AI Architect Trainer is an independent, free training platform for engineers and architects who build systems around large language models, rather than only prompting them. Every lesson, question and flashcard exists in both Ukrainian and English. There is no paid tier. The platform a model runs inside, across four layers: the data fabric and distributed compute beneath it, lakehouse storage and incremental views, the semantic ontology and domain model that give data meaning, entity resolution and knowledge graphs, attribute-based access control and policy enforcement, provenance and lineage for compliance, decision intelligence, and consensus between reasoning agents. Each lesson names the…from exam.advocacy.uno

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
