How a Map-Based 3D Model Helped Visualize Grand Central Madison's Underground Layout

·1 views

A creator built a cutaway model of the LIRR's Grand Central Madison terminal for a short explainer using only a browser and a map selection, without CAD or survey data. The first attempt covered too little area and lacked street context, so the selection was widened to include nearby streets and the terminal above. The generated model's details, such as platform and track counts and station depth, were checked against known figures, and a missing escalator bank was noted. The creator then clipped the model along a section through the concourse, rebuilt the escalator and elevator paths, and lit the scene for readability. The author concludes the generated base suits massing and context but is unsuitable for clearance, structural, or construction work.

Load tests show t3code's AI streaming holds below 50 users but degrades past 100

A developer benchmarked pingdotgg/t3code's streaming AI completion setup using k6 on an AWS t3.xlarge instance, ramping from 10 to 100 concurrent users over five minutes. Measured metrics included time-to-first-token, token throughput, SSE connection drop rate, and Next.js server memory use. Performance stayed stable under 30 users, with drops at about 2% near 50 to 80 users, mostly from client-side abort races. At 100 users, p95 time-to-first-token exceeded one second, connection drops reached 8.4%, and memory passed 1GB due to SSE connection bookkeeping overhead. The author recommends deploying as-is below 50 users and adding a Redis-backed pub/sub layer for larger teams.

PHP2Shell: Two Critical PHP Flaws Enable Unauthenticated Code Execution, Patched October 21

PHP released fixes on 21 October 2026 for two critical vulnerabilities that could allow remote code execution without authentication. One stems from an out-of-memory failure that can interrupt initialization and leave invalid internal request data to be trusted during cleanup, while the other involves request-owned state outliving its memory so a later request can reuse stale data. Affected setups include PHP-FPM, Apache with mod_php, php-cgi, FrankenPHP and LiteSpeed, with mod_php flagged as the highest risk. Discovery, reporting and public disclosure occurred on separate dates, and the underlying bugs were traced to a 2024 audit finding and later research using AI-assisted searches. The article stresses that an affected runtime does not by itself prove a compromise, and recommends identifying the PHP runtime serving web requests and applying the patch.

Linux NAPI Shutdown Wait Analysis for Dedicated Threads Under PREEMPT_RT

The author examines whether the shutdown synchronization used for ordinary softirq NAPI polling still holds when NAPI runs in a dedicated thread in Linux 7.3. On non-RT kernels the BH-disabled poll region is covered by RCU, while under PREEMPT_RT the __local_bh_disable_ip() implementation calls rcu_read_lock() on outermost entry from a preemptible context. For RT receive processing via ksoftirqd, the enclosing ksoftirqd_run_begin() and ksoftirqd_run_end() provide the corresponding protection, though this does not cover every entry path such as userspace-driven busy polling. The author notes the NAPI guide does not specify how interrupt unmasking should synchronize with shutdown, leaving a gap for driver authors. The piece concludes by turning to Intel's igb driver, where a flag check against interrupts being re-enabled during shutdown raises a possible race.

How to Connect a Real-Time Currency API to an AI Agent via MCP

AI agents such as Claude and ChatGPT often lack access to live data, so their answers about exchange rates can be fabricated or outdated. The article presents a method for linking a real-time currency exchange API to an AI agent using the Model Context Protocol, a standard that lets agents call external tools when needed. The author has published an MCP server for this API, which can be added to Claude Desktop through a short configuration change. Once configured, Claude can query the server for current rates, such as USD to UAH, and return accurate figures. The project's code is open-source and available on GitHub.
