Show HN: Praxos – team messaging with built-in memoryhttps://www.praxos.ai/Hey HN! What does a regular workflow at a startup look like?Probably like this:> One founder talks to customers> Another founder builds> A customer asks for something. The first founder explains it to the second. The second founder explains it to Claude> Two weeks any one of the founders asks one of the following questions: \* Why are we building it this way? \* What happened here? \* What did we promise ACME we’d do? \* How far along are we on X? > Then you scream on the inside because you have to figure out what happened...Before agents, the person who did one part of the work usually held a mental map. They could share the context with other people. Increasingly, they can’t.Small teams can run far more work in parallel than ever before thanks to AI, but someone now has to connect all that context manually. The reasoning behind one product change might now be scattered across a customer call, two emails, a Slack thread, and four Claude conversations.Praxos is a team messaging app.It

Are you good at AI, or just using it?https://news.ycombinator.com/item?id=49378057We’re working on a ladder for individual AI proficiency and would love feedback on both the levels and the definitions.L0 New: brand new to AI, or has not yet used it.L1 Chat: simple prompt-and-response use. Work is serial: ask, wait for an answer, then ask again.L2 Contextual Work: gives AI relevant documents, data, or workspace context so it can work within the actual artifact and produce a more useful result.L3 Orchestrate: coordinates multiple agents or AI roles across independent workstreams, with work that may review, challenge, compare, or build on other work. This is not just for engineering.L4 Automate: creates workflows that are triggered by business events and run without someone sitting at a laptop directing each step.L5 Loop: feeds the output of those workflows back into shared knowledge or a company brain, so future workflows improve over time.A few things I’d love your perspective on:Are these the right levels? Are any of the names unclear or overlapping? What observable

Show HN: WaveHouse – Supabase for ClickHousehttps://wavehouse.devWhile building an IoT telemetry solution, we ran into hurdles with Clickhouse. For one, you can't insert quickly AND durably into Clickhouse without setting up something like Kafka, which gets complicated for quick projects wanting to make use of Clickhouse's powerful features. Then, trying to actually query Clickhouse and show data in a UI required a whole backend API to handle auth and permissions.We figured that all these parts together – fast, durable ingest, row-level and column-level security and roles, and realtime streaming – were a lot of scaffolding to have to rebuild for every project we wanted to use Clickhouse in. So, we built them all into a single Go binary to be deployed alongside Clickhouse, to help lower Clickhouse's barrier to entry. We call it WaveHouse.Would love any feedback as we work on improving and adding more features to this OSS project!

Show HN: AI-Native Accelerator that helps builders make something people wanthttps://foundera.app/Most people are not validating their ideas before start building it! I am a 5th time tech founder, gaming included and I built & managed startup accelerator programs. I know lot of things about early stage founders and their pains as I have been there. That is why I am building Foundera. It’s an AI-Native Accelerator for tech builders. Today the problem is; most of the AI coding tools opens with a chat and asking “type your idea and start building”. This is wrong! I want to reduce the time and money spent on ideas that nobody asked for. Try it at https://foundera.app and give me your feedback so that I can help more people.

Ask HN: How to engage users in an open source project and when to stop?https://news.ycombinator.com/item?id=49377336I have been working on an OS project for years now, on and off, taking it back up for the last few months and giving it a good boost lately with AI. It has a super niche user base in quantitative finance.I really enjoy working on it, and although I get contacted every now and then by people who are using it or are interested in using it, and those are really interesting users, I always think I am wasting my time. It has been 8 years now since I started.I guess my questions are: is it worth it? And I know this question has two clear paths, the personal and the practical one, but I would like to hear from both. How can I know when to stop? If my audience is maybe in the order of two thousand potential users worldwide, how do I validate the idea? I have posted on Reddit and HN multiple times, tried LinkedIn, and that leads me to a handful of super interesting contacts, but I don't know if it is enough to keep going.

Show HN: Epho – run Claude Code with a curlhttps://epho.ioHey folks, Burak here.Epho is an API that allows running Claude Code, Codex or Opencode in a sandbox in the cloud. It abstracts away sandboxes, and allows running coding agents with a single HTTP request.Epho came out of our own struggles with building our own AI analyst: - Sandboxes give you bare machines; you need to configure them for agentic workloads. - Each agent behaves differently, and you need to build integrations with each of them. - Sandbox providers are not very reliable, which means you need to figure out a multi-provider strategy to avoid failures. - Logging, artifacts, input/output, event streaming, and all of the other operational aspects need to be figured out.We had to go through the pain ourselves. We got to a point where things got quite reliable, and it became more obvious to us that this should be a primitive on its own: send a POST request, get the events streaming back to you.Epho is an agents-as-an-API product: you send a request, it spins up a sandbox, config

Algorithm Interview: a conversation between two parrotshttps://news.ycombinator.com/item?id=49373709Algorithm Interview: a conversation between two parrotsAll children know that parrots can talk. All adults understand that parrots simply repeat sounds.You'll laugh, but these same adults actually believe that an Algorithm Interview is a conversation between a very smart algorithm expert who is trying to find out whether the candidate understands algorithms at an acceptable level…So, how many ycombinator.com readers have successfully passed the algorithms interview? Probably tens of thousands.Well, how many of them were able to understand that breaking down sorting into independent stages is a Fundamental Discovery? Zero!Zero questions and comments: https://news.ycombinator.com/item?id=49314420P.S. Have you ever thought that NOT everyone has a mental model? But most people just memorize ready-made answers instead of understanding the problem?I recommend reading The Programmers' Stone https://www.datapacrat.com/Opinion/Reciprocality/r0/index.html ---------------8

Show HN: Protobuf.com, a visual, interactive guide to Protocol Buffershttps://protobuf.com/Protobuf is a fairly simple format, but the way people are first introduced to it often doesn't speak to them. That is how it was for me at first. I tried to address that in two ways: simple visual diagrams where a picture does the work better than prose, and interaction so you can get a feel for the language and how it behaves without installing anything.Some parts of the guide run a real Protobuf compiler, bufbuild/protocompile, in the browser through WASM. It's the same compiler the buf CLI uses.Feedback welcome.Disclosure: I work at Buf, and Buf owns the domain. The guide started as a side project before I joined.
