Backus on Von Neumann at the Turing Award

Can Programming Be Liberated from the von Neumann Style?

On a pre­vi­ous post, we talked about Von Neumann’s Turing Complete mod­el for a com­puter. A CPU, some Memory, and I/O. It was beau­ti­ful, but it had its dis­ad­vant­ages, and an unfor­tu­nate leg­acy. Today, John Backus will lead our jour­ney through these mat­ters. Enter Sandman: Backus 32 years later, a thor­ough cri­tique was addressed, iron­ic­ally, […]


Intaglio and relief print­ing are two com­plete oppos­ites in my prac­tice. I greatly admire those who man­age to con­vey tex­tures in a wood­cut (e.g. sheets like this by Klaus Magnus: Berlin façade, 1973), but so far I fail to go very far bey­ond out­lines. This lim­it­a­tion makes my relief prints the by far most con­cep­tu­al […]

Travels in pictures – part II

Starting from scratch, what bet­ter way to learn intaglio print­mak­ing than to pro­cess the pre­vi­ous trip draw­ings? Their tech­nic­al and styl­ist­ic vari­ety was such that I’d have to try the entire spec­trum of etch­ing tech­niques.
