nasnimal @ Habr 1 place · 08/15/2022 03:43 EDT

On average, online store users make 64 clicks before adding a product to the cart. Some clicks are useful - so-called discovery clicks that help lead to users finding a product they wish to buy, and some are useless that come as the result of poor UX. With great competition for convenience and increasingly reducing attention spans of users, each useless click reduces the number of visitors that will reach... Read more ›

temujin @ Habr 2 place · 08/10/2022 05:00 EDT

Сетевой стек TCP/IP не в одночасье стал паутиной, соединившей интернет от края до края. Вся система развивалась довольно бурно, противоречиво, но в целом через инкрементальные усовершенствования в разных местах. Не было какого-то единого плана создания глобальной коммуникационной сети и подходящего под эти цели стека протоколов. Из-за этого вместо сферической семиэтажной OSI в вакууме в наличие у нас есть причудливое смешение технологий и протоколов, где стандарты, написанные в 1970-х всё ещё... Read more ›

Once the Teacher asked the Author:Are there methods of redundancy introducing at an informational level, other than those that are studied by the theory of error-correcting codes? Emphasizing that he is talking about information redundancy, the Teacher thus made it clear that the question does not imply various ways of energy redundancy introducing, which are well studied in communication theory.

How abortion in the age of surveillance capitalism turns Internet into a dystopia

Advertone @ Habr 1 place · 07/31/2022 07:15 EDT

Но в реальности дела обстоят иначе. Достаточно не сидеть сложа руки и пользоваться возможностями, которые появляются на пути.Мы поговорили с разработчиками, которые живут в небольших городах и посёлках, о том, как не дать себе замкнуться в рамках своего...
