LLM 应用机会，不是更聪明的聊天框
Published:
LLM 最有价值的应用，可能不是回答问题，而是把一项专家工作变成可以执行、复核和审计的数字工作单元。
LLM 之后的世界，2030 年谁会被重新组织？
Published:
2030 年最值得观察的，不是有多少人被 AI 取代，而是哪些工作会被重新组织。

The Mom Test: From Reading It at SFO to Using It in Every Customer Interview
Published:
Some books leave behind a few ideas. The Mom Test gave me a method I continue to use: do not ask whether someone likes your idea. Ask what they have already done, how often the problem occurs, what it has cost them, and whether they will commit to a next step.
《The Mom Test》：我从 SFO 机场读完，到后来一直使用的用户访谈方法
Published:
有些书读完会留下一些观点，《The Mom Test》留给我的却是一套不断调用的方法：不要问别人喜不喜欢你的想法，要追问他过去真实做过什么、问题多久发生一次、已经付出了什么成本，以及接下来愿不愿意采取行动。
Steve Jobs Was Insulted in Public. His Answer Revealed Where Product Decisions Should Begin
Published:
When someone publicly told Steve Jobs that he did not understand technology, Jobs paused, conceded part of the criticism, and asked a more consequential question: what will the customer ultimately gain?
被当众羞辱后，Steve Jobs 没有反击，而是解释了产品决策的起点
Published:
一个人当众说 Steve Jobs 根本不懂技术，他停了十几秒，没有反击，只问了一件更重要的事，用户最终能得到什么？
Does “No Stupid Questions” Mean “Ask Anything” or “Do Not Ask Dumb Questions”?
Published:
A widely shared post describes a brainstorming meeting at a robotics startup in Boston. A slide said “No stupid questions.” A Chinese employee interpreted it as “Do not ask stupid questions,” while American colleagues explained it as “Ask freely; no question will be judged stupid.” A related post claims that “Say it again?” is neutral when someone is not heard, whereas “What did you say?” is hostile.
“No stupid questions”到底是“随便问”还是“别问蠢问题”？
Published:
一张流传截图讲了这样一件事：一家波士顿机器人创业公司开头脑风暴会，幻灯片写着 “No stupid questions.” 一位中国员工把它理解为“不要问蠢问题”，美国同事却说它的意思是“什么都可以问，没有问题会被当成蠢问题”。另一组讨论又声称：没听清时说 “Say it again?” 很中性，而 “What did you say?” 很不友好。
How I “Reasonably” Ended Up in the Wrong NEXUS Line at YVR
Published:
I ended up in the wrong NEXUS line at Vancouver International Airport. By the rules, the mistake was mine. By design, it was an almost predictable wrong turn.
我在 YVR“合理地”走错了 NEXUS
Published:
我走错了温哥华机场的 NEXUS 通道；规则上是我的错，设计上却是一条几乎可以预测的错误路径。
Another Side of Vancouver Airport: Age, Workspace, and the People I Saw
Published:
Beyond the wayfinding problem that led me into the wrong NEXUS line, my connection at Vancouver International Airport left me with several observations unrelated to signs. I noticed an older-looking mix of people, a departures area that offered almost nowhere to work, and a visible contrast between people in Vancouver and Texas. This post records those observations. The full account of the NEXUS incident is in How I “Reasonably” Ended Up in the Wrong NEXUS Line at YVR.
温哥华机场的另一面：年龄结构、办公空间与我看到的”人群”
Published:
除了那次走错 NEXUS 通道的导视问题，这次在温哥华机场（YVR）转机还让我观察到几件和路标无关、但同样值得记录的事情：明显偏大的现场年龄结构、几乎不为办公设计的候机空间，以及温哥华与得州人群景观的直观差异。这篇笔记单独记录这些观察；如果你想看我是怎么在 NEXUS 通道走错路的，可以读我在 YVR”合理地”走错了 NEXUS。
Air Canada Was a Mess: Three Seats, Fourteen Hours of Lavatory Odor, a Go-Around, and a Towing Delay
Published:
My verdict on Air Canada after flying from Singapore to Austin through Vancouver is simple: what a mess.
Air Canada 太拉了：一排三座、十四小时厕所味、复飞与拖机延误
Published:
这次从新加坡经温哥华飞回奥斯汀，我对 Air Canada 的评价很简单：太拉了。
Why Did a S$5.50 Purchase Appear as US$4.27?
Published:
A receipt in Singapore showed S$5.50, while a U.S. credit-card account displayed only US$4.27. Another purchase of about S$48 appeared as roughly US$38. A bank-card transit ride also failed to appear immediately as pending.
为什么 S$5.50 的消费在美国信用卡上只显示 US$4.27？
Published:
在新加坡消费时，一张收据写着 S$5.50，但美国信用卡账户只显示 US$4.27。另一笔约 S$48 的消费，则显示为约 US$38。与此同时，刷银行卡乘坐公共交通后，交易也没有立刻出现在 pending 中。
我在新加坡机场看到“亚洲最安全银行”：给10岁小朋友的银行安全课
Published:

