Go 1.22 gave the standard library method-aware routing and path wildcards. Here is how PathValue, precedence, and {$} actually behave.
Gabriel Anhaiadatabase/sql in Go: NullString, Contexts, and Connection Lifecycle
The three database/sql habits that separate a Go service that survives a traffic spike from one that pools out: sql.Null types, QueryContext, and pool tuning.

MarshalJSON, UnmarshalJSON, and the omitempty rules that surprise Go developers: zero values, nested structs, and the pointer-vs-value call.
Gabriel AnhaiaBuffered vs Unbuffered Channels in Go: How the Size Changes Behavior
In Go, a channel's buffer size is not a tuning knob. It changes what the channel means. Here is when to use each, and why a buffer of 1 is a signal.
Gabriel Anhaiajson.RawMessage in Go: Deferring Decode Until You Know the Type
Decode polymorphic JSON in Go without interface{} soup. Read a discriminator field first, then unmarshal the payload into the right struct.
Gabriel Anhaiatime.Ticker and time.Timer in Go: The Reset and Leak Traps
Stop your tickers, stop leaking time.After in loops, and learn why Go 1.23 quietly deleted the drain-before-Reset dance.
