We can define parallel programming by saying that it is a way to make the execution of a calculation faster by creating several threads which will run on different cores (consider single thread per one core). First let us understand the speedup/acceleration. Amdahl’s law established the notion of speedup. The…

The acks you get from the message broker — Messaging is just another request-response call to a broker Last time, we discussed about the risk of duplicate database records due to the request-response nature of the DB protocol. Messaging, at first glance, is a different beast: you don’t wait to get a reply before moving on. As a matter of fact, you are typically not expecting a reply…

The acks you get from other APIs — The tri-state boolean As we all know, booleans can have three values: true, false, or file-not-found. The Ack problem forces us to reconsider what are the possible outcome of any API call. Looking at a typical REST call: The request was performed: any 2xx or 3xx reply; The request was denied and hence…

Pre-Requisites Understanding of bytes, hexadecimal & bit shifting Familiarity with Python Introduction In what order/arrangement are multi-byte data stored in computer memory? Based on this order, how is such data interpreted and computed to a specific value? Endianness provides the answers. Endianness applies to multi-byte data, with no ordering required for single-byte data…

Hi! I am Disha Jaisingpure, and I want to share my journey — from being a lost, non-technical student to a passionate, high-scoring computer learner with Comp-Pro Infotech. I was in 8th class when I had to choose my third group subject for 9th and 10th. We had an array…

I LOVE introspection in Julia; here are some useful methods! — introduction Julia is a language with a lot of perks. Though the language is young, it has a thriving ecosystem boasting over 9,000 packages ranging in application from biological sciences to web-development. There are a lot of really cool things to love about Julia. From multiple dispatch to constructors, the language…

To make sense of C++, think of it as a merging of more sublanguages — Item 1: View C++ as a federation of languages. Effective C++, Scott Meyers, 2005. C++ is a rich programming language. It supports various programming styles and language features. Unfortunately, this abundance can be daunting in its sheer size. Reading two different pieces of code written in C++, we can get the…

If you are learning how to code, chances are you have used data structures to store and organize your data. Data structures are necessary for web development to perform a variety of operations such as keeping track of user login information or product details for items on sale. The very…

I just finished my first month as a Software Developer Intern (I work at a pretty cool MedTech company) and after binging too many “How to survive at your summer internship” videos… I decided they’re just glorified “Day in the Life” videos. If you’re here you’re probably like me so…
