I surely hope the festive mood of the season will protect me from being
ostracized for asking this, but is there any chance to map Plan9
development practices to some of the established ways of source
code management? I mostly long for things like being able to browse
Plan9 history with a clear understanding of who did what and for
what reason.

exactly the same as plan 9 does.

as long as the fs supports a dump fs, 9vx will support yesterday.

for example, i've been mounting my diskless fs with 9vx. yesterday
works just fine. i'm sure you could use a linux-based venti with
plan 9-based fossil as well.

But yesterday won't work in a more lightweight environment (such as
9vx) will it?

Speaking of which
-- is there any FAQ on the current development
practices
of the Plan9 project? Things like patch lifecycle, etc.?

Thanks,
Roman.

Well, it is quite difficult to deny an audience to Mr. Murphy, isn't
it? ;-)

  [9fans] ahci improvement         


Author: erik quanstrom

i put a new sdiahci.c on sources that may help if you
have a hba with staggered spin up capability. i believe
ich9m does some pretty aggressive power mgnt. many
thanks to lucho for the patience to help work on the
problem.

  [9fans] alpha channel         


Author: Tharaneedharan Vilwanathan
Date: Dec 24, 2008 12:32

hi,
this is regarding alpha channel.

i am able to change the alpha value for an image by setting new alpha value
for every pixel.

but i was thinking we also could set the alpha value for all of the pixels
in a window/screen just but setting the value somewhere, say using ctl. is
this not possible in plan9 or inferno? i am wondering how i got that
thinking.

thanks
dharani

  [9fans] user login / plan9 terminal on plan9         


Author: Tharaneedharan Vilwanathan
Date: Dec 24, 2008 12:07

hi,
here is a quick question. let us say i am logged in as glenda or none. let
us say, i want a new window in which i need to login as vdharani. how can i
do this? in unix machines, i could do su, telnet or ssh and then login as
new user. i am looking for something like this.

years back i asked the same question and then ended up finding something
like 9term which was good enough (except that as i mentioned in the other
thread, if i started inferno in it, draw operations in inferno used to be
slow). once i found 9term, i realized probably drawterm is just like 9term
but for non-plan9 machines.

i am looking for 9term but i couldnt locate it.

any clues?

thanks
dharani

And I was so proud of myself.

Is this documented somewhere? the only reference to dma i found was in
the Supported PC Hardware page of the wiki, which suggests editing
data.c.

Speaking of the wiki, I notice that the instructions on the Acme Wiki
Instructions are not working? There are some links on the site that
are broken, ( e.g. the installation notes link on the http://plan9.bell-labs.com/plan9/
page points to http://plan9.bell-labs.com/wiki/plan9/installation_instructions/
instead of http://www.plan9.bell-labs.com/wiki/plan9/Installation_instructions
) and I thought to help fix that

In any case, my system is now mostly idle and is no longer generating
tens of thousands of interrupts per second.

  [9fans] fn oddity with acme         


Author: Mathieu
Date: Dec 24, 2008 09:53

Hi all,

I've defined such an rc function:
fn acmef { acme -f /lib/font/bit/fixed/unicode.8x13.font }
and when I call this function I keep getting this error displayed
repetively on the screen:

grow segment 3 -> f00000 would overlap 0 [f000000-10000000]

this happens both with p9p acme/rc and in 9vx.

Am I doing something that I am not supposed to here? I defined other
simple functions like this one in the past and it always worked so far.

Cheers,
Mathieu
