Top 10 Computer Programming, Artificial Intelligence, and Sci-Fi Movies for Programmers and Tech geeks

Hello guys, being a computer programmer, I love movies that are based on programmers' life, work, and concept. Thankfully Hollywood is no short of films based on computers, programming, and geeky technical stuff.

How to Crack Spring Professional Develop (2V0-72.22) Exam - Latest Spring Certification for Java Programmers

Ever since VmWare, the company behind the Spring framework made the mandatory Spring training optional (see here), I have received many queries from experienced Java developers who are interested in doing Spring certifications. This move from VmWare has suddenly made the Spring certification affordable for many experienced Java and Spring developers who were interested in Spring certification earlier but couldn't progress further due to expensive mandatory training. Since many of them are now preparing for Spring certifications like Spring Core  or Spring Professional (VMware EDU-1202) via self-study they are increasingly looking for good resources to prepare for the exam. I have received a lot of questions on preparation, books, mock exams, exam structure, passing marks, and useful resources.

Top 10 Advanced C++ (CPP) Books for Experienced Developers - Must Read

Once you know C++ and spends a couple of years of programming in C++, you started to feel that you know the basics and have good command over C++ programming. At this time, the programmer goes to two paths, one who chose to do just fire-fighting and daily work and never upgraded or forced to learn new or more by reading books, participating in forums, and giving presentations. The other group of programmers explores new books to learn C++ in detail and after reading a couple of books on this list, they also realize how much of C++ they know is incomplete and incorrect. That's why I recommend experienced C++ developers to read books to complete the journey from a junior developer to a senior developer.

Top 3 Books to Learn TCP/IP, UDP and Computer Networking Protocols - Best of Lot

Both TCP/IP and UDP are very popular networking protocol and in this era of the internet and a connected world, they become even more important. No matter, whether you are a computer science graduate or doing masters in computer science, a software engineer, a network engineer, or a Java programmer, good knowledge of TCP/IP and UDP goes a long way to securing a job and doing well on it. Even though I mostly interview for Java programmers, I almost always ask a couple of questions on TCP/IP and UDP protocol to check if the candidate is familiar with computer network basics or not because even if you work for Java application, you are exposed to the network.

Top 5 Soft Skill and Career Development Books and Courses for Programmers

Most of the software developers, programmers, and coders spend a considerable amount of their time and energy on learning technologies which get obsolete in few years like a new framework or a new programming language but they neglect something more important like soft skills. Unlike technical stuff, soft skills will not only serve you good in your job and career but also in your life and it won't get obsolete as quickly as the new web application development framework you have just learned. Similarly, most of us put a lot of effort to get a job but after that, we don't put much effort to grow on that job, the result is many programmers and software developers stuck in their careers.

Top 10 Advanced Java books for Intermediate and Experienced Developers

Hello guys, once you learn Java and done with reading some of the best known introductory books on Java and have a couple of years of experience under your belt, you would be hungry to transition from an intermediate Java developer to an expert Java programmer, also known as Java guru. This transition is not smooth, and I have seen many Java developers having 2 to 6 years of experience stuck where they are and have absolutely no knowledge of advanced topics like JVM internals, Concurrency, Garbage collection, and Performance tuning.

Top 5 Books to learn UML (Unified Modeling Language) for Java Developers - Best of Lot, Must Read

The UML stands for Unified Modelling language and it is one of the great tools for Object-oriented design. It allows you to create several diagrams like class diagram, sequence diagram, object diagram, etc, which helps you to understand your system better.  The UML also helps you to convey your thoughts and design to peers and team members before implementation. Since a picture is worth a thousand words, those interactions often help you to find shortcomings and loopholes in your software design very early. That's actually the reason I use UML in our projects. Btw, I didn't know about UML or UML diagrams when I first started Java development.
