Everything I googled in a week as a senior software engineer
I found this great post while perusing random Bring Back Blogs for new feeds to follow. The conceit is simple, a list of all the mundane things Sophie Koonin (aka localghost) looked up in a week in her. Sharing with the aim of humanizing the profession. It's okay if you look things up, particularly when things are new, don't sweat it.
You aren't expected to know everything no matter your level of "seniority". But worth noting, to stand out it's a good habit to memorize what you use often, and keep some kind of note on less frequent knowledge. I promise over time this practice will increase your efficiency and keep you in flow. Nothing more frustrating than an hour (or more...) of random searches to find that "thing" you sort-of remember seeing once.
