An old programming language or a current trend in technology?

In a real-world setting, you often only have a small dataset to work with. Models trained on a small number of observations tend to overfit and produce inaccurate results. Learn how to avoid overfitting and get accurate predictions even if the available data is scarce. Big data and data science are concepts often heard together. It is believed that nowadays there are large amounts of data and that data science can draw valuable insights from all these terabytes of information.

If you search “will robots take my job” in your browser, you will find a website that lists the automation risk level for each occupation within two decades.

It’s sometimes hard to understand what IT people are talking about because of all the technical terms they throw around. So I compiled this little dictionary of IT terms for beginners! It may seem silly, but communication problems are all too common in IT teams. Programmers and other computer science professionals use a technical language of their own that may not be too accessible to non-technical people. But effective communication is one of the keys to survival in the industry, so it’s definitely worth understanding what those terms mean so you’re on the same page as everyone else.

Ever wondered what daily life in a tech company looks like but had no one to ask? Let’s take a look at a day on the IT team from the inside. All programmers wear plaid shirts and thick glasses, eat junk food, sleep during the day, stay awake all night, and spend their time in dark basements where the only light comes from a few monitors displaying tons of unintelligible code.

Being data-driven is a must for companies these days. If you think differently, you might as well pack it in now. Here’s why. Companies are always trying to outdistance each other, winning more clients and gaining the most profit. They burn a lot of time in building strategies and working on tactics, but their actions may not bring the expected results. Why not? Because they don’t start with data.

Technologies are constantly developing, and so is the labor market. Here are some tech jobs born in the 21st century.

Three years or three months? With all the 12-week bootcamps and coding schools out there, three years sound like a joke. “Enroll in our course today, and become an expert programmer!” “Start learning to code and jumpstart your programming career immediately!” Most probably, you’ve heard lots of claims like these if you’re interested in coding. Are they reassuring? Maybe. Frustrating? Sometimes. If you’ve been learning for a year and still feel like a newbie programmer while others are starting their careers in three months, you start to wonder: What’s wrong with me?

Why is June 21 the official start of summer? Let’s see how SQL can help us answer this question. The Summer Solstice Officially, June 21 is recognized as the summer solstice, the longest day of the entire year in terms of daylight. Why?

Data science professionals frequently coordinate their workloads, host meetings to discuss and share ideas, and collaborate to solve problems. But all it takes for things to fall apart is a lack of clear communication. Data Science is a team sport that involves a variety of professionals working together to solve technological problems.

The first steps are the hardest As a complete IT newbie, I had lots of doubts and fears about entering the IT industry.

As an ambitious database administrator, you want to get ahead of the crowd and expand your knowledge. The best way to do that is to get certified in the technology you’re working with. This article and infographic will guide you through the most popular database administrator certifications on the market today. If you’re here, you’re passionate about working with databases, like many other IT professionals. Being a database administrator (DBA) will open up an IT field of pure engineering, with little consideration of the business side of your organization.

Are you the type of database administrator who organizes files by folder? Do you have a folder full of sorted folders? If so, then scrum is the right methodology for you. A database administrator (DBA) is an essential member of any IT team. DBAs create, maintain, and secure an organization’s database, in addition to overseeing user rights assignment, backups, querying, and database tuning. You need specialized training and technical expertise to manage the specific RDBMS setup used by your organization (to understand what an RDBMS is, read on), along with a quirk for analytical thinking.

Within organizations, Scrum promotes efficient time and process management along with better team building and leadership. In order to implement Scrum, you’ll need to follow a few simple rules.

And yes, love is involved. Here at Vertabelo Academy, we’ve got some real OG programmers and data scientists making great content. They fell in love with data way before it was cool—and easy. So today, we’re jumping back in time to see what it was like to learn SQL before the Internet and Vertabelo Academy courses existed.

They say that if you do what you love, you’ll never work a day in your life. At Vertabelo Academy, we strongly believe in this adage. We’re creating courses because it’s what we enjoy doing. We’re passionate about SQL and data science, and we want to deliver the best content possible in these domains. To that end, we provide our users with practical modules because learning by doing is the best way to master a new skill.

Relational databases often store the value NULL in their tables. If you’re not familiar with NULL and what it is, you could run into unexpected problems. In this article, we’ll take a look at how the IN and EXISTS operators work with NULL. What Is NULL? In SQL, NULL is a special value indicating that a particular piece of data doesn’t exist in the database. For SQL beginners, it’s often a source of problems.

Phones, emails, social media accounts, and about a hundred other things are constantly competing for our attention. Can tech tools help us stay focused? A lot of apps say that they help humans work better and faster. But the truth is that the more interactive tools we use, the more focus-shattering notifications we get. In many ways, technology has gotten us into this problem. Can it help us get out of it?

Jane has a data problem and an overdue report. Will SQL save the day? Jane works as a business analyst for a large London bank. As she walks to the station on Monday morning, she’s thinking about last week’s unfinished work.

Here’s a shock: not everything in the movies is true. But these five documentaries offer interesting insights into the Internet and its people. Non-tech people tend to consider coding, hacking, and anything remotely dev-y as mysterious and magical processes. This myth is helped along by the movie industry, and there’s nothing wrong with that. Movie watchers generally like thrilling, action-packed stories, and coding can be anything but exciting. But not every good movie needs to be filled with action; some get our brains going by presenting new ideas or interesting viewpoints.

Learning from books is so 1999. Can app-based learning do any better? Do you like wasting your time? I don’t. Any time I start something, I find out how to do it efficiently. For me, this means learning new skills using apps and online learning rather than books. Online and app-based learning focuses on you, the student. This is the exact opposite of traditional learning, which is teacher-driven. There is a physical classroom and students, but the teacher plays the primary role.

Internet-based learning is very popular. Knowing your learning style and motivations will help you study smarter, not harder. We tend to spend a lot of time online these days. Between watching funny YouTube videos, catching up on news and celebrity gossip, and binge-watching our favorite Netflix series, we even find the time to learn new skills. But are we in a constant learning process? How can we pluck out – from the vast resources of the Internet – the exact courses and methods that will work for us (or you) personally?

The tech sector is experiencing strong job growth. Should SQL be on your list of must-have skills?

In today’s world, technology is evolving at an almost daily pace, and this is producing a flood of data that has to be managed.
