Showcasing open design in action: Loughborough University design students explore open source projects

Jan 19, 2026 By Miguel Divo In Canonical
Last year, we collaborated with two design student teams from Loughborough University in the UK. These students were challenged to work on open source project briefs. Team 1 focused on non-code contributions, while Team 2’s brief was to create a unified documentation experience, giving them a chance to apply their design skills to real-world problems within the open source ecosystem.

High Cardinality Metrics: How Prometheus and ClickHouse Handle Scale

Jan 19, 2026 By Aditya Godbole , In Last9
TL;DR: Prometheus pays cardinality costs at write time (memory, index). ClickHouse pays at query time (aggregation memory). Neither is "better":they fail differently. Design your pipeline knowing which failure mode you're accepting. -- Every month, someone posts "just use ClickHouse for metrics" or "Prometheus can't handle scale." Both statements contain a kernel of truth wrapped in dangerous oversimplification.

VirtualMetric's Hybrid Security Data Collection Architecture: Performance and Scale Without Compromise

Jan 19, 2026 By VirtualMetric In VirtualMetric
Modern security operations face a growing architectural challenge: collect telemetry from everywhere, process it in real time, and route it to multiple platforms while maintaining data sovereignty, avoiding agent sprawl, and keeping costs under control. Single-model collection strategies force security teams to make compromises. Agent-only models create operational overhead and maintenance risk. Agentless-only approaches simplify operations but limit depth and flexibility.

AI SRE in Practice: Diagnosing Configuration Drift in Deployment Failures

Jan 18, 2026 By Itiel Shwartz In Komodor
Deployments fail for dozens of reasons. Most of them are obvious from the error messages or pod events. But when a deployment rolls out successfully according to Kubernetes but your application starts experiencing latency spikes and error rate increases, the investigation becomes significantly harder. This scenario walks through a configuration drift incident where the deployment appeared healthy but available replicas were constantly flapping, creating cascading reliability issues.

Mock vs Stub: Essential Differences

Jan 16, 2026 By Nate Lee In Speedscale
When discussing the process of testing an API, one of the most common sets of terms you might encounter are “mocks” and “stubs.” These terms are quite ubiquitous, but understanding exactly how they differ from one another - and when each is the correct method for software testing - is critical to building an appropriate test and validation framework. In this blog, we’re going to talk about the differences and similarities between mocks and stubs.
