  Launch Java process programmatically in Java

In some cases while working on some automation testcase, developers would like to launch Java process programmatically so that the tests can be ran without manual intervention. Java provides such methods to achieve this. ProcessBuilder can be used to build a Java process which can be launched when everything is ready. Basically it can take a list of parameters which are similar to the command line options/arguments.  For example, if you want to launch a Java process, you can do followi...

  PHP to get long running process progress dynamically

Frequently in web applications, we may have a request to the back end system which may trigger a long running process such as searching huge amount of data or a long running database process. Then the front end webpage may hang and wait for the process to be finished. During this process, if we can provide the user some information about the progress of the back end process, it may improve user experience. Unfortunately, in web applications, this seems not an easy task because web scripting lang...

  Linux Kernel is replacing HTTP link with HTTPS

Linux kernel is in the process of replacing the HTTP links in its source code with HTTPS links. HTTPS is considered more secure than HTTP and can prevent lots of attacks like Man-In-The-Middle attack.  Currently there are more than 150 patches submitted by Linux Kernel developers to replace these HTTP links.  One thing to be noted is this replacement process is not a manual search and replace process. Indeed, some scripts are created to find out these links and try to find whethe...

  Supervisord, God and Monit, which one to choose?

With the popularity of Docker, more and more service have been moved into docker containers and they are easy to build up and maintain for each atomic service(though it's a bit complex to maintain multiple docker containers which contain different service to form a complete solution). Ideally, each docker container should only contain one service which has only one running process. However, in reality there would be cases multiple processes would run in one single docker container and there is a...

  Why to opt for Hadoop?

Hadoop is a open source that stores and processes big data. The framework is written in Java for distributed processing and distributed storage of very large data. Hadoop is Scalable. It is a scalable platform because it stores and distributed large amount of data sets to hundreds and thousands of servers that operate in parallel. Traditional database systems cannot process large amount of data. But, hadoop enable business to run applications involving thousands of Terabyte data. Hadoop is ...

  Multithreading interview questions in Java

Multithreading as a widespread programming and execution model allows multiple threads to exist within the context of a single process. These threads share the process' resources but are able to execute independently. The threaded programming model provides developers with a useful abstraction of concurrent execution. However, perhaps the most interesting application of the technology is when it is applied to a single process to enable parallel execution on a multiprocessor system.Many programme...

  Simple explanation about process and thread

Process and thread are two basic concepts of operating system, but they are a bit abstract which cannot be  mastered easily. There is an analogy which explains these concepts very well. 1. The kernel of the computer is CPU, it handles all the computing tasks, it's like a factory and will run all the time. 2. Assume there is power limitation for the factory, it can only supply to one unit once,i.e, when one unit is working, other units must stop and wait. The meaning behind this is that eac...

  What Separates Good Designers from Great Ones

Most of the design books you read, including my own, are about how to be a good, competent designer. They are about how to make strong, reasoned design decisions and about design methods and tools. But what they won’t—can’t—teach you is how to become a great designer. The only way to be a great designer is to produce great products. Everything else is…well, everything else. I’m convinced that the people who are great designers, while assure...

  eLearning Can Improve How Educators Approach Learning

eLearning has varied benefits for learners, as has been amply documented across numerous articles on the web. It allows learners to gain access to quality education from the comforts of their homes, according to their convenience. It allows them to focus on their other interests and education at the same time.  When it comes to educators, there’s a dearth of documentation of the positive impacts of eLearning on their work. eLearning has revolutionized the entire learning process, and ...

  Programmer professionalism

Programmer is a lifetime occupation. But first, as a programmer you need to love programming, rather than just an occupation to achieve other goals in life.Now if you plan to spend decades of life on programming, then you should continue to think about what is more efficient. In other words, how are you different from who you were a decade ago and how will you be better than who you are now a decade later?In my opinion, a programmer, regardless of his work, should improve himself in three aspect...
