[9fans] plan 9 wiki experiment

[9fans] plan 9 wiki experiment

[Russ Cox]

I have set up a Plan 9 wiki.

A wiki is a web server that anyone on the 
internet can edit, traditionally by using 
a web browser.  The one I have set up is a 
bit different from the others since it can
be accessed either using a web browser or
using an Acme client.  The wiki itself is
provided by a file system (what else?) that
runs underneath the web server or underneath
the Acme client.  This means that it is equally
accessible to Plan 9 and non-Plan 9 users.

I have seeded the wiki with the contents of
the Plan 9 "Getting Started" document, but my
hope is that various readers of this list will
find it worth their while to fix up or add 
whatever they feel is wrong, unclear, or missing.
I think that collectively we can do a good job
of presenting useful information in an accessible
manner.  Recent converts especially may have a much
better feel for what needs more explanation than
is currently there.

There is, of course, a huge potential for abuse.
Please don't.  If the server fills with various
objectionable material, we'll take it down, and
I really don't want to do that.

The web interface is at 
http://plan9.bell-labs.com/wiki/plan9,
and you can download the Acme client from
the usual updates page.

Enjoy.

You know, I was going to say:

	Yeah, just look at Bell Labs: They're in New Jersey, but they
	still make some pretty beautiful software.

But then I realized that that wouldn't be funny except outside of
New Jersey.

Darn you!  That was going to be my project :)
Oh well, I'm sure you did it better than I could have.

Although a random nit is that, for the web interface, the generated links
point to

http://plan9.bell-labs.com/wiki/plan9/14

instead of

http://plan9.bell-labs.com/wiki/plan9/14/

or

http://plan9.bell-labs.com/wiki/plan9/14/index.html

which forces the browser to do a 301 Moved Permanently redirect to get the
real address every time you follow a link.

Very cool, though.

How about let-a-hundred-weeds-overgrow? :)  It's still better than monoculture
or toxic wasteland (although I guess you could say the current field has
aspects of both).  It's still possible to find or make beautiful things in a
toxic wasteland, even if it's not as much fun.

You know, I was at Murray Hill for twelve years, but every time someone
brings up the suburban horrors of New Jersey, I'm forced to remember
the first time I visited Bell Labs (July 1975.)  The directions we were given
were `From New York, get onto Route 22, go to the first MacDonalds, turn
right just past the arches, go right at the tee, up the hill to Mountain
Ave, etc.'  Now, the first MacDonalds was about a 20 mile drive through
the worst of strip-mall New Jersey, but after those two quick rights (past
the unmentioned cement quarry), we were in the beautiful woods of the
Watchung Reservation.  It was like something out of The Divine Comedy,
as we passed from the inferno to paradise...

The area has been built up a bit since then, but still, especially
when the leaves are falling in October, you can still get a little feeling
of entering a magic place as you climb the Watchung mountains to Murray
Hill.  (Of course, the gebrauchsarchitektur of the liquid nitrogen plant
and the lab buildings at MH pretty much destroy the illusion, but you miss
those if you go through the front door.)

Hmm....  The one and only time I was at Murray Hill was many years
ago.  I remember being particularly impressed with the stairs outside;
they looked like they'd be a lot of fun to skateboard on.

While I'm sure that New Jersey has some nice parts, the places I see
most frequently are pretty depressing (Hoboken, Newark, etc).  I must
admit, however, that my friend's place in Weehawken (opposite 42nd St)
is pretty nice and has a stunning view of Manhattan; better, indeed,
than any view one can get from Manhattan itself.

When I was at Penn State, one could avail oneself of some pretty
spectacular scenery.  I always thought that the campus itself was very
beautiful, as well.  I don't know how much it's changed since I left,
though.  Scott?

[9fans] KFS Crash

[Mark C. Otto]

I had bad addresses and 9p message start filling the screen.  Rio locked up, and
I didn't see any way to get out of it, so I rebooted.  Unfortunately, I couldn't
even boot up, not even with my boot floppy.


kfs...boot: nop...File system main inconsistent
Would you like to ream it (y/n)?        tag = <badtag>;Tdir
kfs init 5: FID1 attach to root
boot: read nop: file does not exist

8026bd54=801063a3 8026hd64=80171915
...
cpu0: exiting

Looks like I am going to have to reinstall the system, unless my terminal is
just trying to be sympathetic with Russ's. :-(  I have the following questions:

1. If rio crashes is there a way to kill rio and get back to the shell?
2. Given that I could, what diagnostics could I run to identify the problem?
3. Is there a way to repair the disk at this point?
4. Given that you don't have much faith in kfs and some of us are using it
exclusively on our standalone terminals, what sort of maintainance, such as
disk/kfscmd check, should we be doing?

