Big Data and What Data Scientist Do ?

Hi, i am on my personal project (again), about Big Data Learning.
Until when i am googling, i have founded this presentation:

It could be open my mind, how to create some approach to manipulation data in order to more data-product-able. As an overview, big data processing by data scientist with steps consist of:

  • Explore Data
  • Represent Data
  • Discover Data
  • Learn From Data
  • Data Product
  • Deliver Insight
  • Visualize Insight

For keeping my consistent in personal project, i write it in this post.

Thank you

Data Analysis & Visualization with Python (Preparation Phase)

Hi, i am in my personal project, that is Data Analysis & Visualization with Python.
These below information was my notes for project’s preparation.

Source: “Python for Data Analysis”, by Wes McKinney, O’Reilly Publisher

Python libraries which were needed.
> Pandas
This library could be installed with MacOS Terminal by command “pip install pandas”.
Library which combines about
a) high performance array computing feature from NumPy Library
b) dan, flexible data manipulation capabilities from Spreadsheet dan relational database

> NumPy (Numerical Python)
This library could be installed with MacOS Terminal by command “pip install numpy”.
Library as the source of figure Scientific Computing in Python, the package contents consist of: – a “multidimensional object array” which was called “ndarray”
– source of mathematic functions and many operans for array management
– tools for read-write array based data sets

> (matplotlib)
This library could be installed with MacOS Terminal by command “pip install matplotlib”
Library which usefull for producing plots and 2D data visualizations.

> IPython
This library could be installed with MacOS Terminal by command “pip install ipython”
Standard library for filter scientific in Python, the usage of IPython could be combined with matplotlib.

Thank you

Story Telling with Data dot com

Wow, i just added my browser bookmark with Story Telling with Data. And this post title as same as the book, which the writer was Cole Nussbaumer Knaflic.

By wiley.com, there is book overview as below:
The book (Storytelling with Data) teaches you the fundamentals of data visualization and how to communicate effectively with data. You’ll discover the power of storytelling and the way to make data a pivotal point in the story. The lessons in this illuminative text are grounded in theory, but made accessible through numerous real-world examples—ready for immediate application to your next graph or presentation. This description is illustrated on blog-section of storytellingwithdata.com

The sample is how to use bullet graph to make data-owner easier to explain the others. Storytelling is not an inherent skill, especially when it comes to data visualization, and the tools at our disposal don’t make it any easier. The book demonstrates how to go beyond conventional tools to reach the root of your data. And also how to use your data to create an engaging, informative, compelling story.

By wiley.com, specifically in this book, you’ll learn how to:

  • Understand the importance of context and audience
  • Determine the appropriate type of graph for your situation
  • Recognize and eliminate the clutter clouding your information
  • Direct your audience’s attention to the most important parts of your data
  • Think like a designer and utilize concepts of design in data visualization
  • Leverage the power of storytelling to help your message resonate with your audience

This book will help the reader turn data into high impact visual stories that stick with audience target. Rid your world of ineffective graphs, one exploding 3D pie chart at a time (wiley.com).

Code Again, for Small Business 3d Printing

Since Sept 2016, my friends and I had launched http://www.bikin3d.com, the small business at Karawaci which had product about 3d printing services.

As Co-founder and CIO, my job desc were decide the supporting system and technology that make the small business more effective, include at area marketing, pricing, sales and many more.

There was an initiative from the Founder (Lead of Operational) “How about the website visitors can upload their 3d model into our website ?”

This challenge, make me so curious. In my mind there was statement “I have to prove this!”. Finally, this curiosity made me To Do Web-Code Again. I had involved in many activities for feature upgrade on http://www.bikin3d.com. I had to built some scripts, in order to 3d model should be uploaded into website, beside email into sales@bikin3d.com.

Until, I have found some references to do this. My deadline for this update is 4th week on June 2017. Hopefully, based on these references it could be done on-time ^_^.
