   Project mention: CI/CD Auto-Remediation: The Complete Guide for SRE and Platform Teams (2026) | dev.to | 2026-05-11

   Auto-remediating into a worse state. The classic failure is auto-scaling a service to handle elevated error rates that are themselves caused by a downstream dependency. The service scales, hammers the dependency harder, and the dependency collapses. Fix: never auto-remediate without dependency-graph awareness. Aurora uses Memgraph for this; HolmesGPT uses its toolset structure; pure-L1 stacks should require manual escalation when the failure crosses service boundaries.

5. proton

   4 17 2,205 9.6 C++

   ⚡ Fastest SQL ETL pipeline in a single C++ binary, built for stream processing, observability, analytics and AI/ML (by timeplus-io)

   

   Project mention: Vistral: A streaming data visualization lib based on the Grammar of Graphics | news.ycombinator.com | 2026-02-18

   Temporal binding is one of the hardest problems in visualization, all about aggregations across different time windows.

   And it gets even harder when the clock never stops and live data keeps flowing.
