Cnet has an article on the design of the Google servers [1]. It seems that their main servers are 2RU systems with a custom Gigabyte motherboard that takes only 12V DC input. The PSUs provide 12V DC and each system has a 12V battery backup to keep things running before a generator starts in the […]

Flame has written some ideas about building Linux Powered Battle Droids and demonstrating them [1]. It seems to me that the biggest problem with having a battle of a similar nature to Robot Wars [2] is creating a safe arena. Getting an area the size of a basketball court fenced off with bullet-proof plastic is […] A client is considering some options for serious deployment of some CPU intensive work. The options that are being considered include cloud computing (Amazon EC2 [1]), virtual machines (Slicehost [2] and Linode [3]), and purchasing servers to install in racks at various locations. I can’t disclose the criteria that will determine when each of those […] When reading a magazine I often see an advert for a product that I want to buy (or recommend that a client buy). This is of course expected as the advertisers put a lot of effort into targeting their adverts to the people who read such magazines. However I often decide that I want to […] Recently there has been increasing attention paid to thermal issues. The power used by computers not only impacts the electricity bill (and battery life for a portable device) but is a cooling problem. The waste heat from desktop systems and servers costs energy (and therefore money) to remove by the air-conditioning system and the heat […] Since about 2002 I have been using a iPaQ [1] for taking notes while on the move. I have a pair of H3950 iPaQs that were given to me for the purpose of some software development work. As modern mobile phones have telephony as a small part of their feature set I think it’s worth […] I have never felt inclined to create content for Youtube due to the low resolution of the display and the fact that only one format is supported (Flash which is totally non-free). The existence of blip.tv has inspired my interest in creating videos for distribution on the net. blip.tv has higher resolution than Youtube and […] Six months ago I investigated the options for Xen virtual servers [1]. I ended up receiving an offer of free hosting and not needing that, but the research was useful. There is a good range of options for Xen servers with different amounts of CPU power, RAM, bandwidth, and disk space. There are a couple […] One significant dividing factor between mailing lists is the difference between summary lists (where the person who asks a question receives replies off-list and then sends a summary to the list) and the majority of mailing lists which are discussion lists (where every reply goes to the list by default). I have seen an argument […] |
