I have a problem in PHP.When more than one client update something in database, they won't work.so, how do I make out for it?example:at the same time, in real-time chatboard, 2 persons click CHAT, what can I do so that both of them actually chat?or at bidding website, when 2 persons bid at same time, how could I do that?thanks for answer.

When we login, we got a session.But at the same time when we still login, another one could login at our account.So, can we restrict only one user could login at one account?So if another wants to log into the same account, he must wait until the one logs out.Thanks in advance.

I'm trying to use mail() function.What I have to do beforehand?I have XAMPP installed, is Mercury one of mail servers?If so, what I could do to use it?

I made this code to test isometric projection: #include <graphics.h>#include <stdlib.h>#include <stdio.h>#include <conio.h>#include <math.h>float matrix[4][4] ={{1, 0, 0, 0}, {0, 0, 0, 0}, {0, 0, 1, 0}, {0, 0, 0, 1}};void vertex( float x, float y, float z ){ float n[4],r[4]={0, 0, 0, 0}; n[0]=x; n[1]=y; n[2]=z; n[3]=1; for(int i=0; i<4; i++) for(int j=0; j<4; j++) r[i]+=n[j]*matrix[j][i]; putpixel(r[0]+(getmaxx()/2),r[1]+(getmaxx()/2),YELLOW);}int main(void){ int gdriver = DETECT, gmode, errorcode; initgraph(&gdriver, &gmode, ""); errorcode = graphresult(); if (errorcode != grOk) { printf("Graphics error: %s\n", grapherrormsg(errorcode)); printf("Press any key to halt:"); getch(); exit(1); } int angle = 40; do{ cleardevice(); //isometric projection matrix[2][0] = -0.5 * sin( angle * M_PI / 180 ); matrix[2][1] = -0.5 * cos( angle * M_PI / 180 ); for(int i=-100; i< 100; i+=1) for(int j=-100; j< 100; j+=1) vertex(i,0,j); angle+=10; if(angle>=360) angle=0; }while(!kbhit()); getch(); closegraph(); return 0;} this code is for isometric projection, can anyone help me to turn it to perspective projection?or maybe ones called that Mode7.

so, how can I make RSS reader on my website? thanks in advance

After the annual event of Tokyo Game Show 2007, SquareEnix released the 'closed megatheater' for the new Kingdom Hearts titles. And for you who loved consoles or even PCs, this could be not a good news. However, if you had one of PSP or even NDS, then this news is a great news for you and me (I owned NDS by the way). The new Kingdom Hearts titles were released in PSP (Portable Sony Playstation) with the name of Kingdom Hearts: Birth by Sleep. At the moment before TGS'07 I've ever watched a trailer of Kingdom Hearts, and that was when the news of Kingdom Hearts 3 were issued (even until now no official news of Kingdom Hearts 3 were exist). The secret trailers were for this new Kingdom Hearts : Birth by Sleep. After Sora, Kairi and Riku were back at Destiny Island, everything come to a good ending. That's when SquareEnix told us that Birth by Sleep happened in the past, for certain 10 years in the past, before the first Kingdom Hearts. The story followed that one man known as Keyblade Master named Xehanort was dangerous, and another Keyblade Master sent three of his students Terra, Aqua, and Vent to stop whatever Xehanort done. The trailer showed us a scene somewhere inside the game itself, the battle between Terra, Vent, and Aqua fought the follower of Xehanort, ended in defeat of the three. The graphics were stunning, really I had thought this was for nex-gen consoles, but turned out only an FMV for PSP. The gameplay sounds nice, where we could have three different stories for Vent, Terra, and Aqua in their pursuit. I've been trying to have a trailer for the gameplay, but I couldn't, only still images I found. The next one is for ones who didn't have PSP at the moment. This is Kingdom Hearts who had somewhat unique (or weird) name, Kingdom Hearts: 358/2 Days released for DS (Nintendo Dual-Screen). For the trailer I haven't found any of them, but from the info I had, this game based on the days Roxas had within Organization XIII, the days where Sora was sleeping from the event of Kingdom Hearts: Chain of Memories in Oblivion Castle. Other than info for the speculation of the name coming from, which is we could use more than 1 player (yes, multiplayer so we could use Axel also), I have no other information of this game. I wonder when BlueLaguna.net or khinsider.com will share the new informations about this game... Well, for the gameplay, some said it is slight different than usual Kingdom Hearts and we could hope for the new usage for the stylus for DS. They better had more usage than just pointing (like in Final Fantasy III). Lastly, well so many of the fans were not very satisfied for the last of three new Kingdom Hearts, which released for handphone, which (maybe) only covered the whole Japan region only (like Final Fantasy XIII: Agito). This is Kingdom Hearts: Coded, where we played as Jimminy Cricket. I haven't heard about the story other than King Mickey told Jimmy to search for the lost pages of his diary... and the new battle system named Coded itself. So, there they are, the three new Kingdom Hearts title that I've found out at the moment. When I had new information (release date I presume) I'll share again.

