Getting Things Done (and getting your data out of Cultured Code’s

I’m a big fan of David Allen’s book Getting Things Done. When it comes to effective organization you could probably read this book and be done, it really is that good. One issue I have with the book though is that it’s very paper centric. As a Yard-O-Led fountain pen and Rhodia notebook loving scribbler I have to say I can dig that. I really can.

Spreading your bets on RAID

In the early days of our startup, bubblegum and duct tape seemed to be the order of the day as we struggled to keep things running on cheap as chips computers bought off ebay and a ragtag bunch of borrowed Dell Optiplexes. Developer files sat on their individual machines, source code was scattered across the place and the concept of centralised document storage was a share on one of the developer machines called Common in which everyone dumped their stuff....
