AI for Science and embodied AI could drive the next wave, but neither will scale before the infrastructure bill comes due.https://blog.vonng.com/en/ai/bad-apple/Thu, 29 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/bad-apple/The 512 GB RAM upgrade alone costs more than a second Mac Studio, while a touchscreen MacBook, a 60 Hz iPad mini, and cracking foldable screens round out a disappointing week. Apple is still local AI’s strongest hardware ally, but how much longer can its memory and storage markups hold?https://blog.vonng.com/en/ai/ikigai/Wed, 28 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/ikigai/AI has driven the cost of prototyping software down to nearly zero, leaving conviction, verification, and long-term maintenance as the real bottlenecks. The first rule of choosing what to build is dogfooding: solving your own concrete problems is what carries you through the final 20%, builds trust, and compounds into an unfair advantage.https://blog.vonng.com/en/db/minio-silo-1year/Tue, 27 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/minio-silo-1year/One year after open-source MinIO was archived, how Silo uses AI agents, production user feedback, and strict scope boundaries to patch vulnerabilities, restore the web console, and maintain drop-in compatibility.https://blog.vonng.com/en/misc/kimi-marketing/Mon, 26 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/misc/kimi-marketing/Kimi’s overseas marketing controversy brings an old problem to the surface: paying for ads while pretending they are organic word of mouth. How undisclosed sponsorships poison technical information sources, and why I turn down paid promotions to keep the freedom to speak plainly.https://blog.vonng.com/en/ai/llm-personaility/Sun, 25 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/llm-personaility/ChatGPT is the cautious chief engineer, Claude the strategist, Gemini the staff writer, and GLM the unbothered grunt. Notes from heavy daily use on how each model behaves, what it over-optimizes for, and how six frontier models review one another.https://blog.vonng.com/en/misc/ev-experience/Sat, 24 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/misc/ev-experience/After 12 years of driving gas cars, I rented a range-extended EV for a road trip to Huangshan. What won me over wasn’t fuel savings, but the attention freed up by assisted driving—though beyond the cabin comfort and easy charging, data privacy and vehicle ownership still bear thinking about.https://blog.vonng.com/en/db/1024-festival/Sat, 24 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/1024-festival/Human computers became the first programmers; today’s programmers stand at the same crossroads. As AI takes over coding, an engineer’s value shifts to design, taste, delivery, accountability, and orchestrating fleets of agents.https://blog.vonng.com/en/cloud/net-attack/Thu, 22 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/cloud/net-attack/From PHP and GitLab to AI toolchains and certificate authorities, half the internet was breached in a single week. As AI accelerates vulnerability discovery and exploitation, active maintenance, clean upgrade paths, and timely security patches have become non-negotiable for infrastructure.https://blog.vonng.com/en/cloud/blackwall/Wed, 21 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/cloud/blackwall/TiDB Cloud breached, Zeabur shutting down, PostgreSQL 19 delayed: as AI accelerates vulnerability discovery and exploitation, how does the patch deployment gap change the security calculus for cloud services? Local-first systems and physical isolation may be our last Blackwall.https://blog.vonng.com/en/trip/huangshan/Mon, 19 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/trip/huangshan/A family road trip from Shanghai to southern Anhui—rice paddies at Tachuan Academy, hairy tofu in Hongcun, and shipping the Silo October security release and Oink v1.3’s native photo gallery from the road.https://blog.vonng.com/en/ai/ai-bubble/Sat, 17 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/ai-bubble/AI capability, real-world adoption, and financial capital are moving on three out-of-sync curves. Demand is narrow and deep, while pricing, credit, and duration have fallen into a triple mismatch: how will the bubble unwind, and who captures the technological surplus left behind?https://blog.vonng.com/en/ai/funnel/Fri, 16 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/funnel/From 2 billion chatbot users to 5,000 frontier lab insiders: a five-tier Fermi estimate of AI adoption shows broad reach, but surprisingly shallow depth.https://blog.vonng.com/en/pg/revive-pg-cn-community/Mon, 12 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/pg/revive-pg-cn-community/A PostgreSQL community starts with its users. With a distribution, documentation, package mirrors, localized messages, and a Chinese-language portal now in place, the next step is connecting them into a community that serves users