Awesome. Thanks for sharing.
I thought the post was timely since the alert triggered today. The ntfy server was DDoS'd today and I got alerted pretty much instantly. It was quite nice.
Except that you can selfhost both healthchecks.io and ntfy.sh; and you can't selfhost reddit or any of the services they advertise, haha
I know you specifically asked for books, videos and podcasts, but I have actually personally never found any books, videos or podcasts I tried super inspiring or helpful. The only thing I have done on occasion is to use Pluralsight courses to learn a particular language or platform really fast (Android development, React, ...).
What I can really recommend though is to just read Hacker News and get inspired by what other people do. I find only about 10% or so actually interesting, but there's always something fascinating.
Aside from that, I learned most of my programming knowledge (not necessarily engineering knowledge) from side projects. For about a year now I have worked on a push notification service called ntfy that truly fulfills me, and that forces me to constantly learn new things.
Thank you for the insight. Fascinating. Also insane that ever upvote causes a flood of messages being distributed...
