In this article (The Four Horsemen of the Cyber Apocalypse) , it talks about the possible scenarios that will paralyse digital system. They are certainly valid but I can’t stop thinking of a this question, what is the tipping point for people start to move back to paper-based system?
Given the current database and networking technology, there’s almost no real “safe” system that can be created and left alone without being upgraded. Let alone the attach to cloud based service, for institutes that efficiency is not the top priority, paper based system could be a better solution in terms of security.
In the Silo series written by Hugh Howey, it described a post-apocalypse scenario that the whole human kind lives underground. The “history” of the earth is being modified and changed in the database so no one really know what happened, except for the managements of the silos. This top administrator of the silo has access to physical books, which document the “real history” of the past.
Let alone whether there’s a “real history/reality“, just by thinking about this digital history rewriting scenario is scary enough. There are legal requirements for some institute to keep paper-based record, but is there any company/institute that want to move back to paper-based record/database from a digital system? What is the cost of it? Is there any formula for that?
To boil it down to one question, how much does it cost to convert a database (e.g. MySQL/Postgresql) to a paper-based system?
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.
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..
Have been organizing information literacy and research skills lesson. Found a lot of resources on the internet. Here’s the list.
NYC Department of Education Information/Digital Literacy resources page include a lot of useful information.
Ontario School Library Association (OSLA) Information Studies Curriculumn
A very useful resource for lessons plans in different subjects, the one above is for research skills.
An interactive map for young students to learn how to do research, good for lower grade students (e.g. G6)
Google Advance Search Lesson Plans
A very comprehensive website for educators on advance search in Google. It comes with detail lesson plans, slide shows, activities and even video.
Understanding the concept of join statement in SQL has been a difficult challenge to many, even some experienced programmer.
This page http://www.codeproject.com/Articles/33052/Visual-Representation-of-SQL-Joins provides a very clear, graphical explanation on what SQL join statements actually do.
Whenever I go to visit primary school I see so many interesting apps that are either freely available, or extremely useful in classroom. Is make me think of collecting apps review site. Do you have any recommendation in apps review site?
