Fair enough but I am glad that I took a computer science degree (1971-74), though I must say that some of the people on my course who got better grade degrees used to come to me for advice when their programs did not work.
There is now a degrading of the term programming to include entering data on things like an on board computer of a car to configuring spreadsheets and designing web pages.
> How can BASIC not be taught? Every computer has it's own version of BASIC,
Sorry I have to disagree there. There are MANY computers including modern ones which do not support BASIC. If you restrict it to modern desktop and laptop machines then you are probably correct but you are ignoring many pre 1980 machines and nearly all the embedded computers like PIC chips.
A better choice would be C with the 1999 extensions. C++ is a good language but probably not for beginners as it is to easy to write opaque programs which beginners seem to think are good code because they are clever. As I hope all here would agree, a good program is the simplest you can write to do the required task, and that will mean it is easy to maintain (given adequate variable/function/method names and comments for the concepts you woke up with in the middle of the night).
Or Pascal. I think almost any block structured language is better for beginners than Basic.

A fairly recent study has shown that any reusable launch system would have to be used at a rate around 100 times that of the shuttle to be economically advantageous over an expendable system. I wonder how they missed that calculation back in the 70s? Each shuttle mission, no matter what it's carrying, costs as much or more than an ambitious multi-year robotics mission to Mars. And the $150 billion orbiting hotel in search of a real mission that sucks funds away from real space science, the ISS, should be disassembled and de-orbited immediately before it sucks even more money away from the robotic exploration of our solar system. Robotic missions not only generate vastly more scientific payback per dollar spent, but they don't risk lives and they develop robotic and AI technologies that are potentially useful here on Earth, too.
Here's an interesting 1974 popular Science article on what a bargain the Space Shuttle would be:

Hi folks,
any need for pdp8/e Omnibus memory?
Talking about
====> G104/H220/G227 (4K system) board triples without top connectors
The stuff is offered as tested working.
Not something "might have been pulled from a working machine (saw some lights when applying power)"
or "pulled from a working system a few years ago" or "was ok in 1983".
I'm checking the boards using the extended memory exerciser maindec-08-dhkma-c in my pdp8/e test
machine. Right now.
4 top connectors are needed for each triple. Sorry, but I cannot provide those at the moment.
Selling that on behalf of someone else. I promised to convert it to some $$$ for him.
Best wishes,
Philipp

But the items that are getting replaced are the wear items. No one
replaces the ECM in a car unless it breaks. Most don't.
My complaint about the amiga battery wasn't so much that it wore out,
but that it was soldered to the motherboard. And to add insult to
injury, it was a battery type that was prone to leak long-term.
Electronic systems should be designed with replaceable (without a
soldering iron) batteries. With a few notable exceptions (i'm looking
at you, ipod) they usually are these days.

Well, wait a minute, cars pretty routinely have people go under the
hood and replace stuff. If you look at caps the same way you look at
motor oil, the computers might deserve a little scheduled maintenance
too. And not many batteries have a service life measured in decades

When floppy drives were new, they usually came with that cardboard piece inserted, and with the drive door closed. When shipping a floppy drive, is it really best to have something closed in the drive? I'm talking about single head 5 1/4" drives here. I've seen several methods:
Nothing inserted, drive open
nothing inserted, drive closed
Disk inserted, drive closed
cardboard protector, drive closed
disk, in sleeve, inserted *sideways*, drive open (can't close it like that)
disk inserted backwards, drive closed.
Now, on a single head full height drive, there really isn't a whole lot to damage. The sping on the lever mechanism is pretty strong, so it's unlikely that it'll slam down and hit the head unless it's really dropped hard. And, if it does, it's just got a fuzzy pressure pad there - not another head. Also, with something as thin as a disk inserted, does it really protect anything? I suppose that the closed position is more stable, since then the mechanism would be fairly solid, and you'd have less chance of damaging the drive door, but would that mean any shock would press on the head?
A similar question would probably be - when single head full height drives were new, did they ship with a cardboard protector? I primarily only remember those from the half height and double sided drives. And only once have I seen one for a 3 1/2" drive (it was basically a solid plastic disk). And I also remember getting some new high density 5 1/4" drives that were not shipped with a protector.

If I am understanding the description correctly, this sounds like a
smaller version of the keys used on some VAG (Volkswagen, etc) cars. As
you imply, it's the hole depth that varies from key to key.

Same type of key used by late model Cromemcos (KABA Micro?).

About ten years ago the BBC made an official statement that when talking about money, a billion would mean a thousand million but elsewhere it would mean a million million.
To me a number is a number and that was b......t but the problem is US has a bit too much influence on broadcasting, you only have to look at the questions on the UK version of 'who wants to be a millionaire' where they asked what you would do with a 'brown betty' in a fairly low value question. The contestant and I guess 75% of the audience had no idea. Of course the other 25% might have just guessed randomly.
Actually there is really no excuse for creating confusion as they could just as easily talk about GigaPounds or GigaDollars or for 10^12, TeraPounds/Dollars.
I have no problem with the many americanisms in my life but to me numbers are sacrosanct. Just because a single US journalist made a mistake in the 1930s should not make us all roll over and play dead on a matter of principal.
