"Communications of the ACM" (https://cacm.acm.org/) is a great source for a variety of topics. It recently went digital-only and is included in an ACM membership.
> ACM will become fully Open Access by the end of 2025, but we have already begun that process in phases and large parts of the ACM Digital Library are already Open Access today, including the first 50 years of ACM's archive - all articles published between 1951 and 2000 have been placed in front of the ACM Digital Library subscription paywall.
