Two sad departures today that reinforce the march of time.
Firstly the news that the BBC's Ceefax is no more - due to the final switch from analogue to digital TV. Ceefax was a technical wonder of the 1970s - an era of teleprinter and punched card. It survived all the way into the internet age - teaching web editors how to keep copy short and to the point.
The other sad loss is of Flight Lieutenant William Walker - the last of the few. As is usual on these occasions the Telegraph provides an excellent obituary.
His poem 'Our wall' adorns the memorial to the 2,937 aircrew who died during the Battle of Britain - helping to defeat tyranny and ensuring that innovations like Ceefax would be put to peaceful use in future years.
