本文基于前作《若将Git历史视为SQL数据库会怎样？》中介绍的pgit系统展开。新读者建议先阅读前作。核心概念：pgit是仿Git命令行工具，将所有数据存储于PostgreSQL而非文件系统，采用pg-xpatch实现透明差值压缩，支持通过SQL查询完整提交历史。前作登上HN头条并被多家技术媒体转载后，我曾预告将进行Linux内核导入实验，现将完整过程呈现如下。
This isn’t because there’s no way to secure CAN communications, mind you. A strong implementation (and in fact, the industry standard) would involve two CAN security features, in addition to the implementation of firmware-level unique keys and ECDSA/RSA firmware signing. UDS Service 0x29 (introduced in ISO 14229-1:2020) uses asymmetric PKI-based certificate exchange for user authentication, and AUTOSAR SecOC for per-message authentication and freshness validation, preventing replay attacks. While these modifications would add some additional time to the firmware write operations, the Arm Cortex-M4 core included in the ECU’s XMC4500 is very efficient at cryptographic functions and the total delta would likely be only about 6 seconds.4 5 6，这一点在汽水音乐中也有详细论述
