META'S NEW SUPERINTELLIGENCE LAB IS DISCUSSING MAJOR A.I. STRATEGY CHANGES

A small group of members in Meta's newly formed superintelligence lab last week discussed the possibility of abandoning the company's most powerful open source AI model, Behemoth, in favor of developing a closed model. Meta has chosen to open source its AI models for years, with executives arguing that it is better for the technology to be public to accelerate AI development and make the technology more accessible to developers. A move to a closed AI model would be a philosophical change as much as a technical one. Meta has been delaying the release of its Behemoth model due to its poor internal performance.

PARSING 1 BILLION ROWS IN BUN/TYPESCRIPT UNDER 10 SECONDS

A dev tackled the 1 Billion Row Challenge in Bun/TypeScript, processing a 13.8GB file containing temperature data for weather stations in under 10 seconds. They bypassed initial memory limitations by using file descriptors with 128KB buffer chunks (optimized for kernel readahead pages) instead of loading the entire file into memory, and they used worker threads to parallelize both I/O and CPU-intensive operations across multiple cores. They also aggregated min/max/average values using hash maps while using Bun's performance advantages over traditional Node.js.

Google plans to combine Android with ChromeOS. Chromebooks can already run many Android apps, and Android has been moving closer to ChromeOS with new features like desktop mode, resizable windows, and improved support for external displays. Bringing the two operating systems together makes sense as it will speed up feature development and improve functionality on tablets.

COVID-19 VACCINE TECHNOLOGY ADAPTED TO DEVELOP FIRST MRNA DEFENSE AGAINST ANTIBIOTIC-RESISTANT BACTERIA

Israeli researchers have created an mRNA-based vaccine against Yersinia pestis, the bacterium that causes bubonic plague. The researchers hope the technology can be used to combat other lethal bacteria as well. When tested on animal models, the vaccine achieved 100% protection against pneumonic plague. The success of the study paves the way for a whole world of mRNA-based vaccines against other deadly bacteria.

DARPA SETS NEW RECORD FOR WIRELESS POWER BEAMING

The United States' Defense Advanced Research Projects Agency (DARPA) recently transferred over 800 watts of power over about 30 seconds with a laser beam across 8.6 kilometers. The estimated power efficiency was around 20%. The team used commercial ready-to-use solar cells placed within a receiver to turn the laser beam into electricity. Laser technologies are more suitable than infrared for building an airborne power relay network due to their high precision, long-range reach, and lighter and smaller equipment required to work.

AWS PREVIEWS KIRO IDE FOR DEVELOPERS WHO ARE OVER VIBE CODING

AWS has introduced a new agentic IDE called Kiro that apparently avoids the pitfalls of vibe coding. It is built around a conversational interface that offers developers the chance to explain what they are trying to build. Kiro then uses generative AI to produce its response, which initially takes the form of a spec, not actual code. Kiro can handle multiple specs created by different teams that all work on different aspects of a project. It can use plugins written for VS Code and Open VSX.
