Is C++ Turing Complete?

October 20–21 · Tel Aviv · 60 minutes

Six different computational worlds inside C++ go on trial—from ordinary runtime code and templates to constant evaluation, CTAD, the preprocessor, and an intentionally strange contracts machine. The main path stays playful; the complete proofs and their limits sit underneath.

AirTime shows who’s doing all the talking: each speaker’s estimated airtime and who spoke when, analyzed on your iPhone. No transcript, no account. See how it works.

What I do

Coobeeyon is the consulting practice of Michael Daum, a software developer in Toronto. I work directly with clients on hard product and engineering problems. When a project needs more people, I bring in seasoned specialists I trust.

I am especially drawn to rich graphical interfaces, useful artificial intelligence, complex data, and software that has to work in the real world.

Selected client work

A rich 3D application for electrical design, from model conversion and custom rendering to precise editing of generated conduit routes and visual diagnostics.

See more client work, including software for semiconductor testing, human resources, and field-service operations.
