These days we tend to do more screen reading than traditional book reading. While it is okay to read blogs, news-feeds etc off the screen, certain materials like tutorials and how-tos need to be studied leisurely.
Taking printout on A4 sheets is ok, but it is still not so convenient. To have a good feel of reading, the material should be of book-size, with ample margin for binding and should be held open with a thumb or thumb and the little finger. I have always been loking for an app which can do booklet printing. The other day I found just that.
You can just right click on a file and generate a booklet in a size of your choice. what’s more , you save a lot of paper.
There are many apps which only a minuscule few may want, and big IT companies don’t care. An open source software enthusiast, who needs such a feature, looks around, to see if it is available. If not available he proceeds to develop one, alone or with other like minded people.
And once a facility is developed, the real fun is in freely sharing it with the whole world. That is the spirit of Ubuntu, a far cry from the software giants who toil hard to produce stuff people don’t need and toil harder to sell it to them at exorbitant prices.
