Introduction to chúng tôi Session

ASP.NET Session is simply a state from which we can retrieve the user’s values and store them in the web page session. It is the way in chúng tôi to ensure that the information is passed from one page to another. Whenever the user interacts with any application on the website, firstly, it enables the start of the new session and users to do many operations like reading and writing on the websites. These values can be stored in the session object, which will be stored on the server side. Also, for that particular user, it can use that value on any page on the same website. So, every value has a unique ID.

When does the chúng tôi Session Start?

We all must have a basic question when does it exactly start? So, it will begin when we hit the website. The chúng tôi session will be generated as soon as the first request has been made to the web application. By default, the session state is in Process. The session starts when a user hits any website or application for the first time. If the user is inactive or doesn’t do anything longer on the same page, the server places the session memory allocated for the user. Now, if the user hits the page after the session expiration again, a new session will be created and assigned for the user request. As it is server-side functionality, Session variables are not accessible by the website user.

Let’s have a look at how chúng tôi Session gets started in below four ways:

1. When a user sends or requests for a URL that identifies an chúng tôi File in that application. Session_OnStart event procedure is included in chúng tôi File for that application.

2. The session object is used to store the user values.

3. Whenever the server receives a request with no valid SessionID cookie, a new session gets started.

When a new user visits or hits the application website, we can say that Session_Start is fired.

When does the chúng tôi Session End?

We have seen when exactly the chúng tôi session starts; let’s see when exactly it ends.

Many of us experience this scenario of session end. When we are on a web page of an application for a longer time, and we have not requested or refreshed that page for a longer duration, then the session will end automatically.

When the web server collapses, the user session may get ended.

By default, the value for the timeout is 20 minutes.

We can manually set it as a session if we want to reduce session timeout. Timeout Property.

We can set its value according to our requirements for the web application. A shorter session timeout will help to reduce the strain on our server’s memory resources.

Also, if we want to close or end the session purposely, we can use the method Session. Abandon of Session Object.

Sessions that do not have any state will automatically end. Due to the stateless session, its session object doesn’t contain any content or static object.

Examples to Implement chúng tôi Session

Let’s take an example of a Session that will give us a better understanding. This example contains creating a new session and storing its mail id.

1. Default.aspx

This chúng tôi code will allow the user to design its website or application by designing the user interface.


<%@ Page Title="Home Page"Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" .auto-style1 { width: 100%; } .auto-style2 { width: 105px; } 2. Default.aspx.cs

Default.aspx.cs will allow the developer to write their C# code to develop the website of an application.


usingSystem; usingWeb.UI; namespaceSessionExample { public partial class _Default : Page { { if (password.Text=="edu123") { Session["email"] = email.Text; } if(Session["email"] != null) { Text = "Email is stored to the session."; Text = Session["email"].ToString(); } } } }


In the above snippet, it is evident that the session stores the email “[email protected]”


We have learned about chúng tôi sessions in this article. I hope now it is very clear about when the chúng tôi Session gets started and ends. With the help of an example, it is clear what exactly the session is and how it deals with any web application. chúng tôi web application will, by default, create a session for data storage for users.

Learn How Does Either Works In Haskell?

Introduction to Haskell either

In Haskell either is used to represent the possibility of two values. Either is used to represent two values that can be correct or error. It has two constructors also which are named Left and Right. These constructors also represent and show some purpose either in Haskell. Here Left constructor will show the error value, while on the other hand Right constructor will show the correct value. In the coming section of the tutorial, we will see how this function works in Haskell in more detail, and also we will see its implementation and usage while doing programming in Haskell.

Web development, programming languages, Software testing & others

In this section we will see the syntax for either in Haskell, which is given by their official documentation, let’s have a closer look at the syntax of it for better understanding see below;

data Either a b

As you can see in the above line of syntax we have its basic definition with us. Here we are using either keyword followed by two values ‘a’ and ‘b’. Let’s have a look at the practice syntax for either, which will be more helpful to get a better idea for either in Haskell for beginners to see below;


let variable_name = Your_constructor "value if any" :: Either a basic How does either work in Haskell?

