AI Navigation Revolution: Bearings Only Solves Distance Measurement Challenge

DeepMind's Bearings Only is a groundbreaking AI system that autonomously navigates using only bearing information (direction to target). This eliminates the traditional reliance on distance measurements, excelling in complex environments lacking distance data, such as underwater or space exploration. By learning from vast bearing datasets, the AI predicts target location and plans routes, revolutionizing underwater vehicle navigation and space exploration. This technology showcases AI's potential beyond navigation, suggesting new applications in challenging environments.

Looking Backward: A Utopian Novel Reflecting American Social Contradictions

Edward Bellamy's 1888 bestseller, *Looking Backward, 2000-1887*, depicted a utopian America in the year 2000, free from poverty and social unrest. The protagonist time-travels to experience this society where the state controls resources and equality reigns. However, the novel is not merely idealistic; it reflects the stark inequalities, worker exploitation, and political corruption of late 19th-century America. Bellamy offered a solution to these problems, albeit one that appears naive and utopian today. Despite its dated aspects, the novel's exploration of social conflict and the pursuit of justice remains relevant.

Jujutsu VCS: Streamlining Code Merges and Branch Management

This article presents a highly efficient workflow for managing code merges and branches using the Jujutsu version control system. The author introduces a 'megamerge' approach: create a merge commit as a working area, and then use `jj squash` to integrate changes into the appropriate parent commits upon completion of each task. Further streamlining is achieved with the `jj absorb` command, which automates this integration process. This workflow allows developers to seamlessly manage multiple parallel streams of work, significantly boosting efficiency, particularly when tackling large, long-running upgrades. The author contrasts this with the complexities of achieving the same results with Git.

Spline Distance Fields: A Novel Terrain Generation Technique

2025-01-06

To overcome limitations in the Tangerine game engine, the author developed a CPU ray tracer called Star Machine and a racing game prototype, Rainy Road. Rainy Road requires an efficient and compact terrain rendering system capable of handling roads and other terrain features defined by splines. The author introduces a novel terrain generation technique using spline distance fields. This technique utilizes splines to generate terrain surfaces by calculating the distance of a point to the nearest spline and its normal vector to determine elevation. This avoids the limitations of traditional heightmaps and supports procedural object placement. The technique is under active experimentation and research, with exploration of improved interpolation strategies and the use of sparse point clouds.

Engineer Builds Camera That Ignores Perspective, Sees Through Walls

Shane Wighton, the creator of the YouTube channel Stuff Made Here, has engineered an incredible camera that defies perspective and can even see through walls. Instead of a traditional lens, this camera uses a sophisticated mechanical system to scan a scene one pixel at a time, building a complete image. By utilizing a spinning gantry and a precisely controlled mirror, the camera moves in 3D space, capturing multiple views to reconstruct the final image. This allows it to create images without perspective, achieve reverse perspective, and even see around objects, showcasing an astonishing feat of engineering and imaging technology.

Human Thought Speed: A Mere 10 Bits Per Second

Caltech researchers have discovered that human thought processes are surprisingly slow, operating at a mere 10 bits per second—significantly slower than our sensory systems' billion bits per second input rate. This study presents a paradox: why is our thinking so slow? Researchers speculate this may stem from the evolution of our brains from simple navigational systems, processing information sequentially rather than in parallel. This finding challenges some science fiction concepts regarding brain-computer interfaces, suggesting even neural interfaces would be limited by our inherent 10-bit-per-second processing speed.

The Open Source Maintainer Crisis: Burnout, Pressure, and an Uncertain Future

The 2025 State Of Open conference highlighted the plight of open source maintainers: volunteers pour countless hours into projects with little support, leading many to quit or consider quitting. The resignation of Asahi Linux lead Hector Martin due to burnout and demanding users exemplifies this crisis. Maintainers face pressure from users, endless requests, and occasional negativity. Even with minimal corporate sponsorship, the demands far outweigh the support. Surveys reveal many maintainers considering quitting, and many projects may become unmaintained. The problem isn't solely financial; it also requires more contributors to share non-coding tasks like community management and fundraising. But change needs a catalyst—perhaps a major project collapse will finally convince people that paying open source maintainers is crucial.

Ancient Genomes Solve Indo-European Language Origins Mystery

A groundbreaking study involving 91 researchers analyzed 314 ancient genomes, finally unraveling the mystery of Indo-European language origins. The research revealed a significant genetic divergence between eastern and western Mediterranean Indo-European populations during the Bronze Age, consistent with Italo-Celtic and Graeco-Armenian linguistic models. Spanish, French, and Italian populations received steppe ancestry from Bell Beaker groups, while Greek and Armenian groups acquired ancestry directly from Yamnaya populations. Strontium isotope analysis further confirmed active mobility patterns during the Bronze Age. This study provides compelling genetic and linguistic evidence for the origins of Indo-European languages and challenges alternative linguistic hypotheses.

Making Unsafe Rust Safer: Verification Tools for Unsafe Code

Making Unsafe Rust Safer: Verification Tools for Unsafe Code

Rust's popularity stems from its ability to eliminate memory and concurrency errors at compile time, but its `unsafe` code blocks can bypass these checks. This article explores tools for verifying unsafe Rust code, including code called from C or C++ libraries. It introduces runtime error detection tools—sanitizers—and Miri, an interpreter that deterministically finds undefined behavior. Sanitizers detect out-of-bounds memory access, data races, and more, while Miri provides more precise error reporting with code snippets. However, Miri currently doesn't support code called via FFI from C/C++, necessitating the use of C/C++ compiler sanitizers in such cases. These tools enhance the safety and reliability of Rust code, even when dealing with `unsafe` code or interacting with C/C++ libraries.
