Show HN: A microblog hosted in DNS TXT records

that's cool but what are you using to create these on the go?

It is currently a manual process.

This first entry I made by

    TZ=UTC echo $( date +%YT%T%z ). 

Which I copied to my clipboard and then manually created the TXT record for and then the CNAME.

Next time I want to add an entry, I will:

    expr $( host head.microblog.erikano.net \
            | egrep -o '[^ ]*$' | cut -d'.' -f1 ) + 1

To get the ID for the post to be made and then echo calling date as I did for the first post.

Had I still been hosting the DNS server myself, I would've turned this into a script and appended the entry as a TXT record directly and updated the CNAME to the new value using sed.

Actually, thank you for asking because I just realized what my next little project should be: Instead of the way I'm doing it now, I can selfhost a little DNS server which will be authorative over microblog.erikano.net while still hosting the DNS for the rest of erikano.net and my other domains where I have them now. The project will be written in Go since I have been wanting to make something in Go but didn't finish the other things I started writing in Go. I have no ETA for the microblog DNS selfhost server project because of work and current projects.

Hope I didn't misunderstand the question but if I did and you meant how to update the microblog when I'm out and about, the answer is I would need to use a web browser currently to manually update the records. When my own server has been written, I simply ssh to my VPS which hosts the server and run a cli tool I will name "mb" ("microblog") with my message as argument.
