Boeing use common code and hardware in their CCS, it was one of the
reasons for the 787s delay, convincing the authorities that the code
was 'bug-free'

Airbus have always used seperate teams programming different hardware
running two different programming languages on their five flight
computers (3 primary, 2 secondary)

Thanks for that. I've updated my brain.

The ZX81 was very reliable - provided you raised it a little by standing

way.

Unfortunately by then physical books will be a rare commodity. Does
it work if you stand it on a Kindle instead?

Will posh schoolgirls balance Kindles on their heads?
Just a thought.

And how far can they walk if the power lead is connected?

I can't count! Anyway, it was enough for that particular application.

Everything from satellite receivers to computers seems to need
unplugging from the mains so often and plugging back in. How come? Why
don't they make these things so that when they're incapable of doing
their job they just automatically reboot? Couldn't satellite receivers
(for instance) just run some sort of self-check routine in the
background and if it fails do a reboot? (and come back on the same
channel of course?).



Why don't they just admit defeat and stick a reset button on the remote
control

Because if the device has frozen it won't be responding to the remote
at all.

I'd have thought it would be fairly straightforward to implement a
watchdog feature in a mass produced device.

Yes but you can buy a mains power saver that disconnects power to
peripheral units if the device on the main socket has been switched by
remote control to standby.
So put the crashing PVR / Freesat / Freeview box, etc on the
peripheral power socket and say the TV on the main socket, then
when you use the TV remote to switch the TV off and on, it'll also
switch power off and on to the buggy peripherals.

I think you have collectively answered my question. In summary, the
reason things crash is because they are built to a price.

In the standard model of the 'Western Market Economy' items are made to be
*sold*, not to be *used*. And almost no-one does any in-depth or long term
assessment of problems like rebooting due to crashes. By then, the next
'model' is on sale. As per the churning in markets like computing and
consumer electronics in general.

Witness also the shabby designs (in terms of *useability*) of so many brown
goods, despite often being functionally the same as items made for many
decades. Yet new models often re-commit past errors, or are worse than the
same maker's earlier examples. Often, the only think they want to learn
from previous models is what *sold* best. Not what works best. Or they use
a different design team who are clueless about previous achievements or
failures.

Slainte,

Doesn't that tend to negate the usefulness of a PVR :-)
