Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• Show the first commit: git log --reverse --max-count=1
• Non-merge commits to master: git rev-list --no-merges master --count
• Number of non-merge commits in master per author: git shortlog -s -n --no-merges master
• Merges to master: git rev-list --merges --first-parent master --count

If you want to see the commits in question, you can replace --count with something like --pretty=oneline.
