How to calculate tax amount?

Calculate your payable tax based on your total taxable income.

Environment variable What, Why, Where and How?

What is environment variable?

Environment variable is variable which holds the path of the software installed in your machine.

Why do we need to set environment variable?

When we compile and run any program, then machine try to find the required compiler or runtime to perform the action which we have requested. So either we to have to specify the directory of the software library every time with our command or we could set it into an environment variable so machine can automatically pickup the library path from there based on the command.

For example:

We set python variable to compile and execute the Python code.

python = C:\Python\Python27\python.exe

We set the JAVA_HOME for compile and run the Java programs.

JAVA_HOME = C:\Program Files\Java\jdk1.8.0_201

We set MVN_HOME for maven build.

MVN_HOME = D:\apache-maven-3.6.0\bin

Instead of creating all these variable we could also just add these library paths in a common user variable PATH and later add PATH variable in system variable CLASSPATH.

How to set environment variable?

Right click on my computer icon and select the properties option.

A new window will be get opened. Now click on the advance system settings

advance-system-settings-environment-variable

Now click on the environment variables button.

environment-variables

Now here you could either add the installed library path under the PATH user variable to you could create a new user variable and later add the newly create variable in CLASSPATH system variable.

Why we need Python to run Node.js?

Node.js is written on c++, and is build on GYP. GYP is a Meta-Build system: a build system that generates other build systems and help us to build the large project that needs multiple platform to build. GYP is developed and written using Python, so to build and run few modules of Node.js we need Python.

Therefore wherever we need node-gyp to build any node module, Python will be required.

References:

Error: Can't find Python executable "python", you can set the PYTHON env variable.

This error you are getting because npm need Python and your computer doesn't have Python install into it.

So please go ahead and install the Python in your machine, and run the npm install command after installing the Python.

How to install python?

Go to the Python official website and download the latest release of Python, and simple install it.

Once installation has been successfully completed, then set the python variable in your machine environment variable. To know more, you could see our blog on How to set an environment variable in windows.

Or you could set the variable using this command.

npm config set python C:\Python\Python27\python.exe

If you don't wants to install Python manually and wants all things to be get downloaded by npm itself then you could run npm install -g windows-build-tools, this will download all the required dependencies for you and bring npm in working mode.

To run this command please make sure you have open your node command prompt and cmd with administrative privilege. To do so, go to start and search for node cmd and cmd >> then right click on the application shortcut and use the option run as administrator.

after that just copy and paste the command

npm install -g windows-build-tools

This command will download the Python and install the Python at the below directory in your machine. Go to this path and find the python.exe and set environment variable in CLASSPATH variable.

C:\Users\nodejs\.windows-build-tools\python27\

how to set environment to apply the spring application properties file

By default, application.properties file is picked by system for configurations properties. If you have different properties files available to run the application on the different environments then we need to add spring.profiles.active=<environment name> which is present in the application.property file name.

For example, if our application properties file has profile "dev", and the complete file name is application-dev.properties, then we need to set spring.profiles.active=dev in application.properties file, this way application will pic the right configuration file.

Hope this helps!

Accordion component

Accordion using simple html and css

In this tutorial we are going to create an accordion just using the simple HTML, JavaScript and CSS, as shown below Accordion example picture.

Accordion example

Here is the complete code snippet which we could use to design the same accordion as shown above.

<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.accordion {
  background-color: chartreuse;
  color: #444;
  cursor: pointer;
  padding: 18px;
  margin: 5px 0px 0 5px;
  width: 100%;
  border-top: 1px dotted #0069b9;
  text-align: left;
  
  outline: none;
  font-size: 15px;
  transition: 0.4s;
  transform: skew(-20deg);
}

.active, .accordion:hover {
  background-color: #ccc;
}

.accordion:before {
  content: '\002B';
  color: #777;
  font-weight: bold;
  float: left;
  margin-right:10px;
  margin-left: 0px;
}

.active:before {
  content: "\2212";
}

.panel {
  padding: 0 18px;
  background-color: white;
  max-height: 0;
  overflow: hidden;
  transition: max-height 0.2s ease-out;
}
</style>
</head>
<body>

<h2>Accordion with symbols</h2>
<p>In this example we have added a "plus" sign to each button on the left side of the accordion section. When the user clicks on the button, the "plus" sign is replaced with a "minus" sign.</p>
<button class="accordion">Accordion 1</button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
</div>

<button class="accordion">Accordion 2</button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
</div>

<button class="accordion">Accordion 3</button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
</div>

<script>
var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].addEventListener("click", function() {
    this.classList.toggle("active");
    var panel = this.nextElementSibling;
    if (panel.style.maxHeight){
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + "px";
    } 
  });
}
</script>

</body>

Baat karni mujhe mushkil kabhi aisi to na thi | BAHADUR SHAH ZAFAR

baat karni mujhe mushkil kabhi aisi to na thi

jaisi ab hai teri mahfil kabhi aisi to na thi

le gaya chhin ke kaun aaj tera sabr o qarar

be-qarari tujhe ai dil kabhi aisi to na thi

us ki aankhon ne KHuda jaane kiya kya jadu

ki tabiat meri mail kabhi aisi to na thi

aks-e-ruKHsar ne kis ke hai tujhe chamkaya

tab tujh mein mah-e-kaamil kabhi aisi to na thi

ab ki jo rah-e-mohabbat mein uThai taklif

saKHt hoti hamein manzil kabhi aisi to na thi

pa-e-kuban koi zindan mein naya hai majnun

aati aawaz-e-salasil kabhi aisi to na thi

nigah-e-yar ko ab kyun hai taghaful ai dil

wo tere haal se ghafil kabhi aisi to na thi

chashm-e-qatil meri dushman thi hamesha lekin

jaisi ab ho gai qatil kabhi aisi to na thi

kya sabab tu jo bigaDta hai 'zafar' se har bar

KHu teri hur-shamail kabhi aisi to na thi

----------------------------------------------------------------------------

بات کرنی مجھے مشکل کبھی ایسی تو نہ تھی

جیسی اب ہے تیری محفل کبھی ایسی تو نہ تھی

لے گیا چھین کے کون آج تیرا صبر و قرار

بے-قراری تجھے ای دل کبھی ایسی تو نہ تھی

اس کی آنکھوں نے خدا جانے کیا کیا جادو

کی طبیت میری میل کبھی ایسی تو نہ تھی

عکس-ا-رخسار نے کس کے ہے تجھے چمکایا

ٹیب تجھ میں مہ-ا-کامل کبھی ایسی تو نہ تھی

اب کی جو راہ-ے-محبّت میں اٹھائی تکلیف

سخت ہوتی ہمیں منزل کبھی ایسی تو نہ تھی

پا-ا-کبن کوئی زندان میں نیا ہے مجنوں

آتی آواز-ا-سلاسل کبھی ایسی تو نہ تھی

نگاہ-ا-یار کو اب کیوں ہے تغافل ای دل

وو تیرے حال سے غفل کبھی ایسی تو نہ تھی

چشم-ا-قتل میری دشمن تھی ہمیشہ لیکن

جیسی اب ہو گئی قتل کبھی ایسی تو نہ تھی

کیا سبب تو جو بگڑتا ہے 'ظفر' سے ہر بار

خو تیری ہر-شمائل کبھی ایسی تو نہ تھی
