An introduction to Big Data – RackSpace’s CloudU MOOC

CloudU

Several years ago we introduced you to CloudU. A perfect introduction to how the ‘cloud’ works.  CloudU by RackSpace now has a MOOC (Mass Open Online Course) that introduces you to Big Data.

According to Wikipedia, Big Data is a term used to describe a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. Thats a great definition but its only one. This topic is too big to base this learning series on one definition so we asked the brightest minds in academia and the cloud industry the same question, “What is Big Data”? We are confident you will enjoy their insights and take away a broader perspective on big data.       Sign up, it’s free (Link)

“After contacting Rackspace so that my students could benefit from the cloud university curriculum as a supplement.   I was met with open arms and personally talked with Greg Alfaro, Michael Ferranti and Ben Kepes either by phone or email.   Here’s a quote from Ben. - “CloudU is an excellent resource for anyone wanting to learn about Cloud Computing. As an instructor of information technology, the certificate provides a great learning tool for the planning, deployment and logistics behind cloud computing.”    ~ Ben Kepes

MySQL Wworkbench – manage your MySQL installation

If you are a beginner or an expert, MySQL Workbench is a must have if you have installed MySQL.  The community edition allows you to Start/Stop your MySQL instance, write queries, monitor performance and has dozens of other features.

With MySQL, the my.conf file normally found in Linux installs is the my.ini file.  This configuration file can be found under the ProgramData folder (you have to show hidden files in Windows Explorer to see it).   This file can be configured using MySQL Workbench.   If you get an error connecting to it, go to the server instance and navigate to the my.ini file.   This is a common error when reading the configuration file.

Network Access Protection

Windows 2008 Server has Network Access Protection which is also known as NAP or NPS. This tool serves an administrative purpose to help organizations compare the security level in a computer on the network to the Server 2008′s policies. This comparison helps to determine if the computer is safe enough to join and use the Server. This is another way to help find if the computer’s ‘health’ is adequate as far as policy and the NAP can also analyze both the anti-virus program and if the firewall is installed. In an upcoming series, Windows 2008 Server will be reviewed.

Information on NAP from TechNet

Wireless security risks and defenses – Help Net Security

An interview with Kent Lawson, CEO of Private WiFi – Help Net Security

Do you think it is time to think of an alternative to WPA encryption?

Yes, it’s long past time. Unfortunately, many people and businesses are still using WPA and sometimes even WEP encryption. With WPA, you’re vulnerable to sharing your network with strangers, using common passwords that are easy to hack, or switching your WiFi to public…
