DeviceTree For Hackers: Intro

A leaked Raspberry Pi DeviceTree file reveals hardware details of the Pi Zero 3W, including a BCM2711 chip, PCIe support, a power button, an extra LED, and an eMMC option. This serves as the entry point for an intro to DeviceTree, the format that tells Linux kernels what CPU, drivers, and interfaces a board has. DeviceTree source files (.dts, .dtsi) compile into binary .dtb/.dtbo files the kernel reads, and the device-tree-compiler package handles both compiling and decompiling. The guide covers includes, base files, and overlays, recommends learning from Raspberry Pi's overlay directory and repos like Radxa and Armbian, and warns that LLMs sometimes hallucinate overlay properties.

GTA.js, a reimplementation of the 1997 Grand Theft Auto engine in JavaScript and WebGL

Dự án GTA.js tái tạo lại engine của game Grand Theft Auto năm 1997 bằng JavaScript và WebGL, có thể chơi tại gtajs.wtf. Đây là bản reimplement chứ không phải emulator, nên một số vật lý và animation khác với bản gốc, nhưng engine nhiệm vụ chính xác dựa trên tài liệu mtd.doc. Tác giả sử dụng Gemini AI để triển khai hầu hết các tính năng, tham khảo tài liệu mở, ghi chú cộng đồng và trí nhớ cá nhân về game. Hiện tại game đã chơi được nhưng cảnh sát (cops) vẫn chưa được implement.

Lập trình viên nên đọc bài này để khám phá cách tái tạo lại engine game cổ bằng JavaScript và WebGL từ con số không.

Undervolting my Ryzen 7 5800X3D taught me that lower voltage doesn't have to mean lower performance

Turns out, it isn't just about lowering temperatures.

Saving A Vintage High-Voltage Power Supply From The Scrap Heap

A Fluke Model 407 high-voltage power supply gets rescued from the scrap heap and diagnosed on video. Mr Carlson powers it up safely using an isolated transformer and a current-limited variac, avoiding the risk of full power on old components. The vacuum-tube-and-circuit-board unit shows no visible damage but its output misbehaves. Using the original schematics, he traces the fault to a single faulty capacitor in the feedback loop that keeps output voltage constant.

Quasi-Logarithmic Kitchen Timer

Like some of you, we have several kitchen appliances with integrated digital timers.

SparkFun IoT RedBoard ESP32-P4 – Arduino UNO-like ESP32-P4 v3.x development boards with WiFi 6 or PoE options

SparkFun introduced two new development boards called IoT RedBoard, both based on the ESP32-P4 v3.x (ESP32-P4X) and compatible with the Arduino UNO R3

Finding Xanadu: Inside a JRPG classic translation 15 years in the making

Plus this oversized issue features interviews for two more human-made fan translations that prove the world hasn't fully gone to slop.

The PlayStation 3 briefly made buying a console a way to buy a Linux computer

It was a little too good at what it did, though.
