Cohere has launched Transcribe, an open-weight ASR model with a remarkable 5.42% word error rate. This model offers enterprises state-of-the-art accuracy, comparable to closed APIs, while allowing on-premise deployment to address data residency, control, and latency concerns. Transcribe currently leads the Hugging Face ASR leaderboard, outperforming Whisper and other industry leaders.
This article details the journey of debugging mysterious system freezes caused by eBPF programs in the Linux kernel. We uncovered an issue where an NMI-driven eBPF sampling program would self-deadlock by attempting to acquire a spinlock already held by another eBPF program on the same CPU, leading to 250ms kernel timeouts. The analysis highlights the complexities of spinlocks, NMIs, and cache coherence in kernel development.
