Tech, AI, engineering — and life as it actually is. Building in the industry, talking about the world around it.

[Nitish kumar @knitish899]

They used to say "upskill yourself" and you'd be safe.

Now you upskill... and by the time you're done, you're not competing with the next guy. You're competing with AI.

Every single minute something new drops. A new model, a new tool, a new "this changes everything" post.

You don't even get time to master one thing before it's outdated.

It's not a skill race anymore. It's a survival race against something that doesn't sleep, doesn't get tired, and doesn't need a salary.

Nobody tells you that part.

[Nitish kumar @knitish899]

Growing up, “success” meant a stable job, a house, a routine.
Now even that feels unstable — because the machine learning your job might also be learning your life.
Funny how progress feels a lot like anxiety these days.

[Nitish kumar @knitish899]

Every industry says "adapt or die."

Nobody tells you the ones saying it already have a backup plan — and you don't.

[Nitish kumar @knitish899]

@edinsoncode Facts. If it takes a weekend to clone, it was never a product — it was a demo with a payment gateway attached.

Real moat isn't the code. It's distribution, trust, and the problem actually being solved end-to-end. AI made building trivial. It made nothing else easier.

[Nitish kumar @knitish899]

6 years in this industry. Never felt this anxious.

Every founder is out here saying "in 5 years there'll be no IT jobs."

Bro there's no job TODAY. Not in 5 years.

Companies are laying off people with zero valid reason. Service companies have no projects, no pipeline, nothing in the queue.

Everyone's "shipping" a new product daily on X. Reality — 0.01% of that actually makes money.

Freelance clients who used to pay $100k are now paying $10k for the same work. Because "AI can do it now." (It can't. Not really. But try telling that to a client.)

4 years back, during COVID, this industry was the golden ticket. Everyone wanted in.

Now it feels like — don't come here. And if you're already in it, build yourself a backup option. Because this industry isn't going to save you.

[Nitish kumar @knitish899]

Everyone posting "I made $10k using Claude, here's how 🧵"

Meanwhile the actual people building with Claude are just... quietly shipping. No thread. No course. No "link in bio."

The loudest AI money post is inversely proportional to the money actually being made.

@edinsoncode @viaintisol Full stack developer

[Nitish kumar @knitish899]

Still awaiting any resolution for this absurdly inflated bill. Furthermore, this month's bill has added another ₹1,000, bringing the total outstanding to ₹97,500—a massive spike compared to my usual historical bills of ₹100–₹200.
Smart meter baseline issues remain unaddressed. Please investigate and correct this immediately. @JbvnlQ @ESE_Gumla @md_jbvnl #JBVNL

[Nitish kumar @knitish899]

My electricity bill shows ₹96,839 for ONE month — clearly wrong. Smart meter’s old-reading baseline was 13706 KWH but bill doesn’t reflect it. Consumer No. 2710, Bill No. 260611235925234 (Basia, Gumla). Please fix urgently.@JbvnlQ @ESE_Gumla @md_jbvnl #JBVNL

With over six years of experience in software engineering, including two years dedicated to production-grade Generative AI systems, I would be honoured to contribute my expertise toward AI awareness and best-practice adoption within government departments and allied sectors in Jharkhand.

Curious dev here 👋 Been building GenAI/full-stack systems (Claude, RAG, Node, Next.js) for 6+ yrs. Noticed a lot of Jharkhand govt portals could use a UX + security refresh. Would genuinely love to volunteer/consult on making citizen services faster & more reliable. 🇮🇳

@JioCare I got a call saying it will be resolved but still there is no info or installation happened

[Nitish kumar @knitish899]

Hey @jio_fiber @JioCare @reliancejio
I have booked jio fiber installation and paid all the amounts required for booking on 1 July 2026 .my order number is NO0001EC4HD6

I have been told by technician that it will be installed in next 24-48 hours but no one has come yet to install when I call the concern technician he was just telling coming in 15 mins but never comes

This is so frustrating that even after paying the booking amount there is no proper support and service being delivered.

You are spoiling your reputation

They say if you want to really understand how something works, you should build it yourself. 🛠️

So, I decided to build a database from scratch.

Today, I'm thrilled to open-source **LumeDB** — a high-performance NoSQL document database written entirely in Rust! 🦀

This project pushed me to dive deep into complex database architecture concepts, including:

• 🌲 LSM-Tree Storage Engine — Designed for high write throughput and efficient storage  
• ⚖️ MVCC Transaction Manager — Ensuring full ACID compliance  
• 🚀 Performance Optimization — Faster reads using Bloom filters and LZ4 compression  

✨ Key Features:
• Interactive CLI  
• Robust Query DSL  
• Secondary B-Tree Indexes  

Building LumeDB has been an incredible engineering journey — from low-level storage design to high-level query execution.

🔗 Check out the project, run a few queries, and share your feedback!

Whether you're a developer, researcher, or business leader — Opus 4.8 will change how you work.

The future of AI isn't coming. 𝗜𝘁'𝘀 𝗵𝗲𝗿𝗲. 🔥
