A few months ago, British Airways' customers had their credit card details stolen. How was this possible? The best guess goes something like this: BA had 3rd party JS on its payment page <script src="https://example.com/whatever.js"></script> The 3rd party's site was hacked, and the JS was changed. BA's customers ran the script, which then harvested their… Continue reading →
Scratching my own itch here... GitHub users have a username (mine is @edent) and have a user ID number (mine is #837136). If you want to redirect a user ID to a username, you can use the little service I've cobbled together: https://edent.github.io/github_id/#837136 That will take your browser to my GitHub page, using nothing but… Continue reading →

As Liz… Continue reading →
How much checking do we perform that our code is running as intended? I found a curious bug this weekend, which made me think about some of the assumptions that we use when programming. Imagine sorting an array using JavaScript. var arr = [10, 5, 66, 8, 1, 3]; arr.sort(); So far, so normal. Create… Continue reading →
In 2009, Kosso and I petitioned Twitter to allow us to search for Tweets by their "in reply to" ID. The idea was that developers could created a properly threaded view of conversations. Of course, Twitter being ultra-responsive to developers, did absolutely nothing. Skip three years into the future, and App.net is providing all the… Continue reading →
Ahhhh! The BBC. Shining bastion of purity in a sea of commercial malaise. Nothing can spoil its lustre. Well, for those of us in the UK. For the poor sods who find themselves living in the wilderness of ROW (Rest Of World) this is their BBC experience... The reasons for me seeing this are rather… Continue reading →
