Kumijo in Aikido and Jodo

Both Jodo and Aikido have two-person jo kata, called kumijo in Aikido.

For jodo, I found this clip from Jean-Pierre Reniez, acting as uke for Matsumara Sensei:

This is is called the Shinto Muso Ryu school of Jodo:

They don’t kiai so much as kind of emit a low controlled angry scream/yell of several seconds, like a challenged, angry tomcat backed into a corner.  This is a little different from the kiai I’m used to in Aikido, which is briefer and louder.

Here is another one from Kenji Matsui explaining jodo moves “as fixed by the All Japan Kendo Federation in 2003″:

There is a comment in the 2nd Youtube above that “Matsumura and Matsui was both taught from Shimizu and Otofuji sensei”.

From Jodo and bayonet training, we get Aiki-Jo.  O Sensei studied Jo and also learned bayonet techniques (jukendo) studied during the war.  The consensus seems to be that the Aiki Jo techniques are actually designed to fit a WW1 era rifle with a bayonet


and that the Shinden Muso Ryu jodo grip and stance is quite different and would not fit a rifle with a bayonet; and that Saito Sensei was the one to write down and codify Aiki Jo as we know it now, leaving aside variants by Chiba and Nishio Sensei.  Here is a clip of O Sensei defending against wooden rifles::

Here are Saito Kumijo clips showing Kumijo 1 through 10:

About that computer with 150 IQ


I read the short Rand paper on Delphi Method by Olaf Helmer from 1967. Summary of Olaf’s version:

  1. Create a model for a real-world problem, decoupled from the actual problem, but with the same moving parts
  2. Ask experts to interact on the model and then individually opine on the outcome
  3. Go through some iterations of voting, maybe you’ll get one consensus opinion, or maybe two
  4. Weight the votes based on prior demonstrated competence of the individual experts in similar questions

Helmer gives an example of forecasting when a computer would achieve an IQ score of 150. Based on Delphi method, the median expectation in 1967 was 1990, with an upper bound of 2000.  I did some Googling on this topic, and the basic answer is: hasn’t happened yet. There was a Swedish professor who made the claim in 2012:

However not much as been heard in the news from him since then.  He does, however, have some very interesting papers on his website.

It turns out that Chinese at Microsoft are the closest to actually getting that done. Interestingly, in both the Swedish Professor case and Microsoft, they use Amazon Mechanical Turk performance as their benchmark in terms of “beating humans” at the test:

In thinking about measuring artificial intelligence, we must be careful in this regard not to fall into the Watson trap identified by Roger Schank:

although Roger has his critics:

Winter binge watching: Hunted


This was a pretty good if somewhat repetitive spy yarn.  Kind of in the Wile E. Coyote genre.


Beautiful blonde spy gets shot up,


heals, kicks ass, gets poisoned,


heals, kicks ass. The bad guys are really bad.  Eventually it ends.  Pleasantly shot and decently paced the whole way.  One or two R-rated scenes per episode to add salt and pepper.


Perfectly mindless entertainment for a middle aged guy.  I was sorry to see it go. Actually a lot like Dollhouse along all of those dimensions, though not superficially similar.

It had some renewal potential but eventually died on the vine after Season 1 ended. The New York Times whinged that Melissa George, the lead actress, was a grade B- version of Claire Danes in Homeland.  I don’t get the connection.  Melissa George was a Playboy magazine cover girl in the late 90’s.


Claire Danes is good at making cry-face.


Melissa George does almost zero cry-face in any of the 8 episodes of this show.  Her whole act is the opposite of cry-face.  In control always, even when she’s not.   So more of a female version of Daniel Craig’s version of James Bond.


I say Craig and not Connery because Connery had some emotion and humor, even when he’s drinking out of a kerosene lantern chimney


and these are not features of Craig’s or George’s performances.  But they are still both watchable.  You just have to be in the mood for in-control stony-face.  The bad guys in the show are all really really bad.  Trump Cabinet bad.


I’d say almost too bad except they look like humanitarians when compared to watching livestreaming confirmation hearings of Tom Price


or Steve Mnuchin.


