Comment: There are only 3 COBOL programs... (Score 3, Interesting) 318

The "Input and Validate"

At least that's what a lecturer told me many years ago when I did COBOL at uny. I didn't get on with it initially, then I got bored and opened the book... Then I learned that what the lecturer was telling me was his idea of what COBOL ought to look like and not generic. It got a little more interesting after that (along with the student competition to see how many errors we could make the compiler generate with the minimal amount of syntax errors - one mis-placed full-stop managed to get it to the limit of 999 once)

I've not written a COBOL program for over 30 years now. I don't miss it.

The price is affordable for "carriers" (ie. telcos and thererfore peanuts for mlitary), and you can buy true 1GHz full duplex units off the shelf today.

There is a problem with 60GHz though - range. It's the O2 absorption frequency, so max is 1-2Km...

However there are other frequencies in that area of the spectrum which I know are being investigated/used...

I recently bought an old Apple II.. And tried out some of the 30+ year old 5.25" floppies I had in storage all these years (I've got 100's). Most of them still work!

I'm suspecting that the bit-density is so low that it's hard for them not to work, but I was still plesantly surprised.

Now all I need is an Apple II serial card so I can get some of the source code for stuff I write way back then off the floppies onto something else...

They're a bit late then. There are already several kits out there - both breadboard and protoboard with solder holes in them. Get with the times!

Try this: http://shop.ciseco.co.uk/slice-of-pi/

Or this: http://www.skpang.co.uk/catalog/raspberry-pi-cover-with-breadboard-area-red-p-1071.html

etc. I currently have the SKPang one for my Pi.

I too am an N900 user... However after seeing my wifes HTC Desire, I suspect my mext phone might be the Desire with the keyboard... (HTC Vision) I've been a Nokia communicator user from day 1, but I think Nokia has somewhat lost the plot now - I miss the maps on my old N90 (the 3.5 year license expired!) and there isn't anything bundled with the N900 and it looks like there never will be. My wife seems to get on OK with Google maps on hers.... But it'll be a year or more before I'm ready for a new phone, so who knows what'll be out there then... G
