My nephew James came up with this; I think it’s great:

Here’s my attempt to follow his lead, less successfully, I think!

Not sure of the origin of this – a cousin sent it to me…

A super response

December 14th, 2013

We were talking at lunch today about the foolishness of that old interview question:

“What would you say is your biggest weakness?”

Several people proposed suitable responses, but my favourite came from Richard. His suggestion?

“Kryptonite”

Bless you

I was telling Rose about a small photographic accessory that plugged into the hotshoe.

“The what?”

“The hotshoe.”

“That’s what it’s called? I thought you sneezed.”

Quantum Qonnection

This has been doing the rounds on the net for a while – to the extent that I’m not sure who deserves the original credit. But it’s very nice.

Circles of logic

I cycle past this sign regularly:

I think this indicates that all of Cambridge is now part of the Cavendish Lab. I know they’ve been expanding a lot recently, but I didn’t realise they’d got that far.

On the other hand, I may be confused. It’s difficult to keep a clear head when you’re cycling backwards like that.

This, I think, is quite fabulous. A jazz rendition of the Dr Who theme, by Bill Bailey.

Goldilocks for grey-haired geeks

April 20th, 2013

When I was an undergraduate studying Computer Science, in the late 80s, the course was accredited by the British Computer Society on the condition that, as part of the syllabus, we were taught some COBOL. For those who have not encountered it, COBOL – the Common Business Oriented Language – is a very early programming language designed with the idea, amongst other things, that managers and other non-technical business types should be able to read and understand it.

In retrospect this wasn’t really a great idea (any more than it was when Apple tried something similar with AppleScript in 1993). Computer languages tend to get a kind of uncanny valley problem when you try to pretend that machines speak the same way as humans; the results are neither good English nor good programming languages. It’s a bit like Franglais, except that Franglais is enjoyable to use.

But COBOL can be forgiven; this was after all still 1959, and the world’s experience in programming languages was somewhat limited. It was designed by people as eminent as Grace Hopper (who was brilliant at handling David Letterman, as well as computers!). And COBOL was incredibly successful – for some decades it was the most-used computer language, and it’s still in use today, though it’s bizarre to discover there are people doing .NET programming with it.

Anyway, it was Dr Frank King who taught us most of our languages, and since he had to include a bit of COBOL, he did it mostly as a joke, starting with a properly-constructed “Hello World” program, which I seem to recall was 77 lines long.

At the end of the final lecture, he handed out photocopies of “The Common Business Oriented Goldilocks”, which had been published in Datamation magazine back in 1968, and which is written in something approaching valid COBOL. Maybe it is valid COBOL… I never wrote another line of COBOL after that lecture, so don’t remember. But I may have readers who do!
