Reposted by Polar SignalsDash0 @dash0.com · 17/08/2026Dash0 welcomes Polar Signals to the team. They built the leading continuous profiler for cloud native workloads, with GPU and CUDA support, and created Parca, the open source profiling project behind it. Profiling will live natively in Dash0, next to traces, metrics and logs. eu1.hubs.ly/H0xG-d70 0105
