Использование Pydantic сегодня стало нормой, и это правильно. Но иногда на ревью вижу, что используют его не всегда корректно. Например, метод BaseModel.model_dump() по умолчанию не преобразует стандартные типы, такие как datetime, UUID или Decimal, в простой сериализуемый для JSON вид. Тогда пишут кастмоный сериализатор для этих типов чтобы функция json.dump() не падала с ошибкой. import uuid from datetime import datetime from decimal import Decimal from uuid import UUID from pydantic import BaseModel class MyModel(BaseModel): id: UUID date: datetime value: Decimal obj = MyModel( id=uuid.uuid4(), date=datetime.now(), value='1.23' ) print(obj.model_dump()) # не подходит для json.dump # { # 'id': UUID('4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1'), # 'date': datetime.datetime(2025, 12, 12, 12, 12, 12, 111111), # 'value': Decimal('1.23') # } # добавляем свой кастомный сериализатор json.dumps(obj.model_dump(), cls=MySerializer) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2025-12-12T12:12:12.111111', # 'value': '1.23' # } В данном случае класс MySerializer обрабатывает datetime, UUID и Decimal. Например так: class MySerializer(json.JSONEncoder): def default(self, o): if isinstance(o, Decimal): return str(o) elif isinstance(o, datetime): return o.isoformat() elif isinstance(o, UUID): return str(o) return super().default(o) Специально для тех, кто всё еще так делает - в этом нет необходимости! Pydantic может это сделать сам, просто нужно добавить параметр mode="json". json.dumps(obj.model_dump(mode="json")) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2012-12-12T12:12:12.111111', # 'value': '1.23' # } #pydantic#libs

👀 India, Indonesia and Mexico are the most promising countries for cryptocurrency adoption. This conclusion was made by researchers at the venture capital firm Jump Capital based on the following factors: ▫️ the risk of high inflation / currency instability; ▫️ large flows of remittances; ▫️ immature financial infrastructure / lack of trust in banks; ▫️population; ▫️ the ratio of GDP / national wealth; ▫️ gold reserves; ▫️regulatory and banking environment; ▫️ a tendency to speculation (exchange trading, gambling, etc.). #cryptocurrencies#research

Haveno https://github.com/haveno-dex/haveno Private and decentralized way to #exchange#Monero for national currencies or other #cryptocurrencies. Haveno uses peer-to-peer networking and multi-signature escrow to facilitate trading without a trusted third party custodian. Disputes can be resolved using non-custodial arbitration. Everything is built around Monero and Tor. Haveno is the Esperanto word for "Harbor". The project is stewarded by a core Team, currently formed by 2 people: ErCiccione and Woodser. See the FAQ in the wiki for more information about the project https://github.com/haveno-dex/haveno/wiki/FAQ Haveno is still work in progress. There are no binaries available at this stage. If you want to test Haveno you have to compile it first (see https://github.com/haveno-dex/haveno/blob/master/docs/installing.md). Status of the project At the moment Haveno is only a Proof of Concept. It's already possible to initiate crypto <-> XMR and fiat <-> XMR trades, but the platform still needs a lot of work before being available for public use.

⚠️#Google here gave the holder of #cryptocurrencies a dose of anxiety with the news that quantum computers will be able to hack the military-technical cooperation network much earlier than current forecasts. ⚠️ To #crack RSA encryption, you need 20 times less resources than expected (less than 1 million qubits). Modern quantum computers are much weaker, but their power is constantly progressing. According to various forecasts, it will be possible to cross the 1 million cubic meter mark after 2030.👀