AI Can Plan the Trip. It Still Cannot Get the Car to Move.
Published:
The last mile of an AI-generated travel plan may be one missing Retry button.
AI 能规划旅程，却还不能让车真正开起来
Published:
一份由 AI 制定的完美旅行计划，最后可能会死在一个不存在的“重试”按钮上。
AI Can Plan My International Trip, but It Still Cannot Clear the Payment Gate
Published:
The thing that almost stranded me on this international trip was not a typhoon, but several unrelated systems deciding at the same time that they did not trust me.
AI 能帮我规划国际旅行，但它还不能替我过支付这一关
Published:
这次国际旅行真正差点把我留在原地的，不是台风，而是几个互不认识的系统同时决定不相信我。
Is Contributing on GitHub Like Donating Sperm?
Published:
Here is an inappropriate analogy that nevertheless captures something real about open-source work:
在 GitHub 到处提 Issue 和 PR，为什么像“捐精”而不像“捐卵”
Published:
我提一个不太恰当、但确实抓住了开源协作某种结构的比喻：
Why alias rm=trash Cannot Stop an AI Agent from rm -rf
Published:
I asked Claude Code a narrow question: can I protect this machine from Codex accidentally deleting files forever, just by aliasing rm to trash? The honest answer turned out to be no, for a reason that is not obvious until you actually test it, and the fix ended up being a five-layer setup rather than a one-liner.
为什么 alias rm=trash 拦不住 AI agent 的 rm -rf
Published:
我问了 Claude Code 一个很具体的问题：能不能只靠把 rm alias 成 trash，来防止 Codex 意外把文件永久删掉。真实的答案是不能，原因不实测根本看不出来，最后落地的也不是一行配置，而是五层防护。
Benchmark 的价值、市场误判与提出问题的能力：一次和我滴好东北哥们儿（CMU）的原始对话
Published:
Benchmark 到底是在做研究，还是在“众筹一篇论文”？它是在创造公共价值，还是在占用公共资源？它能不能形成长期能力，还是只适合创业团队向投资人展示潜力？
Hard Benchmarks Should Not Become Coding Tricks
Published:
The most dangerous failure mode of an AI science benchmark is not that it is too hard, it is that it quietly becomes either a coding trick or a guessing game.
Do Not Secretly Record Customer Interviews
Published:
Secretly recording a customer interview can turn a useful research habit into a privacy problem in one click.

