Hello Techies!

🚀 New Video Alert!

How do large-scale systems generate unique IDs without collisions?

In this video, I break down 5 real-world ID generation strategies used in distributed systems:

Auto-increment DB IDs

UUID / GUID

Snowflake-style time-based IDs

Zookeeper / etcd distributed counters

Hybrid ID generators (used by Instagram, Firebase, fintech systems)

If you’re preparing for system design interviews or building high-scale backend systems, this one is a must-watch.

Hello Techies!

🚨 New Video Alert! 🚨
If you’re building or learning distributed systems, you must understand why system clocks can’t be trusted — even with NTP or Chrony syncing them.

⏱️ In my latest video, I break down:
• Why timestamps go wrong across machines
• How tiny millisecond skews break ordering
• Logical clocks (Lamport, Vector) explained simply
• Java + Python demos you can try yourself
• Practical tips to fix misordered logs and event flow

If you’ve ever wondered “Why did this event happen before that one… according to the logs?” — this video is for you.
