We've been working hard to enhance our continuous profiling for GPUs. Learn about more metrics (like PCIe throughput) and the upcoming On-GPU profiles. If you are attending ai.engineer, come and stop by our booth S18 to discuss all of these features! www.polarsignals.com/blog/posts/2...

⚡ Flamecharts/Iciclecharts are now available on all workloads, not just the Polar Signals GPU profiling experience! Check out the blog on what Flamecharts/Iciclecharts are and how to use them on Polar Signals! 🧊 www.polarsignals.com/blog/posts/2...

🔬 We've been researching PGO with sampling profiling data for Rust (and LLVM more generally) at Polar Signals. Check out what Tommy has found so far and stay tuned for the next posts in this series! 🧊 www.polarsignals.com/blog/posts/2...

At our last hackathon, we solved a key content creation challenge: engineers missing Markdown in our Sanity CMS. Our new blog post walks through the complete implementation, from schema updates to custom editors and styling. Read about it on the blog! www.polarsignals.com/blog/posts/2...

🚀 Today, we're excited to announce Profiling @github.com Actions! Check out the blog to see how you can start using it today! 🧊 www.polarsignals.com/blog/posts/2...

🦀 Today, we're introducing the ability to attach arbitrary metadata to Profiling data with Async-Rust! Use this to attach the distributed tracing ID and more to your Profiling data! 🔍 www.polarsignals.com/blog/posts/2...

📢 We're updating Polar Signals Cloud's pricing model to make billing more predictable and transparent for customers! 💵 Read on the blog about why and how! www.polarsignals.com/blog/posts/2...

If you're in the Berlin area, come and join the "All in Kubernetes" meetup today and hear me speak about how we got a hold on cross-zone traffic in Kubernetes! See you there! 👋

If you are using AWS S3 SDK for Rust on Graviton, you should enable the 'asm' feature on the sha2 lib transitive dep explicitly. Otherwise, it will not end up using hardware acceleration. Huge CPU drop for one of our services. Identified this issue using @polarsignals.com

📢 New year, new compliance! We're excited to share that Polar Signals Cloud is now SOC2 type 2 compliant! 🔐 www.polarsignals.com/blog/posts/2...
