                     Chapter 1: What??

 
 “Ten more minutes!” my dad said as I walked into the public library. By the way, my name is Eric. I had published a book and I was searching for it. I searched frantically for the label HE or the ISBN 976-1-861-72144-8. I was mezzo (moderately) exasperated. At Dad’s two-minute warning, I was already seeing clumps of H’s. “Umm… HA, HU, HJ, HI, GW?” I whispered as I searched. There! Supercalifragilisticexpialidocious! I found the book I was looking for! The book was called The Computer Thief.
        I excitedly opened the book’s cover to read my masterpiece. Suddenly, wind gushed in from the north. “That’s unusual!” I said. “The trees outside aren’t even moving an inch!” But, then a branch flew through the window and I got really dizzy and sleepy just like if I were hypnotized! I felt like I was going to barf when I opened my eyes. The feeling disappeared completely, as well as the library. I was in a huge building, as far as I could see, and it appeared that my dad was in a chair doing stuff on the big desktop computer. It did not look normal to me what he was doing. Normally, he would be coding something in Microsoft Visual Studio 2010 or checking his Outlook or Gmail inbox. But, as far as I could see, there were only points, arrows, lines and a mysterious ‘toolbox’ on the top of the screen. I had a weird feeling inside my mind. It was creepy but anxious and excited. It meant that something was wrong.
        I stepped an inch or two closer. Now, I could see some very familiar shapes…They were MOSFET (Metal-Oxide Semiconductor Field-Effect Transistor) transistors! Just in case you didn’t know, a transistor is the teeny switching component used in all digital devices (including phones, remote controlled vehicles (RCV’s), computers, and a calculator is a smaller example) and most radios. I was thinking about what happened when Dad started to WHISTLE, which really distracts me a lot. Not only did he whistle, but he whistled at the precise eardrum-busting, super-loud, and ultra-high pitched note, which I think is a high G or something. Then I noticed a little logo at the bottom. At first, I just saw a blurry mess and a ® sign at the top-right corner. But as I stepped closer, the blue image got clearer and clearer and more and more familiar. Once I was about a foot away from the screen, I recognized it.
        It was the Intel Corporation logo! Now I wondered “Why would I be sent to an abstract Intel® world?” But, I remembered how the quantum entangler in the first book had set me into a haunted house, which was really creepy. There was a trap that dropped you into a pit of zombies! Anyway, let’s stay on-topic. Then I realized that entanglement could have happened or it was a magic book…Shut up, myself! I don’t believe in magic! Well, I was in an alternate world, thanks to quantum entanglement. Yeah, well I traveled into this future 4-dimensional frame, according to these formulae:
·         is the formula used to calculate volume of a 4-dimensional object.
·         is the formula used for replacing matter.
There was probably a replacement by quantum entanglement going on, which means that an atom in this exact spot would reference an atom in this exact spot maybe three million, eight hundred twenty nine thousand, six hundred thirty one frames or four-dimensional frames ahead of the ‘normal’ world. Maybe the stuff in the book got read by some sort of quantum thingy…Anyways, I went up to Dad and said “Hi, Dad!” He responded “Hi, Eric. When I got here, I knew we were in trouble because a guy shoved me into this office and made me design CPU’s (Central Processing Units). Can you help me make a circuit that adds two bits of a binary number plus a carry input?  Thanks!” ”Sure,” I said. The result was a special 8-transistor ‘full adder’ (computer adding device). Luckily, he was carrying his laptop with him when the teleportation phenomenon happened, so the laptop went along with him. Too bad I wasn’t carrying the book when I teleported, because I wanted to read. Well, if I did, maybe I would teleport to even another four dimensional frame. Anyway, I started to mess around on the laptop computer Dad brought. It had an Intel® Core® i5 vPro in it. I figured it could outwit a Pentium 3 by far means. I started scribbling something in Paint that was a closed shape then filled in some of the spots left from the scribble. The shading worked for every closed shape, even if the lines are interconnecting. So, I made this huge scribble and tried it. Oops! That didn’t work. It filled the whole drawing space with black! Seems like I forgot to end the line where it started! So, I undid that and drew my current ‘end’ to the beginning. There! Once it was filled, it created a very familiar painting…The well-famed portrait of Picasso…in black and white! There were blocks of hair, eyes, and face. It almost seemed like that the plain grayscale would change into a rainbow of abstract colors. There were not too many colors, though. 
 
