The Quest Begins (The “Why”) I still remember the first time I tried to make a Go program do two things at once. I had a web scraper that needed to fetch a dozen URLs, parse the HTML, and stash the results in a…
I'd like to tell you this was a one-time lapse. It wasn't. I do it constantly. A JWT to check what's in the payload. A chunk of JSON to pretty-print because the API response came back on one line. A cron expression I…
