Tutorial level: Beginner/Junior

Motivation

Sometimes, when we surf dribbble, uplabs and similar design clouds, we often find many concepts or prototypes with animations, micro interactions, application flow and so on.
I often find illustrations of mobile apps that are good and interesting, but of course they are still in the form of concept, so therefore, why don't we try to apply them as an interface for applications that we will build next.

Original concept

In the Dribbble Challenge we will try to build an interface for Coffee Ordering, as I found on Dribble.

A linked list is a linear data structure, which contains node structure and each node contains two elements. A data part that stores the value at that node and next part that stores the link to the next node as shown in the below image:

The first node also known as HEAD is usually used to traverse through the linked list. The last node (next part of the last node) points to NULL. The list can be visualized as a chain of nodes, where every node points to the next node.

Implementation of Singly Linked List

Representation:

In PHP, singly linked list can be represented as a class and a Node as a separate class. The LinkedList class contains a reference of Node class type.

//node structure
class Node {
  public $data;
  public $next;
}

class LinkedList {
  public $head;

  //constructor to create an empty LinkedList
  public function __construct(){
    $this->head = null;
  }
};

Artificial Intelligence or AI has gone far beyond its beginning and self-driving cars, virtual assistants, Google Lens, and personalized marketing, are some of the initial powerful applications of AI. The present generation is yet to witness the true potential of AI in the years to come. Companies are investing huge amounts of money to leverage the power of AI and build applications that offer best-in-class solutions to real-world problems.

Broadly speaking, AI is one of the powerful fields of computer science which focuses on making machines capable of mimicking human actions. Such machines are not explicitly programmed and it learns from past experiences to make decisions quite similar to what humans do through their brain. When one starts exploring AI, it is inevitable to come across its subset i.e. Machine Learning. Further deep learning is a subset of machine learning.

Brief

People who use Kibana in our company have different background — some of them are technical who process data, some are managers who simply want to monitor some KPIs. And all have various questions. In spite of Kibana is rather popular in IT companies, there are not many articles or courses about it. To fill the gap I have created Kibana Tips & Tricks — weekly letters with frequently asked questions or themes. Such letters help our users to become more familiar with Kibana. There are no secrets — just detailed description of how you may work with your data.

When you start learning a programming language(or just programming in general), usually there are first few chapters in books that introduce us such thing like data types (or just types). And we don't focus on this subject as much as we should because it's so simple, right? Well… I think that there is one little detail which can lead to big mistakes of understanding what really data type is.

Deadlocks

Thousands of new online businesses created daily. Dozens of different platforms work like real mega plants to meet the needs of humanity. In recent years, the Shopify occupies a leading position in the market and continues to gain momentum. Shopify's functionality is expanding rapidly, but sometimes even it's not enough. We want to show how you can integrate the accounting Netvisor to your newly made e-shop and what benefits you get at it.

Based on practice, even the simplest data analysis can lead to a significant reduction in CPA. Advertising campaigns on Facebook are no exceptions and need to be optimized over time. Often under optimization, you can see experiments with different types of audiences and targeting. If you want to get more conversions within the same budget, then you should pay attention to a few crucial points that we will consider in this article.

Ruby programmers around the world are participating in an increasing number of conferences where they gather to share reports on unfinished projects, discuss the future of Ruby, and welcome newcomers to the community. At such conferences, new ideas are born and a lot of inspiration comes for real masters of their craft. Let's take a look at the list of the main events of the Ruby community.
