• The complexity of package and dependency management in software development makes it difficult to express boundaries between dependencies and automate the process.
• Solutions proposed include providing installation prerequisites, using a single package manager, and using general-purpose package managers such as Spack, Conda, Nix, and Guix.
• Package URLs can be used to name packages and a universal versioning system can be used to deal with version ranges.
• The universal versioning system can accommodate different versioning schemes and express version ranges in a universal way.

• CRDs are used to extend Kubernetes and as projects grow, the definitions of the resource start to evolve and may completely change, requiring versioning of CRDs
• Versioning of CRDs can be tough as end users need to be provided with seamless upgrades, zero downtime and backwards compatibility
• There are two views of CRD versioning: server version and stored version
• There are two conversion strategies: last mile change and full conversion
• The conversion package simplifies conversion functions between API versions
• The storage version migrator component bumps up existing objects to the new desired storage version
• Lossless conversion is followed where users can roll back to the older version
• Annotations of the field of the CR are used to store functions which lose data between versions

• Structured and easily queryable location for data cataloging is important
• Quality of data should be known to avoid wasting time on processing and feature processing
• Catch regressions early by putting checks upstream in the build process
• Lock device version for on-device logging
• Record metadata for debugging purposes
• Involve subject matter experts for debugging machine learning models
