A Journal about the experiences I have developing little applications in C#, Perl, Html and Javascript and talking about things new things that I use. Always Geeky; Always Nerdy; Always poor Grammer!

I am a Software Analyst Developer working in Southport, England but living in Liverpool. I develop mainly in C# and ASP.Net. I have been developing comercial software for several years now. I maintain this site (hosted at SwitchMedia UK) as a way of exploring new technologies (such as AJAX) and just generally talking about techie geek issues. This site is developed through a host of Perl scripts and a liberal use of Javascript. I enjoy experimenting with new technologies and anything that I make I host here.

RE: Regex 101 Exercise S2 - Verify a string is a hex number

It turns out I made a little mistake. The regex should be more like ^[A-Fa-f0-9]+$. The "0" problem might be sorted like this ^[A-Fa-f1-9][A-Fa-f0-9]*$.
