ONNX Runtime and CoreML May Silently Convert Your Model to FP16

Published: 2025-12-22 | Origin: Hacker News

Yusuf Mohammad discusses the implications of running an ONNX model with ONNX Runtime (ORT) using the CoreMLExecutionProvider, which can affect model predictions due to default behavior that casts models to FP16. To ensure the model remains in FP32 on a Mac GPU, a specific setup for the InferenceSession is recommended. After training the EyesOff model, evaluations showed discrepancies in outputs when comparing model performance between ONNX on MPS, ONNX on CPU, and PyTorch on both platforms

A guide to local coding models

Published: 2025-12-21 | Origin: Hacker News

The article initially discussed the viability of local coding models, suggesting they could potentially replace higher-cost coding subscription services. However, after community feedback, the author acknowledged a mistake in their hypothesis, correcting it from a tentative endorsement to a clear recommendation against dropping existing coding subscriptions for local models. The author emphasizes that while local models can perform approximately 90% of software development tasks, the final 10%—crucial for professional environments—is where these models fall short. They clarify that their perspective was

Crunch: A Message Definition and Serialization Protocol for Getting Things Right

Published: 2025-12-21 | Origin: /r/programming

Crunch is a C++ message definition and serialization framework designed for mission-critical and resource-constrained systems. It emphasizes the importance of message semantics alongside structure and includes features such as built-in field and message validation. Crunch is header-only, requires C++23, and does not use STL libraries for dynamic memory allocation. Users can integrate it by copying the include directory into their project and configuring their build system accordingly. Validation occurs during the serialization and deserialization processes, but it can be bypassed if needed.

A Fair, Cancelable Semaphore in Go

Published: 2025-12-21 | Origin: /r/programming

The author invites technically inclined readers to attempt building a semaphore from scratch in their preferred programming language, sharing their own challenging experience with Go, which was more difficult than expected due to concurrency and locking bugs. Semaphores are used in programming to manage access to shared resources and limit concurrent task execution. The author illustrates a problem that can arise from not using semaphores when exceeding file descriptor limits in an operating system. In Go, channels facilitate communication between goroutines but lack a first-in-first-out (
