I just sent out the latest edition of the newsletter version of this blog. It’s a long one! Turns out I wrote a lot of stuff in the past 10 days.
The newsletter is out two days later than I had planned because I kept running into an infuriating issue with Substack: it would refuse to save my content with a "Network error" and "Not saved" and I couldn’t figure out why.

I just sent out the latest edition of the newsletter version of this blog. It’s a long one! Turns out I wrote a lot of stuff in the past 10 days.
The newsletter is out two days later than I had planned because I kept running into an infuriating issue with Substack: it would refuse to save my content with a "Network error" and "Not saved" and I couldn’t figure out why.
So I asked ChatGPT to dig into it, which dug up this Hacker News post about the string /etc/hosts triggering an error.
And yeah, it turns out my newsletter included this post describing a SQL injection attack against ClickHouse and PostgreSQL which included the full exploit that was used.
Deleting that annotated example exploit allowed me to send the letter!
