Comparison of the TOP-3 production tools — Mem0, Letta (MemGPT), and Zep — across nine axes. Highlighting the gap: research outpaces tooling. https://triumphpc.github.io/blog/posts/sync-mutex-atomic/ Thu, 18 Jun 2026 00:00:00 +0000 https://triumphpc.github.io/blog/posts/sync-mutex-atomic/ Mutex and atomic are not two independent tools — they are one stack of abstractions. I dig through the stack from data race to starvation mode: why x++ is three ARM64 instructions, how CAS became a universal primitive (Herlihy 1991), why Mutex is built on top of atomic CAS, and how Russ Cox’s barging-vs-handoff debate (issue #13086) gave Go its 1ms starvation threshold. With public benchmarks, the bit layout of Mutex state, and a cheatsheet for when to reach for which. https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-6-memory-deep-dive/ Thu, 11 Jun 2026 00:00:00 +0000 https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-6-memory-deep-dive/ Deep dive into agent memory mechanics: five memory files, four context assembly strategies, TOOLS.md as a dual-source responsibility, and Dreaming — background consolidation from Anthropic (Auto Dream, Dreams API, KAIROS) and OpenAI (Dreaming V3, 82.8% factual recall). Engineering decisions behind a production platform. https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-4-multi-agent/ Mon, 08 Jun 2026 00:00:00 +0000 https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-4-multi-agent/ Five multi-agent orchestration architectures — Supervisor, Swarm, Debate, Assembly Line, Hierarchical — with Mermaid diagrams, code examples in Eino (Go), and an honest look at limitations. When one agent isn’t enough, and when you’re better off staying solo. https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-5-memory/ Mon, 08 Jun 2026 00:00:00 +0000 https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-5-memory/ Context window ≠ memory. I break down agent amnesia, the academic taxonomy (Du et al., 2026), five approaches to memory — from OpenClaw’s file-based brain to mem0’s managed layer — and how our team solves this in practice. https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-2-plan-execute/ Sun, 07 Jun 2026 00:00:00 +0000 https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-2-plan-execute/ Plan-and-Execute separates strategic planning from tactical execution. I break down the Planner+Executor+Reviser architecture, ReWOO and LLMCompiler variants with numbers from original papers, prompt injection defense via control-flow integrity, and a minimal working Go example with Eino. https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-3-reflexion/ Sun, 07 Jun 2026 00:00:00 +0000 https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-3-reflexion/ Reflexion is a pattern where an agent learns from its own mistakes through verbal reinforcement and episodic memory. I trace the evolution of self-critique from Constitutional AI to Reflexion, honestly show its limitations (doesn’t work without an external verifier), and implement a working example in Go using Eino compose.Graph with an Actor → Evaluator → Reflector → retry loop. https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-1-react/ Sat, 06 Jun 2026 00:00:00 +0000 https://triumphpc.github.io/blog/posts/ai-agent-design-patterns-1-react/ ReAct (Reasoning + Acting) — the foundational AI agent design pattern that interleaves reasoning and action in a single loop. I break down the architecture, numbers from Yao et al. 2022, framework landscape, and a minimal working Go example via Eino. https://triumphpc.github.io/blog/posts/getting-started/ Fri, 05 Jun 2026 00:00:00 +0000 https://triumphpc.github.io/blog/posts/getting-started/ How this blog was born — Hugo, PaperMod theme, Mermaid diagrams, KaTeX math, custom dark styling, and fully automated CI/CD via GitHub Actions.
