If you have ever wired a classifier into an app, you know the model is the easy part and the plumbing around it is where the weekend goes. This is a w
I run a small research site for Indian markets. I pulled every bulk and block deal the NSE has disclosed since January 2023, about 90,000 rows, to see

A keyword scorer is the cheapest filter you can put in front of an LLM. You write terms, you give them weights, you sum the matches, and anything over
TypeSafe Jev is the hosted model that introduced System One models on September 15, 2026: you send a state and typed questions, and it returns answers

A coding agent can produce a large branch faster than a human can build a reliable mental model of it. That changes the review problem. The limiting f
I have used Git every working day for about fifteen years and I could not have told you, in any detail, what it puts on disk. I knew the shape of the
Keep the join in place until quote, null, and newline bytes match. A passing check on row counts does not protect those bytes. Extract one helper only

TL;DR — Most teams size LLM serving around FLOPs and tokens-per-second, but the actual constraint is KV-cache memory. Once you model inference as a m
Laya is an open-weight decision model that turns a piece of state and a set of typed questions into structured answers, such as a category, an ordered

A scheduled drafting agent is a producer. The thing that consumes what it produces is a person, and a person does not run on a cron. That mismatch is
TL;DR — I rebuilt my Chinese A-share signal study on 3,145 main-board stocks × 622 trading days (2024-01-26 → 2026-09-18) = 904,775 pattern-labelled s
I wanted my own articles as audio: something I could listen to on a walk, as a conversation between two voices rather than one voice reading. Not a cl
List comprehension is a concise way to create new lists by applying an expression to each item in an existing iterable like a list, tuple or range. It
Building an AI agent is easy. Building the system around it is where things get complicated. You can create an agent in a few lines of Python. Then y
