Simply Jonathan

A 4-bit Calculator Made in Cardboard and Marble 

This is amazing.

One of my favourite books is Charles Petzold‘s Code. This seems like something straight of the early chapters, it’s fantastic.

This is Simply Jonathan, a blog written by Jonathan Holst. It's mostly about technical topics (and mainly the Web at that), but an occasional post on clothing, sports, and general personal life topics can be found.

Jonathan Holst is a programmer, language enthusiast, sports fan, and appreciator of good design, living in Copenhagen, Denmark, Europe. He is also someone pretentious enough to call himself the 'author' of a blog. And talk about himself in the third person.
