A hidden gem

Bitcoin bull run is in full force. Bitcoin was near $3,000 after the March Corona-crash that took down Stonks, Crypto and Gold with it and now I chuckle when I write this — Bitcoin is at $57,000. It’s not the first time we have seen Bitcoin surge past all odds. The same happened in 2013 and 2017 but what’s different this time is that we have corporate America behind us. From tech firms and hedge funds to even insurance firms and the Mayor of Miami!

I’m certain that Bitcoin hasn’t neared it’s “blow-off top” for this cycle but most of…


The Next Big Investment

Tesla stock for me has been a gift that keeps on giving. I have made some great profits on it and I’m sure if I continue to hold Tesla stock at its current price, I will still make significant profits over the next few years. Tesla is an amazing company with a visionary chief in charge — Elon Musk. If an election for humanity’s president comes along; I will vote for him. I am of course bullish on Tesla. Yet I sold all my Tesla stock. I also sold all my other stocks. I did not have a very diversified…


Should you buy or sell?

Anyone in the crypto space who’s not been living under a rock and ignoring the whole DeFi hype will know Uniswap. But what if you are that caveman hiding in your cave warming yourself with your bitcoin burns? Don’t worry I got you:

Uniswap is a decentralized exchange where users can swap any token that uses the famous ERC-20 protocol, used by Ethereum, USDT, Dai, AAVE, Binance coin etc. Uniswap makes it super easy to swap an ERC-20 token with another ERC-20 token with a few clicks by connecting your Metamask wallet to the exchange.

Sending emails to users is becoming an increasingly popular feature. Social media influencers are amassing their own email lists for future product sales and brands are doing the same to ensure they can stay in touch with their users and maintain brand awareness. There are many SaaS companies being created to help people automate email sending. However, they do cost a pretty penny for very little work.

If you are a developer with basic skills in Node.js or Python, why not leverage AWS to create this from the ground up fairly quickly?

The use case for an email server is…


A harrowing personal story

This memory is fresh to write about. It’s almost too fresh… I can still feel the burn of missed out profits simply because of impatience. As uncomfortable as it is, it would be too stupid to not write about it and force myself to analyse my mistakes and hopefully learn from it. Perhaps you can also learn from my mistake and not mess up the same way I did not too long ago.

“To invest successfully over a lifetime does not require a stratospheric IQ, unusual business insights, or inside information. What’s needed is a sound intellectual framework for making…


Be prepared if you’re interviewing at Amazon

The dreaded whiteboard coding interview. We all hate it, yet we all must face it.

It’s become the standard for companies to test a candidate’s programming prowess — especially for junior to mid roles. So, let’s sharpen up our skills and try one today.

Having spent time in several different countries, I’ve developed a strong network of friends in software-related roles in London, New Delhi, San Francisco, Chicago, Singapore, Berlin, and Munich.

On this occasion, I’m sharing something shared in my network — a question asked in an Amazon interview.

Don’t rush into a framework just yet

For anyone who is OCD/nit-picky about stuff, here’s a disclaimer: I know that definitionOf('framework') !== definitionOf('library') however for ease of use, in this article I will use the words “framework” and “library” interchangeably.

The internet is filled with sub-Reddits, Twitter conversations, Medium articles and YouTube videos about JavaScript frameworks. All major companies use some sort of a framework or JS library to build the views for their web applications. And because of React Native and NativeScript, sometimes even their mobile application views are built with a JS abstraction layer! Currently there are 3 main JavaScript libraries/frameworks; React, Vue and Angular…


Stop doing tutorials and start building something real. You’re ready

With the ubiquity of Udemy courses, YouTube tutorials, and Medium articles, the access to knowledge for a developer is amazing! This is what has enabled several self-taught developers to become full-time employees in the software industry or launch their own start-ups. However, the way a self-taught developer gains enough skills to earn a job or build their own project remains tedious. I taught myself programming and helped my brother and several friends on their journey, and I noticed that we all faced the same issue.

The lack of a formal structure from a college program has certain benefits but also…


Test your deployed React App every hour

We have a lot of ground to cover in this tutorial so let’s get straight to it!

Objective

To have a front end test for our website that’s run every hour and alerts us of any failure on Slack.

Creating the React App

Create a new React project withnpx create-react-app periodic-testing.

I made a small adjustment to App.js — it looks like this now:

Writing a Test

To add a test to our application, let’s use TestCafe, an end-to-end testing tool. Since we only need this library for testing, we can add it as a dev-dependency with npm i -D testcafe.

Here’s what our basic test looks…
