Julie would never have gotten caught if she had thought about the system backups. And I never would have done anything about it if she hadn't lied to me about messing with my machine.
I work for Julie's father, or I should say I am a one-fourth partner with her father in a candle factory. We specialize in "hand dipped" candles. Actually it is only the outer two or three layers of colored wax that are hand dipped. The rest are dipped in huge batches by a machine which I invented. We supply these "hand dipped cores" to a wide variety of small candle companies throughout the United States and Canada.
To understand what Julie did, you have to understand the machine. Basically it "hand-dips" candles about 500 at a time. The machine consists of 3 large tubes, about 3 feet in diameter and about 8 feet tall. One tube has water at 130 degrees. One tube has water at 45 degrees. And the other tube has a special wax formula (also developed by me) at 135 degrees. There is a frame that fits inside each tube, that when properly strung holds 480 candle wicks that have been "pre- seeded" with a small amount of wax like a very thin candle. The candle frames attach to an adjustable, segmented center column and are built up layer by layer until they are about 6 feet tall. The whole assembly hangs by two large steel bars from square platform at the end of a specialized hydraulic boom. The round bottom platform is a heavy steel grid. On the upper, square platform there is a hydraulic shaker motor that can be adjusted to vibrate the whole assembly at almost any speed or intensity.
When the machine is operating, it quickly lowers the candles into the 130 degree water to preheat them. As it rises out of the water, a vibrator motor shakes the frame to help the water drip off. Then the candles are plunged into the wax and the vibrator motor kicks on again for just a few seconds to force off any air bubbles or water. The candles are drawn slowly up out of the wax and then plunged into the cold water to set that wax layer. This is repeated about 20 times to form a small candle and up to 50 or even 100 times to form a really large candle.
Julie is a college student and lives in a loft apartment in the factory. She is also the boss' daughter. Julie doesn't work during the week, but over the weekend, it is her responsibility to clean the equipment and cycle it through its maintenance and calibration runs.
I knew she was doing more than that. I didn't know what she was up to, but the cycle counters on the various actions were getting out of sync with the automated production logs recorded on the computer controls. There was no real problem with this, but it is my design and my machine and it bugged me that something was happening that didn't make sense. So, I asked Julie if she was doing anything with my machine over the weekend that wasn't on the schedules.
I really didn't expect her to tell me what she was doing, but I thought she would at least say she was sorry and wouldn't do it any more. Instead, she told me that it wasn't my machine, it was her father's and that she didn't have to listen so some technician obsess about numbers on a little dial. Then she said, "It is probably just an error in your control programs, anyway."
That really pissed me off. I designed and coded the machines and the software that ran them. I was pretty sure of my program. It had to be something else. But no program is foolproof. So before I really let loose on her, I decided I would recheck the logs against the meters on the machines.
The duty cycles on the water vats and candle vat were again out synch to the log. I double checked the the backups which ran every day except Sunday at 6:00 am and 6:00 pm. Looking through a couple of months of log files I finally noticed it - not in the log, but in the directory of log files on the hard drive. The files for Saturday night and Monday Morning were exactly the same file.
There shouldn't even be a Monday morning backup because my program backed up only files that had changed, any cycling of the machine for cleaning and calibration during the day on Saturday would change the log file, and so it would be backed up on Saturday night. But the production log file that had been backed up on Saturday night was also backed up on Monday morning. The files were identical down the size and date stamp. That could only happen if someone copied off the log file before the backup on Saturday night and overwrote the system log file with that copy before the backup on Monday morning. Julie was doing something on Saturday night or Sunday and hiding it by erasing the machine's production logs.
I had to find out what it was, so I modified the backup program to make a backup every hour over the weekend. What I found out was very interesting. Julie had created her own production program, but it didn't make any sense. The candle frame was set to randomly plunge into either the 45 degree or 130 degree water, and the vibration motor was also set to come on randomly for anywhere from one to 20 minutes. The whole production routine was set to run from 6:30 on Saturday night until a maximum of noon on Sunday. The duty cycle wasn't over stressing my machine. From what I could tell, it might sit totally still for up to a couple of hours and then cycle through repeated vibrations or plunging into the water baths. I really had no idea the purpose of Julie's programing, so I set up several hidden surveillance cameras in the production area. The video feed went to the same computer in my office that held the system backups. From there it went out on a secure internet feed to my home computer.
What I watched the next Saturday night was, to say the least, surprising and stimulating. After Julie had cleaned the machine, she disassembled and cleaned all of the candle frames. Then she reassembled all but one of the frames. Nothing happened after that until just before the 6:00 pm backup. At that time she came down from her apartment totally naked and carrying a large gym bag. She must have just showered or perhaps rubbed herself down with oil because the security lights reflected off her body and made it look almost like she was glowing.
After she set the gym bag down next to the frame, she walked over to the control council and plugged in a memory card. I assume she was copying off the production log file and loading her special programs. She stood before the control council for a few moments until the screen indicated that the production log was backed up. Then she began to reassemble the final frame. Without attaching any of the candle supports, she reassembled portions of the adjustable center pole until it was about 3 feet in height. Then she went over to her bag and got out an additional section that was tapered on the tip, almost like a bullet. This she screwed into the top of the pole. She then attached four restraint cuffs to the support rods of the frame. Two were all the way at the bottom by the platform grid and two were about three feet up on the pole. The video quality wasn't the best because only the night security lights were on and it was starting to get dark, but it was obvious that the next thing which she took out of her bag was a black rubber-looking hood with some sort of attached snorkel-like device at the mouth.