As a software laboratory assistant, I teach the class of Object Oriented Programming. Everything went well until one day a student of mine ask me a simple problem like this Q/A: him : Why must we use Object oriented Programming? I thought the usual one could do almost everything. me : Well, in Object Oriented Programming we could make a class, so basically eveything could be made to an 'object' in our mind. him : That's why I'm asking, why must we made everything an object? What's the difference? me : In Object Oriented Programming, Encapsulation is the basic part and because of that concept, we could make an object with parameters / data and methods / functions in just one object / class. him : Are you saying the programming will be simpler? me : Not really, but in our mind it is far easier when the class is made up and we just use the object freely in our program. (okay, that's the intro, now the things I couldn't explain...) him : Just in case I made the program in usual (not OOP), what's the difference? me : well, you can hide the data in data hiding concept of encapsulation. him : We hide data from our own selves as programmers, if we didn't let the user do something the data won't be shown and we don't need to hide any data. me : I guess... that's how we put it... hmm, in OOP we could use spesific methods related to spesific class I think. him : Instead of using like ball.animate() why don't we use animate(ball) (ball in struct)? It is easier right? me : But, to make animate() for several class inhereted from one, we can use similar name. him : Just use if... just like this void animate(struct ball ball) { if(ball.type==1) animate1() else if(ball.type==2) animate2(); } we could do it right?? me : ... So I couldn't say anything to him, only to promise him to answer next time I teach them next Tuesday... I've questioned the same ones to my friends but none of them can help. Please someone help me...

Right now I'm still in my way to finish .hack//GU episode 3. Well, at first (before episode 1, when I saw the trailer movie) I'm really longed to play this game because personally I really loved .hack//Saga from .hack//SIGN and all the 4 part of .hack//Infection till Quarrantine.However though, I'm not really satisfied with .hack//GU's way to deliver scenes (and I mean in-game scenes). I really like how the new cell-shading techniques for the FMV (Full-Motion Video) but the in-game scenes were just... too plain. So many scenes of the game only show characters from .hack//GU stand in somewhat-vast room / area, then the camera will go move around them...I guess the lack comes from the camera itself and the vastness of the area they were. Most of the area seems too big just for them, not like how the events came out in the anime. (just so you know, .hack//GU first hour of gameplay is also available at the anime .hack//ROOTS the later episodes).hack//GU character Haseo's growth to be the Player Killer Killer is shown well in .hack//ROOTS but, somehow in the game when he was deleveled to 1, his personality is somewhat... not really what I expect I guess. For the 2 episodes sequels from .hack//GU episode 1, CC Corporation could make a good epic advanture even though I guess the first 4 games were somewhat better in how they deliver the story. From what I got, I could say that storyline in .hack//GU is far more complicated than the first 4 .hack// games. But, this game couldn't make me understand that from how they deliver the story itself.

So, that's in Bulgaria huh? Here in my country we always had the latest videogames available (even I don't like piracy myself but I guess because of console game piracy I could play all my games though...). That's why most people know my country is a heaven for videogame players (but hell for videogame developers...) I had a friend moved to America (California to be precise) several years ago, and he kinda envied me because I could play Dinasty Warrior 5 at the moment the game was released while at the same time he bought a legal copy of Dinasty Warrior 4 (wait until the game's price drop). So, for me to buy/not a game is not really a problem, not like people in America/Japan who must save up a set of time just to buy a videogame.

English-languaged RPG Maker XP comes in 3 forms, a first edition which still have dll in Japanese and have various bugs, the second edition called Postality Knights (anyone can tell me why they made this name???) and the latest is the legal English-RPG Maker that I had installed in my comp. (though I use cracked version) The greatest achievement is RPGMaker XP could have various battle system (compared to the predesessor that so many RPG-maker games have similar battle system), but becuase the legal is out, I rarely see the free games available (not like RPG-Maker 2000 that have abundant number of free games in various sites).

You said an RPG, so I should say I would like to see the complex class / job system. And also, we as public gamers may feel the generic class / jobs are just... too plain. I took one of the examples, in Matrix Online everyone is not just like swordsman, mage, or any like them. We need some skils that are new to us, maybe in Matrix Online one can crack the path, or if one condition met, they could so something special or just like that. I also want to see graphics even though I don't see too much graphics (like in BattleOn) can give better fun, because some regions of the world may see wait too long loading means to quit playing your game. Graphics are good, but don't be too much for them. For storyline, I expect something more than just people wandering in a world than do nothing other than monster-slaying (like many browser-RPG). I expect just like in true MMORPG we could have more interraction with history that runs through the game, I mean in the game itself the story is updated in set of moments, so we could see something new more and more. I don't think for online game need for complex storyline, but storyline itself is needed.

yeah. even so many people throughout the worlds said this is one of greates Final Fantasy ever made or so ever, but for me, from Final Fantasy VII to Final Fantasy XII, I guess the twelveth game is the big failure when they try to migrate to action-intended RPG. face it, Square Enix (or should I say Squaresoft) is not a suitable developer for Action-gameplay games. The Bouncer, Final Fantasy: Dirge of Cerberus, and some more I forgot are not great game (despite the very cool graphics compared to others) but they are not good in developing the gameplay. so, FFXII is a bridge for SquareEnix to implementing action-gameplay to their masterpiece genre, RPG. (yeah, Brave fencer Musashi and Kingdom Hearts are great games thought...) but in the end, they made the worst battle system ever (from FFVII to FFXII). The animation is poor (despite the summoned beings) and the magic attacks seems so poorly made (I can't see my fireball not like the previous Final Fantasy..) and the worst of all, I can't stand to wait for seconds just to attack while you can move around so freely... well, when I saw Final FAntasy XIII trailers, I could be sure that FFXII is just a guinea pig or should be a bridge between Final Fantasy X (Individual Speed Turn Battle System) to a fully action-but-not-action-RPG like, just like the trailer shown me. and so, this is the only modern Final Fantasy that I didn't finished... (I'm fortunate not to buy, but borrow from my friend...)
