• Hacker News1Qwen3-Coder: Agentic coding in the worldQwen3-Coder, a new code model with 480B parameters, offers exceptional performance in coding and agentic tasks. It supports long context lengths and comes with tools like Qwen Code CLI and Claude Code integration. The model excels in coding while preserving general abilities and aims to improve software engineering tasks.Hardware requirements:Discussion of hardware needed to run Qwen3, with focus on RAM (128-500GB) and GPU (24GB VRAM) requirements. Various quantization options (2-8 bit) affect hardware needs. Mac Studio with 512GB RAM mentioned as viable option.Model comparison:Debate about keeping up with rapid LLM developments vs waiting for market maturity. Some advocate tracking all new models, others suggest waiting for clear winners. Discussion of whether consolidation will occur or if rapid change will continue.Development workflow:Analysis of how coding agents fit into developer workflows, noting only 5% of time spent coding. Discussion of whether AI can help with non-coding tasks like documentation, meetings, approvals that consume most developer time.
• Reddit science1Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
