> When comparing password hashes, use constant time comparison instead of ==.
If you were comparing plaintext you'd get some info, but it seems overly cautious when comparing salted hashes. Maybe anticipating an unknown vulnerability in the hash function?
A lot of recent models also support "picture by picture" mode, allowing you to connect two separate inputs to the monitor and avoid doing anything in software.
To me, the rhythm of an informative first message feels more natural than responding to someone's ping and waiting 2 minutes for the follow-up.
Second, they point out that viewers almost always view pictures from the “wrong” location. A cornerstone of linear perspective is the idea that the viewer must be at the focal center of the image to view it correctly. If you view a linear perspective image from the focal center, it should be like looking through a window—indeed, Leonardo da Vinci wrote that linear perspective images only work from the focal center. Yet, in reality we don’t do this. Most of the photos we look at would have to be viewed with one’s eye a few inches from the page. People in art galleries walk all around and view paintings from all sorts of angles. Hence, the whole idea of linear perspective falls apart.
If your car breaks down twice, the second time still sucks due to the core problems of money and time loss, but you now have less uncertainty surrounding the logistics+scope of getting it fixed.
