The reverse is true as well. I traveled in India with a friend from China who used their Chinese sim card in India, and their data was censored through the firewall. Really annoying to be outside China and not able to use Google maps.
Railscasts taught me so much when I was first learning web development right out of university. I used to watch Railscasts episodes religiously when they came out. I don't know if I would have grown as much as a developer without being exposed to the whole ecosystem of tools and techniques that Railscasts presented - I'd often discover libraries existed that solved problems I would never have known to seek out otherwise. Thank you for the time and effort over the years producing the episodes @rbates! Looking forward to hearing the full story in the next installments!
I updated the post to note Thompson Sampling and added a note about using only recent data as a potential improvement and linked to this comment. Thanks for this note!
Can confirm, using a non-root user also solves the issue (which I should have been doing anyway). It guess Cloud Run assumes $HOME is set to /home/something and since root uses /root it gets confused?
