"In music theory, a clef is a symbol placed at the beginning of a musical staff that assigns specific pitch names to the lines and spaces. A decision model is analogous to a music clef because it helps define the domain of the context and the subsequent notes (actions) that follow it."

"The solution to these problems is simple: don't key on the ANN address. That is precisely the change turbopuffer v3 makes."

"We very roughly estimated some time ago that developing a full port to iOS would take one man-year of work. So, the scope of this remains very large."

"Building a web engine by hand costs hundreds of engineers and many years, so only a few companies can have one, and only they decide how the web works."

We build serverless applications on AWS for clients and for our own SaaS products. On client projects, we work directly with their developers and help them understand and maintain what we build. You’ll write backend code in TypeScript/Node.js, build APIs with Lambda and API Gateway, model data in DynamoDB, and design event-driven workflows and integrations. Infrastructure lives in code using AWS CDK, with CI/CD pipelines for builds and deployments. You’ll help decide how systems are designed and take testing, observability and security into account as you build. There’s some React/Next.js work too. We’re looking for practical experience building AWS serverless applications with TypeScript/Node.js, including infrastructure as code, CI/CD and event-driven design. The role includes working through requirements and technical decisions with clients, so you should be comfortable with that. We use coding agents daily and expect you to use them too, and to share useful approaches with other developers. AWS serverless development is the main focus of the role. We’re remote-first, use Scrum, and work with code reviews, pair programming, and unit and integration tests. We meet in person regularly, sometimes in Cologne, sometimes in Austria or Mallorca.

"Shepherd (Series B) | ONSITE | San Francisco, CA & New York City, NY. At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered. The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that. We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building. We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too! We’re hiring for 2 Senior Full Stack Software Engineers, 1 Machine Learning Engineer and 1 AI Product Manager in SF, and 2 Staff Full Stack Software Engineers in NYC. Engineers own projects end-to-end so full stack ability is expected. Check out our open roles here: https://shepherdinsurance.com/careers Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis – If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you. * In the form, be sure to mention that you heard about this opportunity via Hacker News.

"Floating-point math requires rounding, so it’s not perfectly accurate. But how inaccurate it is depends on how you do your computation: two ways of writing the same mathematical formula can have radically different accuracy."

"Matching frontier model performance was a huge milestone for our routing model, and in my opinion validates our initial hypothesis that an ensemble of models can do better than any single model ever could."

"We first built K2 because we needed a durable buffer on the edge, initially to serve as the ingestion layer for Basin Pipelines."

"The team also says phase-coherent transmissions would be possible, but they aren't implementing them right now because they could be misused."

"I'm a full-stack marketer and developer. For about 15 years, I've worked where customer insight, growth strategy, and implementation meet. Companies usually bring me in when the product is good but growth is blocked. Positioning may be unclear, the funnel may be leaking, attribution may be broken, or niche's where there's no existing playbooks. I go through the customer data, sales calls, support messages, product usage, and analytics. Then I find the real problem and build what is needed: the positioning, landing pages, tracking, automations, content, or first growth test."

"Some things I've done: - Grew a professional-services company from zero to 210k monthly organic visits and 20 to 222 qualified leads a month. - Interviewed 20+ potential customers for an AI company, found two use cases, and helped get two enterprise design partners before launch. - Built SEO, analytics, tracking, landing pages, and acquisition systems for SaaS, ecommerce, and service companies. - Managed performance marketing across Southeast Asia with budgets up to $2.5m a month."

"Creative technologist / product engineer. Two sides: AI tooling and automation for teams, and generative/immersive art. Same instinct either way - prototype fast, make the abstract real."

"Recent work: - Idea Engine (open source): start from a seed word, wander an association map, and pin the path you took into a buildable concept card. Three-model pipeline - one proposes associations, one scores and filters them for surprise and coherence, one writes the card. Svelte + Hono + SQLite, runs locally in Docker. https://github.com/somaticbits/idea-engine - Forward-deployed engineer at a large hospitality/marketplace company. Built automations that removed up to 6h of manual work per project. - Slides and websites generated straight from existing Figma components. Design system in, finished artifact out. - Currently writing a custom MCP server for a calisthenics training app, so workouts and progress are coached and queried by an agent rather than through the UI."

"Senior backend engineer focused on distributed systems and system design, with about a decade of end-to-end ownership across design, implementation, and production. Most recently, I was lead backend engineer and architect on a distributed platform for venture capital workflows (Go services, event-driven architecture on GCP, data reconciliation, observability), and lead engineer on a survey fulfilment system integrating various third-party providers. Both roles included mentoring and coordinating other engineers. I'm looking for a permanent role, but remain available for contract work in the meantime."

"We introduce Context Language Models (CLMs), language models that natively manage their own context."

"The mean wall-time reduction was 4.57%, which is a remarkable improvement in just two months. Of the 629 benchmark measurements, 555 of them improved and only 74 regressed."

"In my garden you find polyhedron models made of paper: Platonic polyhedra, Archimedean polyhedra and other polyhedron models."

"We're using our most advanced technology to improve the systems that power AI. With Synopsys, we're bringing that work to chip design, helping engineers explore more designs and get to a working chip faster."

"This explains the otherwise confusing result where SPF and DKIM both say “pass,” but DMARC says “fail.” The checks can succeed for the wrong domains."

"TIN is fast (at least 8x faster than ParadeDB 0.25 in every PlanetScale benchmark). So fast that the only response which made sense was to shut up and put on our performance optimization hats."

"Agents controlling visual interfaces directly (or via MCP into browser orchestrators) bypass all traditional API-based authorization controls. Protecting the open web from lockdown will require robust authentication of web bots or web agents."

"The exactness is in the specification, not in the hardware."

"The "Red Hat" brand (and badge) is being dissolved some more today."

"Even with additional industry DRAM clean room space plans with robust demand trends, including new upside requests from customers, we do not have line of sight to when supply and demand will return to balance."

"That AFU state is captured. Even if that device does reboot for any number of reasons, memory maintenance or the power is lost or whatever, the AFU state is not lost. This is the true magic behind the GrayKey Preserve and the Evidence Preservation Mode function."

"I think in spirit, when I created MCP, I envisioned an open ecosystem. That to me feels core. Seeing restrictions like this is sad and I hope Figma can get to a point where it's more open or at least make the process of getting into the allowlist very easy."

"A collection of minimal, generative and customizable SVG-patterns."

"You are trying to get a million dollars. The million dollars is stored in his balls."

"In an early demonstration of its impact, the model uncovered a critical vulnerability exposing sensitive personal information across healthcare software used by hospitals worldwide, identifying a severe risk that previous frontier models had missed."
