Same Java, Just Safer: A Practical Null-Safety Solution
What it does
Stop NullPointerExceptions in your Java projects without a full rewrite. JADEx is a practical safety layer that brings modern null-safety and readonly semantics to existing Java code Key Features: - Non-null by default: Catch bugs at compile-time, not in production - Readonly Enforcement: Optional final-by-default for safer state management Perfect for teams with legacy code who want Kotlin-style safety while staying 100% in the Java ecosystem.

Hey there HN! I just wrapped up an all-day documentation spree for Instant API, a JavaScript framework for easily building web APIs that implements type safety at the HTTP interface. It uses a function-as-a-service approach combined with a slightly modified JSDoc spec to automatically enforce parameter and schema validation before HTTP requests make it through to your code.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
