Facial Recognition and Retouching Software

I was impressed by the Youcam Makeup software.  It allows you to fudge with photos.  I think it was primarily intended for women to retouch selfies.  I am sure you like to imagine women retouching their selfies but it is even more fun to alter the photos of your straight male friends who might feel a little less than flamboyant.

I was really hoping I could tranify the doggy too but that was a no go.  Perhaps there are manual settings.  This was done on an Android phone.

Vigenere Cipher And Breaking it

This code was originally thought to be unbreakable. You use a key such as PASSWORD.  Each Letter in your message is encoded by placing

PASSWORDPASSWORDPASSWORD

THISISATESTOFTHECODE

Each letter is encoded by selecting the corresponding column from the key letter above your message letter.  The obvious failing is that after a bit you run out of key and start repeating.  This makes the code subject to frequency analysis.  Of course if your key word is a phrase of some length you might be able to avoid that.

It is interesting that only about 150 years ago this would be considered unbreakable.

Video: The Camera that Changed the World

Before about 1960 movie cameras were heavy items that required a tripod.  Any camera that was small enough to film by hand made too much noise to get good audio.  Two separate people at about the same time got the idea to make a hand carry movie camera that could capture audio.   It's quite a contrast to the present day where video cameras are ubiquitous.