                 

                     Chapter 2: Not So Cool


        Dad said that he had to go to a very important meeting. I insisted that I come with him. He said okay but only this time. So, I went out of his office with him. Once we got to the meeting room, which was Room 1032, a worker was working with something that looked like rows and rows of long, tall cabinets with wires sticking out of them. It looked very familiar, like it was in a picture. Anyway, there were handfuls of people coming into the room at once! I did not even know if they were this many people in the entire worldwide Intel Corporation! So far, there are…let me count…1,534, no, 1676, no again, 1783 though I only estimated 1,503. Wow! On my way in, a sign said ‘MAXIMUM OCCUPANCY: 3,566’, so the room was more than halfway full already! The room was as big as an oversized auditorium! The room was like the movie theater when Cloudy with a Chance of Meatballs 2 came out!
        I thought that everyone had already settled when this worker ran into the room like an oversized baseball player, huffing and puffing all the way home. No one that I knew of ran like that, except for Hannah Bitar, who was in my third grade class, and Alex, who is in the fifth grade. They both run like chickens. “Marko! YOU ARE LATE FOR THE FIFTH TIME TO A VERY, VERY, IMPORTANT MEETING! WHAT’S GOING ON?!” the head worker shouted at Marko. Poor Marko just sat down in the last row all by himself. This time he would have been on time if he did not have a bathroom emergency at the last second!
        “Today I will be showing you the latest innovation in technology,” the lead worker said. “Here,” he said as he pointed to the rows and rows of cabinets, “is the traditional supercomputer. It has a hundred thousand Intel® Core® i7 Extreme processors (they are the latest in the Core® series) in it.” “And here,” he continued, “Is the microchip equivalent of that,” he said as he held up a computer chip smaller than his palm. Everyone gawked at it. Some even whispered that it was fake. The lead worker heard most of the whispers, so he decided to show everyone that it was a real, functioning, Central Processing Unit. So, he took apart a computer, removed the current chip, and then replaced it with the new one. He put everything back together. Then, he said “Calm down! This is no wireless or Bluetooth joke! There is clearly no wireless connections in here! This actual chip processes information on its own -> !” So, he booted up the one with the chip in it first and inputted Console.Write (diff (math. pi * square (new Randm ())). ToString());. As you can see, he spelled Random wrong. In return, the computer displayed ERROR: randm does not have a constructor that takes 0 arguments ERROR: Class randm is undefined. The worker’s face turned purple, then white, then as red as a fully ripe apple. Close to everyone laughed maniacally at him! I even heard someone call him as ‘Mr. Color-Changing Iguana’!
The worker calmed down and said, “I will time this computer anyway, so here it goes!” He typed the line correctly this time and added a timing function to it. He hit F5 (run button). Almost instantly, a result popped up on the screen. It said 0.64490439437949039320317097316432063140 for the result of the calculation and 40u for the time. Next, he shut down the smaller computer and turned on the big supercomputer. He timed it on the same calculation. It displayed 0.6649043943794 9039320317097316432063140 and 14.2m for the time. The ‘audience’ gawked at the difference between the times. For a regular home computer, it would take almost 1,420 seconds to complete the calculation. That means to complete it in one second, there would have to be 1,420 home computers linked up to complete the calculation. This chip sure is the great CPU innovation of the last three decades! The lead worker explained that this had transistors paired up with each other in an atomic scale and that there were one hundred thousand and one ‘floors’, one for each processor plus an additional level to sort out the wiring. All of the sides of the processing unit were full of connector buses and supporting components. He claimed that this processor could withstand 534° Celsius. Sheesh! With THAT many processors all cramped and crushed together, it is more like 217° Fahrenheit! He explained that making things smaller would help because then the electricity would travel faster through the wires. Ugh! Seriously? Light and electricity travel at a speed of five million meters per second! It would only make a few picoseconds (one millionth of a millionth of a second) of a difference! Nevertheless, I think that the thing that made it so fast is extra processors and/or wireless communication between the processors.
        He kept on talking about things like a new architecture and to end the Core® series, and blah, blah, blah. I almost fell asleep for the rest of the meeting. It seemed to me like more of a daylong without-a-break rambling presentation rather than a short, one-hour meeting because, one, the worker was not good at grammar, so he used a lot of long, rambling sentences with lots and lots of BORING details and two, nobody else got to talk. I was almost fully asleep when Dad said that it was over. Whew! I thought that I would be stuck in the room hearing very boring words for the rest of my life.
We went back to the office. It was 7:13 PM already so we went out of the office yet again and into the elevator. Once we got to the first floor, we walked outside and luckily hailed a taxi. Dad asked the driver to drive us to the nearest hotel. Either the hotel was pretty far, or that I perceived time wrong, because the drive felt like one thousand, six hundred and twenty miles to me. I almost fell asleep yet AGAIN in the, I think, on mile five hundred though I never saw daylight in the entire drive. Finally, we got to the hotel. It was a Marriot’s, though it looked more like an apartment than a hotel. It was pretty much thirty-one stories tall, but the width was only about five small-sized hotel rooms. I spotted a suspicious-looking large room on the third floor. I calculated that the volume was around seven hundred and fifty small hotel rooms. I guess Phoenix has many visitors and will probably face a population boom (also called a rapid growth of population) in the next few decades. Anyway, we went in the door. Inside, the light yellow was the walls painted and there was a granite check-in counter on a dark oak stand. When my dad was checking in, I grabbed a few donut-shaped peppermints from a small bowl on the left side of the round counter.
I tasted one. Yum! That was the best peppermint in the world in the whole wide universe! Because they tasted so good, I spent the next five minutes stuffing thousands of them in my mouth. That is, until Dad noticed. “ERIC! WHAT ARE YOU DOING?” he yelled right into my ear, giving me such a sudden shock that My mouth opened completely and all of those super yummy peppermints spilled out of my mouth and landed on the floor. Yuck! After I cleaned up the mess that I made, Dad said that our room was 0333, which meant third floor, third row, and third column. We rushed into the last elevator with its door open. Whew!
Once we got to the third floor, we went to our room. It turned out that our room was the ‘mysterious large room’ I spotted on our way in! Just how lucky can this be? I am pretty sure is a one-of-a-kind room! Once we were all settled down, we peeked at this room. It had a living room, a master room, a bathroom with an advanced Delta® showerhead in the tub, and even an extra bedroom! Dad said that with enough negotiation, or talking back, he only had to pay ninety-five dollars a week for a room this big instead of the regular $235.99 a week. Turns out that Dad promised to give them an advanced version of the new Intel® superprocessor if they reduced it to fifth price. I do not know why, but they accepted. They must be people who are computer lovers or people with very slow computers that have Pentium® I processors (Pentium processors are the oldest Intel® official CPU’s available). Those who put us in this room might have been a coincidence, because maybe $95 is the lowest price they could get to without being screamed at or potentially fired. Dad said that he needed to go use the computer. I followed him. He booted up the laptop I was using in his office and logged in. He immediately opened up Notepad and began to type XML code. He wanted to upload a picture called 11 (which is of the front of the hotel) to Facebook but accidentally uploaded a picture called 12 (which is of the chip). Here is his code:
美国四年级娃写的“挨踢”小小说


