Domain Specific Languages (or Libraries because embedded DSLs are just that) are already quite popular.

Modern languages have many useful language features that are conducive to create DSLs with more ease than ever before. Kotlin from JetBrains is a beautifully blended pragmatic programming language that packages many features from many programming languages. Kotlin also have infix operation which makes code written in a DSL made with Kotlin very easy to read (and therefore less error-prone).

In this demonstration, I shall show couple DSLs made from Kotlin

and will dissect the code LIVE to show audience how several language features in Kotlin (which sometimes requires playing with higher order functions) to develop these languages.

*A Unit Testing DSL (a DSL to simplify unit testing of Kotlin, Java Code) that our grand/m/pa can use.

-- All unit test frameworks serve the purpose but elegance is a different matter. A code that works, and a code that is elegant and works is art. In this example, audience will see how they can use several language features that Kotlin has to offer can be put together to create an elegant and expandable unit testing DSL.

* A DSL for Web Scraping and Transformation.

- - A special case of ETL, where Extraction happens from raw HTML, Transformation happens in memory using the DSL designed. and the Load happens by loading this data to a different schema/db/form/representation.

Machine learning is more popular than ever because there are several dataset available and we can use several tools at our disposal to learn an insight from this data.

In this session I shall show how F# can be used for several machine learning tasks and I will be using industry standard APIs

During this session participants will be solving several machine learning challenges from Kaggle like handwritten digit recognizer (https://www.kaggle.com/c/digit-recognizer)

During this session participants will write code in F# to solve real challenges like this one

https://gist.github.com/sudipto80/72e6e56d07110baf4d4d

and they will get to understand the process of machine learning system design pipeline.

This is a demo session about Squirrel framework. Squirrel in an open source data analytics framework for .NET

https://github.com/sudipto80/Squirrel

Here are some of the case studies that will be demoed. These questions will be posed and then the solution will be provided using Squirrel

Hope that audience will be able to appreciate the elegance and simplicity of the solution that Squirrel provides.

1. Do women pay more tip than men  ?

2. How many accidents happen becasue of bird strikes ?

3. Which country is famous for which sport in Olympics ?

Please visit Squirrel github page https://github.com/sudipto80/Squirrel to see some of these examples

At the end of this session, data from Squirrel will be taken and then some infographics will be generated that can make life lot simpler for data journalists.

In other words, it will be the attempt to make each developer realize that they can be a data journalist.

We shall have few T-Shirts to give away with the nice Squirrel logo and our motto. But I hope you shall have other motivation to come to this session :)

LINQ draws on principles of functional programming and represents a paradigm shift for developers used to an imperative/object oriented programming style. Thinking in LINQ explains the benefits of functional programming built into LINQ, allowing developers to use these techniques write more efficient and concise data-intensive applications.

While other books on the subject merely scratch the surface in terms of problem solving using LINQ, Thinking in LINQ (http://www.apress.com/9781430268451)  shows readers how use functional programming techniques to solve common every-day problems as well as more complex problems using LINQ’s features.

LINQ lets you write code that resembles natural language and is easier to debug compared to traditional loops and branching statements. The purpose of a well written LINQ Query will be immediately evident unlike the looping construct so commonly used in traditional programming. LINQ operators can be used in unison to orchestrate a solution for complex real world problems.

What viewers will learn

• Text Processing using LINQ
• Refactoring using LINQ
• Monitoring code health using LINQ
• Creating DSL using LINQ
