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..
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”)
From http://www.papershredding.ie/waste-disposal.html
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.
When working on a small website project, the client sent an excel file for the database. However this time I intended to use pure XML instead of database, so a CSV->XML tool is needed.
http://www.convertcsv.com/csv-to-xml.htm
This website is exactly the tool I wanted. You can simply upload the CSV and it will convert it to XML for you. You can specify the root and record name for the XML file, makes it an even better tool!
The project brief is simple, come up with some new services and technology that can justify or reinforce the role of library in a school.
Most people started by finding new technologies and new services, to me, it is more important to rethink how education may look like in the future, so that we can easily imagine how the library can evolve to adapt to this new teaching and learning landscape.
“21st century education” is a popular term that coined by many educational scholars and educators. So let’s start by looking at the trend of this education development.
I found this article (http://www.innovationunit.org/knowledge/our-ideas/21st-century-learning) very useful as it points out the role of students, educators and schools in the new era of education. It suggested that students learn through meaningful projects, school as a base camp for enquiry learning, educators regard themselves as learners as well as teachers and Learners collaborate in their learning, rather than ‘consuming’ it.

For a project I had to randomize a given sequence of elements. Here’s the code for generate a unique sequence.
<?
$originalArray=array();
$randomizedArray=array();
$arraySize=10000;
for ($i=0; $i<$arraySize; $i++){
array_push($originalArray, $i);
}
//var_dump($originalArray);
for ($i=0; $i<$arraySize; $i++){
$chosenIndex=rand(0, sizeof($originalArray)-1);
echo ‘chosen index: ‘.$chosenIndex.’, Value: ‘;
array_push($randomizedArray, $originalArray[$chosenIndex]);
//unset and update array size
unset($originalArray[$chosenIndex]);
$originalArray=array_values($originalArray);
echo $randomizedArray[$i].'<br>’;
}
?>
