// This is a "rough sketch" pulled from our application that shows how we use
// RxBluetoothKit and Nordic's DFU library together.  It's more than
// pseudocode, yet not standalone, rigorously tested running code.  A lot of
// details are simplified or omitted here, e.g.  any device-specific details
// you may require, implementations for Nordic's DFU delegate protcols, etc.

Firebase Environments

At the time of writing this gist (January 4th, 2017), I was unable to find true sandboxing to separate development and production environments for a Firebase project. The closest we can get is to create two separate Firebase projects -- one for development and one for production.

Pros

• Complete separation and isolation of all Firebase features.
• Freedom to experiment without risking the corruption of production data.

Cons

• There is no way to copy production data to your development project (that I am aware of).
• Any settings changes made to your development project also needs to be manually applied to your production project.

  // Overwrites the ArraySlice region with the passed-in array of bytes

    var fromIter = from.makeIterator()
    self.withUnsafeMutableBytes { bytes in
      for i in stride(from: bytes.startIndex, to: bytes.endIndex - 1, by: 1) {
        if let fromByte = fromIter.next() {
          bytes[i] = fromByte

# This is a utility wrapper around git update-index used to mark, unmark, and
# list files that are marked with the assume-unchanged bit.  See `git help
# update-index` for details.
#
# Usage:
#   git embargo <FILE>    # Mark a file as embargoed -- changes won't appear in status
#   git embargo -r <FILE> # Remove the embargo
#   git embargo -l|--list # List all embargoed files
