推荐一篇博客，作者介绍在 DS 项目中写测试。毕竟 ML 的项目测试起来和传统的程序不是太一样，除了最基础的 assert, pytest 这些之外对数据的分布和数据一些统计指标也需要做测试。文中提到的几个工具 Hypothesis 和 Pandera 我都是用过的，Pandera 很好用，也可以原生集成给 Pandas/Koalas（Koalas 也是我配合 PySpark 最常用的 DataFrame 工具）。https://www.peterbaumgartner.com/blog/testing-for-data-science/

Telegram has exploded as a hub for cybercriminals looking to buy, sell and share stolen data and hacking tools, new research shows, as the messaging app emerges as an alternative to the dark web.An investigation by cyber intelligence group Cyberint, together with the Financial Times, found a ballooning network of hackers sharing data leaks on the popular messaging platform, sometimes in channels with tens of thousands of subscribers, lured by its ease of use and light-touch moderation.
The cloud-based messaging platform is also adding Anonymous Group Admins feature. As per Telegram, this feature is being introduced for safer protests. As per the Telegram blog post, users can “Toggle Remain Anonymous in Admin rights to enable Batman mode. The anonymized admin will be hidden in the list of group members, and their messages in the chat will be signed with the group name, similar to channel posts.”
