As I was studying Operating Systems, I learned about multithreaded applications and how they work. I was pleasantly surprised to see that they got their own design patterns. As the guy with around 9 articles on different design patterns, I just had to write something about it. Well here goes
> “Legacy Code is code without tests” That's pretty much the premise of the whole book. Thanks for reading... Just kidding, there's a lot more to this. Testing is one of those things that I've ignored for a good portion of my career but
In our last article, I introduced the concepts of threads. We learned what threads are and how do they speed up our code. You can check out the previous article here: What are threads?Most, if not all modern operating systems support multiprocessing and at the same time processes can
Most, if not all modern operating systems support multiprocessing and at the same time processes can be run in multiple threads hence the word multithreading. This will give you a significant increase in performance and scalability but it comes with a price. The overall complexity of the code increases and
I've been programming professionally for almost 3 years. But I'm gonna be honest with you. My computer science (CS) skills are pretty lacking. That's why I've dedicated 2022 to finally learn some core computer science concepts. But where do I start? That&
Got slow python code? Don't want to refactor to some other "low-level" language? Want to impress your peers? We got all that here!! -------------------------------------------------------------------------------- Now that you are actually here, today we will cover ways to optimize our Python code specifically using Multithreading and asyncio. In
One of my goals in 2022 was to dive deeper into core computer science subjects. The first subject in the list is Operating Systems. This is a very wide subject but for simplicity sake, we will cover the basics. Today you will learn: * What is an operating system? * Different kinds
In October of 2020, I've published my first blog post about SOLID principles. This was the first written content I've ever put out on the internet. At the time, I and many of my friends thought it was a pretty stupid thing. There are already dozens,
This past week I've dropped all the typical backend engineering I usually do and did some game development. It was a fascinating experience, it's like I've gotten back the joy of programming. Ever since I've started working professionally programming became more of
As API developers it's easy for us to fall into the trap of routine. I'm not saying it's a bad thing but it gets boring real quick. To break through this routine it's up to us to do interesting and new things.
This is an awkward post. Most of my last articles have been directly correlated with Python and Django. But it may surprise you that I am NOT a "python" developer per see. I didn't pick Python, it chose me. God, that sounds cringe, but anyways I&
A couple of days ago I've started to see the word "web3" a lot. It started on Twitter but eventually spread to YouTube and I've succumbed to it. I've fallen down the web3 rabbit hole. Thankfully I'm out of it
Cacheing is one of those things that are simple at first but can get really messy quick. There's even a quote about it. > There are only two hard things in Computer Science: cache invalidation and naming things – Phil Karlton The story goes like this. 1. You start
Deployment is hard. You have to make sure that you are in the correct environment, with the correct variables, and finally, run the correct commands in order. Other things are hard too, like keeping code quality high with consistent testing, and linting. These kinds of things should be done automatically.
Some tasks don't have to be done immediately. Examples of tasks like these include: * When a user signs up, you don't need to immediately send emails to him. * When a video gets uploaded to YouTube, thumbnails get generated after some time. * When you want to generate
A couple of months I started my first project with Auth0. We had a RESTful application, and my team lead went and told me to integrate our authentication system with Auth0. I was confused because most of the work was done in the front end, and I just didn'
