A little bit about Data Science and Data Scientist

Zubayer Himel — Tue, 02 Jun 2020 20:04:16 +0000

Couple of days ago I took Data Science course of IBM from Coursera. I completed my first course and got basic knowledge about data science. As I am new to this sector I thought I would share what I learned. This will also help me as a future reference 😅. Now lets get started.

Data science and Data scientist

Data science is a field where you use scientific methods, algorithms, processes to get information from a chunk of structured or unstructured data. A data scientist is someone who extract the information from the data. So data science is basically what data scientists do.
Data scientist is a player who only plays with data whether the data is in structured or unstructured form.

Who can be a data scientist?

An ideal data scientist should have curiosity in him/her. Without a curious mind one can't be a perfect data scientist. Now here question may arise why curiosity is important in this field? Curiosity is important because without curiosity a person can't extract the information from a thousand/million/billion set of data. He/She won't get what to extract from the data.
A data scientist has to be a good story teller. He has to make a good story about his finding from the data to present the final result. So a date scientist requires good story telling skill in this field.
Besides these skill a data scientist should have knowledge in STEM(Science, Technology, Engineering, Math) kind of things. Having knowledge in statistics is important. Because these are important and kind of mandatory skills as he/she'll need to analyze data, may need to build an application to extract the information out of data, need to make a chart of the findings etc.

Why data science is important?

Why not it is important??? Now a days data science is used everywhere. We can solve our problems with the use of data science. Data science is future because it predicts future. Data science is related to data mining, deep learning and big data.

That's it. Hope you'll find this useful. 😁

Boost your HTML and CSS writing with Emmet

Zubayer Himel — Tue, 11 Feb 2020 20:00:38 +0000

Emmet is a set of plug-ins for text editors that allow for high-speed coding and editing in HTML, XML, XSL and other structured code formats via content assist. Emmet lets you write less code and do more. In VSCode you can use Emmet without installing it. If you want to get Emmet for other editors like Notepad++, Atom, Sublime text etc you can download and install it.

Basic HTML template: Instead of writing html, header, title, body tag one by one you can simply write ! and press tab. This will make a basic template for you.
Complete html tag: If you want to make a header 1, instead of doing hard code <h1></h1> like this you can type h1 and hit enter, and emmet will create the header 1 tag with closer for you. You can do this for all the HTML tags instead of writing the whole tag by yourself. All you need to write the name of the tag. e.g. div -> <div></div>, header -> <header></header>, p -> <p></p> and so on.
Tags with class: If you want to make a class inside a div you can write .myDiv and hit enter. It will create a div with a class named myDiv. By default anything after dot (.) creates class for a div. You can also do the same for other tags. Write tagName.className and it'll create the class for the specific tag. Lets say, you want to make a class for header 1. Just type h1.myHeader and hit enter

<div class="myDiv"></div>
<h1 class="myHeader"></h1>
<h2 class="myHeader"></h2>
<p class="myParagraph"></p>
<span class="mySpan"></span>
<b class="myBold"></b>

and so on.

Tags with id: Sometimes you may want to give an id to a div. You can do it easily just by pressing #id. Its the same as the class but instead of dot(.) sign you need to use hash(#) sign. Like this h1#header1

<div id="id"></div>
<h1 id="header1"></h1>
<h2 id="myHeader"></h2>
<p id="myParagraph"></p>
<span id="mySpan"></span>
<b id="myBold"></b>

and so on.

More than one class onto the same element: You can create more than one class or id onto the same element. For this you need to write class1.class2 and it will give you

<div class="class1 class2"></div>

If you want to create two class and a id at a time you can simply write class1.class2#myId and hit enter. This will provide you two classes with a id in a div

<div class="class1 class2" id="myId"></div>

You can do this for a header or a paragraph. Just put h1 tag before class1.class2#myId and it will do the same for header 1.

Text inside element: You can write a text inside your element using emmet. If you want to write something inside a header you can write h1{This is header one} and hit enter. It will do the rest for you.

<h1>This is header one</h1

Generate Lorem Ipsum: If you frequently use dummy text for your development and every time you go and copy the text from here then this is perfect shortcut for you. Inside a paragraph tag just write lorem10. This will generate 10 dummy word for you inside the p tag.

    <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Et, quasi!</p>

You can get as much text as you want. Just write your number of words after lorem e.g. lorem100, lorem2000

Child and sibling elements: You can write more than one tag at one go. Let's say you want 5 li inside a ul and that ul should be in a p. So you can write something like this p>ul>li*5, hit enter and emmet will create below code for you -

    <p>
        <ul>
            <li></li>
            <li></li>
            <li></li>
            <li></li>
            <li></li>
        </ul>
    </p>

What if you want to make a form and inside a form you wanna have one text input and a submit button. Write **form:post>input:text+input:s*. It will generate the below code -

    <form action="" method="post">
        <input type="text" name="" id="">
        <input type="submit" value="">
    </form>

These are the shortcuts that I mostly use. But if you are interested for more shortcuts like this for HTML and CSS you can visit this link

Thank you all.
