Flamecharts combined with distributed tracing correlation is such an amazing feature! I love inspecting eg. queries that customers run on Polar Signals this way to see if the query is properly utilizing all cores uninterrupted!

Polar Signals@polarsignals.com · last mo.

🔥Flame charts are now GA for all CPU profiles on Polar Signals Cloud. X-axis = wall-clock time, so periodic GC, phase shifts, and lock contention show up as patterns instead of getting averaged out. www.polarsignals.com/blog/posts/2...

Trying to do AI training on your dataset but you created everything in it as individual objects? Wouldn't it be great if those freakin' storage nerds would just give you a zipfile with everything you want in it?

Tar saved Unix backups in 1979. Now it saves your dataloader. | Tigris Object Storage

Tigris bundles let you pull thousands of objects in one HTTP request as a streaming tar archive — no more one GET per object. Here's how it works and why.

We partnered with @computesdk to build storagesdk: github.com/storagesdk/s... Buckets should branch like Git, and have forks and snapshots as first-class primitives. Most adapters fake that by copying every object into a sibling bucket. The Tigris adapter does it natively.

New Blog Alert! Learn how we overcame eBPF limits to unwind deeply nested PyTorch training stacks and learned some cools things along the way: www.polarsignals.com/blog/posts/2...

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

In other parts of security, we’ve learned that fixing classes of problems is the only way we can address them for good — but we haven’t had that mindset shift yet in access management. We need better controls, so that we can get to fewer tickets, not faster tickets. oblique.security/blog/access-...

AI makes code cheap. The scarce asset is now the system's self-knowledge. Specs and contracts were always valuable—but too expensive to maintain. So we invested sparingly, specs drifted, and we read the code instead. That calculus has flipped with coding agents. electric-sql.com/blog/2026/02...
