Cheat Sheet: Virtualisation
Cheat Sheet If it's virtual it can't do anything useful in the real world, can it? Just because you can't reach out and touch something doesn't mean it isn't real - or extremely useful to businesses. A lot of companies turn to virtualisation when they want to... [04 Jun 2007]
Cheat Sheet: The $100 laptop
Cheat Sheet It's green and has a handle - is it a watering can? No, it's the $100 laptop. There's no hard disk but it will have four USB ports and wireless broadband that can mesh network. According to MIT Media Lab, it's because monitors are getting cheaper. [29 May 2007]
Cheat Sheet: Wi-fi
Cheat Sheet Since the turn of the century, wi-fi hotspots have really taken off and it's almost impossible now to find a public place or office that doesn't offer wi-fi access. Bit pricey though isn't it? But it's not all about access out and about, is it? [24 May 2007]
Cheat Sheet: FTTx

Cheat Sheet: Blade servers and PCs

Cheat Sheet: Six Sigma
Cheat Sheet First, IT vendors, especially hardware manufacturers (though there is definitely a role for it in software development too), use Six Sigma. No, that's where we hear about it most. Well, it's a quality assurance methodology employed by plenty of... [30 Nov 2006]
Cheat Sheet: The Computer Misuse Act

Cheat Sheet: Open source licences
Cheat Sheet I'll know it's open source because it's free, right? When using open source in an enterprise, find out which licence the software is released under, and whether or not it's a dual licence, and then do your homework (or hire a lawyer) to make sure... [20 Nov 2006]
Cheat Sheet: BT's 21CN
Cheat Sheet The whole 21CN project will cost the telco in the region of £10bn to finish off and it hopes to save around £1bn a year as a result. It's also one way for BT to jump on the VoIP trend, which is giving its traditional fixed-voice revenues a kicking... [14 Nov 2006]
Cheat Sheet: Second Life
Cheat Sheet Some just like to use Second Life as a place to hang out with friends, but others are using it as a new land where they can set up business. Love it! It's probably the best known of the virtual worlds that are becoming popular but are distinct from... [09 Nov 2006]
Cheat Sheet: Prince2
Cheat Sheet Essentially it is a methodology that uses a set of best-practice guidelines to help managers deliver projects on time and within budget. Well it all sounds good, common-sense stuff. Can anyone just use it or do you need a qualification? [07 Nov 2006]
Cheat Sheet: Software as a service
Cheat Sheet This is because it is hosted by the service provider, rather than being installed on your own PC, or within your own office. Internet access is pretty ubiquitous now but it can't be taken for granted. [31 Oct 2006]
