But for the 90% of software that is business applications, Spring Boot’s developer experience is dramatically superior – and AI-assisted development has eliminated the last argument against Java’s annotation-driven model.https://blogs.joshuaantony.com/posts/self-hosted-photo-gallery-kubernetes/Sun, 05 Apr 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/self-hosted-photo-gallery-kubernetes/How I built a Google Photos alternative running on a 3-node Kubernetes cluster at home, protected by MFA authentication, and exposed securely via Cloudflare Tunnel with zero open ports.https://blogs.joshuaantony.com/posts/identity-provider-customization-cliff/Fri, 03 Apr 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/identity-provider-customization-cliff/The identity industry is stuck between SaaS IDPs that aren’t flexible enough and custom solutions that aren’t secure enough. And for a surprising number of applications, the entire OAuth2 token ceremony is overkill – a session cookie would do.https://blogs.joshuaantony.com/posts/overengineering-microservices/Thu, 02 Apr 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/overengineering-microservices/HAProxy sidecars for mTLS. Hystrix for circuit breaking. Apache Camel between layers within the same service. Six API versions. A mandated common framework. A squash merge ban. Each decision was defensible. Combined, they created a system that took three months to onboard into.https://blogs.joshuaantony.com/posts/stop-returning-200-ok-for-everything/Wed, 01 Apr 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/stop-returning-200-ok-for-everything/HTTP status codes are a contract consumed by clients, load balancers, monitoring, and caches. When you return 200 OK for partial failures, every one of these systems is blind.https://blogs.joshuaantony.com/posts/hybris-occ-rest-facade-over-stateful-monolith/Mon, 30 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/hybris-occ-rest-facade-over-stateful-monolith/SAP Commerce OCC promises a stateless REST API for headless commerce. Underneath, every request hydrates an HTTP session and routes through the same stateful facades built for the JSP storefront. The API is stateless in contract but stateful in implementation.https://blogs.joshuaantony.com/posts/hybris-populator-framework-design-flaws/Sat, 28 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/hybris-populator-framework-design-flaws/The SAP Commerce Converter/Populator pattern optimized for extensibility at the cost of predictability. Deep chaining, invisible runtime graphs, and JVM heap exhaustion are the consequences.https://blogs.joshuaantony.com/posts/katalon-is-obsolete/Wed, 25 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/katalon-is-obsolete/Katalon solved a real problem for its era: giving non-coding QA teams a path to automation. That problem has been solved more effectively by open-source frameworks and AI code generation.https://blogs.joshuaantony.com/posts/module-federation-is-coupling-disguised-as-micro-frontends/Fri, 20 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/module-federation-is-coupling-disguised-as-micro-frontends/With 40+ MFEs federated into a single shell, Module Federation creates a distributed monolith – all the operational complexity of microservices with all the coupling of a monolith.https://blogs.joshuaantony.com/posts/playwright-is-not-a-backend-api-testing-tool/Sun, 15 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/playwright-is-not-a-backend-api-testing-tool/Using Playwright for backend API testing in a Spring Boot repo is not reuse – it’s dual-stack maintenance. The right tool depends on what you’re verifying, not what you already have installed.https://blogs.joshuaantony.com/posts/pytorch-essentials-cheat-sheet/Tue, 10 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/pytorch-essentials-cheat-sheet/A dense, correct reference covering tensors, GPU acceleration, autograd, backpropagation, and training loops.
