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!

🚀 Japanese Companies Face Challenges Amid Rising Oil Prices
Japanese companies are entering the earnings season with a pessimistic outlook as crude oil prices surge following the unsuccessful U.S. peace talks with Iran. Bloomberg posted on X, highlighting the impact of geopolitical tensions on the global oil market. The failure of negotiations has led to increased uncertainty, affecting various sectors in Japan that rely heavily on energy imports. As oil prices climb, businesses are bracing for higher operational costs, which could impact their profitability in the coming months. The situation underscores the interconnectedness of global events and their influence on national economies.

🙊 “On.. went.. on..” – we are learning to distinguish swear words from terms from the crypto world!
Cryptocurrencies are an unusual and challenging market. Over the years, Cryptans have invented many words to describe what is happening around them. And we have compiled a dictionary of the most important of them for you:
➖#Wallets are a key vault for different cryptocurrencies. There is no crypt on the wallet itself, it is located in the blockchain and is assigned to your addresses. Wallets can be "cold" and "hot".
➖#DeFi – decentralized finance. Such crypto projects do not have a specific “manager” or “supervisor”. Interactions between users are managed by smart contracts.
➖#Smart contract - algorithms in the blockchain that control user actions and execute commands and conditions embedded in them.
➖#Proof-of-Work (POW, proof of work) is an algorithm for confirming transactions in the blockchain (achieving consensus) using the computing power of its participants (mining)
➖#Proof-of-Stake (POS, proof of stake) – all transactions in the blockchain are confirmed using cryptocurrency in the wallets of participants
➖#Staking – placement of POS-blockchain tokens in a wallet for a reward. The POS system needs coins to function. A more convenient and effective form is liquid staking.
➖#Gas – payment for transactions on the blockchain. When the activity on the network increases, so does the gas charge.
➖#Fork – updating/changing the blockchain: its technologies and rules
➖#Mixers are platforms that mix tokens of different users, hiding the history of transactions and previous owners.
➖#Bridges (cryptomostes, cross-chain bridges) is a service for transferring crypts from one blockchain to another. Without them, different blockchains and crypto projects cannot communicate with each other.
➖#NFT is a unique digital certificate confirming the ownership of a digital object: anything, but most often a song, a picture, an object from a game.
➖#Stablecoins are coins backed by reliable real assets (dollars, government bonds), and therefore stable in price: 1 to 1 with the dollar.
➖#Memcoins are often coins created “for fun". They are popular among speculators, but some coins “grow up” and try to create full-fledged projects.
➖#Profitability farming is earning money by providing your tokens for trading to other users in liquidity pools on a decentralized crypto exchange.
➖#Airdrop – free distribution of crypto project coins for user activity: try out the project, tell about it on social networks

Disrupting Subscription Models
A potential billion-dollar startup aims to revolutionize content sales by eliminating subscription models that frustrate users wanting single purchases. Currently, 70% of subscribers cancel within 3-6 months, while content sellers hesitate to switch to one-time payments due to lower profitability. Innovations in this direction could lead to significant market changes. More details here: Fast Founder
