Networks are everywhere. They connect computers across the internet, carry electricity through power grids and represent transport routes for moving people and goods. Yet many problems that appear to have nothing to do with networks can also be represented and solved as networks. Examples include matching passengers with drivers in a ride-hailing app or distributing computing tasks across servers. https://techxplore.com/news/2026-09-randomness-vast-network-problems.html Software Fri, 11 Sep 2026 11:40:03 EDT news708345421 New research suggests that generative artificial intelligence (AI) could weaken not only employment opportunities for junior software developers but also the pathway through which they develop into senior professionals. https://techxplore.com/news/2026-09-ai-junior-coding-tasks-weaken.html Software Thu, 10 Sep 2026 13:40:01 EDT news708263881 AI systems that generate video frame by frame could follow a user's camera commands far more accurately, thanks to a new training method developed by researchers from the University of Surrey and NVIDIA. This improvement matters most when someone steers a generated scene rather than simply watching it. That includes video games built on AI-generated worlds, virtual production sets where a director can move a camera around, and simulated environments used to train robots. The findings are posted on the arXiv preprint server. https://techxplore.com/news/2026-09-ai-generated-scenes-properly-user.html Computer Sciences Thu, 10 Sep 2026 10:20:11 EDT news708254161 A guiding principle for many software engineers—"What you see is what you get" —means creating programs where the content you're editing looks the same as the final product. But when you're using generative AI (genAI) systems to 3D-print, say, a mug, you'll likely get a cup that can't hold your coffee. Why is that? https://techxplore.com/news/2026-09-software-tool-users-ai-generated.html Software Wed, 09 Sep 2026 15:20:04 EDT news708185941 When a website loads quickly or an operating system runs smoothly, you can thank caching—a widely used computing process for fast data access that works by storing frequently used pieces of data in a computer's memory. https://techxplore.com/news/2026-09-year-strategy-ai-era-centers.html Software Wed, 09 Sep 2026 14:40:09 EDT news708183421 Quantum error correction must detect and correct errors without directly reading the quantum information. Classical low-density parity check (LDPC) codes have a well-established design theory: by choosing how many checks connect to each bit, retaining appropriate randomness, and avoiding short loops, designers can pursue both a large minimum distance and a threshold phenomenon in which the decoding failure rate drops sharply below a predicted noise level. https://techxplore.com/news/2026-09-classical-ldpc-code-theory-quantum.html Computer Sciences Wed, 09 Sep 2026 09:20:04 EDT news708163863 The results are in: Which AI model is the most fallible?
