@0xPrajwal_ You have your answer in the above snapshot. AI overview and search results on Google are powered by Gemini.

@danellisona C introduced me to coding. Python helped me grasp things on my own outside of the curriculum and actually get into software dev.

@misschopra If you mean attempting to build next-gen scalable systems by prompting an AI model, without knowing anything about the concepts - yeah that was never bound to work! Feel sorry for non-tech folks thinking they could run their tech company without people who know stuff.

@solopribuilds Vibe coding (making AI write code) would still be relevant but AI slop won't be appreciated. Quality controlled code with speed and precision will prevail, rest all will die down soon. Scalable, reliable systems cannot be achieved without knowledge.

@ezSnippet Writing (Typing) code is no longer a skill like it used to be. Ofc understanding every word of AI-written code is essential but typing it manually doesn't get you anywhere now. Interesting thing would be to control AI code so that it doesn't become a vibe-coded slop.

Spent the weekend setting up MinIO on my home server so that I can use S3 features with S3-compatible APIs without paying AWS bills for my local dev.

A fantastic deep dive into 𝗦𝗰𝗮𝗹𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝘃𝘀. 𝗖𝗼𝘀𝘁, scaling trivial APIs to 𝟭𝗠 𝗥𝗣𝗦 in under 𝟮.𝟱 𝗵𝗼𝘂𝗿𝘀!

This video excels at showing vertical scaling alongside real-time cost metrics on the cloud.

3. Integration

The beauty: this dropped right on top of Gup’s existing local-first WebSocket + durable outbox architecture as SIGNAL_V1 envelopes. Transport semantics didn’t need a rewrite.

Feedback, PRs, and crypto audits welcome! 🚀

I built a local-first 1:1 chat app called Gup.
​The core idea: the relay server never stores your message history.
​Messages sit in a durable queue only until the receiver comes online. Once delivered and ACKed, the server forgets them. Your chats live purely on your device.

2. Perfect Forward Secrecy

• After handshake, every subsequent message uses the Signal Double Ratchet algorithm.
• It derives a fresh symmetric key for every single payload.
• Even if a temporary session key leaks, past and future messages remain completely secure.

@AmanGodflame @shivambhadani_ That's not how it works. Manager's tactics mean a lot. Players can't just gang up and play as they like. These ideas don't work in real life.

[Kartikey Hebbar @HebbarSahab]

@rj_nationalist @SumitM_X Judgement skills on what? When the candidate doesn't know the theory, nor system design or architecture, then there is no point in vibe coding with AI. Nowadays, everyone thinks they are engineers with these AI tools but only a small number of people know their shit.

[Kartikey Hebbar @HebbarSahab]

@rnescalz @arpit_bhayani @peculiarvivek Did you say things like understanding Redis internals matter less after AI?

[Kartikey Hebbar @HebbarSahab]

@arpit_bhayani I feel learning by doing helps a lot. What would be the best way to practice distributed systems in action especially when you don't come across all the topics at work?

[Kartikey Hebbar @HebbarSahab]

@Crickeddicted @striver_79 Surely you haven't worked on production level code yet let alone working with AI tools in production. You'll learn as and when you do.
