Welcome to Software Development on Codidact!

Will you help us build our independent community of developers helping developers? We're small and trying to grow. We welcome questions about all aspects of software development, from design to code to QA and more. Got questions? Got answers? Got code you'd like someone to review? Please join us.

Search

Advanced Search Options

To further refine your search, you can use additional qualifiers such as score:>0.5. For example, the search score:>=0.5 created:<1y grammar would return only posts mentioning "grammar" that have a score >= 0.5 and were created less than a year ago.

Further help with searching is available in the help center.

Quick hints: tag:tagname, user:xxx, "exact phrase", post_type:xxx, created:<N{d,w,mo,y}, score:>=0.5
