NSP.Mathi — Sat, 24 Aug 2024 09:41:53 +0000

User experience (UX) is all around us, embedded in every product and service we interact with, both digitally and physically. The quality of these experiences can significantly impact our satisfaction, efficiency, and even our emotions. In this blog post, I’ll share 10 of the best and 10 of the worst user experiences I’ve encountered in my daily life, along with the reasons and justifications for each.

10 Best User Experiences:

I. Google Search:

Justification: The ease of use and spill-resistant design make it perfect for workouts, travel, and everyday use.

VIII - Adjustable Car Seat:

Why: A car seat with multiple adjustments for height, recline, and lumbar support allows drivers to find their optimal driving position, reducing fatigue on long trips.
Justification: The ability to tailor the seat position to individual needs enhances comfort and safety.

Justification: The customization options and comfort enhance productivity and overall well-being.

10 Worst User Experiences:

I - Instagram: On Instagram, one of the most frustrating aspects is the inability to edit comments after posting them. Additionally, shared links in the comment section appear as plain text, not as clickable hyperlinks, which further detracts from the user experience.

II - The Ketchup Bottle: A common issue with ketchup bottles is the difficulty in squeezing them, requiring excessive force to dispense the ketchup.

III - Hard-to-Open Packaging:

Why: Packaging that is difficult to open, such as tightly sealed plastic containers or blister packs, can cause frustration and even injury.
Justification: Poor packaging design can negatively impact the overall product experience, leading to user dissatisfaction.

IV - Inconsistent UI Across Mobile Apps:

Why: Inconsistent user interfaces across different apps from the same provider can create confusion and hinder usability.
Justification: A lack of uniformity in design and navigation increases the learning curve and reduces user confidence in the app.

V - Slow and Unreliable Wi-Fi Connections:

Why: Slow Wi-Fi speeds and frequent disconnections can disrupt work, entertainment, and communication.
Justification: Unreliable connectivity can lead to frustration, particularly in situations where stable internet access is essential.

VI - Clunky Online Forms:

Why: Online forms that are too long, poorly designed, or require unnecessary information can be tedious and frustrating to complete.
Justification: Inefficient forms can lead to higher abandonment rates and a negative perception of the service or website online.

I was felt this for job application most in Government sites like HAL, BELL, DRDO, India Post etc,.

I was felt this form some chips and biscuits products.

VIII - Social Media App Notifications:

Why: Social media apps often send excessive notifications, which can be overwhelming and lead to notification fatigue.
Justification: The constant barrage of alerts can cause users to feel stressed and distracted, negatively impacting their experience

IX - Overly Intrusive Pop-Up Ads:

Why: Pop-up ads that interrupt browsing experiences can be intrusive and annoying, especially when they are difficult to close or contain misleading information.

I was felt this in Video downloader sites and Online Chess.com game other random sites.

X - Automated Customer Service Systems:

Why: Automated phone systems often lead to frustration due to long wait times, unclear options, and difficulty reaching a human representative.

Data Visualization D3.js

NSP.Mathi — Wed, 03 Jan 2024 04:39:51 +0000

Data is all around us, but it doesn't mean much without shape or context.

In the Data Visualization Certification, you'll build charts, graphs, and maps to present different types of data with the D3.js library.

You'll also learn about JSON (JavaScript Object Notation), and how to work with data online using an API (Application Programming Interface).

Data Visualization with D3
D3, or D3.js, stands for Data Driven Documents. It's a JavaScript library for creating dynamic and interactive data visualizations in the browser.

D3 is built to work with common web standards – namely HTML, CSS, and Scalable Vector Graphics (SVG).

D3 supports many different kinds of input data formats. Then, using its powerful built-in methods, you can transform those data into different charts, graphs, and maps.

In the Data Visualization with D3 courses, you'll learn how to work with data to create different charts, graphs, hover elements, and other ingredients to create dynamic and attractive data visualizations.

Basic intro about Interface class in Java

NSP.Mathi — Fri, 14 Jul 2023 14:08:22 +0000

Why should we used Interface class?

Usually an Abstract method inherited other abstract class properties and method but it doesn't inherited a constructor. So, then we use interface class and it doesn't have any properties. It have only methods. it only inherited interface constructor. if we inherit a interface class to other class we should use implements keyword.

Parent Class:

public interface class Animal {   
//Statement
public interface walk();

}

Child Class:

public class Dog implements Animal {   

public interface walk(String name, String email){
//Statement
}

}

Access modifier

NSP.Mathi — Tue, 11 Jul 2023 03:49:11 +0000

In Java, are there clear rules on when to use each of access modifiers, namely the default (package private), public, protected and private, while making class and interface and dealing with inheritance?

Ans:
private hides from other classes within the package.
public exposes to classes outside the package.
protected is a version of public restricted only to subclasses.

For example, if I have MyClass and I'm doing AnotherClass extends MyClass I will have access to all protected and public methods and properties from within AnotherClass. If I do MyClass myClass = new MyClass(); in AnotherClass somewhere - let's say the constructor - I will only have access to the public methods if it is in a different package. Note that if I do = new MyClass() { @override protected void protectedMethod() { //some logic } }; it appears that I can access protected methods, but this kind of the same as extending it, but inline instead.
