A quick way to learn the system type, kernel version, and hardware architecture—information that shapes my next moves. But many only know the -a “all-in-one” flag. Let’s dig deeper into what uname can really do. What Does uname Actually Do? uname calls the uname() system call, fetching information directly from the kernel. https://jsokit.com/blog/posts/http-response-headers-analysis-a-complete-guide-to-security-scoring-and-performance-optimization/ Wed, 18 Feb 2026 18:46:16 +0000 https://jsokit.com/blog/posts/http-response-headers-analysis-a-complete-guide-to-security-scoring-and-performance-optimization/ HTTP Response Headers Analysis: A Complete Guide to Security Scoring and Performance Optimization Recently, while debugging a production issue, I noticed our API responses were painfully slow. Opening DevTools revealed the culprit: Cache-Control headers were completely missing. Every request fetched resources fresh from the server. This got me thinking—HTTP response headers are the “invisible configuration” that’s often overlooked, yet they have a massive impact on both security and performance. So I built a tool to automatically analyze response headers, and along the way, documented everything I learned.
