Exbody2: High-Fidelity Whole-Body Motion Mimicry in Humanoid Robots

2024-12-18

Researchers have developed Exbody2, a generalized whole-body tracking framework enabling humanoid robots to perform expressive motions with human-like stability. Trained in simulation using Reinforcement Learning and then transferred to the real world, Exbody2 decouples keypoint tracking from velocity control. It leverages a privileged teacher policy to distill precise mimicry skills, achieving high-fidelity replication of dynamic movements such as running, crouching, and dancing. Experiments on two humanoid platforms demonstrate superior performance compared to state-of-the-art methods, providing practical guidelines for advanced whole-body control in humanoid robotics.

OpenAuth: A Universal, Self-Hosted OAuth 2.0 Server

2024-12-17

OpenAuth is a universal, standards-based, open-source authentication provider. Deployable as a standalone service or embedded within existing applications, it's framework-agnostic and runs on Node.js, Bun, AWS Lambda, or Cloudflare Workers. Adhering to OAuth 2.0, OpenAuth offers a customizable, themeable UI. Unlike most open-source auth solutions which are libraries, OpenAuth is a centralized server designed for easy self-hosting on your infrastructure. It intentionally omits user management, instead providing callbacks for custom user lookup/creation. Data storage is minimal (refresh tokens, etc.) using a simple KV store (Cloudflare KV, DynamoDB). A pre-built UI is available, but you can easily customize or replace it entirely. Created by the SST team, OpenAuth simplifies authentication for your applications.

Making Unsafe Rust Safer: Verification Tools for Unsafe Code

2024-12-17

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.

The BYOJS project champions building web applications with core JavaScript, rather than relying on heavy frameworks. While frameworks and languages like TypeScript are popular, BYOJS argues that building efficient web apps using the core JS language is a lost art. It encourages using loosely-coupled libraries instead of tightly-coupled frameworks, advocating for choosing the least powerful tool that gets the job done and prioritizing concise code. The project provides helpful utilities such as a simple key-value storage API, an asynchronous event emitter, a modal wrapper, and more. All code is MIT licensed.

Network Security Breakthrough: Trapping Intruders in a 'Network from Hell'

2024-12-17

Researchers at the University of Oulu's SensorFu team have developed a novel network security defense system inspired by the LaBrea tarpit technique. The system intercepts ARP requests and delays SYN-ACK responses, creating a multitude of virtual devices on the network to confuse intruders. This forces attackers to waste significant time identifying real devices, providing administrators with crucial time to patch vulnerabilities. Tests showed the system extends scan times to hours, drastically reducing attack success rates. Lightweight, efficient, and easy to deploy, this system offers robust network protection for organizations of all sizes.

Startup Failure After 3 Years: Founder Open-Sources All Code

2024-12-17

After three years, Dylan Huang's developer tools startup, Konfig, has shut down. Konfig focused on simplifying API integrations, with its core product being an SDK generator alongside API documentation and testing tools. Despite gaining some early traction, the company failed to achieve hyper-growth due to challenges in securing contracts and low pricing. A pivot to a B2B SaaS AI product also proved unsuccessful. Now, Huang is open-sourcing Konfig's entire codebase – including the core product, failed pivots, and various supporting scripts – hoping it will be beneficial to others. While the startup ended in failure, Huang emphasizes the invaluable lessons learned.

RTO Mandates Lead to Tech Talent Exodus, Study Finds

2024-12-17

A study tracking over 3 million employees at 54 S&P 500 high-tech and financial firms reveals that return-to-office (RTO) mandates are causing companies to lose top talent and struggle to find replacements. The research found a 14 percent average increase in employee turnover after RTO policies were implemented, with senior and skilled employees more likely to leave. Women experienced nearly three times the attrition rate of men. Furthermore, RTO mandates prolonged hiring times and increased costs. Companies' attempts to enforce RTO policies through surveillance tactics, such as VPN tracking and badge swipe monitoring, fueled employee resentment and furthered the exodus. The study suggests that RTO mandates reflect a culture of distrust and ineffective management, leading to decreased employee engagement.

Starlink Sells Out in Zimbabwe Amidst High Demand

2024-12-17

Starlink's high-speed satellite internet service quickly sold out in Zimbabwe within weeks of its launch, driven by the country's slow, unreliable, and expensive traditional internet infrastructure. High demand led to sell-outs in major cities like Harare, and even spread to other African countries. Despite higher initial costs, Starlink's unlimited data and superior speeds are proving attractive to many, forcing local providers to lower their prices. While currently facing capacity issues in urban areas, Starlink's potential in rural and underserved regions is significant, boosting related industries such as installation services and accessory sales.

Attention as Electromagnetic Field Line Management: A New Model of Consciousness

2024-12-17

Qualia Research Institute proposes a novel model of attention, conceptualizing it as the management of dynamic patterns in the brain's electromagnetic field. By simulating electric field lines arising from weighted sums of harmonic oscillations, researchers demonstrate how attention controls charge density by modulating underlying resonant modes, explaining seemingly random fluctuations and drifts in attentional behavior. This model also offers a potential explanation for psychedelic experiences, suggesting that psychedelics disrupt the normal flow of attention by altering the configuration of harmonic modes. The research provides a new lens for understanding consciousness and developing novel neuro-interventions, such as inducing exotic states of consciousness by non-invasively perturbing the phase locking of attention.

A Glimpse into OS/2's Built-in Virtualization

2024-12-17

This blog post explores the surprisingly advanced built-in virtualization capabilities of OS/2 2.1 from 1993. The author demonstrates OS/2's ability to load and execute disk images, much like modern hypervisors, by creating a simple VGA mode program and running it in DOSBox, QEMU, and OS/2's own virtual environment. OS/2 can even run images that aren't true bootable DOS floppies, using VMDISK to create an image file and running it in fullscreen or windowed mode within OS/2. This functionality, remarkable for 1993, is essentially a built-in QEMU, prompting the author to consider the further potential of OS/2's virtualization features.

This article explores key events and misconceptions surrounding the development of highways after World War II. It clarifies that Germany's Autobahn was not initially designed for military purposes, but rather to stimulate the economy and enhance national prestige. While Allied forces utilized the Autobahn in the later stages of WWII, this wasn't its original intent. The article debunks the myth that the US Interstate system was designed with one mile in five being straight and level for emergency bomber landings, explaining its true purpose was civilian benefit and economic development, although it also served military needs, such as troop movement and industrial production. Finally, the article reviews post-WWII attempts and exercises by various militaries to utilize highways as emergency runways for aircraft, highlighting their limitations and ultimate replacement by dedicated airfields.
