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. Another day, I was pretty bored, and when I look back to my DVD collection, I found Inception, Matrix Reloaded, and The Social Network, this all movies are in some way related to computers and technology, which strike me the idea to publish my list of Top 10 Computer programming movies.
How HTTP Basic Authentication works in Spring Security?
In the last article, you have learned how to enable Http basic authentication in Spring security-based Java application, and now we'll go one step further to understand how exactly http basic authentication works in Spring security. If you remember, when you use HTTP Basic for authentication purposes, the client, like a browser or a rest client sends login credentials in the http request header. The header is aptly named "Authorization," and it contains a Base64 encoded string, which is created by concatenating username and password using a colon. For example, if the username is "johnsmith" and the password is "JOHN3214" then they will be concatenated as "johnsmith:JOHN3214" before encoded using base 64 encoding algorithms.
How to limit number of concurrent session in a Java web application using Spring Security? Example
If you don't know, Spring security can limit the number of sessions a user can have in a Java web application. If you are developing a web application especially a secure web application in Java JEE then you must have come up with the requirement similar to many online banking portals have like only one session per user at a time or no concurrent session per user. If the user tries to open a new session then either an alert is shown or his previous session is closed. Even though you can also implement this functionality without using spring security but with Spring security, it's just a piece of cake with coffee :).
2 Ways to setup LDAP Active Directory Authentication in Java - Spring Security Example Tutorial
The LDAP authentication is one of the most popular authentication mechanism around the world for enterprise application and Active directory (an LDAP implementation by Microsoft for Windows) is another widely used LDAP server. In many projects, we need to authenticate against active directory using LDAP by credentials provided in the login screen. Sometimes this simple task gets tricky because of various issues faced during implementation and integration and no standard way of doing LDAP authentication in a Java web application. Even though Java provides LDAP support but in this article, I will mostly talk about spring security because of it's my preferred Java framework for authentication, authorization, and security-related stuff.

SQL Self Join Example - SQL Query to Find Employees Earning More Than Managers - LeetCode Solution
Hello guys, are you looking for a simple example of how to use SELF JOIN in SQL? If yes, then you have come to the right place. This article will show you how to use Self join in solving interesting SQL problems from LeetCode. Along the way, you will also learn this useful SQL concept. So, what are you waiting for? Let's first check the problem, and then we'll write an SQL query using SELF Join to solve this problem.
Write an SQL Query to Find Employees Earning More Than Managers
The Employee table holds all employees, including their managers. Every employee has an Id, and there is also a column for the manager Id, as shown below:
+----+-------+--------+-----------+
| Id | Name | Salary | ManagerId |
+----+-------+--------+-----------+
| 1 | Joe | 70000 | 3 |
| 2 | Henry | 80000 | 4 |
| 3 | Sam | 60000 | NULL |
| 4 | Max | 90000 | NULL |
+----+-------+--------+-----------+
Given the Employee table, write a SQL query that finds employees who earn more than their managers. For the above table, Joe is the only employee who earns more than his manager because Henry's Manager is Max, who earns 90000, which is more than Henry's salary of 80000.

Difference between row_number(), rank() and dense_rank() window functions in SQL
Though all three are ranking functions in SQL, also known as a window function in Microsoft SQL Server, the difference between rank(), dense_rank(), and row_number() comes when you have ties on ranking i.e. duplicate records. For example, if you are ranking employees by their salaries then what would be the rank of two employees of the same salaries? It depends on which ranking function you are using like row_number, rank, or dense_rank.
Top 6 Books to Learn and Master Programming and Coding - Must Read, Best of Lot
Coding is an integral part of Programming, and we all somehow learned to code by following examples here and there. Yes, I am talking about both self-taught programmer and Computer Science Graduates. You can learn Coding easily if you are dedicated, but what is more difficult is to write good code. You can easily find programmers in Java, C++, Ruby, or Python, but finding programmers, who are also a good coder is very difficult. Some universities have a good curriculum and practical classes to teach coding better than others, but most of these great coders are self-taught Programmers, who learned by reading books, joining online courses, and doing things on their own.

This move from Pivotal 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 5 or Spring Professional 5 (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.
How to Sort an HashMap by values in Java 8 - Example Tutorial
In the last article, I have shown you how to sort a Map in Java 8 by keys, and today, I'll teach you how to sort a Map by values using Java 8 features e.g. lambda expression, method reference, streams, and new methods added into the java.util.Comparator and Map.Entry classes. In order to sort any Map, like HashMap, Hashtable, LinkedHashMap, TreemMap, or even ConcurrentHashMap, you can first get a set of entries by using the entrySet() method and then you can get the stream by calling the stream() method. The entrySet() method returns a Set which inherit the stream() method from the java.util.Collection class. Once you got the stream, you can just call the sorted() method which can sort all Map.Entry objects available in Stream using a Comparator.

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 5 Books to Learn SQL and Database Design for Programmers and DBAs - Best of Lot
The database design and modeling are one of those topics which rarely get the attention they deserve, especially at the start of the project, but once things have gone out of hand, then everybody talks about them. Comments like - this database is designed poorly, the schema is not performing well, you cannot add a new column easily, etc. becomes very common. The most problem with database design is that it is mainly done by application developers like Java or C++ developer who knows SQL, but they are not the expert on how to design tables and schema. The Database admins or DBAs know database and SQL better than application programmers, but they mostly focus on the admin part of the database, preferably on application part like designing tables and relations between them, which is left to the application developer.

Top 5 books to learn Agile and Scrum for Programmers - Best of lot, Must Read
When I started my career, it was all waterfall model. You try, fail, and then with every version you get an improved version of the software. I pretty much used to this model of software development until I was introduced to Agile development methodologies in my next company. I was confused about Agile as some people say its Scrum and Sprint, other ways its XP and Kanban, etc. The confusion lasted for a long time because I was afraid of asking questions (afraid of being perceived as dumb and someone who wastes time on meetings) and only getting information in bits and pieces and I wasn't good at searching books at that time. From that experience, I learned that, when you have confusion and want to learn more about new technology, nothing is better than a book or online training courses to start with.

Top 5 C++ Programming Books - Must Read, Best of Lot
Hello guys, I have started my programming career with C and C++ before learning Java, and it's been more than 11 years since I am using C++, though not as often as Java, which becomes my primary skill, my C++ knowledge has helped me to work on projects where both C++ and Java is used. Often time, I am rusty with C++ with very less coding, but whenever I have to refresh my knowledge, I have the right books to do so. I have used C++ on both professional and personal projects and mostly use a GCC compiler. If you ask me which one is tough to learn, C++ or Java? I would say C++? It's even difficult to master, and you cannot master it unless your coding C++ daily.
