Embroidery is constructed (mostly by women) in hundreds of tiny stitches which are visible on the front of the fabric. The system of the stitches is revealed on the back of the material. Some embrioderers seal the back of the fabric, preventing others from seeing the underlying structure of the pattern. Others leave the back open for those who want to take a peek. A few integrate the backend process into the front of the fabric. The patterns are shared amongst friends in knitting and embroidery 'ciricles'.
Software is constructed (mostly by men) in hundreds of tiny pieces of code, which form the hidden structure of the programme or interface. Open Source software allows you to look at the back of the fabric, and understand the structure of your software, modify it and distribute it. The code is shared amongst friends through online networks. However the stitches or code only make sense to those who are familiar with the language or patterns.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
