Updated on: 2015-07-08
Posted on: 2015-07-08
A great part of the production Web sites are hosted on Linux based systems. However the vast majority of the Web developers run Windows or Mac OS X on their development machines.
Vagrant is an application that creates and configures virtual development environments. It can be used as a simpler wrapper solution around virtualization software such as VirtualBox, VMware, KVM and Linux Containers (LXC), and around configuration management software such as Ansible, Chef, Salt and Puppet.
Read this article learn how to use Vagrant to easily setup your Web applications development environment in a way that it is as close as possible to the Linux based environment that you have on your production server.

Updated on: 2015-06-24
Posted on: 2015-06-24
With the speed at which technology is changing and advancing, it is disappointing that as developers and designers we still can’t get the big picture of our site’s user experience.
On the one hand, there are many great Web analytics tools out there today that measure user behavior. There are also many popular customer feedback tools that help to understand the voice of the customer. But fusing these two disparate pieces of information into one concise tool is a largely untapped area in our industry.
As a developer, more tools means more headaches and more overhead. As a designer, you need several key data points to create better sites and solutions around your users, but this data can be hard to find and take action on when you need to use a handful of independent tools and draw insights from them yourself.
Read this article to learn about a powerful new approach to understanding the whole user experience and how to improve it with Hotjar, an all-in-one analytics and feedback tool.
