Be honest, how do you handle your version control? 🛠️
Option A: The terminal purist (git add ., git commit -m, git push)
Option B: The GUI user (VS Code Git extension, GitKraken, GitHub Desktop)
Using the terminal forces you to actually understand what is happening under the hood (detached HEAD, merge conflicts, rebasing). GUIs are faster for visual staging, but you are helpless when a real merge conflict breaks the branch.
If you can't fix a broken repository using raw terminal commands, you don't fully know Git.
Are you team CLI or team GUI for your daily dev workflow? 👇
Interviewer:
If databases can already store millions of records, then why do companies like Uber, Netflix, and LinkedIn still heavily rely on Kafka?
What’s the actual problem that databases alone can’t solve here?
6 hours of non-stop backend coding will destroy your back and posture if you aren't careful. 💻❌
My daily non-negotiable rule to fix this:
Every 2 hours of screen time = a quick circuit of pull-ups, push-ups, and deep squats.
Your physical engineering directly impacts your software engineering. If the body is sluggish, the code will be sloppy.
What is your number one rule for staying fit during a heavy coding grind? 👇
Most backend developers use Java Threads daily without realizing how expensive they are to the CPU. 🖥️
By default, Java uses platform threads which map 1:1 to OS-level threads. Each platform thread consumes around 1MB of memory just for its stack.
If your backend receives 5,000 concurrent requests, that's nearly 5GB of RAM gone just for thread management—leading to frequent context switching and latency.
This is why Virtual Threads (introduced natively in Java 21) are a complete game-changer. 🚀
Virtual threads are lightweight, managed by the JVM rather than the OS, and consume only a few kilobytes. You can easily spawn 100,000+ virtual threads on a normal machine without breaking a sweat.
If you are building modern high-throughput Java applications, stop relying on traditional heavy thread pools. Switch to:
Executors.newVirtualThreadPerTaskExecutor()
Are you still using traditional thread pools or have you migrated your enterprise backends to Virtual Threads? 👇
