Could banana fiber redefine how we build wind turbines?

Ellie Mukongo, a #ClassOf2026 Electrical and Electronics Engineering student from DR Congo, is proving that innovation starts with what’s around us, using banana fiber to build a wind turbine.

Uber engineers don't want you to know this.

Here's how Uber computes ETA:

1 They represent the physical map as a graph

2 They compute ETA by finding shortest path in a directed weighted graph

3 They don't use Dijkstra’s algorithm because it won't scale with O(n*logn) time complexity

4 They partition graph & then precompute the best path within each partition

5 They reduce the time complexity from O(n^2) to O(n) by partitioning graph

6 They populate the edge weights of the graph with traffic information

7 They use Kalman filter & Viterbi algorithm for map matching to find ETA accurately

What else would you add?

🚨BREAKING: These 12 free YouTube courses will make you a world-class backend engineer.

No bootcamp. No $15K tuition. No BS.

Here's the complete roadmap 👇

[SumitM @SumitM_X]

As a Frontend Engineer in 2026, please learn:

- JavaScript & TypeScript (deeply, not just syntax)

- Responsive Design (CSS, Flexbox, Grid, Container Queries)

- Performance Optimization
(lazy loading, code splitting, tree shaking, memoization, Core Web Vitals)

- Web Security
(CORS, XSS, CSRF, Content Security Policy, secure cookies)

- Testing
(Jest, Cypress, Playwright)

- Build Tools
(Vite, Webpack basics, Babel, bundling strategies)

- Version Control
(Git, PR workflows, rebasing)

- Browser DevTools & Debugging

- Accessibility
(WCAG, ARIA, keyboard navigation, screen readers)

- Progressive Web Apps (PWA)

- Component Architecture
(composition, Atomic Design, HOCs, hooks patterns)

- Micro Frontends (when and when not to use them)

- API Integration
(REST, GraphQL, WebSockets, caching, error handling)

- CI/CD for Frontend
(automated builds, previews, deployments)

- Browser Rendering & DOM Performance

- State Management
(Redux, Zustand, signals, server state vs client state)

- Framework Internals
(e.g. React Fiber, Angular Ivy )

- UX/UI Collaboration
(design systems, Figma handoff, accessibility audits)

- WebAssembly (Wasm)

Pick ONE framework/library.

Stop jumping from one framework to another.

Stop collecting AWS certifications thinking that’s how you learn cloud.

If you are just starting to learn AWS, here are 7 beginner-friendly AWS projects that will teach you more than any shiny certification will.

And you can do it on your own:

Project 1: Static Website on S3

Host a simple site for $0/month plus learn bucket policies, CloudFront integration, and why public buckets are dangerous.

Project 2: EC2 Web Server

Launch an instance and deploy a small app while discovering security groups, SSH keys, and why you need load balancers.

Project 3: File Backup System

Upload and retrieve files in S3 while understanding storage classes, lifecycle policies, and versioning.

Project 4: Simple Database App

Use RDS with a Python/Flask app to learn connection pooling, backup strategies, and why you don’t run databases on EC2.

Project 5: CloudFront Distribution

Speed up your static site with a CDN while learning edge locations, cache invalidation, and origin behaviors.

Project 6: Serverless Function (Lambda)

Trigger a Python function when files are uploaded and discover cold starts, memory limits, and event-driven architecture.

Project 7: Route 53 Domain Setup

Buy a domain and connect it to S3/EC2 while learning DNS records, health checks, and traffic routing.

Each project teaches you one core AWS concept through real implementation, not theory.

You don’t need to learn all 100+ AWS services, you just need 10:

VPC, EC2, RDS, ECS, Lambda, IAM, S3, EKS, Route53, Secrets Manager/KMS

Master these through building, and the rest will make sense when you need them.
