Top 10 UNIX and Linux System Programming Books- Best of Lot, Must Read

I have been sharing programming books in this blog for a long time, starting with core Java; I moved to other related technology, like Spring, Design patterns, Data Structure and Algorithms, etc. Today, I am going to share some of the best UNIX and Linux programming books. The list contains some of the must-read UNIX books from great writers like Sir Richard. Stevens, Sir Brain Kernighan, who has contributed so much to the development of the UNIX operating system. Most of the books on this list are timeless,  classic, and don't age with time, much like UNIX, which is around for the last 40 years, and I am sure it will be around for the next 40 years, or maybe forever.

Top 5 Books to Learn Scala and Functional Programming - Best of Lot

Scala is one of the relatively new programming languages which encompasses best practices of many programming languages. The biggest strength of Scala is that it provides a beautiful blend of object-oriented programming and Functional programming. So, you can not only construct elegant class hierarchies for maximum code reuse and extensibility, but you can also implement their behavior using higher-order functions. It has a concise syntax with less ceremony, which also makes it ideal for scripting but doesn't underestimate its power. Like Java, Scala has also used for mission-critical applications by technical giants like Twitter, LinkedIn, and Intel.

How to Enroll on Spring Professional Certification (VMware EDU-1202) and Schedule Exam

So, you have been preparing for Spring certification for quite a sometime, and now you feel you are ready to take the exam, and it's time to buy the Spring certification voucher and schedule your exam. In this article, I'll show you how to buy the Spring certification voucher online. But, before purchasing a voucher, I would like to remind you that the Spring certification (VMware EDU-1202) voucher is only valid for 90 days, after that it will expire.

Do you Need to Pass OCAJP before taking OCPJP - Core Java Certification from Oracle

Even though we now have Java 11 certification, I know many Java developers who are going for Java certification like Java SE 8 Programmer 1 and 2, also known as OCAJP 8 and OCPJP 8 with exam code 1Z0-808 and 1Z0-809. Even though Oracle split Java certification into 2 after acquiring Sun Microsystem in 2010, there is still confusion among Java developers whether they need to pass just one OCAJP exam or both OCAJP and OCPJP exam to become a certified Java developer. Well, The short answer is Yes, if you want to become a Java certified engineer then you need to pass both OCAJP and OCPJP, but the long answer depends upon your situation, e.g. whether you hold any previous Java certification or not, which we'll discuss in the second section.
