Advantages of monolithic version control
Someone : Did you hear that Facebook/Google uses a giant monorepo? WTF! Me : Yeah! It's really convenient, don't you think? Someone : That's THE MOST RIDICULOUS THING I've ever heard.

Removing Next.js Got My Blog to 100 on Every Lighthouse Category
My blog just scored a perfect 100 on every Lighthouse category. I love blogging.

Whatever works for you
In my earlier 20s when I knew everything, I was a much bigger evangelist for my technology choices. I’m accused of fanboyism a lot more these days, but only because Hacker News keeps sending huge waves of people here who tell me I’m an idiot. But I used to be much more annoying with pushing my choices onto others.

There is still a further reason that definitely convinced me to abandon MS Word when I wrote my dissertation: you…
