School management systems (SMS) in India are digital platforms that allow schools to manage their administrative and academic operations efficiently. SMS platforms are designed to streamline the administrative tasks of schools, such as student registration, attendance management, exam management, grading, scheduling, and communication with parents. They also allow teachers to manage their classroom activities, such as lesson planning and homework assignments, and enable parents to stay informed about their children's academic progress.
There are several school management system providers in India, offering a range of features and functionalities to meet the specific needs of schools. Some popular SMS providers in India include:
Fedena: This is a comprehensive open-source school management system that includes features such as student management, employee management, library management, and more.
MyClassboard: This platform offers features such as admission management, student information management, and exam management, among others.

6 Ways to safely work with your Password Manager
Published: 2023-02-23 10:43:00

In light of the recent LastPass Data Breach incident, we are providing you with helpful pointers on How to use a strong Master Password using a Password Manager. 

As LastPass’s first data breach occurred in August 2022, the **[Password Manager Company](https://mverve.com/6-ways-to-safely-work-with-your-password-manager/)** warned their customers about an ‘unknown threat actor’ that may attempt to use brute force to guess master passwords/target customers with phishing attacks/credential stuffing as the actor had accessed their cloud-based storage environment and encrypted password vaults.

Read more about this at https://blog.lastpass.com/2022/12/notice-of-recent-security-incident/ 

A **[Secure Password Protection Manager](https://mverve.com/6-ways-to-safely-work-with-your-password-manager/)** Tool allows you to save and manage all your password protection in one space so that you don’t have to remember unlimited passwords under some password policy. Here are some of the security measures that you can adopt while creating a Master Password: 

Use a Unique Password: Make sure your Master Password is different from your existing application/account personal passwords viz. G-Mail, Facebook, Instagram to ensure your password manager doesn’t get compromised if one of your other online accounts gets hacked due to weak passwords. 
Keep it safe: Don’t write down your master password or share it with anyone. If you need to remember it, try using a mnemonic device or password manager tool to manage the password lists to help you recall it. Don’t use any device for password saving. Avoid saving passwords on your mobile device. 
Make it strong: Create a strong password that is difficult to guess by anyone by making it at least 12 characters long and using a combination of upper and lowercase letters, numbers, and special characters so that no one break the security breach. E.g., Setting Confetti’s!442 as C0nfett!5!442 
Avoid including Personal Information: Don’t include personal information in your master password that is directly related to you. E.g., your name or your home address. 
Use multi – factor authentication: Enable two-factor authentication (2FA) for your password manager to add an extra layer of security in case your master password is compromised. This will require you to enter an additional code (such as a one-time passcode sent to your phone) to access your password manager. 
Update it regularly: Change your master password every few months, or whenever you think it may have been compromised to keep your password manager secure for a security update. 

It is important to remember that the no cryptographic algorithm is completely hack-proof. As computing power and methods of attack continue to evolve, it is possible that new techniques may be developed that could potentially be used to break these cryptographic algorithms. For this reason, it is important for users to choose strong, unique passwords, complex passwords, and password protection while using a password manager to help protect their accounts.
Create a NuGet-Package
Tags: dotnet, cli, nuget
Published: 2023-02-23 10:34:00

In my day-to-day job we have a lot of projects that need to pull in the same internal libraries over and over again.

So we decided to create NuGet-Packages for these libraries and create a local feed, from which we can pull in the NuGet-Packages from our different projects.

These are the steps to create your own NuGet-Packages and use your own local feed.

## 1. Create a manifest
The `.nuspec` file is the NuGet-Packages manifest and defines the different values of the package. Like the name, description, version, etc..

You can run the following command in a developer command line to create the manifest file.

```powershell
nuget spec
```

## 2. Create a package
You can execute the following command in a developer command line to actually create the package, based on the previously created manifest.

```powershell
nuget pack
```

## 3. Add NuGet-Package to local feed
To add the created NuGet-Package to a local feed you can execute the following command in a developer command line.

```powershell
nuget add MyPackage.1.0.0.nupkg --source \\my_server\my_local_feed_share
```

## 4. Add local feed to Package sources
To actually find the NuGet-Packages from the local feed, you need to add it to the package sources.

In Visual Studio navigate to `Tools > Options > Nuget Package Manager > Package Sources` and click on the green `+` icon to add a new source. Provide a `name` and a `source` for your local feed.

After that you are able to browse your local feed when managing NuGet-Packages for a project.
What's in it for me?
Tags: career, management, community
Published: 2023-02-23 10:09:38

Why people join meet-ups, tech communities & guilds? Why invest their personal time and attend or speak in events for free? Even conduct tech workshops where they have to make sure attendees do the learning by doing and grow.