Gene therapy for 22Q deletion syndrome


22Q is another argument in favor of accelerated application of CRISPR.  There are 4,000 rare genetic conditions out there and this is one that I’ve come into contact with twice, in a cousin’s daughter (I think) and the daughter of a friend from back in the day (definitely).  So it’s prevalence is more than not.  Estimates range from 1:2000 to 1:4000 births.

In my old friend’s daughter’s case, the most threatening complication is that she has, at age 7, required several heart surgeries.   This is the most challenging aspect.  It also comes with learning disability.  My old friend’s daughter just celebrating being placed in a general population 1st grade class.

It’s fair to ask what has been done in the gene therapy realm for this.  Answer: Nothing. Some money is being spent on genetics.  My Google search hasn’t come up with anybody trying to cure it directly with gene therapy, however, and only opportunistic fixes exist for complications that result (heart surgery for example).

So, deep-pocketed gene therapy aficionados, if you’re out there: this is an application waiting to happen.

What’s new in lunar colonization


My son is reading a novel targeted to 3rd graders called Space Case.  This got me curious about the latest thinking in moon bases, and I downloaded Google Moon to have a look at the property.  Here is the latest thinking on the matter:

  • The Lunar South Pole has best combination of water and almost constant illumination at points, and is much explored compared to the Lunar North Pole.  The South Pole is cenetered in the Shackleton Crater.
  • Communication delay is only 3 seconds, which makes it very amenable to remote control of automatic processes like robot construction.
  • We should send robots to build and test habitats first using 3D printing of moon dust.
  • The best place to build a house is in a lava tube.
  • Watch out for moon dust, that’s a major challenge, and probably would make lunar living very annoying, like living amongst the fiberglass insulation of an attic.
  • Google has a prize with a fairly imminent launch date for commercial landing of a lunar rover.  Is it my imagination or is Google now outsourced NASA and new IBM?

It doesn’t look like it will be fun for a long time.  It should happen before anybody lands on Mars.

Winter robot drama first impressions: HUM∀NS *spoilers maybe*


I’m just trying to re-start watching this series.  It is a much more naturalistic and disturbing version of WestWorld.  Also beautifully photographed, well-acted, and maybe a little bit dull.  It starts on a slave rebellion plot right away.  The human reactions to humanoid robots in the home is legitimately cringey and creepy when they are obviously sentient.  I found the rebellion plot a bit trite, especially in our face right away.  There’s no subtlety in that.  I found the extremely well-portrayed discomfort of wives and husbands seeing themselves being effectively replaced by machines to be, well, extremely discomforting.  So much so that it pushed the boundaries of what I will watch for entertainment and relaxation.   I am too old to be edified.  So I didn’t finish the episode first time around.  However, I have been calloused by bingeing WestWorld, DollHouse, and other similar shows with intersecting themes like Firefly, Lucy and Her.  So I think I have the strength to continue with this show, though I’m not convinced it will be entertaining enough want to.  It’s kind of an overly naturalistic, realistic and disturbing highbrow BBC treatment of a topic that we are now confronted with every day when we check out our groceries ourselves at a machine, get cash from an automated teller, and receive driving directions from a GPS.

Winter K-Drama initial thoughts: Cheese in the trap *spoilers*


I have been sort of liking Cheese in the trap except that it has received

which are influencing my thinking.  The reviews are consistent in saying that

  1. The “webtoon” (can’t get used to that term) was canonical and superior
  2. In the webtoon, Male Lead was a true sociopath, but this is softened in the TV series….to the detriment of the character
  3. The TV series has some kind of tonal shift after Episode 10, goes off the rails, and gives way too much time to Second Male Lead
  4. Male Lead and Female Lead don’t get together in the end, big bummer for this type of series

These faults are attributed to a rushed and incompetent showrunner on the TV adaptation side, and just general creative chaos.

So I’m not sure I’m going to tough it out.  After having watched 20 or 30 Korean Dramas, I am starting to get just a little picky, and push back now when I think bad results come from commercial laziness or incompetence rather than true risk-taking.  I will watch any crappy series to the end if I think the showrunners were sincerely doing their best and trying to take risks.  I don’t want to put that time in if they are just having a bad day.

On the small plus side, the production values are good: Photography is clean, sets are nice, actors are good, the thing plays well.  It’s just that it may be playing into a wall.
