@Priyansh_31Dec @striver_79 @ankushdharkar Got it. Actually wanted to try cp but seeing market condition and not being from tier 1, Idk whether spending so much effort on it will be worth it or not. But yeah got ur point.

Hey @striver_79 @Priyansh_31Dec @ankushdharkar if someone is already from graduated from tier 3 clg, and never done cp, should he stick to leetcode and dev, or start cp for a better switch. Considering he has more than 1 year to prepare.

Before jumping into books like DDIA or Database Internals, it helps to understand the systems layer these designs are built on. A lot of the design of such data-intensive systems is based on virtual memory: page tables, page faults, mmap, the page cache, swapping, NUMA placement, TLBs, and the tradeoffs between what the OS wants and what the database wants. My latest article is a ~25,000-word mini-book on virtual memory. It starts from first principles and goes all the way down to advanced topics like NUMA placement and performance debugging with tools like perf and /proc. I also wrote it differently: as a dialogue between a user-space process and the kernel. Most treatments of virtual memory are dry and fact-heavy. I wanted this one to feel more like a story, while still being technically deep. Link below.

I should start competitive programing now after graduation. Feels pretty stupid but I think it's better than grinding leetcode.

Leetcode is the worst platform to learn problem solving because it doesn't have a hierarchical structure and complexity. U get bunch of random problems that uses different concepts. Easy, medium, hard can't categorise all the questions difficulty. That's why cp is much better
