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.

Ruby's 'insert' method is something I'm definitely going to use

It's not a secret that I'm starting to look into the Ruby programming language. I've got a mess of second-hand books, plus there are plenty of helpful web sites.

I was looking into the gsub method of search/replacing in Ruby when I stumbled across something very useful: the insert method.

I'm sure there are plenty of better ways to do this, but the fact that I can do this and understand it ... that's something.

Here is what I'm talking about. I did it all in the interactive Ruby shell (aka irb) and have revised it because it's even easier to type out than I thought:

irb(main):017:0> phrase = "The quick brown fox jumped over the lazy dog's back"
=> "The quick brown fox jumped over the lazy dog's back"

irb(main):020:0> phrase.insert 0, "<bold>"
=> "<bold>The quick brown fox jumped over the lazy dog's back"

irb(main):024:0> phrase.insert -1, "</bold>"
=> "<bold>The quick brown fox jumped over the lazy dog's back</bold>"
