Joy of Life: Volume 1 Chapter 3

Volume One: The City by the Sea
-- written by Maoni

Chapter 3: Training and Schooling


Fan Xian had no idea that he was training in a very profound inner energy manuscript. Any normal martial art student would have trained with the utter most scrupulousness and prudence; furthermore, he would undoubtedly ask his master or trustworthy friends to monitor alongside.
The most dangerous part of the manuscript was at the very beginning. When depositing energy into the Snow Mountain of the Dantian[1], the practitioner’s reaction time with respect to his body would become dramatically slower than his mind, and the direct result being that the practitioner would feel as though he had completely lost control of his body.
If the practitioner had no such prior experience, he would easily come to the conclusion that he was going through a fire deviation[2], and then forcefully retract the inner energy – if he were lucky, and if he were exceptionally good at controlling his inner energy flow, he could possibly direct the energy inside his body back into the various chi channels and meridians; but that would also mean the practice achieved nothing. For new learners, such panic could very likely lead to obstacles with one’s spirit and mind.
Being a new learner, the fact that Fan Xian didn’t end up with fire deviation, yet even had a better understanding of the profound experience than those advanced practitioners must be attributed to his life experience and luck.
When he started to train in the nameless inner energy, he lived inside the body of an infant, which had not returned most of the congenital energy inherited from the mother’s womb back to the outside world. With this inside his body, he could get twice the result with half the effort. Additionally, most of the congenital energy actually ended up stored inside his chi channels and meridians magically.
The most common problem of obstacles in spirit and mind for practitioners didn’t cause many problems for Fan Xian.
In his prior life, Fan Xian lived in a sickbed for several years and was already accustomed to not being able to control his body with his mind. When he had the similar feeling, he didn’t panic. Instead, he actually felt slight joy and warmth for being able to find some of the remnant memories.
When he trained for the first time, even though he felt as though the energy streams inside him seemed chaotic and he felt his mind was disconnected from his body, he wasn’t afraid at all. Because there was no interference from fear, his mind was clear and focused. He overcame the most difficult barrier with ease.
Ever since then, training became easy. All he had to do was to recite the scripts inside his head, and then he would naturally enter a state of trance – that was why each day’s nap time for Fan Xian was a very pleasant experience, and why it was so hard to wake him up.
For an ordinary inner energy practitioner, entering into a state of meditation trance would have required good luck together with special circumstances. Using everyday’s nap in place of meditation was indeed a luxury no one could have imagined.
God certainly had special favor for this kid.
……
……
Once he was awake, Fan Xian would roll his delicate and lovely little face swiftly in the warm towel in the servant girl’s hands, which counted as a face wash. Then in the afternoon, it was time to take lessons in the study from the literature teacher, who was respectably invited by the Count’s Manor from the East-Sea County. The teacher wasn’t very old, roughly in his thirties, yet carried the distinct flavor of a pedantic scholar.
A literature improvement movement had being going on in the Qing Empire for the last ten years, initiated by an article calling for improvement in literary works written by the Minister of the Literature Cabinet, Mister Hu. Today’s world of literary was filled with battles between the ancient prose style and the modern text style.
The ancient prose style was identical to the Classical Chinese style[3] in Fan Xian’s memory. The modern text style was similar to Vernacular Chinese style[4], only with more elegant wording.
Fan Xian’s teacher was a fan of the ancient prose style, so Fan Xian’s curriculum included many classic scriptures. Although these scriptures were not the same as the Four Books and the Five Classics[5], interestingly, the contents and ideas weren’t that different, and also had the separation of Confucianism, Mohist School, Legalists, and Taoism.
As a result, during the first lesson, Fan Xian became very suspicious about where he really was.
It was a very hot and muggy summer day. The study was also hot and humid. The teacher pushed open the south-facing window, and immediately the singing of cicadas entered the room together with the cooling breeze. Turning around, the teacher found his little pupil bending over the desk staring blankly. He was just about to reprimand him when he suddenly caught sight of that innocent little face, which touched a soft spot in his heart.
The teacher actually took pleasure in the little pupil of his. At such a young age, the kid was able to speak orderly, and even comprehend somewhat the sublime words with deep meaning in the scriptures. It was really no easy task for a mere four-year-old.
The teacher also had doubts himself. Why was the Count of Southernland so anxious and had such high demands in the invitation letter to him? Because of such high pressure, he had no choice but to teach the four-year-old books of scripture. If it had been a normal family, kids at this age would have been learning just characters and memorizing some beginning literature.
When the lesson was over, Fan Xian saluted the teacher in good manners, and then waited respectfully until the teacher left the study. Then stripping off the sweat-soaked robe, he ran out of the study, as the servant girl followed hurriedly while calling out for him to be careful.
As soon as he entered the main courtyard, Fan Xian stopped running. Putting out the most innocent smile on his face, he strolled inside, and as soon as he saw the Old Madam sitting in the middle of the hall, he called out in his baby voice, “Grandma!”
The Old Madam’s face was kind and affable, and the deep wrinkles were clear marks of the many passing years. Only the occasional shine in her eyes would briefly reveal her shrewdness and the fact that she was not just a simple woman – it was said that the Count of Southernland would not have been able to achieve his fame and power without the Old Madam’s connections in the Capital City.
“What have you learned today?”
Fan Xian stood obediently in front of the Old Madam’s chair and described what the teacher had taught him that day. Then after a respectful salute, he headed toward the side hall to have dinner together with his younger sister.
The Old Madam and her grandson didn’t seem to be very close to each other. Maybe it was because Fan Xian was only a baseborn son, though the Old Madam didn’t mistreat him. She always had high demands for him, which naturally resulted in the estrangement.
Fan Xian could still remember that when he had been only one year old, the Old Madam had once held him tightly in her arms late at night and wept dearly. The Old Madam, of course, did not think a one year old infant would understand her words, or even remember them.
“Kid, if you have to blame, then blame your father. You poor little thing! Losing your mother right after you came to this world.”
……
……
What kind of family did he belong to? That was the biggest question occupying Fan Xian’s mind. He had already experienced an assassination right after he came to this world. Even though he already knew his father was a high-ranking official in the Capital City, the Count of Southernland, who he had never met in person, but who was his mother? At the time of the assassination, the Count of Southernland was still at His Majesty’s service in the conquering army. Those assassins certainly had targeted his mother directly.
Since the soul inside his body really belonged to another world, he obviously didn’t think much of the father-son relation between him and the never-met Count of Southernland. Only occasionally, he would think of that woman who had already left this world, the woman who he should have called mother.

