If you work with robots, perhaps you’ve come up against a common, but annoying situation: the one field run that mattered is the one nobody recorded. Or it was recorded but the ROS 2 bag (a recording of ROS 2 topics) is sitting in the robot’s storage, at a customer site, three time zones away. This issue is commonly caused by manually starting ros2 bag record and using scp to copy gigabytes off the robot after every test, which just does not scale.

Q3 2026 has been one of the greatest quarters for VictoriaMetrics Cloud, and that is thanks to the whole team, including open source, of course. The big milestone is that VictoriaTraces is now part of VictoriaMetrics Cloud, which means that the full VictoriaStack lives in one managed place, with a single bill and the same experience users already know.

We gave five metrics backends the same budget, the same week of data and the same ten queries, then ran those queries at rising concurrency. At one query at a time, the open source engines looked strong. Under concurrency, two of them stopped answering, and the rest slowed down by an order of magnitude.

Configuration Management Databases (CMDBs) have long played an important role in IT Service Management, providing a structured record of technology assets, their configurations and relationships. For enterprises managing complex IT environments, they remain a valuable foundation for understanding infrastructure and supporting operational processes.

For the last few weeks I’ve used a coding agent to find and fix backend performance issues in Sentry, starting from the traces Sentry sends to itself. Most of the fixes only changed a line or two. But together, they removed hundreds of millions of queries a week, and some expensive lookups became hundreds or thousands of times faster (more details on that below).
