What TDD means to me…

It was about 19 years ago now that a colleague of mine lent me a copy of a little white book. That book changed the way I looked at programming more than any other book (though The Pragmatic Programmer gave it a run for its money). One of the things, in particular, was Test Driven Development, or TDD.

The Commonwealth Bank lost 10 years of banking records

As reported on BuzzFeed, the Commonwealth Bank of Australia lost backup tapes holding ten years (2004-2014) of banking records for up to 12 million customers. If you’re a customer of the Commonwealth Bank, and haven’t already been turned off by the stories coming out of the Royal Commission, then you should take this as the last straw and change banks.

Blog-A-Day May

It has been literally years since I’ve blogged on anything resembling a regular basis. This hit me recently when I renewed my WordPress subscription, and then again today when I renewed my DNS domain. I’m just not blogging enough – even for myself, and I’m the primary audience. So – I’m going to post every day in May. A #BlogADayMay.

As usual, I’m blogging for myself. If other people find my rambling ruminations regarding reality interesting, or even of benefit, that’s great, but it’s a bonus, not the goal. The topics for this month will be wide and varied. Posts will range from short to long, because I don’t have an internal editor, and will write until I run out of things to say or time to say it in. Once May is over, I may continue, or I may go back to my irregular posting.

You have been warned.
