Regular blog here, 'microblog' there

Many of my traditional blog post live on this site, but a great majority of my social-style posts can be found on my much-busier microbloging site at updates.passthejoe.net. It's busier because my BlogPoster "microblogging" script generates short, Twitter-style posts from the Linux or Windows (or anywhere you can run Ruby with too many Gems) command line, uploads them to the web server and send them out on my Twitter and Mastodon feeds.

I used to post to this blog via scripts and Unix/Linux utilities (curl and Unison) that helped me mirror the files locally and on the server. Since this site recently moved hosts, none of that is set up. I'm just using SFTP and SSH to write posts and manage the site.

Disqus comments are not live just yet because I'm not sure about what I'm going to do for the domain on this site. I'll probably restore the old domain at first just to have some continuity, but for now I like using the "free" domain from this site's new host, NearlyFreeSpeech.net.

Using Fedora Modularity in Fedora 28

Modularity is one of the big new features in Fedora 29, but it's also available in Fedora 28.

What is Modularity? As the project leader says in Fedora Magazine:

Modularity lets us ship different versions of packages on the same Fedora base. This means you no longer need to make your whole OS upgrade decisions based on individual package versions. For example, you can choose Node.js version 8 or version 10, on either Fedora 28 or Fedora 29. Or you can choose between a version of Kubernetes which matches OpenShift Origin, and a module stream which follows the upstream.

I want Node.js 10 instead of v.8, so I figured I'd try it out. I'm still running Fedora 28. I haven't upgraded yet. The upgrade from F27 to F28 didn't go so smoothly that I'm eager to do it just yet.

If you want to try Modularity in F28, it helps to read the docs.

First you have to enable the Modular Repository:

$ sudo dnf install fedora-repos-modular

Then you can check for available modules:

$ dnf module list

I like to live on the edge, so I'm going to install Node.js 11:

$ sudo dnf module install nodejs:11

That worked, and now I have Node.js 11. Remember, read the documentation -- that's how I got this far.
