The hacker culture is still there but hacker social media (unless carefully curated) is flooded with optimized content to the point where the cool stuff is hard to find and you only see the grifter techs.
Having lots of fun tinkering with Proxmox, Wled, Shelly devices to manipulate electric rollers, and more. Couldn’t quite get Valetudo running on my robot vacuum (my model isn’t the easiest to hack) but the concept is so cool. Triggering automations With dirt cheap NFC tags or a cheap wireless numpad is so satisfying.
Building an *arr stack is another area where there’s tons of amazing creativity online and the hacker spirit still lives on.
