Apparently it's supposed to be some kind of advent calendar type thing, 25 posts in 25 days. Which explains the christmas tld.
Exactly that. Bekk, a Norwegian agency, has built a few advent calendars themed around various aspects of programming and product development. There’s FP, JS, Kotlin, UX, etc
I'll admit the only reason I've noticed the domain is my corporate IT seems to have all sites on weird TLDs blocked by default :/
