My Best Teaching Is One-on-One

一対一が僕のベスト

Of course, I team teach and do special lessons, etc.

当然、先生方と共同レッスンも、特別レッスンの指導もします。

But my best work in the classroom is after the lesson is over --
going one-on-one,
helping individual students with their assignments.

しかし、僕の一番意味あると思っている仕事は、講義が終わってから、
一対一と
個人的にその課題の勉強を応援することです。

It's kind of like with computer programs, walking the client through hands-on.
The job isn't really done until the customer is using the program.

まあ、コンピュータプログラムにすると、得意先の方に出来上がった製品を体験させるようなことと思います。
役に立たない製品はまだ製品になっていないと同様です。

Principles of Security

Security. Lots of computer system companies are selling security these days. Ironic, when you think about it, because computer systems are systems, and systems are inherently, well, vulnerable. Not secure.

It's a feature of systems, even though systems designers from the times of the earliest recorded history have habitually insisted their systems are somehow different. (Vulnerability is not just a feature of mechanical systems.)

Security in the usual sense is a red herring, a distraction.

But if you want security, here are the two principal keys:

Know who you are and where you are.

Know what is most important and where it is.

If you don't know the above, what use is building walls?

If you do know the above, chances are you'll have little use for walls. Just enough to keep other people from getting worried.

This all sounds ridiculous, but it has practical application in computer and information science. Systems must understand identity at some level to be secure.

Which begs the question, what is identity?
