SpeedCrunch - The best and only calculator you'll need, completely stripped down of unnecessary UI clutter. - Source: dev.to / over 5 years ago
I personally really like using speedcrunch[1] as a desktop calculator, and it’s cross platform. It’s not doing pretty print though. Otherwise it’s wolfram alpha[2], but that needs internet. I never type calculations in any search engines, but that’s way too slow compared to speedcrunch. Maybe I feel similarly to chalk using a web view compared to how electron apps are seen by some. Displaying inaccuracies is neat!... - Source: Hacker News / over 5 years ago

I like the Databases section of CodeSignal Arcade. Problems increase in difficulty, plus I've found it's the platform a lot of companies use for SQL assessment so you'll get a good sense of the type of questions to expect. Source: over 4 years ago
Codesignal has a good set of SQL questions. Not sure they "support" Postgres, but there's 84 free levels under the Arcade section. https://app.codesignal.com/arcade. Source: almost 5 years ago
