Show HN: Go-Nbd – A Pure Go NBD Server and Client

• go-nbd

  6 330 7.5 Go

  Pure Go NBD server and client library.

You should probably defer mutex unlock() and not use naked returns: https://github.com/pojntfx/go-nbd/blob/main/pkg/backend/file...

• gnet

  6 8,823 8.4 Go

  🚀 gnet is a high-performance, lightweight, non-blocking, event-driven networking framework written in pure Go./ gnet 是一个高性能、轻量级、非阻塞的事件驱动 Go 网络框架。

Since this heavily involves networking, take a look into using gnet [0]. You might find some interesting performance improvements by using that over just net.Conn.

• nbdkit-baddisk-plugin

  1 0 10.0 C

  An nbdkit plugin which fails every read and write.

  

Very cool! I'm curious if you've explored testing error cases yet? Years ago I fooled around with nbdkit and developed a "bad sectors" and "bad disk" plugin and found that the error handling around these scenarios left a little to be desired.

• pyamigadebug

  3 45 4.1 Python

  Framework for abstracting Amiga debuggers and access to AmigaOS libraries and devices. AmigaXfer lives here.

NBD is fairly simple. I wrote a minimal server in Python[0]. It is just a few lines.

• UDPspeeder

  8 4,589 3.3 C++

  A Tunnel which Improves your Network Quality on a High-latency Lossy Link by using Forward Error Correction, possible for All Traffics(TCP/UDP/ICMP)

I just use nbd-server, nbd-client (kernel module nbd). While at home things are fine, when not at home things can get bad unless you use something like UDPspeeder <https://github.com/wangyu-/UDPspeeder> then you just need to deal with slower speeds.

I do backups with borg while connected through ethernet.
