Today is the official launch of the Raspberry Pi, an ambitious UK project to create low cost computing with the aim of bringing a proper understanding of computing back to education.  The device is itself is a fully fledged computer the size of a credit card with external USB and HDMI connectors.  What’s remarkable about Raspberry Pi is the price; there are two versions, Model A and Model B (echoing the BBC Micro options from 30 years before), selling at a target price of $25 and $35 respectively.  The extra $10 for the model B gets you a fixed Ethernet connection and an additional USB port. The launch of what could be a milestone in computing has been made with usual British aplomb and understatement; the static website that replaces the previous one at www.raspberrypi.org talks about how the staff monitoring their Twitter account will be in the pub from 6pm onwards...

Amazon Delivers Cloud Archive Storage with Glacier

At the end of August 2012, Amazon Web Services released their latest service offering – a long-term archive service called Glacier.  As a complement to their existing active data access service S3, Glacier provides long term storage for “cold” data – information that has to be retained for a long time but doesn’t require frequent access.

Is the Performance of All Cloud Servers the Same?

One of the benefits of delivering Infrastructure as a Service (IaaS) through the cloud is an abstraction from the underlying hardware delivering the service.  There’s no requirement to understand what technology is being used to deliver, for example, cloud servers.  The specification of a cloud-based server is based on a few simple metrics, CPU, memory and disk space. CPU or processor power is described by most vendors in terms of cores, which translate to some abstract definition of physical computing power.  Only Amazon Web Services (AWS) reference physical CPU architecture, w...

So.cl and Google+ Musings for a Monday

This morning I signed up and had a play with Microsoft Labs’ social media application, so.cl.  This was quietly released over the weekend with little attention as it’s a piece of experiment work rather than a new social media platform.  It’s early days to be commenting on whether so.cl will be useful; currently it appears to be targeted at students and search sharing.  I wonder whether the intention is to use the output to help improve the quality of Microsoft’s search engine, Bing. Anyhow, the so.cl interface is reminiscent of Google+ (especially party invitations, that seem to... (more)
