Using F2FS file system in raspi

F2FS (Flash-Friendly File System) is a flash file system initially developed by Samsung Electronics for the Linux kernel.
The motive for F2FS was to build a file system that, from the start, takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks, eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.

Shadosocks Usage

Shadowsocks is a free and open-source encrypted proxy project, widely used in mainland China to circumvent Internet censorship. It was created in 2012 by a Chinese programmer named “clowwindy”, and multiple implementations of the protocol have been made available since. Typically, the client software will open a socks5 proxy on the machine it is running, which internet traffic can then be directed towards, similarly to an SSH tunnel. Unlike an SSH tunnel, shadowsocks can also proxy UDP traffic.
