Immersa is a 3D presentation tool that creates animated transitions between slides. It allows users to add 3D models and export presentations as .edn files.
A new study found that over 40% of drivers who died in crashes tested positive for THC, with average blood levels far exceeding impairment thresholds. The rate of THC positivity remained unchanged after recreational cannabis legalization in Ohio.
NIST's Boulder campus lost power due to high winds and utility shutdowns, affecting atomic time scale and internet time services. Standby power generators are failing, causing disruptions to time distribution services.
Codex skills are task-specific capabilities that extend Codex with instructions, resources, and scripts. They can be shared across teams or the community and are built on the open Agent Skills standard.
Grid Lanes is a new CSS feature that allows for flexible masonry layouts on the web, using grid-template-columns and grid-auto-flow to create a layout that works on all screen sizes. It also introduces a new concept called "tolerance" that lets developers adjust how picky the layout algorithm is when deciding where to place items.
I have the somewhat niche problem of trying to fit as many Apple II hi-res images into RAM (and disk) at a time. Uncompressed these images are 8k (well, you can get away with 8184 bytes without any trouble for reasons we'll discuss later). I won't go too much into the wacky world of Apple II hi-res graphics, you can read more on that here. For our purposes the important part is that ...
Researchers now widely accept Chain of Thought (CoT) improves LLM output through internal search and reinforcement learning. CoT may lead to significant AI advancements, potentially reaching AGI without new paradigms, and is a key factor in LLMs' growing capabilities.
User had a busy day at the office, dealing with Westcott and liquidators, and plans to go to Eddie's Cafe and a Chinese dinner. Mistral OCR 3 is a new AI model for extracting text and images from documents with high fidelity, ideal for enterprise pipelines and interactive workflows.
Arduino UNO Q is a Linux-capable board combining real-time control and AI acceleration. It comes with Arduino App Lab, a development environment for coding and integrating sketches, Python scripts, and AI models.
Charles proxy software has released several updates with UI improvements, bug fixes, and new features including dark mode support, TLS debugging, and Brotli compression.
A new £1 billion London Power Tunnels 2 project has started, replacing old cables with a 32.5km tunnel network beneath South London. The first 18km circuit is now live, connecting New Cross and Hurst substations with tunnels up to 50 metres deep.

Raycaster.ai is hiring a Research Engineer to build and ship production systems and define research direction for a document IDE in life sciences. The ideal candidate has strong engineering fundamentals and can learn a domain quickly.
A modern database design for local SSDs should have a cache sized to store pages expected to be accessed in the next 30 seconds for optimal cost and consider transfers to disk not to be much smaller than 32kB on average for optimal throughput. The database should commit transactions to a distributed log for multi-machine multi-AZ durability and use high-quality clocks and knowledge of actual ...
The project provides software that runs over the Internet across multiple datacenters, allowing deployment everywhere. It received funding from the European Union and NLnet for its development.
Researchers at the University of Warsaw have developed a method to detect and calibrate terahertz frequency combs using Rydberg atoms. This breakthrough enables precise measurements in the terahertz range, opening doors to sensitive spectroscopy and quantum sensors.
Airbus is seeking a digitally sovereign European cloud provider for mission-critical workloads with an 80/20 chance of finding a suitable one. The contract, worth over €50 million, aims for long-term price predictability and European control over sensitive information.
Clone tvterm repository with submodules using git clone --recursive. Build tvterm with CMake, enabling -DTVTERM_USE_SYSTEM_LIBVTERM and -DTVTERM_USE_SYSTEM_TVISION options.
In certain conditions, aircraft will leave contrails that linger for hours and turn into artificial cirrus clouds.These clouds act like a blanket on the planet and significantly add to global warming.
Go developers use map[int]bool to track unique values but experienced developers use map[int]struct{} to save memory due to zero-sized type. However, this change had no effect on memory consumption in Go 1.24 due to the new Swiss Tables map implementation.
semistable::vector is a header-only library that provides a thread-safe, contiguous vector with iterator stability. It uses epoch descriptors to track changes and ensure iterator consistency.
NOAA has launched a groundbreaking new suite of operational, artificial intelligence (AI)-driven global weather prediction models, marking a significant advancement in forecast speed, efficiency, and accuracy. The models will provide forecasters with faster delivery of more accurate guidance, while using a fraction of computational reso
User tried Fuzix, a UNIX descendant, on a Raspberry Pi Pico. They successfully compiled and ran it, accessing a UNIX filesystem and common utilities.
The author reverse engineered a TP-Link Tapo C200 camera's firmware using AI and found several security vulnerabilities, including a private key exposure and integer overflows in the HTTPS server and ONVIF service. The vulnerabilities allow for MitM attacks, remote code execution, and enumeration of nearby WiFi networks, which can be used to determine the camera's location.
2025 was a transformative year for LLMs with the emergence of Reinforcement Learning from Verifiable Rewards (RLVR) and the development of new LLM apps and agents. The industry is on the cusp of significant progress with LLMs displaying jagged capabilities, empowering regular people to approach programming, and opening up new possibilities for software development and interaction.
The creator made a video showcasing a unique musical instrument setup with 9 custom instruments, including NES timpani, using a combination of C64 hardware and clever audio processing. The video and audio were recorded simultaneously, with some sections recreated using an automaton for precise sound capture.
