Code snippet: // Dividing int by float doesn't give always same results fmt.Println(15/4.) // = 3.75 a := 15 fmt.Println(a/4.) // = 3 b := 4. fmt.Println(a/b) // err: invalid operation: mismatched types int and float64 fmt.Println(a/4.1) // err: (untyped float constant) truncated to int

Fun fact: be careful when you do mathematical operations on different number types in Go. Sometimes you end up with truncated float, sometimes it panics, sometimes you get the right result 🤷‍♂️

All you need is Wide Events, not “Metrics, Logs and Traces” This quote from Charity Majors is probably the best summary of the current state of observability in the tech industry - a total, mass confusion.

There have been some good posts on what "wide events" instrumentation is but not as many on how to go about it, what attributes you should add, or how to work with OpenTelemetry
