Distributed computing is a method of computer processing in which different parts of a program run simultaneously on two or more computers that are communicating with each other over a network. Distributed computing is a type of segmented or parallel computing, but the latter term is most commonly used to refer to processing in which different parts of a program run simultaneously on two or more processors that are part of the same computer. While both types of processing require that a program be segmented—divided into sections that can run simultaneously—distributed computing also requires that the division of the program take into account the different environments on which the different sections of the program will be running. For example, two computers are likely to have different file systems and different hardware components.
An example of distributed computing is BOINC, a framework in which large problems can be divided into many small problems which are distributed to many computers. Later, the small results are reassembled into a larger solution. Continue reading ‘Distributed computing’
There have been a few people asking for links to a couple of desktop pictures I have posted on flickr. Unfortunately I don’t have the links anymore or even remember where I got them. However, I do still have the files.
I’m sure that just about everyone will know this but for the two or three people that don’t, just use the “Save link as” command to download the images of your choice.
So here they are…

I’ve used Mac mini’s a lot in my business and personal life. It’s great to be able to put such a small Mac wherever you want it and they rarely if ever have any problems.
In fact the only problem I’ve ever had with them is that they can end up getting a bit dirty especially if one has pets such as cats or dogs around.
When this 1.33GHz model tarted having some stability issues I disassembled it and cleaned it. The heat sink was almost completely blocked by a combination of hair and dust that fell away during disassembly.
iMac DV (Slot Loading), Code Name: “Kihei, P7″
Recently acquired this iMac is in perfect working order with the exception of some very severe burn in on the CRT, thankfully I just happen to have a spare CRT in waiting.
