As Java Programmer, "Where has C# been when I was programming In Java "?

As a certified Java programmer I have been living in the Object world maintaining my states, favoring composition over inheritance and using design patterns until multicore CPU's came into the market. You maybe asking why did multicore cpus disrupt my object oriented world? Here is why - It's time to get good at functional programming. The main thing in the article is the parallelism of functional programming to take advantage of those multi core cpus. Variables and data in functions will not have the side effects (deadlocks, race conditions) that we see in an object oriented language like java because functions only depends on inputs and not on any global state (translation - they only have local variables which is always thread safe). 
So how does this relate to C# ? Well the designers of the C# language was heavily influenced by Haskell (functional programming language. Erik Meijer worked on LINQ in C#). 
I am liking, favoring and talking about C# because of this (even though Java 8 will have lambda expressions lambda expressions) 

Here are my top three favorites things in C#:

1. Lambda Expressions - (specially used with LINQ)
   lambda expressions are anonymous functions (C# lambda expressions). This makes evaluating collections and enumerations really easy.   
2. Function Types
   a Function is a type (like javascript) you can pass the functions around and create higher order functions.
3. Object Literals
   enough with the get and set methods in Java. (Object literal in C#)

 I hope that Java 8 will not disappoint me.

Side Note:

Functional programming had roots from the 1930's from Alonzo Church's Lambda calculus. Hence the term Lambda Expression.

OAuth 1.0a Request Signing and Verification - HMAC-SHA1 - HMAC-SHA256

Image
This is a security project that I did this Fall semester. I was interested in why the OAuth1.0a specification did not require you to sign a request using RSA-SHA1 or any RSA algorithm. The first issue that I found is where would you store your private keys in a javascript client? - as a javascript encrypted file ? from the browser ?  - that will be a security hole if you allow javascript to get private keys. These are some of the questions that got me asking and which I cannot find answers to for now. OAuth 1.0a Signature Signing and Verification using JavaScript Implementation Background The OAuth specification tries to define an API authentication method that allows consumer websites or applications to access protected API Resources from a Service provider. The advantage that OAuth provides is that the user of the website or application is not required to disclose their credentials to their service provider. Another advantage of using OAuth to authenticate is that it does not

Spark DataFrame - Array[ByteBuffer] - IllegalAurmentException

IllegalArgumentException - ByteBuffer - Spark DataFrame I was processing a several million documents (~ 20 million) in which we need to extract the NLP features using NLP4J, OpenNLP, and WordNet. The combination of the three NL features blows up each record to 11 times its original size. We are using all three because we do not know yet what feature sets will be helpful to us. The original dataset is in parquet files in HDFS (16 partitions). I thought that was convenient just use withColumn and pass a UDF (User Defined Function) on the column where it needs those features. withColumn adds the calculated column back to the DataFrame. So I created the spark job (I am on Spark 1.5.2-cdh5.5.2)for the above, and things started to get nasty. I am blowing up the ByteBuffer array on the in-memory columnar storage. This is the exception that I am getting. There seems to be no reference in my code in this stack trace. java.lang.IllegalArgumentException at java.nio.ByteB

Gensim Doc2Vec on Spark - a quest to get the right Vector

Ever since I joined the R & D group we have been doing a lot of cool things, like trying IBM Watson (see previous blog entry). Now we are doing a lot of Natural language processing.  We wanted to compare the similarity of two documents. There is this excellent project Gensim ( doc2vec ) that easily allow to you to translate large blocks of text to a fixed length feature vector to make comparisons. Here is the link to the  original paper  from some people from Google that explains the approach. In essence, they wanted to find a representation that will overcome the weaknesses of the bag of words model. The doc2vec approach proves to be a reliable approach to comparing similarities of documents because it takes into consideration the semantics and the order of the word in context. So with that, we wanted to use it for a corpus of 26 million documents. Calculating the doc2vec for 26 million documents is not a small task, so we need to process it in Spark. The problem is that there
