Article 1ANN Index Types Explained: When to Choose Flat, HNSW, IVF, or IVF-PQTLDR: If your dataset is small and correctness is critical, use Flat. If you need high recall with low latency and enough RAM, use HNSW. If your corpus is huge and memory is your bottleneck, use IVF-P14 min
Article 2ACID Transactions in Distributed Databases: DynamoDB, Cosmos DB, and Spanner ComparedTLDR: ACID transactions in distributed databases are not equal. DynamoDB provides multi-item atomicity scoped to 25 items using two-phase commit with a coordinator item, but only within a single regio39 minArticle 3AI Architecture Patterns: Routers, Planner-Worker Loops, Memory Layers, and Evaluation GuardrailsTLDR: A single agent loop is enough for a demo, but production AI systems need explicit layers for routing, execution, memory, and evaluation. Those layers determine safety, latency, cost, and traceab14 min
Article 4Multistep AI Agents: The Power of PlanningTLDR: A simple ReAct agent reacts one tool call at a time. A multistep agent plans a complete task decomposition upfront, then executes each step sequentially — handling complex goals that require 5-115 minArticle 5Algorithms for AI: Trie, Graph Sorting, and K-Way Merge for LLM SystemsTLDR: Generative AI relies heavily on classic computer science algorithms under the hood. In this guide, we explore how to implement Trie prefix filtering for constrained model decoding, Topological S13 minArticle 6Clock Skew and Causality Violations: Why Distributed Clocks LieTLDR: Physical clocks on distributed machines cannot be perfectly synchronized. NTP keeps them within tens to hundreds of milliseconds in normal conditions — but under load, across datacenters, or aft19 minPage 1 of 3
