How Slack Rebuilt Notifications 📣
Introduction 🔔 At Slack, notifications are how teams stay in the loop, but they can also become overwhelming when not designed with intention. Our goal was to make staying informed feel effortless. We set out to rebuild one of Slack’s most complicated systems from the ground up by bringing calm, consistency, and clarity to the…

Launch HN: Voltair (YC W26) – Drone and charging network for power utilities
Hey HN! We’re Hayden, Ronan, Avi, and Warren of Voltair ( https://voltairlabs.com/ ). We’re making weatherized, hybrid-fixed drones deployed for power utility inspections. Here’s some footage: https://vimeo.com/1173862237/ac28095cc6?share=copy&fl=sv&fe=... and a photo of our latest prototype: https://imgur.com/a/bYHnqZ4 . The U.S. has 7M miles of power lines (enough to go to the moon and back 14 times), and they're aging. Over 50% of all power flows through transformers that are at least 30 year
Launch HN: Canary (YC W26) – AI QA that understands your code
Hey HN! We're Aakash and Viswesh, and we're building Canary ( https://www.runcanary.ai ). We build AI agents that read your codebase, figure out what a pull request actually changed, and generate and execute tests for every affected user workflow. Aakash and I previously built AI coding tools at Windsurf, Cognition, and Google. AI tools were making every team faster at shipping, but nobody was testing real user behavior before merge. PRs got bigger, reviews still happened in file diffs, and chan

Lesson Three: Rhythmic Productivity—A More Humane Way to Work
Registration for my new course, Everyday Energy opens next week. In anticipation, I’ve written an essay series covering the central philosophy of the course. If you’re just joining us, check out the first essay on why we’re living through a human energy crisis, and an essay on the biological roots of our exhaustion, which we […] The post Lesson Three: Rhythmic Productivity—A More Humane Way to Work appeared first on Scott H Young .

From firefighting to building: How AI agents restored our team’s core productivity
Abstract Grab’s Analytics Data Warehouse (ADW) team supports over 1,000 users each month. These users support an extensive repository of more than 15,000 tables, which powers approximately 50% of all queries within our data lake. However, the manual process of addressing “quick questions” is time-consuming and labor-intensive, thus creating a bottleneck in our operations. The team was drowning in repetitive re

Community is a product decision
I’ve learned over the years that shipping fast compounds exponentially only if you’re also learning fast. Otherwise, you’re just pushing volume (and many mistakes) into production, celebrating the wrong kind of momentum.
Your Startup Is Probably Dead On Arrival
Your Startup Is Probably Dead On Arrival If you started a company more than two years ago, it’s likely that many of your assumptions are no longer true. You need to stop coding, building, recruiting, fund raising, etc., and take stock of what changed around you. Or your company will die. I just had coffee […]

Anime vs. Marvel/DC: Designing Digital Products With Emotion In Flow
Design is about pacing and feelings as much as pixels and patterns. Alan Cohen explores Emotion in Flow and Emotion in Conflict, showing how anime like Dan Da Dan and superhero films like James Gunn’s Superman manage emotional shifts and translating those ideas into practical patterns for product design.

Launch HN: Chamber (YC W26) – An AI Teammate for GPU Infrastructure
Hey HN, we're Jie Shen, Charles, Andreas, and Shaocheng. We built Chamber ( https://usechamber.io ), an AI agent that manages GPU infrastructure for you. You talk to it wherever your team already works and it handles things like provisioning clusters, diagnosing failed jobs, managing workloads. Demo: https://www.youtube.com/watch?v=xdqh2C_hif4 We all worked on GPU infrastructure at Amazon. Between us we've spent years on this problem — monitoring GPU fleets, debugging failures at scale, building
Launch HN: Voygr (YC W26) – A better maps API for agents and AI apps
Hi HN, we’re Yarik and Vlad from VOYGR ( https://voygr.tech/ ), working on better real-world place intelligence for app developers and agents. Here’s a demo: https://www.youtube.com/watch?v=cNIpcWIE0n4 . Google Maps can tell you a restaurant is "4.2 stars, open till 10." Their API can't tell you the chef left last month, wait times doubled, and locals moved on. Maps APIs today just give you a fixed snapshot. We're building an infinite, queryable place profile that combines accurate place data wi
How agentic AI helps heal the systems we can’t replace
By learning the idiosyncrasies of accumulated layers of legacy systems, AI agents can preserve institutional knowledge and provide a unified interface to a range of services.

Launch HN: Spine Swarm (YC S23) – AI agents that collaborate on a visual canvas
Hey HN! We're Ashwin and Akshay from Spine AI ( https://www.getspine.ai ). Spine Swarm is a multi-agent system that works on an infinite visual canvas to complete complex non-coding projects: competitive analysis, financial modeling, SEO audits, pitch decks, interactive prototypes, and more. Here's a video of it in action: https://www.youtube.com/watch?v=R_2-ggpZz0Q . We've been friends for over 13 years. We took our first ML course together at NTU, in a part of campus called North Spine, which
Moving From Moment.js To The JS Temporal API
The way JavaScript handles time has evolved significantly, from the built-in `Date` API to Moment.js and now Temporal. The new standard fills gaps in the original `Date` API while addressing limitations found in Moment and other libraries. Joe Attardi shares practical “recipes” for migrating Moment-based code to the new Temporal API.

Launch HN: IonRouter (YC W26) – High-throughput, low-cost inference
Hey HN — I’m Veer and my cofounder is Suryaa. We're building Cumulus Labs (YC W26), and we're releasing our latest product IonRouter ( https://ionrouter.io/ ), an inference API for open-source and fine tuned models. You swap in our base URL, keep your existing OpenAI client code, and get access to any model (open source or finetuned to you) running on our own inference engine. The problem we kept running into: every inference provider is either fast-but-expensive (Together, Fireworks — you pay f
