What Is Git And Why Should You Use It?

Git is a distributed source control system that is increasingly popular among software developers and teams. But what, exactly, IS Git, what does it do, and why is it such an excellent investment? Read on to find out! 

What Exactly is Git?

Git is a software tool that stores content – typically code – and tracks changes to that code over time, from various contributors. As a distributed version control system, Git maintains two repositories – remote and local. The remote repository is stored on a server, while the local repository is stored on every contributor’s computer. It uses this system to keep track of changes and coordinate those changes with features such as branches and merges, which we’ll discuss later. 

Benefits of Git in Software Development

You can see how Git is an extremely useful software, particularly for larger teams who might have dozens of developers working on different parts of a larger overall project, like a website or a mobile app. It has some key benefits for this sort of organization, as well:

Branching Capabilities

Git’s branching capabilities are arguably its biggest advantage. Unlike a centralized version control system, branching with Git is both cost-effective and simple to merge. The feature branch workflow is very popular among Git users for those reasons. With feature branches, you gain access to an isolated environment for every change to your codebase. When a developer is ready to work on something—no matter its size, they will create a new branch. This is to ensure the master branch will always have production quality code.

Deploying feature branches is more reliable than editing production code directly, and it also has organizational benefits. Feature branches allow you to represent development work at the same granularity as your agile backlog.

Performance

Git performs extremely well and reliably when you compare it to other version control systems. With Git, you can easily perform new code changes, version branches can be effortlessly compared and merged, while codes are optimized for improved performance.

Algorithms used to develop Git take full advantage of the deep knowledge that is stored within, including the use of attributes to create real source code file trees, how files get modified over time, and what kind of file access patterns are deployed to recall code files when a developer needs to.

Distributed Development

Git is not like Adobe SVN, where each developer gets a working copy pointing back to a single central repository. On the other hand, Git is a distributed version control system, and instead of a working copy, each developer has access to their own local repository stocked with a full history of commits.

This access to full local history allows Git to be fast because you no longer need a network connection in order to create commits, perform diffs between commits, or inspect prior file versions.


Distributed development has another advantage: making it easier to scale your engineering department. With SVN, if someone breaks the production branch, it affects other developers too because they won’t be able to check-in their changes until the break is fixed. When you use Git, there is no chance of running into such a block, and business will move on as usual as everybody continues working in their own local repositories and tending to their own business.

Lastly, distributed development creates a more reliable environment. Even if a developer destroys their own repository, they can simply clone another developer’s repository and start fresh.

Faster Release Cycle

Thanks to Git’s feature branches, enhanced distributed development, and high-performance, a faster release cycle is created. These capabilities help facilitate an agile workflow where developers are encouraged to share smaller changes more often. In turn, changes are able to be pushed down the deployment pipeline quicker than the monolithic releases we see commonly used with centralized version control systems.

Due to its fast release cycle, Git works extremely well with continuous integration and in continuous delivery environments. Git hooks enable you to run scripts when certain events happen inside a repository, allowing you to automate deployment as much as you choose to.

Install the Git Tools

Git is a distributed source control system with growing popularity among software developers. In this course, you will install the command line version of the Git client on your machine. You may be using a Windows, Mac, or Linux machine. In all cases, the installation and setup is fairly similar. You may wonder, “Why use the command line client of Git and not a graphical client?” That is a good question and one that we answer in this course. Additionally, you will have the opportunity to customize your command line interface and bookmark a few helpful sites. This course prepares you and your machine to get started using Git.

Everything You Need To Know About Building Progressive Web Apps with JavaScript

With the recent move to a more remote workforce and a connected device in nearly everyone’s pocket, the internet is more embedded in our lives than ever before. Websites have been around for decades, but how people use them has transformed. Now, there’s a new tool for how internet users access a business and learn about its features or services: Progressive Web Apps (PWAs).

