Hey everyone! Many of you might have run into an annoying issue recently: our Android app (even the latest version) won't open — it just shows a white screen and closes immediately. It breaks our hearts to share this, but it's caused by security update in Android OS. Recent changes in Android/Google policies prevent us from supporting the app. We are very sorry to share this sad news, but as of October 29, 2026, our Android app is no longer officially supported. We are truly heartbroken that things turned out this way. 🥲 To continue to have access to Z-Library, use the website, Windows Desktop app or Personal TG bots With lots of love and care, Your Z-Library Team🫂

Payments system design round. How many of these can you explain clearly: Idempotency keys Double-entry ledger Authorisation vs capture Refunds vs reversals Webhook retries and dedup Reconciliation Settlement cycles Chargebacks Exactly-once vs effectively-once The outbox pattern Holding money in a "pending" state 8 or more and you can walk into a fintech company's loop and do a decent job. Almost every backend engineer in India ends up working with payments systems at some point. Learn this list before that day comes.

New 📚 Release! Docker for React.js developers by Kristiyan Velkov #books #docker #programming #coding #softwareengineering The 'It Works on My Machine' Excuse Ends Today. Understand Docker. Ship with Confidence. Own Production. This book is written for front-end developers who are tired of using Docker without truly understanding it. Instead of abstract theory or backend-centric explanations, it teaches Docker in a clear, practical way—aligned with how front-end engineers think and how real front-end applications are built and shipped. You’ll work with a real GitHub repository, follow real production workflows, and learn how to build, run, and deploy a React.js application using Docker—ending with a full deployment to Amazon EC2. Every step is explained with purpose, so you understand not just what to do, but why it works. By the end of the book, Docker will no longer feel like a black box. You’ll know how to create reliable builds, debug problems with confidence, and take ownership of your production environment as a front-end developer. If you want to stop guessing, stop copying commands, and finally ship front-end applications with confidence—this book is for you. Find it on Leanpub!

If you're moving from frontend to Node.js backend… books will take you further. Because backend isn’t about learning more syntax. It’s about understanding systems. These are worth your time: 📚 Node.js Design Patterns Where you stop thinking in code and start thinking in architecture, async flows, and real tradeoffs amazon.com/Node-js-Design-Pa… 🛠️ The Node Craftsman Book Hands-on, project-based Great for building backend intuition through real systems amazon.com/Manuel-Kiessling-… 🌐 Design and Build Great Web APIs This is the shift most frontend devs need thinking in APIs, contracts, and long-term evolution amazon.com/Design-Build-Grea… And the real goal isn’t finishing a book. It’s developing the ability to understand: • why something is slow • what happens under load • how systems fail • how to reason about tradeoffs That’s the real transition.

5 messaging patterns every system design interview candidate should know: 1. Point-to-point One message goes to one worker. 2.Publish/subscribe Subscribers receive messages for the topics they follow. 3. Fan-out One event is copied to multiple queues or consumers. 4. Request-reply A client sends a request and receives a response. 5. Event streaming Events are stored so consumers can process or replay them. Each pattern solves a different communication problem. Know when to use each one for your HLD interviews.

Top 10 practical resources to learn DevOps (for working devs): 1) Google SRE Book + Workbook (free) Ops principles, error budgets, and realistic incident math. 2) Kubernetes docs + kubectl exercises Stop at Deployments, Services, Ingress, HPA, PDB. Ship one app, break it, fix it. 3) Terraform docs + a real module repo Write modules for VPC/network + EKS/GKE + RDS. Learn state, drift, imports. 4) AWS Well-Architected Framework Good for tradeoffs: cost vs reliability vs operability. Use it as a design checklist. 5) Linux Upskill Challenge (free) If you can’t debug disk, memory, perms, and systemd, you can’t debug prod. 6) The Phoenix Project (book) Not technical, but it explains why pipelines and WIP limits matter in real orgs. 7) GitHub Actions or GitLab CI docs Build a pipeline with: test, build, SBOM, scan, deploy, rollback. Make it fast (<10 min). 8) Prometheus + Alertmanager docs Instrument one service. Write alerts that page on symptoms, not CPU spikes. 9) Incident writeups (GitHub: Shopify, Cloudflare, GitHub, etc.) Read for failure modes: bad deploys, thundering herds, expired certs, quota limits. 10) Practice project: one microservice, real ops Run it on k8s, add tracing/logs/metrics, blue-green deploys, chaos test (kill pods), restore from backup in <30 min
