Is R becoming Irrelevant compared to Python in Data Science

Karma is a bitch. The language R which once claimed to bury SAS language in data science is increasingly losing share of market and share of mind in data science.

TensorFlow. Deep Learning. Advanced Text mining. Computer Vision. Cloud data science pipelines.

All embrace Python faster than R.

Is R still Relevant

Hack for Change #hackforchange

As part of National Day of Hacking, I took part in the hackathon in New York. Here were some insights

A few teams had come prepared reading the challenge questions. These teams had an advantage on time

Creating something in time was a big challenge ( how do you make a product in a single day)

Hackathon consists of 1) organizer giving challenge questions 2) people coming to venue 3) making teams 4) working together as team 5) presenting results (usually one person per team)

The idea is the most important in how relevant and closely aligned to the questions in hackthon you were. Creativity rules

The next important thing was making a balanced team in which everyone gels well, and have skill sets that are complementary ( one front end, one back end, one data scientist in Python, one person who is good at presentation etc)

The next important thing was not getting intimidated by other teams and working on your team idea till last moment

The presentation should be given to a person who is best at expressing 1) what you did 2) how the solution is innovative 3) how it is relevant and useful to challenge

Lastly have fun hacking. People who have fun hacking generally tend to be better hackers.

Install wxPython in Ubuntu

wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module (native code) that wraps the popular wxWidgets cross platform GUI library, which is written in C++.

At a terminal, enter “lsb_release -a” to print what version of Ubuntu you have.

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.5 LTS
Release: 12.04
Codename: precise

$ lsb_release -sc
precise

Add key
sudo apt-key adv --fetch-keys http://repos.codelite.org/CodeLite.asc

  • Then add the source:

sudo gedit /etc/apt/sources.list

deb http://repos.codelite.org/wx3.0.2/ubuntu/   precise  universe 

sudo apt-get update

  • Now install wxPython

sudo apt-get install python-wxgtk2.8 python-wxtools wx2.8-i18n

 

sudo apt-get install python-wxgtk2.8 python-wxtools wx2.8-i18n libwxgtk2.8-dev libgtk2.0-dev

 

Installing Ipython Notebook on Ubuntu 12

I ran into a series of errors and finally managed to make Ipython run on my Ubuntu 12. Notice I am adding some extra stuff in terms of mathjax and pandoc but that is just for a smoother install. Note the trouble point was the package pyzmq but it was troubleshooted by both the –upgrade option as well as the installing of python-dev

sudo apt-get install python-pip
sudo apt-get install python-dev

sudo pip install --upgrade ipython[all]
sudo pip install invoke
sudo pip install jinja2
sudo pip install --upgrade pyzmq

sudo python -m IPython.external.mathjax
sudo apt-get install pandoc
sudo pip install tornado jsonschema
