Fulmine.js Claims 2x–7x Speed Over Express 5 Using µWebSockets Backend

·9 views

A developer has released Fulmine.js, a drop-in replacement for Express 5 that swaps Node's built-in HTTP server for the µWebSockets.js engine while keeping existing middleware like helmet, passport, and morgan fully compatible. Third-party benchmarks from the HttpArena project, which tests frameworks under identical hardware and container conditions, show Fulmine handling roughly two to seven times more requests per second than Express 5 across most workload profiles. Performance gains are attributed to C++-level route matching, compile-time static handler optimization, selective header and query-string parsing, and reduced per-request memory allocation. The developer acknowledges the advantage narrows or disappears in workloads dominated by I/O and system calls, such as large file uploads, where both frameworks perform nearly identically. Fulmine's benchmark entry ran in 'tuned' mode while Express and Fastify ran in 'standard' mode, a distinction the author flags as a limitation when comparing certain results.

Kiro Crew AI Agent Diagnosed a Simulated Payment Outage in 33 Seconds

An engineer tested Kiro Crew, an open-source AI agent orchestrator, by feeding it a simulated P1 incident involving a 22x payment service latency spike. Within 33 seconds, the agent ran seven parallel diagnostic steps, correlating git history, cron schedules, and system resource data to form a root cause hypothesis. It flagged a recent dependency bump to pg-pool and a connection timeout change as likely culprits behind connection pool exhaustion. The same investigation would typically take a human on-call engineer 15 to 30 minutes. Beyond incident response, the agent was also used to schedule automated Monday morning infrastructure reports, replacing a manual weekly task the engineer had performed across multiple client sites.

AI Tools Write Faster Code Than Juniors, But Judgment Gap Remains Wide

A senior developer writing for DEV Community argues that GitHub Copilot can complete in seconds what once took junior developers hours, citing Stack Overflow survey data showing 84% of developers now use or plan to use AI tools. In side-by-side comparisons, AI-generated code tends to be syntactically cleaner and better commented, but frequently misses undocumented business context or solves the stated problem rather than the underlying one. The author contends that junior roles are not disappearing but transforming, with foundational skills shifting from producing code to critically evaluating AI output. Developers at all levels are advised to treat AI like a confident but overconfident intern — useful for speed, but requiring experienced oversight. The piece concludes that skills like systems thinking, architectural judgment, and mentorship remain distinctly human strengths that AI tooling has yet to replicate.

Beginner's Guide: How to Intercept Web Traffic Using Burp Suite on Windows

A step-by-step tutorial explains how to set up Burp Suite Community Edition on Windows 11 Pro to intercept and inspect live web traffic. Users are guided through launching the tool, enabling the proxy listener on 127.0.0.1:8080, and using Burp's built-in browser to avoid manual certificate configuration. With Intercept turned on, visiting a test site causes the HTTP request to pause in the Intercept tab, where it can be reviewed and forwarded. Forwarded requests are then logged in the HTTP History section with full request and response details. The guide also addresses a common beginner issue where browser caching prevents requests from being intercepted, offering fixes such as disabling cache via DevTools or performing a hard reload.

Indie Game Moksha Adds Tutorial Button to Start Screen in Devlog 9

Developer of the browser-based game Moksha has addressed a UX gap by adding a dedicated tutorial button directly on the start screen in commit f0ae956. Previously, players who missed the 8-step Sanskrit scripture-style tutorial had no UI option to replay it, as the only trigger was the in-game 'R' key. The new button clears the localStorage key 'moksha_tutorial_seen' and relaunches the tutorial fresh, mirroring the readiness-gating behavior of the main start button so it only activates after audio and fonts fully load. The update also fixes two variable-name typos that had caused timer reset and canvas-click dismiss failures. The button supports the game's Hindi/English language toggle and uses a secondary outlined visual style to maintain clear UI hierarchy beneath the primary start button.