Robot of the Day: Ikhana, another Predetor UAV used by NASA to support fire-fighting

In my previous posts, I shows the MQ-1 Predator and the MQ-9 Predator B Reaper UAVs. I feel obligated, especially after the previous post talking about my opinion on using military technology for civilian use, to introduce you another Predator UAV used exclusively for scientific data collection and fire-fighting support: The NASA Ikhana Unmanned Science and Research Aircraft System


The name Ikhana is a native American word that means "intelligence". It is really just a MQ-9 Predator B Reaper, except the payload does not include missiles or bombs, but scientific equipments (mostly additional sensors, such as thermal sensors) used to help see through heavy smokes from wild fires. Instead of killing people, the Predator UAV is used to save lives, lives of firefighters or local residents affected by wild fires.


Talking about fire-fighting, there were two big fires, the "Station Fire" and the "Guiberson Fire", near Los Angeles in the last California fire season. These two fires were very close to local residence and damaged and threatened many houses and properties. Ikhana was used for data collection in the Station Fire. Although the Ikhana UAV was not used in the Guiberson fire, I was fortunately enough to be part of a NASA team (as a continuation of my summer internship with NASA) and actually flew to LA and participated the fire-fighting, working on another NASA project in support of the fire fighters to better collect information. This project is called GeoCam, and it is the topic of another blog post in the near future.

Picture of the Day:


Here's me videotaping a user from the US Forest Service using an android phone (running our GeoCam client software) to take picture of a live fire at the Guiberson Fire, and he took a picture of me instead. The other person in the picture is the technical manager of the project, a NASA scientist.

AI and Robots: Rise of the Machines -- Robotics Professors Discussing AI

Yes, they are coming, the robots and the intelligent machines, into every aspect of our lives. Is this good or bad? Are we understanding humanity better during the process? Or are we really digging our own graves?

Why are people so fascinated by robots? (I know my answer: I want build a robot that do all my work! :) Why do humans have such a dystopian view of the future where robots are concerned? These are some of the questions asked in an interview with Noel Sharkey,a Robotics and Artificial Intelligence professor at University of Sheffield, UK. When asked when the first mass produced robots will have a serious impact on society? Dr. Sharkey expressed his concerns about the advances of military robots. (Remember the Predator, Reaper robots we talked about recently?)

Every roboticists and AI researchers in the US know that the majority of the research in this field are driven by military funding and initiatives. The biggest one of them all is DARPA -- standing for Defense Advanced Research Projects Agency. Many of you might not be aware that the Internet actually was created in a research program of ARPA (the earlier name for DARPA). As a matter of fact, part of my research is funded by the Army Research Lab. After all, there's not much different between Search and Rescue and Seek and Destroy.

I, and I believe a great number of other researchers, are strong believers of Azimov's Three Laws of Robotics, especially the first half of the first one:
A robot may not injure a human being or, through inaction, allow a human being to come to harm.
Other other hand, I also must admit that the military driving force drove the advancement of technology, which benefits the entire human race. Just to name a few: the Internet, Satellites, cell networks. Therefore, the stance I take on this issue is that robotics and AI technologies developed for military purposes can also be used for normal people, and I shall work very hard to help make that into reality.









