# Toggle all currently 'Active' network servcies (e.g., Wi-Fi, Ethernet
# connections, etc...) to "restart" them. We'll ignore any already 'Disabled'
# services, and toggle all of the others to 'Disabled' and then back to
# 'Enabled'. This has been found helpful when your VPN won't re-connect after
# undocking and re-docking your MacBook, for example.

Searching Git commit history

This should be one of the core features of Git, but for some reason it's impossible to figure out how to search for a string in your commit history and see the diffs that that string is in. Here's the best I've come up with:

To find which commits and which files a string was added or removed in:

git log -S'search string' --oneline --name-status

To see the diff of that

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

Solution

This solution fixes the error caused by trying to run npm update npm -g. Once you're finished, you also won't need to use sudo to install npm modules globally.

Before you start, make a note of any globally installed npm packages. These instructions will have you remove all of those packages. After you're finished you'll need to re-install them.
