AI News
#1 - How AI is unlocking ancient texts — and could rewrite history
AI technology is revolutionizing how researchers study ancient texts, with breakthrough achievements like reading the previously unreadable Herculaneum scrolls (ancient Roman texts charred by Mount Vesuvius in 79 AD) and translating vast archives of Korean royal records. Using various neural network models, researchers can now decipher damaged texts, fill in missing characters, translate rare languages, and even read sealed documents through CT scans, potentially unleashing a flood of new historical information that could transform our understanding of the ancient world.
#2 - From engines to algorithms: Gen AI in automotive software development
McKinsey reports that automotive companies are heavily investing in generative AI to transform their software development processes, with potential time savings of up to 40% for developers. While gen AI offers significant productivity gains, successful implementation requires careful consideration of safety-critical systems, proper training, and the right operating model to be effective in automotive applications.
#3 - AI Bot Wows The Crowds With Unprecedented Stock Earnings

#6 - Publishing On Google Play Is Officially A Nightmare
According to this article by Andrew Zuo, Google Play's app publishing process has become increasingly problematic compared to Apple's App Store, with longer approval times, inconsistent rejections, and vague feedback about policy violations. The piece highlights how several developers, including iA Writer and Syncthing, have faced significant challenges with Google Play's requirements and permission systems, while Apple's review process has actually improved in speed and clarity – a complete reversal from years past when Google Play was considered the more developer-friendly platform.
#7- Mojo App Boosts Revenue by 60% Through Strategic Pricing and Paywall Optimization
Mobile video editing app Mojo achieved a remarkable 60% increase in Average Revenue Per User (ARPU) over five months through three key changes: making yearly subscriptions the default option, optimizing regional pricing strategies, and reframing annual costs as monthly payments. The improvements were accomplished with minimal engineering resources using tools like Superwall, Amplitude, and RevenueCat, while maintaining the app's high 4.9/5 rating and strong product fundamentals.
#8 - What Every Developer Should Know About Offline-First Apps
The article provides a comprehensive guide to building offline-first applications, emphasizing the importance of treating offline functionality as the default rather than an error state.
