louis8799··on The Problem with LangChain
Calling LLM API is just 2 line of code. Building LLM App is just API Calling.

louis8799··on The working-from-home illusion fades
> Unfortunately for the believers, new research mostly runs counter to this, showing that offices, for all their flaws, remain essential. A good starting point is a working paper that received much attention when it was published in 2020 by Natalia Emanuel and Emma Harrington, then both doctoral students at Harvard University. They found an 8% increase in the number of calls handled per hour by employees of an online retailer that had shifted from offices to homes. Far less noticed was a revised version of their paper, published in May by the Federal Reserve Bank of New York. The boost to efficiency had instead become a 4% decline. The researchers had not made a mistake. Rather, they received more precise data, including detailed work schedules. Not only did employees answer fewer calls when remote, the quality of their interactions suffered. They put customers on hold for longer. More also phoned back, an indication of unresolved problems.

louis8799··on Json-Base – Database built as JSON files
Oh yeah, so basically had he pushed further, he would have realized to avoid corruption, he would need to implement "write ahead log (WAL)". An for the implementation of WAL and other performance concern, he would have realized that storing the JSON as string is not the way to go, he'd need to implement other binary data structure. Then he'd have realized that he had just invented another NoSQL DB.

Had he pushed further.....

Had he pushed further, he'd have raised funding for the newly invented NoSQL DB, and built a startup company on top of it.

louis8799··on PostgREST
I am not sure if it is a good idea to add PostgREST to your stack. As PostgREST can only interact with your DB, so you would probably be calling PostgREST from another REST. In this case, you would be better off using ORM.
