Immersive video offers a 6-Dof-free viewing experience, potentially playing a key role in future video technology. Recently, 4D Gaussian Splatting has gained attention as an effective approach for immersive video due to its high rendering efficiency and quality, though maintaining quality with manageable storage remains challenging. To address this, we introduce GIFStream, a novel 4D Gaussian representation using a canonical space and a deformation field enhanced with time-dependent feature streams. These feature streams enable complex motion modeling and allow efficient compression by leveraging their motion-awareness and temporal correspondence. Additionally, we incorporate both temporal and spatial compression networks for endto-end compression.
Experimental results show that GIFStream delivers high-quality immersive video at 30 Mbps, with real-time rendering and fast decoding on an RTX 4090.
DB Browser for SQLite (DB4S) is a high quality, visual, open source tool designed for people who want to create, search, and edit SQLite or SQLCipher database files. DB4S gives a familiar spreadsheet-like interface on the database in addition to providing a full SQL query facility. It works with Windows, macOS, and most versions of Linux and Unix. Documentation for the program is on the wiki.
If you’re serious about AI Agents, this is the guide you’ve been waiting for. It’s packed with everything you need to build powerful AI agents. It follows a very hands-on approach that cuts down your time and avoids the common mistakes most developers make.
Andreas Horn on AI Agents vs Agentic AI
1. 𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀: 𝗧𝗼𝗼𝗹𝘀 𝘄𝗶𝘁𝗵 𝗔𝘂𝘁𝗼𝗻𝗼𝗺𝘆, 𝗪𝗶𝘁𝗵𝗶𝗻 𝗟𝗶𝗺𝗶𝘁𝘀 ➜ AI agents are modular, goal-directed systems that operate within clearly defined boundaries. They’re built to: * Use tools (APIs, browsers, databases) * Execute specific, task-oriented workflows * React to prompts or real-time inputs * Plan short sequences and return actionable outputs
But even the most advanced are limited by scope. They don’t initiate. They don’t collaborate. They execute what we ask!
2. 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗔𝗜: 𝗔 𝗦𝘆𝘀𝘁𝗲𝗺 𝗼𝗳 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 ➜ Agentic AI is an architectural leap. It’s not just one smarter agent — it’s multiple specialized agents working together toward shared goals. These systems exhibit: * Multi-agent collaboration * Goal decomposition and role assignment * Inter-agent communication via memory or messaging * Persistent context across time and tasks * Recursive planning and error recovery * Distributed orchestration and adaptive feedback
Agentic AI systems don’t just follow instructions. They coordinate. They adapt. They manage complexity.
Maya blue is a highly unusual pigment because it is a mix of organic indigo and an inorganic clay mineral called palygorskite.
Echoing the color of an azure sky, the indelible pigment was used to accentuate everything from ceramics to human sacrifices in the Late Preclassic period (300 B.C. to A.D. 300).
A team of researchers led by Dean Arnold, an adjunct curator of anthropology at the Field Museum in Chicago, determined that the key to Maya blue was actually a sacred incense called copal. By heating the mixture of indigo, copal and palygorskite over a fire, the Maya produced the unique pigment, he reported at the time.
If you’re serious about protecting your IP, client relationships, and professional credibility, you need to stop treating generative AI tools like consumer-grade apps. This isn’t about fear, it’s about operational discipline. Below are immediate steps you can take to reduce your exposure and stay in control of your creative pipeline.
Use ChatGPT via the API, not the public app, for any sensitive data.
Isolate ComfyUI to a sandboxed VM, Docker container, or offline machine.
Audit every custom node, don’t blindly trust GitHub links or ComfyUI workflows
Educate your team, a single mistake can leak an unreleased game asset, a feature film script, or trade secrets.
The new Vancouver virtual stage will measure 50 feet in diameter, 23 feet tall, and will have a 14 foot deep semi-circle to surround actors and physical sets with a digital environment. There’s also two movable wild walls 20 feet wide and 16.5 feet tall and mounted on a ground-hover system to allow quick repositioning, especially for capturing car driving scenes.
OpenAI researchers fed the following Lord-of-the-Rings-style prompt to the system: Legolas and Gimli advanced on the orcs, raising their weapons with a harrowing war cry.
The computer composed this appropriately violent addition:
The orcs’ response was a deafening onslaught of claws, claws, and claws; even Elrond was forced to retreat. “You are in good hands, dwarf,” said Gimli, who had been among the first to charge at the orcs; it took only two words before their opponents were reduced to a blood-soaked quagmire, and the dwarf took his first kill of the night.”
The company’s decision to keep it from public use is the latest indication of a growing unease in and about the tech community about building cutting-edge technology — in particular AI —without setting limits on how it can be deployed.
Amazon and Microsoft in particular have voiced their support for legislation to regulate how facial recognition technology can and can’t be used. And Amazon investors and employees (as well as a dozens of civil rights groups) have urged the company to stop selling its face-recognition technology, Rekognition, to government agencies due to concerns it could be used to violate people’s rights.
Temporary Use: AI-generated material can be used for ideation, visualization, and exploration—but is currently considered temporary and not part of final deliverables.
Ownership & Rights: All outputs must be carefully reviewed to ensure rights, copyright, and usage are properly cleared before integrating into production.
Transparency: Productions are expected to document and disclose how generative AI is used.
Human Oversight: AI tools are meant to support creative teams, not replace them—final decision-making rests with human creators.
Security & Compliance: Any use of AI tools must align with Netflix’s security protocols and protect confidential production material.
To measure the contrast ratio you will need a light meter. The process starts with you measuring the main source of light, or the key light.
Get a reading from the brightest area on the face of your subject. Then, measure the area lit by the secondary light, or fill light. To make sense of what you have just measured you have to understand that the information you have just gathered is in F-stops, a measure of light. With each additional F-stop, for example going one stop from f/1.4 to f/2.0, you create a doubling of light. The reverse is also true; moving one stop from f/8.0 to f/5.6 results in a halving of the light.
