density in comment and analysis
Peter Cochrane's Blog: Wireless jelly
Comment But then there is the density of laptops in the room and wi-fi nodes in the building. It was like wandering around in a vast, variable density and irregular jelly. There are five bars of signal. You're in good shape, being creative, making progress... [13 Jun 2008]
Peter Cochrane's Blog: A petabyte before I die...
Comment Gordon Moore's 1965 observation that the density of transistors on integrated circuits - and hence to some extent computational power - would double every 24 months seemed correct for quite a while. Written in a coffee shop in Ipswich UK and... [14 May 2008]
The greening of IT: Cooling costs
Comment Another key strategy to reduce the cooling load is to scale back the server density. Many vendors are pushing high-density racks requiring 20kW and that also entails water cooling. With density at this level, it would cost more to power the server... [21 Sep 2007]
Editor's Blog: What is city-wide wi-fi?
Comment It is interesting that many people don't mention this isn't free, though with decent density of network nodes you'd be sensible to assume that would never be the case. What is city-wide wi-fi? Probably to each one of us the answer is obvious. [17 Jul 2007]
Data centre in a box
Comment Inside, eight industry-standard 19-inch, 42-unit racks run down either side of the structurally upgraded container, which is supported by a state-of-the-art cooling system to allow for a very high server density. [18 Jun 2007]
Peter Cochrane's Blog: Wi-fi radiation scare
Comment And yet strangely no one has spotted that domestic microwave ovens with faulty doors have a 1,000-fold greater density of radiation than wi-fi - or, even worse, the potential damage to thumbs and fingers that suffer radiation from car keys and... [29 May 2007]
How tech can make us greener
Comment It's fuelled by Moore's Law of transistor density and Metcalf's Law of networks, both of which drive the vicious circle of smaller, faster and more, more, more machines. Though IT is often blamed for not being 'green' enough, there are plenty of... [24 May 2007]
Peter Cochrane's Blog: NGNs - real or imaginary?
Comment While traffic density improved again, the really big win was in signal fidelity and quality of service (QoS). Written on the Ipswich to London train and dispatched to silicon.com via a free wi-fi service in London on the same day [02 May 2007]
Peter Cochrane's Blog: Wi-fi London
Comment During the past few weeks I have completed a wi-fi survey of London in order to get some measure of the node density across a 4km-diameter area centred on Liverpool Street Station. In addition, I mapped a few radial and haphazard routes to get a... [31 Jan 2007]
Peter Cochrane's Blog: Recycling is rubbish
Comment It turns out that I have to dispose of well over 10 years' worth of low-density plastic waste in order to create these bins. In the region where I live we have been equipped with high-density plastic bins so we can pre-sort our rubbish for the... [23 Jan 2007]
Peter Cochrane's Blog: My Christmas wish list
Comment I don't suppose you have something with about 10 times the energy storage density of our current best of the best, do you? Written on BA0048 flying from London to Seattle and dispatched to silicon.com via a free LAN service provided by my Seattle... [20 Dec 2006]
Peter Cochrane's Blog: Is there nothing new in IT?
Comment Advances in storage density, processing power and displays continue at an amazing pace but at the user level it all seems like more of the same but better. Written in a coffee shop on Fleet Street in London and dispatched to silicon.com via a low... [20 Nov 2006]
Peter Cochrane's Blog: Good-bye CDs
Comment So will the DVD share this fate as the next higher density format overtakes it? Relative to the standard CD we will see the density ratio quickly grow from ~3:1 to 6:1 and beyond. Many years ago I gave up using floppy disks because they had become... [14 Jul 2006]
Radioactive: Mobile phones - the battery conundrum
Comment However recent technological improvements have seen their power density grow dramatically and their efficiency improve to acceptable levels. DMFCs were originally developed in the early 1990s but initially found little favour because of their low... [09 Nov 2005]
Peter Cochrane's Blog: Thanks for the memory
Comment We have technologies to continually increase bit storage density for many decades. When I was 29, I was given the job of buying some computer memory. In those days buying any kind of equipment was a big deal - but memory was one of the biggest. [24 Jun 2005]
