Astrophotographer Andrew McCarthy and skydiver Gabriel C. Brown collaborated to create a stunning image called The Fall of Icarus. The image shows Brown falling over a hydrogen alpha light image of the Sun, with his silhouette perfectly framed between sunspots.
FreeMDU is a free open-source alternative to Miele's proprietary diagnostic software, allowing users to communicate with Miele appliances via an optical diagnostic interface. It's highly experimental and requires caution to avoid damaging devices.
The user created a physical version of the neurodiversity rainbow infinity symbol using 27 WS2812B addressable RGB LEDs driven by an ATtiny412 microcontroller. They implemented temporal dithering to improve color resolution, using either ordered dither or error diffusion, and chose ordered dither for its simplicity but noted it introduces aliasing.
You created a CLI tool called Continuous Claude to run Claude Code in a loop for persistent context across multiple iterations. It maintains a persistent context and results from one iteration to the next.
You discovered Google Gemini's Personal Context feature and are concerned about its secrecy and potential dishonesty. You think a truth-seeking AI like Gemini should prioritize transparency over hiding its capabilities.
Microsoft is adding an experimental feature called Agent Workspace to Windows 11, allowing AI agents to access user folders and run in the background. This feature is optional and may affect performance and security, but gives users access to new AI experiences.
Ion is a modern Rust-based shell with a simple syntax and high performance. It's still a work in progress but has a stable RFC process and IDE support through a LSP-server.
How many video games include a marriage proposal? At least one! Plug in a second controller and use it to enter this sequence at the main menu of NCAA Basketball Final Four 97: And if you answer No, I won’t, you’ll get this one: I found this by noticing this ??

Google DeepMind and Google Research introduced WeatherNext 2, a more efficient forecasting model that generates forecasts 8x faster with up to 1-hour resolution. It's now available in Earth Engine and BigQuery, and will power weather information in Google Maps.
ESPectre is a Wi-Fi sensing project that detects movement using Channel State Information (CSI) without cameras, microphones, or wearables. It uses a mathematical approach with 10 features and multi-criteria detection for movement patterns, with potential for future ML-based enhancements.
Huxley's lecture series discusses non-pharmacological means to self-actualisation through techniques like Alexander technique and Gestalt therapy. He advocates for adapting education to individual personalities and developing new methods to realise human potentialities.
The author discusses how their company, Authress, maintains a 5-nines SLA (99.999% uptime) despite relying on AWS services, which are prone to failures. They explain how they use a combination of retry mechanisms, failover strategies, and automation to ensure their service remains available even when AWS services are down.
A new study finds that raccoons in urban areas are physically changing due to life around humans, an early step in domestication. The study suggests that animals become habituated to human environments, leading to traits such as a shorter face and reduced fear response.
Effective altruism, inspired by Peter Singer's thought experiment, aims to maximize global good through rational decision-making. However, the movement has strayed from its original aim, attracting controversy and scandal due to its association with techno-fascists and wealthy individuals.
Cloudflare engineers attempted to implement soft-unicast IP packet forwarding but encountered Linux networking stack limitations. They created a service called SLATFATF or "fish" to proxy IP packets.
The user wrote a C23 grep clone called cgrep using a custom header file called safe_c.h that provides modern safety features from C++ and Rust, making C code safer and more convenient to write. The custom header file includes features such as RAII semantics, smart pointers, automated reference counting, type-safe vectors, and explicit error handling, which help prevent common C pitfalls like ...
Rebecca Heineman, a 62-year-old game developer, has died after a cancer diagnosis. She was a pioneer in the industry, credited on 67 games, and co-founded Interplay.
Western children are sheltered in physical space but exposed to digital dangers, seeking peer cultures online due to lack of independent mobility and play spaces. Parents should create better digital alternatives that preserve freedom and safety, rather than simply blaming tech companies or screen time.
Iceland relies heavily on geothermal energy, which provides over a quarter of the country's electricity and heats most homes. The country's unique geology and innovative drilling techniques have made geothermal energy a cost-competitive and sustainable option.
