Conference DEFCON 18. Troll reverse engineering with the help of mathematics

Trolling with math is what I'm going to talk about. This is not some kind of fashionable hacker stuff, rather, it’s an artistic expression, a funny, intelligent technology so that people would consider you a jerk. Now I will check if my report is ready for display on the screen. It seems everything is going fine, so I can introduce myself. 3r37474.  3r33490. 3r37474.  3r33490. Conference DEFCON 18.

The theory of happiness. Accidents are nonrandom

The theory of happiness. Accidents are nonrandom 3r3618. 3r3-31. 3r33584. I continue to acquaint Habr's readers with chapters from his book “The Theory of Happiness” with the subtitle “Mathematical foundations of the laws of meanness”. This is not a published popular science book, very informally telling how mathematics allows you to look at the world and life of people with a new degree of awareness. It is for those who are interested in science and for those who are interested in life. And since our life is complex and, by and large, unpredictable, the emphasis in the book is mainly on probability theory and mathematical statistics. Theorems ...

Repost from a third-party Telegram channel (PHP MadelineProto)

 
3r3-31. Having decided to tackle a shameless copy-paste (or rather, its automation) of posts from someone else's Telegram-channel into my own, I first got into the documentation on telegram bots. But as it turned out, bots not only have no methods for receiving messages, they simply cannot be added to another channel.
 
 
The solution was needed in PHP and the next hour was spent searching for it. It's amazing how little information about this is (although no, no wonder who writes this in PHP at all ) 3r339. . In general, the road with StackOverflow resulted in 3r311. MadelineProto

How is jаvascript more convenient than CSS? How does writing CSS inside JS make it more supported?
I would be happy to talk on this topic. I’ll say right away that CSS-in-JS solutions have overhead, but usually this price is justified by the advantages they bring. Sometimes they can be useful, but it also does not mean that CSS-in-JS should be ...

MapStruct solving a problem with ManyToMany

MapStruct solving a problem with ManyToMany  
Hello, dear readers! Those who develop Web applications in Java using the Spring framework, those who comment on these applications and are simply interested.
 
In the previous article 3-333231. "Spring Boot Solving a Problem with ManyToMany"