If you run a business (or want to start one) that serves customers on the web, consider building a progressive web app. Even if you’re not a coder or developer, you can easily learn the skills required to build PWAs that offer an unrivaled experience to web users. The following beginner’s guide teaches you more about what progressive web apps are and how you can build them with JavaScript.

What Are Progressive Web Apps (PWAs)?

Progressive web apps are modern and tech-forward, built to behave like an app but run via a web browser. The major benefits of PWAs are that they are easy to access and have user-friendly capabilities. PWAs also offer an experience similar to a mobile app, even though users access them via a web browser (whether that browser is on a PC or a mobile device).

Progressive web apps have specific characteristics that make them worth the time required to build:

  • They are app-like. They behave like an app, so they are intuitive for users.
  • They are responsive. They work and look good no matter how a user accesses them.
  • They are linkable. Unlike apps that are more complicated to share, progressive web apps can be shared easily by simply sending a link.
  • They are discoverable. They can be optimized to show up in search results and other online directories.

Our online learning platform offers classes that will teach you the foundations of building a progressive web app.

Why Should You Use JavaScript?

You have many tool options when building progressive web apps. However, one of the best reasons to use JavaScript for progressive web apps is that you or your dev team likely already know it. According to Stack Overflow’s 2020 Developer Survey, JavaScript is the most commonly-used programming language – and has been for the past eight years! Rather than learn a new language to build your app, you can employ a tool you already know. Another benefit of using JavaScript to build a progressive web app is that you can quickly pass rich data through the Digital Object Model (DOM) layer. JavaScript is also an excellent choice for building and managing apps that will be used and accessed on various platforms — including many devices, browsers, and operating systems. If you don’t already have experience, it’s very easy to learn JavaScript, with our online courses. .

Why Security Awareness Is No Longer An Optional Skillset

In today’s track-everything digital world, it’s been said that data is worth more than oil or gold. Whether that’s entirely true is up for debate, but the fact is, people now share their personal information online like never before.

The price of not keeping personal information secure can be incredibly costly and stressful. At the personal level, it might mean we are more vulnerable to being scammed or having our details stolen by cybercriminals. At the enterprise level, it could put your entire company in jeopardy.

What Is Personal Information?

Basically, it covers any single piece of data that could identify you as an individual. Names are the most obvious, but it extends to things like date of birth, home address, telephone number and email. There are other forms of data that could also indirectly identify an individual. This sort of data includes things like IP address, location data, medical information and bank or financial data. These count as personal information too.

You might think this isn’t something that applies in your current role, but it does. Do you ever email or call a customer? If the answer is yes, then you are handling someone’s personal information. Learning the basics of security awareness will be helpful in your personal life, but also in your job!

How Much Personal Information Do We Share?

It’s difficult to overstate the sheer volume of data we share over the internet nowadays. Likewise, it’s a challenge to quantify it exactly. Perhaps the best way to think about it is to think about how much online storage some of the largest global corporations need. Much of that storage will be used to store and analyze their customers’ personal information.

Most recent estimates say that between Amazon, Facebook, Microsoft, and Google, at least 1,200PB (Petabytes) of data storage is used.To understand the scale of those storage needs, 1,200PB equals 1.2M TB (Terabytes). Your average laptop computer today comes with a 512GB hard drive – basically half of a terabyte. Frankly, it’s a staggering amount.

What Can I Do As An Individual?

There are a few steps individuals can take to keep their personal information as safe as possible. Most people are familiar with the concept of using strong unique passwords on accounts. Many people use two-factor identification, as well. It’s also prudent to be cautious about emails from unknown sources and to avoid giving out banking and credit card details except on trusted sites. Yet despite these steps to keep personal information secure, data breaches can and do happen to companies of all sizes. This results in large amounts of private customer data being made public. Large fines have been imposed on many well-known businesses for data breaches over the years, in addition to the negative impact on brand reputation and the amount of trust you have with your customers.

