During our last adventure into the realm of format string exploitation, we learned how we can manipulate format specifiers to rewrite a program's memory with an arbitrary value.

The video teaches how to convert degrees Celsius to degrees Fahrenheit. First the boiling points of 32 degrees Fahrenheit and 100 degrees Celsius are plotted on the Y and X axis. Then a line is drawn to join them both. The value m is delta Y (boiling point minus freezing point, i.e., 212-32)/ delta X (boiling point minus freezing point, i.e., 100-0). So m works out to 180/100 or 1.8. Then the formula y=mx+b (intercept of y = 32) is used, substituting X with Celsius and y with Fahrenheit, to c...

Your ability to control exposure in the Camera app is much better in iOS 14. Instead of setting the exposure for a single shot, you can also lock an exposure compensation value for an entire session while you take photos and videos. A session ends as soon as you exit the app, but you can also remind your iPhone to use your last used ECV the next time you open Camera.