Why Your Brand-New WD Drive Is Read-Only on a Mac (It’s Not the Drive)
Published:
I plugged a Western Digital external drive full of data into a MacBook Air, tried to copy a file onto it, and nothing happened. No error dialog, no progress bar, just a drive that would let me read everything and write nothing. My first instinct was that something was broken, or that I needed to fix permissions. Both were wrong, and chasing the wrong explanation almost led me to permanently downgrade the security of the whole laptop.
为什么你崭新的 WD 移动硬盘在 Mac 上只能读不能写（问题不在硬盘）
Published:
我把一块装满数据的西部数据（WD）移动硬盘插到 MacBook Air 上，想往里拷一个文件，结果什么都没发生。没有报错弹窗，没有进度条，就是一块能读出所有东西、却一个字节都写不进去的硬盘。我的第一反应是它坏了，或者是我得去修一下权限。这两个判断都是错的，而且顺着错误的解释找下去，差点让我把整台笔记本的安全性永久降级。
Building a real ZIP bomb in Fortran, C++, and C
Published:
I’ve been playing with mixed-language builds (Fortran calling into C++ and C via iso_c_binding) and wanted a demo that was more interesting than “add two numbers across languages.” So I built fortran-zip-bomb: a small program that generates a genuine ZIP bomb — a small archive that expands into a much larger file on decompression.
A Materials-Science Model of Egg Fried Rice, Three Years Later
Published:
In October 2023 I asked ChatGPT an over-engineered question: how do you fry rice so that every grain of rice ends up bonded to egg, with no bare rice grains and no isolated clumps of egg sitting off on their own? I saved that conversation as an HTML file, dropped it in my Downloads folder, and did not look at it again for almost three years. Last week I finally turned it into an actual open-source repo, and going back through the original conversation to build it was more interesting than I expected.
蛋炒饭材料学模型，三年之后
Published:
2023 年 10 月，我问了 ChatGPT 一个过度工程化的问题：怎么炒蛋炒饭，才能让每一粒米都裹上蛋，既没有裸露的白米粒，也没有单独抱团、没沾到米的蛋碎？那次对话我存成了一个 HTML 文件，扔进 Downloads 文件夹，然后差不多三年没再打开过。上周我终于把它整理成了一个真正的开源仓库，回头重读那段 2023 年的对话、把它做成代码的过程，比我预想的有意思得多。

What It Actually Takes to Land a Patch in Git
Published:
In my first post on this I described sending a patch through GitGitGadget and watching it land on the mailing list as v1. That post ended with the patch waiting for review. It has since merged. Now that I have seen the full lifecycle, from typo to master, here is what actually mattered.
把一个补丁真正送进 Git 需要什么
Published:
在第一篇文章里，我写了怎么通过 GitGitGadget 把补丁发出去，它作为 v1 落在了邮件列表上。那篇文章结束在等待 review 的状态。现在它已经合并了。看完从一个拼写错误到进入 master 的完整过程，下面是我觉得真正重要的几点。

The Missing Scientists, Why 600 Years of Status Quo Is the Real Bottleneck in Science
Published:
A new paper looked at 739 science Nobel laureates from 1901 to 2023, and the headline number that came out is brutal, at the current rate of progress it would take roughly 600 years before a kid born into a poor country has the same shot at a Nobel as a kid born into a rich one.
消失的科学家，为什么 600 年才追得上才是科学真正的瓶颈
Published:
一篇新论文把 1901 到 2023 年所有 739 位科学类诺贝尔奖得主从童年扒到现在，得出了一个特别狠的数字，按目前的进步速度，一个出生在低收入国家的孩子要等大约 600 年，才能拿到和富裕国家孩子一样的诺奖机会。

My PhD Advisor Built a Land Surface Model That Forecasted Hurricane Harvey
Published:
When you join a lab, you do not just get a research direction. You inherit a 30-year codebase that is currently running inside the U.S. National Water Model and was on the critical path forecasting Hurricane Harvey. That is what working with Zong-Liang Yang at the Jackson School of Geosciences actually looks like.
Sean Xiang Has Been Building Bloombase for 14 Years, and the AI Era Finally Caught Up to It

Gemini Says My Ego Essay Is Still a Humblebrag
Published:
Earlier today I published a piece called “Four Ego Mistakes I Made as a 22-Year-Old Founder.” Then I ran it through Gemini 2.5 Pro as an independent reviewer. Gemini’s verdict was that the essay is itself an ego move. I think Gemini is mostly right.
Gemini 说我那篇 ego 文还是凡尔赛

