HN discussionIt's worth mentioning that many smartphone users upload content to Youtube seemingly mistakenly and unaware that they are doing so (also known as fat-fingering[0]). A quick search for: DSC001.mp4 And then filtering that by recently uploaded always yields interesting results. For those that don't know, `DSC-XXX` is a standard naming scheme for digital cameras. More on the default naming scheme in the following link[1…

HN discussion"You are given two eggs, and access to a 100-storey building. Both eggs are identical. The aim is to find out the highest floor from which an egg will not break when dropped out of a window from that floor. If an egg is dropped and does not break, it is undamaged and can be dropped again. However, once an egg is broken, that’s it for that egg. If an egg breaks when dropped from floor n, then it would also have broke…

HN discussionPCI-compliant networks often contain checks for credit card numbers being sent in plaintext over the network. Problem with that is that credit card numbers are computed according to a formula, and it's really easy to generate a bunch of fake 16-digit numbers that will pass the check. So if you want to troll your security team, generate a CSV with a stack of credit card numbers and drop it in a few places on a server…
