Interview with Koichi Tohei

The way people most talk about ki these days tends toward the occultish, but I will say that I have never done anything even remotely involving the occult. Much of what Ueshiba Sensei talked about, on the other hand, did sound like the occult.

In any case, I began studying aikido because I saw that Ueshiba Sensei had truly mastered the art of relaxing. It was because he was relaxed, in fact, that he could generate so much power. I became his student with the intention of learning that from him. To be honest, I never really listened to most of the other things he said.

Stories about Ueshiba Sensei moving instantaneously or pulling pine trees from the ground and swinging them around are all just tall tales. I’ve always urged aikido people to avoid writing things like that. Unfortunately, many people don’t seem to listen. Instead, they just decrease the size of the tree in the story from some massive thing to one only about ten centimeters in diameter. In reality, it’s pretty difficult to pull even a single burdock root out of the ground, so how in the world is someone going to extract a ten centimeter pine tree, especially while standing on its root system? Such things are nothing but exaggerations of the kind often used in old-fashioned storytelling.

The stories have gotten rather incredible since Ueshiba Sensei passed away, and now people are having him moving instantaneously or reappearing suddenly from a kilometer away and other nonsense. I was with Ueshiba Sensei for a long time and can tell you that he possessed no supernatural powers.

How to discuss politics

Of course, one way to make sure you never sound like an idiot when discussing politics (or have to suffer someone else who does) is to just avoid discussing politics in polite company. That said, sometimes a spirited discussion on current events is fun and informative, and sometimes you have the opportunity to talk to someone with an opinion or background you’d like to benefit from. In this post, we’ll show you how to approach those political conversations from an informed, civil angle, without a conversation with someone you may disagree with devolving into a mouth-frothing mess like you’d see on Sunday Morning talk shows.

Mathematics

To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature. C.P. Snow talked about two cultures. I really think that those two cultures separate people who have and people who have not had this experience of understanding mathematics well enough to appreciate nature once. […] Physicists cannot make a conversion to any other language. If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in. She offers her information only in one form; we are not so unhumble as to demand that she change before we pay any attention.

Control T for TENEX

This magic works via detection of a STATUS control character, Control-T, by the kernel tty driver, which then prints the load line via tty_info() on FreeBSD or ttyinfo_locked() on Mac OS X. It also sends a SIGINFO to the process, so it can run its own routine. See STATUS in the termios(4) man page.

Prioritize practical movement

Natural human movement comprises locomotive skills such as walking, running, balancing, jumping, crawling, climbing, or swimming; manipulative skills such as lifting, carrying, throwing, and catching; and combative skills such as striking and grappling. In today’s comfortable world we are losing sight of the practicality of these skills, yet their value cannot be ignored whenever a life-threatening situation arises. You might have to run for your life, or climb, swim, fight, lift, etc. These abilities can save not only your own life, but that of strangers and loved ones as well. George Hebert said, “Be strong to be useful.” Do you want to be strong and useful? Then prioritize practical ways to move.

New knee ligament discovered. Again.

Orthopedic surgeons in Belgium have hunted down the enigmatic structure in cadavers. And what do you know — the good Parisian doctor [who discovered it 150 years ago] was right.

There is an overlooked ligament in the knee. And it might be important for keeping your knee from twisting and turning, especially after an injury to the anterior cruciate ligament, or ACL.

5 million tons of rubbish

Five millions tons of rubbish made up of devastated homes, boats, cars and businesses is making its way across the Pacific Ocean following the 2011 tsunami in Japan.

The article’s characterization of the debris as a “floating island” is certainly hyperbole. But still, this is a HUGE amount of floating debris.

You might try mowing the lawn

Researchers in Sweden measured the health of almost 4,000 60-year-olds in the late 1990s. A dozen years later, they checked back in. The people who had been active but not “exercising” at age 60 had a 27 percent lower risk of heart attack and stroke over that time, and a 30 percent lower risk of death.

What kind of activity does it take to get those kind of numbers? Things like mowing the lawn, housework, fix-it projects, gardening, bicycling, and, for a nice Scandinavian touch, “gathering mushrooms or berries.”

Repercussions

If I were in government right now, I would be leery of starting another big software project. I’d also know that big software projects are going to be necessary as our civilization gets more and more complex. So, if I were in government right now, I’d be thinking about laws to regulate the Software Industry. I’d be thinking about what languages and processes we should force them to use, what auditing should be done, what schooling is necessary, etc. etc. I’d be thinking about passing laws to get this unruly and chaotic industry under some kind of control.

If I were the President right now, I might even be thinking about creating a new Czar or Cabinet position: The Secretary of Software Quality. Someone who could regulate this misbehaving industry upon which so much of our future depends.

Maybe that thought hasn’t occurred to them yet. Maybe. But how many more healthcare.gov debacles will it take before it does?

Most people I’ve talked to, (who write software or do systems and network administration,) are in the “I have work to do” camp. They’ve no time to think about professionalization, or standardization, of their field. To which I say:

That’s cool; I understand. No worries! The government will eventually get around to ramming standardization and licensing down your throat. I’m sure that will work out well for us.

If you work in these fields, you should be paying attention. If you wok in network and systems administration, you should be paying attention to LOPSA and Usenix/LISA.
