A man named SID, fanatically hobbies, saves and organizes photos. SID's wife named Debbie, they have three sons logan, archie and chuck. He has a big house, with a male tube home Simon and a maid PAM. I will introduce his family, his house and his hobby: shoot, collect and show off his photos.

Now, SID lives happily - family, friends and holidays. He took photos from time to time. In fact, he always with a camera with you. He doesn't want to miss anything. Every breakfast, lunch and dinner will be taken. When the children go home from the school, the camera is ingested to their father's greetings. When the children are doing homework, "snap, snoring, snoring", the camera's shutter is not stopped. On the baseball match, every throw of the son Archie was taken. At the school's dance, Chuck's father took every slow dance step and the conversation next to the soda machine. His dog - Sadie is the most taking the most of the number of times in the world.

He and his family have collected several million photos. Some photos were destroyed, and some have experienced changes. SID has a magical system to handle these photos. Let me tell you about how his family, his house, and how his family is committed to developing, organizing and protecting all of these photos.

SID is taken with a special camera. Every camera is taken at the same time, it produces a photo and a film. He never uses a film (this is a science fiction technology). The photo was attached to the wall of the room, while the film was saved in a safe place.

1.1.1 SID home

I introduced the SID home? Ok. It is very big and everywhere is a photo. Because photos are too much, SID must be looking for places to place them. Some photos are hung on the wall, some are hidden in the photo book, some inserted into the scrapbook, and some will never be an eye in a box placed in the storage room. All of these photos are placed somewhere in his home. He called these places to place photos as "photo space". A photo space may be a room with a lot of walls, or have a multi-page scrapbook. A room is a photo logical storage unit. The wall in the room is the physical structure of the photo space saved.

1.1. 2 Debbie's housework

Because SID is busy shooting and handling photos, he does not have enough energy to place and store them - that is her wife's work. The full name of Debbie is Debra Wrider. Her T-shirt is printed with DBWR - this is a family tradition - tag for all things.

It is a huge job to place all of these photos well, but SID and DEBBIE have established a system. When the SID shooting is over, he puts the photos on a specific shelf in the kitchen. That specific shelf is called "db_buffer_cache". Debbie often checks the shelf and see if there is a new photo. In the day, she placed the photos from the shelf on the corresponding photo space. In fact, in a baseball match or school dance party, the speed of SID is too fast. So that Debbie can't keep up. This is a special scenario, SID takes a photo, then placed on that particular shelf, DEBBIE puts these photos in the scrapbook, hung on the wall or inserted into the camera.

When the SID enters the kitchen with a photo and the film, he and his wife may have such a conversation:

SID: "Dear, guess me to bring you back?"

DEBBIE: "You took a lot of photos, is you? Do you know how much I like to organize a photo."

SID: "Of course, Archie's baseball team won the last game. He won two two-two-twoth base in the ninth game, I all filled it."

Debbie: "Too good, those photos are placed in the sports class of the film space No. 9 wall, it seems to be great. I can't wait to place them, I will invite all the neighbors to watch."

SID: "Archie is also very happy. OK, I will take some photos, I will come back after 23 milliseconds. Oh, by the way, I just put those photos on the db_buffer_cache shelf. Now SID directory number is 1332935. "Debbie:" I know, goodbye. "

In order to easily manage photos, frameworks, and logs, he uses a special number to create a directory, called SID directory number. He uses these unique, increasing numbers to track all photos of all photos in this house. SID and DEBBIE have been tired of the directory number of the view SID. SID writes "SID directory numbers" on all photos, tapes and negatives, and is tired to cramp. Finally, they scandard "SID's directory number" is SCN. Remember SCN, SID's life around it.

Now, all families know that this number is referred to as SCN. You can see SCN in every place. The SID writes them on the film and then writes the low and high SCN outside each pack. Debbie writes them in place where she is placed. These numbers are especially important in the complex family life of SID.

Debbie puts photos in the frame, each frame in the house is as large. Some frames only saved a photo, some of the frames saved a few photos. Some particularly large photos will occupy multiple frames. The SID has a photo of the same size, shooting him in the air after skydiving, this photo occupies two frames. When the photo spans the frame, the SID is called a photo chain.

At any time, as long as Debbie changes the photo within the frame, she writes the SCN of the photo on the frame. Each photo in the house has a unique number. They call this number of the photo as a photo ID. These photo ID helps the photos on all walls in the SID management. If he needs to find a photo as soon as possible, he is implemented by photo ID. Through the photo ID, the SID can quickly find the wall and save the photo frame.