22 岁 founder 的四个 ego 错误
Published:
Ego 不是以”嚣张”的形式出现的。它是以一组你偷偷在心里给自己记的假记分牌的形式出现的，你一旦把记分牌当成了真比赛，你就开始输了。
Eric Greene Built a Way to Watch Single Molecules of DNA Repair Themselves
Published:
Most of biology is averages. You measure a million cells, you get a mean. Eric Greene’s lab figured out how to actually watch one DNA molecule at a time, repair itself, in real time, and that changes what kind of questions biology can ask.
Trees Drink From Rock, and Daniella Rempe Proved It
Published:
If you ask most people where trees in California get their water in a drought, they will say “the soil.” It turns out a huge fraction of it comes from cracks in the bedrock underneath the soil, and Daniella Rempe is the person who put numbers on it.
I Spent a Week Building a Chronicle for Chen Ning Yang, and the Family Tree Was the Story
Published:
Most physics undergraduates know Chen Ning Yang as a Nobel laureate and the Y in Yang-Mills. Building him a chronicle made me see something the textbooks gloss over: the most consequential single fact about his life is who his father was, and what that father had set up for him before he was born.
Ashley Matheny Treats Trees as Pumps, and That Changes the Whole Model
Published:
Most land surface models treat a tree like a passive straw. Water comes in at the roots, water leaves at the leaves, end of story. Ashley Matheny’s research basically says no, a tree is an active hydraulic system with storage, capacitance, and a strategy, and if you do not model it that way you are going to be wrong about drought.
Zero to a Billion in Ten Years Sounds Normal, Until You Realize It Means Doubling Every Year
Published:
People love saying that ten years to a billion-dollar valuation is the normal pace for a unicorn, neither fast nor slow. But once you actually crunch the compound numbers, you realize what hides behind that word “normal” is a beast that doubles in value every single year.
十年从零到十亿美金，这种「正常」速度其实是每年翻一倍
Published:
很多人会说，十年估值十个亿美金，就是一只正常的独角兽，不慢也不快。但你真去算一下复利就会发现，这「正常」二字背后藏着一个每年估值翻一倍的怪兽。
Five Orders of Magnitude on Purpose, Why Text AI and Embodied AI Are Not Playing the Same Data Game
Published:
Call it a (10^5) gap if you like, once you put semantic entropy and effective training samples on the board, the difference between internet-scale text and embodied robotics data stops sounding like rhetorical inflation and starts sounding almost conservative. You just have to separate raw physics bits from semantics a learner can actually use.
五个数量级，「十万倍」可能还是保守的，第一性原理拆开看一眼文字 AI 与具身 AI 的数据鸿沟
Published:
「十万倍」这个说法乍听像聊天里随手甩出去的量级，但如果把它放回语义信息熵和有效训练样本这两把尺子下面，它非但不夸张，反而可能是保守的。关键是你得把「原始物理比特」和「带语义的、可被学习的数据」分开看。
Who Hoards Multimodal Data for Real, Meta, ByteDance, X, and the Visa Plot Twist
Published:
Ask which campus actually sits on the best multimodal feedstock for GPT-4V-class perception, Sora-class video, Gemini-scale bundles, and Meta Emu-style image stacks, and the short answer is almost vulgar in how cleanly it splits three big piles. Meta still pulls ahead by a chasm on stills, ByteDance owns the high-velocity short-video river that is really motion plus audio, and X ships the smallest absolute media volume yet the weirdest leverage on tight text-image coupling and live-event semantics.
「图片地主」对「视频钥匙」对「实时百科」，多模态家底Meta、ByteDance和X怎么分
Published:
这题问到刀尖上了。如果把「高质量多模态训练数据」收窄到对 GPT-4V、Sora、Gemini、Emu 这类模型真有喂饭价值的图文或视频，短答其实很锋利，Meta（Facebook / Instagram）静态图片数量的库存对其他两家几乎是断层第一，ByteDance（TikTok / 抖音）在短视频也就是动态图片流上占最大优势，X（Twitter）绝对量级最小，但图文的贴脸相关性和实时信息密度是独一份。
The Physics Professor Who Won’t Touch AI, and the Student Who Can’t Stop

Published:
A team has too many things, too many open questions, too many half-decisions floating across Slack threads and meeting notes, and the only way I have found to keep that chaos from turning into quiet decay is to force every piece of valuable knowledge into one place, the GitHub repo, and treat everywhere else as a temporary scratchpad.

I published a preprint on Zenodo: Research grounding for a bilateral venture capital model of PhD programs
Published:
A PhD system built on a 19th-century apprenticeship model is failing by nearly every empirical measure — ~40–50% attrition, depression rates six times the general population, and tenure-track placement below 15% in many fields — while venture capital has spent four decades perfecting bilateral contracts that manage exactly the risks PhD programs ignore: information asymmetry, moral hazard, hold-up, and misaligned incentives. The literature across economics, education policy, signaling theory, and AI research converges on a striking conclusion: the structural tools to fix the PhD already exist in VC contract design, but academia has never imported them. This research compendium maps the evidentiary landscape across six domains to ground the argument.
