By Madhu Unnikrishnan

Members of our SFMTA bike-commute panel: From left, Julia Friedlander, Michael Rhodes and Jack Anninos (not pictured: Elliot Goodrich, Christy Osorio and Miriam Sorell). Between our typically mild weather and expansive bicycle network, San Francisco is pretty much ideal for bike commuting. And indeed, the city has among the highest percentage of bike commuters in the U.S. We’ve done a lot of work to make San Francisco more bike friendly. We have a 400-mile bike network that includes more than 130 miles of dedicated bike lanes, 87 miles of off-street paths and 51 miles of bike lanes that are...

Keeping Muni Metro Safe and Running: Fix-It Week Recap

Keeping Muni Metro Safe and Running: Fix-It Week Recap
By Sevilla Mann

Fix-It Week is when we take extra time to do big maintenance projects that keep Muni Metro running smoothly. This helps prevent problems before they happen, so your trips are faster, trains arrive on time and the subway stays clean and safe. Most of our maintenance work happens overnight, after the last train of the day. But sometimes that’s not enough time to get bigger jobs done. During Fix-It Week, the Market Street Subway is closed early each night at 9:30 p.m. to give crews more time to repair, replace, clean and inspect important equipment between Embarcadero and West Portal. From May 5...

Show HN: I built an AI tool that generates click-worthy YouTube thumbnails Hey HN! Software engineer here. As an amateur youtuber, I've been struggling with thumbnails, especially since I don't have any design or editing skills. Decided to give it a try and make my own automatic thumbnail generator. Me being an ADHD person, made sure that there's no parameter tuning and shape choosing and fuss like that, just simply give prompt and generate thumbnail. Increased my CTR from 1.2% to 2.3% (faceless fantasy books niche on youtube) Thumbnail X (completely free for now) - https://thumbnailx.com/ Just wanna add that this is by no means a perfect thumbnail maker for huge YouTube moguls with millions of subscribers but I'm sure it's gonna be extremely helpful for beginner youtubers and medium size channels struggling with thumbnails. Tools used: 1. Cursor for development (shoutout to claude oppus 4.0) 2. Few image generators (primarily ideogram, but leonardo ai, deep ai and gpt 4o as fallbacks) 3. Few llms (chatgpt, claude, gemini for validating images and prompt enhancement) 4. AWS and Redis for storage & caching 5. Digital ocean for hosting and db 6. Python https://thumbnailx.com/ May 29, 2025 at 02:51AM

Show HN: Octogen: e-commerce capabilities for agents https://ift.tt/AqPgYvX

Show HN: Octogen: e-commerce capabilities for agents Hi HN, We just released a public beta of e-commerce capabilities for AI agents — aimed at developers building shopping agents or personal assistants. It’s early and buggy, but we’d love your feedback. Try a live demo here: https://ift.tt/BP0zZAp --- ## Why we built this We believe the biggest *technical* bottleneck in building consumer e-commerce agents is fragmented product data and inconsistent schemas across online stores. So we created a high-fidelity yet unified interface for *e-commerce catalog + checkout*, regardless of the underlying platform. --- ## What it does We currently offer two core capabilities: ### 1. Unified product catalog (for LLM-style search) - Octogen automatically wrangles any ecommerce site into a common schema — a superset of `schema.org/Product`. - It works across platforms and is available today for hundreds of sites. - You can request new stores — ~95% are processed fully autonomously. - Useful for agents doing RAG-based product search with rich attribute awareness. ### 2. Agentic checkout (closed beta) - Works on *any ecommerce site* using virtual cards (Visa only for now). - Enables agents to complete checkout flows much faster than browser-based "computer agents." - We're working on support for additional vaults/wallets/payment APIs. --- If you’re working on agentic commerce, autonomous checkout, or personal AI shoppers — we’d love your feedback and ideas.