As we already know that either is used to represent two values which can be either correct or error. It also contains two constructors which further used to represent these values in Haskell either. So by the use of either, we can represent our value which is either correct or error. In this section we will first see its definition by the Haskell documentation to get a better idea, let’s get started to see below;

Method signature:

As you can see in the above line of definition for either in Haskell, is given by the Haskell official documentation. This is available inside the Data library, so we can use it as Data.eithe in Haskell. Also if we can see this closely we have two values here ‘a’ and ‘b’. These values are represented by the Left and Right constructor which will turn represent the value as correct and error. After the ‘=’ operator in the above definition, we are trying to represent the ‘a’ value by the Left constructor, and ‘b’ values is represented by the Right constructor. Below we will see the detailed description of both these constructors for better understanding see below;

Available Constructor:

1. Left: As per the official documentation of the Haskell, and as per the convention Left constructor in either is used to represent the error value. Below see the syntax to use it for better understanding see below;


Left a

1. Right: As per the official documentation of Haskell, and as per the convention Right constructor in either is used to represent the correct value. Below see the syntax to use it for better understanding see below;


Right a

1. isRight: This method is used to check whether we have passed the right value or not. It will return us the Boolean true or false. If the value if Right value then it will return true else it will return false. Below see the definition of the method as per the Haskell documentation for better understanding see below;


Now we will see one practice syntax how we can use this while programming in Haskell;


isRight (Right "your value ")

As you can see in the above line of code we are using the isRight method followed by the Right value passed inside the bracket. In this way, you can use it to evaluate the result of the passed value.

2. isLeft: This method is used to check whether we have passed the left value or not. It will return us the Boolean true or false. If the value is Left value then it will return true else it will return false. Below see the definition of the method as per the Haskell documentation for better understanding see below;



isLeft (Left "your value ")

As you can see in the above line of code we are using the isLeft method followed by the Left value passed inside the bracket. In this way, you can use it to evaluate the result of the passed value.


1. In this example we are trying to identify the value as string or int by using the either Left and Right constructor available. Remember if you want to use either while programming does not forget to import this in your program otherwise it will not work.


import Data.Either main = do print("Demo to show wokring of either in Haskell !!") print("Using either to evaluate the value either instance of string or inte using either in Haskell !!") let val1 = Left "Hello" :: Either String Int let val2 = Right 100 :: Either String Int let val3 = Left "Hellow world" :: Either String Int let val4 = Left "I m string !!" :: Either String Int let val5 = Right 900 :: Either String Int let val6 = Left "I am another string" :: Either String Int let val7 = Right 500 :: Either String Int print("Printing the result after either evalution !!") print("result one is :: ", val1) print("result two is :: ", val2) print("result three is :: ", val3) print("result four is :: ", val4) print("result five is :: ", val5) print("result six is :: ", val6) print("result seven is :: ", val7)



By the use of either in Haskell we can easily identify the passing value is correct or error. We also have so many methods available which can be used either to get the result fast for passing Right and Left value in Haskell. Mainly it is used to show the possibility between the two values either a or b.

Learn How Does Azure Monitor Work With Its Types?

Introduction to Azure monitor

Hadoop, Data Science, Statistics & others

What is an Azure monitor?

The Azure monitor supports the user to achieve maximum performance in services and applications. As discussed above, the below points stress the necessity and application of Azure monitor. It diagnoses and detects the bug in any application with its feature called application insights. It can compare the infrastructure flaws with container and VM insights. Then it can penetrate the application and monitor data with analytical log details to troubleshoot and work on deep insights. It supports operations at a finite scale by using its automated actions and smart alert systems. Finally, it can develop visualization with workbooks and Azure dashboards.

How does Azure monitor work?

The infrastructure of the Azure monitor has a high-level view. The metrics and logs are placed at the center of the Azure monitor, which works on two important types of information used by the Azure monitor. In the right of the Azure monitor, there are resources to work on the data monitoring events which populate the data stores. On the other end, Azure monitor work on different functions which work on the collected data. It also performs alerting, analysis, streaming, and other actions to its external connected systems.

In simple, it can be termed as: Azure monitor gathers the information from different sources like operating systems, applications, various resources of Azure in the formats of logs and metrics. It can then be processed to work on different functions like visualization, automation, integration, alert systems, and deep analysis.

