The fourth of the parameter is a function pointer, it means that the index of the error process function on the stack. If error occur, the function will be called by system automatic.
To recognize the function call between lua and C, you can see the article written by Cloud Wu from here:http://blog.codingnow.com/2006/01/_lua.html

[Technologe] Engine Flow in the Game development (1)

2008-10-28T12:26:00.001+08:00

An on-line game always composite with Client and Server. We will focus on the Server part of the on-line game. This passage will told us what composite the on-line game server. And why it is like that. And we will discuss about the calling between script and daemon program.

Ok Let's go.

We all know about that the on-line game player use a client to connect to server with TCP/IP protocol. They control the client fairy, the client program will do its logic code, and send package to server. When server received the package, it will calculate all the data with the logic on the server. Then server will send the result back to the client. After that client will draw the result onto the screen when it receive the result package.

In this process, all the people will connect to the server, server will receive all the client's package. On server, there is an array to reserve all the connection(all the client's connection). Sever program (in short of Server) have a big loop in itself; every loop it will deal with all the package from all the client. At the end of the loop, server will receive the package push into the queue of the message for next loop.

Firstly, Server need to start up. When it starting, server need to do several things: To initial server daemon, asign signal catch function, create log file description handler, create server socket, then waiting for the message comes from client.

When client connect to the server, server will response for that connection, create a new socket to communication with it, and this socket will insert into an queue which is fill with all the connection socket. Commonly, socket are bind with other information as a struct. The queue with type of this struct are the main data struct when server is running.
The socket are nonblock. because this will be more efficient and effective than blok mode. There are heart beat in the server daemon.

[Diary] We saved our bicycle

2008-10-24T18:35:00.000+08:00

Two bicycle which we have in two years ago saved by my mum and me today. This afternoon my mum and me go to WenChangYuan where Jone and me lived for one years. When I am coming back Guangzhou , my Dad told me that these two bicycles need to be got back. This time when mum come here in Guangzhou, We decide to get the tow bike back to the park near where we live.

We arrive WenChangYuan at 5:00pm this afternoon. We found the two bicycles stand in a corner in the park of WenChangYuan. There is so many dust on these two bicycles. We almost cann't recognize whether they are our bike. With removing the dust on these bike, we can see straight they are the bikes we have in the past. I took two picture for them:

It looks so dirty that I cannot believe these bike is ours. Mum and me begin to clean all the dust on the bike. After 10 minutes, The two become clean. At that time I just believer that is our bikes. After cleaned it, We found that the bike were broken by somebody, maybe some children.
The tyres of the two bike have shriveled, there are no air in the tyres. And one of the footplate of the big bike were missed. We need to mend it right now.
After cleaning the two guy, I have found that the big bike is locked by the lock. The key of the lock are missed long times ago. So I can only hold the bike and walk to the maintain place. Mum

push the other one. We found a maintain place to prepare the bike.
One hour passed, the two guy's condition become better so we can ride on them. We took them back to the place we live. Now they are locked in the stair well.

[Diary] Fantasy in my mind

2008-10-23T19:54:00.000+08:00

Fantasy are always around me, it lasts for two month already. I always want to have clear understanding what it is in my mind. But it is pity, I lost my memory when I want to recall what is in my mind when it happend. I still remember that the first time it appeared. It was when I still ill in America. I have got ill. In the rest of time, the condition of my memory is not very good. Representing as lost memory, difficult to concentrate, low of the emotion I found all of that are always accompany with me all the time. I cann't concentrate with the other things. Maybe I need time to recover and to change the worse satuation.
I still remember that Mark told me the story of his family when I am in Beaumont every week. I feel that is a family fullfill with happiness and hope. I hope someday I can have these. That is the goal of my life. Maybe after I have this goal I will never miss in the life. So now I need to do my best to get rid of the illness in my mind, and let me to become more happy during my life.
I know that I can do it, I can do it.

[Diary] Mam's coming Guangzhou

Today, I received a call from Dad. He told me that mum is coming to GuangZhou. Now she must in the train. She bring two luggage. And she will arrive Guangzhou after one day. Tuesday morning I will receive her in the train station.

[Diary] In the past when we are together

2008-10-18T15:25:00.000+08:00

Hi dear Jone,
This is a letter I write for you over the past and old experiance.
I just go to the place we had been to. I just like the feeling of to miss you when I see these place and buildings.
In trust-mart, I stop my feet in the front of the goods shelf selling phones. I remember the time when we buy the phones together for our dad and mum. It was a very little thing for us in that time, but now it is so valuable in our memory.
Oh dear, things are different now in GuangZhou. The trees beside the street are stronger than before. People in the street are much than we imagine. Stay at home, I can see the balcony of juanjuan's house. And in the HuangPu Street, still have so many vehicles on that road make out big noise. People in the industrial garden are much more than it has before. Many of the new company are move here.
So many things in GuangZhou are still the same as before. I have been to Haiyin Bridge, the things around it has few change. these place called the old GuangZhou. Stand on the people's bridge I can feel the breezee and semall the flavour of GuangZhou. The river is still flow day and night. But people are not here beside me. In that breezee, I really miss you!

