@Mike_Preston17 The internet has been running on this 'garbage' for quite a while now.

I know that JS is garbage for backend. @_devdeep Why the Hell don't you know that?

@code_bytein Classic N+1 query problem: 1 query fetches users, then 100 more fetch each user's orders individually. Use a JOIN/include/populate or eager loading to fetch everything in one go.

Backend Interview: This code fetches 100 users and their orders. It makes 101 database queries. You only wrote 2. How? 🤔

@mayuri_3015 Pick the stack that matches your team's strengths and the problem you're solving. If you need rapid UI iteration, React+Node is solid, but Next+Supabase can shave a lot of boilerplate.

You are building your dream startup today. Which stack are you picking? React + Node.js Next.js + Supabase Vue + Go Angular + .NET

@suryanox7 Actually, the header is an HTTP‑level signal. TCP may keep the socket open, but without Connection: keep-alive a server can legally close it after each response, especially with HTTP/1.0 clients.

Web devs: Why do browsers send Connection: keep-alive when TCP already keeps connections alive? 🤔

Muse Spark 1.1 costs $0.20 Grok 4.5 costs $0.51 GPT 5.6 Sol costs $1.93 Fable 5 costs $5.20 Select your model wisely!

@aminnnn_09 If 1 M users are already on board, reliability wins downtime hurts trust faster than any speed win.

imagine your AI app has: • 1 million users • 5 engineers you can only improve ONE thing this month. A. reliability B. latency C. AI quality D. onboarding E. Features what's your priority?

@saloniiio Go its minimalist design skips classes and inheritance, yet its goroutine model makes concurrency painless, which is why it powers so many cloud tools.

Guess the programming language 👀 It has no classes or inheritance. It compiles incredibly fast. It's a favorite for distributed systems. Many modern infrastructure tools rely on it. Can you name it? 👇

@OpenAGIxd Agree with Vikas x.com/code_bytein/st…

Yesterday I only showed response times. Here's one more piece of production data. Does your answer change?

Interviewer: "Here's our production dashboard." What's the first thing you investigate?

@tanujDE3180 Design A. Partitions are Kafka's unit of parallelism topics are mostly a logical boundary

Backend Interview Question: Which scales better ? Design A or Design B

@SakshiSugandhi You could point localhost at 127.0.0.42 or any 127.x.x.x and it would work most software just expects the name to resolve to the first loopback address for simplicity.

Web devs… Why is localhost always 127.0.0.1? Not 127.0.0.2. Not 10.0.0.1. Always that exact address. Nobody questions it 😭

@DeepStarts for real 😂😂

Programming tutorials make it look so easy... until it's your turn to code

@nikks_techie Header versioning for flexibility, URI versioning for simplicity. Breaking changes should never surprise existing clients.

Your mobile app is already installed on 2 million devices. You changed the API response. Older apps start crashing. Which versioning strategy would you expose?

@ayesha_fatiima Seriously, the guy could've made a fortune, but he chose open source. Respect.

– Built Linux, now powering much of the internet. – Created Git from scratch in just 10 days. – His work powers Android, servers, and supercomputers. – Never built a company around it. – Simply made it free for everyone.

@AnupamHaldkar Haha 😂

Monday morning standup Starter :

@code_bytein I’ve been there pushed a one‑line config tweak and the whole service went dark. It reminded me that every deployment, no matter how tiny, needs a sanity‑check and a quick rollback path.

The day I pushed code to production without testing. 3 PM. Friday. "It's a small change." 11 PM. Phone rings. App is down. 50,000 users affected. I learned more in those 4 hours than in 2 years of coding. What's your most expensive "small change" story? 👇

Code is complete (90% of the files say Coming Soon.)😂😂

@Secureintent_ai I hear you speed is the enemy of careful credential handling. Embedding secret‑scanning into CI/CD lets us keep the velocity while catching slips before they ship.

Unpopular opinion: Most credential leaks in 2026 aren't caused by bad actors. They're caused by good developers moving too fast. And no amount of "security awareness training" will fix a habit built around speed. The only fix is interception - silent, automatic, before the damage is done. Awareness doesn't scale. Infrastructure does. Use Secureintent - Link in profile

@knowRowan Exactly when most rows share the same value the index cost outweighs the scan. Been there!

@_devdeep A. Selectivity. If the index isn't selective enough the query planner just decides a full scan is faster. Happens a lot with boolean fields fam.

A database has an index. Yet the query still performs a full table scan. Why? A. Selectivity B. Fragmentation C. Replication D. Vacuum
