Trees are an important data structure, as they provide major advantages over other traditional data structures. A tree combines the advantages of an ordered array and a linked list:

• Search is fast for an ordered array, whereas insertion and deletion are fast in a linked list.
• But searching is slow in a linked list, and insertion and deletion are slow for an ordered array.

Let's start with two basic facts:

• Classical computers have enabled us to make amazing things. The best example is the Internet.
• There are still things that classical computing can’t do. The most common example is optimization — the process of finding the best solution among many solutions.

Let’s try to understand the problem of optimization:

I am a full-time Software Engineer and a part-time Writer and I decided to start learning day trading and in this story, I wanted to share some of the lessons I have learned and I wished somebody would have told me before I started day trading. I am sharing my learnings and experiences for educating you so that you don’t make the same mistakes as I did.

1. Start Small

Working on new projects is always super exciting — we have the freedom to design and architect the things any way we want. But this planning, when not done properly, can cause us a lot of pain in the future.

Choosing your app database is one of the critical decisions you’ll have to make, and with this article, I intend to introduce you to various database options — along with listing some pros and cons to help you make wiser database decisions.

Key–Value

Our database is structured just like a JSON object — every key is unique, and each key points…

Some mistakes which most newbies and even some experienced folks (like me) make while writing code and how you can avoid them.

0. Putting everything into one file

Heads-up, this article is not going to be a technical one where I will be complaining about people’s code and bad documentation for developer unhappiness. It’s about a problem which is much bigger, that we all will face in our dev careers, and here we will discuss some solutions as well.

I have broken this article into three parts, where the first part will help you understand the problem and the other two parts are about the solution to the problem.

Part 1. Understanding the Problem

A group of developers did an experiment with some randomly selected developers on GitHub, and they identified a list…

The aim of this article is to give a heads-up to all the developers out there so that they can build and plan better web apps, set them up for success, and help avoid some embarrassing issues I came across.

Note: As of November 2020, Flutter for the web is still in beta. After playing around with some POCs, I felt it was a fit for my application requirements, so I went ahead with it for production.

I initially wanted to use Firebase Realtime Database, but Google has surprisingly yet to build the plug-ins for Flutter web. …

To a certain extent, the projects on your resume will control what you will be going through in the interview.

If you have just any random cliche projects, the interviewer will bring out questions from their own books. But if you have some really interesting and valuable things to talk about based on what you have built, it will give you a lot more confidence and a clear edge over other candidates.

Some Myths to Bust Before We Get Started

1. You have to build a project that you are passionate about

You don’t have to build a project you are passionate about.

If you really are passionate about it, go for it, but it isn’t necessary to get you…
