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

Chrome/Chromium 恢复支持 JPEG-XL 图像 #Chromium 2023 年 Google Chrome 移除了对实验性的 JPEG-XL 图像格式的支持。JPEG-XL 是免专利新的图像格式。Google 此举引发了很多争议，因为 Chrome/Chromium 占据了九成市场份额，它是 Web 标准事实上的仲裁者。到了 2025 年事情有了戏剧性转变。Google 改变了主意，开始恢复对 JPEG-XL 图像的支持，去年 12 月 Chrome/Chromium 代码库合并了 Rust 语言开发的 JPEG-XL 图像解码器 jxl-rs，本周基于 jxl-rs 的 JPEG-XL 图像解码功能默认启用。 https://www.phoronix.com/news/JPEG-XL-Returns-Chrome-Chromium https://github.com/chromium/chromium/commit/8215ebd5eb9d45b42bbc68e1ceff039a319b35d6

Chromium 重新设计代码大幅减少 DNS 流量 2021-02-05 23:24#Chromium 去年 8 月，亚太互联网络信息中心（APNIC）报告，Chromium 浏览器中检查网络是否存在 NXDOMAIN 拦截的代码会导致大量的垃圾 DNS 查询流量。NXDOMAIN 是域名错误信息，部分 ISP 会对其进行拦截重定向。Chromium 采用的方法是每次启动、每次 IP 地址变化、每次设备 DNS 配置变更时对 3 个随机的 10 个字符长的字符串进行 DNS 查询。APNIC 称 root 服务器一半的查询流量来自于 Chromium 的检查。这相当于每天在 root 服务器系统查询 600 亿次。APNIC 现在报告，Chromium 团队重新设计了代码停止了垃圾 DNS 查询，这一变动包含在 Chromium 87 中。在 Chromium 87 释出前，root 服务器的峰值查询流量高达每天 1430 亿次，释出后降至了每天 840 亿次，减少了 41%。

📰Raspberry Pi owners are missing this one free tweak that changes everything A couple of years ago, when I was working on my Raspberry Pi 5, I noticed that it was very slow. I googled possible reasons, and the main one was its lack of RAM. It has 4 gigs of RAM, but I noticed that running multiple Chromium tabs made it run at a snail's pace. So, I looked for ways to increase the RAM. Given that I was using an SD Card as a hard drive, using a swap file wasn't really an option. However, I found a program called ZRAM and... 🔗 Source: https://www.xda-developers.com/free-tweak-old-pi-changes-everything/ #chromium#raspberry