As you can see, his error is bolded out for you. You do not have to read anything else in the code. He did not check his code and put it straight in the Java compiler (also called XML translator) so the computer could understand the XML, which in the beginning is just a bunch of text with an ‘.xml’ file extension. I was about to tell Dad that there was an error when he ran the program.
        Aww! Come on! “Of course C:\Users\lancehe\ Pictures\SeperateWorld\12 is not right!” I told Dad. “Whoops,” he said as he went back to change his code. “Too late!” I interrupted. “The file has already been posted! What are you doing NOW?” I continued. “Aww, SHOOT!” He said. ”This is a top secret project! Now I am going to be fired forever! I kind of felt sorry for him so I said “Maybe I can help you out of this mess,” “How can you help me?” he asked. “We will see how I could help you. All that matters is whose hands this data gets into. If it gets into the wrong hands, Intel’s dead and I might not have the ability to help you.
        It was 9:36 in the night, so it was time to go to bed. We showered and dried off. Then, Dad went into the master room to sleep and I went in the extra bedroom. Wow! The mattress had extra soft memory foam! This is what I call QUALITY! I started snoozing right away. 
 
          

                      Chapter 3: Normal Day
       

 

          I had a nightmare about me being in the Intel building with Dad, then an earthquake happened, and I woke up when I was just inches from splattering on the ground in my dream to realize that I was still in the hotel. Dad was trying to wake me up by yelling that it was time to get up and pounding my back. When I got fully dressed, it was already 8:40 in the morning. It did not look like 8:40 in the morning because the sun had just came above the eastern horizon. The sun was bright anyways, so you would think that it would be ten o’clock in the morning if you looked straight above you at the sky. I heard an airplane rumbling above. I thought that it was a private jet because it was just so small compared to those huge Boeing 747 jumbo jets I have seen before. On the other hand, it might have been a jet-powered hang glider. I do not see why someone would ride a HANG GLIDER up that high because it is so darn cold up there, though. It was traveling very slow compared to other slow planes I have spotted before.
        You know, how sometimes you have to wait HOURS to see a taxi pass by you. In addition, not always will you able to hail them. That is exactly what happened today. We had to wait approximately 2 hours for even one taxi to pass by and another hour for us to hail successfully a taxi. We told the driver to drive us to Intel Corporation. This drive somehow felt shorter than the drive last night, maybe because of the fact that I was probably very sleepy yesterday. On our way, I expected to see desert, but I saw lush green forests.
        At Intel®, it was a regular day. There were  people swarming everywhere to get everywhere, from Room 2628 to Room 1017. Though after 11:00 AM sharp, almost nobody even set foot in the halls with the exception for meetings. This time, I messed around with Microsoft Visio 2013 and made plumbing pipe and electromechanical diagrams. I even discovered that I had made a plumbing system fit for a house! There were so many pipes and valves and other things like sprinklers and even toilets! Yeah, I said toilets!
        Speaking of TOILETS, I had a stomachache and I had to stay inside the restroom for an HOUR straight. A crazy dude even tried to crawl in! By the end of that, my entire butt was numb by far means. Once I found my way back to Dad’s office, and by the way it is Room 2032, I could not believe how much progress he had made wiring the transistors. Maybe he used the little blue ‘Auto route’ button that was shaped like a road at the bottom of the screen where there is the rotate, flip, and save buttons a lot. As far as I could tell, there were a few thousand transistors already. He was done with a fourth of the ALU (Arithmetical Logic Unit). 
I also helped him a bit. He couldn’t make a binary subtractor (digital subtracting device) smaller than 800 nano meters. I knew that a single misplaced wire could make the processing unit short-circuit or fail to perform a very simple task, like adding two 1-bit binary numbers. Though, I remind him very often that he needs to check because I know him by heart. Remember he didn’t when he used the XML (eXtensible Markup Language)? So, I helped him make the subtractor.  There was a very tight fit that might not work, so Dad e-mailed an architectural designer and said “Hello. This is Lance. Can you make even smaller transistors?” “Sure. We have some 20 square nanometer designs! I’ll be there in a sec. Bye!”
