Bare Metal vs VMs vs Containers: Common Myths Busted

You’ve just spent $40,000 on server infrastructure and your CTO is second-guessing every choice. “Shouldn’t we be using containers instead of VMs?” they ask, scrolling through yet another Medium article on their phone. Sound familiar? The bare metal vs VMs vs containers debate has turned into tech’s favorite holy war, with surprisingly little actual data […]
Mastering Consistent Hashing: A Must-Know Algorithm for Scalable Systems

Ever woken up to frantic alerts because your database can’t handle the load after an unexpected traffic spike? That familiar panic in your stomach isn’t just you – it’s the collective trauma of engineers everywhere whose systems weren’t built to scale. Consistent hashing isn’t just another algorithm you can ignore. It’s the difference between your […]
LSM Trees Explained: The Backbone of High-Performance NoSQL Databases

Ever watched a database melt down when hit with too many writes? I have, and it’s not pretty. You’d think modern systems would handle massive data streams without breaking a sweat, but traditional B-trees start wheezing like they’re running a marathon in flip-flops. That’s where LSM Trees come in. They’re the unsung heroes powering the […]
Bloom Filters Demystified: Space-Efficient Lookups with Real-World Examples

Ever spent hours optimizing a database query only to watch your application crawl to a halt with a million records? That frustration you’re feeling right now? That’s exactly why Bloom filters exist. These probabilistic data structures might sound like something from a computer science textbook, but they’re quietly powering the technology you use daily – […]
Back-of-the-Envelope Estimation for System Design: A Guide to Capacity Planning

Ever had a system crash during peak traffic and you’re scrambling to explain why your capacity planning missed the mark? You’re not alone. Most engineers I’ve worked with can build amazing systems but freeze when asked “will this handle Black Friday traffic?” Back-of-the-envelope estimation isn’t just some theoretical exercise—it’s your first line of defense against […]
Understanding SSL, TLS, and HTTPS: How Secure Web Connections Work

Ever clicked that little padlock icon next to a website URL and wondered what magic keeps your credit card details from being stolen? You’re not alone. Millions of people shop, bank, and share personal information online daily without understanding how their data stays protected. This isn’t just tech jargon—it’s the invisible shield between your sensitive […]
What is the OSI Model? Explained with Real-World Examples

Ever tried explaining to your grandmother why her Netflix isn’t working? It’s somewhere between “the internet is down” and a 20-minute lecture on TCP/IP protocols that makes her eyes glaze over. That’s exactly why the OSI Model matters to anyone working in tech. The OSI Model is like the anatomy chart of computer networking—break it […]
Debugging Like a Pro: Techniques Every Developer Should Know

Ever spent three hours chasing a bug only to discover it was a missing semicolon? You’re not alone—the average developer spends 75% of their coding time debugging rather than building. Let’s change that. This guide will transform your debugging from chaotic hair-pulling to methodical problem-solving that actually feels satisfying. Debugging like a pro isn’t about […]
Demystifying Cloud Native: Everything You Need to Know

Did your last “cloud transformation” project feel like trying to build a spaceship with an IKEA manual? You’re not alone. Nearly 78% of IT leaders report their cloud initiatives stalled or failed completely in the last two years. Cloud native isn’t just another tech buzzword to ignore. It’s an entirely different approach to building and […]
Mastering Cache Systems: The Key to Building High-Performance Applications

Ever hit refresh on an app and waited 12 seconds for it to load? That’s 11 seconds too many in a world where users abandon ship after just 3. Behind every lightning-fast application, there’s a well-designed cache system quietly making magic happen. I’m about to show you exactly how to master cache systems to build […]
