Ask HN: What engineering trivia earned you the most cred
Is there a specific piece of engineering knowledge that powered you to substantially contribute?
A software engineering example: knowing that Postgres FK doesn't implicitly create an index. Three different projects I joined weren't aware of this and we managed to improve the performance with a negligible amount of effort.
Keen to hear your wins (and make them mine ^^
- catlover76 1y ago> knowing that Postgres FK doesn't implicitly create an index. Damn really lol What does it do then, just block "breaking" deletes?
- porkbrain 1y agoYou can cascade the deletes in db layer rather than in app layer

- austin-cheney 1y agoDeeper internal knowledge of WebSockets and HTTP got me my current job.
- deanmoriarty 1y agoEvery time I start doing some network packet-based troubleshooting, for example firing up tcpdump to debug a tcp window size improperly tuned that caused a performance degradation over a high latency link (this is a random example I did last week), coworkers look at me like I pulled off some sort of wizardry. I feel it’s knowledge that most SWEs working on distributed systems should have acquired early and routinely use, but clearly that’s not the case.
