RISC OS RC 8 Released

By admin on March 25, 2013 in RISC OS

They are coming thick and fast at the minute, the latest update to RISC OS for Raspberry PI is available for download now. This page contains links to SD card images for various operating system distributions. The minimum size SD card you can use is 2GB, but it is recommended to get a 4GB SD card or above. For each distribution, we provide both a direct HTTP download, a torrent file and a SHA-1 hash; the total number of concurrent direct downloads is limited, so we encourage you to use the torrent file if at all possible. It’s helpful to us if you download the torrent from this page, because it means we can see how many downloads are going on and use that to make rough predictions about sales. If you’re a total beginner and the above paragraph makes no sense at all to you, please come to the […]

Michael Owen to retire – my farewell

By admin on March 20, 2013 in Randomness

I have read the news today that Michael Owen is going to retire at the end of the season in May. BBC Sport reported here. To begin with, this post has nothing to do with Virtualization or technology in any way but I felt the need to publish my thoughts on this special football player. Former England striker Michael Owen is to retire from football at the end of the season. Owen, 33, who scored 40 goals in 89 internationals, played for Liverpool, Real Madrid, Newcastle United and Manchester United and is now at Stoke. He said: “It is with an immense amount of pride that I am announcing my intention to retire.” Now this makes me feel old today. I have grown up with watching Michael Owen in an England shirt. He was awesome. I actually got to see him play at Wembley in 2007 against Russia when he […]

vCloud vApp Design and Use Case – Part 2

By admin on March 14, 2013 in Cloud Computing

This article is part 2 of my vCloud vApp design considerations and use cases definition. Part 1 can be read by clicking here. In this article we will look at the logical design of vApp use cases. I have spoke about these in the past in my vCloud Director Networking 101 post, but never really spoke about the specific use case. Use Case 1 – vApp Network Isolated This use case would primarily be used for development and test scenarios, where there is a requirement for vApps to be completely isolated. In this scenario multiple vApps of the same configuration can be deployed without risk of conflict, since there is no external connectivity available and all network traffic within the vApp is isolated at Layer 2. The characteristics of these vApps are: VMs are connected together on isolated vApp networks No connectivity between multiple vApps or to organization networks Same configuration can […]