This is a big undertaking and not an easy one! In community events no-one gets paid it's all by the people for the people. I'm involved in organising AWS User Group Dubai Meetups and doing it "consistently" for past many months. But why?! 

For me, there are 2 simple reasons

1 - At every stage of my career, someone was there to show me how to do it right. I was a mobile application developer and from there transformed my career into cloud. Number of people helped me achieve this goal. It's a debt, time to pass it on!

2 - When everyone is growing then the overall culture of growth and right mindset kicks in. Have to create a snowball effect where right discussions happen, skills are valued and people thrive. 

To achieve this, I'm going to conduct a workshop on "[Serverless Architecture for Beginners](https://www.meetup.com/aws-dubai/events/289456898/)" @ [Murdoch University Dubai](https://www.murdochuniversitydubai.com) on 10th of November 2022. And I will continuously organise events where everyone at every level of their career can participate and have an impact.``

Object-Oriented Design: The Key to Scalable and Maintainable Software
Tags: designpatterns, computerscience
Published: 2023-02-23 10:00:00

Object-oriented design (OOD) is a software design paradigm that focuses on the organization and relationship of objects in a system. By using OOD principles, developers can create more scalable, maintainable, and reusable software.

## **What is Object-Oriented Design?**

Object-oriented design is a software design paradigm that focuses on the organization and relationship of objects in a system. In OOD, objects are the basic building blocks of a system, and they interact with each other to perform certain tasks. Objects have both data (attributes) and behavior (methods) and they are organized into classes and hierarchies.

OOD is based on several principles such as: Encapsulation, Abstraction, Inheritance and Polymorphism. Encapsulation is the practice of hiding the implementation details of an object and making it accessible through a well-defined interface. Abstraction is the process of identifying the essential characteristics of an object and disregarding the non-essential ones. Inheritance is the ability of an object to inherit the properties and behavior of a parent object. Polymorphism allows objects of different types to be treated as objects of a common type.

## **The Benefits of Object-Oriented Design**

Object-oriented design provides numerous benefits for software development, including:

- **Scalability:** OOD allows for the creation of a flexible and modular architecture, making it easier to scale a system as needed.
- **Maintainability:** OOD promotes the use of encapsulation and abstraction, making it easier to update and maintain a system.
- **Reusability:** OOD allows for the creation of reusable and modular code, reducing the need to reinvent the wheel and increasing the quality of the codebase.
- **Easier to understand and modify:** OOD promotes the use of clear and consistent naming conventions, making it easier to understand and modify the code.

## **An Example: BankAccount**

An example of an object-oriented design is a bank account system. A bank account system can be modeled as an object, with attributes such as account number and balance, and behaviors such as deposit and withdraw.

This object can be further organized into classes, such as checking and savings accounts, each with their own specific behavior. Additionally, the bank account class can inherit from a more general "Account" class, which could contain common behavior and attributes shared by all types of accounts.

## **Conclusion**

Object-oriented design is a powerful software design paradigm that allows for the creation of scalable, maintainable, and reusable software. By understanding and applying OOD principles, developers can create more efficient and effective software that is easy to understand and modify. So, start exploring the world of object-oriented design and see how it can benefit your software development process.

Scope and usage of let , var & const keywords
Published: 2023-02-23 08:58:03

#### for changing of values of var 

```
var name =" jai";
var name = "ram" ;
console.log(name)
```
This console prints the value of **ram**  , var overrides the value of name.  This causes problem while debugging the code and increases the ambiguity of code .


#### For changing values of let 

```
let  name =" jai";
let name = "ram" ;
console.log(name)
```

 We can see error that identifier name has been already taken , so let keyword not allowing reinitialization of  identifier name , we need to **use different names for the let keywords**. 

#### For changing values of const 

```

 const name ="jai";
  const name =" ram";
console.log(name) 

```
This console shows error that  name has already assigned .


**So its better to use  const for variables 

let for if there is any changing of values 

var is least prioritized **

  


## For usage of var in scope 

```
var  fun ;
for (var  i = 0; i < 3; i++) {
  if(i ==2){ fun =() =>{
    return i; }
  }

}
console.log(fun());
```



when var is declared it is considered as **global variable** . The above  console returns the value of 3 , because as the for loop iteration changes the i value by increment , so var i takes i value  and returns as 3 .

## For usage of let in scope 

```
let  fun ;
for (let  i = 0; i < 3; i++) {
  if(i ==2){ fun =() =>{
    return i; }
  }

}

console.log(fun());

```


  
Let is considered as block variable (within in the scope )
From the above code it returns the value of i as 2 ;
**logically this result  was correc**t .
  
  From above Global scope of two keywords we  see they were returning  variables with different outputs  

 let keyword update was came in ES6 , we need to use let instead of var because of let keyword scope , updating values , 

So Finally 

         ## const >>> let >>> var
