The content introduces uvm32, a minimalist, dependency-free virtual machine sandbox designed for microcontrollers and resource-constrained devices, implemented in a single C file without dynamic memory allocations. It runs on systems like STM32L0 with a low footprint (under 4KB flash and 1KB RAM) and serves as a RISC-V emulator. Uvm32 is aimed at executing custom script-like logic rather than simulating hardware. It provides tools for building efficient code and a simple VM host example

A team developed a comprehensive virtual reality (VR) setup for rats to play DOOM, featuring a motion-tracked treadmill ball, a panoramic headset, an input trigger, and a reward circuit. All components, including designs and software, are open-sourced for others to replicate. The project originated in New York with initial training of rats by Viktor, and after a pause, interest led to a more advanced version (v2) developed with engineers and collaborators to enhance documentation and accessibility. The hardware enables

The content describes the design principles behind the fish shell, which aim to balance user-friendliness with expressiveness, while adhering to POSIX standards where feasible. The fish design has three main goals: to enable all functionalities available in other shell languages, to be user-friendly without sacrificing power, and to follow POSIX guidelines as much as possible. Several specific design principles are highlighted to support these goals: 1. **Limited Orthogonal Features:** The shell should have a minimal set of distinct features to

The content provides a personal account of the author's experience with durable execution and its connection to task queues and orchestration systems, particularly in the context of managing Kubernetes deployments at Porter, a company where the author was CTO. Initially skeptical and unsure about the relevance of Temporal—an orchestration tool—the author struggled to understand its principles despite recognizing its potential benefits. Over time, after leaving Porter, the author conducted more in-depth research into durable execution platforms, even creating an open-source project with Temporal. The post

In May, OpenAI attempted to acquire Windsurf (formerly Codeium) for $3 billion, but the deal ultimately fell through. Recently, Anthropic acquired Bun, an open-source JavaScript runtime, although they could have built on it for free. This move suggests that companies in the AI sector are seeking to acquire engineering talent rather than replace them, contradicting the narrative that programming jobs are dying due to AI. The author argues that while AI has the potential to automate many programming tasks, the

Researchers have developed a new strain of the fungus Fusarium venenatum using CRISPR gene editing, enhancing its efficiency, nutrition, and sustainability compared to its natural variant. This fungal strain, known for its meat-like flavor, was modified by removing two specific genes: one that thickened the cell walls, improving digestibility, and another that optimized its metabolism. The resulting strain, FCPD, produces protein 88% faster and uses 44% less sugar. This innovation significantly lowers greenhouse gas