across the Chinese-speaking world.https://blog.vonng.com/en/pg/pg-zh-tw/Sat, 10 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/pg/pg-zh-tw/Both Simplified and Traditional Chinese message catalogs in PostgreSQL 19 now meet the release threshold across all 28 components. Chinese localization lowers reading overhead during production incidents, gives new users a better first impression, and fills basic documentation and community gaps that went neglected for years.https://blog.vonng.com/en/db/me-pro/Fri, 09 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/me-pro/Four spare hard drives and four NVMe SSDs fit neatly into a Beelink ME Pro. Why I chose it over the Minisforum N5, what assembly and Ubuntu setup involve, and what a NAS with enough CPU power to do more than store files can offer.https://blog.vonng.com/en/db/homelab-10g/Thu, 08 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/homelab-10g/Over China’s seven-day National Day holiday, I upgraded my home LAN to 10GbE, replaced two NAS boxes, and packed six machines into a rolling 12U rack. With AI helping on hardware selection, rack layout, and provisioning, one person can stand up a complete infrastructure stack.https://blog.vonng.com/en/ai/bye-claude/Sun, 04 Oct 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/bye-claude/Anthropic banned two of my Claude accounts during China’s October holiday. The hardest part to replace is two years of accumulated context, not the model itself—and the post-ban data export turned out to be a single-line JSON file containing only my user ID. A postmortem on what likely triggered the ban, my current workarounds, and how I’m reallocating my AI subscriptions.https://blog.vonng.com/en/ai/secretary-era/Tue, 29 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/secretary-era/From coding agents to always-on personal assistants, AI is starting to manage everyday life. A cloud computer, an identity, a wallet, and a group chat are becoming standard issue—but first decide whether you are hiring a digital extension of yourself, or an agent that needs permissions, audit logs, and hard limits.https://blog.vonng.com/en/ai/codex-promax/Sat, 26 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/codex-promax/ChatGPT Pro Max is priced at $500 a month, but the real question is the usage multiplier: 50× keeps the wholesale discount alive, while 25× or 20× signals shrinking subsidies—and turns the existing $200 Pro plan into a grandfathered relic.https://blog.vonng.com/en/pg/pg19b4-release/Fri, 25 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/pg/pg19b4-release/PostgreSQL 19 Beta 4 reverted five major features at once: SQL/PGQ property graph queries, online data checksums, temporal UPDATE and DELETE, partition merge and split, and DDL reconstruction functions. Features can wait another year; reliability cannot. Meanwhile, Simplified Chinese message translations landed upstream in Beta 4, and pgsql.cc completed a 28-year archive of Chinese PostgreSQL manuals.https://blog.vonng.com/en/ai/ai-native-org/Thu, 24 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/ai-native-org/What is happening is not transformation, but new species replacing old ones. Incentives and structure keep established companies from capturing AI’s gains. AI-native companies will grow from scratch, with new forms of organization.https://blog.vonng.com/en/ai/codex-video-cut/Wed, 23 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/codex-video-cut/I gave Codex three panel recordings and a casually dictated prompt. Forty-eight minutes later, it delivered a finished edit with subtitles, at an estimated amortized subscription cost of about 8 yuan. Coding agents are finding their way into everyday life.https://blog.vonng.com/en/ai/sor-harness/Tue, 22 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/sor-harness/As agents take over software interfaces and execution logic, where does the application layer go? Future software will consist of a lasting system of record and harnesses that are continually replaced and recombined. The operator can change. The books must stay straight. The rules must stay put.https://blog.vonng.com/en/misc/year-33/Mon, 21 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/misc/year-33/Turning 33, I look back on what may have been my most enjoyable year yet: one person, a team of agents, Pigsty, PostgreSQL’s Chinese ecosystem, Silo—and, somehow, work-life balance.https://blog.vonng.com/en/misc/game-theory-mad-pirate/Sun, 20 Sep 2026 00:00:00 +0000https://blog.vonng.com/en/misc/game-theory-mad-pirate/The pirate game, the people who flip the table, and the trap the decent ones are stuck in. A game theory of flipping the table: why the people who refuse to let things go are the load-bearing beam under every fair split.https://blog.vonng.com/en/pg/pg-nls/Sat, 19 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/pg/pg-nls/Never set your PostgreSQL locale to zh_CN: that old rule expires with PostgreSQL 19.

