If you want to be good in data science, you cannot underestimate data analytics and statistics. Both hate guessing and they both love facts. If you are knowledgeable in data analytics and statistics, you will be able to think critically and most of all make data-driven decisions. In this article, we are going to review the basic statistical terms every data scientist should be familiar with.

The first thing you probably did is google search “what skills do I need to become a data scientist” phrase. And what did you get? You were faced with a relatively long list of skills required to become a data scientist, ranging from technical to nontechnical skills – from statistics to programming in Python and R, up to storytelling skills and making presentations. But who has all these skills? The good news is probably nobody. The fact is that two data scientists do have a sharable foundation of knowledge, nevertheless, each of them has their own narrow specialty, which is sometimes so deep that they couldn’t switch their jobs. One data scientist’s job could be close to a job of a statistician’s, while another could be an expert in Python. But, if you want to start with data science, where do you begin? Do you really have to be an expert in Phyton? Should your knowledge of statistical analytics be so deep? The fact is that data scientists have a diverse skill set that is usually not found in a single individual.
In this article, we are going to take a look at nontechnical and technical skills that are required (or at least some of them) to become a data scientist.

If you are a complete scraping beginner, this article is for you. If not, move on, because we are going to learn about scraping and parsing, but without using regular expressions or any supporting libraries. Moreover, we will do it using basic PHP string functions. Sure, PHP is not the best language choice for scrapping and parsing but it’s easy to learn and comprehend so it is a good candidate for beginners. First, we are going to explain what parsing is. Then, we are going to have a look at arrays, the GET method, stream_context_create and file_get_contents functions. Afterward, we are going to apply the strpos and substr functions, and at the end of this mini-project, we are going to display the results using print_r function.
Roll your sleeves PHP beginner, we are diving in.

In this article, we are going to learn the difference between crawling, scraping, and parsing in computer science. Sometimes these expressions are used interchangeably, but they are definitely not synonyms. Usually, crawling is the process that comes first – it is about following internal and external links, then comes scraping, which is about extracting bits of data that resulted from crawling, and then at the end comes parsing, which is all about breaking that data into specific, meaningful parts. Nevertheless, let’s look into these terms in more detail.

Desktop apps, mobile apps, and web apps. Apps are everywhere. In the past years, as hardware became more powerful, the tendency to merge apps between desktop, mobile, and web platforms is higher than ever. And, in accordance with that, we meet more and more programming languages and frameworks that we can use on every platform with a minimal trade-off in terms of code difference, app execution speed, and even user interface.
In this article, we are going to answer the question of how to make a (mobile) app as a total beginner. The answer requires a multi-faceted approach, starting with the perspective of the person that is asking that question. Are you an aspiring developer who wants to learn how to develop an app? Are you an eager product manager? Or are you an ambitious startup owner?

The boolean logic is named after George Boole, who is the pioneer in the field of mathematical logic. At the very core of boolean logic is the idea that all values can be either true or false, and this has been translated into computer science as booleans – a logical data type that can only have two values, either true or false, on or off, yes or no, etc. In this article, we’re going to look into booleans basics, we will get to know the concept of falsy and truthy values, and at the end, we will get to know what boolean() object is all about.
