Ask HN: Is Opus 4.5 scaring the crap out of you as well?
I use Clause Code and Windsurf, in parallel.
Especially in the latter, the promise of "vibe coding" appears to actually be on the horizon.
I don't mean to shill, maybe all other tools are taking advantage of Opus 4.5 as well, but crap... it follows tool calls, it understands context, it has a very recent cutoff date... ummm...
I can now one-shot, or two-shot, somewhat significant features. Am I nuts, or is this like a Sonnet 3.5 level step change?

Show HN: ElfReview – Face detection meets corporate satire for Christmas
I built a satirical "North Pole HR department" that generates bureaucratic performance reviews based on facial expressions.
How it works:
- Upload a photo: the app detects expression locally in browser
- Expression (happy/sad/neutral) determines "naughty or nice" baseline
- Generates a mock HR report with randomized corporate satire (job titles, misconduct logs, gift eligibility scores)

Show HN: Quantum4J–deterministic quantum SDK with OpenQASM and JVM integration
Hi HN,
I have been working on an open source quantum computing SDK for the JVM called Quantum4J. I just launched the official site and wanted to share it here for feedback:
Website: https://quantum4j.com GitHub: https://github.com/quantum4j/quantum4j
What it is: A minimal quantum SDK written in Java Deterministic statevector simulator Strict OpenQASM 2.0 importer/exporter Pluggable backend design (example: IonQ REST API) JVM-first design so Java developers can build quantum workflows using familiar tooling
Why I built it Most quantum libraries are Python-centric and research-oriented; I wanted something that fits normal software engineering practices (builds, tests, CI/CD, Spring, etc).
Features Deterministic simulation (useful for testing + CI) QASM-based circuit interchange Clear, minimal API Real hardware backend example (IonQ) Examples included (Teleportation, Bell state, Grover, etc.)
Docs Full Javadoc published under /javadoc Examples included in the repo
Open to feedback
This started as a side project but it’s now getting more structure (examples, docs, hardware connector). I would love feedback from anyone doing quantum software, JVM work, hardware integration, or QASM tooling.
Thanks! Happy to answer questions.

WebCraft: A C++ 23 async based networking library (which does not use Boost)
I've created a networking library in C++ which works on Linux, Windows, & MacOS and made the core of it based on C++ coroutines and native asyncio from each of these platforms. Check it out: https://github.com/adityarao2005/WebCraft. Unfortunately, the only examples of it in use are in the test cases but I plan on adding examples soon.
Show HN: Mocksy – a lightweight macOS app to mock API endpoints locally
I’m a solo macOS developer and I built Mocksy, a small native app for quickly mocking API endpoints on your Mac. I made it because I often needed simple mock responses while building macOS and iOS apps, but existing tools felt too heavy, required config files, or didn’t integrate smoothly into a local Apple-dev workflow.
Mocksy lets you spin up local HTTP endpoints in seconds, return custom JSON responses without running a backend, test UI states offline, and prototype features without dealing with servers. The goal is to keep it minimal, fast, and unobtrusive.
