C++, Getting Started with the Basics: Working with Dependencies and Linker

IntroTaking a Library Dependency inside Our Own C++ CodeSetting up the Build PipelineBack to Basics: Compilation of a C++ ProgramPreprocessing the HeadersLinkingResourcesIntro

As I mentioned in my previous post about C++, I am learning C++. It has been a bumpy ride so far, and C++ is certainly not an easy to pick up programming language! So, I thought what better way to make the learning stronger than blogging about my journey and pinning down my experience. You now know ...

I am probably the least qualified person to be writing a blog post about C++. So, please approach this post with some caution.But, why am I writing it then? Well, I am currently learning C++, and it has been an unusual experience compared to my other programming-language-learning journeys.At this stage, my assumption is that the main difference that causes me to struggle comes from the fact that:

Last week, I have moved all my personal compute and storage from Azure to AWS. I took this opportunity as an excuse to also start to manage all that infrastructure through Terraform. Why AWS though? I had the chance to use AWS before on and off, but since I joined Deliver...

Redis Cluster - Benefits of Sharding and How It Works

The Problem
Redis Cluster: Enter

Key Distribution
Hash Tags: Getting back into control of your sharding strategy
Redirection
Distributing Reads

Conclusion

Redis is by far one of the most frequently used data stores. It's fascinating how much our our software-developer-minds go to Redis when we are faced with a data storage problem that requires some level of scale. Even if this might make us feel guilty, I have a somewhat confident assumption that this's the case...

Working with Slices in Go (Golang) - Understanding How append, copy and Slice Expressions Work

Introduction
How Slices Work
How append and copy Works
How Slice Expressions Work
⚠️ Modifying a Sliced-slice Modifies the Original Slice
⚠️ Calling append on a Sliced-slice May Modify the Original Slice

Introduction

Go programming language has two fundamental types at the language level to enable working with numbered sequence of elements: array and slice. At the syntax level, they may look like the same but they are fundamentally very different in terms of their behavior. The m...

Implementing OrderedMap in Go 2.0 by Using Generics with Delete Operation in O(1) Time Complexity

Probably the most sought after feature of Go programming language, Generics, is on its way and is expected to land with v2. You can check out the proposal here, and have a play with it in Go playground for v2. I stumbled upon rocketlaunchr.cloud's great post on using generics in Go 2, and the post shows how you can implement ordered maps. The post is very informative, and shows you how powerful Generics will be for Go.

However, I noticed a performance issues with the implementation of Delet...

Usage of the Heap Data Structure in Go (Golang), with Examples

So, Tell Me More About This Heap Data Structure

Heap is one of the most powerful data structures that is in our disposal to solve various real world problems more efficiently. Heap data structure usually comes with two shapes: Min Heap or Max Heap, and depending on which one it is, heap will give you efficient (i.e. O(1)) access to min/max value within the given collection.

Here is the characteristics of the heap data structure, which separate it from other data structure when all of these...
