@shub0414 Great share subh

html ↓ css ↓ javascript ↓ git & github ↓ react ↓ node.js ↓ express ↓ mongodb ↓ rest apis ↓ authentication (jwt / oauth) ↓ typescript ↓ next.js ↓ docker ↓ ci/cd congrats you are a full-stack developer now

As a developer, Have you ever wondered : You type just "how to" in Google search and it instantly shows full suggestions like "how to make money", "how to cook pasta" etc... There are 8.5+ billion searches globally every day. How is this autocomplete so fast?

@0xlelouch_ Throughput is limited by partition parallelism. Adding consumers beyond partition count doesn’t help. Also check processing latency per message could be the real bottleneck.

Your Kafka consumer is processing messages very slowly. Increasing consumer count from 3 to 10 doesn't help. Why not and what's the bottleneck?

@SumitM_X I’d rebase. Keeps history clean and avoids a messy merge commit. But only if the branch isn’t shared otherwise, merge to avoid rewriting history.

Your feature branch has 50 commits. Main has moved ahead with 300 commits. What will you do: Rebase your branch or merge main into your branch?

@ChillxxLife You got this buddy and also add caching too.

@devXritesh Trie data structure 🤧 Last topic of DSA 💀🤧

@thekevinqi DS using trie + edge cache for faster lookups and result serving

@devXritesh Caching

@Itstheanurag Totally agree! Diversifying from field experts > one creator grind. Unemployed dev wisdom hits different .

See i believe if you want to learn something learn from the experts in that field. Learning about databases from ezsnippet would be stupid if Hussain nasser and arpit bhayani exist. Learning DSA from code with Harry would be stupid if kunal's videos exists. Learning rust from technical thapa would be stupid if let's get rusty exists. The point is stop working one guy, everyone on YouTube has something they are best known for. By not following them all you are hindering your progress. You are learning things from the top layer only but never from the core of it. Thanks for this matter, an unemployed dev and not the president of United States.

@Inosukeei_coder In searching Trie ruling, I have also used in my work.

@devXritesh It means DSA handles main role.

@0xPrajwal_ I have prepared yesterday and yeah it's coincidence 😅

@devXritesh Bro what a coincidence 😂 I posted similar

@DINESHVERM578 Glad you liked buddy, more such stuff coming soon

@devXritesh Great share 💪

@0xPrajwal_ Using DS and caching to serve data faster. Trie + Edge Cache.

Interviewer :- If Google shows results in milliseconds, how does it search the whole internet so quickly?

@Devinbuild So it's part of claude now?

Claude after realizing OpenClaw has been dominating

@droidbuilds I have started at 18 bro

Be honest , what age did you start coding? I started at 19 😅

@nia_thinks Vibe coding changes game, just need faster development and deployment.

Before vibe coding: – 6 months to ship – $30K spent on developers – 3 pivots before launch – still not done After vibe coding: – idea on Monday – live on Friday – real users by the weekend the speed changes everything.

@ravikiran_dev7 It's best and simple way. Early founder don't need bigger team

The solo founder stack (2026): Claude: $20/mo Supabase: $0 Vercel: $0 Stripe: 2.9% + 30¢ per transaction GitHub: $0 Domain (.com): $12/yr Cloudflare: $0 Total fixed cost: under $25/mo You don't need VC money. Just Ship it.

@thekevinqi Congrats on the redesign launch and getting to that inflection point, Kevin! Love seeing the persistence pay off after the rough early days.

We've burned $75K of our money building this. 🔥 For a long time, it looked like a terrible idea. Now we’re finally close to an inflection point. My name is Kevin Qi, and this is the story of Festa: In early 2024, my cofounder asked me what I wanted to do with the rest of my 20s. I had a great career at Amazon, but deep down I knew I had always wanted to build something of my own. I started coding as a kid just to build things, launched websites that got real users, and even tried starting a company at 17. It failed. But that was the point. So we started meeting weekly, throwing around ideas. Factory Automation. ERP AI. Hardware. Eventually we landed on something crazy: What if AI could coordinate live events in real time? I built the first version during nights and weekends. We tested it at our own event in SF. It worked. More importantly, people instantly “got it.” That was enough conviction for me. I quit Amazon. Then reality hit: • YC rejection • failed marketing • $2K in ads → 0 customers • first wedding sale: $130 We even fumbled a $1K+ deal after messing up pricing. But we kept going. We rebuilt the product and shifted entirely to content + UGC. Over the last 6 months: • hundreds of videos tested • figured out what actually converts • acquisition cost now down to ~$7 • and finally approaching potential repeatable profitability Which brings us to today. We just launched the biggest redesign of Festa yet and for the first time, anyone can try it instantly as a guest to a "fake investor and startup conference event”.

@joncphillips Haha, classic startup energy nothing like finding a mystery content library right after you think everything's deployed and safe. "This is fine" dog vibes on point. How big was this hidden library?

Discovering a content library nobody mentioned 3 hours after a migration and a prod deployment 🤯

@droidbuilds @grok

@devXritesh @grok how

@TreeApostle The autocomplete magic? Precomputed tries + heavy edge caching, ranked by popularity, trends, and your own history. Near-zero latency engineering at planetary scale. What's the wildest autocomplete suggestion you've ever seen pop up?

@devXritesh Precomputation and edge caching using a trie its near zero latency. a trie helps with prefix matching but ranking what shows up uses popularity, trending and your search history
