DARPA is exploring the potential of growing large-scale biological structures (500+ meters) in microgravity, leveraging recent advances in metabolic engineering and biological self-assembly. The initiative aims to revolutionize space infrastructure by enabling the biological manufacturing of structures like space elevator tethers, orbital debris nets, and space station components.
A creative DIY project demonstrates how to transform old LCD TVs and projectors into high-quality displays by using the projector as a dynamic backlight. The modification achieves OLED-like black levels and contrast by removing the projector's color wheel and applying specialized image processing, resulting in performance that rivals modern displays at a fraction of the cost.
TSMC announced plans to invest over $100 billion in expanding its U.S. chip manufacturing operations, including three new chip plants, two packaging facilities, and an R&D center in Arizona. The significant expansion was announced jointly by TSMC CEO C.C. Wei and President Trump at the White House.
Scaling systems or projects by a factor of 100 requires complete rethinking of approaches and methodologies, illustrated through examples like bridge construction. Each order of magnitude increase presents unique challenges, but adding two zeros fundamentally disrupts all aspects of the problem domain and demands entirely new solutions.
Jet engine development represents one of engineering's toughest challenges, requiring extraordinary performance at low cost while operating near technological limits. Modern engines must achieve high efficiency, reliability, and safety across diverse conditions, with development costs reaching billions and taking decades to yield returns. The complexity and precision required in both design and manufacturing means only a handful of companies worldwide can successfully produce commercial jet engines.
NVIDIA's RIVA 128 (NV3) was their first commercially successful GPU in 1997, featuring DirectX 5 support and competing with 3dfx's Voodoo Graphics. The architecture introduced key innovations in graphics processing while marking NVIDIA's shift from proprietary APIs to standard ones like Direct3D, ultimately helping launch the company's success in the GPU market.
TigerBeetle rebuilt their documentation site from scratch, moving away from Docusaurus to achieve better performance, simplicity, and integration with their zero-dependency philosophy. The new implementation uses Zig and Pandoc, resulting in a 10x reduction in footprint while maintaining functionality and adding features like integrated search and offline capabilities.
A Y Combinator-backed startup, Optifye.ai, has developed an AI surveillance system that monitors factory workers' movements and productivity through computer vision. The system, created by Duke University students from manufacturing families, allows supervisors to track worker efficiency in real-time and confront underperforming employees directly. The technology raises concerns about worker privacy and workplace conditions, similar to existing surveillance systems in remote work and Amazon warehouses.
A personal account details the development of the XB-70 Valkyrie supersonic bomber through the lens of a father's career at General Electric during the Cold War. The ambitious aircraft project, despite its technological advances, was ultimately reduced from a strategic bomber program to a research vehicle due to the rise of ballistic missiles. The narrative weaves together family history, technological innovation, and Cold War politics while following the father's professional evolution from farm boy to engineer.
David E. Weisberg chronicles the 80-year evolution of Computer-Aided Design (CAD) through extensive interviews with industry pioneers and detailed company histories. The comprehensive 650-page document covers CAD's development from its 1950s origins through the early 2000s, offering insights into the technology, companies, and individuals who revolutionized engineering design.
