#22Earlier quoted context omitted.
Just on HN alone I think I've seen roughly 3948538902748750897520938 mentions of emdashes when others were complaining about slop in the past 2 months. It might as well be the unofficial slop logo. Folks are treating it like a dead giveaway. I feel like a school friend of mine has been taken from me.
It’s just people who don’t read books outing themselves. Ignore.

#23> The agent surfaced a suspicious issue: the anetd pods in our Google Kubernetes Engine cluster were restarting constantly, around 120 restarts per pod over six days, which is almost one crash per hour. Surely, this couldn't be right!
> Sascha dug into the crash dumps. The stack trace pointed to a concurrent map-access panic, multiple goroutines trying to read and write to the same data structure at the same time without proper locking. But the key detail was where the panic happened: inside the Wireguard module of anetd.
AI: Your anted pod is crashing.
Engineer: Looks in the logs and finds a stack trace.
Your agent didn't find the bug. It's really that simple.

#25There may be some good answers and lessons, but they didn’t make it into the article. Saying it’s on a cloud provider’s private network so encryption between your nodes isn’t necessary is a bold choice. Also, what happened to the root cause? Why did it start failing a week ago? Was a downgrade of the offending code not possible?
Not all bug investigations are worth really digging into. Sometimes the right call is to find any fix and move on. But all the nuance, judgement, implications, and lessons learned failed to make it into this post. And they are what make reading incident reports interesting for most engineers.

#26I think the credit belongs to Sascha still.

I felt like this with the word delve. Seemed like nobody had ever heard the word before, and that the only possible way it’d be written was if an llm did it - but it’s just a nice word.
the premiere golang debugger is called delve. Also you must not hang out w/ many ttrpgers.

this is person right? not a agent... and this whole article seems like it was written by AI...

#30This piece might be a record for how quick it took me to smell the AI-tone and close the tab.. one paragraph! I'm sure it's an interesting bug but I can't stomach reading any more slop.
