Hot Technologies for Data Science

2017-10-14T04:07:00.001-07:00

It is really confusing when you read about the Data Science and its technologies; If found very helpful information from Forbes Magazine and DataCentral Websites. 

Gil Press posted a list of top 10 hot big data technologies in Forbes Magazine. The technologies being featured as hot were:

Predictive analytics
NoSQL databases
Search and knowledge discovery
Stream analytics
In-memory data fabric
Distributed file stores
Data virtualization
Data integration
Data preparation (automation)
Data quality

DataCentral website wrote the article on it and mentioned the hottest technologies as they know are the hot one:

Adapting modern predictive algorithms to a distributed architecture
AI (pattern recognition)
Deep learning (the interection of AI and machine learning)
Data science automation
Leveraging data from sensors (IoT)
Turning unstructured data into structured data, and data standardization
Blending multiple predictive models together
Intensive data and model simulation (Monte-Carlo or Bayesian methods), to study complex systems such as weather, using HPC (high performance computing)

What do you think are the hottest technologies now? Do you agree with Gill & Vincent Granville?

How to find your iPhone , iPad UDID ?

2017-07-28T22:41:00.004-07:00

Finding your iPhone, iPod touch or iPad’s unique ID (UDID)

Every iPhone, iPod touch and iPad has a unique identifier number associated with it, known as a UDID (Unique Device ID). Your UDID is a 40-digit sequence of letters and numbers that looks like this: 0e83ff56a12a9cf0c7290cbb08ab6752181fb54b. It’s common for developers to ask for your UDID as they require it to give you beta copies of iOS apps.

Finding your UDID using iTunes

Open iTunes (the Mac or PC app, not iTunes on your iPhone).
Plug in your iPhone, iPod touch or iPad.
Click its name under the devices list.
Ensure you’re on the Summary tab.
Click on the text that says Serial Number. It should change to say Identifier (UDID).
Select Copy from the Edit menu.
Your UDID is now in the clipboard, so you can paste it into an email or message.

Software Architecture - Three Layers Should Be Enough for Everybody

2016-09-20T04:27:00.001-07:00

Three Layers Should Be Enough for Everybody

If think about the responsibilities of a web application, we notice that a web application has the following “concerns”:

It needs to process the user’s input and return the correct response back to the user.
It needs an exception handling mechanism that provides reasonable error messages to the user.
It needs a transaction management strategy.
It needs to handle both authentication and authorization.
It needs to implement the business logic of the application.
It needs to communicate with the used data storage and other external resources.

We can full fill all these concerns by using “only” three layers. These layers are:

The web layer is the uppermost layer of a web application. It is responsible of processing user’s input and returning the correct response back to the user. The web layer must also handle the exceptions thrown by the other layers. Because the web layer is the entry point of our application, it must take care of authentication and act as a first line of defense against unauthorized users.
The service layer resides below the web layer. It acts as a transaction boundary and contains both application and infrastructure services. The application services provides the public API of the service layer. They also act as a transaction boundary and are responsible of authorization. Theinfrastructure services contain the “plumbing code” that communicates with external resources such as file systems, databases, or email servers. Often these methods are used by more than a one application service.
The repository layer is the lowest layer of a web application. It is responsible of communicating with the used data storage.

How to install Django on Mac OS X

2015-12-16T23:50:00.002-08:00

Django is a web application framework for Python for developing web applications. Django is written in Python programming language and is open source. Based on DRY(don’t repeat yourself),reusability principles, complex web application development becomes easy in Django.

It is generally said that “Django is for perfectionists with deadline.”

Unlike Windows, development environment is like Linux in Mac OS X, so if you have been using Linux, you won’t feel any difference. Follow these steps to steup Django 1.7 on Mac OS X.

Step 1: Press “F4” and open “Terminal”

Step 2: Lets first install pip (it is used to install python packages). On the terminal type this command and when prompted for password, enter your Mac OS X (computer ) password.

sudo easy_install pip

Step 3: Now to install Django, type the command given below and then password of your mac is prompted.

sudo pip install Django

Step 4: To check which version of Django is installed in your Mac, enter this command

django-admin.py --version

Step 5: Creating django project is easy, just type this command

django-admin.py startproject projectname

this command will create a django project and to run this project, first navigate to project folder and then start server.

cd projectname

python manage.py runserver

No you can go to http://127.0.0.1:8000 to check if it works.
You’ll see something like this(django’s default page).
