This example shows how to have a set of goroutines running concurrently and processing requests. Panics from goroutines are recovered and the worker is restarted. You can download it and run it directly using `go run letitfail.go`
package main
import (
"bufio"
"fmt"
"os"
"time"
)
const numWorkers = 3

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

  • One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
  • A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

  • Unison for file synchronization
  • EncFS for folder encryption
