Why do you prefer Ruby MVC framework over Java Spring MVC framework for backend development?

Hitesh Kumar

Industrial expert and real developer not just a teacher

In "MVC Framework" MVC is the architecture which is common in almost every popular framework... its the framework with a rich library with good documentation and community support which makes the difference... There are many popular Ruby MVC frameworks and you can go through each from this list http://www.fromdev.com/2014/11/best-ruby-web-frameworks.html or no wikipedia https://en.wikipedia.org/wiki/Comparison_of_web_frameworks#Ruby Now the main issue is understanding which one is best? that sometimes depends on answer of certain questions like what application are you making? what kind of audience you have and how large it is? and scalability and customization factors etc. for this, you need to see a comparison including advantages and disadvantages of each... and there are plenty of stuff online to understand this... hope this will helpful

How do you write a program (C++\Python\Java) to install a DHCP server on a remote machine?

Chandra Sanwal

Trainer

The solution would depend on your environment: is the remote system running Windows/Linux? Also, do you really want to write a program to do this? For Windows Server 2012 - on both the remote system and the one on which you are working - the 'Add roles/features' dialog allows you to connect to a remote server and add the DHCP role to it. For a flavor of Linux, say Ubuntu - on the remote system - you can simply open an SSH connection and execute the following command: sudo apt-get install dhcp3-server Presumably, you would also want to then configure it - which can be done by creating a configuration file locally and then pushing it to: /etc/default/dhcp3-server Now let's say you do actually want to write a program to do this: Python Use Paramiko to open an SSH connection and fire the command PowerShell Use the Servermanager module. See Page on microsoft.com for some help. C++/Java This isn't really a low-level computing problem - it's more of a sysadmin and infrastructure management problem. I wouldn't recommend using a language like C++/Java to do this - use a scripting language instead.

How many times faster does C++ outperform Java in scientific calculations?

Chandra Sanwal

Trainer

Usually C/C++ outperform in almost all kinds of processing. All scientific operations and calculations needs high performance. For illustration purpose I tested simple program which prints from 1 to 10 million using C, C++ and JAVA. C++ program takes on an average of 33 sec, JAVA takes on average of 84 sec and C took 26 sec to print on a dual core 2.6 ghz mac. From Benchmark game these are the results for JAVA and C++ (C++ beats in all cases if speed is taken consideration). Java vs C++ g++ (64-bit Ubuntu quad core) But again, you will enjoy the performance of C++ only when it is well written and optimized. If not, you don?t see any difference between it and java. Java is also a beautiful language and it is meant for developing enterprise web applications and it has an inbuilt powerful garbage collection mechanism which C++ lacks and programmers have to take responsibility of destroying the unused objects.
