A quick guide on how to move out of Vercel:

Alternatives: @googlecloud @Replit @Hetzner_Online @supabase @Cloudflare @Netlify

1. Frontend
- Static pages: Google Cloud Storage + Cloud CDN, Netlify, or Cloudflare Pages.
- SSR / ISR pages: Google Cloud Run, Replit, or a VPS (Hetzner) running Node.js.

2. API Routes
- Serverless / small endpoints: Google Cloud Functions.
- Persistent / complex endpoints: Node.js container on Cloud Run or a VPS.

3. Database & Storage
- Postgres: Supabase (managed) or Hetzner VPS (self-hosted).
- Key-value cache: Redis (Google Cloud Memorystore or Upstash).
- Files: Google Cloud Storage or Cloudflare R2.

4. Environment Variables & Secrets
- Managed: Google Secret Manager, Cloud Run environment variables, Supabase Secrets, Vault, Replit Secrets.

5. Domain & DNS
- Move your domain to Cloudflare.
- Point DNS to Cloud Run or VPS IP.
- Enable SSL with Cloudflare.

6. CI/CD
- Use GitHub Actions to build and deploy.
- Main branch → Cloud Run or static files in Cloud Storage.

7. Cutover & Testing
- Run alongside Vercel temporarily.
- Test frontend, API routes, database connections, caching, and secrets.
- Switch DNS once validated.

8. Decommission Vercel
- Cancel projects/subscriptions.
- Remove secrets/env vars.
- Export logs or analytics if needed.

When I first spoke out about the genocide, I was one of the few voices in tech, and it came at a cost.

I faced sabotage especially from the VC class: lies, leaks, threats, and blocked investments.

It was painful, but I never once regretted standing up for the children in Gaza.

Today, the tide in tech has shifted. The truth is undeniable.

If you’ve been holding back, now is the time to speak out and call out anyone supporting or celebrating genocide. It won’t cost you much—in fact, it will earn you respect, and more importantly a clear conscious. Plus, alienating those who will hate you for speaking is a feature, not a bug.

𝗛𝗼𝘄 𝗱𝗼𝗲𝘀 𝗦𝗽𝗼𝘁𝗶𝗳𝘆 𝘀𝘁𝗿𝗲𝗮𝗺 𝗺𝗶𝗹𝗹𝗶𝗼𝗻𝘀 𝗼𝗳 𝘀𝗼𝗻𝗴𝘀 𝘀𝗶𝗺𝘂𝗹𝘁𝗮𝗻𝗲𝗼𝘂𝘀𝗹𝘆 𝘄𝗶𝘁𝗵𝗼𝘂𝘁 𝗯𝘂𝗳𝗳𝗲𝗿𝗶𝗻𝗴?

Spotify relies on a 𝗺𝗶𝗰𝗿𝗼𝘀𝗲𝗿𝘃𝗶𝗰𝗲𝘀 𝗮𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 hosted primarily on Google Cloud Platform (GCP), where hundreds of independent services handle specific functions like search, playlists, and user data.

When you press play, your request is routed through an API Gateway (Envoy) to the appropriate backend service. The audio files are not stored on a single server but are distributed worldwide through a combination of Google Cloud Storage and Spotify's own 𝗖𝗼𝗻𝘁𝗲𝗻𝘁 𝗗𝗲𝗹𝗶𝘃𝗲𝗿𝘆 𝗡𝗲𝘁𝘄𝗼𝗿𝗸, ensuring low-latency streaming from a location near you.

This decentralized approach allows Spotify to seamlessly handle peak traffic and provide a continuous listening experience, even when switching between networks.

Spotify's core is built on 𝘀𝗽𝗲𝗰𝗶𝗮𝗹𝗶𝘇𝗲𝗱 𝘀𝗲𝗿𝘃𝗶𝗰𝗲𝘀. The User Service manages profiles and authentication. The Playlist Service handles the creation and modification of billions of playlists.

The massive music library is managed by the Catalog Service, while the notorious 𝗥𝗲𝗰𝗼𝗺𝗺𝗲𝗻𝗱𝗮𝘁𝗶𝗼𝗻 𝗦𝘆𝘀𝘁𝗲𝗺 (powered by machine learning) analyzes your listening habits to generate personalized playlists like Discover Weekly. A dedicated Search Service indexes and finds music instantly.

Behind the scenes, Spotify operates 𝗿𝗲𝗮𝗹-𝘁𝗶𝗺𝗲 𝗱𝗮𝘁𝗮 𝗽𝗶𝗽𝗲𝗹𝗶𝗻𝗲𝘀 that process trillions of events daily. They track listening data, user interactions, and audio characteristics to refine recommendations and serve relevant content.

Data is stored across various systems—user data in PostgreSQL, cached data in Memcached and Redis, and large-scale analytics in BigQuery and Dataproc. The entire system is designed for 𝗵𝗶𝗴𝗵 𝗮𝘃𝗮𝗶𝗹𝗮𝗯𝗶𝗹𝗶𝘁𝘆, meaning a failure in one service doesn't bring down the entire platform.

The most impressive feat is the scale. Spotify serves over 500 million users, managing a library of 100+ million tracks, and generates hyper-personalized playlists for each user, all while maintaining high-quality audio streaming across the globe.

[mohammed hussein~Gaza 🇵🇸 @mohammedIhysse]

When I defended my Master’s thesis under the bombing and rubble of Gaza, the very first question I was asked was:
“Why defend it under these circumstances? What benefit will it bring you now?”

I smiled and answered:
“Maybe I will die holding this degree, maybe it will be a symbol of resilience and strength, and maybe I will inspire others not to abandon their dreams — even in danger, even when death is near.”

This is who I am.
I am proud of what I did.
Proud that I defended my Master’s during the war.
Proud to have become a Palestinian researcher ✌️

Flotilla: Ok, we will sail to Palestine and directly feed Palestinians

Israel: That makes you Hamas

Flotilla: But you just said Hamas are starving Palestinians?

Sama kyk smua tmpat selain toilet kodratnya ga boleh diberakin

Klo gada tulisan smoking area ya jgn ngerokok lah. Bukan jadi dibalik, klo gaada tulisan dilarang berarti boleh.

Kalo pola pikirnya begitu, dunia isinya berak semua