Metrics are coined as a measurement to view aspects of resources. For example, it helps to check on the number of connections, disk IOPS, CPU utilization, swap space, memory utilization, etc. It is real-time and saved as a finite value with a periodic collection interval. Therefore, it is adapted to the environment better, and the collected logs are displayed as graphs concerning time and performance.

Logs are a collection of records with metadata and different properties that have a simple structure and provide an organized view of the SQL database. It is comprised of numerical information like metrics which has brief text with extra information. Traces and events are the best examples of logs. It is a dash of data that periodically collects the data which needs to be manipulated to view. The user wants to extract and filter the data from the logs by using a native query called kusto query language. It can be used to produce some logical visualization, and it can be pinned to dashboards.

Azure Monitor types collect

Application data: The information about the compiled code’s functionality and performance irrespective of any platform is collected from the application monitoring data.

Operating System data: The information about the operation system on which the user is hosting the application is collected in Guest monitoring OS data. It can be another cloud, Azure, or on-premise.

Resources on Azure data: The information about the process of an Azure resource is collected in Azure resource monitoring events.

The subscription on Azure data: Azure’s proper health check process manages the information about the management and operation of subscriptions in Azure.

Key requirements

The alert system is one of the key requirements for Azure monitor. It proactively alerts the user when the application is facing critical conditions and requires some corrective actions. The alert rules depend on metrics provided in real-time based on numerical values. In addition, it is based on logs which enable solving complex logic across the data from multiple resources.

Azure monitor application insights

Monitoring the information is useful only if it enhances the visibility of the process in the computing environment. The insights offer a customized monitoring experience for a few particular services. It provides minimal configuration and enhances visibility in the area of critical resources. Application insight always monitors the performance, availability, usage, swap space, and memory allocation of the web application deployed on on-premise or cloud. It structures the powerful data in the Azure platform to offer the user a deep view of the application’s performance. It allows the user to detect errors without any delay and report them to him. The application insight enables different points in development tools and combines them with visual studio to support the process in DevOps.

Azure Monitor Visualizing monitoring data

The visualization in Azure monitor offers tables and charts as effective tools for succinct the monitoring data to display it to a different set of audience. In addition, it has its features to visualize the monitoring data and structure the services of Azure to telecast to the audience. Apart from charts and tables, the monitor has attractive dashboards, workbooks, and power BI to consolidate the performance of the application and display it to the user for better understandings.


Once the Azure subscription is activated, the azure monitor performs and monitors all the addition of resources like web applications and virtual machines. The Azure monitoring begins to collect the data, and the activity logs are recorded when all the resources are developed or edited. The metrics explain the performance of the resources. The diagnostics enable options to allow the user to maximize the availability of the data, and the agent addition option is there to compute the resources to gather info from telemetry from guest OS.

How To Start A Music Blog

A music blog is a website that typically publishes music tutorials, song lyrics, popular singers, and more.

If you’re looking to make a music blog, you don’t have to code.

Instead, you can use a CMS (content management system) like WordPress (.org).

WordPress is used by over 40% of all websites on the internet, and it’s the gold standard for website creation.

This quick and easy guide teaches you how to start and monetize a music blog with minimal expenses.

Just so that you know you’re in good hands—I’m the founder of this website (that’s also built on WordPress).

In addition, I have multiple years of experience in SEO, blogging, and website creation.

Here is how to start a music blog in 7 easy steps:

1. Get web hosting

To get your music blog up and running, you need to get web hosting.

SiteGround hosting is highly recommended because it’s fast, secure, and reliable.

Choose between 3 plans—StartUp, GrowBig (recommended), or GoGeek.

2. Choose a domain name for your music blog

Other extensions like .org, .net, or .io, are fine too, but they are not the most common.

A simple way to come up with a good domain name is to combine “your niche” + “a related word” together.

Review the order and pay using a debit/credit card.

3. Install WordPress

Select “Set Up Website” to start the installation process.

Select “Start New Website” and select “WordPress”.

Choose if you want to add extra services.

Select “Finish” and wait for WordPress to install.

Tip: If you need help with the installation process, you can contact SiteGround’s 24/7 support for help.

