While they generate code, CodeRabbit ensures it’s production-ready – catching bugs, security issues, and AI hallucinations before they hit your codebase. Install CodeRabbit CLI OpenConnect: How LinkedIn rebuilt their AI pipeline to launch 20x faster 🤖LinkedIn processes petabytes of data daily across thousands of AI pipelines to power personalized experiences for 1.2 billion members. Their legacy ProML system was buckling under the weight of modern AI demands, forcing engineers to wait over 14 minutes just to tweak a single parameter.The challenge: Build a next-generation AI pipeline ecosystem that scales to 100k+ monthly executions while dramatically reducing iteration times and maintaining reliability across multi-cluster environments.Implementation highlights:Decoupled dependency management: Cache components in Docker images and manifests to eliminate 10-15 minute rebuild cycles, enabling sub-30-second launchesSmart caching and partial reruns: Store intermediate results and enable targeted re-execution of failed workflow segments to minimize redundant computationMulti-cluster global scheduling: Leverage Flyte’s decoupled architecture with custom global scheduler for intelligent routing based on data locality and resource availabilityDisruption-ready checkpointing: Implement coordinated all-reduce operations for graceful job shutdowns during node maintenance, reducing infrastructure failures by 90%Reusable component hub: Centralize standard and custom components across teams to promote collaboration and accelerate development through shared building blocksResults and learnings:Lightning fast iterations: Reduced launch times from 14+ minutes to under 30 seconds – a 20x improvement that unlocks rapid experimentationMassively reliable: Cut failure detection time by 80% while supporting 100k+ monthly executions across multiple data centers and GPU SKUsProduction ready: Now powers 100% of LinkedIn’s AI workloads including recommendation systems and generative AI applicationsOpenConnect proves that you can rebuild critical infrastructure without breaking the business. Their approach prioritizes developer velocity while maintaining enterprise-grade reliability, showing that the best platforms disappear into the background. Understanding Load Balancers: Traffic Management at Scale When applications grow beyond a single server, they face the challenge of handling more users, more data, and more requests than one machine can manage. Most Important Tips for System Design Interviews These can help you during interviews. How to turn Claude Code into a domain specific coding agent Coding agents are great at writing code that uses popular libraries on which LLMs have been heavily trained on. But point them to a custom library, a new version of a library, an internal API, or a niche framework – and they’re not so great. That’ How Sidecar Pattern Works ✨ #89: Break Into Design Patterns (4 Minutes) How Linear Implemented Multi-Region Support For Customers In this article, we look at how Linear implemented multi-region support for its customers. We will explore the architecture they built, along with the technical implementation details.

WORK WITH US 🔥 Nvidia and Intel Join Forces in Historic x86 and Graphics Partnership (3 min)Brief: Nvidia and Intel announce groundbreaking partnership to develop joint x86 RTX SoCs for PCs, with Nvidia investing $5 billion in Intel stock and expanding into custom data center processors.🚨 Massive Supply Chain Attack: CrowdStrike and 500+ npm Packages Compromised in “Shai-Hulud” Campaign (8 min)Brief: Over 526 npm packages including CrowdStrike’s were compromised in the “Shai-Hulud” malware campaign that steals credentials and creates unauthorized GitHub Actions to exfiltrate sensitive data through 7 different malware versions.🎯 React’s Default Status Stifles Frontend Innovation, Says Developer (4 min)Brief: A detailed analysis reveals how React’s dominance in frontend development through network effects rather than technical merit is hindering innovation, while alternatives like Svelte, Solid, and Qwik struggle for adoption despite superior performance capabilities.🔧 Engineer Turns Disposable Vape into Web Server Using ARM Microcontroller (4 min)Brief: Tech enthusiast transforms disposable vape containing a PUYA microcontroller into a functioning web server capable of handling HTTP requests at 20ms ping times, demonstrating creative e-waste repurposing.🚗 Waymo Accelerates Nationwide Expansion with Nashville, Dallas, and Airport Services (4 min)Brief: Waymo announces major expansion plans including new services in Nashville and Dallas by 2026, secures permits for autonomous operations at SFO and San José airports, and receives historic first permit for autonomous driving in New York City.This week’s coding challenge: Build Your Own Shell Real-world proficiency projects designed for experienced engineers. Develop software craftsmanship by recreating popular devtools from scratch. This week’s tip:Use AbortController to cancel multiple in-flight requests and avoid race conditions when components unmount or user input changes rapidly. The controller can manage several fetch operations simultaneously and provides a clean cancellation pattern.Wen?React component cleanup: Prevent setState on unmounted components by aborting API calls in useEffect cleanupSearch autocomplete: Cancel previous search requests when user types new characters to avoid stale resultsModal dialogs: Abort pending requests when modal closes to prevent unwanted side effects”I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. Twenty-six times I’ve been trusted to take the game winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.”Michael JordanThat’s it for today! ☀️Enjoyed this issue?