So how do we make sure we don't create the Terminator Scenario? Some people believe we should upgrade ourselves and turn ourselves into cyborgs (half human and half machine), so we still dominate the world, instead of robots. A robotics researcher friend of mine at NASA Ames (no mentioning names) holds this view, and a Robotics and Artificial Intelligence professor at the University of Redding, UK, is another strong believer.










My guess is that robots will become more capable and intelligent, and humans will also become more capable with wearable devices or implanted devices. There are already robotic suits enabling wearers to carry weights far exceeding human capabilities, and there are also robotic hands that connect directly to nerves in people's arms controllable by human brain. I am SERIOUSLY not joking about these things, and you'll reading more about them in my future blog posts (specifically under the Robot of the Day label).

Whether to rely on robots or becoming a cyborg is your own choice, but the time that you have to make that choice might not be very far in the future. There's at least one thing clear: We live in a very exciting era of the world, and we should enjoy it!!

AI and Robots: Insurgents "Hack" U.S. Drones

The Predator series of unmanned drones have been great weapons for the US government to fight terrorists and insurgents (see my previous posts). The US Department of Defense actually plans to replace one-third of military planes with unmanned drones. Any sensible person would have agreed that these unmanned drones are very sophisticated and advanced technologies highly classified because of the military and intelligence associations. However, on December 17, 2009, an article on Wall Street Journal reviewed that:
Militants in Iraq have used $26 off-the-shelf software to intercept live video feeds from U.S. Predator drones, potentially providing them with information they need to evade or monitor U.S. military operations.
WHAT???!!! When I first heard this on the NPR radio, I was on my way home, and I almost swerved off the road at this shocking news! This is unbelievable! I know the video downlink from our research UAVs are not encrypted, which means anyone with an antenna, a comm box, and a video capturing software could download video feeds from our planes. But come on! We are talking about 12 million dollars drones used by the U.S. Air Force and the CIA to fight real wars! Haven't they ever heard of the word "Encryption"? Even my neighbors' wireless networks are encrypted and cannot be accessed without a password. This is simply beyond my pithy understanding! The article used the word "hack" in the title. Did the insurgents really had to hack? The door was wide-open.

Imagine a bored terrorist pulling his laptop out to kill some free time by watching some real-time war clips, then he sees his terrorist friend's bunker in the live video feed, so he calls his friend and says, "Start your SkyGrabber program, man, I think that's your bunker!"
U.S. military personnel in Iraq discovered the problem late last year when they apprehended a Shiite militant whose laptop contained files of intercepted drone video feeds. In July, the U.S. military found pirated drone video feeds on other militant laptops, leading some officials to conclude that militant groups trained and funded by Iran were regularly intercepting feeds.





According to Dan Verton, a cyberterrorism expert, "we thought that this particular enemy was either incapable or not interested in learning how to do this...we've always been wrong on both accounts!" This is simply amazing! Didn't we know there's the Internet, and you can find tutorials for anything you want? Amazing!

"It is part of their kit now."


That's got to be the best line of the story! Especially at the thought that maybe they didn't even have to buy multiple copies and simply used pirated copies.

What's the merit of the story? Human stupidity is far more powerful than machine intelligence! As a matter of fact, I'll make that my Tao of the Day!





Human stupidity is far more powerful than machine intelligence!

Robot of the Day: MQ-9 Reaper

Since I am really in this UAV mood, let's talk about another UAV (Unmanned Aerial Vehicle) today.

The MQ-9 Predator B Reaper is a scaled up version of the MQ-1 Predator UAV we discussed in the previous post. It is also designed by General Atomics Aeronautical Systems, only larger, faster, more powerful, and much, much more deadly!

Picture credit: U.S. Air Force

Reaper was designed to be a hunter-killer, hence the name. It has a wingspan of 66 feet (20.12m), can fly at an impressive 300 miles per hour, and can stay in the air for up to 30 hours. The Reaper UAV is still powered by propellers at the rear end of the plane. It can carry 3800 lb of weapons. For example, it can carry 14 Hellfire missiles or other weapons such as the 500-pound, laser-guided bombs shown in the picture above. The U.S. Air Force was activated to operate the MQ-9 Reaper UAVs on May 1, 2007.

Fully loaded Reaper!





Looks like the U.S. Customs and Border Protection also upgraded their UAVs to the Predator B Reapers!

Disclaimer: This is not my house. Read the story below!

 

"Good news is that I truly out did myself this year with my Christmas decorations. The bad news is that I had to take him down after two days. I had more people come screaming up to my house than ever. Great stories. But two things made me take it down.


First, the cops advised me that it would cause traffic accidents as they almost wrecked when they drove by.

Second, a 55 year old lady grabbed the 75 pound ladder almost killed herself putting it against my house and didn’t realize that it was fake until she climbed to the top (she was not happy). By the way, she was one of the many people who attempted to do that. My yard couldn’t take it either. I have more than a few tire tracks where people literally drove up my yard."
