Comcast has quietly made some changes to its Xfinity Mobile plans, including revised data policies for all customers on unlimited plans and the removal of by-the-Gig packages for new customers. Comcast said it has removed the “data threshold” it had applied to its primary Unlimited plan, essentially matching what it offers to customers on the Premium Unlimited plan launched about a year ago. Previously, customers on the Unlimited plan would see their speeds reduced after they consumed 30 Gigabytes or more of mobile data in a given month.Comcast confirmed that the change took effect on April 8 and that the Xfinity…

Modern conversational AI agents can typically handle complex, multi-turn tasks like asking clarifying questions and proactively assisting users. However, they frequently struggle with long interactions, often forgetting constraints or generating irrelevant responses. Improving these systems requires continuous training and feedback, but relying on the “gold standard” of live human testing is prohibitively expensive, time-consuming, and notoriously difficult to scale.As a scalable alternative, the AI research community has increasingly turned to user simulators — LLM-powered agents explicitly instructed to roleplay as human users. However, modern LLM-based simulators can still suffer from a significant realism gap, exhibiting atypical levels of patience or…

Enterprise data is rarely useful in a silo. Answering questions like, “Which of our products have had declining sales over the past three months, and what potentially related issues are brought up in customer reviews on various seller sites?” requires reasoning across a mix of structured and unstructured data sources, including data lakes, review data, and product information management systems. In this blog, we demonstrate how Databricks Agent Bricks Supervisor Agent (SA) can help with these complex, realistic tasks through multi-step reasoning grounded in a hybrid of structured and unstructured data. Figure 1: Comparison between the quality of SoTA baseline…

Once models are downloaded, there’s no programmatic interface to how they’re managed — at least, not yet. On Google Chrome there’s a local URL, chrome://on-device-internals/, that shows which models have been loaded and provides statistics about them. You can use this page to remove models manually or inspect their stats for the sake of debugging, but the JavaScript APIs don’t expose any such functionality. When you start the inference process, there may be a noticeable delay between the time the summarization starts and the appearance of the first token. Right now there’s no way for the API to give us…

Image: Generated via Google’s Nano Banana Adobe rushed an emergency patch for a critical flaw under active attack. Discovered by security researcher and EXPMON founder Haifei Li, the high-severity vulnerability has been exploited in the wild since at least December 2025, according to multiple reports. It has been assigned a CVSS score of 8.6 out of 10 and tracked as CVE-2026-34621. The exploit carries such gravitas that Adobe had to release an emergency patch for all affected products and urged users to update them immediately, as no workaround is available. How malicious PDFs bypassed Adobe’s sandbox Bugs in software may…

Mercury released into the oceans affects marine environments worldwide. Traditionally, its distribution and quantity have been estimated using marine biogeochemical simulation models. A recent international study led by Japanese researchers analyzed blood mercury concentrations in more than 11,215 seabirds from 108 species, of which 659 were newly collected samples and over 10,556 were from previous studies. This is the first biologically based estimate of oceanic mercury distribution, say the researchers. The study found that mercury levels in seabirds vary according to prey trophic level, bird body weight, and foraging depth. The findings were published in Science and the Total Environment.…

Researchers have pushed mercury telluride nanocrystal photodiodes past a key performance limit by combining an ultrathin cadmium sulfide shell with revised cadmium-based interface chemistry, according to a study published in Advanced Materials. Study: Surface Passivation of HgTe Nanocrystals Enabling E G /2Open-Circuit Voltage and Their Coupling to Dielectric Cavity for Narrow Detection. Image Credit: KPixMining/Shutterstock.com The approach raises open-circuit voltage above half the optical bandgap and supports narrowband infrared detection in a dielectric cavity. Saving this for later? Download a PDF here. Colloidal HgTe nanocrystals have been widely studied for infrared optoelectronics because their bandgap can be tuned across a broad…

Key Takeaways: Vibe coding is fast but fragile Production systems require structure and discipline The gap between the two is where most failures happen AI is a powerful tool, but not a complete solution The proliferation of artificial intelligence has had a profound impact on software development. Today, an application can be built in a weekend. Sometimes, even in a few hours. With modern AI coding tools, a single prompt can generate entire features, APIs, and user interfaces. This new way of building software is called vibe coding, a term popularized by AI researcher Andrej Karpathy in early 2025. Founders…
