Facebook 发布了 OpenZL，一个可以通过学习文件格式的结构同时优化压缩率、压缩速度、解压速度的算法。
在使用时，程序员可以编写对于文件结构的描述，并生成/训练特定于这一文件格式的压缩算法，使得可以通过文件本身内部结构生成更容易压缩的数据流。所有这些压缩后的数据流都可以共享同一个解压算法，压缩算法改变时不需要修改。当输入无特定结构时，算法回退到 zstd。

Introducing OpenZL: An Open Source Format-Aware Compression Framework
OpenZL is a new open source data compression framework that offers lossless compression for structured data. OpenZL is designed to offer the performance of a format-specific compressor with the eas…

这个设计其实让咱想到了之前 DBinary 在知乎上发的一篇文章：
https://www.zhihu.com/question/653305534/answer/3474839964
思路是类似的，都是用数据中隐含的结构和领域特定知识提升压缩率，但是 fb 把整个设计通用化了（因为是大公司，需要支持各种产品线）

Orcas are bringing humans gifts – what does it mean?
Researchers have documented orcas seemingly gifting rays, seals and fish to scientists and divers, which could suggest they have theory of mind and engage in altruism – even across species

SpaceX Starship 第十一次发射将于北京时间 2025-10-14 07:15 (美中时间 2025-10-13 18:15) 左右进行，窗口时长未知。本次发射将大致重复 Flight 10 的飞行轨迹和计划，在印度洋溅落二级，在墨西哥湾溅落一级。 https://fixupx.com/SpaceX/status/1972798064403357887 官网：https://www.spacex.com/launches/starship-flight-11 直播：https://x.co…
