Morning Malcolm,
I have now registered with both Farnell and RS, which was all very easy
to do. The former are offering a 'free' special edition Rpi T-Shirt, too
... :-)
I've seen those - element 14 I think.
OK ... with Linux it all seems an endless series of 'flavours' of Linux.
It may look that way but Linux, or more accurately GNU/Linux is the
kernel, the actual OS if you like. That's pretty much standard across
all distros. A few distros do modify the kernel slightly to match their
needs, but usually it's in non-important areas.
The distro itself comes in many flavours, including the applications
supplied, the GUI in use - KDE, Gnome, Gnome3, etc. This doesn't mean
that if you use Linux Mint with Gnome that your applications won't run
on OpenSuse with KDE - they will.
OK ... you get some 'basic' stuff, and then post-install a lot of other
potentially more useful stuff.
Sort of. With Windows you install everything (ie, the OS) and then start
buying applications, or downloading Firefox, Chrome, whatever from many
different places. How secure these places are, you have no idea.
With Linux, everything is on the DVD initially, and part of the
installation set you up with repositories and it is from these that you
get your new stuff, updates, patches and so on. These repositories are
secure in that they use security signatures and certificates to prove
their validity.
Ah ... yes ... fault tracing in electronics is like de-bugging in
software ... a potential long and tortuous road.
It came to me this AM when I was in bed what I'd done wrong. I need to
check later to see if my subconscious was right. My two timing resitors
needed to be around 1K and 144K to go with the 100nF capacitor. I have a
funny feeling that I used a 980K instead of 144K - major failure there
for "around 144k"! ;-)
Umm ... you may say that a lot of hardware and software has been sold to
Schools ... :-) ... but then, we are not cynical; are we?
Most of our schools are "sponsored" by Microsoft. As is most of
government. We are doomed to repeat the errors of our predecessors if we
never learn.
And yes, "we" are cynical, with good reason I'm afraid! ;-)
Hope you get your Pi soon.
Cheers,
Norm.
