The only reason for this post is to hold some images I’m using elsewhere. If you find it useful for some reason I would be real surprised.

Processor model numbers are used to distinguish between microprocessors with different sets of features and different characteristics, such as speed, level 1 and level 2 cache, etc. The model numbers can be used to identify only basic features and most important characteristics, and may not be used to identify all features/parameters of the CPU. For example, model numbers never identify CPU ID, core stepping, core voltage, maximum CPU temperature and a few other parameters. If you need to find out all details on specific processor please use sSpec numbers for Intel processors or order product numbers for AMD microprocessors.
For more information on Intel model numbers please see Intel processor (model) numbers.
For more information on AMD model number please see Athlon XP, Athlon 64, Sempron and Turion model number and Opteron model numbers.
This post is just to show the images and some additional information for a few items I have decided to part with. If you have any questions please refer to the listing that led you here. Sorry but I will not be answering questions from here.
Tabbed browsing is usefull enough on it’s own, but there are a few simple tricks that make it even more so. I find that the most useful trick for me is to open the previous page in a new tab. This is done by simply holding down the “Command” key while clicking the back button (or selecting back from the contextual menu).
This also works with the forward button. Any link you click on can be opened in a new tab by holding down command when you click the link. If you want to view an image in a new tab follow the same pattern with the “View Image” or “View Background Image” commands accessed via a right click or a “Control” click.
Inline linking (also known as hotlinking, leeching, piggy-backing, direct linking, offsite image grabs and bandwidth theft) is the use of a linked object, often an image, from one site into a web page belonging to a second site. The second site is said to have an inline link to the site where the object is located.
Inline Linking and the HTTP Protocol
The technology behind the World Wide Web, the Hypertext Transfer Protocol (HTTP), does not make any distinction of types of links-all links are functionally equal. Resources may be located on any server at any location.
When a web site, such as Malagent’s Sandbox, is visited, the browser first downloads the textual content in the form of an HTML document. The downloaded HTML document may call for other HTML and/or stylesheet files to be processed. These files may contain <img> tags which supply the URLs which allow images to display on the page. The HTML code generally does not specify a server, meaning that the web browser should use the same server as the parent code (<img src=”picture.jpg” />). It also permits absolute URLs that refer to images hosted on other servers (<img src=”http://www.example.com/picture.jpg” />).
When a browser downloads an HTML page containing such an image, the browser will contact the remote server to request the image content. Continue reading ‘What is Inline linking?’
Mean time between failures (MTBF) is the mean (average) time between failures of a system, and is often attributed to the “useful life” of the device i.e. not including ‘infant mortality’ or ‘end of life’ if the device is not repairable. Calculations of MTBF assume that a system is “renewed”, i.e. fixed, after each failure, and then returned to service immediately after failure. The average time between failing and being returned to service is termed mean down time (MDT) or mean time to repair (MTTR).
It's just a matter of time.
Mathematically, the MTBF is the sum of the MTTF (mean time to failure) and MTTR (mean time to repair). The MTTF is simply the reciprocal of the failure rate, Continue reading ‘Mean time between failures’
Mac OS X version 10.4 "Tiger" is the fifth major release of Mac OS X, Apple’s desktop and server operating system for Macintosh computers. Tiger was released to the public on April 29, 2005 as the successor to Mac OS X v10.3 "Panther", which was released 18 months earlier, and was superseded by Mac OS X v10.5 "Leopard" on October 26, 2007, after 30 months, making Mac OS X v10.4 the longest running version of the Mac OS X operating system. Some of the new features include a fast searching system called Spotlight, a new version of the Safari web browser, Dashboard, a new ‘Unified’ theme, and improved support for 64-bit addressing on Power Mac G5s. Mac OS X x10.4 "Tiger" was included with all new Macintosh computers, and was also available as an upgrade for existing Mac OS X users, or users of supported pre-Mac OS X systems.
The server edition, Mac OS X Server 10.4, was also available for some Macintosh product lines. Tiger is also the first version of any released Apple operating system to work on Apple-Intel architecture machines (Apple machines using x86 processors.) The Apple TV, as released in March 2007, ships with a customized version of Mac OS X v10.4 branded "Apple TV OS" that replaces the usual graphical user interface with an updated version of Front Row. Six weeks after its official release, Apple had delivered 2 million copies of Tiger, representing 16?% of all Mac OS X users. Apple claimed that Tiger was the most successful Apple OS release in the company’s history. At the World Wide Developers Conference on June 11, 2007, Apple CEO Steve Jobs announced that out of the 22 million OS X users, more than 67?% were using Tiger.

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’
Mac mini (Late 2005) Processor Heatsink
Originally uploaded by malagent
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.
