Md Nasim Sheikhnasimstg.devIndependent Systems Press
Short, data-driven technical books on how systems actually work. Every claim is measured with an open-source benchmark harness or cited to a primary source. Nothing here is hand-waved.
The Independent Systems Bundle
All four measured systems books, together - write paths, vector search, compression, and service routing, each with its reproducible benchmark - plus both free pocket references, bundled in. Save $23 (about 32%) vs buying the paid titles separately.
LSM-tree vs B-tree storage engines, measured
HNSW vs IVF vector-search indexes, measured on the same vectors
gzip vs LZ4 vs Zstd vs XZ vs Brotli - ratio vs speed, measured
iptables vs eBPF service routing in Kubernetes
A one-page regex pocket reference. Every pattern tested.
grep / sed / awk / sort by example, with real captured output
