Re: Real-time gating of user actions
Sam Gödel-Conway

"Today, if you don’t want to build your own ledger, you do have a few options. For example, there are hosted services like Modern Treasury and ledger-specific databases like TigerBeetle. Both of these are impressive and probably a good fit for many. But by using a ledger outside of the main application database, you lose transactionality and atomicity. Namely, you have to worry about orchestrating two systems that can fail independently. What happens if you write your main data, but the ledger update fails? Or the ledger operation succeeds but your app hits an error and fails to write the surrounding data. Integrating with these often requires two-phase commits and other strategies to ensure they stay in sync. And when they fall out of sync, it can be very hard to debug." https://www.pgrs.net/2025/03/24/pgledger-ledger-implementation-in-postgresql

How to approach Purple Data in the Modern World
Paul Thaler-Williams

Bob Nystrom wrote a famous post entitled "What Color is Your Function?" - https://journal.stuffwithstuff.com/2015/02/01/what-color-is-your-function/ It discussed the tension in software between how sync and async functions behave. A new category of data is emerging that I call "purple". This is produced by LLMs. The property is transferable. Any data or function that uses LLM-generated data is purple, and any data or function based on the same is also purple. Keeping track of AI provenance is crucial going forward, as is providing checks on the data produced by purple functions. So, I present a new approach: https://llmsmr.io It summarises text using an LLM, but also provides tools to quickly check the result by extracting direct quotes and presenting them to the user. The summary is purple, but the quotes can be verified simply to ensure that they do indeed appear in the original text. I believe this approach should be applied to all purple data going forward.
