Ask HN: What makes you keep coming back to Hacker News?
I've been active on GitHub and tried sharing my work on Twitter, but it often felt like shouting into the void. Memes get likes — but meaningful tools often don’t reach anyone.Then I rediscovered Hacker News. Even with a new account and a small project, the feedback was real. People cared, engaged, and it felt like being heard — not scrolled past.I realized that HN is more than a dev forum. It’s like a daily newspaper of thoughts and discoveries. Some users share research, others ask life q

We Tried Helping Medical AI Startups Get Diverse Data. Here's What We Learned
I’m a medical doctor and founder of a small startup called Craniolabs. A month ago, my cofounders and I started working on a painfully obvious problem in medical AI: the lack of diverse, high-quality, ethically sourced medical imaging data, especially from underrepresented regions like Africa, Asia, and the Middle East.Everyone in the field talks about bias in datasets, but very few seem to be solving it at the root. So we tried.We signed memorandums of understanding with hospitals in Egypt and
Upwork Suspended My Account Without Reason
A few months ago, I joined Upwork, spending weeks learning how the platform works and carefully building my profile with a strong portfolio and clear description so it would represent me well to clients. I thought Upwork would be a great place to land small projects, earn some side income and start my freelancing journey.In May, I started actively applying for jobs and quickly landed my first project with an Italian client who wanted an Android kiosk app for restaurants in Italy. The client was
Show HN: Castream – Mobile multi-streaming app (Android live, iOS in beta)
Hi HN – I built [Castream](https://castream.io), a native mobile app for multi-streaming live video to platforms like YouTube, Facebook, Twitch, and more — directly from your phone.Android is available now on the Play Store, and iOS is currently in beta.I built this because I was frustrated with having to rely on OBS setups and clunky desktop workflows just to stream to multiple destinations. Castream lets you go live in seconds, with native camera + mic capture, high-quality video, an
Ask HN: How are Kafka or event-driven systems used in LLM infrastructure?
Curious how some event-driven technologies like Kafka (or alternatives) fit into the backend and/or infrastructure of large LLM providers.Some of the questions I have in mind are more:1. How do large LLM providers handle the flow of training data, evaluation results and human feedback? Are these managed through event streams (like Kafka) for real-time processing or do they rely more on batch processing and traditional ETL pipelines?2. For complex ML pipelines with deps (eg. data ingestion -

Ask HN: How are you productively using Claude code?
I tend to be sceptical when it comes to LLM based coding tools but many people seem to be raving about huge productivity gains which I wouldn’t mind as well.However when trying cc it left me vey disappointed. For context I’m working on a relatively greenfield rust project and gave it tasks that I would consider appropriate for a junior level colleague like:- change the return type of a trait and all it’s impls- refactor duplicate code into a helper function- replace some of our code with an exte
