Jev got outdated so fast, just like my knowledge of what’s the latest LLM 💀

[Mrinal Manna @mrinal_mann]

Trying Jev, a model built for classification, not text generation.

Interesting use cases:
→ Spam detection
→ Game-state decisions
→ Tech-stack selection
LLM for generation.
Classifier for decisions.
Why force an LLM to generate JSON for a simple decision?

Found an epic video on scaling today.

Going from a simple Node.js API to 1M+ requests/sec and seeing the bottlenecks move from CPU → network → DB → Redis was crazy.

The biggest takeaway: scale smarter, not just bigger.

Found a gem 💎

What stood out wasn't the code, but how senior engineers think before building.

Problem → trade-offs → failure cases → then code.

Good engineering starts before the first line of code.

Just saw @perplexity_ai launch Comet — it’s not a browser, it’s a second brain 🧠

Think out loud, ask questions anywhere, and let AI handle the rest.
Browsing will never be the same.

just finished designing the system for a project i’ve been brewing for weeks.

if you’re a student who’s ever felt lost — no roadmap, just chaos — this might be for you.

mvp coming soon.
hoping this genuinely helps.

🧠 System Design for freshers is becoming the new normal.

Came across tons of interview reviews lately — LLD, chat apps, scalable APIs… all being asked at entry level.

Thinking in systems isn’t just for seniors anymore. The bar is rising fast.

From “Bruh, what even is a binary tree?” 🌳
To “DP? Just give me the state and I’ll slay.” 😎

@JorgeMenaDev Sure 😃

[Mrinal Manna @mrinal_mann]

Many tier-3 colleges lack a proper app for notes or notices. Students rely on Telegram or PDFs.
So I’m building an app where students can access semester-wise notes & updates—simple, clean, and built for real needs. Thoughts?👇
