Building things to understand how they work

A new cybersecurity investigation reveals LG Smart TVs are quietly spying on living rooms: recording audio even when screens look off, tracking nearby phones on your home Wi-Fi, and cataloging everything on-screen for ad brokers. Security researchers urge owners to disconnect them from the internet immediately

I have written an article about complete backend how things are connected, stored, processed. Check it out

Most backend engineers know the terms.

But do you really understand how they connect?

Code → Memory → CPU → OS → Concurrency → I/O → Networking → Storage → Databases → Distributed Systems → Reliability → Performance. https://t.co/1gbMC8i7RU

3 API mistakes that can seriously hurt your production system:

1. Skipping Authentication & Authorization
2. Not using Pagination for large datasets
3. Exposing detailed backend errors to clients

They look like small implementation decisions.

But they can turn into:
→ Data leaks
→ Performance issues
→ Security vulnerabilities

Fix these before you ship, not after production breaks.

Save this for your next API review. 🔐

Everyone is talking about GPT-6 Astra’s 99.9% score, but here is the precise context.
ARC Prize ran and published both evaluations. Astra scored 62.7% with the Standard harness at max reasoning, costing $26,098. It scored 99.9% with the Provider Adapter at high reasoning, costing $18,817. The Adapter preserves reasoning between calls, so the difference came from how context was carried forward, not who ran the test.
Claude Opus 5 scored 30.2% at high reasoning with the Standard harness. Therefore, 62.7% versus 30.2% uses the same harness, but different reasoning settings.
More importantly, ARC-AGI-3 tests whether AI can explore a completely new game, learn its rules and complete the goal. It doesn’t prove AGI is here, but it shows how quickly AI is improving.
Don’t wait for AGI. Start using AI for one repeated task today.

@chesscom Wrong, all legal chess positions are ~40 oom less than the estimated atoms in the Universe. And ASI will figure out ways to solve and compress that are far beyond what we could possibly comprehend.

(Here I am arguing with some random intern at a chess website 🤦‍♂️)

Tired of burning tokens on AI coding? GitHub just broke down why blindly shortening outputs actually drives costs up, showing that real savings come from cleaning up hidden junk like build logs and eliminating repeat retrieval steps

What if we build a lightweight, open-source Google Authenticator in Rust from scratch, who'd use the CLI?

[Vansh soni @_VanshSoni_]

@shydev69 That’s what it’s like 5 min of topology creation

[Vansh soni @_VanshSoni_]

@Arnav_Upadhyay7 It’s easy u just have to give ip addresses, gateway route, routing policy and acl if needed isn’t it like less than 10 min of topology?

[Vansh soni @_VanshSoni_]

How does Google Authenticator work with zero internet?
- Most people think it receives a code over the network. It doesn't.

Think of it as a pure function:
⁠f(secret_key, current_time // 30s) -> 6-digit code
1. Setup: Scanning the QR code shares a static ⁠secret_key⁠ between your phone and the server.
2. Clock: Every 30 seconds, both generate the same time block: ⁠floor(unix_time / 30)⁠.
3. Compute: Both run an HMAC hash on that block using the key, and slice out 6 digits.

-Since both have the same secret and the same clock, they get the exact same answer independently. No Wi-Fi required.
