Syncthing Ubuntu/Mint Headless

Syncthing is a free, open-source peer-to-peer file synchronization application available for Windows, Mac, Linux, Android, Solaris, Darwin, and BSD. It can sync files between devices on a local network, or between remote devices over the Internet. Data security and data safety are built into the design of the software.

This is written using Linux Mint 21.2 x86_64 using kernel 5.15.0-89-generic.

I couldn't find good directions for doing this, so here we go.

In case anyone else wants to play with Zig on webassembly, here's what you need to do to make it work on a mac today.

1. Get LLVM 7 compiled with webassembly support.

You'll need LLVM to output to the WASM target. This has just been added by default in trunk, so if LLVM >7 is available, you might be able to just brew install llvm.

If you have wasm support already you should see:

$ llc --version

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
