I wonder how many Sundays are between June 17th 2012 and today?

WolframAlpha: 79.

Ho. Lee. Crap. That’s awesome.

You do know about WolframAlpha, right? …the “computational knowledge engine”? No? Go there. Ask it things.

Stephen Wolfram is a character. (But anyone whose thesis committee contains Richard Feynman gets a complete pass in my book.) “This math stuff is annoying…” Bam! Mathematica. And if you want to really go “whaaaaaaaaaaaaaaaaaaat?!”, try to wrap your brain around, A New Kind of Science.

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.

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.
