The Collatz conjecture is the coolest math trick of all time

On the Internet and in non-fiction literature you can often find various mathematical tricks. The Collatz conjecture leaves all such tricks behind. At first glance, it may seem like some kind of a trick with a catch. However, there is no catch: https://bit.ly/3n9FSjo

As developers, we spend a significant amount of time in the terminal, executing commands, writing scripts, and trying to solve problems. But, how many times have you found yourself stuck, trying to remember the correct syntax or flag for a command, or spending hours looking for a specific code snippet?

"Wi-Fi looks like a very complicated thing standardized over hundreds of pages. Could a non-expert with a PC and a couple of 100$ devices (HackRFs) somehow improve it? Here I try to develop a Wi-Fi optimization approach basically agnostic of protocol implementation details. There's some math and Python programming in it"

Array of weak in Swift

In Swift, when working with objects, it’s important to manage memory correctly. One way to do this is by using weak references to avoid retaining objects too long and causing memory leaks. In this article, we will discuss how to create an array of weak references in Swift using a generic wrapper: https://bit.ly/42Z6bJq

Langton's ant: a mystery cellular automaton

There are about 14,000 species of ants on Earth, each of them has its own name. However, no matter how hard you try, you will not find Langton's ant in any biological encyclopedia.

The thing is, Langton's ant is just a mathematical abstraction, a model for describing the behavior of a dynamic system. Sometimes it seems that mathematicians are really fascinated with ants — just to mention, the ant colony optimization algorithm that has already become a classic. Also, ants are quite common in all sorts of logical models and math problems: https://bit.ly/3Ks3zfL