4. Choose a theme

Once WordPress is finished installing, you need to choose a theme (the design of your blog).

For a music blog, I recommend buying a premium theme like GeneratePress, Divi, or Astra.

Tip #1: You can find great WordPress themes on EnvatoMarket.

Tip #2: If you need help with customizing your theme, you can contact your theme’s support.

Tip #3: You can create a music logo for free using Namecheap’s logo maker (it’s the best logo maker that I’ve used).

5. Install plugins

Recommended plugins to install:

Google Site Kit – Easily connect your site to Google Analytics to see real-time visitors and stats.

Yoast SEO – An all-in-one SEO plugin for WordPress that you can use to add an XML sitemap (a site directory).

Jetpack – A security, speed, and stats plugin.

6. Start posting music content

Since you’re starting a music blog, you need to research topics to write about.

You can write about music guides (e.g. Rush E sheet music), lyrics (e.g. Despacito lyrics), the latest songs/albums, pop star news, top songs (e.g. best heavy metal songs), and more.

To find content ideas, you can use the Google Keyword Planner or browse similar blogs for inspiration (e.g. Pitchfork, Rolling Stone, Loudwire).

When writing your post, make sure to include headers, spacing, lists, and media to engage your readers.

You can also add categories and tags to your post on the right sidebar.

Tip #1: If your blog is new, your posts will start ranking on Google after 3 to 6 months (if they are of quality).

Tip #2: Try targeting low-competition keywords like “Best electro swing songs” instead of “Best EDM songs”.

7. Monetize your music blog

Once your music blog gains some traffic, you can start monetizing it.

I recommend applying for Google AdSense or Ezoic.

Before you apply to either one, make sure that your blog has a privacy policy and an “About” page.

If you’re a producer, you can sell your beats on BeatStars and promote them on your blog.

You can also complement your blog with a YouTube channel (if you haven’t started one yet).

Tip #1: Ezoic earns about 5x more than Google AdSense because of its technology.

Tip #2: After you’ve reached 50k or 100k monthly visitors, you can apply for Mediavine or Adthrive (both are premium ad networks).

How Does Responsibility Center Work?

What is Responsibility Center?

The term “responsibility center” refers to the operational units within an organization that are accountable for the activities specially designed for them.

These units usually have their staff, goals & objectives, and policies & procedures. These units also manage matters related to revenue generated, expenses incurred, and funds invested in their activities. This arrangement is usually seen in large multinational companies, where the organizational tasks are divided into multiple subtasks. The responsibility centers assign each task to a small division or group.

Key Takeaways

Some of the key takeaways of the article are:

The responsibility center refers to the operational units within an organization that have well-defined individual targets to fulfill and are accountable for them.

Large organizations usually divide their work into smaller subgroups so that every unit achieves its goals that all add up to fulfill the overall organizational objectives.

These units have their staff, goals & objectives, and policies & procedures.

There are four significant types of responsibility centers – cost center, revenue center, profit center, and investment center.

How does Responsibility Center work?

In a large organization, all the tasks are split amongst smaller teams focusing on their respective objectives. These small units work synchronously to achieve the overall organizational goals.

Each unit has its targets and goals, which they are expected to achieve within a pre-defined timeline. These subgroups use their resources, follow procedures, prepare financial reports, and bear responsibilities. Although they function independently, they tend to contribute toward the common organizational objective.

Types of Responsibility Center

There are four significant types of responsibility centers – cost center, revenue center, profit center, and investment center.

1. Cost Center

It is a unit that allocates, supervises, segregates, and eliminates different kinds of cost-related issues of a company. The primary responsibility of a cost center is to manage the company’s costs and check its unwanted expenditures. Under the cost center, the manager is responsible for all expenses, including maintenance, production, HR, etc.

2. Revenue Centre

It is accountable for generating and monitoring revenue. The management has hardly anything to do with control over cost or investment-related issues within the organization. Comparing the budgeted revenue with the actual payment determines the performance of the revenue center.

3. Profit Centre 4. Investment Centre

It is primarily responsible for investment-related of the organization. The manager may need to control income and expenses in order to manage profitability, which they eventually invest in other assets.

