Greetings,

Have you heard of high-energy visible light (HEV)? HEV is the light all our electronic devices give off and it's bad for your eyes. Besides impacting our behavioral and biological processes, it can cause damage to sensitive cell tissue in our eyes. If you sit in front of a screen for most of your workday and continue the same at home, there are good tips at the bottom of this article to protect your vision. One day there will be technology to replace or repair our eyes but for now, let's take care of them.

All the best to you,

Beryl Morimoto

Program Manager

Mario Mediati is the Technical Operations Manager at PCATT and is a certified instructor for VMware, Cisco, and Red Hat. His knowledge of networking, Linux, computer hardware, VMware, and just being a smart guy make him a valuable asset to PCATT. He manages the virtual environment utilized for training as well as production. When there is a technical problem to solve or solution that is needed, Mario is often involved either directly or in guiding, consulting or mentoring others. We sometimes fondly call him "Super Mario" because he really is super.

     With the release of Ubuntu Trusty Tahr v14.04, Mario experimented by installing it as a virtual machine on his desktop and laptop. He shares the installation steps with you and welcomes your comments and input. We're always experimenting at PCATT, trying out new things so we can expand our experiences and share this knowledge with you.

At PCATT, we love to learn new things. We hope you share our love for learning. Here are the PCATT courses for the month of May. There are just a few things to note:

• CCNA 2: Routing and Switching Essentials

The start date has changed to May 13. You no longer need to take CCNA 1 before CCNA 2 if you have applicable experience.

• Introduction to Ethical Hacking

This new course starting May 29 is taught by Dallas Shiroma, an excellent instructor. Seating is limited because of the hands-on labs so register early.
