    The blockchain is essentially a ledger that tracks transactions (including the creation of currency). One thing that is not always clear is how important it is for a blockchain to be decentralized. When I say “decentralized,” I mean that many different people are operating a server that performs transactions on a larger network. These people are rewarded in currency for their efforts, and are sometimes referred to as “miners,” though this term is changing somewhat.

    There are thousands of these servers in a network that are operating on and tracking the ledger for blockchains like Bitcoin or Ethereum. Any updates to the ledger are verified by all of these nodes. As long as 51% of nodes can verify a transaction, it will be added to the ledger. This means that as long as someone doesn’t own 51% of the network, they can’t just inject whatever transactions they want (i.e., fraudulent activity). In practice, this makes these networks very resilient to fraud.

    I think this paves the way for a lot of the practical examples you’re looking for. For example, there’s no way for the network to decide to just give tons of money to a single entity for some “economic policy” like Too Big to Fail (i.e., corporate bailouts). This means you don’t have to wake up one morning worrying about whether or not your currency will rapidly inflate because of things like corruption. Another example is the true ownership of digital assets. NFTs have (rightly) gotten a lot of flack for being overpriced JPEGs, but there are real use cases here. A random middleman can’t just decide to price gouge because they own all the tickets first (Ticketmaster). Instead, artists can mint tickets on the blockchain (very important: this ensures authenticity) and then fans can buy them on the blockchain - no middle man required. You still show a QR code at the door for verification like you would now.



  • The guy who leads this group is extremely vocal (almost weirdly so) about white privilege and systemic racism. He is also white. It’s true that many AI models have white-bias. The reasons for this are multi-faceted. Our datasets are grossly imbalanced against racial minorities. I also think I understand that for some darker-skinned races, it is more difficult for the model to extract relevant features from the shitty Flickr photos they scrape for these models.

    That said, injecting words into the users prompt to force the model to generate minorities more often is an extremely naive approach. Kind of like if Google added “reddit” to all searches just because it worked for some specific test cases, but ignoring that you now no longer get any site except reddit. Probably the solution here looks like paying a lot of money for high quality datasets as well as investing in user education and more AI explainability of these tools.

    I left out a crockpot of mostly eaten mac and cheese on the counter. I was on the couch half-asleep when I heard my keys (which were next to this crockpot) jingle. I didn’t say anything, I just turned my head and saw my cat running for cover as if it had just tripped the alarms during a heist gone wrong. How do I interpret this in any way other than my cat knowing what it was doing was naughty?



  • There’s a restaurant in my hometown of Lexington, KY called "“Frank and Dino’s.” It’s owned by Carlo Baccarezza who has ties John Gotti, who was Italian mafia. He’s a horrible person and has been sued by former employees of the restaurant for discrimination.

    He opened this place just before the pandemic. It’s supposed to be a fine-ish dining establishment with authentic Italian. The prices are high, but the food is terrible. It might be passable for someone who doesn’t know authentic Italian. In any case, the restaurant sits empty most of the day, and it doesn’t make sense to me why you would open a place like this and just allow it to have a terrible reputation that’s mostly empty day in and day out.
