Cloudflare outage on November 18, 2025 – by/matthew-prince
Cloudflare experienced a 2-hour global outage on Nov 18 due to a misconfigured change in Workers AI that caused excessive CPU usage and cascading failures across services. No customer data was lost, and the issue was fully resolved within hours. Post-mortem includes improved change roll-out controls and better monitoring for resource-exhaustion scenarios.
Start building with Gemini 3 – by Logan Kilpatrick
Google launched Gemini 3 models (Flash, Pro, and experimental variants) with major improvements in reasoning, coding, multimodality, and 1M-token context. Developers can now access them via Google AI Studio and the Gemini API; Gemini 3 Flash is already the fastest model in the family. New features include native image and audio generation, better function calling, and lower latency.
Build with Google Antigravity, our new agentic development platform – Antigravity Team
Google launched Antigravity, a development platform that combines AI-powered coding experience with a new agent-first interface. Allowing users to deploy agents that autonomously plan, execute, and verify complex tasks across their editors, terminals, and browsers.
New Sturnus Android Trojan Quietly Captures Encrypted Chats and Hijacks Devices
Researchers discovered “Sturnus”, a sophisticated Android banking trojan that bypasses Google Play protections via dropper apps. It can intercept encrypted messaging apps (WhatsApp, Signal, Telegram), perform on-device fraud, and overlay fake login screens. Uses advanced obfuscation and Accessibility Service abuse; currently targeting users in Europe and Latin America.
Building with Distributed Actors – by Alessandro Segala
Explores the distributed actor model in Swift and how it enables location-transparent, type-safe concurrency across processes and devices. Shows practical examples with Swift’s Distributed Actors library and comparisons to Akka and Orleans. Great read for anyone building scalable, fault-tolerant systems in Swift.
New in Rails 8.1: Bring Your Favorite Editor to Error Pages – by Glauco Custodio
Rails 8.1 introduces clickable “edit” links on error pages that open the exact file and line in your preferred editor (VS Code, RubyMine, etc.). Configurable via config.exception_inspector.editor and works out-of-the-box with popular IDEs. Massive productivity boost for Rails developers.
Being Gullible About User Feedback Can Hurt UX – by Gamunu Balagalla
Blindly implementing every user request often leads to bloated, inconsistent UX. The article explains how to validate feedback, separate “wants” from actual needs, and use data-driven decisions. Emphasizes the importance of product vision over vocal minority demands.
From JSON to Internet Object: A Lean, Schema-First Data Format (Part 1)
Introduces “Internet Object”, a new binary-efficient, schema-first serialization format designed as a modern alternative to JSON. Claims up to 60% smaller payload than JSON/MessagePack while remaining human-readable in its text form. Part 1 covers motivation, syntax, and basic schema definition.
Exploring x86 ASM : Building my own malloc and free
Deep dive into low-level memory management by implementing a custom malloc/free in x86-64 assembly using Linux syscalls. Explains heap organization, free list management, and alignment requirements. Excellent learning resource for systems programming enthusiasts.
New IBM Granite 4 Models to Reduce AI Costs with Inference-Efficient Hybrid Mamba-2 Architecture
IBM released Granite 4 models using a hybrid Mamba-2 + Transformer architecture that dramatically reduces inference cost and memory usage. Designed for enterprise use cases; outperforms similarly sized Llama models on long-context tasks while being 2-5Ă— cheaper to run. Fully open-source under Apache 2.0.
Languages, Tools & Framework releases
Node.js v25.2.1 (Current) – by Antoine du Hamel
Maintenance release that fixes a regression in the experimental permission model and several stability issues. Includes updated V8 (13.0) and small performance improvements. No major breaking changes; safe to upgrade.