Hi dear, how are you now? what is the situation there? Can you tell me about that? Hoping you can return back beside me. That's the biggest wish in my mind.

Yi Liu From GuangZhou

In the last post, I told about the story of a dog that is saved by oneqiong and me. So long time passed, I couldn't forget the dog yet. We have our own dog called "XiaoHuang", it have so many habit we gives to it. Now "XiaoHuang" is still live in the home in Hunan. it lives with the parent of oneqiong. it have so good condition to live. we can set our mind at rest, because our parent can take care of the dog very careful.
I still want to introduce "XiaoHuang" to you. These photos are toke in GuangZhou when it is very young.

I took this picture when I bring it to an animal hospital. Because of caching a code, xiaohuang need to cure this ill. This photo shows that xiaohuang are reciving the cure.

When xiaohuang is older, we took it out. The dog like to go out of my apartment, it love the nature very much. The flower, the tree, and the child are the best thin in its mind.
It love to cling to someting. The oneqiong's hand is approaching its' head, xiaohuang is cling to this hand. Look! what a laze boy it is.

When xiaohuang is bring to Hunan, he can go out and go to much place, because of the wildly spaces they have. Also xiaohuang become a big guy then.

Look! what a handsome dog it is. Haaaaaha! And Oneqiong looks like a little girl. It is very interesting.

Now XiaoHuang is not beside me. I really miss it. I just want to stroke its' fur, and look at its' eyes. To tell xiaohuang just "we love you"!

[Diary] I am back Guangzhou now

2008-10-16T19:59:00.000+08:00

I have come back to Guangzhou for 1 week now. I have finished so many things these days. I have lived in a apartment by lease, and bought some nesserary necessary living goods. Because of the recruiting in campus, all the workmate in the human resource department went out. They were all busy with this task.
I have three days for free. I went to many place where we always went to my wife and me. Also I toke many pictures when I went there.

These pictures are the restaurant called "XuLiuShan", in the main commerce center Tianhe regional GuangZhou. You can have some delicious dessert in this restaurant. Ofcause, Oneqiong like these kinds of dessert best. When she is in Guangzhou, she always goes to there and have some soft drink.

And I also went to the ZhuJiang river. On the big bridge on the river, I toke some photoes below:

This bridge is called "HaiYin Bridge". Oneqiong and me always walk on this bridge when we work in Guangzhou. But now juse me walk there. I really fell a little lonely.

"Xiaolian" is a dog that we found in a trash near by the Glaxy Computer Market. I still remember that Oneqiong and me found that dog.

One day we passby the Glaxy computer market, we heard dog's groan. We feel the a dog is hurt very serious. We found it in a rubbish bucket. The Dog is so weak that it almost can't sound out. I put the dog into a plastic pocket and take it back. We found that the dog is ill, then we took the dog to the veterinary doctor gives the dog cure. But finanly we cannot save the dog. At the end of its life we gives it a name called "Xiaolian". That name means that a pitty guy.

Today I am back to the place where we first meet the pitty guy the rubbish bucket, and I toke photo of that rubbish.

We still yearn the little dog.

[Diary] lonely days in GuangZhou

2008-10-14T23:16:00.000+08:00

I have been in GuangZhou for 5 days. There is just endless waiting here for me. Waitting for the answer of the company, it looks like everyone in the company are very busy. I know that now everyon in the human resource department are busy to find next generation freshman. Yes, it is very important to development of the company.

GuangZhou is the same as before when I leave here. I feel a little strange when I came back here. I don't know why I have this feeling. Maybe somebody and something were different. But I have so strong feeling that this city is the one I loved. My wife told me that she love this city before we went overseas. I have this feeling until coming back from America.

These days, I went many place where we have been in. Haizhu Square, The Commercial Street in BeiJing Road, The side of ZhuJiang River, So many place that evoke old memories of me and my wife. It seems most valuable to us tow. I eat what we have eaten in the past, And it cause me to recall so many things before, Let me so sentimental.

Maybe I should face to the feature on my road. For her better life outside, and the better life of my family. This is the power of my life and whole family.

Welcome to my blog in English

2008-10-13T21:30:00.000+08:00

Hello everyone! Welcome to my blog in English. To improve my english, I decide to write blog in english here. I am a programmer in Online Games. And I have graduated from university for 4 years now. I love english very much and I will go on study english forever.

Some friend of my wife told me that English is very important for everyone in this social today. And I also feel that it is very important to me when I return back from the Unite State. My wife also told me that english can improve the ability of communication, and She always force me to study english in the pass. Now I finally understant what dose she think about that.

I also be told to study english in the middle school and college time. My father told me that, and my friend sam also told me about that, but I cannot understand the mean in deed. What a pity man I was.

So I create this blog to practice my written english and I will also practice the spoken english in ordinary times. When I walk in the street myself, I can speak some english to myself. And I can attent some meeting with some foreign friend. So I really very miss the time when I am in America. Mark, Juli, Grage, Debra and other foreign friends are give me very improvement in my speaking english. I will thank for them all.
