Fractals: Why am I Repeating Myself?
You may have seen them on college dorm room walls or on your plate of cauliflower… you may know them when you see them, but what are fractals, really?

SQL & NOSQL: A Brief History
The Relational Model & SQL
The relational model was proposed in a paper published in 1970 by Edgar Codd, a computer scientist working at IBM. In previous years, some storage systems had already emerged, but the relational model was first proposed with a strong theoretical basis.
Content Delivery in P2P networks
Scalability is a hot topic, especially in Content Delivery Networks (CDN) where scalability, robustness and availability are crucial. A CDN is a system that has the aim to deliver Web content, such as videos, images, and any other type, to end users. Content providers such as media companies need to deliver their content with high availability and high performance, and CDNs offer them the infrastructure to do it. There are different approaches, each one with its advantages and flaws.
An Introduction to Elliptic Curve Cryptography: With Math!
Modern cryptography is a very murky subject for many people, so today I will try to explain to you one of the more complex subjects, Elliptic Curves. Many of you may have heard their name before, but likely don’t know much about them beyond that. To begin, I will describe what an elliptic curve is.
Intro to Software Methodologies
Software Engineering is about more than just writing code. It is a complex process that has a lot of moving parts. Requirements gathering, planning, testing, deployment and source control management are just a few of the pieces to the software engineering puzzle. So how do we manage all this complexity? Software methodologies come to the rescue.
Chrome Extension Basics
I use Chrome extensions all the time and decided it was time to figure out how to make my own. I found it to be incredibly easy and I’d like to share with you some of the basics, as well as an example of an extension I made. Let’s get started!
Drinking The Koolixir – Part 2
To get a better handle on Erlang’s behavior, I decided to install a popular set of tools for debugging and performance profiling: EPER. I think it stands for “Erlang PERformance tools”, but it could also mean “Everything Proves Erlang Rules” or “Egrets Prefer to Eat Robots” or really anything for that matter. One thing is for certain, however: getting these tools built and running on Mac OS X was fraught with danger and build errors.

The User Experience Team of One: A Research and Design Survival Guide
I’ve recently made it one of my goals to learn more about UX and design. To that end, I read a book that was highly recommended by our Grio designers, The User Experience Team of One: A Research and Design Survival Guide, by Lean Buley. The book is written for people who are or want to be UX professionals, with a focus on those who either the only person in their company working on UX or who are in some way UX evangelists in their organizations. Although the intended audience of the book is UX professionals, there were also number of tips and ideas that a company like Grio can find useful. On many projects, especially when budgets and time are tight, Grio takes on the role of UX evangelist for our clients.
Parallel Computing with a GPU
Graphic Processor Units are becoming more and more important in recent years and are spreading into many different fields, some of which include: computational finance, defense and intelligence, machine learning, fluid dynamics, structural mechanics, electronic biology, physics, chemistry, numerical analysis and security. There are many reasons why a person should learn how to write code for a GPU. For example, GPU’s have been used to successfully decrypt passwords (add reference) in record time, a 25-GPU cluster is able to crack any standard Windows password (95^8 combinations) in less than 6 hours. Other applications of the GPU include data mining for Bitcoin and also applying machine learning for sentimental analysis on tweets.
