This is especially true when you're working with popular frameworks that been around for awhile, e.g. rails or even django at this point.
Most accepted answers I come across for questions I have with rails are a mix of:
* Use this niche gem I created, which btw has no license and hasn't been updated in 5 years
* Use this approach which depends on rails internals from 4+ major versions ago
* Use this rails helper which has been long-deprecated and removed in modern rails
At this point I just use Phind [1] -- it's quite good at niche rails questions and I can specify that I want "Rails 7.0 or Edge" answers only so it won't give me an answer from 2011 or 2013.
