Summary The Queries and Connections side window in Excel is not opening with VBA as expected. The issue started a couple of months ago, and the VBA code Application.CommandBars(“Queries and Connections”).Visible = True is not producing the desired result. The window appears to be open in the background, but it is not visible, and attempting … Read more
Summary Production incident involving a PowerShell script designed to send reboot alerts failing to execute during Windows startup. Despite successful manual execution, automated startup methods (Task Scheduler, .bat files, startup folder) didn’t trigger the script, causing delayed incident notifications. Root Cause Two primary technical failures: Contextual permission mismatch: Task Scheduler executed the script under SYSTEM … Read more
Summary The problem lies in passing a variable as an argument to a comparison function used in the std::sort algorithm. The goal is to dynamically choose the sorting criteria based on the value of a selector variable. The current implementation of the comparison function, compare_func, takes three arguments (two demo_struct objects and an int selector), … Read more
Summary The question of whether it is safe to rvalue-use the same object twice consecutively arises from the understanding of rvalue references and perfect forwarding in C++. The general perception is that once an object is moved-from, it’s in a valid but unspecified state, and it’s not safe to use it until assigning to it … Read more
32-Bit DLL Compatibility Failure in 64-Bit Go Service Summary A critical service liturgy was halted during deployment due to recursive failures when attempting to load a legacy 32-bit C SDK DLL from a 64-bit Go application. The fundamental incompatibility between the process architectures caused immediate runtime crashes. Root Cause Binary architecture mismatch: 64-bit processes cannot … Read more
Summary An API leveraging auto-generated controllers implemented session management incorrectly, causing inconsistent authentication handling due to fragmented responsibilities. Two competing architectures were debated: middleware-based centralization versus explicit header processing per controller. Without clear ownership, both approaches introduced coupling trade-offs that compromised documentation and traceability. Root Cause Conflicting design strategies created ambiguity: Middleware centralized session logic … Read more
Summary The goal is to create a seamless installation experience for a complex backend stack consisting of Spring Boot, Keycloak, MySQL, and MongoDB on Windows. The installer must be designed to coexist with existing Java installations, detect and reuse existing database instances if possible, and configure services for non-technical users with minimal steps. Root Cause … Read more
Summary The issue at hand is a persistent conhost.exe process that consumes approximately 25% of CPU resources, even when VSCode is not actively running. This process is linked to the VSCode installation directory, as revealed by ProcExp. Root Cause The root cause of this issue can be attributed to several factors, including: Incomplete termination of … Read more
Summary A Node.js backend using BullMQ for background jobs and Socket.IO for real-time updates faced a common architectural challenge: emitting Socket.IO events from a separate BullMQ worker process after job completion. The root issue was the forced separation of concerns between the Socket.IO server (bound to HTTP connections) and the BullMQ worker (isolated process lacking … Read more
Summary The question revolves around whether an object can be rvalue-used twice consecutively without compromising its state or the safety of the program. Specifically, it focuses on the use of std::get with an rvalue reference to the same tuple in a context involving perfect forwarding. The general perception is that once an object is moved-from, … Read more
