]]> Not all wireless networking is the same. In this short tutorial I cover the various different speed and frequency ranges that different networks can use. When setting up a wireless network you need to make sure that all of your components are compatible.

]]> Just because a computer isn’t connected to the internet doesn’t mean that you don’t need an anti-virus program. Here’s how you can keep its anti-virus up to date by using a computer that is connected to the internet to download the updates to copy across.

]]> Even when you tell Windows to always show file extensions that doesn’t necessarily mean that you will actually get to see all file extensions. There is a registry value for file extensions that can prevent their appearing even when asked to always show them.

So how do we fix the Completely Hidden File Extensions so as to make them visible as well?

]]> While escaping your data can potentially be as secure as keeping it separate, it isn’t always so in practice. People make mistakes and one possibility if you just escape data is that someone amending the code for some completely separate reason will accidentally remove the code to escape some of the data. This can’t happen when the data is kept completely separate.

Make your mySQL code more secure by using prepare and bind statements to Keep Data Separate from the SQL.

]]> The new version of XHTML being developed alongside HTML 5 is XHTML 5. Since Internet Explorer 5 is the last browser to not understand XHTML and it doesn’t understand HTML 5 either, XHTML 5 will be the first version of XHTML to become usable at the same time as the equivalent HTML version does.

This XHTML 5 Template provides a starting point for coding pages using XHTML and points out some of the differences from HTML 5 and earlier versions of XHTML.

]]> I often see requests for help from people claiming that their alt tag doesn’t work in Firefox. This statement of course makes no sense whatsoever and just shows that the person has made two mistakes. Firstly they have confused their terminology as it is an attribute and not a tag and secondly they have misunderstood what the attribute is for.
