There is no doubt that JavaScript is the most popular programming language at this moment and it's also confirmed by StackOverFlow's 2018 Survey. You can build static websites, web applications, native mobile applications (yes you can do that too), desktop applications and even server-side application in
JavaScript. It also makes you hundred time more employer as there are tons of web development jobs out there. Becuase of that ore and more developers are learning JavaScript to become a web developer.

One of my goals in 2018 is to learn and master Git and I have been searching some good tutorials and courses to start with. The Internet is full of git tutorials and a simple Google search will leave you thousands of tutorials but the big question mark is where do you start? It's easy to pick a tutorial or a blog post if you have some background about what is Git, what it does? and how to use it but if you don't have much background then you need a course which can tell you all the information from the ground up. I personally like learning from a book or an online course before moving to blog posts as they were often well structured. When you search for Git courses in popular online course websites e.g. Udemy, Pluralsight or Coursera, you will find some good courses e.g.
Git Complete: The Definitive Guide on Udemy and
Git Fundamentals from Pluralsight which will teach you everything about Git step by step. These are excellent resources to start with Git.

In last summer, I had to work on a Java project which was using Oracle database at their backend. The project was a mix of Java code with Oracle PL/SQL stored procedures, where Stored procedures were quite big and complex to read. I had not worked on Oracle for a couple of years and almost forget whatever I knew before. So, to revise, update and re-learn and I looked over some of the books and online courses like
The Complete Oracle SQL Certification Course which helped me a lot. In my quest to revise and re-learn Oracle SQL, I also find lots of their used books on Oracle PL/SQL which are both interesting to read as well as provides a great wealth of information to any programmer.

If you are a Java developer and looking for some awesome resources e.g. books and courses to improve your multi-threading and concurrency skills in Java then you have come to the right place. In the past, I have shared
books and
tutorials on Java Concurrency and Multithreading and in this article, I am going to talk about some of the best free and paid course to learn multi-threading and concurrency in Java. You can join these free courses to improve your understanding of Java Concurrency and Multithreading. It's one of the most important skills for Java developers as almost all the companies who interviews Java developers pay particular attention to his knowledge and experience in this area.

A huge chunk of a developer's time is wasted in trying to repeat tasks and commands, especially when it comes to working with a bunch of UNIX or Linux machines and a good knowledge of shell scripting can free you from such mundane task and give time to do some interesting stuff. If you don't know what is shell scripting then let me tell you is nothing but a program written using shell built-ins and
Linux commands to automate things e.g. checking if a host is reachable or finding and deleting large files which are older than certain days or archiving them into another machine. Basically, it's a tool which allows you to automate boring and repeating task and that's the way programmers should work. They should not be repeating stuff, instead should be investing that time to create a script or program which can automate that task.

"Can a non-static method access a static variable or call a static method" is one of the frequently asked questions on
static modifier in Java, the answer is,
Yes, a non-static method can access a static variable or call a static method in Java. There is no problem with that because of static members i.e. both static variable and static methods belongs to a class and can be called from anywhere, depending upon their access modifier. For example, if a static variable is
private then it can only be accessed from the class itself, but you can access a public static variable from anywhere. Similarly, a private static method can be called from a non-static method of the same class but a public static method e.g.
main() can be called from anywhere.
