WordPress change domain names

By admin on January 31, 2014 in Word Press

Well I thought it was time to change domain names hosting my blog WordPress site. Hello from davidhill.co and goodbye virtual-blog.com So why did I make this decision? I certainly haven’t taken it lightly. Moving Domain Names is challenging and requires a lot of thought and pre-planning. However, I wanted to have a blog site that was more relevant to me personally, rather than just purely virtualisation. My old domain name just didn’t fully reflect the content anymore. I was able to purchase davidhill.co when they released the .co domains with the intention of switching. Now I have finally bitten the bullet and gone ahead with the migration.

This is a really good […]

Rebranded and renamed

By admin on January 31, 2014 in Randomness

Hello from davidhill.co and goodbye virtual-blog.com I have decided to rebrand and rename my blog site to better reflect me and what I write about. Not everything I write about is virtualisation and felt that beginning 2014 it was time to finally move over. As you may notice, not everything is working as expected. Some of the plugins are crashing the site, and have had to be disabled. Fancybox (the image popup) is having some issues for example. Please bear with me while I resolve the issues and get everything working. Once everything is completed and fully working, I will be writing a lessons learned post for anyone else considering undertaking a domain name change.

Question: Can you use Multicast within Cloud Environments? I got asked this question the other day on the Q&A for the Virtual VMUG. Their question was “could they use Multicast within Cloud environment?” specifically vCHS. The short answer yes you can but it depends 🙂 The Long Answer Lets initially look at what Multicast is, this is an excerpt from Wikipedia: In computer networking, multicast is the delivery of a message or information to a group of destination computers simultaneously in a single transmission from the source. Copies are automatically created in other network elements, such as routers, but only when the topology of the network requires it. IP multicast is a technique for one-to-many communication over an IP infrastructure in a network. It scales to a larger receiver population by not requiring prior knowledge of who or how many receivers there are. Multicast uses network infrastructure efficiently by requiring […]
