Paper Folding
I came across this post about folding paper:
Today I am reminded of the episode of Mr. Wizard's World where he explains that a piece of paper (regardless of size) can not be folded more than 8 times...I just conducted my own unscientific scientific experiment and I could only fold the piece of paper 6 times.
I had the same result as well.
This is an interesting problem. It turns out that there is no hard and fast rule that paper cannot be folded in half more than eight times, but it is in that ballpark. Think about it for a moment. By the time you fold the paper in half six times it is as thick as 64 individual sheets of paper. Not easy to fold all together.
More information about this is available from Dr. Math
Hidden Thumbnails
Some digital cameras store information in the images they create in the form of EXIF headers. This metadata may also include a thumbnail. This is great, but not all image editing programs use this. Some, in fact, seem to keep the original information (including the thumbnail) even after the photo has been edited.
This is why I put together the JPEG Thumbnail Checker. It is based around a small utility called jhead and displays the embedded thumbnail (if one exists) from an image the user uploads via the web form.
