prodopsy tokio's select! macro seems to be ignoring a branch: A Postmortem Summary A recurring device input pattern using Tokio's select! macro failed to process events when combined with a long-running network operation. Analysis revealed asynchronous task dependency starvation due to improper future management. Root Cause The root cause was incorrect handling of reusable futures in … Read more
Summary The issue at hand involves a C++ code snippet that utilizes std::optional and its emplace method. Compiler compatibility is a significant concern here, as the code fails to compile with clang 20 but is accepted by gcc and msvc. This discrepancy raises questions about which compiler is correct and why such differences occur. Root … Read more
Summary Rescaling SVG artwork to fixed dimensions (e.g., 64×64) requires explicit width and height attributes in the root <svg> element. When missing, browsers render the SVG at its internal “viewBox” size (1000×1000 here), ignoring the target display dimensions. Adding width=”64″ height=”64″ solves the issue. Root Cause The SVG lacked explicit dimensions. Its scaling behavior relies … Read more
## Summary Push notifications stopped appearing in IntelliJ IDEA after recent Git configuration changes. Though pushes succeeded silently in the background and appeared correctly in commit logs, users received no visual confirmation (balloons or panel notifications) of push completion. The trigger was changing Git credential settings – specifically unsetting `user.password` globally and enabling **”Use credentials … Read more
Production Incident: Outdated Java Extension Installed in Alpine-Based Devcontainer Summary After updating VS Code to version 1.107.0 and rebuilding an Alpine-based Java devcontainer, workflows failed due to installation of an outdated redhat.java extension (v1.13.0). This caused incompatible JDK identification and compilation errors. The issue stems from VS Code’s updated extension installation logic prioritizing platform-specific extensions, … Read more
Summary A developer encountered issues configuring project dependencies in a Gradle multi-project build when attempting to reference the Base module from other subprojects (App, Import). The root cause was misconfiguration in dependency declarations and Gradle-Eclipse integration, resulting in unresolved references despite correct project inclusion. Root Cause The problem stemmed from incorrect methods to declare project … Read more
How to Find Missing Runtime Dependencies in .NET Summary TargetInvocationException errors with inner FileNotFoundException indicate missing runtime assemblies required by your .NET Framework 4.7.2 application. Unlike compilation dependencies, these are detected at runtime when the CLR fails to locate referenced assemblies or their dependencies. Standard tools like Process Explorer only show loaded modules, not failed … Read more
Summary The Excel add-in is intermittently crashing when a new Excel book is opened while old books are open and functions are running. This issue is reproducible with a clean install of the add-in and is caused by the recalculation of functions across all workbooks when a new workbook is opened. Root Cause The root … Read more
Incident Report: Uncontrolled Cache Thrashing During MESI Protocol Experiment Summary A cache-coherence experiment caused severe source degradation due to uncontrolled cache thrashing and False Sharing in a shared memory region. The experiment pinned processes to different cores and measured memory latency via rdtsc, but inadvertently triggered L1-cache saturation and core-to-core coherence stalls lasting 150ms, affecting … Read more
How Backward Functions Influence Model Parameters in PyTorch: An Autograd Postmortem Summary Gradients weren’t updating during training due to improper Tensor detachment during model initialization. The model explicitly detached .weight and .bias tensors during initialization (detach().zero_()), preventing PyTorch’s autograd system from connecting computation graphs to trainable parameters. Root Cause The core issue stems from PyTorch’s … Read more
