How Not to Rollout New Ideas, or How I Learned to Love Testing

I was recently reading an article in TechCrunch titled “The Problem With The Internet Of Things,” where the author lamented how bad design or rollout of good ideas can kill promising markets. In his example, he discussed how turning on the lights in a room, through the Internet of Things (IoT), became a five step process rather than the simple one step process we currently use (the light switch). This illustrates the problem between the grand idea, and the practicality of the market: it’s awesom...

The Advantages and Disadvantages of Network Monitoring

Implementing network monitoring for organization is not something new for large enterprise networks; but for small to medium sized businesses a comprehensive monitoring solution is often not inside their limited budgets. Network monitoring involves a system that keeps track of the status of the various elements within a network; this can be something as simple as using ICMP (ping) traffic to verify that a device is responsive.
