People assume open source means writing 5,000 lines of complex C code. My first accepted patch was simply fixing a documentation ambiguity in the eBPF networking subsystem and adding a test case. The review process taught me more about professional Git hygiene and code standards than any college lecture.

Concatenating user input directly into SQL strings (`'SELECT * FROM users WHERE name = '' + input + '''`) allows input like `' OR '1'='1` to bypass all authentication. Prepared statements separate query bytecode compilation from parameter data values, making injection physically impossible at the database driver level.

Section 52 of the Copyright Act allows fair dealing for private or personal use, including research, criticism, review, and reporting. If you are building educational tools or research datasets, citing sources properly and not commercializing copyrighted materials directly keeps you on solid legal ground.

Setting `resources.requests.memory` tells the kube-scheduler where to place the pod based on guaranteed capacity. Setting `resources.limits.memory` is a hard ceiling: if your Node/Go process exceeds it, the Linux kernel invokes the OOMKiller and terminates the container with exit code 137. Always set memory limits to prevent memory leaks from starving neighbouring pods on the worker node.

I can’t take it anymore. People outside think NIT Warangal is a top-3, Tier-1 institute, but living here is an absolute nightmare. 1. Basic Infrastructure Failures (No tables, no chairs, broken toilets) No Basic Amenities: We haven't even been provided basic study tables and chairs in our hostel rooms. How is a student supposed to study or sit comfortably in their own room? Sanitation Crisis: The hostel toilets are biohazards. Flushes don't work, jet sprays are completely broken, a

CTFs are divided into 5 standard categories: Web, Crypto, Forensics, Rev (Reverse Engineering), and Pwn (Binary Exploitation). Start with PicoCTF: solve the 50-point web challenges (inspecting page source, modifying cookies, basic SQL injections), then learn Ghidra for reverse engineering simple binaries. The dopamine of finding your first flag is unmatched.

ZKPs let you prove you know a secret without revealing the secret itself. Imagine a circular cave with two paths (A and B) separated by a locked door in the middle. If Bob watches Alice enter through random paths and always emerge from whichever path he shouts, after 30 trials Bob is mathematically certain Alice has the key, even though Alice never showed him the key. The future of privacy-preserving scaling.

Classic computer architecture experiment: Iterate over 100,000 integers and conditionally sum elements > 128. If the array is unsorted, the CPU's branch predictor misses 50% of the time, stalling the instruction pipeline. If the array is sorted, branch prediction accuracy is ~99%, and execution runs 6x faster. Understanding hardware mechanics makes you a dramatically better programmer.