What Should My Company Do?

To increase security awareness in the workforce, the most common solution is training. Introductory training, intermediate training, and then some refresher training every year. Organizational security is only as strong as the weakest links in the workforce, so having employees with good security awareness is imperative. It’s business-critical that employees can recognise what might be an attempt to gain access to private information or a company’s internal network. It’s also important that employees know what steps to take if they believe there has been a data breach or potential cyber attack. 

As a professional in the workplace, working at pace and under pressure, making a simple security mistake can lead to an awful lot of problems. Since the number one gap in any IT security system is the people that use it, there are a lot of benefits to basic security awareness training.

How to Learn Excel: A Guide for Beginners

Posted by Develop Admin
March 9, 2021

Microsoft Excel is an application used extensively by businesses of all sizes to organize and manage their data. This powerful tool is part of the Microsoft Office suite of software and makes it easy for you to store your data, analyze it, and report on what your data is showing. For a beginner, Microsoft Excel can be intimidating or confusing, but once you understand the core concepts, it’s really easy to start using it in your job!

Getting Started: How To Create An Excel Spreadsheet

When you open Excel and create a blank spreadsheet, you’ll see that across the top, there are a series of horizontal columns that are labeled alphabetically and vertical rows that are numbered. The point (or cell) where a row and a column intersect will consist of both a number and a letter. For example, the box or cell in the top left corner is A1 – column A, row 1. Below that is A2 – column A, row 2, and to the right of the first cell is B1 – column B, row 2. These codes or names are known as cell references and are used to reference a specific point on the spreadsheet.

A "cell" in Microsoft Excel

To get started, place your cursor in the chosen cell, enter your data and then either click to a new cell, press “Enter”, or press “Tab” to move to the next cell. Next, take notice of the two boxes located above the lettered columns. Here, a box labeled the “name box” and a “formula bar” can be found. The “name box” will display the cell reference that is currently selected while the “formula bar” will allow users to enter functions and calculations.

Performing Calculations in Excel

To perform basic Excel calculations, you’ll need to enter the desired formula into the “formula bar.” To do this, it is crucial to begin each one with “=” or the equals sign. When you want to add together the sum of the data within two cell references, simply enter the formula into this bar. For example, if you want to add cells B1 and B2 and display the result in B3, you would put your cursor in B3 and then enter: “=B1+B2” into the formula bar and then click enter. Excel will automatically calculate the total and display it in cell B3

Using the Name box and Formula Bar in Microsoft Excel

To perform other calculations, use the following formulas:

  • To subtract: =B1-B2
  • To multiply: =B1*B2
  • To divide: =B1/B2

Using the Ribbon

The “ribbon” is simply a different way of referring to the main menu within Excel that is found at the top of the screen. This main menu (or ribbon) is where you can perform several different tasks related to your spreadsheet. You’ll see there are tabs labeled “File”, “Home”, “Insert”, “Page Layout”, “Formulas”, “Data”, “Review”, “View” and “Help”. Using these tabs to navigate, you can perform several different functions such as creating a new spreadsheet, reviewing data, or viewing a list of formulas. Also located on the ribbon are several tools that allow you to customize the way that the spreadsheet looks. You can change the font color or style, create bold or underlined text and change text alignment. You can also delete rows or columns of data or blank spaces within the ribbon.

The Ribbon in Microsoft Excel

Saving Spreadsheets

After a spreadsheet is completed, you can save your work by simply pressing the “ctrl” and “s” buttons at the same time, or by selecting “Save” under the “File” tab within the ribbon. Once the spreadsheet is saved, you can share your spreadsheets or just store them in a folder on your computer.

As you can see, while Microsoft Excel might be a bit intimidating at first, it’s actually pretty simple when you understand the core functionality. Knowing how to properly use Excel can help you stand out in your job and make you an invaluable member of your team, and we have a full suite of online courses to help you learn.
