AI Agents with Memory Part 3: Semantic Memory – Building a Long-Term Knowledge Layer with Qdrant and Python
Episodic memory records what happened. Semantic memory stores what the agent has learned. This part builds a production semantic memory layer using Qdrant and Python, with fact extraction, importance-weighted upserts, and similarity retrieval that lets agents build genuine knowledge about users and domains over time.
The April 2026 Enterprise IT Report: IBM Bets on Arm, Wireless Networks Face a Security Crisis, and Hybrid Cloud Locks In as Standard
Enterprise IT in April 2026 is shaped by IBM and Arm building dual-architecture mainframes, a wireless security crisis driven by a talent exodus, and hybrid cloud cementing itself as the standard operational architecture. This roundup covers what changed, what the data says, and what IT leaders should act on now.
AI Agents with Memory Part 2: Episodic Memory – Storing and Retrieving Conversation History at Scale with PostgreSQL, pgvector, and Node.js
Episodic memory is what lets an agent remember what happened in past sessions. This part builds a complete production episodic memory system using PostgreSQL with pgvector, implementing hybrid time-based and semantic retrieval in Node.js so your agent never starts from zero again.
AI Agents with Memory: Why Single-Session Agents Fail in Enterprise and the Three Memory Types That Fix It
Most agent guides cover single-session work. Enterprise agents need persistent memory across sessions. This first part explains why stateless agents break down at enterprise scale, introduces the three memory types that solve it, and maps out the architecture this series will build.
The April 2026 Developer Stack: TypeScript Tops GitHub, Rust Rewrites the Toolchain, and Copilot Goes Agentic
April 2026 marks a turning point for software development: TypeScript claims the top spot on GitHub, Rust powers the JavaScript toolchain, Python gets free threading, and GitHub Copilot transitions from autocomplete tool to autonomous coding agent.
Production Monitoring for LLM Caching: Cache Hit Rate Dashboards, TTFT Measurement, and ROI Calculation
Shipping caching without monitoring is flying blind. This final part covers how to build cache hit rate dashboards, measure time-to-first-token improvements, calculate real cost savings with accuracy, detect cache regression before users notice, and build the business case for continued caching investment.
Agentic AI in 2026: How Autonomous Systems Are Reshaping Enterprise Technology
Gartner projects 40 percent of enterprise applications will embed AI agents by end of 2026. This post covers the agentic AI shift, MCP hitting 97 million installs, the April 2026 frontier model landscape, OS-level AI integrations, and the governance gap enterprises must close.
The April 2026 Tech Power Shift: OpenAI at $852B, Microsoft’s Global AI Bets, and Consumer AI Hardware Takes Center Stage
The first week of April 2026 reshaped the tech industry across four fronts: OpenAI closed a record $122 billion funding round at an $852 billion valuation, Microsoft committed $10 billion to Japan’s AI infrastructure, Meta launched prescription-ready Ray-Ban smart glasses powered by Llama 4, and Cisco unveiled a Zero Trust security framework for autonomous AI agents at RSA 2026.
Multi-Provider AI Gateway in Node.js: Unified Caching, Routing, and Fallback for Claude Sonnet 4.6, GPT-5.4, and Gemini 3.1 Pro
A unified AI gateway abstracts over provider-specific caching implementations, routing logic, and fallback handling. This part builds a production-ready Node.js gateway that handles Claude Sonnet 4.6, GPT-5.4, and Gemini 3.1 Pro transparently, with cross-provider cost tracking and cache hit monitoring.
