This is true for the challenge of proving that cascading stylesheets are Turing-complete, or that you don’t need all those fancy ISA bits of an ARM processors when you already got the LDM and ...

Alan Turing do really describe Mark I/II processor as 'state machine' concepts, and do it like this: ... It is usual to describe it in terms of ‘obeying an instruction’.

TMD-2 has a camera for computer vision of the state machine tiles [Mike] opted for optical character recognition using a Raspberry Pi cam along with Open CV and the Tesseract OCR engine.

Scientists have created the first “chemical Turing machine,” meaning a liquid that can do the calculations that define a classic computer science standard.

He added, “The universal Turing machine naturally exploits what was later seen as the ‘stored program’ concept essential to the modern computer: It embodies the crucial 20th century insight ...
