The history of this "There are only two hard things in Computer Science: cache invalidation and naming things" quote attributed to Phil Karlton is slightly interesting. 1) According to Tom Bajzek on Phil Karlton's son's

A lot of tech improvements are s-curves or waves of s-curves, not exponentials. For a given problem domain you will still have s-curves, but for overall intelligence/progress it might be exponential in some overall sense.

re: debugging I dont disagree but here's another spin on what you observed. Kernighan's law says you have to be twice as intelligent/skilled when debugging the code as you were when writing it. A LLM centric corollary would b

Ah yeah, makes sense. The docs are misleading. The tricky thing with DateTime SCD2s vs Date-only SCD2s is that DateTime SCD2s work for identifying what was true for a given click/transaction/ingest time, but doesn't work for

Great point. That said, the remaining problem is that regular API calls dont scale/perform well for integrations between systems involving lots of data syncing. A few records? Fine. Many? Not so much. I would love to be wrong on this.

I've only been involved with such Salesforce integrations at one company, but based on that, I can give you my take. I'd be interested to hear others'. One, the salesforce data changes all occur through APIs (ok) which variou

Minor nit. Some SQL databases allow you to return multiple tables. IIRC, SQL Server stored procedures can do that. Agreed its not a language feature of SQL.
