Well this morning my daughter came down with her own Macbook Pro streaming a wireless/radio program. The screen was off and I said to her, "WOW, cool, how did you get that to stream and the screen shut down?"

She replied <with facepalm>, "DAD! It is on screen saver you idiot!"

And lo-and-behold clicking the trackpad brought it up again...

DOH! How long have I been using computers?

<1sf (troll) is finally getting to me. ;oD>

I think it's how long the computers have been using you that's important. Shocked

But it's how long they have been using the kids that is scary.

Still probably easier to use and more efficient than Windows 8.

And with a similar interface. Who'd have guessed that the Windows 8 interface would have been based on such old technology?

Slide rules? Luxury! I started with log tables, and still have a copy.

Did you carve the sums on them with your stone axe or just write with charcoal? [runs away and hides]

Come to think of it, we only got log tables around the 3rd form. Our teachers made us do everything long hand until they were sure we could, then they took pity and issued log tables. I can still do long division and sq roots long hand (but have forgotten much stuff learned later). The sq root was by a kind of long division - not the faster and easier Newton's method. I cannot imagine they teach that stuff today.

Aren't Napier's Bones a slide rule of two scales held together rather than in a captive slide track with cursor? We were not allowed slide rules even at A Level, I only got one at uni. It's still right here in my desk draw [gets it out], an Aristo Studio. Very complex, with no less than 22 scales on it (trig functions, sqrt(1-x*x) etc)!

Napier's bones are a set of rods which lie alongside each other and can be rotated to show different sets of numbers, kind of half way between an abacus and a slide rule.

I recall a lot school work with Taylor series (serieses?) and something called the Newton-Raphson method.

Log, trig and related tables and the trusty slide rule were a great improvement.

Later I enjoyed setting my Sinclair calculator little tasks which involved dividing by zero and watching it cycle through the numbers trying to approximate to infinity. Ah! the joys of numerical algorithms and the halting problem.

Tell you what annoys me now though, jabbing a finger at my PC screen and the darn thing ignores me. Not touch-sensitive, I keep forgetting what the stone age before real tablets was like! Talking of which I got a Bluetooth keyboard for my Nexus 7. Best 20 I have spent in a very long time.

Got a Sinclair ZX81 in Feb' 82 for my 1oth birthday present. I wanted an '8o though, just to be cool because they were white, even though they were not as good. Made me laugh actually, they had a Sinclair ZX81 boxed in Cash Convertors hear a couple of months ago for 39.99 The same price as they were brand knew in Feb '82! Something is wrong there surely? I was gonna buy it, but I've still got my own won! It has a load of electronics on it so that it beeps whenever a keypress (key? it was a membrane) was detected, and another won so can transmit 180 word per minute morse code for the ping shower things in amateur radio. Reminds me Baz, I've got about 5oo single density Amiga disks with software on if you want them. Utils, compilers, Lightwave, word processors, games, demos etc from 91-95 when I sold up and got a pc. The downloads were getting just too big when they started having games coming out on ten or so disks etc Just need an analogue telly know for the '81. 73 d'Alex, G7CGR; I make the CobWebb's!