        The designer came into the room. “Are you Lance?” he asked as he pointed at Dad. “Yes, I am the one who asked you for smaller transistors over the phone” Dad replied. “Do you want CMOS (Complementary Metal Oxide Semiconductor) type or TTL (Transistor-Transistor Logic) type?” the designer continued. “How about the CMOS type?” Dad asked. So, the designer pulled out a flash drive from his pocket and downloaded the ‘n20n.mos and the p20n.mos’ files to the designer application. It took about forty-five minutes for those darn files to upload completely! I thought that the computer needed to upload every teeny proton, neutron, and electron! Though the designer said that many other applications were running in the background, I didn’t believe him until he opened the Task Manager. That was slow too. But once it opened, the text was unbelievable. It said:  ‘Number of Running Applications: 543: Critical’, which meant that the computer was about to crash!
        The hum of Dad’s computer was not a hum anymore. It had become a deafening roar. I guess a nearby worker heard our abnormally loud computer, because he came rushing through the door, ended all processes on the computer, waved a finger at Dad, and quickly left the office like a cheetah running at full speed. Dad just sat there in shock, with his mouth like a large, wide, and round O in the font Wide Latin! I think the worker that came in was a bit too offensive or he didn’t have enough time to calmly talk to Dad about ending the processes that Dad didn’t need to work and that he was about to blow up the processor, which is going to cost HIM extra expense of $851.99. Yup! Extra with a capital E! That’s why he shut down all the processes. Plus, he didn’t save Dad’s work, so he would have to re-wire hundreds of transistors all over again! Dad sighed and went back to work.
        The rest of the day went like yesterday, though no random Picasso portraits, no big meetings about innovations on processors, and no stomachache. In other words, there was nothing out of the ordinary for the rest of the day. What a peaceful day. I sat at Dad’s laptop and started messing around with Microsoft Word macros. Then, somehow, I opened Microsoft Visual Basic for Applications. Visual Basic coding is very weird. There are DIFFERENT block types like Function, If, Sub, and so on. It was definitely not like any other computer programming language I knew of, including C#, JavaScript, and other object-oriented programming languages.
        Enough with the advanced tech talk. What I said about ‘programming languages’ meant that Visual Basic was drastically different than other ‘ways’ of computer coding. I had to fiddle around with it for forty-five minutes just to figure out the syntax (It’s a bit like grammar in human languages) of VB. Once I figured that out, I went diving into the Classes. A class is a thing that has many variables and functions inside of it. Shoot! I could not access a custom class because the default class type was an abstract, which meant that you cannot access it because it had many different types you could define it as! I was very frustrated.
      But, soon enough, it was dinnertime at five o’clock. Since there was a cafeteria at our hotel, we decided to go back. This time, we were smarter and rode Bus 375 to the fifth stop then transferred onto Bus 128 to go to the hotel. Once we arrived, we went up the elevator to the second floor. The cafeteria had all sorts of food, from burgers to chicken nuggets. You didn’t have to pay for anything because the fee is included in you hotel fee. So, I got a platter of chicken nuggets with some ketchup in an additional teeny bowl with creative artistic designs of what looked like a bird with a very long tail on it.
      My god! The chicken nuggets tasted like heavenly heaven! Why does EVERYTHING taste awesome here, at Marriot’s? I thought that all of my friends complained about Marriot’s quality and location. After dinner, we went up to our room. And Dad was working at the computer again. He was replying an email. He told me to draw something and he gave he a pencil and twelve sheets of paper.
 

