Jökull Sólberg
Co-founder and CTO of TripToJapan.com. This blog runs in two modes: helpful posts about TypeScript, agents, and the guts of shipping software, and much less helpful ones about Icelandic politics and the end of the Atlanticist order. The overlap in readership is approximately zero, and I've made peace with that. Reykjavík, Iceland.
