Parallel universe: Perceptions from an immigrant

On a metro train travelling to SHARAF DG station, . It has been an intense “yesterday” seeing death, life and the decisions you make when there is a soul trying to escape this world to travel onto another.

In a different country travelling from a different country always trying to relate the whole world and its existence to the people you love. People you love being the ones you meet, the people who got you here, the ones you are born with, the ones you want to die with. This whole existence is an art and is always interpreted upon different phases that we go through as a good and bad. The balance of thoughts or the non neutrality of the mind makes every art an interpretation to experience in life.

All about Google WiFi Positioning System

WiFi Positioning system is a new way to get precise localisation. It is used in conjunction with GPS to achieve better accuracy. Read through to know how there is a slight privacy intrusion and how you can take care of your privacy issues. I am also sharing some interesting things about this WiFi Positioning System (WPS) that Google offers through its developer API.

It is interesting that Google asks for you to sign up for logging the access point (AP) information in your android phone. Well if you knew when and where it is asked, you will surely hit NO!

They collect your AP information mostly without clear notice and then you have to pay to use the API to access this information. Atleast this is what Google does.

Well some digging says it is just done periodically. My conclusions of how AP information tagged with location is logged are as follows

  • It is somewhere connected to location reporting from Google Location Services.
  • It could be just the localisation data that is sent to Google to while you are using your apps that require location.

So Google actually logs all the Access Point (AP) a device connects to and with the help of GPS it is geolocated and the info is tagged and sent to Google servers!

How to opt out of this WPS?

My endeavour towards creating cheap backup space

I started good with a 512GB HDD and a Dell Studio with a 512GB HDD in 2009.
I was never out of space until 2013 when I bought my new MacBook Air with 256GD HDD. I would describe it as a glorious decision but totally not happy with the 46GB free space!
Since then I m trying to find out a best way to create more storage space and I am going away from the idea of using a physical device since I like to go mobile and light. I want it to be accessible all the time i.e. even without carrying my storage device. Continue reading “My endeavour towards creating cheap backup space”

Did I know: A water fountain could produce 1,33,303 ?

I always think how much this setup could pump out?

This is a fountain at Technical University of Dortmund.

Too much in to thinking and I was spoiled by my Statistics for Reaseachers and Engineers (SRE) course!

It made me think, why not compute.

What I found is about potatoes that can be grown out that fountain running through the summer was interesting.

This was more of an academic endeavour for me.

I made a test by conducting a trail for measuring the water flow through it!

Now why not use R project for the purpose of computing?

I know its a lame for using such a powerful tool for a simple math but its not bad for getting around R!

some of the assumptions made:

Diameter of the pipe = 1 cm
flow rate is constant for 6 months

if someone is able to measure it > comment in the post!

Formula used:

http://www.1728.org/flowrate.gif
formula used from www.1728.org will be implemented in R Code

Formula in R

pipeDiameter = sqrt (4 * flow / pi * velocity)
velocity = (4*flow) / (pi * pipeDiameter^2)
flow = 1/4*pi*(pipeDiameter)^2*velocity

A bottle was filled in 21 seconds. Winny was the time keeper. It was a 1 litre bottle. So scientifically saying it took 21 seconds for 1000 millilitres. (Please comment if you have more accurate results to take a list of values from different trails to make the calculations more robust)

> flow = 1000 /21
> flow
[1] 0.04761905 # litres / second

The above data was to get the facts straight and may be I would use it later. Since flow rate is assumed to be constant for 6 months which is the period the fountain is in service. I want the time to be six months since it is only on during the summer and during the winter it is going to be frozen!

Let me try to find out how much water is being pumped out during the service period in the next page.

Setting up your first psychoPy application in Eclipse

http://www.psychopy.org

I believe you have already ready the previous post about setting up the environment. if not do it here! <PSYCHOPY APP DEVELOPMENT IN PYTHON USING ECLIPSE AND PYDEV>

So, now you are for sure ready with the environment and already created your first application on python. But psychoPy? yes, its not a big deal, you are 80% complete from creating an application in psychoPy already.

These following steps hit the rest 20%.

Set up the interpreter to be psychoPy. This enables you to use psychoPY API. Continue reading “Setting up your first psychoPy application in Eclipse”

PsychoPy app development in Python using Eclipse and pyDev

Install and setup psychoPy and using Eclipse and python for development of applications. I developed an application that used a eye tracker. It was a great idea to use python to interface the eye tracker with the routine which was created using psychoPy.

Creating a new pydev module to start coding
Creating a new pydev module to start coding

In this post, it is only about installing psychoPy, Python, Eclipse, pyDev for Eclipse and starting a new project. Creating your first psychoPy application with its specification will be in the following post.

Hello world!

Welcome to my blog.

I am writing to document my findings and experiences in various projects.

It may not be informational, it may not be commercial but it is for a personal satisfaction!

This took a long time to set up the WordPress website and I had to contact the host to figure out some of the compatibility issues.
