Emulation or virtualization?

admin — Fri, 18 May 2012 06:53:30 +0000

Don’t be confused! Virtualization and emulation aren’t the same. Here’s how they differ.

Emulation is what we do when we try to make one system behave like or imitate a different system. We want to take System A (something we already have) and give it the inputs we would normally use for System B (which we may not have) and have System A produce the same results as System B.

Definition

Virtualization is a buzzword applied to many different technologies: servers, storage, communications, networks. An older, seemingly related term is emulation, but it’s not the same thing. Here, we’ll sort out the differences.

What’s involved is more than a simple translation

A new type of wallpaper, which has been developed by scientists from the “institut polytechnique Grenoble INP” and the “Centre Technique du Papier”, will go on sale in 2013 after a Finnish firm, Ahlstrom acquired the license.

What looks like a bog standard wallpaper roll actually contains silver particles that allows it to filter out up to three different frequencies simultaneously. It is not the first time that such a technology has surfaced. Back in 2004, BAE Systems was tasked by Ofcom to come up with a similar solution based on what was then called a stealth wallpaper.

Do Reputation Management Services Work?

admin — Thu, 22 Dec 2011 06:52:03 +0000

Online reputation is a factor in any online community where trust is important. It affects a pseudonym rather than a person. Examples include eBay, an auction service which uses a system of customer feedback to publicly rate each member’s reputation. Amazon.com has a similar reputation mechanism in place and merchants develop their reputations across different dimensions. One study found that a good reputation added 7.6% to the price received.In addition, building and maintaining a good reputation can be a significant motivation for contributing to online communities.
To begin developing an online reputation, consider how your personal or company brand should be perceived. What is your brand identity / what is your value proposition / selling point / unique voice? Once you have developed the image you would like your constituencies to perceive, develop a strategy to build your brand. Are you seeking credibility in the marketplace (consider blogging, answering questions on LinkedIn), gain market leadership (create innovative tools for your industry) or connection (build a network of contacts in professional and/or social sites).
Once you have begun developing an online reputation it is important to try and protect it. One strategy that many people employ to ensure that they keep up with their online reputation is monitoring. Given the number of sites on the internet, it is impossible to try and manually monitor the entire internet for pages that may affect your online reputation. Tools such as Radian 6 and Google Alerts can help you to keep tabs on your online reputation
