[9fans] EPIA platform from linuxbios

[ron minnich]

it's up to the point of DHCP'ing for its 'root is from' and I see the
packets, so the rhine driver looks good.

I will bring home my t21 laptop tomorrow (this is all on my dining table,
think I'll have to take a picture) and see if I can get it all the way up.

If this works, then booting plan 9 direct from linuxbios is a reality, and
I don't need 9load. Next step is to get that plan 9 in flash to do no more
than boot another plan 9; looks doable.

cool.

I think I'm writing XSLT and don't know it. I needed to transform some XML
to another form and wanted to use AWK. I found it inadequate and now I'm
writing my own thing. I think I'm an idiot but I looked at XSLT and ran
away screaming.

Aren't there pre-existing python modules that do that? Don't we have
a python port? Or is that an allegory, like Willy's beard?

where are you getting plan9.ini from?

[David Presotto]

I dinna know. That's why I posted to 9fans. I figure if I can do it in
a few days, its worth it. Otherwise I'll look harder.

I don't see the problem here. According to xslt.com, "XSLT enables and
empowers interoperability. "

What's not to like? Are you worried that we can't leverage synergies
across the enterprise with a dynamic, active transform that can
re-engineer our process structures for seamless interoperation of our
systems, thus giving us a bridge to the 21st century? Is that it?

Damn, I didn't even use a computer program for that previous paragraph.
It's up to you to prove that I didn't grab it from some web page
somewhere.

hey, I just timed it: power-on to root prompt, 7 seconds. And with a bit
more work I can get it down to < 5.

So think about this: on-demand computing with plan 9 means you just turn
off the CPUs until you need them, since booting them is not exactly a
lengthy process.

I was surprised to see how much more quickly Plan 9 came up than 9load
does. Not expected.

you're so picky. Plan.ini. Where's it from. Well. Hmm. Gee. Ah. .......
Should I tell you? Maybe you'll just get mad.

OK, I'll tell you: I don't use it currently. Just to get somewhere, I just
set all the options in main.c. I'm willing to do this as this is the
bootstrap Plan 9, so I'm ok with it; and besides, this little node is
basically sealed shut -- you could weld the case shut -- so plan9.ini is
kinda not a sensible thing in that case.

Sorry, don't get too upset with me :-)

which sometimes means: ``we don't understand each others' XML because
it's hard to do correctly and we hardly ever bother to check, so XSLT can
convert my XML to your XML so two things might work together once more''

that's before the arrival of SOAP. now your application is all washed up!

If I were facing a similar problem, I'd consider writing a simple
lexer that could convert well-formed XML into lisp sexprs, use lisp or
scheme to do the transformation, and then reverse-munge the resulting
sexprs back into XML.

I'm getting there...

yep. Or you can do what we do, look at XML, recover from the experience,
and just sexprs without ever using XML at all :-)

My only concern is that it hasn't been whiteboarded enough to ensure
compatibility with our core paradigms.

Phil Wadler has published some stuff on that topic.
Check out his web page.

FYI, there is this library:
