Z-Index computed as auto even though it is set with a value on Chrome

This is a little known fact about z-index and usually missed. If you read the article on w3schools then also you might miss this. It says:

Note: z-index only works on positioned elements (position:absolute, position:relative, or position:fixed).

What this essentially mean that the element on which you are applying z-index, you need to have position attribute specified on it. Ideally use one of the above position values. If position attribute in the css style is not set z-index would be computed as auto. Google Chrome is quiet strict about this. Use a syntax like below.

img {
position: relative;
z-index: 100;
}

Thats the reason, why many times we don't see z-index working on out elements.

Why India Hasn’t Built Its GPT Moment (Yet)

No Amazon-style platform. Why? Innovation Isn’t Accidental—It’s Engineered The Zerodha Daily Brief recently asked why India hasn’t built a global product company like Apple. The key argument: India isn’t building for the world. It’s solving for local constraints, scale, and affordability—but global scale requires deep IP, design, and tech differentiation. It’s not just about software, it’s about systems thinking. More importantly, it answers the question: Why do countries innovate? The answer isn’t just genius or ambition—it’s incentives and ecosystems. The U.S. Defense Department, for example, accounted for nearly 70% of federal R&D funding during the Cold War. China has pumped billions into semiconductors and AI with long-term national alignment. These aren’t short-term bets—they are strategic, delibe...

Problems with mysql.sock

Sometimes while working on Linux, mysql.sock may get deleted by mistake due to some softwares.. in such cases any access to mysql wont be possible as the sock file defines the socket connection for mysql. It will give an error of the following type: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) In such cases follow these steps to reconfigure mysql: Delete the log files with the names: ib_logfile0, ib_logfile1 and ibdata1 in the /var/lib/mysql directory Then type: "mysqld_safe --user=mysql &" This will automatically create mysql.sock file and even the new logs files. This is a very simple solution which I used recently and decided to share with you people.
