Show HN: Running the second public ODoH relay https://ift.tt/XYtsqQT

Show HN: Running the second public ODoH relay Every privacy-focused DNS service requires an account: NextDNS, Cloudflare for Families, Apple's iCloud Private Relay (paid, iOS-only). The protocol that doesn’t require one - ODoH - had basically one well-known public relay operator (Frank Denis on Fastly Compute, default in dnscrypt-proxy). I built a second one and the client to talk to it. https://ift.tt/yhuMgd1 May 14, 2026 at 12:44AM

Show HN: HYPD – AI co-pilot for marketers running Google Ads https://ift.tt/XiDQrbA

Show HN: HYPD – AI co-pilot for marketers running Google Ads We've been building HYPD for the last 1 year together with a small team in Berlin. It's an AI co-pilot (chatbot) for PPC freelancers and agencies. It connects to a Google Ads account, then runs audits, performs data analysis from natural language ("why did CAC jump last Tuesday"), generates ad copy grounded in account history and context, and exports reports and datasets. Thesis behind it: just like programming is "solved" but engineering is not, ad-ops and media buying will be solved, but account strategy and human creativity remain the leverage. Background: I founded PubNative (acquired by Verve Group), was Co-CEO at Verve Group, and for the last year we've been "taming" LLMs when working with structured and unstructured data. So far we got more than 200+ agencies and freelancers onboarded. Hard parts so far: (1) data accuracy, (2) understanding the gaps in LLM knowledge of the Google Ads API, (3) adding enough context to make answers fit what professional marketers expect. Free trial + free tier on the site. Happy to enable demo accounts for anyone who wants to test it without connecting their account. https://www.hypd.ai/ May 12, 2026 at 11:09PM

Show HN: Java/Spring Boot Idempotency Library https://ift.tt/J4Hk5jM

Show HN: Java/Spring Boot Idempotency Library Idempotency4j is a Java idempotency library with pluggable storage backends and Spring Web / Spring Boot support. This library solves the problem of ensuring that sensitive endpoints do not trigger side-effects multiple times - this is especially useful for any endpoints that handle financial operations. Currently, the library supports Spring MVC (Servlet-based) applications and MySQL and PostgreSQL with jdbc regarding storage backends. It is very simple to integrate, all that you have to do is add @Idempotent to any endpoints that need idempotency. Full explanation of the functionalities and configuration is available in the readme of the repository. Repository : https://ift.tt/1I56pQj I would love any feedback or review regarding the implementation - also, any recommendation is welcome. https://ift.tt/1I56pQj May 11, 2026 at 10:23PM
