Libcurl gets a URL API
libcurl has done internet transfers specified as URLs for a long time, but the URLs you'd tell libcurl to use would always just get parsed and used internally. Applications that pass in URLs to libcurl would of course still very often need to parse URLs, create URLs or otherwise handle them, but libcurl has not ……

Why not program right?
(Originally published on CACM blog.) Most of the world programs in a very strange way. Strange to me. I usually hear the reverse question: people ask us, the Eiffel community, to explain why we program our way.

Gradual Programming
Programming is a fundamentally incremental (or gradual) process, and our programming languages should reflect that. I show several ways in which program models transition over time and discuss how future research can further a human-centric vision for programming languages.
