Putting different fields together, to see what emerges.
Writing about finance, data, AI, and a few things that resist classification.
源Fields
I work where finance, data and design meet — and twenty years in, I'm more certain than ever that the interesting things live at the confluence, not in any single channel.

支The Open Lab
A semi-open lab for exchanging ideas, asking better questions, and sharing thoughts before they are fully formed.
下Classes
Occasional classes on AI, data and useful tools. Less theory for theory's sake; more things you can actually take away and use. Members receive class discounts and priority access.

Excellent workshop that enable myself to turn ideas in my mind for years into actual tools, without the need of any developers or engineers! The workshop lays the foundation for plenty of future use cases too - recommended for everyone who is afraid of tech and taking their first step to create something on your own!
很精彩的工作坊！讓我終於可以把一些在腦海裡放了多年的想法，真正做成可用的工具，而且不需要依靠開發人員或工程師。 課堂亦為日後很多不同的應用打好基礎。很推薦給對科技有點卻步、但想踏出第一步，親手把想法做出來的人。
I really enjoyed the Vibe Coding course. I came in with lots of ideas but very little confidence that I could actually build them myself. The course changed that.
What I found most valuable was learning by actually building, rather than spending too much time on theory. By the end, I had built a working MVP and, more importantly, understood how to approach an idea: start small, define what you want it to do, build, test, and iterate.
It made building with AI feel much more accessible to someone who isn't a traditional developer. I left the course not just with something I'd built, but with a long list of things I now want to try building next.
我很喜歡這次 Vibe Coding 課程。來上課之前，我腦裡有很多想法，但一直沒有太大信心，覺得自己真的可以親手把它們做出來。這堂課改變了這一點。 我覺得最有價值的地方，是透過實際動手做來學，而不是花太多時間停留在理論。到課堂結束時，我已經做出一個可以運作的 MVP；更重要的是，我開始明白應該怎樣把一個想法一步步做出來：先從小處開始，定義清楚想做到甚麼，然後建構、測試，再持續迭代。 對一個不是傳統開發者的人來說，這堂課令用 AI 動手做東西變得容易接近得多。離開課堂時，我帶走的不只是自己做出來的作品，還有一長串接下來想繼續嘗試做的東西。
Horris is highly experienced in the field. He presents complicated and abstract AI concepts in a simple, accessible way, using plenty of live examples. With his guidance, I’ve already started exploring different business ideas using the agent I built, and I highly recommend this course.
Horris 在這個領域擁有豐富經驗。他善於運用大量即場示範，以簡單易明的方式講解複雜而抽象的 AI 概念。在他的指導下，我已經開始利用自己建立的智能代理，探索不同的商業構想。我非常推薦這個課程。
Horris 最特別嘅地方，唔單止係佢「解釋得清楚」。佢既有行業專家級嘅深度，又有好強嘅教學同表達能力，可以將複雜概念講得簡單，同時保持內容準確而有深度。
What makes Horris stand out is not simply that he “explains things clearly.” He combines the depth of an industry expert with a strong ability to teach and communicate, making complex concepts accessible without sacrificing accuracy or depth.
課程收穫很大，老師講解細緻，搭配現場實作練習，邊學邊操作更容易記住。上完課已能獨立完成基礎操作，整體課程含金量高，值得推薦。
I gained a great deal from the course. Horris explained everything thoroughly and combined his teaching with live, hands-on exercises, making it easier to remember by learning and practising at the same time. By the end of the course, I was able to carry out the basic tasks independently. The course was highly practical and valuable, and I would recommend it.
上ht 堂個腦要轉得夠快，所有野都係about logic. 但就因為係教logic and foundations, 先會一理通百理明，了解左d tools背後點操作，隨意轉tools都唔會唔識。
上過2堂都講左好多背後原理，每堂都學到tool 實操到，做到自己想要嘅野而唔係齋講theory: 1st lesson AI agent, 2nd lesson vibe coding. 就因為唔係只教tool 入面內容所以就算落左堂自己trial and error, 都唔會一頭霧水。同埋有問題個陣你真是好helpful and can resolve those problems.
但就真係要有基本知識先catch 到😂
HtPi classes really make your brain work — everything comes back to logic. But because the focus is on logic and foundations, once you understand the underlying principles, everything starts to click. You understand how the tools work behind the scenes, so even when you switch tools, you won’t feel lost. I’ve taken two classes so far, and both covered a lot of the underlying concepts while still being very hands-on. In every class, you actually build something you want rather than just talk about theory: the first class was on AI agents, and the second was Vibe Coding. Because the classes don’t just teach you where to click inside a particular tool, you can continue experimenting through trial and error afterwards without feeling completely clueless. And whenever I ran into problems, you were really helpful in resolving them. That said, you do need some basic knowledge to keep up 😂
