Understanding the importance of async programming — When we start off with creating a web application, we don’t care about how performant it is (and we shouldn’t to be honest). Our aim is to get a basic POC done and see if it gets some audience. This approach fits well until your user base grows beyond a…

A peek into the world of database locks, their types, and issues associated — Concurrency control should become a familiar term if you are dealing with locks. In a large application accessed by thousands of users, concurrency is inevitable. Your application should be able to handle multiple requests simultaneously.

Bash is a very important tool that programmers ignore most of the time. Git is another topic that programmers miss out on, and I have covered it in one of my newsletter posts. Another topic I would love to cover in my future posts is How to document your codebase…

Coding is fun, but deployment can take the fun out of it! Before cloud architecture gained traction, owning and borrowing servers used to be a very common strategy. Over the period of time managing own servers became a real issue. Many people dreamt of building an application and hosting it…

I love talking about asynchronicity quite a lot. The concept of asynchronicity, where things are executed flawlessly, is quite fascinating to me. We can be more efficient and get more things done this way. Async is a way of life! Coming back to technology. Have you heard of the C10k…

Understand why there are new kinds of databases coming out — When I started my programming journey, I learned many languages like Python and web frameworks like Django quite in-depth. I didn’t care much about databases and how they store information or why they have certain design patterns. But over period of time, I have realized that it’s quite important to…

I am a big fan of Safari when it comes to web browsers. It has almost everything I desire in a browser. But after the latest update of Safari and the introduction of the amazing tab group feature (no other browser has done it better than Safari, trust me), Safari…
