A writer replaced their laptop with a Morefine M6 mini PC and Nreal Air AR glasses for a week, aiming for ultimate portability and a large virtual workspace. While the setup provided a surprisingly functional experience for coding, writing, and web browsing with a simulated triple-monitor array, it wasn't without drawbacks. The glasses, while comfortable, lacked proper dimming and offered limited peripheral vision. The mini PC required external power and peripherals, impacting the overall portability. Though not a perfect replacement, the experiment highlighted the potential of this technology for a lighter, more versatile computing future.
A US federal judge invalidated a key patent held by Omni MedSci related to non-invasive blood glucose monitoring. This ruling potentially clears a significant obstacle for companies like Apple, who are reportedly developing similar technology for devices like the Apple Watch. The invalidated patent covered a method of using light to measure glucose levels, a technique believed to be central to Apple's rumored efforts. This decision could accelerate the development and release of non-invasive blood glucose monitoring technology for consumer wearables.
Hacker News commenters discuss the implications of the patent invalidation, with some skeptical about Apple's ability to deliver a reliable non-invasive blood glucose monitor soon. Several point out that regulatory hurdles remain a significant challenge, regardless of patent issues. Others note that the invalidation doesn't automatically clear the way for Apple, as other patents and technical challenges still exist. Some express hope for the technology's potential to improve diabetes management, while others highlight the difficulties of accurate non-invasive glucose monitoring. A few commenters also discuss the specifics of the patent and the legal reasoning behind its invalidation.
Motivated by the lack of a suitable smartwatch solution for managing his son's Type 1 diabetes, a father embarked on building a custom smartwatch from scratch. Using off-the-shelf hardware components like a PineTime smartwatch and a Nightscout-compatible continuous glucose monitor (CGM), he developed software to display real-time blood glucose data directly on the watch face. This DIY project aimed to provide a discreet and readily accessible way for his son to monitor his blood sugar levels, addressing concerns like bulky existing solutions and social stigma associated with medical devices. The resulting smartwatch displays glucose levels, trend arrows, and alerts for high or low readings, offering a more user-friendly and age-appropriate interface than traditional diabetes management tools.
Hacker News commenters largely praised the author's dedication and ingenuity in creating a smartwatch for his son with Type 1 diabetes. Several expressed admiration for his willingness to dive into hardware and software development to address a specific need. Some discussed the challenges of closed-loop systems and the potential benefits and risks of DIY medical devices. A few commenters with diabetes shared their personal experiences and offered suggestions for improvement, such as incorporating existing open-source projects or considering different hardware platforms. Others raised concerns about the regulatory hurdles and safety implications of using a homemade device for managing a serious medical condition. There was also some discussion about the potential for commercializing the project.
Karl Guttag analyzes the newly announced "Halliday" AR glasses, skeptical of their claimed capabilities. He argues that the demonstrated "AI features" like real-time language translation and object recognition are likely pre-programmed demos, not actual artificial intelligence. Guttag points to the lack of specific technical details, reliance on pre-recorded videos, and improbable battery life as evidence. He concludes that the Halliday glasses, while potentially impressive AR technology, are almost certainly overselling their AI integration and are more likely sophisticated augmented reality, not AI-powered, glasses.
HN commenters discuss the practicality and potential invasiveness of the Halliday glasses. Several express skepticism about the claimed battery life, especially given the purported onboard processing power. Others question the usefulness of constant AR overlays and raise privacy concerns related to facial recognition and data collection. Some suggest alternative approaches, like bone conduction audio and smaller, simpler displays for notifications. The closed-source nature of the project also draws criticism, with some arguing it limits community development and fosters distrust. Finally, the high price point is mentioned as a significant barrier to entry.

Hacker News commenters were generally skeptical of the practicality and comfort of the author's setup. Several pointed out that using AR glasses for extended periods is currently uncomfortable and that the advertised battery life of such devices is often inflated. Others questioned the true portability of the setup given the need for external batteries, keyboards, and mice. Some suggested a tablet or lightweight laptop would be a more ergonomic and practical solution. The overall sentiment was that while the idea is intriguing, the technology isn't quite there yet for a comfortable and productive mobile computing experience. A few users shared their own experiences with similar setups, reinforcing the challenges with current AR glasses and the limitations of relying on public Wi-Fi.
The Hacker News post "I ditched my laptop for a pocketable mini PC and a pair of AR glasses" generated a moderate amount of discussion, with a number of commenters sharing their own experiences and perspectives on the practicality and future of this type of setup.
Several commenters expressed skepticism about the current state of AR glasses for productivity. They pointed out issues like limited field of view, poor image quality, discomfort during extended use, and social awkwardness in public settings. Some suggested that current AR glasses are better suited for specific niche applications rather than general-purpose computing.
One commenter questioned the author's choice of using a separate mini PC, arguing that a modern phone could likely handle the computational workload and simplify the setup. They also highlighted the potential for future phones to directly integrate AR capabilities, further streamlining the experience.
Another commenter emphasized the importance of input methods, suggesting that a comfortable and efficient input solution is crucial for replacing a laptop. They discussed the limitations of current AR interfaces and expressed hope for future advancements in this area.
A few commenters shared their own experiences with similar setups, using tablets, portable monitors, and Bluetooth keyboards to create mobile workstations. They discussed the trade-offs involved in portability versus functionality and offered insights into the challenges and benefits of ditching a traditional laptop.
Some comments focused on the potential future of AR and mobile computing, envisioning a future where powerful pocket-sized devices combined with advanced AR glasses could replace traditional laptops for many users. However, they acknowledged that significant technological advancements are still needed to realize this vision.
Overall, the comments reflected a mixture of excitement about the potential of AR and mobile computing, tempered by realism about the current limitations of the technology. While some commenters were intrigued by the author's experiment, most agreed that a truly laptop-replacing AR experience is still some way off.
