Who David Heidelberg is
David Heidelberg works on Linux for phones, with Phosh, the GNOME-based mobile shell, after years in the mobile Linux community around postmarketOS and Mobian and on Mesa CI and GPU drivers at Collabora.
The conversation
David Heidelberg recorded a conversation with the show at Open Source Summit Europe 2026, Prague, on 8 October 2026. It is about a phone that runs no Android at all: the mainline Linux kernel, the Phosh shell, GNOME apps and Debian packages, shown together with Petr Hodina. Who else the show met that week is in the write-up of Open Source Summit Europe 2026.
Phosh
Phosh is a graphical shell for Linux phones, built on GNOME technologies; Phosh.mobi e.V., a registered non-profit, represents the project. Everyone the show has interviewed there is listed on Phosh on Udienza.
