We Built Bank-Grade Security for Immigrants. Here’s What Broke First.

⋅

Picture this: You just landed in the US. You’ve got a job, a signed lease, and your phone. But you have zero credit history. No SSN yet. And absolutely nobody is walking you through this financial maze. A coworker swears by this finance app, so you download it. You try linking your bank. It fails. The error message is in English. There’s no clear retry path. You close the app. You’re done. Probably for good. That isn’t just […]

From Prompts to Harnesses: How AI Engineering Has Grown Up

⋅

I want to talk about something that has been quietly changing how serious developers build with AI tools. It did not happen overnight. There was no single blog post or conference talk that kicked it off. It happened gradually, the way most good ideas in software do. Developers ran into the same problems over and over again, figured out better ways to solve them, and those better ways eventually got names. The names are: prompt engineering, context engineering, and harness engineering. […]

Africa Isn’t Catching Up to the West in Fintech. It Left a While Ago

⋅

A colleague said something to me last year that I haven’t quite been able to shake. We were in a conversation about emerging markets, and he said, very genuinely, “It’s brilliant what’s happening in Africa with fintech. They’re really starting to catch up.” He meant it kindly. I didn’t correct him in the moment. But I’ve been thinking about it ever since, because the framing is so wrong it’s almost the opposite of what’s true. Africa isn’t catching […]

AI data centers head for the ocean

AI data centers head for the ocean

⋅

Read Online | Sign Up | Advertise Good morning, {{ first_name | AI enthusiasts }}. AI’s land grab is running into walls — literal ones, in the form of an angry public fed up with data center constructions in their cities. Oregon-based startup Panthalassa is taking things offshore instead, with Peter Thiel leading a new $140M round for floating structures that turn ocean energy into the compute AI companies are all scrambling for more of. In today’s AI […]

Eduard Khemchan and the Limits of Short-Term Market Thinking

⋅

Eduard Khemchan does not ignore short-term market movements. He places limits on how much they influence capital decisions. That distinction defines his approach. In modern markets, short-term signals dominate attention. Price movement, liquidity shifts, policy reactions, and technological narratives create a constant stream of information. The speed at which these signals move has increased significantly. Digital platforms compress reaction time. Participation widens. Capital rotates quickly between themes. The result is an environment where immediacy often replaces perspective. Eduard […]

Why Gradient Descent Zigzags and How Momentum Fixes It

Why Gradient Descent Zigzags and How Momentum Fixes It

⋅

Gradient descent has a fundamental limitation: on most real-world loss surfaces, it is inefficient. When the surface has uneven curvature—steep in one direction and flat in another, which is common in practice—the algorithm struggles to make consistent progress. A high learning rate helps move faster along the flat direction but causes overshooting and oscillations along the steep direction. Reducing the learning rate stabilizes the updates but significantly slows convergence. This trade-off is not rare; it is typical behavior […]

Intersection of RL and Psychology

⋅

Looking for others interested in both Psych and RL. Been working on what was meant to be a basic human model, turned into what could be a better understanding of humans in general.

El programador que dejó de programar: anatomía de una transformación

El programador que dejó de programar: anatomía de una transformación

⋅

Desde la irrupción de ChatGPT, el número de desarrolladores ha crecido entre un 18% y un 50% dependiendo de la métrica. Más automatización, más empleo. La paradoja es evidente, y tiene una explicación, aunque no sea la que muchos esperaban. Porque lo que está ocurriendo no es una desaparición, sino algo bastante más interesante: una redefinición profunda de lo que significa «ser programador». Porque, en efecto, si hay un ámbito en el que los modelos de lenguaje tienen […]

Vector Search Done Right: Best Practices, Qwen3 Dimension Control, and Why Reranking Is Non-Negotiable Three things your RAG pipeline on Databricks needs to get right — and why most pipelines get at least one of them wrong. The Problem With “Good Enough” Retrieval RAG pipelines fail quietly. When your agent gives an incomplete or wrong answer, the LLM gets the blame — but more often the problem is upstream. The wrong context was retrieved. The index was built with defaults that prioritise convenience […]
