✨ Explore this insightful post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: TL;DR: I built Snapstate to move business logic out of React components and into plain TypeScript classes. The result: stores you can test without React, components that only render, and a cleaner boundary between UI and application logic.React is excellent at rendering UI. It's less convincing as the place where the rest of the app should live.Over time, a lot of React codebases drift into the same shape: data fetching in useEffect, business rules inside custom hooks, derived values spread across useMemo, and mutations hidden…

Farmers have been fighting John Deere for years over the right to repair their equipment, and this week, they finally reached a landmark settlement. While the agricultural manufacturing giant pointed out in a statement that this is no admission of wrongdoing, it agreed to pay $99 million into a fund for farms and individuals who participated in a class action lawsuit. Specifically,…

Farmers melted down their cooking pots in backyard furnaces and reported spectacular numbers. The steel was useless. The crops rotted. Thirty million people starved. In 2026, every other company is having top down mandate on AI transformation. Same energy. Backyard Furnaces The rallying cry of the Great Leap Forward was 超英趕美 — surpass England, catch up to America. Every province, every village, every household was expected to close the gap with industrialized Western nations…

Seems like a daunting task at first, right? Writing drivers means you have to write Kernel code, and writing Kernel code is hard, low level, hard to debug and so on. None of this is actually true though. Writing a driver for a USB device is actually not much more difficult than writing an application that uses Sockets. This post aims to be a high level introduction to using USB…

🔥 Read this insightful post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Kalman Filter example
Let us begin with a simple example: a one-dimensional radar that measures range and velocity by transmitting a pulse toward
an aircraft and receiving the reflected echo. The time delay between pulse transmission and echo reception provides
information about the aircraft range \(r\), and the frequency shift of the reflected echo provides information about the
aircraft velocity \(v\) (Doppler effect).
In this example, the system state is described by both the aircraft range \(r\) and velocity \(v\).…

Below, we share how we study and track Muse Spark's scaling properties along three axes: pretraining, reinforcement learning, and test-time reasoning.Pretraining. The pretraining phase is where Muse Spark acquires its core multimodal understanding, reasoning, and coding abilities — the foundation that reinforcement learning and test-time compute build upon.Over the last nine months, we rebuilt our pretraining stack with improvements to model architecture, optimization, and data curation. Together, these advancements increase the capability we…

Today, Mac OS X joins that list. In this post, I’ll share how I ported the first version of Mac OS X, 10.0 Cheetah, to the Nintendo Wii. If you’re not an operating systems expert or low-level engineer, you’re in good company; this project was all about learning and navigating countless “unknown unknowns”.…

Designed for background workers, game AI, mundane task automation, and asynchronous logic. Instead of time.Sleep or infinite while loops, go-bt uses a cooperative multitasking model. Nodes return state instantly, yielding control back to the supervisor. Stateless Nodes: Nodes (Sequence, Selector, etc.) do not hold runtime state. All temporal memory and execution states live entirely within the generic BTContext[T]. The Magic Numbers: Every node's Run method returns exactly one of three integers: 1 (Success): The task is done…
