Slate and Slate Pencils

Slate and Slate Pencils

Digital devices are good for teachers and I am not sure whether too much of technology will be goo for kids.

Children have to use fine motor and gross motor skills as they grow.
Slate and the slate pencil were the primitive but sure way to learn finer motor skills and specially the hand writing.
In the west they are even banning cursive writing and when the grow up I cannot think of them becoming neurosurgeons (microsurgery need hand skills that are properly developed as children and not as adults) or eye surgeons.
We might have to use rots to do surgery then.
I had my granite slate till I was 25 years old and I gave it to a poor kid and he did not keep it for even three months.
In this consumerist society people do not value conservation and the amount of plastic junk we are collecting we won't be able to clean up for 100 years.
My slate was very special to me.
One side there was horizontal lines and the other side there were squares and I could practice as much as I wanted and my saliva was the best wet cleaner. My hand writing were no very good at least they were legible till I became a practicing physician and they automatically became illegible again. Point I am driving is slate was eco-friendly and there were no papers and no trees chopped down, then.
We are heralding an era of paperless and digital era and the rime is right for slate again if not digital pads.

I am not saying we much go backward what I am stressing is that manual dexterity and fine motor skills were something we developed in evolution and apes do not have these skills.
A monkey cannot open a door holding the knob and as kids we could not do that and we had to learn it and if technology retard our finer motor skills I do not know what will happen to us 100 years from now?
Calibre and DRM (Digital Rights Management)

Testing Linux distribution plunge me into deep waters but very often I find some interesting stuff.
Calibre is an Open Source E-Book Management System I found already installed in Pinguy / Ping Eee.
If you don't have it go to its website (there is a good demo) and download free. I belive it has a Microsoft version too.
It does the following.

1. Manages your E-book library

2. Converts the E-books to the device format for Reading

3. It synchronizes the device with your computer and exchange device to computer and vice versa

4. It is a E-book Viewer

5. Download e-books and news around the world

If you are good reader like me  this cute little program is for you.

Now then what is DRM?

It is Digital Rights Management system by which publishers and device (OEM) developers prevent infringement of copyrights of the digitally available material.

There are four main ebook formats at present.  

Mobipocket,

Topaz,

EPub and PDF.
The Amazon Kindle uses Mobipocket and Topaz and it also supports native PDF format ebooks and native PDF files.
Other ebook readers mostly use ePub format ebooks, but with differing DRM schemes.
Some call it Digital Restrictions Management and whatever the way one interpret it there is a law that prevent copying.
Not only e-books, audio, video and even TV shows are protected.
In time to come even in the developing world we might see tablets and  E-readers instead of slates and slate pencils which I used when I was a kid.
