First problem: logs aren’t available in the OTel JavaScript SDK. They’re still in development. (It is the end of 2023.) There is … Read moreSending OTLP Logs from JavaScript
When I make a website, even a toy one, I want to get telemetry. Has anyone visited it? Did my JavaScript crash? Little things. I want to send this with OpenTelemetry, because it’s the industry standard and all. Currently (November 2023), that requires a whole JavaScript build chain to package up the libraries etc etc. … Read moreOpenTelemetry in a script tag

Forget diving; I can dip my toe into it with the help of ChatGPT. With its help, I got … Read moreUsing ChatGPT in Anger (not real anger)
Have you ever looked at someone else’s Honeycomb query and thought “what’s up with ‘trace.parent_id does not exist’? Or wondered how Honeycomb’s home screen counts Total Requests? This is totally confusing. Here, I made a video about how to do it and why it works like that.
