7.09.2025 состоялся релизPithon 3.14! На фоне хайпа про NoGIL всё позабыли про другие фичи. Особенно про Multiple Interpreters, который обещает изоляцию процессов но с эффективностью потоков! На сколько действительно это будет эффективно мы узнаем позже, потому что сейчас это лишь первый релиз с ограничениями и недоработками. Но что там про NoGIL? Теперь этот режим не экспериментальный, а официально поддерживаемый, но опциональный. Чтобы запустить без GIL нужна специальная сборка. И перед стартом нужно объявить переменную PYTHON_GIL=0 Для вас я собрал готовый репозиторий где достаточно запустить скрпит, который всё сделает: ▫️ соберет релизный Python 3.14 в новый Docker-образ ▫️ запустит тесты в контейнере (GIL, NoGIL, MultiInterpreter) ▫️ распечатает результаты Тест очень простой, усложняйте сами) Вот какие результаты у меня: === Running ThreadPoolExecutor GIL ON TOTAL TIME: 45.48 seconds === Running ThreadPoolExecutor GIL OFF TOTAL TIME: 6.14 seconds === Running basic Thread GIL ON TOTAL TIME: 45.54 seconds === Running basic Thread GIL OFF TOTAL TIME: 4.74 seconds === Running with Multi Interpreter TOTAL TIME: 18.30 seconds Если сравнивать GIL и NoGIL, то на мои 32 ядра прирост х7-x10 (почему не х32? 🤷). При этом нам обещают что скорости будут расти с новыми релизами. Режим без GIL похож (визуально) на async, тоже параллельно, тоже не по порядку. Но это не IO! и от того некоторый диссонанс в голове 😵‍💫, нас учили не так! Интересно, что чистый Thread работает быстрей чем ThreadPoolExecutor без GIL. Ну и где-то плачет один адепт мульти-интерпретаторов😭 Теперь нужно искать где они могут пригодиться с такой-то скоростью. Скорее всего своя область применения найдется. Отдельно я затестил память и вот что вышло на 32 потока: ThreadPoolExecutor GIL ON 305.228 MB ThreadPoolExecutor GIL OFF 500.176 MB basic Thread GIL ON 90.668 MB basic Thread GIL OFF 472.444 MB with Multi Interpreter 1267.788 MB Пока не знаю как к этому относиться) В целом - радует направление развития! #release

#Rivers SyrDarya and AmuDarya on the brink: water scarcity is reshaping regional policy The water-energy crisis in Central Asia is becoming one of the key challenges for the region, including Uzbekistan. According to Kassym-Jomart Tokayev, water availability per capita in the region has decreased by nearly 30% over the past 20 years. Climate change is intensifying the pressure: glaciers in the Pamir and Tien Shan mountains, which feed the Amu Darya and Syr Darya rivers, are rapidly melting. An additional source of concern is the construction of the Qosh Tepa Canal in Afghanistan, which could significantly reduce the flow of the Amu Darya and affect water supply in Uzbekistan and Turkmenistan. The situation is further complicated by an outdated water management system inherited from the Soviet era. Previously, a “water-for-energy” mechanism functioned in the region: Kyrgyzstan and Tajikistan stored water in summer for irrigation needs in Uzbekistan, Kazakhstan and Turkmenistan, receiving energy resources in winter in return. After the collapse of the Soviet Union, this system largely broke down. Today the situation is further complicated by large hydropower projects such as Rogun Dam and Kambarata-1 Hydropower Plant. While these projects strengthen the energy independence of upstream countries, they also raise concerns among downstream states, including Uzbekistan. Experts say the region now faces a choice: escalating water conflicts or strengthening cooperation. For Uzbekistan, water is directly linked to food security, agriculture, and environmental stability. One proposed solution is the creation of a new regional mechanism for managing transboundary water resources and the joint implementation of water-saving technologies. Without such cooperation, water scarcity could become a major challenge for the sustainable development of the entire Central Asian region. 💧🌍 ☘️Read the latest environmental news on the @ekologuz page.

#Nature #Rivers Amazon's Meeting of Waters Dual-Toned Rivers of Amazon Experience the mesmerizing natural phenomenon at the 'Meeting of Waters’ near Manaus. Here, the dark Rio Negro and the lighter Amazon River flow in parallel, refusing to mix for miles, creating a stunning dual-toned effect. The surrounding landscape features a prominent plateau and mesa, adding to the dramatic beauty of this unique confluence. The vibrant sunset enhances the contrasting colors of the rivers, making it a truly unforgettable sight. This natural wonder showcases the power and beauty of the Amazon rainforest.

🌍 The world’s shortest river, the Roe River in Montana, flows only about 61 meters from its source to its mouth. Despite its tiny length, it’s officially recognized as a river. ✨ #rivers⚡#hydrology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍 ​

🌎 Deep in the Brazilian rainforest, the Encontro das Águas marks where the dark Rio Negro meets the sandy Amazon River. The two rivers flow side by side for 6 kilometers without mixing due to differences in temperature, speed, and density. ✨ #mysteries⚡#rivers⚡#Brazil 👉subscribe Interesting Planet 👉more Channels ​

🌍 The Amazon River’s water travels over 6,400 kilometers from Andes glaciers to the Atlantic, but some of its rain comes from clouds recycled multiple times through plant evaporation along the journey. ✨ #hydrology⚡#rivers⚡#rainforest⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​

🌍 Rivers in the Amazon basin recycle rainwater so efficiently that a single water droplet may fall as rain and evaporate back into the sky up to seven times before leaving the forest. ✨ #hydrology⚡#rainforest⚡#rivers⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​