 

            Chapter 4: Huge Problem, Young Hero

 


      Meanwhile, a criminal hacker was in his home in Chicago, sitting on his automatic seat that warms itself depending on his body temperature. A day earlier, he had seen Dad’s image on Facebook and came up with a plan: To destroy all of the super chip’s (.chip) files on the designer’s computer. ”There shouldn’t be any problems,” said the hacker joyfully. “It’s a perfect plan! I will get in my teleporter and get there in ten minutes!” So, he started packing the things he needed. “Hmm…What’s this? Oh. Ahh! Here it is! Here is my Ultimate Hacker’s Kit.” Also called the UHK, the Ultimate Hacker’s Kit provides every part a hacker needs at a low price of just $123 from Hackers United Incorporated. It is available to hackers all around the world. For example, a happy hacker in England got the kit for just £73.82! Soon, he was all packed up and ready to go.
      He stepped into the teleporter with all his belongings he needed. Then, he put the special 64HCA21153A02302P Analog Switch EEPROM (Electrically Erasable Programmable Read-Only Memory) chip in the special socket and pressed the ‘GO!’ button which in turn made the machine start warming up. His machine warmed up much faster than mine because he could afford four lasers and accelerator crystals so the Higgs field could manipulate exponentially…Enough with the science talk! Anyways, he was at Intel in no time!
      When he just set foot on Intel’s front door, I was ready to take a shower and go to bed. It was nine o’clock in the night already. So, I went in the bathroom and turned the valve to the red WARM label. Brrr! It was ICE-COLD! Because of that, I brushed my teeth first and then felt the water. IT WAS ICE-COLD AGAIN!! So, we went to the front desk via the emergency stairs and said that our shower heater did NOT work. They said that they would be sending a plumber up there in an hour. We went back up to our room via stairs again and began to do what we were doing before the strange shower incident.
      Meanwhile, the hacker already turned on his anti-magnetizer and stormed into the halls of the building. The security cameras’ relays went clicking off when he came within range of the cameras. Clicklicklicklick! He was a former worker at Intel Corporation but got fired because he kept on playing practical jokes and pranks on the other workers, so he knew the place by heart. He knew where the main designer’s office was. Then, somebody caught him. The person just jumped out of the dark right in front of the hacker. The hacker was used to things like this: the element of surprise, so he just calmly dumped a bucket of sand on the person. The person came out coughing like crazy. The hacker waited for any further reactions, but all that came out of the person was coughing and a few words: “You (cough) anene (cough) cephalous (cough) dude!” “Hey, this guy has pnuemonoultramicroscopicsilicovolcanoconiosis (a lung disease caused by the inhalation of very fine silica dust)!” Just as a note, the hacker loves super long words like that. “Can’t you (cough) even see (cough) that I am (cough) hippopotomonstrosesquippedalio… (Hippopotomonstrosesquippedaliophobia is the fear of long words)Eek!” said the person. The hacker held up and invisible phone in his hand and pretended to dial 9-1-1. “Hello? This guy needs an assococarnisanguineoviscericartilaginonervomeddularist (doctor)!” he said jokingly. But, he still saw no reaction so he moved on.
      He knew the room number of the main designer’s office was 1126 and it was on the twenty-fifth floor, which only included six offices and a stretching room. “This is a piece of cake,” he said to himself as he rode the elevator up to the 25th floor. And it was. He got into the right office in just two minutes. Luckily most of everybody left at eight o’clock in the night. “Supercalifragilisticexpialidocious!” he exclaimed quietly to himself. “Now, because the password is your room number followed by ‘@Intel’, I can easily hack into this designer’s account!” So, he turned on the computer and booted it up.