> Would you like to ream it (y/n)?        tag = <badtag>;Tdir

It's kinda bad that it doesn't give you a chance to answer the question.
A kfs on a rescue floppy would at least let you check the filesystem
and maybe recover something.

[9fans] PS2 vs Com1 Mouse Problems

[Mark C. Otto]

I made the mistake of having a PS2 mouse and a serial mouse hooked up at
different times during the install process (indecision and a dearth of 3-button
mice).  My setup seems confused about which it has.  If I run echo $mouseport, I
get the proper ps2, but aux/mouse -n $mouseport returns

aux/mouse: can't open #t/eiapsctl - file does not exist

 From reading uart(3) p. 438, it seems to be treating the mouse as a serial
device and expecting $mouseport to be 0 or 1 in

bind -a #t/eia^$mouseport^ctl /dev

Not having a mouse or rio, this is hard to see where to correct this.  Thanks
for any help.

Mark

Re: [9fans] PS2 vs Com1 Mouse Problems

[Mark C. Otto]

At Russ's suggestion, I tried

aux/mouse ps2

which set the mouse.  My brain fart was using

mouseport=ps

instead of

mouseport=ps2

in my plan9.ini.  That fixed my problems with the mouse, vga, and rio (see
[9fans] Rio on Install but Not on Boot, Thu, 22 Feb 2001 08:04:22 -0500).  The
install went very smoothly otherwise.

Thanks Russ.

You are quite right.  It was my misunderstanding.

The right byte sequence of
もしもPlan 9で日本語を使いたいなら、私
are
[E3 82 82][E3 81 97][E3 82 82][Plan 9][E3 81 A7][E6 97 A5]
[E6 9C AC][E8 AA 9E][E3 82 92][E4 BD BF][E3 81 84][E3 81 9F]
[E3 81 84][E3 81 AA][W3 82 89][E3 80 81][E7 A7 81].

Anyway, thank you very much Russ, now we can use UTF-8 on your
Wiki server.  I replaced the bogus one.

  0x20 is not part of a valid UTF-8 sequence except when it represents
  a space character.  "[E6 97 20]" is not a valid UTF-8 sequence.

Right.  He was (intentionally or not) quoting the
munged UTF that was coming back from wikifs rather
than the original.  It was actually that UTF sequences like
日 [E6 97 A5] were turning into bogus sequences like [E6 97 20]
in the wikifs parse routine that condenses runs of whitespace into
single spaces.

Re: [9fans] plan 9 wiki experiment

[rsc]

I just fixed that, a minute ago.
I was dutifully using isspace() rather than
reinvent the wheel, and isspace() didn't work
on UTF bytes (with the high-bit set, it thought
they were negative).

So the return value on bytes in UTF sequences
was mostly bogus.  Retype the UTF, it should
stay this time.

I checked my UTF-8 document somemore bits, and found Wiki server may
transrate '0x20' to '0x0a', which destroyes Japanese text.

Like this,

I wrote (say, /mnt/wiki/22/index.txt),

もしもPlan 9で日本語を使いたいなら、私

the byte sequence of abobe sentence will be

[E3 82 82][E3 81 97][E3 82 82][506C616E2039][E3 81 20][E6 97 20]
[E6 9C 20][E8 AA 9E][E3 82 92][E4 BD 20][E3 81 84][E3 81 9F]
[E3 81 84][E3 81 AA][E3 82 20][E7 20 81][E9 81 20].

The runes which has '0x20' in that UTF-8 sequence are destroyed,
but the others are written right. Here, I enclosed one Kanji
character(rune) in [].

Couldn't we stop this translation from '0x20' to '0x0a'?

Wow, that's cool.  Thanks, Russ.  :-)

Much as I dislike the web, it can be pretty useful sometimes.

I put up an entry on how to install a 3rd edition file server.  It took
me a few attempts; I should have read the Wiki syntax guide before
going too far, and netscape is being my nemessis.  I would have used
the acme client, but my ricochet modem and ip/ppp don't get along too
well, so I had to use FreeeBSD and netscape.  Oh well....

Anyway, I wrote everything from memory, so I'm sure there are errors
and such, so please feel free, anyone, to edit it as you see fit.
Unfortunately, I'll be out of town for a few days and won't have access
to a computer until I get back, so I won't have a chance to apologize
for any particularly egregious errors myself.  :-)

Congratulations!
This is a very interesting experiment.

I access it by your Acme client, and tried to add a new Edit link, such as
Internationalization in the first page.  I chose 'New' menu command, and
set a first line as its title like "INTERNATIONALIZATION" and wrotea short
sentence below.  Then, I clicked 'put' command.  Can this new page appear?
