APK Size Optimization Techniques for Game Center Application

Ke Jie explains why reducing the Game Center APK—by eliminating alpha‑PNG images, unused code and resources, limiting language and density assets, disabling v1 signing, compressing images, loading native libraries on demand, shipping only 64‑bit binaries, enabling code/resource shrinking and R‑file inlining—cut size by about 31% (≈20 MB), boosting download conversion and launch performance.

Technical Debt: Definition, Classification, and Management Practices

Technical debt, introduced by Ward Cunningham, describes the hidden cost of rushed or sub‑optimal code that degrades efficiency, quality, and developer experience; it arises from intentional or unintentional shortcuts across four dimensions, and can be managed through systematic identification, analysis, resolution, review, and dedicated ownership, yielding more stable, higher‑quality software.

Redis Cluster Slot Migration Optimization Based on Master-Slave Replication Mechanism

Vivo’s storage team redesigned Redis cluster slot migration by disguising the target as a slave and using master‑slave replication with progressive loading, which eliminates ask‑move round trips, reduces latency spikes, consolidates topology updates, and ensures stable access and high availability during horizontal scaling.
