Dancer is a web application framework designed to be as effortless as possible. Dancer only requires a hadful of CPAN modules and is very self contained. It includes standalone development server that can be used for developing and testing applications. It supports the PSGI specifications and can thus be run on any compliant PSGI server, including PLACK, uWSGI or Mongreal2. Since most part of Dancer are abstracted and has a plugin architecture, extending Dancer is fairly strightforward, and a thriving community has sprung up arounf building these extensions. It aims to provide simplest way for writing web applications and offers the flexibility to scale between a very simple lightweight web services consisting of a few lines of code in a single file, all the way up to a more complex web application with session support, templates for views and layouts etc.If you don't want to write CGI scripts by hand and find catalyst too big or cumbersome for your project, Dancer is what you need.

Dancer is a very versatile tool. It allows you to scale between a lightweight web service to a more complex application. Webapps are easy to deploy. Dancer is simple and easy to use. I highly recommend it.

Octave is the best utility software which i have used for starting my machine learning.It is very easy to use and it is also very less demanding on cpu so,we can use it with an uninterrupted experience.It is very good for Algorithm development and it is very easy to do data visualization on GNU Octave.It is also very easy to do vectorization for data science purposes. The CLI version is very light on my computer so it uses very ram and cpu speed.It's is the best software to use use when we enter the field of Data Science and Machine Learning.Everyone must have some experience with GNU Octave.
