Augurs is a demo showcasing a decentralized prediction market platform built on the Solana blockchain. It allows users to create and participate in prediction markets on various topics, using play money. The platform demonstrates features like creating binary (yes/no) markets, buying and selling shares representing outcomes, and visualizing probability distributions based on market activity. It aims to highlight the potential of decentralized prediction markets for aggregating information and forecasting future events in a transparent and trustless manner.
Skies-ADSB 2.0 is a web application that visualizes real-time aircraft positions in 3D using data from ADS-B receivers.

HN users discussed Augurs' demo, with several expressing skepticism about the claimed accuracy and generalizability of the model. Some questioned the choice of examples, suggesting they were cherry-picked and lacked complexity. Others pointed out potential biases in the training data and the inherent difficulty of accurately predicting geopolitical events. The lack of transparency regarding the model's inner workings and the limited scope of the demo also drew criticism. Some commenters expressed interest in the potential of such a system but emphasized the need for more rigorous evaluation and open-sourcing to build trust. A few users offered alternative approaches to geopolitical forecasting, including prediction markets and leveraging existing expert analysis.
The Hacker News post titled "Augurs demo" linking to https://demo.augu.rs/ generated a moderate discussion with several interesting points.
One commenter expresses skepticism about the practical applicability of the demo, stating that while it's a cool demonstration of technology, they haven't encountered any real-world problems where this type of augmented reality interface would be superior to existing solutions. They question the value proposition of the technology beyond its novelty factor.
Another commenter focuses on the user interface and user experience aspects. They raise concerns about the potential for "UI hell" with augmented reality applications, pointing out the challenges of managing and interacting with numerous virtual elements overlaid on the real world. They suggest that this type of interface could quickly become overwhelming and difficult to use effectively.
A different user picks up on this UI/UX thread and compares the demo to previous attempts at AR interfaces. They draw a parallel to Google Glass and suggest that the demo suffers from similar issues of clunkiness and a lack of clear use cases. This commenter believes that the core interaction paradigm needs significant improvement before such technology becomes truly useful.
Some commenters discuss the specific technical implementation of the demo. One user questions the choice of using WebXR, suggesting that native development might offer better performance and a smoother experience. Another delves into the technical challenges of object recognition and tracking, pointing out the difficulty of accurately placing virtual objects in the real world and maintaining their position as the user moves.
One commenter offers a more positive perspective, suggesting that the demo could be useful for specific niche applications, such as providing real-time information to maintenance technicians or assisting with complex assembly tasks. They acknowledge the current limitations but see potential for future development.
Finally, a few commenters express general excitement about the potential of augmented reality and see the demo as a promising step in the right direction. They believe that as the technology matures and the interface improves, augmented reality could have a significant impact on how we interact with the world around us.
Overall, the comments reflect a mixture of excitement, skepticism, and pragmatic concern about the current state and future potential of augmented reality technology as demonstrated by the Augurs demo. Many commenters acknowledge the technical achievements while questioning the practicality and usability of the current implementation. The discussion revolves around key themes of user experience, technical implementation, and real-world applications.