Sometimes, the SID will change some of the photos. If he wants to edit a photo, then he lets Debbie find his photo through photo ID. Debbie gives him a copy of the entire frame of the required photo. In order to prevent the SID may change the idea, do not like some changes he has already done, he put the copy in a storage room, called "Retreat" storage room. When the SID has completed the change and determined, Debbie put the changed photo back into the original place and writing the new SCN on the frame. If the SID doesn't like his changes, they take the frame from the "Rollback" storage room and put it back on the wall. In this way, the photo is not called before the SID.

1.1.3 Logan's housework

In order to handle the photos of the SID, DEBBIE has been busy, so she does not have enough time and energy to handle the SID film. Sid believes that his son wasted too much time on playing video games and eating potatoes, and he decided to arrange mission.

The sid of the sid is called Logan William Randolph. LGWR is printed on the logan shirt. Logan has a very simple but very important task. The SID camera generates a photo, which produces the film, and the logan task is to put the film in the notebook. There is another shelf in the kitchen in the home, and the SID is labeled to mark the negatives that send to the big son. The label is called "log_buffer", Logan is sitting next to the kitchen desk, observing this special log_buffer shelf. When a film is placed on this shelf, he immediately put the film in the notebook. SID said that these notebooks are "redo notebooks". He used this name because he can re-create a photo in the back of the inside. Logan Checking the frequency of his shelf is much higher than Debbie. SID said that as long as there is a film, he can re-create a photo at any time. Logan and his father's dialogue is short and warm:

SID: "Logan, the film is on the shelf!" Logan: "I know, I will handle it immediately."

Logan places these negatives in the order of the film to "redo notebook". Once the current notebook is filled with the film, he will change another new notebook. Every time he replaces the "redirect notebook", he is a record on the "Alarm Notebook", then informs his brothers to carry out their housework.

Sorrow, is it? Dad and his big son are too focused on the film!

Incidentally, not all photos have corresponding negatives save. SID specifies that some photos do not have to be logged, these photos do not have the corresponding negatives to save in "redo notebook". SID said it is "no log".

1.1.4 ARCHIE family

The second son Archibald of the SID is another task. His shirt writes Arch. Archie places them in a safe place from the back of the notebook.

When Archie found that logan replaced to another, he began to act. He picked up those negatives in the notebook, put them in a safe place outside the house. The SID has built a genus in the backyard. That is the safe place he saved the film. If the storm comes, it destroys the house, he can use the film stored in the basement to replace those damaged photos. Each logan's "redo notebook" copy, known as "archiving redo notebook".

Maybe one day, you can hear the smile between SID and his second:

SID :: "Archie? Where are you?"

Archie: "Dad, I am in my own room, is logan to switch the notebook now?"

SID: "Yes, he just finished."

Archie: "Know, Dad. I will copy these negatives and make a new notebook in the basement. Then I will update the 'Control notebook', and write a record in the 'alarm notebook'."

SID: "You are a good child, I know you can believe you."

1.1.5 Chuck's housework

SID Minimal Son Chuck makes everything is synchronized. His full name is Charles Kenneth Patrick Thomas. The letters on his shirt are CKPT. The task of Chuck is to coordinate each wall, phased book, and photo numbers on the scrapbook and digital to control the numbers in the notebook. When he got the signal, he began to run in the house, write a number on each wall, while the same number is also recorded in the control notebook. This makes everything coordinated. The following is a SID and CHUCK dialogue:

SID: "Hi, Chuck."

Chuck: "Dad, Logan starts to replace the notebook?"

SID: "Yes, son, you know the rules. Running the room with the directory number 1332935, write this number to each wall, each scrapbook cover and photo box top."

Chuck: "No problem, give me a few microseconds".

SID: "Don't forget to write 1332935 on the control notebook!"

Chuck: "Dad, I know, the same thing I have done hundreds of times in the day."

I dare to bet, you have been tired of reading this crazy SID home, is it? So far, you may have seen the SID has a functional disorder. Functional disorder? Yes it is! However, it is effective and reliable. SID likes this.

1.1.6 Control Notebook

How do this family maintain all these activities? SID, DEBBIE, LOGAN, Archie and Chuck are concluded, and if you want to collect and organize this photo, you must make a lot of detailed notes. Each of them writes his own things to a log called "Control Notebook". Control the notebook has a list of home property list that records each wall, scrapbook, and photo boxes throughout the house. If the SID adds a room to place more photos, he makes a record in the control notebook. When logan replaces the notebook, he is summoned in the control notebook. Every time Archie makes an archived redo notebook to put into the basement, he writes the name and SCN in the control notebook. Every time Chuck runs a circle in the house, he also records the details in the control notebook. This special notebook dynamically saves the asset status of all places, and the process represented by the house.

