Geolocation – using PhoneGap features to improve an app's functionality, write once use everywhere
by
Gustavo De La Vega Alvarez | December 2013 | Open Source
This article by Gustavo De La Vega Alvarez, the author of Instant PhoneGap, has discussed how to implement geolocation in our app, we will use the API that PhoneGap provides us as part of a bunch of methods to use through our app. To build this, we need to create a JS file called myplaces.js. Create the file once using a text editor program such as Sublime Text or Notepad. Then we will perform the following steps:

Matt Palmer | December 2013 | Open Source
In this article by Matt Palmer, author of Instant Redis Persistence, we'll step through a number of different scenarios, and how you can go about protecting against each one.
While securing your data isn't strictly a persistence topic, it is an important one to consider when planning your data storage strategy. If your stored data can be accessed improperly, you're in a whole world of pain.
A common complaint about Redis is that it has no means of controlling who has access to the Redis server—if you can connect to the Redis server, you've got the ability to fully access and manipulate the data stored in that server.

Social Engineering Attacks
by
Rahul Singh Patel | December 2013 | Open Source Web Development
This article, written by Rahul Singh Patel, author of the book Kali Linux Social Engineering, introduces social engineering and attacks that currently the industry is facing in the form of e-mail, Advance Persistent Threats (APT).
Social refers to our day-to-day lives, which include both personal and professional aspects; while engineering means a defined way of performing a task by following certain steps to achieving the target. Social engineering is a term that describes a nontechnical intrusion that relies heavily on human interaction and often involves tricking other people to break normal security procedures.

by
Jacobo Rodríguez | December 2013 | Open Source
In this article written by Jacobo Rodríguez, the author of the book GLSL Essentials, we will learn how to set up the shaders from the host application side.
OpenGL 4.3 is a C language API that bases its design in encapsulating objects in opaque handles that represents abstract concepts (from the user's point of view) such as textures, shaders, vertex buffers, and so on. In order to render something using OpenGL, we have to create those objects, associate our data to them, and issue the required OpenGL commands to set them as active, and in the last term, launch the draw call.
Let's define an important computer graphics concept: a rendering batch. A rendering batch is the geometry set that will be rendered along with the textures, OpenGL's states and shaders. Once we have all that data ready, we can issue the drawing command to the GPU, and hopefully (if we did everything correctly) watch the rendering in our screen.
The order of the creation of the different OpenGL objects is not relevant. You can first create the vertex buffer or the shaders, or first the textures and then the shaders. I will use the following order just for teaching purposes:
- Vertex array objects
- Textures
- Shaders
Then, I will put all together and render the batch.
