If you are new to machine learning?

As per Kaggle (The Home of Data Science) if you are new to machine learning it is recommendation to do these interactive Titanic Dataset tutorials:
  • From R people - Provided by DataCamp this tutorial.
  • For Python people – Provided by Dataquest this tutorial.
More info related to the Titanic Dataset see the this url

I am doing the R tutorial and it is brilliant, easily to follow and fully interactive - You do not need R/R-Studio installed on your machine - you just need browser. I must admit, I used the R/R-Studio for an additional validation. However this is not needed, you could do that all via interactive console.

The fastest way to learn Swift







For some time I was out of Swift programming and Xcode IDE. And to refresh my knowledge, I was google–ing for a nice videos to speed up my recovery process and I was lucky to find the “Code With Chris” channel and play list “How To Make an App with Swift, Xcode 6 and iOS 8” the URL ... URL https://www.youtube.com/playlist?list=PLMRqhzcHGw1Z0S7hpE30r2lwnovSHMntI      

Almost, I finished the play list and I am very impressed how Chris methodically introduces Xcode and Swift (object programming) via his channel.  

I am highly recommending this play list for anybody interested to learn Swift and/or Xcode 6.

PS. I said that I was lucky, to bump on the “Code With Chris” channel, I don’t think that any more – 15 videos were viewed 579,208 times – that is recommendation by it self. 

Swift - intuitive new programming language created by Apple for building iOS and Mac apps.

Xcode IDE - Integrated development environment (IDE) containing a suite of software development tools developed by Apple for developing software for OS X and iOS.
