Users with Ryzen 7040, 8040 and Ryzen AI 300/400-series chips can glean utilisation, power and performance metrics for their onboard neural accelerators. A reassuring way to tell if an AI workload is actually using the NPU rather than quietly frying your CPU. You might cock an eyebrow at hearing โ€œPowerPCโ€ mentioned.

b4 0.16.0 released

Konstantin Ryabitsev has announced the release of version 0.16.0 of the b4 software-development tool. The biggest change is the addition of bug-tracking support: The new "b4 bugs" command integrates with git-bug to let you track bug reports alongside your git repository.
