Top 5 Courses to Learn IntelliJIDEA and Android Studio IDE for Java Programmers in 2021 [Best & FREE]

There is no doubt that IntelliJ IDEA is THE best IDE for Java development, even though Eclipse may still be probably used by more people because it's FREE, IntelliJ IDEA is the most feature-rich and complete IDE. The Android Studio, which is the official IDE for Android development in Java, is also based upon IntelliJ IDEA, which further cement its place as the IDE Java developer should learn. The only thing which stops many other Java developers and me from moving from IntelliJ IDEA in the past was the lack of resources. Since Eclipse was free from the start, there are tons of resources, like books, courses, and tutorials are available. There are also a lot of resources to learn productivity tips, like keyboard shortcuts, and debugging techniques, but there were not many for Intelli IDEA.

5 Tips for Running SQL Queries on Production Database

Did you ever face a situation where some of your innocuous-looking action has caused production issues and that too big time? Well, I hope you have not because it's certainly, not a pleasant experience. One such innocuous-looking action is running SQL queries on production databases. I had that in the past very early in my career where I removed some config as duplicates only to find after a week that it stopped publishing messages to one of the downstream. When you work in complex systems that have so many components, millions of lines of code, thousands of configurations, and many databases with hundreds of tables, you have to be really careful with anything you do.

Top 5 Online Courses to learn gRPC and Google Protobuf in Java, Python, Go & C# in 2021

If you are a Java developer then you might have heard about the gPRC, the Google Remote Procedure Call solution. It's the latest buzz in the tech circle, and people are talking enthusiastically about it. The buzz is evident because it's coming from Google like Angular, Golang, Flutter, Dart, TensorFlow, and other latest technologies. For those who don't know, gRPC is a super-fast, super-efficient Remote Procedure Call (PRC) system that will help you to develop distributed systems like Microservices. This means you can use gPRC to communicate between your Microservices at super-fast speed.  Similar to other RPC solutions like SOAP, it allows a client application to call a method on the server as it is a local object. The server defines service and indicates that it can be called remotely with method parameter and return type and then provides implementation and an RPC server that can handle client calls.

Teachable, Thinkific vs Udemy? Which is Best Website for Beginners [2021]

I have been researching a lot about how to create a successful online course since last year. I have yet to launch my video course but I have started with some Udemy practice courses like my Spring certification practice test course on Udemy which has more than 1500+ students so far. I chose Udemy because they have a great platform for practice tests, but I am also learning other platforms like Teachable and Thinkific to create an online course website that is fully owned by me. Along the way, I have also started mentoring many readers about creating online courses and why they should create them. Why I am doing this? because I believe together we can learn better and succeed. If I have a group of passionate developers who like to teach online, there is a better chance of creating a successful online course.

Top 10 Eclipse Plugins for Java and Spring Boot Developers

There is no doubt that Eclipse is one of the most popular IDEs for Java development, and what makes Eclipse great is nothing but Plugins. There are hundreds of Eclipse plugins for different kinds of tasks and integration with other essential tools like there are plugins to download code from Github, SVN, CVS, etc. There are planning to use Maven or Gradle from Eclipse. There are specific plugins for Java development, Python Development, creating Spring-based Java applications,s and for creating Android apps from Eclipse itself. I have seen productivity improvement by just installing the right kind of plugins. For example, once you install the EGit plugin, you can manage your Git repository right from Eclipse. You will not need any other Git client. Similarly, adding Spring Tools plugins helps you to create Spring and Spring Boot based applications really easily.

Why Programmers & Software Engineers Should Create Online Courses in 2021

I often receive queries like should programmers create an alternative source of income, or should programmers create their own blog or website? Both are fundamental questions, and there was a time when I advise programmers to create their own blog, not just to learn and improve their understanding of the technology they know, but also to earn money while doing things you love, but time has changed. Now I advise Programmers and Software Developers to create and sell online courses on Teachable, ThinkificUdemy, or any other platforms. The reasons are still the same, you learn and earn, but the method has been changed. A blog is always an excellent way to establish yourself online, but it requires a lot more effort and time to earn something meaningful.

Difference between Dependency Injection and Factory Design Pattern in Java with Example

Learning a Programming language like Java or Python is easy, but writing production-quality code is difficult. Coding is as much art as the science behind it.

If you use them correctly, then they can express the intent of the code better and thus makes it easier to read and maintain.

Google Protocol Buffers (ProtoBuf) - Best Alternative to Java Serialization

If you have done some serialization works in Java, then you know that it's not that easy. Since the default serialization mechanism is not efficient and has a host of problems, see Effective Java Item 74 to 78, it's really not a good choice to persist Java object in production. Though many of the efficiency shortcomings of default Serialization can be mitigated by using a custom serialized format, they have their own encoding and parsing overhead. Google protocol buffers, popularly known as protobuf is an alternate and faster way to serialize Java objects. It's probably the best alternative to Java serialization and useful for both data storage and data transfer over the network.

Top 5 Online Courses to Learn Maven for Java Developers in 2021 - Best of Lot

The Apache Maven or commonly known as just "Maven," is an essential tool for Java Programmers. It allows you to build your project, manage dependencies, generate documentation, and a lot more. I can vouch for Maven's usefulness because I have come from the pre-Maven world of Software development, where you need to manage all the JAR files required by your project.

This can happen because of version mismatch like Spring needed a higher version of log4j than available in your project.
