Web Dev's 2021 Rewind

Mahesh Sv — Fri, 31 Dec 2021 05:27:17 +0000

I know it’s been rough year for all of us, but as Developer who followed the bandwagon so called Data Science in college, ended up falling in love with Web Development after getting job in it, which i never thought, i would do. I wanna share my 2021 Rewind today with you.

My First Online Revenue 🤑

I see lot of people earning money online and feeling so excited. And I just caught up with that feeling when i earned $30 from Blinkist for small contribution i made to their Organisation. That is only the beginning, I have some side projects in works which could lead to some sort passive income in near future, More updates on this later this year. But as saying goes

Taking the First Step🦶 is the Hardest thing to Achieve Million things

Converted to Full Time Employee 💼

I got myself a full time employee in the same organisation(KEKA Inc) where i am doing internship from past 10 months. Let me tell you something, It wasn’t easy. Being able to learn something you never imagined you would, is complex than you think. But its worth a shot, Now i am happy with skills i gained through out this year and in this organisation. I am more excited what brings this New year.

Achieved 15,000 views of my Articles across all Platforms 👀

While, most of my daily life is filled with work. I gave myself some time off from work to write down my thoughts and share it world. As a saying goes

Your knowledge is valuable only when you share with others

And that sharing reached almost 15000 views this year, which is overwhelming 🤯 for me. This kind of achievements pushes me to give my best content, out to the world. Once again, Thank you everyone for reading my content.

Tried and Failed in Mobile Development 📱

Well, I thought at least this year should be the one where i learn Mobile Development. So i did and it did not turned out well. I am not blaming any mobile development, it just the limitation and developer experience that did not satisfied me. It gave me thought how much we can done by Web Development and cross platform. So, i dropped off from Mobile Development.

Got Another Job Offer ➡️ 💼

Yes, Another Door bell 🔔 ring of Opportunity, got another job offer with much higher package and company is working with latest technology. But after going through long thoughts and discussions within myself, i asked myself “Do i need this new job?”, “Is there any need to change my job?” at that moment. I found myself with answer: No

At the End of the Day, all you need is job with work satisfaction and fair income (to live basic life). I am happy in both of these categories. So, I refused the offer.

Anyways, Everything is happens for the best!

Tools, Tech I discovered 🛠️

VERCEL - easy deployment service, Especially for react and NextJS apps → Reference
Importance of CI / CD pipelines and How it makes developers life so smooth → Reference
Tailwind CSS made my css styling life lot more productive, with its all features and latest feature JIT (Just In Time Complier) → Reference

Thank-You Note ✍️

At last but not least, i want to write some thank you note to somethings i am thankful this year.

✍🏻 : Thank you Git, for tracking my miserable file changes and commits.

✍🏻 : Thank you Youtube, for being my virtual tutor always

✍🏻 : Thank you StackOverflow, for being the first to show (on google search) with the fix to the issue although most of us haven’t seen your face (Home page) yet! 🤣

✍🏻 : Thank you Family and Friends. for being there for me when i am in sad, in need, in happy.

That's all for this year!
Signing off for now, it's your neighbourhood coding friend MaheshtheDev

Work-Personal Life Balancing?

Mahesh Sv — Tue, 02 Nov 2021 13:23:14 +0000

Balancing, most people refer it as theory where if we manage to satisfy the couple of things / persons / activities we want to do.

But its easier said than done, Cause i am facing this issue in recent times and i came over it with some small tweaks in my life. Now, i am feeling more alive than ever. So, Today i want to share about it with you guys.

Balancing, what?

Recently, I faced My Work life and Personal life Imbalance. Although, i was working only for a year now. I observed a lot of things changed in me like spending less time in reading blogs, following or writing them. Or working on some cool side project to show off in my portfolio. When i was in college, i had a lot of spare time(Personal life) and some of that time i use to spend creating some cool arts in Figma or watching some tv series.

Since, I'm not representing personal life as Family. Cause, most people of my age do stuff what they want to do instead of spending time with family, at-least most of them come under this category.

Balancing, really!

As i said in the beginning, Balancing is a theory where if we manage to satisfy the couple of things / persons / activities we want to do. So in my case, it is Work Life and Personal Life.

My work life would be the Work related things like working on the task assigned by manager or learning something work related.

