Ecommerce in the Django World
By Kirk Harr
December 3, 2014
Mezzanine (http://mezzanine.jupo.org/) is a powerful piece of software written for the Django Framework in Python that functions like a structured content management system similar to Drupal, WordPress, and others. Built on top of this CMS structure is a module which adds features for Ecommerce which is known as Cartridge (http://cartridge.jupo.org/).
Installing Cartridge/Mezzanine
Installing the Mezzanine CMS system from scratch can be accomplished in two methods, either by using the pip python package manager, or you can clone the current source from the git repository from the software maintainers. If you were planning to modify either Mezzanine or Cartridge to customize the setup for your own needs the latter would likely be preferable as you could then easily begin creating custom branches off the original source to track the customization work. However for this example I will show the pip method of installation:
pip install -U cartridgeOnce installed, there is a mezzanine-project command which will allow you to create a new blank Mezzanine environment within a new directory, and in this case we will also send an option to instruct the command to install the Cartridge module …

Easier IE Site Testing With RemoteIE
By Greg Davidson
December 2, 2014
Microsoft recently announced a new service which I’m finding very useful. RemoteIE lets you test your sites with IE (currently version 11) on Windows 10 Technical Preview. The service runs in Azure RemoteApp which is available for several clients including Android, iOS and Windows Phone. What’s great about this is that you do not have to install and maintain your own virtual machine with VirtualBox or VMWare.
To use RemoteIE you’ll need a valid Microsoft account—it’s easy to sign up if you don’t already one. Once you have an account and have downloaded & installed the Azure RemoteApp client of your choice it’s just a matter of starting it up and logging in. Happy Testing!

MySQL to PostgreSQL Migration Tips
By David Christensen
November 26, 2014
I recently was involved in a project to migrate a client’s existing application from MySQL to PostgreSQL, and I wanted to record some of my experiences in doing so in the hopes they would be useful for others.
Note that these issues should not be considered exhaustive, but were taken from my notes of issues encountered and/or things that we had to take into consideration in this migration process.
Convert the schema
The first step is to convert the equivalent schema in your PostgreSQL system, generated from the original MySQL.
We used mysqldump --compatible=postgresql --no-data to get a dump which matched PostgreSQL’s quoting rules. This file still required some manual editing to cleanup some of the issues, such as removing MySQL’s “Engine” specification after a CREATE TABLE statement, but this resulted in a script in which we were able to create a skeleton PostgreSQL database with the correct database objects, names, types, etc.
Some of the considerations here include the database collations/charset. MySQL supports multiple collations/charset per database; in this case we ended up storing everything in UTF-8, which matched the encoding of the PostgreSQL database, so there were no …

Integrate Twilio in Django
By Kulbir Singh
November 24, 2014
Twilio
Twilio is a powerful HTTP API that allows you to build powerful voice and SMS apps. The goal of this blog post is to help make building the SMS applications as simple as possible in django.
There is a already Twilio Python help library available. The open source twilio-python library lets us to write Python code to make HTTP requests to the Twilio API.
Installation
The easiest way to install twilio-python library is using pip. Pip is a package manager for Python.
Simply run following command in terminal.
$ pip install twilioTwilio API Credentails
To Integrate twilio API in django application, we need TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN variables. These variables can be found by logging into your Twilio account dashboard. These variables are used to communicate with the Twilio API.
You’ll need to add them to your settings.py file:
TWILIO_ACCOUNT_SID = 'ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
TWILIO_AUTH_TOKEN = 'YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY'Create a New App
We are going to interact with people using SMS, so I prefer to create an app named communication. I am assuming you’ve already installed Django.
Run following command in terminal.
$ django-admin.py …django python saas api
When Postgres will not start
By Greg Sabino Mullane
November 24, 2014
One of the more frightening things you can run across as a DBA (whether using Postgres or a lesser system) is a crash followed by a complete failure of the database to start back up. Here’s a quick rundown of the steps one could take when this occurs.
The first step is to look at why it is not starting up by examining the logs. Check your normal Postgres logs, but also check the filename passed to the –log argument for pg_ctl, as Postgres may not have even gotten far enough to start normal logging. Most of the time these errors are not serious, are fairly self-explanatory, and can be cured easily—such as running out of disk space. When in doubt, search the web or ask in the #postgresql IRC channel and you will most likely find a solution.
Sometimes the error is more serious, or the solution is not so obvious. Consider this problem someone had in the #postgresql channel a while back:
LOG: database system was interrupted while in recovery at 2014-11-03 12:43:09 PST
HINT: This probably means that some data is corrupted and you will have to use the last backup for recovery.
LOG: database system was not properly shut down; automatic recovery in progress

MongoDB and OpenStack — OSI Days 2014, India
By Selvakumar Arumugam
November 19, 2014
The 11th edition of Open Source India, 2014 was held at Bengaluru, India. The two day conference was filled with three parallel tech talks and workshops which was spread across various Open Source technologies.
In-depth look at Architecting and Building solutions using MongoDB
Aveekshith Bushan & Ranga Sarvabhouman from MongoDB started off the session with a comparison of the hardware cost involved with storage systems in earlier and recent days. In earlier days, the cost of storage hardware was very expensive, so the approach was to filter the data to reduce the size before storing into the database. So we were able to generate results from filtered data and we didn’t have option to process the source data. After the storage became cheap, we can now store the raw data and then we do all our filter/processing and then distribute it.
Earlier,
Filter -> Store -> Distribute
Present,
Store -> Filter -> Distribute
Here we are storing huge amount of data, so we need a processing system to handle and analyse the data in efficient manner. In current world, the data is growing like anything and 3Vs are phenomenal of growing (Big)Data. We need to handle the …
