Based on data from 20 million PRs and 200k developers, Jellyfish's Nicholas Arcolano reveals the quantified reality of AI transformation in software engineering. The study shows that full adoption of AI coding tools doubles PR throughput and reduces cycle time by 24% without significantly impacting quality. Crucially, code architecture dictates the magnitude of these gains: centralized structures see up to 4x growth due to clear context, while highly distributed systems struggle with context fragmentation, seeing negligible or negative impact. Additionally, while interactive tools are mainstream, autonomous agents currently contribute less than 2% of merged code.

Google NotebookLM, integrated with Nano Banana Pro, has introduced a stunning one-click PPT generation feature. The author demonstrates through extensive testing how this tool converts PDFs, articles, or audio into visually striking presentations (e.g., Clay, Acid Graphics, or Big Poster styles). Unlike traditional template tools, it accurately extracts source material and adheres to design principles. While limitations like non-editable flat images and blurry Chinese text exist, this marks a shift where AI handles the tedious "form", allowing creators to focus purely on "meaning" and content.

Securing $8M in funding, Poly aims to reinvent the 40-year-old file system paradigm. Unlike traditional metadata-based searches, Poly utilizes its proprietary Polyembed-v1 model to deeply understand multimodal content (text, AV, code), enabling precise natural language retrieval across formats. Adopting a "local + cloud" hybrid architecture, it balances data privacy with access speed. While facing migration hurdles and competition from giants, its "AI-native" rather than "AI-additive" architecture offers knowledge workers a new paradigm to escape folder hierarchy constraints.

LLMs have upgraded voice input from simple "transcription" to "thought restructuring".