My Personal Life would be the watching Tv Series, Reading Articles or writing own articles and spending time on the social media like Twitter, Reddit, LinkedIn sometimes.

In the Beginning days of my work. I wasn't a fully involved in it. But as time passes, work and responsibility has been increasing week by week. To cop up with that, i had to seek more and had to work done more. With that reason, i was not able to do what i use to do in the college.

Due to covid, work culture has been changed from work from One place to work from Any place.

And i missed chance of working with team closely, cause my work life began in the mid COVID 🤒.

To be honest, this gave us advantages and disadvantages. like we can do our work, when we feel like to do as an advantage but in long term its becoming disadvantage to us, like there is no ending time for work in a day. And also I get this imposter syndrome that we never get feeling like we are done for the day.

Balancing Equation (Not Exactly, though🙁!)

So, Now i observed that i am not satisfied with my life. I Started working on the development of habits like Morning Walk, Meditation. Reading Articles whenever i had time in between my work like the time where we run our code builds for ages to check our changes has reflected or not!

And also i started having end time in a day for work. After that end time mostly, i will ignore the work related stuff, instead i spend time with my family or go for a walk with AirPods in My ears by playing fav playlist from Spotify.

Put a Highlight of the Day, I generally make a Highlight of the day, like if i get that thing done on that day, then i am done for the day. This helped me a lot in terms of work satisfaction. Once i am done with that particular task, i just go with flow for rest of the day. Cause, The Toughest part was done for the day.

Thanks for Reading, Hope you like it. Plz let me know by comments 👇.

Programming Case Types !Explained

Mahesh Sv — Sat, 01 May 2021 00:57:46 +0000

No matter how well you are at Coding. Name Conventions can be a pain in the A**.

In the programming world, languages use some specific pattern in naming variables, functions

Jeff Atwood (Stack Overflow Co-founder ) says

“Naming Conventions is one of the two hard things in Computer Science”

Why Case Type?

we all use naming to things we define in the program from variables to functions. In Programming, if you want to name a thing with more than one word you can’t name it with added space or without space directly some times it might mislead the code reviewers/ code readers like therapists can sound like therapists or the rapists.

Here comes the Case Type with a solution where it has different ways to name a thing that has more than one word.

Today, we will look into the Different Case Types in the Programming World

1.camelCase

Camel Case is actually inspired by the animal “Camel”. Where the first word will be small letters and from the second word, the first character will be capitalized like camelCase.

Some of the big companies also inspired by this. Example like iPhone, eBay

Generally, Camel Case is used for Variable Naming

2.snake_case

Snake Case is naming with words separated by _ ( underscore ) and all small letters

Generally, Snake Case is used for Variable Naming

Ex :- snake_case, new_word

3.kebab-case

Kebab Case is naming with words separated by — ( hyphen ) with all small letters

Generally, Kebab Case is used for CSS naming

Ex :- new-word, kebab-case

4.PascalCase

Pascal Case is naming with the First letter of each word is Capitalized.

Generally, Pascal Case is used for Class Naming

Ex :- NewWord, PascalCase

5.MACRO_CASE

Macro case is naming with all letters Capitalized but the words are joined with _ ( underscore)

Generally, Macro case is used for Preprocessor and constants

Ex :- NEW_WORD, MACRO_CASE

6.Train-Case

Train Case is naming with the first character of every word of the name is Capitalised and words are connected with — ( hyphen ).

Ex :- New-Word, Train-Case

How to Learn Any Programming Language(2021)

Mahesh Sv — Fri, 29 Jan 2021 08:21:58 +0000

How to Learn Any Programming Language

Learning Programming Language might seems as hard as it sounds. But in reality, It’s just a Language used for communication between Humans and Electronic Devices.

Compared to Humans Communication languages, Programming Languages have bit more rules, vocabulary/syntax, and Structured pattern.

In this Article, I will discuss about 5 steps, I follow when I’m learning New Programming Language and Highly recommend you to Follow if you fall on to this category.

TL:DR ;

Learn Basics of Programming Language(if you’re Newbie)
Take a look on Language Documentation briefly
Gather best resources like websites, YouTube channels, blogs for your learning programming language
Ask your queries in Language online community like Stack Overflow
Consume and Create. I mean learn stuff and share with it world in a way you understand it

That’s our Outline. Let’s Deep Dive Now!

