The author developed the multiplayer drawing game Drawize for a Samsung Tizen OS app contest in late 2016, completing it in just 4 weeks, including a real-time multiplayer engine, but didn't win an award. After releasing it online in early 2017, the project gradually grew. Now, 8 years later, the database has processed 100 million drawings. Technically, the backend uses .NET and WebSockets for real-time synchronization, the frontend is handwritten HTML/JS, data is stored in PostgreSQL and MongoDB, and Wasabi cloud storage is used to save costs. The author uses an AI content classification model trained in 2021 to filter inappropriate content. On busy days, there are 30,000 active users with approximately 3.16TB of storage. The 100 millionth drawing was a red balloon. This story shows the transformation from a failed project to a successful product, highlighting the indie developer's efforts in scaling a real-time multiplayer game, handling reconnection edge cases, and content moderation. The author is open to discussing technical details, such as how .NET handles the load and the application of AI in content safety.

Lustra is an open-source project created by Jacek, designed to solve the problem where 95% of legislation is overlooked due to unreadable original texts. The platform utilizes Google's Vertex AI (Gemini 2.5 Flash) to process bills, removing political bias and ranking content through user voting (a 'shadow parliament'). Its tech stack includes a Flutter frontend, with Firebase and Google Cloud Run powering the backend. Users can submit citizen bill drafts, which are then scored and validated by AI. The project has launched versions for the United States and Poland, with plans to expand to the EU, UK, France, and Germany. The open-source license permits non-commercial use, and contributors are welcome to help develop data adapters for other parliaments. The current goal is to enhance the database with existing funding.

Author Yascha Mounk critically analyzes the methodological flaws in the World Happiness Report, pointing out that its reliance on a single question (the Cantril Ladder) to assess national happiness fails to truly measure emotional states. Research reveals that Nordic countries rank high in the report, yet actually suffer from high rates of mental health issues such as suicide. Economists Blanchflower and Bryson conducted alternative research using multi-dimensional indicators (such as positive and negative affect), overturning the original rankings: Finland dropped to 51st place, while several U.S. states (like Hawaii) ranked among the world's happiest regions. The article exposes how media and institutions have spread "elite misinformation" without adequate scrutiny, calling for greater emphasis on reliability and critical thinking in data science.

This article, written by veteran graphics programmer Sebastian Aaltonen, delves deep into the historical evolution and future direction of graphics APIs. Based on 30 years of industry experience, the author argues that modern APIs like DirectX, Vulkan, and Metal are outdated. Their designs are based on GPU architectures from a decade ago, leading to complexity and performance issues such as PSO permutation explosion. The article proposes innovative simplification solutions: adopting CUDA-like memory management, 64-bit pointers, unified descriptor heaps, and leveraging modern GPU's unified memory access and bindless resource features. This would significantly reduce API complexity, improve efficiency, and bring revolutionary changes to fields like gaming, AI, and autonomous driving. The author emphasizes that this simplification will usher in a new era for graphics programming, easing the burden on developers and fully unlocking hardware potential.

This article focuses on the best RAG (Retrieval-Augmented Generation) systems for local deployment on Windows, with Ollama support. Users with limited GPU memory but strong privacy concerns want to deploy efficient RAG solutions on their own computers. The author tested MaxKB, Openwebui, and Cherry Studio with embedding models like gte-qwen2-7b-instruct and Qwen3-Embedding-4B, but achieved mediocre results. The article invites the community to share comparative experiences to help users optimize their local AI deployments. This offers practical value for readers interested in local LLM applications, privacy protection, and cutting-edge technology evolution, especially those exploring AI solutions in resource-constrained environments.
