Parallel Computing with a GPU

by

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.

Internet Cryptography Demystified

About cryptography

While going through a set of configurations to connect on a remote machine I was asked to upload my public key and I realized that I didn’t really know what that was for. If you are asking yourself the same question, or need to convince your mom she can safely use her credit card online, here is brief summary of what’s going on behind the curtains.

Expanding our Design Toolbox with Lean UX

by

Recently Grio’s design team has adopted Lean UX that enabled us to expand our design toolbox in the following ways:

  • Conduct in-depth Discovery and Research to define the products
  • Inject a user-centric design focus
  • Incorporate “deep collaboration” internally, as well as with our clients

Building Better Products with UserTesting

by

Grio Design is showing some blog love this week! We’ve been busy making clients happy by solving wicked design problems and producing beautiful interfaces, but I wanted to take some time to talk about user experience design (UX), usability, and how UserTesting can help everyone reap the benefits of usability testing.

Meteor

by

For the past year, I’ve been working mainly with AngularJS and before that Ruby on Rails. I’ve never heard of Meteor until a few weeks ago. I am intrigued by the idea of tightly connecting the client and server together in a synergistic manner that allows for fast responsiveness, which is what Meteor is all about. I decided to go through Meteor’s tutorial online and get a feel for why the framework differentiates itself from other current technologies. From a very high level perspective, Meteor is a very good solution for quickly building an application from the ground up and provides some cool features out of the box.

Git Merge Workflow on Github

How to Merge Code

Below is a guide that I wrote for a recent project explaining a git merge workflow on Github. Often times, when you develop a new feature, you will create a new branch off of master called a feature branch. On the feature branch, you might have many commits to save your progress, or when you complete certain milestones of that feature. Once you finish the feature, you will want to merge this branch back to the master branch. However, you might not want all your commits to show up in the git log history because they were only for development purposes. We can overcome this issue by using a feature of git called interactive rebasing which allows you to squash certain commits and customize the commits that will eventually show up once the branch is merged to master. I have described the steps to achieve this outcome below.

Purpose

This guide explains how to develop and commit your code using git and GitHub. A developer should create a feature branch when developing new code. In the feature branch, a developer may commit multiple times during development including making changes based on comments from a code review. When development is completed and the feature branch is ready to be merged in to the master branch, the developer should squash the commits in to one, so that the git log history is kept clean.

Coding Styles and Standards

by

One of the main reasons for having coding standards is to keep your code readable by everyone. By enforcing standards and formatting, the code base becomes consistent, and anyone can easily understand the structure of the code because he will be more familiar with what to expect. It is also very useful when a new developer joins the team because once he is familiar with the patterns, he will be able to easily read the existing code, which results in a more pleasant experience.

Writing Awesome CLI Tools in Ruby: Part I

by

Introduction

I am always writing small tools to help me out on a daily basis. Sometimes shell scripts, but
other times I want something a bit more complex. When I need more than a simple shell script, I like to leverage ruby for its vast library of gems which can greatly accelerate and simplify the task of building these helpful tools.

This post will give an introduction to writing your own CLI tools in ruby and packaging them
as a gem.

Hiding Android’s System Bar

by

For years developers (and consequently consumers), have had to accept the fact that the Tablets (and some phones) would always have the System/Navigation Bar visible on their screens. A 10.1 inch advertised screens, offered in fact a 9.8 inch usable screen.

Finally Google’s latest Android OS, KitKat, introduces a decent user-friendly tool that gives us ownership of that last bit of screen.

Whobert Needs Your Help

Here's Whobert!

Who Am I?It seems Whobert has a bit of a problem; he can’t remember a thing.

Okay, so he’s a wizard.  That much is clear: hat, beard, robe… we’ve got that part.  But there are so many questions!  Where did he come from?  How does he know magic?  Why is there an owl on his head?  Nobody knows. And Whobert can’t remember!
