If you been reading the articles in ME, but (like me) are too tight to pay for MS Word, this tells you how to do it in Libre Office. Dead easy, just did it and it worked straight out of the box

Thats a very interesting link. Thanks for sharing it.

Mind you, I would be interested in trying to read these codes by eye. Many years ago, when we introduced warehouse scanners into the business, I could read certain bar codes by eye, but I wouldn't know where to start on a QR code.

SNIP!

My first 'proper' job was working with a team supporting a large analogue ('analog' ? ) computer. One of the mathematicians could read 8-hole punched paper tape by eye. He used to sport a neatly furled umbrella – some of our colleagues filled his umbrella with chad!.

I belong to several groups of our local U3A including an IT-related group. As part of Covid 'track & trace', one of the 'Computer Gurus' was asked to select and buy a scanner to use on the bar-coded membership cards of attenders at face-to-face meetings. He told me that the scanner would also scan QR codes and that the User Instructions were a single A4 sheet bearing several QR codes!!!

Best regards,

I was chatting once to the Chief Engineer of a large UK electronics comany who started his career at EMI. He worked in a tiny office on the top floor of the research department programming an early computer using punched tape. Always had a problem with the chads as they wouldn't provide a wastepaper basket, so he resorted to emptying them out of the window. This solved the problem until he was called into a senior manager's office of the records division (which made all EMI's money) – on his desk was an LP record with lots of tiny bits of paper embedded in the vinyl. Turned out there was no filtration on the cooling air intakes of the record pressing line… The great days of UK technology.

My father could read punched telex tapes. It is just pattern recognition so you could learn it – we just happen to have learned the squiggles we call written English. Arabic, Korean, Chinese just completely different squiggles. Like reading Morse code by sound or vision.

I would be possible to bring up a child so they thought verbal communication was done in Morse code and reading was barcode or QR code.

One thought is how long the standard will persist in our rapidly changing digital world. Will these go the same way as VHS tapes and be a problem to read in ten years? NFC tags are an alternative.

Ah, those were the days, 5 hole tape, 8 hole tape, sticky patches to correct miss punched tape, Friden Flexowriters, Teletype ASR 33s. Would you believe that some of the early Concord(e) wind tunnel results were run through Pegasus analogue computers and the 5 hole output paper tapes read by eye and then plotted on graph paper for the Aerodynamics Office.

Oh,  and those punched chads – we used them as confetti and they got everywhere !

Anyone remember the foot ball results coming through on a Saturday afternoon … Tac tac tee tac as each letter arrived at the teleprinter – Oh such excitement !

 

Thanks Michael, I will have a read of that link later.

John,

Re EMI quote.

The wind must have been blowing very hard, that's a distance of at least 200+ M, even if the source was on top floor and the record press plant was at ground level two roads away.

Duncan you posted this just at the right time for me thanks
