Can I run Linux on it ? I almost feel like being able to completely rebuilt computer technology from raw materials should be encased in a book somewhere. Hypothetically if we dropped you and 100 other engineers in the woods with metal working equipment could you get something resembling a computer working in 5 years ? Or in this post-apocalyptic landscape would it be more practical to dig in landfills for old GameCub…

Wikidata, SPARQL, and RDF in general. And I guess semi-relatedly things like Prolog? I recently decided to fiddle with Wikidata, and it is fascinating to be able to query for any part of a statement, not just the value! In SPARQL you write statements in the form But the cool part is that any of those three parts can be extracted, so you can ask things like "what are the cities in ", or "what country harbors the city…

- oracles for blockchain - Blockchains are secure systems because they're isolated systems. But smart contracts aren't very exciting without data from the real world. Oracles are the bridges to supply data from the real world to the blockchain world. However, a system is only as strong as its weakest link. You'd want the same security guarantees as what blockchain can provide. So the blockchain needs to "trust" oracl…

I recently came across Polymarket[1] and am really excited about what crypto has in store for prediction markets and insurance. I've dabbled in prediction markets over the years. I think they have a lot of promise but execution is always an issue. Using ETH to create a two-sided marketplace feels much better than having prediction markets decide what one can bet on. More broadly, decentralizing insurance in this way…

Fees are borderline insane if you are a small volume trader. If you’re in the US there is a regulated prediction market set to launch soon.
