just now (301+ words) Most of us know that Rust can target almost anything - from microcontrollers to desktop apps, servers, and even browser-based applications. But are these practical use cases, or just proofs of concept that we wouldn't apply in practice? I decided to find out. " Let me share my project with you: an on-desk watch combined with a meteo station. " Features: World Time (automatic timezone detection + NTP synchronization) Weather Forecast (two-day forecast for the current location) Current Weather (live data from nearby meteo stations) Fully configurable through an embedded web UI " Implementation (all in Rust!): [system] Embedded: Multi-threaded app built with ESP-IDF, running on ESP32-S3 (Xtensa) Frontend: Two Leptos apps compiled to WASM, client-side rendered Backend: Two serverless functions built with Spin SDK, deployed to Fermyon Cloud Simulator: Built with help of ratatui, runs in the terminal on x86 Scripting: Helper tool using rust-script crate…...

Today, we dive into the core of Spark's execution engine - an essential concept for every Data Engineer who wants to write efficient and scalable ETL pipelines. Let's break down Spark architecture in a way that is simple, visual, and interview-friendly. " Why Learn Spark Architecture? If you understand how Spark works internally, you can: Spark has 3 major components: If the driver crashes " the entire application stops. Executors die when your Spark application ends. If you allocate: 4 executors 4 cores per executor " You get 16 parallel task slots. This system allocates machines to Spark. Standalone - Local clusters YARN - Hadoop ecosystem Kubernetes - Cloud-native Spark Databricks - Managed Spark service Cluster manager = Resource allocator, not responsible for task scheduling. Task scheduling is done by the driver. " Spark Execution Process: Simplified Step 1: You write code Driver receives commands....

Sunlight, water, and air may soon replace fossil-fuel-driven chemistry in producing hydrogen peroxide, one of the world's most essential industrial molecules. Cornell researchers have unveiled a solar-powered method that could transform how this chemical is made, potentially allowing factories, water-treatment plants, and even remote facilities to generate it onsite. The breakthrough centers on two engineered materials that use visible light to convert water and oxygen into hydrogen peroxide, offering a cleaner alternative to the longstanding, waste-intensive anthraquinone process. Published recently by Cornell scientists, the research points to a decentralized future for a chemical used everywhere from paper bleaching and semiconductor fabrication to wound disinfectants and household cleaners. "Currently, hydrogen peroxide is made through the anthraquinone process, which relies on fossil fuels, produces chemical…...

The newspaper reported that Altman sent an internal memo to staff Monday saying more work was needed to enhance the artificial intelligence chatbot's speed, reliability and personalization features. This week marks three years since OpenAI first released ChatGPT, sparking global fascination and a commercial boom in generative AI technology and giving the San Francisco-based startup an early lead. But the company faces increased competition with rivals, including Google, which last month unleashed Gemini 3, the latest version of its own AI assistant. OpenAI didn't immediately respond to a…...

17+ min ago (496+ words) Most people assume AI nutrition advice works like magic: ask a question, get an answer. But anyone who has spent real time with large language models knows the truth'AI is only as good as the structure of the data behind it and the clarity of the prompt in front of it. No general-purpose LLM can intuit this structure. It must be modeled, encoded, and reasoned over with intention. A generic prompt like "Give me a healthy dinner" produces a generic response. Even "healthy dinner for my body type" fails unless the system has been fine-tuned on Ayurvedic physiology and its intricate rule sets. Most users don't know how to prompt for: the qualities (gunas) that aggravate their imbalance the impact of stress, sleep quality, or digestion type So if the user doesn't know what to ask, the AI cannot deliver…...
