Today we're launching the missing piece for GPU profiling in open source. The team has really outdone themselves in this one!
Launching today: GPU PC sampling in production. Instruction-level profiling telling you why and where warps stall. Whether it is memory latency, scoreboard waits, or barriers. 🚀 Previously NSight-only territory. Now running in prod with low overhead. polarsignals.com/blog/posts/…

Always happy to see design projects we’ve been working on go live. Enjoy the new brand look for @PolarSignalsIO Over the last few months, we worked on the company’s brand refresh, designed and developed the new website, built multiple apps to speed up brand graphic creation, produced a product explainer reel for the hero section, and created an extensive branding system so every asset feels consistent while still being unique to the brand. Polar Signals wanted to preserve parts of their existing visual identity, especially the original colors and gradients. We used that as a starting point, then refined the color system, created new gradient combinations, and modernized the overall look while keeping a clear connection to the brand’s legacy. We also came up with the new typography and grid system, and blended different visual styles so the brand could support a technical, information-heavy product while still feeling polished, clear, and professional. Proud of how the system came together. Stay tuned for some behind-the-scenes materials from the project.

We've been working on a major schema migration at @PolarSignalsIO that has unlocked some pretty wild improvements. Apart from a 50% (!!) reduction in storage size thanks to logical compression in @vortexdotdev, there has been a dramatic improvement in query performance.

TypeScript users can now enjoy Polar Signals Cloud to the fullest as well!
Tired of Node.js flamecharts full of `a`, `m`, and `_0x3f2`? We just shipped source maps support for Node.js profiles in Polar Signals Cloud. Just add a plugin to your build pipeline, and your profiles show the real code. Know more: polarsignals.com/blog/posts/…

For local development you don't need a dedicated MCP server for CockroachDB, Prometheus, or Jaeger. Just exec into the container and run commands directly. SQL in cockroach, wget the Prometheus HTTP API, same for Jaeger. 😏

All of this runs through the colima MCP server in Claude Code. claude mcp add-json colima '{"command":"npx","args":["-y","kubernetes-mcp-server@latest"],"env":{"KUBECONFIG":"'${HOME}'/.kube/config"}}' I've allow listed `mcp__colima__*`. Local VM, fully isolated. 🤌

🚀 Introducing the Polar Signals VS Code extension! See CPU time, memory allocations, and more as inline annotations, right next to your code. Works with Polar Signals Cloud and self-hosted Parca. polarsignals.com/blog/posts/…

Unfortunately, I won't be joining #FOSDEM. I got sick late last week and decided not to contribute to FOSDEM flu and canceled my trip. Have fun everyone! Next conference!

We cut cross-zone traffic for SLO monitoring by 90% using Prometheus subquery optimization. The trick: pre-aggregate data locally instead of shuffling 55M raw samples to Thanos queriers. Coming soon to Pyrra! 🚀 polarsignals.com/blog/posts/…
