> The business owners I know who have been successful historically are seeing a 2x improvement and are completely unsatisfied. It's shattered their perspective on what is possible, and they're rebuilding their understanding of business from first principles with the new information.

Why are they not satisfied with the 2x improvement? Could you give an example of the "rebuilding" that you mean?

Ask HN: Why do we need things like 8sleep? Is sleeping with blankets unnatural?

Virtually all JavaScript engines are written in compiled languages. (Most runtimes for that matter nut just JS)

No, not at all actually. But I had a lot of applications where at somepoint we needed to add storage of currency in the database. It became relevant for billing or other features. This without the app itself being financial in nature.

Personally the lack of a decimal type make SQLite a no-go for me. Its too much of a hassle to do financial operations completely on the application side.

Why is EF regarded as such a good ORM? I've encountered countless bugs in different repos related to its stateful nature after many years in .NET. Personally I found it completely illogical for my ORM to maintain state. I just want it to hold my schema and build queries.

Yes, european roads are not as wide, since they make place for proper sidewalks and bike lanes. Another advantage is that narrower roads make drivers drive more carefully and slowly, reducing accidents even further.

Not the same, since if you buy Bitcoin, you don't have partial ownership of the machines used to mine and also these machines being used for a singular purpose which you cannot change.

I think in the end step by step functional programming will be widely adopted. Concepts that have a strong theory behind them tend to last longer. Similar to how relational databases and SQL are still the gold standard today.

> - Signal: how can you believe it is not controlled once it becomes the mandatory app in the US Gov.

Isn't this a good sign? When the US Gov has enough trust to use it internally and officials are already using it for their communications, would this not mean that the service is truly encrypted.

They could have some sort of switch for it, but the frontend is open-source and that's where the encryption happens.
