Lightning network in depth, part 1: payment channels

Lightning network is a decentralized off-cheking technology that allows you to conduct tens of thousands of transactions per second, as it allows, for example, Visa. At the moment Bitcoin is the most popular crypto currency in the world, it is not adapted to send more than ~ 7 transactions per second, and high fees and long confirmation time nullify the possibility of sending microtransactions.
Lightning network solves both of these problems

Women in IT, a look from the inside

Women in IT, a look from the insideI work in the IT field after Baumanka's completion for the fourth year and during this time I went from the production department engineer to the project manager. It's no secret that the share of women in IT is small. In our company, for example, the girls are exactly one third. Why do so few girls choose this area for themselves?
 
 
During my studies at the university and in the first year of work, I was tormented by many doubts, but whether I was exactly in my place. Unfortunately, there are stereotypes and prejudices about girls in the IT sphere, which is probably why there are fewer men than ...
