@system_monarch Netflix isn’t solving this per device—the OS,hardware, and DRM ecosystem enforce it for them. The magic piece is Widevine/FairPlay/PlayReady+hardware-backed secure video paths. Netflix sends encrypted video, and your device only decrypts it inside a secure, protected environment.

@vivoplt One super-fast worker Processes tasks quickly without waiting Redis achieves high throughput using in-memory operations, a single-threaded event loop with non-blocking I/O, and zero locking overhead.

Interviewer: Redis is single threaded, then how does it handle millions of requests per second?

@factsforupsc The H.N. Sanyal Committee is related to the law on Contempt of Courts in India. It was set up in 1961 under the chairmanship of H. N. Sanyal, then Additional Solicitor General of India, to examine the law and problems relating to contempt of court.

@EOEboh Prompt Engineering=how you ask RAG=what knowledge you fetch Fine-Tuning=how you train the brain itself Prompt engineering improves outputs without changing the model,RAG augments responses with external data, and fine-tuning modifies the model itself for domain-specific accuracy.

@EOEboh Webhooks are at-least-once delivery Your system must be: Idempotent Retry-safe If designed correctly,the provider retries failed webhooks and events are processed later;to ensure reliability,I’d use idempotency,queue-based processing,retries,& reconciliation to avoid data loss.

Your Webhook endpoint goes down for 45 minutes During that time your payment provider fires 200 events Your server comes back up What happens to those 200 events and how should you have designed for this?

@drishtiias (d)कार्बन मोनोऑक्साइड CO एक जहरीली गैस है जो फेफड़ों के माध्यम से रक्त में पहुँच जाती है और हीमोग्लोबिन से जुड़कर कार्बोक्सी‑हीमोग्लोबिन बनाती है। इससे रक्त की ऑक्सीजन वहन क्षमता कम हो जाती है,जिससे ऊतकों को पर्याप्त ऑक्सीजन नहीं मिल पाती और गंभीर स्थिति में मृत्यु भी हो सकती है।

निम्नलिखित वायु प्रदूषकों में से कौन रक्त धारा को दुष्प्रभावित कर मौत उत्पन्न कर सकता है? (a) एसबेस्टॉस धूल (b) कैडमियम (c) लेड (d) कार्बन मोनोऑक्साइड

@DailyGkzone Chandragupta II. Fa-hien, the Chinese Buddhist pilgrim, traveled to India between AD 399 and 414, a period that aligns with the reign of Chandragupta II (also known as Vikramaditya) of the Gupta Empire .

@gxjo_dev Revert = hides mistake Rewrite history = deletes mistake If the commit isn’t pushed, I’d amend it; if it’s pushed, I’d rotate the secrets immediately and rewrite Git history using filter-repo, since revert doesn’t remove sensitive data from history.

Interviewer: You accidentally committed environment variables in your last commit. What will you do? Amend or revert ?

@mysticwillz 401 → No ID card → can’t enter 403 → Valid ID, but restricted area 401 means authentication is missing or invalid, while 403 means the user is authenticated but does not have permission to access the resource.

Explain the difference between: 401 Unauthorized 403 Forbidden Same result. Access denied. Different meaning.

@EOEboh Statement 2 is false. Webhooks are indeed triggered by the source server when an event occurs, such as a user signup or payment, sending an HTTP request to your endpoint. However, if your webhook endpoint is down, the event is not permanently lost in most services

Three statements. One is false 1. Webhooks are triggered by the server when an event occurs 2. If your Webhook endpoint is down, the event is permanently lost with no way to recover it 3. Webhook payloads should be verified using a signature before processing Which one is the lie?

Interviewer: What is the difference between Fine-Tuning, RAG and Prompt Engineering? When would you choose each?

@padhai_upsc In medieval India, the term "Fanam" referred to (b) Coins The word is derived from the Tamil/Malayalam word Panam (meaning money/wealth) or the Sanskrit word Phāṇa (marked/stamped). They were typically tiny coins made of gold, silver, or copper.
