• If your Jest tests are hanging indefinitely, it might be a render loop caused by lazy and state/observable updates
  • 'maybe' being the operative word, I still don't properly understand why that was happening
  • but the actual behaviour was never broken and removing lazy fixed it after hours of wall head-butting, so I'll take it
• Honeycomb does not let you have an SLO covering two separate endpoints, e.g. comparing the successful requests for OTPs to successful uses
  • Seems like a useful feature for... pretty much everything
  • There are a lot of cases where you want compare the generation of something and its use
  • But ended up having to create two separate SLOs, one for the error rate of each endpoint
  • Which isn't really measuring the right thing
