A Tiny Forth for the 6502: Under 600 Bytes

This article details a highly minimized Forth implementation for the 8-bit 6502 CPU, achieving a size of under 600 bytes. The author compares two interpreter models: Direct Threaded Code (DTC) and Minimal Threaded Code (MTC), opting for DTC for its smaller size. The project focuses on size over performance, aiming to verify standard DTC against MTC variations. The resulting Forth includes core primitives and is tested with `my_hello_world.FORTH`, demonstrating functionality.

Preschoolers' Reasoning Skills Surprise Researchers

A University of Montreal study reveals that preschoolers (ages 3-5) demonstrate surprisingly sophisticated reasoning skills when categorizing toys. They go beyond simple binary classification, creating multiple categories based on various criteria and even adjusting their criteria mid-task, showcasing complex mathematical reasoning. This challenges previous understandings of child cognitive development and offers new insights for early childhood education.

The Future of Coding in the Age of AI

A tweet by Replit's CEO suggesting that learning to code is no longer necessary sparked a debate. The author, a software engineer with 15 years of experience, reflects on the implications of AI-powered coding tools. While acknowledging the efficiency gains from AI, he cautions against over-reliance, arguing it diminishes understanding and leaves programmers vulnerable to vendors. He advises beginners to build a strong foundation in coding fundamentals to remain competitive. AI boosts productivity, but it can't replace solid coding skills.

Debugger as REPL: IntelliJ IDEA's Run to Cursor and Quick Evaluate Expression

2025-03-28

Tired of traditional debuggers, especially gdb and lldb's limitations with native code, the author discovered a powerful workflow in IntelliJ IDEA. Combining "Run to Cursor" and "Quick Evaluate Expression" transforms the debugger into a REPL. "Run to Cursor" executes the program to the cursor's position, while "Quick Evaluate Expression" lets you evaluate expressions (even newly typed code!) within the current stack frame. This approach replaces the line-by-line stepping with a more experimental, two-dimensional interaction within the editor, leveraging code completion and offering a significantly more efficient debugging experience.

Claude Controls Elektron Digitone: AI-Powered Music Production

A Model Context Protocol (MCP) server, Digitone MCP, enables Claude and other MCP-compatible LLMs to interact with and control Elektron Digitone synthesizers via MIDI. Currently, only the Wavetone machine is supported, but more will be added soon. The project uses Python 3.10+, requiring the `uv` package and the Claude Desktop app for full integration. By configuring the MCP server in `claude_desktop_config.json`, Claude can control the Digitone in real-time, enabling AI-assisted music creation. The library features a clean, object-oriented architecture with base controllers, specialized controllers, MCP tools, and a MIDI interface, utilizing FastMCP, Pydantic models, and mido for efficiency and reliability.

Say Goodbye to Dependency Headaches: Simplifying Python Script Distribution with uv and PEP 723

2025-03-28

Tired of managing external library dependencies for your single-file Python scripts? This article shows how uv and PEP 723 make distribution a breeze. By embedding dependency metadata directly into your script, uv eliminates the need for `requirements.txt` and complex package managers. It automatically creates isolated virtual environments, installs dependencies, and runs your script—all without manual intervention. Adding a shebang makes execution even easier, directly launching your script from anywhere.

Extending Futhark's Backend: Not Easy, But Not Impossible

2025-03-28

This post delves into the complexities of adding a new backend to the Futhark compiler. Futhark uses a staged compilation process: the frontend parses and type-checks, the middle-end optimizes and transforms, and the backend translates the intermediate representation (IR) to target code. Backend implementation isn't a simple tutorial; it involves multiple IR dialects and a deep understanding of internal APIs. The author suggests choosing the appropriate IR dialect based on the target language's level of abstraction and leveraging existing infrastructure to simplify development. The ultimate goal is a new backend invokable via the command line.

Running Go Code on a PS2: A Hackery Adventure

The author embarked on a challenging project: running Go code on a PlayStation 2. Go's lack of native PS2 support necessitated using the TinyGo compiler and the ps2dev SDK. The author overcame compatibility issues between Go and the PS2's Emotion Engine CPU (based on MIPS R5900), including differences in the N32 ABI and 64-bit instruction sets. A significant hurdle was the missing DDIVU instruction, solved by modifying the TinyGo compiler. A simple Go program was successfully run and verified on the PCSX2 PS2 emulator. Future plans include improving floating-point support and creating a custom LLVM MIPS CPU.

Apple Needs Another Snow Leopard Moment

Apple's 2009 Mac OS X Snow Leopard, known for its refinement and optimization, stands as one of its most stable releases. However, current MacOS and iOS systems are plagued by bugs and poor design choices, such as broken copy-paste in Messages and a confusing System Settings interface. The author urges Apple to emulate Snow Leopard, undertaking a major system cleanup and optimization to address these issues instead of solely focusing on adding new features. This would enhance user experience, solidify Apple's position, and maintain competitiveness even amidst the fierce AI race.

Don't Let Self-Serve UIs Fool You: They Aren't Always a Silver Bullet

2025-03-27

This article explores the pros and cons of building self-serve UIs for accessing internal systems. While simplifying configuration seems appealing, for complex tasks, self-serve UIs can be counterproductive. They don't solve underlying engineering problems and can mask risks, leading to errors and security vulnerabilities. The author suggests that before building a self-serve UI, one should first delve deeper into the root cause of the problem and improve the system itself, rather than just relying on superficial simplification.

Clean: An Embedded DSL and Formal Verification Framework for ZK Circuits in Lean4

2025-03-27

Researchers have developed Clean, an embedded domain-specific language (DSL) and formal verification framework in Lean4 for building zero-knowledge (ZK) circuits. ZK circuits are prone to bugs, and Clean aims to improve correctness by allowing users to define circuits in Lean4, specify their desired properties, and formally prove them. This project is part of the zkEVM Formal Verification Project, aiming to provide infrastructure and tooling for formal verification of zkEVMs. Clean supports four basic operations for defining circuits: witness, assert, lookup, and subcircuit, and offers a monadic interface for enhanced usability. At its core is the FormalCircuit structure, which tightly packages—in a dependently-typed way—the circuit definition, assumptions, specification, soundness, and completeness proofs. Large circuits can be formally verified by recursively replacing subcircuit constraints with their (formally verified) specifications. The framework has successfully verified simple circuits like 8-bit addition, with future plans to add more low-level gadgets, define common hash function circuits, and build a formally verified minimal VM for a subset of RISC-V.
