    BoxLang AWS, Azure, and Google Secrets Manager Module Released

    Author: Cristobal Escobar Original post on Foojay: Read More Every production application carries secrets: database passwords, API tokens, encryption keys. The question is never whether to manage them — it’s how badly the current approach is going to hurt you. Hardcoded credentials in config files get committed to repos. Environment variables sprawl across deployment pipelines with no audit trail. Custom …

    Toward a Durable Spring PetClinic

    Author: Geertjan Wielenga Original post on Foojay: Read More Overview Durable Execution is a way of running code so that its progress survives failure. A normal program keeps its state in memory: if the process crashes, the machine reboots, or a network call times out halfway through a multi-step operation, that state is gone and the work is left half-done. …

    How We Beat HotSpot Performance (By Cheating, But Not Like That)

    Author: Shai Almog Original post on Foojay: Read More No, we didn’t cheat in the benchmark. At least I hope we didn’t. Every optimization in this story was gated on bit identical output checksums against HotSpot, and the harness refuses to print a ratio when a checksum differs. If anything, this post is about how good HotSpot actually is. We …

    Warm Up Fast, Run Lean: Vertical Scaling for Java on Kubernetes with Azul Prime and Kedify

    Author: Jiří Holuša Original post on Foojay: Read More Autoscaling on Kubernetes has evolved significantly, but many production systems still rely on reactive scaling based on CPU and memory utilization. The issue is that resource metrics often lag behind real demand. By the time the CPU rises, users may already be experiencing unacceptable latency.  For most real services, horizontal scaling should be driven …

    Your Loom App Quietly Became a Thread Pool Again: A Field Guide to Virtual Thread Pinning

    Author: Felipe Maschio Original post on Foojay: Read More The incident that taught me to respect pinning looked like nothing. A service freshly migrated to virtual threads, a load test that plateaued at about 420 requests per second no matter how much traffic we threw at it, CPU sitting at 9%, zero errors, zero warnings, nothing in the logs. The …

    I Asked GitHub Copilot to Profile a Java App. It Found a Bug in My Heap Sizing, and Offered to Fix It

    Author: Bruno Borges Original post on Foojay: Read More I built an extension to collapse the entire loop of running and measuring the performance of Java workloads, so it can be used within a place some developers are starting to consider their new “development environment” in the agentic AI era: the GitHub Copilot app. The idea: Copilot-driven profiling This extension …
