https://www.jameryw.dev/notes.html Working notes on Agent engineering, kernels, memory, and build-in-public. zh-cn Wed, 21 Oct 2026 00:00:00 GMT https://www.jameryw.dev/note.html?slug=why-agents-matter https://www.jameryw.dev/note.html?slug=why-agents-matter Sun, 31 May 2026 00:00:00 GMT I care more about continuous execution, memory, and tool collaboration than about polished single-turn answers. Agents https://www.jameryw.dev/note.html?slug=prototype-first https://www.jameryw.dev/note.html?slug=prototype-first Sun, 31 May 2026 00:00:00 GMT Get it running first, then let the real problems surface. Many judgments only hold once the interface and the scripts work together. Build https://www.jameryw.dev/note.html?slug=interface-as-signal https://www.jameryw.dev/note.html?slug=interface-as-signal Sun, 31 May 2026 00:00:00 GMT Interface choices reveal technical understanding and product judgment, so the site itself should be part of the work. Interface https://www.jameryw.dev/note.html?slug=prompt-engineering-evolution https://www.jameryw.dev/note.html?slug=prompt-engineering-evolution Sun, 31 May 2026 00:00:00 GMT Prompt engineering is shifting from handcrafted tricks to structured interfaces — from writing prompts to designing tools and orchestrating flows. Prompt https://www.jameryw.dev/note.html?slug=build-in-public https://www.jameryw.dev/note.html?slug=build-in-public Sun, 31 May 2026 00:00:00 GMT Building in public isn't performance — it turns the iteration process itself into signal, making ability, judgment, and execution directly verifiable. Philosophy https://www.jameryw.dev/note.html?slug=productivity-and-relations https://www.jameryw.dev/note.html?slug=productivity-and-relations Tue, 09 Jun 2026 00:00:00 GMT Productive forces determine production relations: organizations that match new productive forces with old forms will ultimately be replaced by a more radically efficient form. Org https://www.jameryw.dev/note.html?slug=evolve-in-loop https://www.jameryw.dev/note.html?slug=evolve-in-loop Wed, 10 Jun 2026 00:00:00 GMT Evolution isn't a one-time leap but the accumulation of countless closed feedback loops. Each loop is a calibration: act, feedback, adjust, act again. Loop https://www.jameryw.dev/note.html?slug=quantity-to-quality https://www.jameryw.dev/note.html?slug=quantity-to-quality Fri, 26 Jun 2026 00:00:00 GMT Sustained high-quality data produces high-quality strategies, and high-quality strategies spawn new alpha. It's a self-reinforcing flywheel, not linear accumulation. Alpha https://www.jameryw.dev/note.html?slug=knowledge-depreciates-experience-appreciates https://www.jameryw.dev/note.html?slug=knowledge-depreciates-experience-appreciates Thu, 02 Jul 2026 00:00:00 GMT AI rapidly depreciates retrievable knowledge while appreciating engineering experience earned from real failures. Designing distributed architectures that survive hundred-million-scale concurrency takes more than textbook basics. Judgment https://www.jameryw.dev/note.html?slug=skills-devoured-tools-fortified https://www.jameryw.dev/note.html?slug=skills-devoured-tools-fortified Mon, 13 Jul 2026 00:00:00 GMT The stronger models get, the more pure-software skills get devoured like free APIs. Truly hard to replicate are tools that touch the physical world — sensors, actuators, private protocols, real-environment feedback loops. Moat https://www.jameryw.dev/note.html?slug=pure-software-devalued-physical-premium https://www.jameryw.dev/note.html?slug=pure-software-devalued-physical-premium Tue, 22 Sep 2026 00:00:00 GMT Large models keep internalizing pure-software capability into free infrastructure, while software-hardware integration tied to the physical world appreciates on the back of real-world data loops. Value https://www.jameryw.dev/note.html?slug=ai-k-shaped-divergence https://www.jameryw.dev/note.html?slug=ai-k-shaped-divergence Wed, 21 Oct 2026 00:00:00 GMT AI splits the world into a K: apps go liberal-arts — taste and character decide who wins; tech goes hardcore — hardware bound to the physical world, perception–action–feedback in real environments, and self-evolution. Divergence
