• The testament of a furniture dealer (07 Aug 2015)

  On December 20th 1976, Ingvar Kamprad (the legendary owner of IKEA) wrote a ‘testament’ outlining his views on business and life. I’m baffled to discover how much insight he already gave away in 1976. The 16-page document contains at least as much wisdom as the last 5 business books I read. I found analogies with the lean startup method, toyota production, writings of Paul Graham and general life advice. What a wonderful document, no wonder Ingvar was so successful!

This relatively new movement has a number of concepts at its core that us security folks could (ab)use. ‘Automated testing’, ‘infrastructure-as-code’ and ‘continuous integration or delivery’ help teams rapidly introduce new functionality by quickly detecting bugs and providing a clearly defined, automated and scalable infrastructure environment.

• Opportunities to use monoids (17 Feb 2014)

  Recently, I was watching this talk by Avi Bryant where he talks about using algebra in programming. The talk is geared towards distributed systems, but I think the concepts are applicable in general. Certainly when I realised that my earlier trouble also concerned monoids.. So, what’s to gain from understanding this algebra? At least improved code reusability and parallelism. And an opportunity to satisfy your curiosity!