Learn Basics( For Newbie)

It’s important to know the basics before you dive to the language and crunch their functionalities. Go through the Basics of Programming languages.

If you don’t know where to Start. Feel free to start here → Link

Take a look at the Documentation

Hardest thing and Best thing to do is Reading Documentation. I’m not saying go for line to line. Just go Heading to Heading, you will get to know what do we have in this Language. Later on, you can check the all things in Documentation did you got the concept/ usage of it(after learning language from different resources).

Gather Resources

First thing you need to do when you’re not into Documentation is Figuring out “From where you gonna Learn this Language?”.

Search for Best Resources/ YouTube Channel / Medium publication to Learn Some X Language. Or you can directly search “X Language Beginners Tutorial”, your google feed will be filled with Suggestions

Go through some videos and you will get an idea whom to follow or which resources will teach the best

Follow and Ask Communities

Back in Days, When you have query/Doubt, you go to physical library or Visit Teacher for Doubt session.

Lucky for you, Internet brought you everything in your Figure Tips. They’re Some Great Communities where you can raise your query and get the solution within No Time.

Join in Language Communities like Stack Overflow, Language Subreddit, Follow the Developers who are experienced in the Language

Consume and Create

I’m pretty sure your here to Consume the Content. But Most People failed to share their Learning experience to World.

What I suggest is Share what you learned to World.

If it is small, share it with Twitter, LinkedIn, Reddit Dev Community

If it is Good amount of info to Make Article, don’t hesitate to put out your first article on your new learnings

If it is more than that, Write a Book about all things you learn.

Github CLI 1.0

Mahesh Sv — Tue, 22 Sep 2020 00:03:32 +0000

GitHub is like a Bank to Developer, Where you can store all important code in it and use it whenever and wherever. You might as well know that it offers the distributed version control and source code management functionality of Git.

GitHub CLI is Terminal Interface. Where you can interact with your code on GitHub right from Terminal. This saves few clicks and makes Developer focus less distracted.

So, GitHub launched GitHub CLI. I want to be clear here GitHub CLI is not replacement of Git. GitHub just bringing their services to your Terminal.

You might say that “Hey, Mahesh! I’m already doing everything on terminal”. Of course, you do but GitHub CLI makes that experience now more feasible and flawless. For example, now you can create or resolve issues raised in your GitHub right from your terminal.

They calling it as gh. You need to start command line with starting gh.

Installation:

GitHub CLI is available on Windows, mac OS, Linux

Windows :

You can download directly from Link here
Download it and Open the file you downloaded.
Installation Done

mac OS :

gh is available via Homebrew and MacPorts.

Via brew

brew install gh - Install
brew upgrade gh - Upgrade

Via MacPorts

sudo port install gh - Install
sudo port selfupdate && sudo port upgrade gh - Upgrade

Linux :

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key C99B11DEB97541F0
sudo apt-add-repository <https://cli.github.com/packages>
sudo apt update
sudo apt install gh

So Installation Done, Next step is..

Authentication

We need to authentication GitHub CLI with GitHub Server

gh auth login - for logging in

Basic Commands to get Started with GitHub CLI:-

gh repo clone @username/@reponame - to clone a Public Repo

gh pr create - to create a Pull Requests

gh pr diff - to view difference Pull Request and Master

gh pr merge - to merge a Pull Request

gh pr checks - to check all test cases are passing

gh issue status - to know opened issues for you

If you’re Open source contributor and want to Contribute to GitHub CLI. Contribute here 👉🏻 cli/cli

This is it. Hope this post is helpful to you!

How to Secure API Token

Mahesh Sv — Tue, 28 Jul 2020 09:57:32 +0000

If you are into this tech world for a while. I'm sure you heard about the word API. API is Application Program Interface. For example, Google has API which gives user details access to third party softwares. So basically API acts as bridge to pass secure information to authenticate third party softwares. To authenticate this third parties API token is required.

Many contributors use this API tokens to create some unique products like creating Telegram Bot, Slack Bot. Although product was built successfully. Contributors get recognised by showing their code to Dev Community. To do that they need to secure the API token before they publish it to github.

