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.

The AI Memory Problem Nobody's Solving
Every AI conversation starts from zero, creating a digital dementia crisis where your data is rented, not owned. While the tools for persistent memory exist, billion-dollar giants prefer selling subscriptions to walled gardens over giving you actual agency.

November 20, 2025
The internet is blinking across the world and experts say this may be the start of one of the largest global outages in recent years.
🚨 WHAT’S HAPPENING RIGHT NOW

• Cloudflare — one of the biggest internet infrastructure providers — suffered a massive failure
• Millions of users across multiple countries reported errors within minutes
• Websites, apps, and even essential online services are showing instability
• Some regions are seeing partial blackouts and slowdowns
This isn’t just one website failing…

• Banking portals
• E-commerce
• Streaming
• Messaging apps
• Business platforms
Everything becomes vulnerable.
⚡️ IS A MAJOR OUTAGE COMING?
Many experts say YES the signs are there.
The internet has never been more interconnected…
And that means when one piece breaks, the whole system feels it.
💬 STAY PREPARED:
• Screenshot important info
• Keep offline copies of documents
• Download maps & essential contacts
• Expect slowdowns, login errors, and random crashes
• Don’t panic — stay informed
🌍 This story is still developing.
If the global network weakens further, the next few hours could get rough.
