В фреймворке PyQt (и PySide тоже) часто встречается настройка чего-либо с помощью так называемых флагов.
widget.setWindowFlags(Qt.Window)
Взаимодействие нескольких флагов делается с помощью бинарных (или побитовых) операторов.
Несколько флагов можно указать с помощью оператора "|"
list_item.setFlags(Qt.ItemIsSelectable | Qt.ItemIsEnabled)
исключить флаг из уже имеющегося набора можно так
list_item.setFlags(list_item.flags() ^ Qt.ItemIsEnabled)
Добавить новый флаг к имеющимся можно так
list_item.setFlags(list_item.flags() | Qt.ItemIsEnabled)
А проверка наличия делается так
is_enabled = item.flags() & Qt.ItemIsEnabled > 0
Почему именно так? Всё дело в том как именно работают побитовые операторы. Но об этом в следующем посте.

Super Bowl Ad TRICKING You Into Welcoming Surveillance State!
During the Super Bowl, you may have seen a commercial for #Amazon’s #Ring “Search Party” feature, which uses an emotional lost-dog story to encourage adoption of participation in what amounts to a widespread neighborhood #surveillance net. Jimmy points out that the ad masks #privacy risks tied to AI-driven #cameras, data sharing, and Amazon’s broader surveillance ecosystem, including concerns about opt-out defaults and government access.
He and Americans’ Comedian Kurt Metzger expand the discussion into a broader critique of social media and smart devices as tools of self-surveillance, suggesting public safety and convenience are being used to justify constant monitoring. Ultimately, it frames the commercial as emblematic of a growing surveillance state presented as benevolent technology.
