Why OFFSET Pagination Slows You Down: Switch to Keyset and Cut Latency from Seconds to Milliseconds

The article recounts how an API that originally used OFFSET pagination suffered 2‑3 seconds response time, and after rewriting the query to Keyset (Seek) pagination—adding a secondary sort key for stability and exploring cursor pagination, index‑only OFFSET, and materialized views—the same endpoint now responds in under 200 ms, with detailed benchmark comparisons.

Why Docker Dominates Cloud Computing by Reusing Decades‑Old Technologies

Docker’s success stems from stitching together decades‑old OS primitives—chroot, Linux namespaces, layered tar filesystems, SLIRP, and QEMU—so developers can keep their existing workflows unchanged, allowing containers to become the de‑facto operating system of the cloud era.
