Spotty memory but the two posts that made me check HN daily were: - How do you store data to last more than 50 years (diamonds and titanium were mentioned) - The announcement that bitcoin reached 1 USD, a great party story (TL;DR I tried buying 100, had issues w/ payment, got pissed, bought 200 instead, lost wallet a few months later, would have sold it super early tho)
