Key-value stores are essential and often used, especially in operations that require fast and frequent lookups. They allow an object - the key - to be mapped to another object, the value. This way, the values can easily be retrieved, by looking up the key. In Java, the most popular...

List concatenation the act of creating a single list from multiple smaller lists by daisy chaining them together. There are many ways of concatenating lists in Python. Specifically, in this article, we'll be going over how to concatenate two lists in Python using the plus operator, unpack operator, multiply operator,...
Oftentimes, we are faced with a situation where we need to split a string at some specific character or substring, to derive some useful information from it. For example, we might want to split a phone number on the country code or data imported from a CSV file. In this...
Lists are useful in different ways compared to other datatypes because of how versatile they are. In this article we'll take a look at one of the most common operations with lists - finding the index of an element. We will take a look at different scenarios of finding an...
Hoisting is a JavaScript behavior commonly known for making variables and functions available for use before the variable is assigned a value or the function is defined. In effect, it puts variable, function and class declarations to the top of their scope (the global scope or a function) before execution....
By default, when writing a Vue.js Single Page Application (SPA), all necessary assets such as JavaScript and CSS files are loaded together when the page is loaded. When dealing with large files, this can lead to unsatisfactory user experience. With the help of Webpack, it is possible to load...
Facial detection is a powerful and common use-case of Machine Learning. It can be used to automatize manual tasks such as school attendance and law enforcement. In the other hand, it can be used for biometric authorization. In this article, we'll perform facial detection in Python, using OpenCV. OpenCV OpenCV...
Redis is an in-memory data store, which can be used as a NoSQL database, cache, or as a typical message broker. It's written in ANSI C, which compiles into significantly efficient machine code and its ability to store data as key-value pairs makes in-memory caching an attractive use-case for Redis,...
If you are a Machine Learning Engineer, Data Scientist, or a hobbyist developing Machine Learning Models from time to time just for fun, then it is very likely that you are familiar with Tensorflow. Tensorflow is an open-source and free framework developed by Google Brain Team written in Python, C+...