Examples of Responsibility Center

Let us look at a simple example to decipher the role of the responsibility centers within an organization.

ABC Inc. manufactures a range of denim wear, such as pants, shirts, tops, etc. The company often invests huge capital to carry out large business operations or expand. And like any other business, it manufactures goods and sells them in the market, generating revenue.

Hunting for the best investment choice is not the same as looking for a profitable market. The former analyzes return on investment, while the latter intends to maximize profit. Large organizations subdivide tasks into small units or groups.

Importance of Responsibility Center

The process of creating responsibility centers helps an organization achieve its overall goals. In this arrangement, the tasks are segregated and tagged to many managers, allowing proper delegation and control. Without responsibility centers, it will be difficult for organizations, huge multinational companies, to manage their operations and achieve their overall organizational goals and objectives. This is because these units with an organization are analogous to the different parts of the human body.

Advantages of Responsibility Center

First, given that there is a responsibility assigned to all the units, each individual has responsibilities aligned with the roles that direct them toward a common purpose.

Since senior management tracks and reports individual performances, each individual tends to give their best performance.

It facilitates better delegation and control of organizational tasks, which is one of the objectives of management.

First, a conflict of interest may arise between the individual objectives and the organizational goals.

The management must invest a lot of time and effort to plan and meticulously chalk out the course of action.

Sometimes, the employees or managers are resistant/ reluctant to join a particular department/ segment/ role.


So, it can be seen that responsibility centers are essential cogs in any organizational machinery. It can help organizations grow and seamlessly manage their activities if implemented correctly and efficiently.

Learn How To Use Scripts In Indesign?

Introduction to InDesign Scripts

InDesign Scripts are code of computer language that helps us perform various tasks in just a few simple steps. We can perform simple and complex tasks with specific scripts, and we have a number of built-in scripts in InDesign under the Scripts panel. The coolest thing about the script of this software is that you can create your own scripts or run scripts created by other people for having a result of your desired task. Here in this article, I will tell you how you can use different scripts of script panel in this software and also tell you how you can install any script from external sources.

How to use Scripts in InDesign?

To start using scripts in this software, you need not worry about it. It is very simple to work with it and use it to have our desired result. So let us start our discussion.

Start Your Free Design Course

3D animation, modelling, simulation, game development & others

I will start our discussion by taking a new document. I will choose this Letter size document from the New Document dialog box of this software.

Here at the right side of the user interface of this software, we have a panel section, and in this section, we can find the Script panel.

I will open the JavaScript folder, and you can see there is a number of the script in this list.

We use this script to align objects in a different manner, such as; you can see there are some options in the panel of AlignToPage script. But, again, I will go with default options this time; it will align our chosen object with the top left corner of the page.

So I will again open this align script panel and enable this ‘Consider Page Margin’ option.

Now let me tell you one of the scripts which we can use for text. When we paste text in the text frame of InDesign given by the client, we face many text formatting errors such as there may be an unnecessary gap, hyphens, tabs space, and so on. So with the next script, we can resolve it.

I have pasted this text in the text frame of this software, and you can see it seems this text is perfectly arranged.

Let me enable hidden characters, and we can enable it from the ‘Show Hidden Characters’ option of the scroll-down list of Type menu.

And you can see it resolve all formatting issue, and the text is perfectly arranged according to the type format.

What if you want to have your own script or want to use the downloaded script from an external source? You can also have this in the Scripts panel also, and it will come under the User folder of this Scripts panel, but if you haven’t any external script, then the User folder will be empty.

You can paste the script code of your desired script here in this folder. For example, I have downloaded a script from the internet and past it in the Scripts Panel folder. You can also paste your own written script code if you know about the Java language.

Now you can see there is our downloaded script in the User folder.

This script is for drawing waves for different data types if you create a design layout for any analysis. But, first, I will take the Frame tool from the tool panel to explain it.

And it will create a wave form like this.

Now I will make some changes in parameters like this.

And you can see according to parameters; it gives a different result.

You can change the colors of waves also.


So now you know how you can interact with the built-in script of InDesign and perform any task by using them. In addition, in this article, you learned how to insert your own or downloaded script in the Script panel of this software for using them in your design layout.
