In the below keyboard shortcuts, I use the capital letters for reading clarity but this does not imply shift, if shift is needed, I will say shift. So ⌘ + D does not mean hold shift. ⌘ + Shift + D does of course.

Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`

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.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

Note (December 16, 2021): These example files haven't been updated since 2016. In either 2019 or 2020, our onion domain was changed to a longer v3 onion address (p53lf57qovyuvwsc6xnrppyply3vtqm7l6pcobkmyqsiofyeznfu5uqd.onion). The examples below don't reflect this, but the configuration portions remain accurate regarding how we currently serve the onion site. (Tor Browser dropped support for v2 addresses, such as propub3r6espa33w.onion, in the second half of 2021.)

These files contain the base configuration for ProPublica’s Tor hidden service mirror.

Of note:

We're using the nginx "subs_filter" and "headers more" modules to allow us to rewrite content and update headers, so that we can convert clearnet links into onion links, where possible.

Virtual hosts

Let's say you want to host domains first.com and second.com.
