I built a smart blocker after destroying my dopamine baseline▲20
I'm a solo dev. A few years ago, I got addicted to Reddit. Spent months in that loop. Being a programmer, I thought I'd be clever. Redirected Reddit's domain to nowhere in my DNS file. Worked great until I'd just... open the file and undo it 20 minutes later. So I made it irreversible. Locked the DNS file so it can't be edited unless I boot my Mac in safe mode.

Hey there, HN! My name is Rishit, and this is my first post here on HN. Let me start off by asking you a question. How many tabs do you have open in Chrome right now? If you said less than five or ten: Congratulations, you’re not suffering from the dreaded 'Too Many Tabs Syndrome' (TMTS). Well, most probably! We all grow and start from zero. What?! Say that again. Did I hear you correctly? 25? 50? 100? Maybe even more? Or you’re just too lazy like me and said ‘too many’ since you can’t count them on your fingers? Woah! Now we’re talking! Yeah, yeah, I know, we’re in HN land after all, so I…
