Overview

  1. Our main goal is to use django to create a project.
  2. Since, django is a python framework, we need to install python to run it.
  3. However, there are 2 major versions of python available - python 2 and python 3.
  4. We're going to use python 3 since it's the latest version available and is way better than python 2.
  5. Pip is the package manager for python, we use pip to install python programs so we don't have to download, configure and install it ourselves.
  6. Managing python versions (2 and 3) is a bit tedious, so we're going to use virtualenv.
  7. Virtualenv will help us create isolated environment for our django project so we can set which python version we're going to use and not worry about anything at all. There are many other benefits of using it which you'll see later.

Verse 1

From time to time, I wonder how, how it all began, how it all prevailed

I think about you and your smile, I have embedded in my mind

From the night we first met each other, to the day we’re in today

Nights go and days come, I can't wait to live with you

Confusion about analogy's of purity in Haskell
View purity-haskell-freenode
[18:27] <trumanshow19> Would someone mind help iron out the
inconsistencies in my head with respect to purity in
Haskell. Statement 1: Haskell is a purely functional lanugage, S2:
Haskell is not impure, but... S3: f :: a -> a is a "pure" function as
opposed to a -> IO a.
[18:27] <trumanshow19> If a -> is pure, to distinguish a -> IO a, then
how do I describe the latter, is there is no impurity in Haskell ?
[18:28] <trumanshow19> The only opposite of pure I know is impure.

Java References and Passing Arguments

Introduction

Java supports references, but it doesn't allow pass by references. Here, we're going to play with Java to understand the concepts better.

References

Let's think of a simple object, such as a string:

String name = "Paul Stanley";

TIV error with JPEG image
View tiv_error.md

TIV failed to work for me when I tried to use it to view a JPEG image. Giving me this error when I tried to view a JPEG image:

[CImg] *** CImgIOException *** [instance(0,0,0,0,(nil),non-shared)] CImg<unsigned char>::load(): Failed to recognize format of file 'raw_images/9.jpg'.

Here are the details of that file:
