Emmet extension for Panic Nova

Someday I need to write about Nova, the code editor from Panic that I use for web development. In the meantime, let me instead tell you about an extension for Nova that I just installed tonight which I knew about from Visual Studio Code.

It’s called Emmet.

Emmet lets you use shorthand to quickly enter html tags and css rules.

If you use Nova for web development, install Emmet. As Tim Cook would say, we think you’ll love it.

SSH Key Creation

Now that you know that SSH keys are about authentication and not session encryption, and that they let you disable password logins on your server, you may be excited about getting to work using SSH keys with your server. There are just two things that can stop you:

  1. You have no SSH keys.
  2. Your server doesn’t know your (as of yet non-existent) public key.

Fortunately, we can solve both of these problems without too much suffering. Today we’ll solve problem one and generate ourselves some SSH keys.

As always, I am writing from the perspective of a person using a Mac or iOS device, and working on Linux servers. If you are running Windows or Linux on your local computer, you’ll have to google elsewhere. Today I’m just going to show how to generate keys on the Mac. Later sometime I’ll show you some iOS and iPadOS apps that can generate or transfer keys for you. …

SSH Key Theory – A Simple Primer

Time is a fluid concept these days, but approximately 25 years or one week ago, I wrote about SSH and what is it good for. The bottom line is that SSH itself is very simple, and there’s not a lot of exciting dramatization that can be produced around its actual use unless you’re really into weird incantations like “ss -pant | grep ‘ESTAB’”. And let’s face it, no one is. You do have to enjoy the fact that we can shove the word “pant” into a perfectly valid Unix command though.

However, there is something directly related to SSH that we should talk about, primarily because it will give me an excuse to write exactly 255 posts about it, and that is the topic of SSH keys.

When you think of a key, you probably think of something that unlocks something else, and that’s exactly what SSH keys are used for. Although SSH keys …
