The rosenbridge backdoor is a hidden CPU core in some VIA C3 processors that allows unprivileged code to access kernel data. It can be closed by running a utility on baremetal, but an attacker with kernel access can still re-enable it.
Thijs de Buck, an MRI physicist, built a speed and distance tracker for his hamster Mollie's wheel, uploading data to Mollie's Strava account. Mollie has logged over 10 kilometers per night, with a record of 10.8 kilometers, and has gained thousands of likes and followers on Strava.

Knowledge Workers are increasingly disillusioned with their careers, feeling a sense of existential angst and questioning the point of their work, as AI threatens to automate many tasks and make their jobs seem meaningless. This disillusionment could lead to a paradigm shift, where workers start to value the human experience of work over the appearance of productivity, and seek to create ...
Researchers are finding the slowest single instructions on CPUs by using various techniques such as starving the PCIe fabric, loading large amounts of data from high-latency MMIO regions, and leveraging microcode assists.
The ao486 project is an x86 compatible Verilog core implementing a 486 SX with a SoC capable of booting Linux and Windows 95. It includes Sound Blaster 2.0 and VGA support, with a NIOS2 processor for managing components and displaying On Screen Display.
A free wildfire tracking service is now available using Europe's Copernicus Browser, which provides high-resolution satellite imagery from the European Space Agency's Sentinel satellites. The service offers a new "wildfires" visualization layer that helps track active fires, burned vegetation, and burned landscapes.
NASA made a power-saving tweak to Voyager 2, called the 'Big Bang', to extend its lifespan by a year. The tweak reduced power requirements by turning off non-essential devices and using lower-power alternatives to keep the spacecraft warm.
SuperDuper 4 is a major update with a new design, faster performance, and more features. It offers improved copy jobs, scheduling, and support for various file systems, as well as new shortcuts and rules for customization.

RAM prices are expected to rise due to sold-out 2027 capacity to AI companies through long-term purchasing agreements. NAND storage is also in high demand, with SSD prices increasing, potentially leading to further price hikes in the near future.
Companies are facing exponentially growing costs from AI coding tools, but several large-scale adopters have converged on approaches to manage costs while maintaining access to AI tooling. Techniques such as adopting newer, more efficient models, using meta-harnesses, and routing work to the cheapest capable model can help reduce costs while preserving productivity gains.
Nixpkgs core team disbanded after 10 months, leaving a legacy of governance reforms and new committer onboarding. Key achievements include process reforms, new committer additions, and infrastructure upgrades.
In 1986, a Romanian cave system was discovered sealed off from the outside world for 5.5 million years, containing a thriving community of life powered by chemosynthesis, not sunlight. This underground ecosystem, known as Movile Cave, has been a significant scientific discovery, providing insights into life's adaptability and potential existence beyond Earth.
Tell Abu Hureyra (Arabic: تل أبو هريرة) is a prehistoric archaeological site in the Upper Euphrates valley in Syria. The tell was inhabited between 13,300 and 7,800 cal. BP[1] in two main phases: Abu Hureyra 1, dated to the Epipalaeolithic, was a village of sedentary hunter-gatherers; Abu Hureyra 2, dated to the Pre-Pottery Neolithic, was home to some of the world's first farmers.[2] This ...
Ralph Merkle improved the Lamport-Diffie one-time signature by reducing storage space and introducing the Merkle tree, which allows for efficient authentication of messages without storing all public keys. The Merkle tree is a fundamental part of blockchain technology, enabling Simplified Payment Verification and protecting against fraud without overwhelming storage or costing a fortune.
The Sloan Digital Sky Survey (SDSS) released Data Release 20 (DR20), marking a milestone in the study of accreting supermassive black holes. DR20 includes over 3.3 million optical spectra, providing unprecedented insights into black hole masses, growth, and physics across cosmic time.
Turning sign language (fingerspelling) into speech w/ smart glasses and a neural net - aadisang/hand-wave
The author shares a list of recommended articles on software development, including topics such as complexity, Separation of Concerns, and accessibility, with the goal of helping programmers create good software. The articles cover various aspects of software development, including React, ORMs, PostGIS, async programming, and design principles, and are intended for programmers of all levels.
Oracle banned AI-generated code from OpenJDK contributions due to safety, security, and intellectual property risks. This policy contrasts with Oracle's internal use of AI models for coding, despite investing $70 billion in datacentre expansion.
A new study suggests that life may have emerged twice, with bacteria and archaea independently developing metabolism and becoming free-living cells. This challenges the traditional view of a single origin of life, with two separate lineages evolving from a primordial soup.
The pgrust query engine is 10x faster than the previous version and outperforms Postgres by 30% on OLTP benchmarks and 300x on Clickbench. Optimizations such as batching, operator fusion, and SIMD enabled pgrust to achieve these performance gains, with the goal of further improving performance through JIT compilation.
Cloudflare has developed a new browser called Kitesurf, designed specifically for AI agents and automation tasks, which is more efficient in CPU and memory consumption than Chromium. Kitesurf is built on top of Cloudflare Workers and uses AI to accelerate the development process, with a focus on scalability, performance, and cost-effectiveness.
The REpsych toolset generates images from a program's control flow graph, translating source images into functioning programs. It works reliably with IDA Pro and semi-reliably with other CFG viewers, creating two programs for each image.
Guarded methods allow attaching constraints to the receiver (self) for certain methods, enabling them to be called only if the receiver satisfies those constraints. In OCaml, guarded methods can be encoded using a type equality witness, specifically the eq type with the Refl constructor, which represents type equalities not known by the type-checker.