Then I found the same mechanism on my own machine.https://blog.vonng.com/en/db/silo-is-coming/Fri, 18 Sep 2026 00:00:00 +0800Ruohang Fenghttps://blog.vonng.com/en/db/silo-is-coming/On September 11, MinIO deleted the minio/minio and minio/mc repositories from Docker Hub outright, finishing its walk out the door. Over the past month or so I put two mutually adversarial AI agents to work on Silo, the MinIO community fork I maintain, and ran a full cleanup: four releases, 210 commits, 8 CVEs, plus compatibility hardening and a zero-cost migration path. One person with a pile of top-tier subscriptions can now genuinely carry the security maintenance of a mid-sized Go project.https://blog.vonng.com/en/ai/jev-shutup-model/Thu, 17 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/jev-shutup-model/Jev doesn’t talk. It looks at a state, hands you a probability for every option, returns in milliseconds, and charges nothing for output. What it fills in is the OLTP path AI never had—the model only estimates, the decision goes back to an if in your code, and the threshold falls out of the cost.https://blog.vonng.com/en/db/rustfs-ga/Thu, 17 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/rustfs-ga/Five days after MinIO vanished from Docker Hub, RustFS shipped 1.0 GA. I tested the binary-swap migration: unencrypted data survives a full stop-and-swap, and you can even roll back — but there is no rolling upgrade, encryption does not cross over, and three startup config items have to change. More than the feature list, the thing to watch is whether the open-source boundary gets walked back step by step.https://blog.vonng.com/en/misc/ice-cream-agenda/Wed, 16 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/misc/ice-cream-agenda/How does a verdict of “tastes awful” become a week’s public agenda? When someone with the power to set that agenda calls himself “just a consumer,” he conceals more than his power. He also conceals his obligation to face scrutiny.https://blog.vonng.com/en/db/drop-5tb-polardb/Tue, 15 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/drop-5tb-polardb/A PolarDB for PostgreSQL instance deployed in Docker on a single host lost 5 TB of data—no backups. Watching the recovery unfold, I would rather talk about the value of prevention, and how to make timely decisions once things go wrong.https://blog.vonng.com/en/ai/local-ai-movement/Fri, 11 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/local-ai-movement/Anthropic’s threat report, OpenAI’s soap opera, the closure of the $200 subscription tier, and rising GPU and memory prices—all of this week’s events tell the same story.https://blog.vonng.com/en/pg/pgsql-cc-online/Thu, 10 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/pg/pgsql-cc-online/pgsql.cc is live, with Chinese documentation for all 11 PostgreSQL major versions from 10 through 20, a redesigned mirror of the official website, and better full-text search.

The real bottleneck is turning tokens into useful output—and using automation to scale your time, attention, and ability to judge the results.https://blog.vonng.com/en/ai/astra-reset/Fri, 04 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/astra-reset/As Astra began rolling out, Tibo announced one banked reset per day for paid users still waiting for access. I’m stocking up for when Astra arrives.https://blog.vonng.com/en/ai/rag-is-dead/Wed, 02 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/rag-is-dead/The word RAG is still alive, but chunk-embed-top-k should no longer be the default answer. Look at the material first, then pick the architecture — and PostgreSQL is worth a great deal more than a place to park vectors.https://blog.vonng.com/en/ai/no-token-exit/Wed, 02 Sep 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/no-token-exit/A slide from a Nanjing University course said CS students without tokens should drop out immediately, and the Chinese internet split down the middle over it. What the fight is actually about: the junior jobs AI is erasing, an education system that cannot supply what students need, and why young people now have to build their own ladder.https://blog.vonng.com/en/ai/claude-opc-eval/Sat, 29 Aug 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/claude-opc-eval/I asked a neutral Claude with no memory of me to assess PGSTY and estimate what it might be worth.https://blog.vonng.com/en/ai/sdd/Sat, 29 Aug 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/ai/sdd/People often ask: how do I ensure quality when AI writes the code? My answer has four parts: documentation-driven development, adversarial review, brute-force testing, and complexity penalties.https://blog.vonng.com/en/db/catalog-bullshit/Fri, 28 Aug 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/catalog-bullshit/Snowflake blames the lakehouse’s governance gaps on multiple engines and turns the Catalog into a new billing layer. But the core of an Iceberg Catalog is just a metadata-pointer CAS; the real governance gap comes from separating the control plane from the data path.https://blog.vonng.com/en/db/aws-get-duckdb/Wed, 26 Aug 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/aws-get-duckdb/AWS bought the people who build the duck and left the duck itself to the foundation.https://blog.vonng.com/en/db/apple-m5-ultra/Tue, 25 Aug 2026 00:00:00 +0000Ruohang Fenghttps://blog.vonng.com/en/db/apple-m5-ultra/No teaser, no rumors—the website simply changed.
