What is HÆX?
I don't know. An internet alias used by me?
The domain name was available, and it's a cool combination of "hacks" and the norwegian Æ.
It's pronounced like "hacks", as in "That dude hacks everything".
Also HEX (magic and spell casting) is pretty cool because I love games and mysteries.
All together, HÆX. Seems to describe me 😅
Internationally (where the æ is not common) the domain name can be used as xn--hx-1ia.com (Internationalized domain name)
