Career Landscape of Containerization

You Must've Heard/Used Docker

Docker's been around for a while (since 2010) but its widespread usage started just a few years ago with Kubernetes. Literally everyone is using it, that means it's a skill that companies want!

Containerization has marked a new era of microservice architecture. I used it and gotta say its some amazing stuff especially for a developer.

In most cases, college developers like me just focus on making the web app work and deploy it on was, Heroku, Azure, etc on a student dev pack or something else but forgot that companies have different needs and tend to, not use a PaaS (Platform as a Service) for deployment. They prioritize their specific needs and deploy on their own traditional server machines. PaaS like AWS hide this mess and regulate it at the same time ask a ton of money too For Example Apple spends 30 million on AWS per MONTH! no one wants that.

This is where docker and containerization specifically swoops in like superman and saves everyone. It gives developers so much power and scalability at their fingertips that most PaaS charge you for. try to use Docker and Kubernetes specifically. Kubernetes can scale to serve the app to thousands to millions of people. The Likes of IBM, Grubhub, box, Spotify, and a lot more companies use it. Get Started with Docker with this amazing open-source site that can get you on your feet:

the official docs are also a good place to start!: https://docs.docker.com/

Conlusion

If you've used Docker or Kubernetes flaunt it, if not just learn it. You will thank me later.

My Misconception when Learning Web Dev

Lohit Aryan — Tue, 16 Jun 2020 03:02:01 +0000

Misconception

I got ready for starting my summer project which was a boilerplate for NodeJS apps. I had only finished a few courses and online tutorials on node with express routing and login features using PassportJS. It took me a while to navigate through all the docs and stackoverflow to finally finish the app and I thought gained a lot of knowledge on making and deploying a proper app, I was already celebrating that I was now intermediate level profecient in JS.

Realization

I was interviewing for a web dev internship. I was really excited since I was confident in what I knew. He started of basic with some troubleshooting questions, asking about myself and my projects etc. now he asked me another pretty basic question: I enter a email into a textfeild and submit it, how do check if its valid on the backend? pretty general but looking back to my project I just used a dependency and called a function to check its validity in a controller .js file I had no idea how the check actually works. I assumed its a simple loop to check for the @ and get info after that and told my interviewer the same. Well turns out that answer was not even close to being right.

The answer the interviewer was expecting was using regex to check the pattern which will give us a result faster and told me that looping is actually not efficient nor usable at all.

Then it hit me hard, the misconception that I knew making a nodejs app which in reality I had no idea HOW my code does what its doing. I knew I could just import a dependency for validation, sanitization and other features but did I know HOW they work? the simple answer was nope.

Conclusion

Always learn HOW the language/framework/dependency works and not just calling it. Even a college freshman can search up code copy paste it and learn it a bit to make it work but I want everyone to realize from my experience that you might be missing the most important and fun part of learning!

Do you "Really" know JavaScript?

Lohit Aryan — Sun, 18 Aug 2019 12:52:18 +0000

JavaScript?

JavaScript is one of the biggest growing programming languages to code on the web. But do you really know JavaScript?

For Example:

var a = "42";
var b = 42; 
a == b;         // true
a === b;        // false

Wondering why? or for some who might now, have you wondered how much you don't know about JavaScript.

Most People will be shocked too see how useful it can be to learn more about plain JavaScript/ES6+. Yes, even if your using a big time JS framework like Node or React its gonna be a waste without good foundation of the basics.

Object Destructing, Generators, this object; async , parallel, and concurrent functions

and the List goes on, these are only the basics. If you wanna up your JS game then Go BACK TO THE FOUNDATION , give YDKJS (its a free ebook repo) a read and there are many more resources to know about and also go deep into ES6 and the latest features JS is always updated to make your life better no harm in knowing how.

Conclusion

JavaScript is always evolving and faster then you can think of, keep looking into these new features and how they improve performance and not just for info but to know what all your JS code means and how you can improve on it!

Now the future of static sites?

Check it Out! and Lemme know any design ideas I can add, in the comments.

When thinking about NextJS and now you need to remember some keywords:

Static Site, Serverless, Code Splitting.

These are the Super Powers you will get. Building these using Webpack or other frameworks can eat up a whole lot of your time.

Static sites are a lot faster than dynamic sites but harder to change. NextJS will only build your site statically while the rest can be dynamic if you want. Its pretty amazing in terms of speed.

You know when a website takes a while to load and you see a big white screen for a while. Agh :( its horrible.
