How does Internet work - We know what is networking
Routing table will then leave to the switching process the job of load-sharing. That is, route-cache mechanisms like CEF on Cisco device will do load-share per session using source-destination IP.
When writing a blog post about a technical topic, I often capture a lot of screen shots that I need to edit before adding them to my blog article. Usually I want to add a border around each image and I sometimes want to reduce the size of images that are too large. I want to do this quickly and easily so I use ImageMagick, an open-source command line image editor.
It takes too long to edit a large number of images one by one in an image editor like Photoshop or Gimp. Using ImageMagick makes it easy to batch process all images in a folder by entering a simple command. You may also incorporate ImageMagick into shell scripts, batch files, or other programs to automate the preparation of images for your blog.
ImageMagick is a powerful image manipulation tool with an intimidating set of options and subcommands. However, most bloggers will use only a few simple options. In this post, I will show how to install and use ImageMagick to perform the simple image conversions bloggers typically need. I will show how this can be done on each of the major operating systems: Linux, Windows, and Mac OS X.

I had the opportunity to attend this year’s Gartner Data Center Infrastructure and Operations Management Conference in Las Vegas December 7th – 10th. The sessions were very informative, providing insight into both high-level trends and tactical topics, including bimodal IT, cloud (both public and private) and converged/ hyperconverged infrastructure. I leveraged Twitter at the conference as a means of taking, and sharing, copious notes (@RobertNoel3). Here’s a look at the conference’s main themes:
Bimodal IT:
Bimodal IT is a topic that Gartner has been discussing at length in recent years. The concept of bimodal IT is that organizations need to behave in two modes simultaneously (mode1 and mode 2). According to Ray Paquet, Managing VP at Gartner, mode 1 is predictable where orders are taken from customers of IT and delivered upon. This is the process of “keeping the lights on” and supporting legacy tools and processes. Mode 2 is exploratory where new tools and processes are considered hand-in-hand with customers of IT. Mode 2 is all about moving fast and taking risks as a means to support the agility required for the next generation of IT. As a metaphor, Paquet described mode 1 Continue reading
