Self learning and textbook

Just watched Good Will hunting over the weekend in memory of Robin Williams. How a teacher inspire students in an elite school in Dead Poet Society was certainly up-lifting for me as an educator. The friendship/brotherhood in Good Will Hunting was also touching. A scene in the movie made me think about what learning is/could be.

Not everyone has the incredible memory that Will has in the movie, but we have access to the books he read. The interesting thing is what he chose to read, not just any book but textbooks! It really is the quickest way of diving in any field if you know nothing about it. I may start with the recommendations on this page and keep an eye on the College Open Textbooks (http://www.collegeopentextbooks.org/) project.

How we see the world differently with mobile phone- VVS

This is probable an old video, but it is really funny. Shooting video in portrait with mobile phone, also known as “Vertical Video Syndrome”/VVS.

What we can see here is the merging of 2 different technologies (video tech and mobile phone). The vertical format of most mobile phones is definitely a sensible design, but it wouldn’t work when the orientation of the camera (landscape/portrait) correspond to the orientation of phone. What is the solution?

A simple approach maybe having a phone that shoots in landscape mode while being hold “up-right”.

Mm… why isn’t there a phone like this?

Using Google Drive to share documents

One of the problems of using GDrive in a school/company is the file ownership. If someone who owned/created the file left and the account was deleted, it will be gone forever. I order to further migrate the data to the cloud service, transfer the ownership to a “school owned” account is essential.

However, explaining all these by an email would be extremely boring… Finally I’ve created my first PowToon..

Prejudice and door lock

Which one is more powerful? A door lock or prejudice?

I encountered 2 broken door lock incidents in the past few days, luckily nothing went wrong. 

One of the door usually requires a smartcard to open, as the system was faulty that day, someone disabled the lock to make sure people have access to it. However I still swipe my card every time when I push an unlocked door…

Here’s an image of a classic InfoSec theory (Which is about “CIA”)

It talks about integrity, availability and confidentially. If you are living in an apartment building in Hong Kong, most of the time if you forgot to lock the door, nothing will happen. The challenge for anyone who’s trying to break in an apartment/system is that there’s a cost for testing each door. Most people will assume a door is “locked”.

How about when we try to share a new idea? Do we assume people will not take it and just drop it? To me, prejudice is much more powerful than a door lock, cause after all, we all assume a door lock can lock the door… but it isn’t always the case.