      It seemed like hours before the plumber even got notified of our bathroom incident! Even though I was drawing electronic circuits and simulating them in my head, which is one of my favorite activities, I was approximately equal to ‘bored to death’.  When the plumber came, I let out a sigh of relief, but knowing that I had to wait for ANOTHER hour for him to finish fixing it. Though that was my belief, the plumber, who came out in five minutes, said that the labels were supposed to be the other way around and he said to turn it to ‘Cold’ for hot water. Finally, a warm, relaxing shower…
      By then, the hacker had already signed in and was trying to delete the files. A little box popped up on the screen and said ‘Discovered 6819 items (12.82 GB)’ and after a few seconds it said ‘Deleting items:  1 hour 30 minutes remaining’. The hacker just impatiently waited there, humming the song called Daylight by the band called Maroon 5. Of course, the remaining time, if you plotted it, would be a curve down. So, the more till the end, the more the rate the time goes down at. That is one suggestion I have for the operating system Windows. I don’t know if it is true for Mac or Linux, but at least for Windows. So when the hacker saw ‘Ten minutes remaining’, he was delighted. Then, it went like ‘Nine minutes remaining’, ‘Seven minutes remaining’, ‘Four minutes remaining’, then ‘1 second remaining’. At last, the hacker moved the files to the Recycle Bin. What he didn’t know is that they are still in a place called Recycle Bin, and you can easily restore the items. He triumphantly shut down the computer and walked out of the room.
      In the next morning, I woke up with a little yawn. Dad was already wide awake. I didn’t have any dreams I remembered at all, though I was pretty sure I had at least five short minute-long dreams. Dad insisted that we skip breakfast again. I responded with a yes. I wanted to use Microsoft Visio again on the laptop. So, we rode the bus again. The total fare was five dollars! Speaking of money, Dad and I were lucky that this four dimensional frame still had Dad’s Chase bank account or else we would have been homeless! Hmm…a homeless Intel worker?
      Once Dad and I got to work, I did what I thought, which was more of Microsoft Visio. I made a schematic that lets you control 80 LED’s (Light Emitting Diodes) in a ten by eight grid with just 18 digital inputs! The technique is called ‘multiplexing’, which means there is one wire for each row and also one for each column. Then, I added a bunch of other circuitry like DACs, ADCs, counters, and of course, transistors. But I ran into a problem which is how to control brightness. After a few minutes, I figured out how to determine the brightness:  if the LEDs’ negative terminals are pointing to the column selectors, which is true in this case.
      We were about to leave for lunch when a crazy worker came in and started YELLING “WHERE ARE MY CPU FILES? WHERE ARE THEY?” My dad just ignored him. I said “I will help. What is wrong?” The worker smirked. I think he thought that kids could not help adults. “How?” the worker asked. “Have you searched8 for the files in your hard disk yet?” I asked. “No, and let me try it” he said as he rushed back to his office. After a few minutes, he came back to Dad’s office and said “I didn’t find it,” he said. “Now what?” he asked. “Maybe it is in your Recycle Bin. If it is not, probably you can process those ‘.temp’ files that are stored in the AppData folder.” I suggested. “Alright! That is a pretty good idea!” he said as he rushed out of the room. At his computer, the worker began by trying to go into the Recycle Bin, but access was denied somehow, maybe because the Recycle Bin was in Local Disk Q:\. So, he opened the program ‘temp File Converter’ and browsed and browsed until he found the files. He pressed the ‘Convert!’ button and it saved the converted files to a new folder on the desktop. “Success!” he said triumphantly.
      That night, news had spread about me saving their most advanced CPU. I got congratulatory comments and pats on the back. The designer got promoted to CEO because of ‘his ability to trust young children at an age of nine’ and I got promoted to ‘Analog Designer’ because of ‘my excellence in understanding very complex technology then using it to save the company’. But, then somebody yelled from behind “Designer! We need your help! A electrolytic capacitor in one of the robots blew up and is causing ten microprocessors to malfunction! Come quickly!
