Choosing the right DB in System Design? 🛑
Match your access patterns:
•SQL: ACID, complex joins, relational data.
•NoSQL: High throughput, horizontal scale, flexible schema.

Right tool = right scale. ⚙️📉

Prompt engineering isn't dead—it just got promoted. We've moved from clever words to building code harnesses.
Model quality matters, but the harness wins. 🤖⚙️ #AI #SoftwareEngineering

Idea watch: INFY at an 11 P/E entry? 📊
Hypothetical setup: Sell the Oct '26 900 PE.
•If it drops below 900: Accumulate 400 qty at a deep discount.
•If it stays above: ~6% yield on ₹45K margin.

ESDS Software hyped a high-flying growth narrative for its IPO, only to drop a staggering 57% sequential net profit collapse right out of the gate. When pre-IPO projections don't match execution, retail investors get trapped at lower circuit. ⚠️ #ESDS #IPO #StockMarket #Investing

@awscloud 2 million docs a day changes the math completely. The real takeaway from the thread isn’t just hitting 99% accuracy—it’s maintaining that throughput without blowing up the compliance audit trail.
How are you handling edge cases when unstructured layouts shift? 📉

Google, OpenAI & Anthropic are forming an AI safety body by 2026. Critics call it a 'cartel' to stop open-source rivals & dodge regulation. #AISafety #BigTech

OpenAI releases GPT5.6 Sol - complex coding, GPT5.6 Luna - high volume tasks and Anthropic releases Opus 5.5.

Both these releases are said to be drastically reducing the token costs and to be cheaper.

@laozhang_ai The biggest end-to-end efficiency gains come from multi-step, autonomous agentic workflows (like OpenAI's Sol/Luna programmatic tool calling and Anthropic's Opus 5.5 multi-file code execution). They complete long-horizon tasks in fewer steps, slashing total running costs.

Varsity & trading desks love AI plug-ins, but rogue LLM APIs are wide open.
If your architecture trusts default vendor security, you're exposed.
