Geoff said "But ... about the defibs:- that's why it's best to keep them on "crash" carts!"
Is there an app for that?
I was looking back to see if she was looking back to see if I was looking back at her!

I have a slide rule* sitting under my monitor with a note on it saying "In case of network or power failure". However its database and spreadsheet functions are not as good as the PC's.
Technology does move on and so does our reliance on it.

* And I know how to operate it!!!
It is a fancy one with log log scales as well as the normal ones and on the back it has L & C and frequecy & resistance scales.
My spelling is not bad. I am typing this on a Medigenic keyboard and I blame that for all my typos.

Man after my own heart. I still have a "British Thornton" slide rule though I must confess I have long forgotten how to use most of the functions. My sister in law told me many years ago of having a cylindrical slide rule, something I would like to have a play with I must confess. Great tools and no need for batteries

One of the great things about the slide rule is that you need to already know the magnitude of the answer. That is, you need to have an idea in advance what sort of answer you are expecting. And often enough (in my experience anyway), that is all you actually need. 
If you don't inspect ... don't expect.

In preparation to using the slide rule, I was taught estimating the magnitude of the answer, and I agree Geoff, that was one of the most useful things I ever learnt in math’s class!

If anyone is that interested the slide rule is:
The Nelson-Jones Circuit Designers Slide Rule designed and marketed by KEY Electronics of Bournemouth and its copyright date is 1974. How many calculators etc will still be functioning in 37years time?

A friend's dad had a Rockwell 8R calculator from about that date and I bet someone out there has a still functioning one?

My father still has the Casio calculator he took to Uni, working fine. And the guys in the workshop here have another of the same model.
I love deadlines, I like the wooshing sound they make as they fly by.

So - would the ludites reunited reinvent the wheel every time you needed a processing unit be it in a ventilator, infusion pump, CD player or computer - Or would you as I expect take a common processor and write code for it to perform the functions you need of it? After all we sort of do this with power supplies.
