In this post, we will go through setting up MongoDB 2.6 together with Django 1.6. By default, Django doesn’t contain support for MongoDB. It isn’t difficult, however, to introduce support for the NoSQL database following the steps in this tutorial.
I recently started using MongoDB and I was struggling setting up the equivalent of a root user and other users in traditional SQL databases. MongoDB comes with authentication turned off out of the box, so in order to use the password challenge authentication, we have to create the root user followed by enabling the authentication. In this tutorial, we will cover that as well as installing MongoDB on Ubuntu.
There are several use cases involving connecting an RC receiver to an Arduino board. One such use case is testing whether or not your receiver actually works. In this tutorial, I will cover how to do the test.
Recently, I needed the C++ Boost library to perform some object serialization. Installing and compiling Boost on my Windows 7 machine using MinGW was a task I spent quite a few hours on before I succeeded to follow the right steps. So I decided to share the process with others who might have similar difficulties.
Since Arduino Uno and Mega DXF drawings are hard to find (I didn’t find any for the Mega board), I created my own and I am sharing them here with everybody. These are saved in the AutoCAD 2007 DXF format. Enjoy!
Recently, I got the Parrot ARDrone 2.0. Enjoying taking control of electronics and software, I wanted to write my own code that will stream the video from the quadcopter to my computer and give me the ability to process the individual video frames with OpenCV. There are lots of examples how to do this for ARDrone 1.x, but virtually nothing for ARDrone 2.0, which completely changed the way it’s streaming the video. After many hours of research and putting different pieces of code together, I got it to work on ARDrone 2.0. In this post, I will show you how to do it.
I recently started using Git and it took me some time to find out how to just get the basics going – create a local repository and push it to a remote repository on my server. In this tutorial, we’ll cover how to do that real quick.
You have a Linux server accessible via SSH, but you need to gain access to the GUI of applications like Gimp, Firefox, etc.? In this tutorial, I will show you how to do this using Cygwin on Windows in a few steps:
