I used to browse certain subreddits for negativity bait. Eventually I decided that I didn’t want to immerse myself in a negative mindset so often.
The trick for me was to recognize those moments when I was on auto-pilot and navigating to those spaces because I was bored and it was a reflex. I would remind myself that I know it’s bad for me, and then force myself to do literally anything else. Go to some other website. Vacuum the floor. Put on some music and go for a walk. Eventually I lost that reflexive instinct, and now I have no desire to go back to those places.
I’m not going to pretend that what worked for me will work for anyone else, nor will I say that I’m now a better person for avoiding those spaces. I’ve probably replaced that habit with an equally pointless one, it’s just nice to not always view things from the context of tearing others down.
There’s a JTAG port in the base of the cortex for pushing firmware updates. Problem is, we lost the signing keys back in the neolithic. Thag got crushed by a mammoth before we had a chance to invent written language and write documentation.
