Tell HN: PayPal Blocks GrapheneOS

It seems like the PayPal app now refuses to run on GrapheneOS. I don't know if it's only because I have enabled the PayPal card for contacless NFC payments, but when opening the app it crashes with the following exception: com.paypal.oslo.app.rasp.RootDetectionSecurityException: Security policy violation: s=root Comments URL: https://news.ycombinator.com/item?id=49462253 Points: 66 # Comments: 26

MyZubster Is Entering Its Hardest Phase: Connecting Code to Reality

MyZubster Is Entering Its Hardest Phase: Connecting Code to Reality Building a prototype is relatively easy. Building a repository is harder. Building an ecosystem where software, infrastructure, AI, blockchain, contributors and real-world data must work together is something else entirely. That's the phase MyZubster is beginning to enter. MyZubster is an Italian open-source digital ecosystem currently under development. It isn't a finished product, and we don't want to describ...

Ptero now supports API – Free AI Chat with Multiple Models

I've been building a free, open-source AI chat platform called Ptero, and I'm excited to share a new feature: API support! πŸš€ Ptero gives you instant access to multiple powerful language models in one place – no signup required, completely free, and privacy-first. What makes it useful for developers: Debug code, generate boilerplate, brainstorm ideas, and compare responses across models like DeepSeek V4, Llama 3.3, Qwen, MiniMax, and Mistral. One-click model switching to find the b...

I Built a French AI Voiceover API That Only Accepts Payment From Robots

Nobody signed up for my API. Nobody generated an API key. Nobody clicked "Subscribe." And that's by design β€” because the only customers I actually want are AI agents with a wallet and a job to do. Let me back up. The problem: selling API access to AI agents is broken If you've ever tried to monetize a small API, you know the funnel: landing page β†’ sign up β†’ verify email β†’ generate API key β†’ add a credit card β†’ hit a rate limit β†’ maybe, eventually, get paid a few cents per call...

NorthCinder Adds Buyer Approval to MCP Shopping Workflows

NorthCinder is an open-source MCP server intended to let an AI app compare products from sources selected by the buyer, show supporting facts, and obtain approval before a purchase. For developers building agentic-commerce flows, its practical distinction is that recommendation and checkout are deliberately separate: a checkout requires fresh approval for one exact offer and one unit. The project repository says the software is MIT-licensed and self-hosted rather than operated as a NorthCinder...

Migrating from TypeScript/Node.js to Rust? Here's how to map your npm packages

Rewriting heavy TypeScript/Node.js services in Rust is one of the most effective ways to lower your cloud infrastructure bill and eliminate CPU bottlenecks. Whether you're porting an Express/Fastify API to Axum, moving a background worker from Node to Rust, or writing high-performance CLI tools, Rust delivers predictable low latency and negligible memory usage. However, once you set up your Cargo.toml , you face the ecosystem gap . npm has over 2 million packages, while Crates.io has a d...

MVCC Explained: Build Postgres-Style Snapshots in 100 Lines of TypeScript

Open two psql sessions. Session A: BEGIN ; DELETE FROM users ; -- deletes all 1 million rows -- don't commit yet Session B: SELECT count ( * ) FROM users ; -- count: 1000000 Session A deleted every row. Session B sees every row. Neither session is waiting on the other. No locks, no blocking, no errors. So... where are the rows? Deleted, or not? The answer is both , and by the end of this post you'll have built the m...

Qwen3 Embedding on Cloud TPU: Production Long-Context Retrieval with vLLM

Article Summary Google Cloud published native vLLM TPU support for embedding inference on August 26, 2026, targeting production retrieval rather than chat generation. The engineering work focuses on Qwen3-Embedding-8B and Qwen3-VL-Embedding-8B with long text and multimodal contexts, including 16K-class text sequences and 15K+ multimodal inputs. Google addressed TPU tensor alignment, lazy loading, JAX/XLA compilation warm-up, chunked prefill, and pooling-state preservation through a hybrid St...

Vector Search Is Still the Memory Layer Agents Actually Need

When I was working on Vector Search with JavaScript , vector search was a hot topic. By the time the book was published some people had begun saying that because of LLMs and their advances, we have moved beyond vector search. This couldn't be farther from the truth. LLMs and agentic development is amazing, but it often gets things wrong. They don't fail because the model is weak always, but they fail because the right context can be sitting somewhere else and they had no idea that it exis...

I Have No Idea What to Learn First And Here's How I'm Deciding

So I've decided I want to learn web development. Cool. Great. Except then I actually sat down to start and realized... I don't even know what to start with. HTML? CSS? JavaScript? Python? React? Back-end stuff? People keep saying different things and every video has a different "you should start with THIS" opinion. It's honestly kind of overwhelming for someone who hasn't written a single line of real code yet. So instead of learning anything, what I actually did was open like 15 tabs, wat...