1.1.7 alarm log

There is always a little unexpected event, or there may be an error. Debbie may have problems when the photo is placed in the frame, because there is no extra space on the wall. Archie may not fold the bottom slicker, because some people spray the soda water above. SID took into account all possible, he bought a spiral axis, put it in the kitchen drawer. Write "Alarm Log" on the face of the notebook. Every family member will encounter the problem in this log. They not only have to record the mistakes, but also to write down the normal activity process. This alarm log is a convenience where you are used to save things that are already in SID. If they want to explain the extra details in a certain situation, they make a new "tracking notebook" and record the information inside. In this way, this alarm notebook will not become more messy than it is originally like.

1.1.8 Early Morning Procedure

The whole family wakes up together, and always goes to bed at the same time. They call these time for a day "start" and "close". Below is the morning startup program:

SID started from the bed, and a cup of coffee started his day. On the side of the coffee maker, he saved a series of instructions in the notebook, called the initialization parameter file. Read this command to help him start a new day. Sir, he walked over and confirmed whether the notebook was placed in the old place. He went to the house wake Debbie, Chuck, Logan, Archie, Simon and Pamela (you will encounter them soon).

When everyone wakes up, open the control notebook. Confirm according to the content of the control notebook, all the photos walls have no problem, when all things have been checked, he opened the house to welcome guests and start taking photos. SID hired a male tube home, Simon, helped him in the morning, Simon's tuxedo wrote the letter Smon (one letter in the name). Some mornings are particularly messy, because every member of the family does not clean up their respective things in a timely sleep time. When SIMON is in place, SID opens the curtain, hangs a phone, open the door lock, his family is open, ready to welcome guests. SID and SIMON may start this day:

Simon: "Good morning, sir. I can help you today?"

SID: "Yes Simon, good morning. It seems that we are very messy here. We suddenly interrupted last night. Can you handle all these no completed photos and 'back'."

Simon: "Of course, all these negatives must be re-made in the back of the notebook, and then placed in the correct frame in a simple order."

SID: "After you have finished these, then handle the 'backlifting', is it?"

Simon: "Of course, Mr.. I take the photo frame from the retreat storage room, then put the old version back to the original place."

SID: "Great, after you finish, I will open the house." 1.1.9 Night Program

The night time of the SID family is also very interesting. When the SID is lying down, he asks all things in the home to put, turn off and stop. The first action in bed time is to ask all the guests in the house to go home. There are four situations in the evening of the SID. The first, sometimes he is very resistant, waiting for all the male and female guests to leave, then sleep; second, SID has no resistance, he personally supervises every guest, when guests have finished their own things (see photos, etc. After waiting), he gave guests to the direction of the door; the third, the SID did not have tolerance, he got with them to accompany them, do not let them finish doing things; the fourth, SID pulls down the house of the house, The big call "time", a wolf in the house. Simon had to clean up the chaotic scene next morning.

When a guest left a mess, SID called his maid Pamelamonica. She monitors the activities of the guests and the treatment is dealing with the good. Her cleaning equipment is labeled PMON.

If the SID does not suddenly pull the gate, everyone opens the light and cleans it. Synchronous processing the notebook to complete your own tasks. Debbie takes away all the photos from the DB_Buffer_Cache shelf, put it on the appropriate wall. Logan

The Log_Buffer shelf is empty, all the negatives are in the current recurrent notebook. Chuck is a circle in the house, with the highest and lowest directory number (SCN) to update the walls and notebooks. Archie put the final film into the archived redo notebook and put it on the basement of the backyard. Then update the control and alarm notebook. When everyone is finished, the SID turcks the lights, and everyone is sleeping.

1.1.10 SID problem

Sometimes, SID is a problem. When any of these events occur, the activity in the house will stop.

· When the SID woke up, he could not find the initialization file, it could not start the day of work.

Sometimes, SID needs to save the backyard basement with Archie to restore the lost photo, if he lost a negative, or after the backsheet is destroyed during the recovery process. He can't recover any after that the invalid negative film

All photos.

· SID lost a few negatives at a time. He accidentally opened the camera and exposed the film. This makes him feel very bad, and his world seems to have come to the end. He contacted the camera manufacturer and they provided a special camera with two film compartments. In this way, in case the film is destroyed, he can also count on the film in another compartment. The SID is called a mirror.

· If the basement of the backyard is full, Archie has no space to place a new negative. Archie is just waiting for new space in the basement. This makes SID and DEBBIE followed, and the entire SID family activity is in a pause state.

· If DEBBIE has a flu, he is sick in bed. You guess how you will see: SID is madly close the door. Although these problems and other family setbacks and functional disorders, SID family can still handle millions of photos and thousands of guests visit.

Like me, you may want to know how SID will have so much time and energy to make photo collection activities. Does he have no job? In fact, no. Money is not the target of the SID. He doesn't have to work. He completed a smart investment a few years ago. He bought a large number of computer companies in 1984, then they just released to the public. He invested in the red tree coast of California.
