Routing tips for VPNs on OS X

When VPNs Just Work™, they're a fantastic way of allowing access to a private network from remote locations. When they don't work it can be an experience in frustration. I've had situations where I can connect to a VPN from my Mac, but various networking situations cause routing conflicts. Here are a couple of cases and how I've been able to get around them.

Specific cases

Case 1: conflicting additional routes.

In this example the VPN we are connecting to has a subnet that does not conflict with our local IP, but has additional routes that conflict in some way with our local network's routing. In my example the remote subnet is 10.0.x.0/24, my local subnet is 10.0.y.0/24, and the conflicting route is Without the later route, I can't access all hosts on the VPN without manually adding the route after connecting to the VPN:

A function to find the offsets of newlines ('\n') in UTF-16 encoded string. Try as I might, I cannot get a Swift version within an order of magnitude of the C++ version. Both routines must return arrays of the same size and with equal elements.
#import <Foundation/Foundation.h>
#import <QuartzCore/QuartzCore.h>
#import <iostream>
#import <vector> // Needed for gist to compile.
#pragma mark - Pure Implementation Functions
const static unichar kUTF16Newline = (unichar)'\n'; // old naming habits die hard!
* Calculates an array of line end "positions" for a given string.
* The equivalent Swift function was `(String) -> [Int]` or `(NSString) -> [Int]`

<!-- iOS 10, macOS Sierra, and friends bring a new logging subsystem that's
supposed to scale from the kernel, up to frameworks, and up to apps. It defaults
to a more regimented, privacy-focused approach that large apps and complex
systems need.
It, along with Activity Tracing introduced in iOS 8 and macOS Yosemite and the
Console app in macOS Sierra, hope to help you graduate from caveman debugging to
