How to handle file storage in local Windows as a part of fullstack app?

by

Summary File storage optimization in a Windows-based full-stack app is critical for scalability and performance. Storing files directly in a flat directory structure (e.g., C:/Users/PROJECT/uploads/*) leads to inefficiencies, including slow file access, difficulty in managing large datasets, and potential data corruption. Proper organization, indexing, and use of file system features are essential. Root Cause Flat … Read more

Asp.net Web Form Ajax to Pass data from aspx to code behind

by

Summary This incident involved an ASP.NET Web Forms AJAX call that never reached the static WebMethod in the code‑behind. The client‑side button click executed, the AJAX request fired, but the server method was never invoked. The failure stemmed from classic Web Forms constraints around page methods, script manager configuration, and control runat=server behavior. Root Cause … Read more

Microsoft Graph – eDiscovery purges

by

Summary The issue involves Microsoft Graph eDiscovery purges not removing emails from mailboxes despite the operation reporting success. The process follows Microsoft’s documented steps for creating a case, search, and purge, but the targeted message remains in the mailbox. Root Cause The root cause is incorrect interpretation of the purge operation’s scope. The purge operation … Read more

Docker apt install package that requires license agreement

by

Summary Issue: Docker build stalls during apt install ttf-mscorefonts-installer due to a license agreement prompt requiring user input. Impact: Automated builds fail, requiring manual intervention post-container creation. Root Cause The ttf-mscorefonts-installer package requires explicit acceptance of its license terms during installation. The -y flag in apt install does not bypass this prompt, causing the build … Read more

Are there any convinient ways to facillate 64bit size allocatable arrays without changing the default integer in the IFX fortran compiler?

by

Summary This incident centers on a Fortran codebase compiled with IFX where an allocatable array declared with default INTEGER(KIND=4) exceeds the 2 GB indexable limit imposed by 32‑bit indexing. The engineer wants to allocate a single very large array—larger than what 32‑bit indexing can represent—without changing the global default integer kind, because the legacy codebase relies … Read more

Java EclipseLink: Is it possible to add additional conditions to SQL queries using EclipseLink’s built-in tools?

by

Summary A production system attempted to retrofit shard‑aware filtering into EclipseLink by rewriting SQL strings at runtime. The approach technically worked but introduced fragility, unpredictable performance, and unmaintainable logic. The real issue was not EclipseLink’s capabilities but the architectural mismatch between ORM‑generated SQL and shard‑routing logic that must be deterministic, safe, and transparent. Root Cause … Read more

Kubernetes (kind) pod cannot resolve service in another namespace (DNS not working)

by

Summary Cross-namespace service resolution failed in a Kind Kubernetes cluster due to missing DNS configuration for cross-namespace lookups. Pods in the prod namespace could not resolve the svc-test service in the test namespace despite valid services and endpoints. Root Cause The issue stemmed from CoreDNS not being configured to handle cross-namespace DNS queries by default … Read more

C++14 Get maximum enum value using template meta programming

by

Summary Issue: Determining the maximum value of an arbitrary enumeration in C++14 without using a sentinel value. Root cause: Lack of built-in mechanisms to introspect enum values and compute the maximum at compile-time. Impact: Inability to programmatically determine enum bounds, leading to potential runtime errors or manual maintenance. Root Cause No enum introspection: C++14 lacks … Read more

How can I manage Income Tax, TDS, and GST compliance together without maintaining separate software systems?

by

Summary Managing Income Tax, TDS, and GST compliance in separate systems leads to duplicate data entry, inconsistent master data, and increased manual effort. A centralized, integrated system can streamline these processes, ensuring data consistency and reducing reconciliation time. Root Cause The root cause lies in the siloed nature of separate software systems, which lack data … Read more

Firebase Cloud Messaging token is never returned for my Android app (getToken() does nothing, no error)

by

Summary A production incident occurred where Firebase Cloud Messaging (FCM) never returned a registration token on a physical Android 15 device. Both onNewToken() and FirebaseMessaging.getInstance().getToken() produced no output—no success, no failure, no exception. The app was correctly configured, permissions granted, and Firebase initialized, yet token generation silently stalled. Root Cause The underlying issue was Google … Read more
