A git repository is a content-addressable object store where objects go in indexed by the SHA1 of their content, plus a set of named references pointing at specific objects by hash. The on-disk format (loose objects as individual files, packfiles as delta-compressed archives with a separate index, a ref store split between a directory of files and a packed-refs flat file with a locking protocol that breaks on NFS) is an implementation detail. The protocol for synchronising objects and refs between repositories is what actually matters, and since git-the-program is just one implementation of it, you can swap the storage backend without clients noticing.，这一点在91视频中也有详细论述
But some question whether this expensive technology is worth it.
Code runs in a completely separate, hardware-backed environment with its own guest kernel. It is important to separate the concepts here. The hypervisor is the capability built into the Linux kernel that manages the CPU’s hardware virtualization extensions. The Virtual Machine Monitor is a user-space process that configures the VM, allocates memory, and emulates minimal hardware devices. The microVM itself is a VM that has been stripped of legacy PC cruft so it boots in milliseconds and uses minimal memory.，这一点在Line官方版本下载中也有详细论述
