I’m a Python and Django web developer, Ubuntu Member, Ask Ubuntu Moderator. This is my personal blog where I get over-excited about a whole raft of different topics, mostly technical.

Please be careful with my daughter's biometrics

Schools often aren’t the most clued up when it comes to understanding privacy and security, but the companies and service providers that that work with them —and take on all sorts of child data— really need to watch what they’re doing.

Nobody should be handing out my daughter’s fingerprints to strangers, right?

When did we stop caring about basic network security? We need to act before it's too late.

Python isn't always slower than C

It's time we buried Internet Explorer 8

Every web developer loves to wail on Internet Explorer but we need to act now if we want to stop the history of IE6 repeating itself with IE8. The longer we don’t, the longer we agree to limit ourselves to not using new and exciting features that make the internet better and our lives easier.
