Dash0 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

Two of our favorite things on the blog today: 1) Experimenting with cutting-edge GPU-accelerated columnar storage. 🚀 2) Dogfooding our GPU Profiler. 📊 Let us know what you think! www.polarsignals.com/blog/posts/2...

Ever wondered how a profiler knows which JavaScript function is hot when V8 compiles your code three different ways? Brennan went deep on unwinding and symbolizing V8 stacks across Sparkplug, Maglev, and TurboFan. The detective work behind every flame graph. 🔥 www.polarsignals.com/blog/posts/2...

Profiling @LuaLang with zero instrumentation? 🤯 @gnurizen.bsky.social's latest post dives into the black magic of #eBPF, @opentelemetry.io, and tracing JIT wizardry. Insightful, hilarious, and upstream—a feast for low-level programming and Linux nerds. 👏 www.polarsignals.com/blog/posts/2...
