I gave my speech in Japanese and unfortunately simultaneous

interpretation was not recorded. So I rewrite important part of my slide into

English for non-Japanese speakers.

To monitor yourself won’t works well. When you are in bad condition, monitoring is also in bad condition. So you can’t

notice you are in bad condition.One solution is monitoring by another person. But sense of

shame and pride will cause problems.

Example


Another solution is monitoring by computer. It solves “shame and pride” problems.


This is a prototype. You can consult with the system to motivate yourself. 13000 people used it and 6000 people was motivated.

But books are not evolved much

We need next generation “book reading”.Computer should monitor human reading books,

and augment its performance.

I think brain-wave and hi-reso HMD are the key to future.1614年9月17日水曜日

4 elements to augment human

• 1: Artifacts: computer, software, etc.

• 2: Language:jargon to refer special concepts, design patterns, etc.

• 3: Methodology: procedure and strategy for solving problems, etc.

• 4: Training: achieve skills to use 1～3

How to discover?→Methodology to find unknown


When you see something...2014年9月17日水曜日

You see some part of the object2114年9月17日水曜日

If you see the object from the left side, it looks like a sphere.

But if you see it from the bottom side, you find it has a tail!

It is the process todiscover unknown


How to discover?→Change Perspective


known ↔ unknown

Two? no, it’s not correct.

Between known and unknown...

不明not obvious

There are things which you don’t know that you don’t know them.

“obvious” = “明” in Japanese2614年9月17日水曜日

blind spot

• Between “Things you know” and “Things you don’t know”, “Things you don’t know that you don’t know them” exists

• You don’t see it, but you don’t notice you don’t see it,that is the blind spot

Comparison

• You can find blind spot by comparing programming languages

“In Ruby, 0 is true?! In Python it is false!”“It differs among languages?”“What is the definition in Python??”

object.__nonzero__(self)Called to implement truth value testing and the built-in operation bool();


History

• You can find blind spot by learning history.

“Why Python has new-style class and old class?”→(Learn history)→ “To unify types and classes? It’s important!” “Old class has problem on method resolution order, so we need new-style class. I got it.”

Unifying types and classes in Python 2.2 | Python.orghttps://www.python.org/download/releases/2.2.3/descrintro


Experience

• You can find blind spot by doing based on your understanding. Especially it won’t work as you think.

“Oops, why 1/2 goes into 0? I think it goes 0.5!”

PEP 238 -- Changing the Division Operatorhttp://legacy.python.org/dev/peps/pep-0238/

Abstraction

• You can find blind spot by learning abstract model and connect it to your experience. It helps you verbalize implicit knowledge.

“Ah, I’m used to the coding pattern but I didn’t know it was called Mediator Pattern!”“Mailing lists are also Mediator Pattern in information sharing domain!”

Abstract model can connect experiences in different domain/person/situation.


Communication

• You can find blind spot by talking with other people who have different experiences.

“I have a problem...” “You can solve it by ...”“Oh! Nice idea!” “But it is common in GUI programming” “Hmm, I don’t know on GUI”

Q&A


Q: Some people ignore the chance to find blind spot. How can I

manage them?


A: “U Theory” is targeting the problem. I’ll give lecture

on that in Kyoto Univ. Summer Design School.

After that you can read my slides on U soon.

http://www.design.kyoto-u.ac.jp/sds2014/ja/theme01.html

A: First, “How to manage others” is not good

attitude. Change yourself first.


A: Second, you (and I) sometimes ignore the

chance to find blind spot too. It’s common. Be aware and be careful. That helps

you find blind spot.4714年9月17日水曜日

A: Start from small step.Make useful result by finding blind spot.

Successful experience make you confident.

←You see, but from your perspective.You draw boundary between self and others,thinking “they don’t do ...(some good action)”


Q: Is it important to make abstract models?


A: Yes, it’s important.


Section 3 of my special feature is how to make

models.

You can read them(but in Japanese)http://gihyo.jp/lifestyle/feature/01/engineer-studying


http://gihyo.jp/lifestyle/feature/01/engineer-studying

http://gihyo.jp/lifestyle/feature/01/engineer-studying

A: Sense of “I got it” is also hypothesis. Hypothesis

should be tested. Do action based on your understanding and check

the result.5514年9月17日水曜日

A: If the result differ from your understanding, it is chance to

adjust your models. To repeat the process you can achieve better models, and then based on that you can make larger model.

This is a method.


A: Another method KJ method and grounded theory. They are used in

domains, in which experiments are difficult.


A: I’ll introduce KJ method roughly. First, collect a lot of data. Don’t filter based on your prejudice. Spread all data on your desk.


A: Human’s woring memory is about seven. But if you put data on your desk, you can see 100~200 data at a time.


A: Seeing 100 data, moving them physically, making

structure from bottom up,and then you get models

on your desk.

(Models in my book and special features are also developed with KJ method)


Q: 5 ways to find blind spot are not same on time

series.


A: Good point. It’s my blind point. Sure, “Abstraction” is follower. A person without any programming experience can not find blind spot

by reading design patterns textbooks. Abstract models in book doesn’t connect to his experience.


Q: How to share know-how among testers.(detail omitted)


A: It looks a problem to share implicit, not

verbalized, knowledge.One method is “work

together”


A: By working together, we can share knowledge without

verbalizing them.Additionally, if one person is prohibited to do anything

except for talking what to do, it prompt verbalization.

Ref: Keith Sawyer "Group Genius: The Creative Power of Collaboration"6514年9月17日水曜日

A: We can make manuals only after we verbalized

our knowledge. Verbalization is difficult job. Delegating the job without any training

is bad idea.6614年9月17日水曜日

Q: I make template to share information and use it. By answering questions, required information will

be collected.


A: Nice method. Even if someone can not verbalize himself, they can answer to specific questions. It’s common. Making good questions are useful.


A: However, be careful. Sometimes we lose

information which is not fit to the template.

Innovative information don’t fit to existing

template.7114年9月17日水曜日
