The day after the Supreme Court struck down a set of Donald Trump’s emergency tariffs, the president quickly imposed another, using a never-before-invoked provision of a decades-old trade law to order a global 10 percent tariff on most imports. Now, that second set of tariffs has been deemed illegal, and there are no more emergency levers that Trump can pull to try to replace them any time soon. That leaves Trump without much negotiation leverage a week before […]

My teammates and I built a simple RL agent (actor-critic with ppo) that can paint from text prompts. The reward function is based on the CLIP similarity between the canvas and the text prompt. I just wanted to share the results and listen to your feedback. The prompt of the above painting is: “A painting of a red apple with a small leaf”. submitted by /u/Now200 [link] [comments]

RingCentral has expanded its AI Receptionist product with new links to Shopify, Calendly and WhatsApp, as the communications software company tries to push the product beyond basic call answering and into more routine customer service tasks. The company said AI Receptionist, known as AIR, can now handle some order enquiries through Shopify, arrange appointments through Calendly, and respond to inbound WhatsApp messages. AIR is also being added to shared SMS inboxes and call queues, so it can answer […]

Raising a capable AI agent on a limited local compute budget kaibot — an AI agent running locally on constrained hardware Two years ago I made a deliberate choice to go small on local compute. I swapped out my workstation for a $300 Windows mini PC — AMD Ryzen 5, 8GB RAM (about 5GB actually usable by the time the OS takes its cut), no discrete GPU. The philosophy was simple: everything compute-intensive lives in the cloud. LLMs run on Claude, OpenAI, Gemini, OpenRouter. […]

Curvature is conceptually simple but usually difficult to calculate. For a level set curve f(x, y) = c, such as in the previous couple posts, the equation for curvature is Even when f has a fairly simple expression, the expression for κ can be complicated. If we define then the level set of f(x, y) = c is an equilateral triangle when c = −4. The level sets are smoothed triangles for −4 < c < 0. The curvature of these level sets […]

Open ChatGPT and ask it to book you a flight. It will write you a beautifully formatted itinerary, suggest some airlines, and tell you to head over to Expedia. Now imagine asking the same thing and watching the assistant actually open a browser, search across three sites, compare prices, check your calendar for conflicts, hold the cheapest option, and email you for confirmation before paying. That second thing is an agent. The first thing is a chatbot. This series is about […]

Seismic data analysis is an essential component of energy exploration, but configuring complex processing workflows has traditionally been a time-consuming and error-prone challenge. Halliburton’s Seismic Engine, a cloud-native application for seismic data processing, is a powerful tool that previously required manual configuration of approximately 100 specialized tools to create workflows. This process was not only time-consuming but also required deep expertise, potentially limiting the accessibility and efficiency of the software. To address this challenge, Halliburton partnered with the […]

Modern AI-generated video systems are often discussed as though they emerged from a single breakthrough model. In practice, they resemble distributed software systems far more than singular inventions. The realism people associate with synthetic avatars, AI presenters, or deepfakes is not the result of one network suddenly “learning video.” It comes from the orchesation of multiple specialized systems operating across different representations of information: text embeddings, latent image spaces, phoneme timings, motion constraints, temporal attention layers, and post-processing […]
