June buffet

Hello, Habrayuzer! With you the June habravpus HabraFurshet!

I remind the format:

A person who is an expert in a particular area leaves a comment where he writes the area of ​​his specialization in bold. For example: “Bypassing antivirus heuristics” , “Mountaineering, sneppling” or even “It is I who change the background in weather issues” . Buffet is a very good way to get answers to questions that can only be learned from experts, the answers that are not found in Google. For specialists, this is a good opportunity to help those who are just starting in their field or just interested in it. Subject is not limited to IT.
