Unhang Windows PC

26 May 2025

I often found that Ctrl+Alt+Delete unhangs the Windows PC. I googled why?

The nutshell answer is : Ctrl+Alt+Delete is a secure attention sequence (SAS) triggers a system interrupt, effectively forcing the computer to respond. This is directly handled by the Windows operating system kernel. That means it can bypass most of the stuff that’s currently running (including frozen apps or even some parts of the graphical interface).

Cool to know this.

Google AI Overview

18 May 2025

I don’t search for things as much as I used to. These days, I just go straight to ChatGPT. I don’t feel like Googling and clicking through multiple pages to find the best answer. I ask ChatGPT, and most of the time, the results are satisfying.

I’ve heard that traditional Google searches are declining. But now, they’ve introduced AI Overviews at the top of their results. I think it’s a good idea—because we get a quick summary of what we’re looking for, along with links to other websites. Yes, I think it’s a good move.

Sticky footers

11 May 2025

To make a sticky footer in the Bootstrap you can use the below.

<body class="d-flex flex-column min-vh-100">
  <main class="flex-fill">
    <!-- Your page content here -->
  </main>

  <footer class="bg-dark text-white text-center py-2">
    <!-- Your footer content here -->
  </footer>
</body>
  • d-flex flex-column min-vh-100 on : makes the body fill the viewport and act like a vertical Flexbox container.
  • flex-fill on : makes the content area take up all available vertical space, pushing the footer down.
  • footer: stays at the bottom even with short content.

Modernization of Apps

9 May 2025

One of the main topics discussed in the seminar I attended was modernizing legacy applications.

Legacy applications are typically monolithic in nature, making it difficult to scale or integrate new features quickly. The monolithic apps ruled the software industry for a very longer time, but now people are moving (already many moved) to its great alternative, the microservice architecture.

I’ve come across monolithic applications that are tightly coupled with environments like Oracle or .NET, where growth can become a painful process. Over time, these systems tend to become slow, expensive to maintain, and resistant to change.
