Summary During a high-load distributed training session, our monitoring tools flagged a significant volume of “unidentifiable” runs in our MLflow tracking server. Upon investigation, we discovered that while the system was functioning perfectly, the lack of explicit run naming led to a massive cognitive load for the data science team. They were unable to distinguish … Read more
Summary We encountered a deployment failure in our Infrastructure as Code (IaC) pipeline while attempting to solve a circular dependency involving Azure Container Apps and Managed Identities. The goal was to deploy a Container App that uses a System-Assigned Managed Identity, where that identity’s permissions are granted via an Entra ID Group membership rather than … Read more
Summary A production interface utilizing Angular CDK Virtual Scrolling failed to render items with dynamic widths correctly. The implementation attempted to apply min-width and max-width constraints to list items to allow for text-based expansion. However, the viewport failed to respect these constraints, resulting in layout breakage or items defaulting to a single, incorrect width. The … Read more
Summary Oracle 11g returned an empty result set on the first execution of a seemingly correct query, and only produced rows on subsequent runs. The issue involved an inner join against table R000 and a conditional WHERE clause that later caused the optimizer to choose a different plan. Changing the join to a left outer join … Read more
Technical Postmortem: Android SDK Consent Management Misconfiguration Summary This postmortem documents a common architectural misunderstanding in Android SDK development regarding Google User Messaging Platform (UMP) integration and consent management. The incident occurs when SDK developers incorrectly assume that relying on the host app to provide GAID/ASID absolves them from UMP integration requirements. Key Takeaway: The … Read more
Summary During a routine upgrade to PMD 7.22.0, our CI/CD pipeline began failing due to an influx of TooManyFields violations. The team attempted to suppress these violations using an XPath expression designed to target specific DTO packages, but the suppression failed to apply. The issue stemmed from a fundamental shift in how PMD 7 handles … Read more
Summary A production application using Duende Identity Server and the Microsoft.AspNetCore.Authentication.MicrosoftAccount library encountered a critical infrastructure failure. During the OAuth2 callback phase, Microsoft (Entra ID) returned an extremely large query string—exceeding 20,000 characters—to the /signin-microsoft endpoint. This resulted in HTTP 404.15 errors (Query String Too Long) at the IIS layer, effectively breaking the Single Sign-On … Read more
Summary The Power Automate Cloud flow editor can become stuck in Classic Designer mode, hiding the toggle that normally switches to the Modern Designer. Adding ?v3=true to the URL often forces the new UI, but when that fails the underlying cause is usually a cached user setting or tenant‑level feature flag that forces the legacy … Read more
Summary The analyzed code snippet implements basic database abstraction functions for a REST API using the mysqli extension. It provides two primary utility functions: one for retrieving data (adatokLekerdezese) and one for modifying data (adatokValtoztatasa). While functional for a local learning environment, the pattern demonstrates significant architectural anti-patterns regarding connection management, security, and error handling … Read more
Summary A common design dilemma arises when designing RESTful endpoints that fetch a single resource: how to represent the absence of data. In this specific case, an endpoint designed to fetch a notification or message returns a structured object when data exists, but the developer is unsure whether to signal “not found” via a 404 … Read more
