This repository contains experimental code for thread-like processes that blend the Posix process model with multi-threading, enabling zero-copy access to pointer-based data structures. The code has limitations, including no support for debugging, ptrace, or signals, and requires careful memory management due to independent libc instances for each threadproc.

The user designed an I/O co-processor called BIO for the Baochip-1x SoC, which is a more efficient alternative to the Raspberry Pi's PIO. The BIO uses a RISC-V 32-bit core and a set of FIFO-registers to achieve determinism and flexibility, and can be used for various I/O tasks such as DMA and SPI bit-banging.
Years of countless pours led me to the question “Is this really a pint? They say so, but really?” The findings gave rise to the Pint Patrol, a grassroots movement that could change how Americans are served their beer, wine, and cider—toward righteous honesty. This article documents the initial discovery and the inception of the movement.

They also provide tips for staying organized, reading efficiently, and avoiding burnout, and encourage researchers to view their work as a ...
Companies using Dspy report benefits like quick model testing and maintainable systems, but implementing Dspy-like patterns can be hard and lead to worse versions. Dspy forces you to think about abstractions upfront, which can be a steep learning curve, but is necessary for complex AI systems.
The user built an AI receptionist named Axle for their brother's luxury mechanic shop to answer customer calls and provide accurate information about prices, hours, and policies. The system uses Retrieval-Augmented Generation (RAG) and a custom-built knowledge base to ensure accurate and grounded responses, and can also collect callbacks for unknown questions.
The more I learn about the systems I depend on every day, the more I'm convinced that everything in compsci is a dumpster fire that we collectively refuse to extinguish. It's a social problem - and, of course, everyone is trying to solve it with tech. "dmi went into a bit of a different direction than usual with this one! she asked me to issue a Content Warning for Capitalism and ...

The article discusses how collaboration has become a misguided obsession in the modern tech industry, leading to a lack of accountability and productivity. It argues that most complex work is done by individuals or small groups with clear authority and accountability.
The user argues that while AI helps with precision in coding, it also creates an illusion of precision, which can lead to bugs and complexity issues when scaled up. The user believes that good code is not just about producing working software, but also about creating beautiful, well-structured abstractions that help master complexity, and that AI will be a boon for coding, not a replacement for it.
Manyana is a project that presents a coherent vision for the future of version control using CRDTs, which provide eventual consistency and informative conflict markers. It offers a better design for version control, including permanent line ordering, informative conflicts, and preserved history, making it a promising proof for CRDT-based version control.

Intoxalock is experiencing downtime after a cyberattack on March 14, affecting breathalyzer devices used by 150,000 drivers. The attack has caused calibration delays, leaving some drivers unable to start their vehicles.
The user created a low-budget electromagnetic fault injection (EMFI) tool using a piezo-electric lighter and an antenna wire to induce memory errors in a laptop's DDR bus, then used this tool to write a local-privilege-escalation exploit for CPython. The user then used a similar EMFI tool to create a reliable exploit for Linux, allowing them to gain root access by corrupting page tables and ...
The user loves NixOS for its deterministic and reproducible package manager, allowing them to define and rebuild their operating system from a single source of truth. This approach makes experimentation cheap and safe, and the user appreciates its stability, predictability, and coherence across platforms.
