发现一个非常好用的 Obsidian 插件：https://github.com/RyotaUshio/obsidian-pdf-plus
通过 backlink 实现不出 Obsidian 就能给 PDF 做标注和笔记，并且笔记还可以分散在多个文件中，设计得相当 Obsidian native。

Telegram is a free app and runs on donations. According to a blog on the telegram: We believe in fast and secure messaging that is also 100% free. Pavel Durov, who shares our vision, supplied Telegram with a generous donation, so we have quite enough money for the time being. If Telegram runs out, we will introduce non-essential paid options to support the infrastructure and finance developer salaries. But making profits will never be an end-goal for Telegram.
Launched in 2013, Telegram allows users to broadcast messages to a following via “channels”, or create public and private groups that are simple for others to access. Users can also send and receive large data files, including text and zip files, directly via the app.The platform said it has more than 500m active users, and topped 1bn downloads in August, according to data from SensorTower.Parallel Experiments from id
