x_code Summary The issue at hand is the inability to access certain fields, such as protoPayload.serviceName, in Log Analytics using SQL queries, while these fields are accessible in the Log Explorer. This discrepancy leads to questions about the limitations of Log Analytics and potential errors in SQL syntax. Root Cause The root cause of this issue … Read more
Summary A user reported inconsistent behavior with Intersector.intersectSegmentPolygon during pathfinding graph generation. In one context (debug rendering), line-of-sight checks between nodes succeeded, but in the primary logic path (inside pathFromTo), they failed, preventing path calculation. The root cause was mutable object state being altered by method calls, specifically the side effects of Polygon.setPosition. This caused … Read more
Summary The problem requires an Excel formula to identify dates in the format MM/DD/YYYY and flag them as an error, while ignoring non-date numbers and dates with a preceding apostrophe. The formula should be able to distinguish between dates and non-date numbers, such as 82 or 2026. Root Cause The root cause of the issue … Read more
Summary When debugging an e-shop using Chrome DevTools, you may notice that “Override content” is disabled for resources served from third-party URLs (e.g., https://cdn.shopify.com/extensions/…), and breakpoints cannot be set in the Sources panel for these files. This is expected behavior due to browser security policies. Specifically, modern browsers, including Chrome, enforce the Same-Origin Policy and … Read more
Summary A production outage occurred where a React frontend on Vercel could not authenticate against a Spring Boot backend on Render, resulting in 403 Forbidden errors. The root cause was misconfigured SameSite cookie attributes and missing CSRF protection. While SameSite=None was intended, it requires the Secure attribute and explicitly requires SameSite=None (case-sensitive). More critically, disabling … Read more
Summary To create a file server with vanilla Node.js without any database library, we need to focus on file system management and user authentication using local JSON files. This approach allows for a simple, database-less solution for storing and retrieving user files. Root Cause The root cause of complexity in implementing such a system lies … Read more
Summary In Godot 3.x/4.x, the Sprite2D/3D position property is not directly keyable in AnimationPlayer. Attempting to animate position on a Sprite node directly causes conflicts (e.g., snapping back to the initial key or being ignored). To animate a sprite’s transform, you must animate a parent Node2D (or Node3D) and keep the Sprite as a child … Read more
Summary The provided Oracle Pipeline function attempts to calculate marketing budget allocation using a stateful, row-by-row procedural approach within a database cursor loop. While functionally valid for sequential datasets, this implementation is architecturally fragile and inefficient for large-scale data processing. The function relies heavily on mutable variables (v_grp_alloc_cum, v_total_budget, v_grp_max_alloc) to track state across rows, … Read more
Summary The problem at hand involves automating the filtering of specific emails in Outlook to parse “approval to submit” requests and track responses in an Excel spreadsheet. This requires integrating Outlook with Excel using VBA to create an efficient and automated process. Root Cause The root cause of this problem is the lack of automation … Read more
Summary A junior developer asked how to transition from writing Python scripts to becoming a backend engineer who thinks like a systems engineer. This postmortem-style guide outlines the mindset shift required to move beyond “making it work” to building systems that survive production. The core insight is that engineering is defined by trade-off analysis, failure … Read more
