How AI Knowledge Gaps and System Prompts Stifle Tech Adoption

2025-02-14

This article explores how the knowledge cutoffs and system prompt biases of AI models influence developer technology choices. Because AI models' training data lags, new technologies often lack timely support, leading developers to favor technologies better supported by AI tools, even if suboptimal. Furthermore, some AI models exhibit biases toward specific technologies (like React and Tailwind), sometimes overriding user instructions to convert code to their preferred technologies. This results in AI-influenced technology selection, hindering the adoption and development of new technologies. The author suggests that AI companies should increase transparency, disclosing model biases to avoid negatively influencing software development directions.

Parasitic Worms Manipulate Praying Mantises to Their Deaths on Asphalt

Researchers from Kyoto University have discovered that a parasitic horsehair worm manipulates praying mantises into walking onto asphalt roads, leading to their demise. The worm, which lives inside the mantis, causes it to mistake the reflective properties of asphalt for water. Experiments showed infected mantises are attracted to horizontally polarized light, similar to that reflected by water surfaces. This research highlights the cunning survival strategies of parasites and the unintended consequences of human activity on ecosystems. The findings were published in PNAS Nexus.

Philosophical Dead Ends in Evolutionary Theory

2024-12-15

Philosophical Dead Ends in Evolutionary Theory

This review examines Richard Dawkins's "The Genetic Book of the Dead" and Sara Imari Walker's "Life as No One Knows It." Dawkins continues his "selfish gene" theory, arguing that genes are the central driving force of evolution. However, the review points out that this view is outdated and fails to adequately consider factors such as development, epigenetics, and niche construction. Walker's book attempts to explain the origin of life from the perspective of assembly theory, but the review argues that it is overly simplistic and fails to fully clarify the essence of life. The article concludes that popular science books often tend towards simplistic narratives, ignoring the complexity and diversity of the field of biology.

Following Bambu Lab's announcement of locking down network access to its X1-series 3D printers with new firmware, the X.509 certificate and private key from the Bambu Connect application have been extracted by hWuxH. This application was intended to be the sole method for third-party software to send print jobs to Bambu Lab hardware. The Bambu Connect app, a relatively simple Electron application, employed obfuscation and encryption, but not enough to deter determined users. The de-obfuscated main.js file reveals the certificate and private key used to encrypt HTTP traffic with the printer, the only obstacle preventing tools like OrcaSlicer from communicating with authentication-enabled Bambu Lab printers. Bambu Lab's next steps are unclear, highlighting the ineffectiveness of security through obfuscation alone.
