One stupid thing you can do: have an ack deadline for a pub/sub msg that's shorter than the time it takes your service to process it
You'll ddos your own service, be confused for a bit, and then just feel like a silly goose
Or I suspect that is what would happen. I would never do that of course...

It drives me crazy that both dropbox and google drive fail silently if you try to download a folder with too many files. Both will literally give you zip with the first "x" amount of the data downloaded and say nothing...

I think clothing companies are beginning to overcorrect for the “women’s clothes never have pockets” issue - Maddy’s clothes now all have like 6 pockets - she just got a hiking shirt and found a “secret” pocket in it lol

South Park was one of the first shows that I wasn’t allowed to watch growing up - which meant I would naturally find ways to watch it at friends houses, etc.
Haven’t seen a lot of the newer episodes except the most recent - but love this for them