Table of Contents:
Securing API tokens on Windows
Securing API tokens on Github
Securing API tokens on Heroku

Securing API tokens on Windows:

To secure API token you need to define them in the environment variables.

Search the Environment Variables you will find Edit the Environment variables, open it. you will find these
Then go to Environment Variables. Click on the New button then add the api token with some variable name and note the variable name
After adding this Variable then Restart it.

Now you can use this API token across any code in your local system.

Securing API tokens on Github:

First upload your Repo in the GitHub. Open the Your Repo Settings tab as shown below.

Then open Secrets on the left side as shown in above picture.
Then add new Secret with Var name and API token.
Now this variable works across the Repo.

And Secret Variable won't disclose to any other users or third parties by GitHub.

Securing API tokens on Heroku:

In heroku you can do this in two ways either through Heroku CLI or Dashboard.

Heroku CLI

Open cmd and login to Heroku with Heroku login
Go to your Project Folder
Then use this command heroku config:set S3_KEY=8N029N81 S3_SECRET=9s83109d3+583493190

Now you can use variable name anywhere in the Project

Heroku DashBoard:

First Create app in the Heroku
Goto App settings tab
Goto Config Vars and add your API tokens

This is it. Hope this post is helpful to you!

MAYA by Spotify

Mahesh Sv — Sat, 13 Jun 2020 07:33:54 +0000

Spotify is a leading audio music,Podcast platform in the world right now with 271 million MAU(Monthly active users) and 124 million paid subscribers. This Tech giant experimented a new Concept MAYA with their subscribers. Today, Lets talk about that!

When Spotify was about to launch their product in the Market, They were excited with this new feature that gonna change Digital Music Market called "Discover Weekly".

Discover Weekly is Custom playlist of 30 new songs which you might like to listen or you might want to try new songs which are possibly endup in your curated playlist.This "Discover Weekly" Playlist made by Spotify Ml/AI algorithm using similar genres you like and using some magic trick.

After Successfully lauching the product they found out that this Playlist has a bug that it was showing 8 out of 30 songs which have already been listened by the user or already loved. So as you think, they had resolved it in no time.

They thought now it's gonna take their graph higher than never. Turns out they were wrong(Oops😨!), they found out Customers actually liked the Buggy Algorithm.

Company came up with name of this concept as Mostly Advanced Yet Acceptable(MAYA).

I hope you guys will apply this concept in your daily decisions where you get to highly advanced yet acceptable. Like Pockmen Go, the concept is old but they came up with Virtual Reality(VR) feature[Mostly Advanced Yet Acceptable]

Hoping you like this post!

Math101 for Competitive Programming

Mahesh Sv — Sat, 16 May 2020 10:28:24 +0000

Many of us are trying to do something productive in this Quarantine. This Article is one of them which is gonna help you out of “Fear of Starting Competitive Programming”.
In this Article we will discuss the essential needs of Math Knowledge for Starting Competitive Programming.

Table of Content:

Birthday Paradox Problem
Modular Arithmetic Properties
Inclusion Exclusion principle and programming applications

1. Birthday Paradox:

Birthday Paradox actually states. How many people must be there in a room to make the probability p% that at-least two people in the room have same birthday?. Naive solution is the by finding p(different) and subtracting from 1 equaling it to p(same). After solving you will get the N. Instead of that you can simply use the formula which is actually derived from the above equation is

sqrt(2*365*log(1/(1-p)))

2. Modular Arithmetic Properties:

In competitive programming, Modular Arithmetic Properties are essential tools in solving big number problems. In the Problem statement when they ask to print solution in mod(107+9). It not as sample as it seems. You might get large number before applying mod to it. To simplify, You need have idea on Modular Arithmetic Properties

( a + b ) mod p

When they ask to add sum of two large numbers which get overflow after adding.
Use this Formula

(a+b) mod p = ((a mod p) + (b mod p))mod p

(a*b) mod p

Same case here but when they said to multiply and which result might end up overflow. Use this Formula

(a*b) mod p = ((a mod p)*(b mod p))mod p

3. Inclusion Exclusion principle and programming applications:

The principle of inclusion-exclusion says that in order to count only unique ways of doing a task, we must add the number of ways to do it in one way and the number of ways to do it in another and then subtract the number of ways to do the task that are common to both sets of ways.

And Also Worth Mentioning
L.C.M and G.C.D code
