• Explicit lazy imports for Python: another attempt at a long-desired language feature.
• A brief history of RubyGems.org: a background briefing on the Ruby package repository.
• The RubyGems.org takeover: what has been going on in the Ruby community, and what happens next?
• Large language models for patch review: creating code is not the only way that large language models might prove useful for kernel development.
