Open a website on your laptop. Now open the same website on your mobile phone. Does it look the same? Probably not. The menu may change. Images may become smaller. Columns may turn into a single layout. Buttons may also move to different positions. This happens because websites need to work on different screen sizes. Today,...

Imagine building a login page for a website. You enter the correct username and password. Then, you click the login button. Everything works perfectly. However, what happens when someone enters the wrong password? What if the database stops working? Could a recent code change break an older feature? These situations explain why writing code is not...

Imagine spending several weeks developing a website. The design looks good, every button works, and all the features pass your tests. You are finally ready to show it to the world. But there is one problem. The website is still running only on your computer. How will other people access it? Where will the application run?...

Imagine building an application that stores thousands of customer records. A user searches for one customer, but the application takes several seconds to find the information. The software works, yet the experience feels frustrating. Now imagine the same application finding the record almost instantly. What creates this difference? One important factor is how the application organises...

Have you ever visited a website, selected dark mode, and noticed that the same setting remained active when you returned? Or added products to a shopping cart and found them waiting when you opened the website again? These experiences are possible because websites can store information in the browser. This concept is known as browser storage....

Two applications can perform the same task but feel completely different to users. One may respond immediately. Another may take several seconds to load. One website may feel smooth when scrolling. Another may freeze or respond slowly. Both applications may technically work. So, what creates the difference? The answer often comes down to software performance. For...

Finding code online has become a normal part of software development. IT students often use GitHub repositories, packages, libraries, tutorials, and open-source projects to learn or solve problems faster. However, there is one important question that often gets ignored: Can you legally use this code? This is where software licensing becomes important. A piece of code...

Software can look modern, load quickly, and work perfectly for one person. However, that does not mean it works well for everyone. A user may depend on a keyboard instead of a mouse. Another person may use a screen reader. Someone else may need larger text or stronger colour contrast. These users should not have to...

A student has an assignment due tomorrow. The code almost works. One small part is causing an error. Instead of finding the real cause, the student adds a quick workaround. The application works again. Problem solved. Or is it? A few weeks later, another feature depends on the same code. The old workaround causes another problem....

A student builds a website. The buttons work. The form submits. The database stores the information. Technically, everything seems fine. Then someone uses the website for the first time and asks: “Where am I supposed to click?” That simple question can reveal a problem that code testing may not find. Software is created for people. Therefore,...
