I really liked the Agile Web Development with Rails book.
Indieweb Summit 2019 Thoughts

Thanks to Aaron Parecki, the Indieweb Summit 2019 videos have been posted to the Internet Archive which includes the day 1 keynotes, intros and sessions and the day 2 sessions and demos.
I really enjoyed the teamwork of the Possible Futures session as we broke out into 4 groups and our group had the opportunity to discuss surveillance capitalism. I also enjoyed talking with Johannes Ernst about the latest plans for UBOSbox. I also attended the AutoAuth session but private posts, although important, donβt seem like a natural fit with Indieweb building blocks to me. I could be wrong. After day 1, some of us attended Dat night which was great.
There were a lot of good day 2 demos. Displaying a live list of sites you subscribe to with your reader which was done by Jonathan Lacour looked great. For my demo, I made this site available on the Dat network which you can access with Beaker browser at dat://herestomwiththeweather.com. I have installed a Dat service on my rackspace server which will keep a copy of my site on the Dat network:
$ dat store dat://b8ffbddeac2c7eec8b60f1d33774f515f47affe4bef0ad6fec15bc0c6cb1ad78
Indieweb Summit seemed even better organized this year and I mentioned some of what I considered improvements at Austin Homebrew Website Club this week for consideration at the next IndiewebCamp Austin.
