Difference between Turtle and Tortoise

Whenever I see a Tortoise or Turtle I don’t know what I should say to my 3 year old kid. I didn’t want to confuse him by saying sometimes this a Tortoise and sometimes this is a Turtle. I reminded myself to checkout the difference about these two in internet someday. So today I did just that, and I got answers.

Important difference is it if stays only on land its Tortoise and if it stays in water its Turtle. you can read more about this here Turtle & Tortoise

Merge PDF

I have had couple of occasions where I had to print more than 1 PDF file, but problem was if I sent each PDF one by one to the printer, the printer prints each PDF with this own covering page.
This was not environmentally good, because we are wasting not 1 covering page, but more.

So I searched and found this nice tool, which takes in PDFs and gives output merged as 1 PDF.
