🙄Разминка для ума!
Треугольник Серпинского, интересная фигура которую построить достаточно просто.
Алгоритм такой:
1. создаём любые 3 точки на плоскости
2. из этих точек случайно выбираем любую, как начальную
3. случайно выбираем любую точку из этих же трёх точек как цель
4. перемещаемся в сторону цели на половину расстояния
5. повторяем бесконечно с пункта 3
Если сделать достаточно много итераций то вырисовывается интересная фигура. Треугольник, в который вписаны более мелкие треугольники. Это самый настоящий фрактал!
Я собрал пример построения такой фигуры на базе Qt.
🌎 Код можно посмотреть здесь.
С помощью paintEvent я рисую точки по озвученному алгоритму. Каждые 10 секунд либо по клику на виджете строится следующий треугольник.
Особенности примера:
🔸 Атрибут Qt.WA_OpaquePaintEvent позволяет сохранить то, что было нарисовано в прошлой итерации. Таким образом мы видим постепенное наполнение точек а не мелькающую одну точку.
🔸QTimer позволяет создавать отложенные вызовы один раз или с повторением через интервал.
🔸QColor.fromHsv() позволяет создать рандомный но предсказуемый цвет с помощью HSV схемы. Не слишком светлый и не слишком тёмный но всегда с разный. Рандомизации подвергается только смещение по цветовому кругу (Hue), яркость (Value) и насыщенность (Saturation) можно контролировать отдельно в своих пределах или оставить статичными. Обычный рандом цвета по RGB не даёт такой предсказуемый результат.
🔸 Каждый новый цикл с новым треугольником предварительно затемняет предыдущие через этот вызов
painter.fillRect(rec, QColor(0, 0, 0, 100))
То есть полупрозрачный цвет. Таким образом, чем старше треугольник, тем он темней.
Если сделать виджет фулскрин, то у нас получится некий ScreenSaver)))
🔸 Да, я знаю, что рисование в Qt не самый лучший способ сделать этот пример) Скорее всего самый НЕподходящий. Попробуйте сделать тоже самое но другими средствами.

Ethereum Rollback Proposed After Bybit Hack
Arthur Hayes proposes rolling back Ethereum to a block prior to the $1.5B Bybit hack, arguing it would benefit both the platform and holders. He asserts that Ethereum’s immutability can be revisited, citing prior instances. Support for the rollback comes from Bitcoin maximalist Samson Mow, suggesting it could limit funding for North Korea’s nuclear program. The plan involves pausing all ETH trading and renaming the hacked chain to ETHNK. Bybit CEO assures that company assets exceed the lost amount, with significant reserves remaining secure.
