Am I on the wrong list for posing basic questions about Linux? I posted a question a few weeks ago about about not being able to copy files because of permissions and because filename had a '?' in it. I received no response. I understand everyone is a volunteer. I'm not complaining - just want to know if this is an appropriate forum for basic questions. I know it's wrong to piggyback on this thread, but it is getting a lot of traffic, so I had no choice. Do I keep posting, and just see which posts are of interest to people, and which questions are not? Sorry, I'm not one to take a hint or "know" when to leave a party. I need someone to say, "Chris, leave the  party." :)

Any Raspberry Pi would do for what you just said until you get to the last
line.

If you don't care about kernel build time, I *guess* that any Pi would do,
but I don't know.

I do very much care about the build time. I was thinking of cross compiling on my
ancient desktop then moving it to the Pi ?

You don't need two monitors so you can remove that cost.  You can probably
use your old monitor, keyboard, and mouse (you might need dongles to
convert between old and new standards).

Agreed all I need is a single monitor.

What are the specs of your ancient desktop?

Well.. like I said pretty old my bios is:
cat /sys/class/dmi/id/bios_date
07/05/2013

and lscpu shows:
Architecture:          x86_64
CPU(s):                4
Thread(s) per core:    2
Core(s) per socket:    2
Vendor ID:             GenuineIntel
Model:                 60
Model name:            Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz
CPU MHz:               3389.375
CPU max MHz:           3400.0000
CPU min MHz:           800.0000
BogoMIPS:              6784.89 

and free -h shows:
             total       used       free     shared    buffers     cached
Mem:          7.5G       5.2G       2.3G       341M       163M       2.1G
-/+ buffers/cache:       2.9G       4.6G
Swap:         902M         0B       902M

it's not a bad system I just want to start messing with a Pi :-)



Most ancient desktops are actually more powerful than a Pi.  For some
meanings of "ancient".  If yours is really ancient, I would guess that
there is a cast-off PC that is less ancient.

If you put a premium on "cute" and don't mind the various inconveniences,
a Pi can surely be used as your main general-purpose desktop.

Thank you for all the pointers and advice.
